In 1974. the Real E s tat e R esearc h Corpo ration published a threevolume study entitled Tire Costs of Sprawl. The study consisted of an Executive Summary, Detailed Costs Analysis (Vo lume 1}, and Literature Review/ Bibliography (Volume II). It encom passed more than one tho u sand pages. From the time of its publication until today. it has been regarded by the soc ial science community as one o f the most sig nificant critiqu es of spraw l and among the mos t influential studies eve r under taken. The Costs of Sprawl tlas been cited in countless environmental and planning reportS and journals; it has been reviewed-both positively and negatively-by more than one hundred journals and magazines ; and it has been presented as the seminal study o n growth impa cts to num erous Congressional co mmittees and bodi es.

residences, automob i les, and suburban li festyles, there is a nagging feeling that both the aesthetics of how communities develop and the efficiency of movement within and between them could be improved. In addition buried down deep is a recognition that Americans arc wasteful in their consumption of manmade (infrastructure) and natural (land) resources and that their development choices are selfish in terms of impacts on central cities and the populations within them But first it must be shown to the citizenry at large that there is a problem, because life i s good and "If i t ain't broke, don' t fix it.'' Is suburban sprawl different from an alternative form of development? Is it less efficient? Does it cause resources to be needlessly consumed? Is there an alternative? What do those who have studied this issue say? How substantively strong is the evidence they bring to bear? The s t udy that follows is a detailed examination of most of the information that can be assemb l ed on both sprawl and its costs in an effort to answer the above questions. The monograph views the costs of sprawl (with l ower case lett ers) as investigated in a variety of types and forms of about 500 studies These stud i es vary between those t hat: (I) focus specifically on sprawl, and those that deal with suburban or ex urban development; (2) are highly quant i tative, involving modeling or econometric analyses, and those t hat are qualitative and purely descriptive; (3) concern the "harder" or physical/engineering aspects of sprawl, and those that substantively involve "softer" or quality of life/social issues; ( 4) are primary analyses and break new ground, and those that are secondary analyses of the works of others that add R:..ngn Brookings Potlb n.s 8rindcetflolf ECONorthwe d IV very little; and (5) vilify sprawl and see no positive effects, and those that cham pion t h e development form as pure l y and unequivocally "American" with few, if any, negative impacts. With regard to the Iauer, this assemblage of material identifies and provides evi dence for both negative and positive impacts of sprawl in each of five impact areas. These are: public and private capitol and operating costs; traiiSportalion and travel costs; landlnaturallzabitot preservation; quality of life; and social issues. The work contained in this monograph is divided into five chapters. Chapter One contains an introduction to the concept of sprawl, including bo t h its defining trai t s and what is meant by the "costs" of sprawl. Chapter Two highlights signi fi cant events i n the history o f the evolution of the sprawl literature. Chapter Three divides the alleged impacts of sprawlmore than 40 in total, two-thirds negative and onet hird positive--into the above five categories and detennines whether evidence from the literature supports the impact and its direction, as well as its association with a land development pattern termed sprawl. Chapter Four individually analyzes and annotates about one-quarter of the sprawl studies Chap ter Five classifies the sprawl literature by category and method of analys i s. The review of the sprawl literature is designed to be historical, substantive, comprehensive, and integrative Presented in this way, the reader will be drawn into the argument about sprawl from its origins to the present TRANSIT COOPERAOVE RESEARCH PROGRAM (TCRP) H lO

1 INTRODUCTION AND DEFINITION INTRODUCTION The literatu re review that follows is an analysis of the writings and studies con cerning a pattern of land development in the United States termed "sprawl." Sprawl is the spread-out, skipped-over development that characterizes the non central city metropolitan areas and non metropolitan of the United States. Sprawl is two-story, single-family development on lots ranging in size from one-third to one acre (less acreage on the West Coast), accompanied by strip commercial centers and industrial parks, also two stories in height and with a simi l ar amount of land takings (Ewing 1997). Spraw l occurs oo a micro basis i n almost every county of the United States (although it occurs in significant amounts in only about one-quarter of the nation's 3 ,000 counties). Most U nited States counties that contain sprawl have it in itS residential form-i.e., low-density residential development in rural and undeveloped areas. Some counties are characterized by nonresidential sprawl, commercial and industrial development with floor -ar ea ratios less than 0.2 located 1 in the same types of areas (Burchell and Shad 1997b). Sprawl is the spread-out, skipped-over development that characterizes the non-central city metropolitan areas and non-metropolitan areas of the United States. -Ewing 1997 Sprawl occurs because local governments in the United States encourage this form of development via zoning and sub division ordinances which, in tum, reflect the desires of the citizens. This type of development is favored by the general public because it (among other factors}: I} distills congestion while accom modating unlimited use o f the automobile; 2} distances new development from the fiscal and social problems of older core 3} provides a heterogeneous economic nux; 4) fosters neighborhoods in which housing will appreciate; 5} fosters neighborhoods in which schools provide both education and TRANSIT COOPERAnVE RESEARCH PROGRAM (TCRP) HlO

appropriate socialization for youth; and 6) requires lower property taxes t o pay for local and school district operating expenses than locations closer in. (Burchell 1997a) Sprawl is so well-accepted by the public that the AAA-rated locations for both residential and nonresidential devel opment are increasingly farther out rather than closer in, and more rather than less segregated by type of land use (Gordon and Richardson 1997a).

The big-ticket item in all infrastructure projections is roads In South Carol ina, roads are expected to cost S25 billion, almOSt half of the tOial $56 billion infrastructure budget. ln South Carolina, roads will cost 2.5 tim es what will be spent o n primary, secondary. and higher education infrastructu re; three times what will be spen t on h ealth infrastruc ture, including all hospitals, institutions, and all water-sewer treatment systems; ten times what will be spent on public safety, administration, and justice infrastruc ture; firteen times what will be spent on environmental protection infrastructure; and twenty-five t imes what will be spent on all cul tural and recreational infras tructure 3 Duall y supporting and ullderutilizing two systems of infrastructure-one that is being abandoned in and around central cities and close-i n suburbs, and one that is not yet fully used in rural areas just beginning to be developed-is causing governments to forgo the maintenance of much infrastructure and the provisio n of anything other than growth-related infrastructure. The United States, in other words, is funding road infrastructure by: I) not funding all 2) not fully funding developmental infrastruc ture ; 3) not repairing or replacin g mo s t types of infrastructure; and 4) not taking advantage of the techno logical improvements in rehabilitation, repair, and provision of infrastructure that could be passed on to t axpayers as savings. Still, by no means is an alternative t o the current pattern of land development the ultimate panacea. If South Carolina were to switch to compact developm ent and managed growth measures to curtai l spread development, the state would be able to save only about 10 percent of the pro jected $56 billion infrastructure costs, or approximately $5.6 billion. This is because about 40 percent of public infrastructure costs are not growth related, and only about two-th irds of the remainder i s new growthrelated. When development pauern savings are applied to the appro priate portion of new growth related infrastru cture costs, therefore, the saving is only 12-15 percent. On the other hand, increasing the gasoline tax by 2/gallon raises only $56 million in new revenues statewide-<>ne one thousandth of the total required infrastructure costs-and one one hundredth of the amount that potentially could be saved by altering land development patterns (Burchell l997b) TRANSIT COOPERAnYE RBEARCH PROGRAM ITCRP) H-10

7he Cosfs of Sprowf.....Revisited In sum, the majority of the American public i s not unhappy with the current pauern of development in metropolitan areas-it simply can no longer afford it. Thus, the primary concern about sprawl development. at a time wben tbe average American is satisfied with its outcome, is cost And costs need to be measured not just in terms of capital improvement but also in terms of resource depletion. Land in the United States is being consumed at triple the rate of household formation; automobile use is growing twice as fast as the population; and prime agricultural land, forests and fragile lands encompassing natural habitats are decreasing at comparable reciprocal rates (Landis 1995). In sum, the majoriJy of the American public is not unh4ppy with the current pattern of development in metropolitan areas-it simply can no longer afford it. As a result the professional transportation and city planning communities are beginning to look at sprawl to determine whether an alterna tive to this growth pattern can be con ceived, and even m ore importantly, whether it makes sense to pursue an alternative pa ttern o f growth. Does any altemati ve pose a viable option to current methods and forms of metropolitan development? A significant literature has developed in this area and is briefly overviewed below. CURRENT SPRAWL ANTECEDENTS Sprawl, in broadest sense, has long been an American zeitgeist. Aleltis de Tocqueville, touring the United States in the early 1800s, observed "no urban growth boundaries," but rather m arveled at "America . where everything is in lntrodudion/Oefini tion constant motion .. and where no boundaries were set to the efforts of man." Today's sprawl is the frontier of long ago; it is akin to the post-war suburb-both of which have been extolled as defining American influences. John Delafons, fellow at the Harvard/MIT Joint Center in 1961. chose as a research top i c a comparison of British and American land-use controls. His work, Land Use Controls in America, provides an insightful look at the growth of tbe U.S. "system" of controls from 1920 to 1960 by an outsider who came from a country with a very formal system of land use controls. Delafons describes the U.S. system of master planning, zoning, and subdivis io n control as heavily influenced by a "prairie psychology ." He explains that U.S. development patterns are characterized by: a) a supply of land which is viewed as virtually unlimited; b) land that is open to all and property ownership that are encouraged and protected by the U.S. Constitution; c) economic forces that arc barely understood and should not be tampered with; d) development professionals who prepare land for development and do not question whether the land should be developed (i.e., they make sure utilities are in place and feeder roads hav e been planned for); and e) a basic distrust of elected and appointed officials, so that all procedures arc codified and development that qualifies under these procedures does so "as of right," with minimal public review. (Delafons 1962) TRANSIT COOPERATIVE RESEARCH PROGRAM (rCRP/ H-10

PAGE 12

U.S. de v elopment controls, he claims, are "static" and thus lack the ability to control tempo (timing) and sequence (which location first) of development. Development is free to wander and to take place incrementally in jurisdictions in the United States because existing land use controls allow this to happen (Delafons 1962) Many agree with Delafons i nsight Althoug h some view contemporary development patterns as a reflection of the invisible but sure hand of the market (Gordon and Richardson 1997a), the unbridled movement outward of leapfrog, low-density development is increasingly being viewed as an American ill (Richmond 1995). Sprawl has taken on both a pejorative as well as a descriptive connotation, an intermixing that makes a balanced discussion. wbich attempts to disentangle the costs and benefits of sprawl, difficult. U.S. development controls are "statk" and thus lack the abUuy to control tempo (timing) and sequence (which location first) of development. The shift to the suburbs has, of course, been manifest for more than half a century. In 1940, only 15 percent of the United States population resided in the suburbs (defined as metropolitan areas of central cities). As the millennium approaches, about 60 percent of the population is counted as suburban. Even the most vehement critics of sprawl recognize that suburban and ex urban growth patterns have been and will continue to be inescapable development forms in the United States. The recent population increase of some 20 million people per decade is likely to continue for at least the next quarter-century As a result, there will continue to be skipped over development in rural and 5 lntroduction/Defln.ition undeveloped areas. It would be totally unrealistic to expect even a moderate share of growth to occur solely in already built-up neighborhoods in cities or in close-by in. ner suburbs. Even the suburbs are being bypassed now by development seeking locations at the fringe of metropolitan areas (Nelson and Sanchez 1997) A WORKING DEFINITION 01'' SPRAWL Density, or more specifically, low density, is one of the cardinal defining characteristics of sprawl. But dens ity bas to be set in context; cross-cultural and place-oriented differences factor into the definition of sprawl. Densities in the United States overall are roughly one tenth what th ey are in Western Europe; in tum, Western European density is much lower than that of Japan and only a fraction of what is found in such locations as Hong Kong and Indonesia (Jackson 1985). And in all of the above locations, suburban densities are lower than the densities of central cities. Sprawl is no t simply development at less-than maximum density; rather, it refers to development tha t, given a national and regional framework (i.e., suburbs in various locations of the United States), is at a low relative density, and one that may be too costly to maintain. Sprawl refers to a particular type of suburban peripheral growth. It refers to development that expands in an unlimited and noncontiguous (leapfrog) way outward from the solidly built-up core of a metropolitan area. In terms of land-use type, spmwl includes both residential and nonresidential development. Residential development contains primarily single family housing including significant numbers of distant units scattered in outlying areas.

by automobiles in rural and undeveloped areas. this i s the point at which almost all tracking stops. Measures of leapfrog development or development that is spatially segregated are virtually impossibl e Measure s of how much development is being delivered by small developers in local jurisdictions is achievable but generall y unproductive. Finally although a measure of gross residential den sity ( number of dwelling units divided by area of jurisdic t io n ) is available from several sources and can provide some indication o f land taken per developed unit, the gross measure often masks the actual land takings of individual new developments On the otll hand there is lillie evidence to s ugges t that conventional developmen t in a given location is anything other than leapfrog, segregated, and land cons uming. Thu s, sp r awl develo pment can be characteriz ed with some certainty as low-density residential and nonresidentia l intrusions into rural and undeveloped areas. and with less ce rtainty as leapfrog, segregated, and land-<:onsuming in its typical form. A WORKING DEF I N I T ION OF T H E COSTS OF S PRAWL The "costs" of sprawl have bee n talked about for decades often without a full understanding of what these costs are and to what level they should be assigned In the original RERC ( 1 974) Costs of Sprawl study. costs were cal c ulated in six differen t substantive areas and assigned t o three different le ve ls: infrastructure and transportarion costs were assigned to the conununi ty, housing and quality-of life costs to the indi v idual, and ene rgy and environmental costs t o both the com munity and to society as a whole (RER C 1974). This is a characteristic of the sprawl literature which i s only beginning to be addressed at the end of a twenty 7 lntroduc&"(Dfini.'tion five-year observation peri od. The work of Sam Seskin of Pars ons Brin c k erhoff and Teny Moore of ECO Northwest o n full-<:ost accounting of tran s portation costs is breaking new ground in viewing the totality of costs of public policy deci sions (Parsons Brinckerhoff and ECON o rthwest I 996). Their work is the exception. Most cost accountin g ef!ons assign sprawl costs to either the easiest or the most common level of For definitional purposes, the "costs" of sprawl are the resources expended relative t o a type, density, and/ or location of developmem These "cost s" invo lve phy sica l monetary, temporal and sociaVpsyc hological resources Th e y involve c osts to the i ndividual, t o the community, and to society. Mo s t of the costs spec ified to date are physical or monetary, alt hough occasionall y socia l costs (e.g., the loss of upward mobility) or psychological costs ( e g ., the loss of sense of community) are documented. There is little evidence to suggest that conventional development in a given location is anything other tla an leapfrog, segregated, attd land-consuming. 'J"M "benefits of sprawl are mirr or ifiUiges of costs. They involve resource gains due to type of development pallem and include categories of gain similar tO those of losses stated above. This might involve a temporal gain i n suburb-to suburb travel time because mo s t residences and jobs are now both suburban, or monetary gains due to reduce d housing costs from building farther out, or social gains such as the ability t o achi eve bomeownership, again due t o location in more distant plaoes. Costs and benefi ts are reported in the f orm t hat the primary research provides In almost all cases, these are costs at the community level as opposed to cos t s at the i ndividual or societal levels, or benefits at any level.

O.orvitw/H i>lory 2 OVERVIEW AND HISTORY OF THE SPRAWL LITERATURE EARLY CONCEPT U ALIZATION OF THE T ERM "S P RAWL" AND EARLY C RI TI C I SMS Sensitivity to the consequences of spraw l-like settlement predates the coining of the tenn. The 1929 Regional Plan of the New York Metropolitan area, for instance, warned of a steady decrease in farms and open-space acreage in the region and underscored the need for settlement patterns that encourage d "the face to face association that characterized the old village community" (Regional Plan 1929,23 and 216). At the same time, the Regional Plan spo ke approvingly of "many carefu lly planned outer subdivisions with good features" (Regional P l an 1929, 1). Concern about sprawl-like patterns of development was appropriate at this time. The Standard Zoning Enabling Act ( 1922), drafted under the aegis of Secretary of Commerce Herbert H oover, the Standard City Planning Enabling Act (1928), and the legal.ization of zoning that resulted from the 1926 Supreme Court decision (Euclid v. Amber Realty) unleashed a barrage of "model" zoning 9 and planning-enabling legislation across the United StateS. Euclidean zoning of segregated land uses and the emergence of the automobile began t o establish the first distant "suburbs" throughout the United States. It was not until roughly the lat e 1950 s and early 1960s, however, that sprawl as a planning tenn entered the literature. The land development pattern it depicted was typically criticiz ed Herbert Gans in 11tt uviuowntrs described Levittown development of the 1950s as "residents living in a sea of cell -like structures on a Levittown, Pennsylvania: post.\Vorld War II suburbia.

remote potato farm with cars spilling out of every street (Ga n s 1967). In 1956, a Canadian planning study described urban sprawl as "scattered building development" that had led to "inconven i ences in the placement of public and business facilities" (Lower Mainland Regional Planning Board 1956). A year later, William H Whyte, describing urban sprawl as leapfrog, scattered development, spoke of it as "a problem that had reached national proportions" (Whyte 1957). The political and social climate of the period, however, provided definite financial i ncentives for building homes i n the suburbs in the form of federally insured low-cost mortgages. This period also witnessed the massive federally subsidized expansion of U.S. highways ( 1956/nterstate Highway Act), including the establishment of the interstate system. The new roadway system, together with the growth in acces sible, mortgages, helped push development fat beyond the nation's central cities (APA 1997). Rela tively few people seriously challenged this new pattern of growth in the outlying areas or questioned the ch anges in central cities brought about by multi-lane freeways. Others soon entered the discussion, however. Marion Clawson, in 1962, described sprawl as a "lack of continuity in expansion," and noted it was both fostered by and contributed to, la n d spec ula t ion (Clawson 1962). Similar literature of the period, including Lessinger ( 1962), Harvey and Clark (1965}, and Bah! ( 1968} viewed spraw l as characterized by such features as low density, scatlered. and leapfrog patterns. H arvey and Clark ( 1965) identified the three cardinal traits of sprawl as low density, ribbon, and leapfrog development. Oter"'iew/HidOfY Even at this early stage, pundits acknowledged the difficulty in defining the term sprawl. Writing in 1972, David McKee and Gerald Smith observed that: Urban sprawl is rather difficuh to define. In some circles the term is thought to be synonymous with sub urbia. Certainly the problem exists in suburbia but suburbia itself is not the problem. Some equate sprawl with expansion. But this type of definition is not too helpful. (McKee and Smith 1972, 181-182) McKee and Smith went on to de scribe spraw l in four fonns: I} very low-density development (i.e., t woto five acre zoning); 2) ribbonvariety development extending along access routes: 3) leapfrog development; and 4} a "haphazard intermingling of developed and vacant land" (McKee and Smith 1972). The authors claimed that sprawl aggravated suburban problems (e.g., automobile dependence and the high cost of services and infrastructure) and also deleteriously affected cities by d e pressing real es tate values, among o t h e r things. The political and social climate of the period provided definite financial incentives for building homes i n the suburbs. Discu ssion of sprawl's effects tran scended economics. Although the 1973 R ockefeller Brothers Task Force publication, The Use of lAnd, did not speak of sprawl per se, it concluded that the dominant pattern of "unrestrained, piecemeal urbanization" was leading citizens to ask how such growth affected their quality of life" (Reilly 1973, 33). In a similar vein, The Langu.age of Cities and the Encyclopedia of Community Pl.anning and Environmental Management defined sprawl respectively, as: 10 TRANSIT COOPERATIVE RESEARCH PROGRAM (TCRP) H-10

the awkward spreading out of the limbs of either a man or a community. The first is a product of bad manners, the second of bad planning. Sprawl is a by-pr oduct of the highway and aut omobil e, which enabled the spread of development in all directions. As builders scrambl e for l ots to build on, th e journey to work is l eng thened and gree n spaces are co n sumed b y g as stations and clu uer.

(Schultz and Kasen 1984. 378-379) THE FIRST STUDIES ON THE COS T S OF S PRAWL I n the 19 60s p rofessional research began to be undertaken in numerous areas relevant to the study of sprawl. Examples of this early research include Innov ation Versus Tradition in Community Develo pment (ULI 1963}, which loo ked at the effec ts of developm ent patterns on r oad lengths; Howard County Study (Howard County 1967 }, whi c h con si dered comparative countywide costs of roads, u tilities. schools, and open space under sprawl versus more planned scenarios; Urban Fonn and the Cost of Public Servi ces (Kain 1967). which considered public service costs at varying densities ; Planned Residential E nvironments (Lansing 1970), which looked at how different overall development patterns influence trip 1 1 generation rates and distances ; Toral Energy Demonstration (HUD 1 972}, which measured lik e ly savings i n energy consumption in planned communitie s; and The Relationship of Land Use and Tran.rponation Planning to Air QuLility M anagemem (Hagevilc 1972), which examined how development pl a nn ing affects air poll u tion on a regional basis Although not articulated, the substantive foci in analyzing sprawl versus alternatives-namely, the issues of transportation, infrastruct ure. public service costs, and land and environmental issues-were already being formulated.

The Com of SprowJ-R.evisif9d that sprawl development had at least two major traits: low average residential density (3 unit s or less per net res idential acre), and a lack of overall planning at either the regional or community level. RERC did not define sprawl's specific density characteristics, nor did it defme its residential and nonresidential components. RERC considered approximately 20 individual effects (see Table 1). As seen in Table 2, the se costs can be grouped into four overall categories encompassing: I) public private capital and operating costs; 2) transportation and travel costS; 3) land and natural habitat preservation: and 4) quality of life. Not considered in The Costs of Sprawl, and not part of its research charge was any examination of sprawl's social effects, such as its on cities. } 'he of ... :21)_'1 in'ilividual -elfect}.'"f -' : The RERC study evoked a flood of commentary-much praise as well as some criticism. Two of the better known criticisms were articulated by Altshuler (1977) and Windsor (1979). Among other points Altshuler argued that RERC underestimated the demand for services by higher-density development and commingled the effects resulting from high density and small.er-unit size. Windsor, in paraJJel. criticized RERC for not disentangling density from other factors, and among other shortfalls, argued that RERC ignored the benefits of sprawl, such as its "response to consumer preference" for single-family detached homes. These early points of opposition on the costs/benefits of sprawl 12 Overvlew/HisiOt)' are still present twenty years later and can be seen in the recent exchanges herween Gordon/Richardson and Ewing on the subject (Gordon and Richardson 1997a; Ewing 1997). Not considered in The Costs of Sprawl, aiul not part of its research charge, was any examination of sprawl's social effects, such as its impacts on cities. Although the findings of The Costs of Sprawl dominated the literature for some time, new analyses continued to he published. Examples include David Popenoe's (1979) depiction of sprawl as low-density, scattered strip development, which focused on its adverse sociologica l implications. In 1981, David Mills described sprawl as scattered, leapfrog development, and discussed how it both abetted and resulted from land speculation. THE INTERIM STUDIES: MANAGED GROWTH COSTS IN CALIFORNIA; THE COSTS OF SPRAWL IN FLORIDA (DUNCAN AND FRANK) I n the early I 980s, in response to the rampant development of the 1970s, growth control ordinances began springing up in California and Florida cities. These included Davis (CA), Petaluma (CA), and Boca Raton (FL). Before one or more of these ordinances were challenged and set aside, initial inquiry concerned their p otential impact on local housing costs. If growth were curtailed through building permit or population caps or through adequate public facilities ordinances, would these factors contribute to increased housing costs? Almost everyone looking at these issues concluded that growth control ordinances did increase local housing TRANSIT COOPERATIVE RESEARCH PROGRAM (TCRP) H-JO

J ames Duncan, a consultant working for the Florida Department of Conununity Affairs, studied the capital infrastructure requirements of sprawl (scanered) versus compact development forms.

CHARACTER I Z I NG SPRAWL: C R A B GRASS FRONTIER S AN D EDGE C I TIES Kenneth Jackson's Crabgrass Frontier: The Suburbanization of the United S t ates publis h ed in 1985, received much acclai m. Although s prawl per sc was not mentioned in thi s monograph, numerous traits attributed by Ja ckson to the :crabgrass frontier" were clearly s prawl like m character. These attributes were: 1) low reside ntial density and the absence of sharp divisions berwcen town and country 2) the so c ioeconomi c di s tinction betwee n the center and the periphery 3) a lengthy journ ey to work in t erm s of distance and time Jackson attributed the permanence of the crabgrass frontier to physical as well as political factors ( e .g., that America was land-ric h and had fmgmented local gove rnments). He also noted its problem s (e.g., high local publi c servic e costs and increased automobil e d e pendence) as well as its benefits (high l eve l of housing amenity and in di vidual ope n space).

SPR AWL AND CIT IES: D OWNS RUS K AND BAR NETT In his 1994 book, New Visions for Metr opolita n America, Anthon y Downs adopted a broader approach for defining sprawl that primarily referred to density but included some other characteristics as well. Downs, building on an earlier w ork St u c k in Traffic (Downs 1 992), defined s prawl as encompassing five major elements: TRANSIT COOPERATIVE RESEARCH PROGRAM (TCRP)

Downs described a way of formulating alternative outcome s through an analysis of the basic traits of different growth strategies Downs's approach is incorporated and described in m ore detail late r in Chapter 3. As is apparent. even the most cwrent literature on sprawl tends to describe its attributes rather than quantify them Very few quantified analyses of sprawl's impacts or relationship s to other variables appear anywhere in the literature. As a result, few studies have mathemati cally or s t atis ticall y link ed sprawl to other conditions or metropolitan traits. A limited attempt at quantification was put fonh in the 1993 work by David Rusk in Cities Without Sub urbs. He calcu lated an "index of elasticity that measured the ability of c ities to extend their boundaries to encompass surrounding wbaJtized development. "Elasticity" is essentially the same as annexation, i.e., movement outward from the city cent er (sprawl) without the creation of new political jurisdictions. R usk claims that cities with high indices of elasticity are superior to 16 tho se with low ind ices of e lasti city, in terms of income distribution, racial integration, populatio n growth, and economic development. The best CJl!es are "elastic" cities, he claims, and applies his index both to cities themselves as well as their metropolitan areas. Rusk himself did not perform mathe matical or statistical analyses relating the variables just described, but three re. viewers of his book d .id. John P. Blrur, Samuel R. Staley, and Zhongcai Zhang (1996) used multiple regression employing measures of growth and economic welfare over the period 1980-1990 as independent variables, against Rusk s index of el asti city as the dependent variable. These reviewers con cluded that Rusk's index of elasti city had statistically significant effects of the expected types on city employment, The most current literature tends to de sc ribe s prawl's attributes rather than quantify them. population, poverty, and per capita income growth and significant effects of the expected types on metropolitan area population and employment growth-:but not of the expected types on metr opolitan area per capita income or poveny growth H owever, even where the regressi o n equations identified st atistically significant effects, they had low R1s Oow explanatory power), an outcome that indicated that other unspecified variables were possibly not included in the regression equation An implication of this analysis was that either Rusk's index of elasticity is not a useful indicator of sprawl or the indicator itself due to its constructio n, inherently produced low levels of explanation City-suburban relationship s were also considered by Jonathan Barnett 10 his 1995 book, The Fractured M etropolis.

This analysis of meuopolitan area uends is strictly narrative and advances the thesis that U.S. metropolitan areas are s plittin g into "old cities" and "new cities." Barnett proposes that future growth be redirected intO the "old cities. Much of h is work is s kewe d towar d physical de sign and planning; i t favors compact development over sprawl and encourages commercial development within. and the cre a tion of urban growth boundaries around. old metropolitan cities. SECOND GENERATION STUDIES ON T HE COSTS OF S PRAWL Research i nto meth ods t o add ress the costs of sprawl and a s tudy of the underlying data have been undertaken at both the Center for Urban Policy Research at Rutgers Unive rsity and at the Uni v ersity of California-Berkeley. Starting in the early 1990s, Rutgers University researchers, led by Robert W. Bu rch ell. beg an to quantify th e relative impacts of alternative patterns o f development. One or two years later, under John D. Landis, similar effortS were undertaken at the Institute of Urban and Regional Development at Berkeley. Both research organizations have looked at the prospective impacts of alternative deve lopmen t pattern s. Both research organizations dev elope d c omprehe nsive land use mod els to carry out these analyses (Burchell 1992a, 1992b; Landis 1994 1995) Costs are defined primari l y in terms of resource consumption at the community level.

The results obtained are show n in Table 3. This Rut gers stud y was preceded by similar work for the State of Maryland as pan of its original attempt at a Growth M ana gement Act.

The land-use liter ature describes this type of development a s skipping over existing development: land-consumpt ive and inefficient use of available land at or near the core of the metropolita n and requiring s i g nificant accom panying infr astmcture in the form of roads, water and sewer lines. public buildings, and the l ike. Compact, or a more managed, type of de,elopment attemp t s t o direct growth to already existing locations of development while preserving yet-to-be developed areas Nationally the land-use literature ponrays compa c t development as more effici ent in its land-usc patterns and thus less land-consumptive Accord ingly, it often requires somewhat less development infrastructure. Compact development is also viewed as not limiting or restricting population or employment growth at th e county, regional. or state levels. (Burchell 1997a, A-ll BurcheU developed a series of quantitative model s rela t ing to land consum ption, road, tra nsit water/se w e r infrastructure, fiscal impacts. housing cost, and quality of life to examine the relative effects of alternative development patterns. Application of these models across the aforem e ntioned jurisd. ic tions indica ted compar able o rder -of-magnit ude findings. For instance, a shift away from sprawl to compact growth was projected by Burchell to reduce water/sewer utility infrastructure costs by 8 pe rcent in New J e r sey. 7 percent in Lexington 8 percen t in the D elaware Estuary, 14 percen t in Michigan, and 1 3 percent in South Carolina. Table 4 summarizes the array of findings from the various BurcbeU studies (1992 1997). Table 5 groups the effe cts of sprawl, some dozen in all, i nto five overall catego ries. The Berkeley effon employ s the California Urban Futures (CUF) model of the San Franc isco Bay Area to tabulat e land consumed under t hree sce narios: (a) "business as usual"; (b) "maximum environmental protection"; and (c) "'compact cities." These scenarios are differentiated, respec tively, by (a) not restrictin g development either within the city or within unincorporated areas; (b) applying a r.mge of environmental restrictions to both location s but not restricting growth per se; and (c) restricting growt h to acknowledge some env iro nmental limitation s and countywide minimum population proje ct i ons. The two laner alternatives sbow considerable overall land sav ings, panicularly sensitive savings relat ive to the business-as-usual s ce nario Total land saved in scenarios band c was 15,000 and 46,000 acres, respect ively. Scenari o b saved nearly 60,000 acres of prime agricultural land, 10,500 acres of wetlands and 3, 000 acre s of stee p sloped land ; Scenario c saved 29,000 acres of prime agricultural land 10,500 acres of wetlands, and 8 ,000 acres of steep-sloped lands (Landi s 1995). 19 STUDIED REACTIONS TO S PRA WL-LUTRAQ ( OREGON) AND CONCU RRE NCY ( FLORIDA ) In the lat e 1 980s and early 1990s, sprawl growth on the nonhwestem and south eastern coasts of the United States resulted in two different reactions--both supponed by so -ca lled "friends" organizations.

TM Com of organ i zation was the 1000 F rie11ds of Oregon, i n the second case, the 1000 Friends of Florida. In the early 1990s, growth in the Portland region was believed to hinge on the construction of a Western Bypass around the city. An alt ernative plan was soug h t to try to aceomrnodate growth without the need for more highways. Sam Seskin of Parsons Brinc k erho ff, leading a team of researchers i n the Land Use Tr.mspor tation Air Quality simulation ( LUTRAQ), compared the transponation impacts of a transit-oriented development (TO D) plan to the impacts of a preferred Bypass alternative. The LUTRAQ alternative sh ifted t h e location of 65% of new residential units and 78% of new jobs to locations within walking distance of ligbt rail or bus transit lines by reconfiguring expected development i nto a series of mixed-use centers. The alternative Ovrvie w/History show e d a reduct i on i n vehicle miles traveled and a reduction of the use of the automobile (Davis and Seskin 1 997). Ponland voters responded by approving a $1 billion rail line along which TOO wiU occur, and Seskin received an Ame rican Planning Association award for the research effon Subsequent analyses produced by Genevieve Giuliano, however, found only small gains associated with non automobile mode shares and very small reductions in vehicu lar travel. Equally distressing, the magnitude of i n vestment i n transit services needed to be quite large to achieve the result i ng changes in mode shares The LUTRAQ study uninten tionally demonstrated the limits of making large inves tments in transit t o influence travel patterns (Giuliano 1995b).

l n Aorida, meanwhile, the reaction to sprawl was to limit development if it could not be shown that sufficient public faciliti e s would be in place at the time that develop ment occurred (Aorida Growth Management A c t 1985). This procedure termed "concurrency," included both mandatory (transportation) and voluntary (schools) component s. At fi1St, those distant from tbe scene thought !hat the procedure was responsible for shutting down growth in the state. After !he dust from the housing recession of !he late 1980s settled, however, those originally opposed to concurrency reluctantly agreed !hat it had chann eled growth effec tively. I n t h e meantime. those who orig inally favored concurrency vehement ly opposed it because roads were being built and widened and new sc hools were being constructed (albe it at developer cost) too far from !he locus of existing development. Growth was slowed, but it also was accommodated in locations where it should not have been ( Mofson 1997) A T WHAT SCALE I S MEASUREMENT TO TAKE PLACE? URBAN FORM A N D TRANSPORTATION At about tbe same time !hat Burchell and Landis were looking at development form and itS effect on resource consumption, two other important considerations began to e m e rge Th e first was !he scal e at which transportation were bei n g viewed; the second was the effec t of transportation on urban form, and vice versa. lo other words, wnile attempting to define !he indicators of sprawl and more compact forms of development and their resulting impacts, it became apparent that one Deeded to specify at what l evel impactS were being measured individu al, community or societal. Almost all studie s to date have been undertaken with impacts specific to lhe Brooking Por.ou ECONoriflwe..ll 21 Overview/History community level. But Sam Seskin from Parson s Brinckerboff, and Terry Moore from ECONo rlhwest, began pursuing the issue of "full" costs of tran sportation, attempting to view the costS of transportation decisions at the individual and societal scales as well as at the communiry level. They determined, for instance, that although using an automobile was efficient at the individual and community scal es, it was expensive at a societal scale (air pollution). Although transit was efficient at individual and societal scales, it was expensive at a community seale (the cost to deliver transi t ) And wal king, a lthough efficient at co mmunity and societal sca les, was expensive at an individual scale (the cost of the individual's time) (Parsons Brinckerhoff 1996a; M oore and Thorsnes 1994). Seskin and Moore shifted lhe inquiry to issues of the impact of urban form on transportation, and vice versa. The urban form impacts o n transportation were much as expected. Se skin and Moore det ermined that sprawl developm en t could be served well only by the automobile; much more compact development led to transit solutions Mixed-use developmen t enabled walking and biking. Transportation impacts on urban form were not quite a mirror image of the first, however Significant use of the automobile led to unlimited spread development. Transit presence brought u sers who also neede d an automobile; mixed -use development promoted foot and bicycle use, but an automobile was still required. Land use can affect transportation mode and vice versa, but American society today remains heavily dependent upon the automobile (Parsons Brinckerboff and ECONorlhwest 1996).

CERVERO AND TRANSPORTATION ACCESSIBILITY MEASURES One of the most widely published academics in the field of transportation planning is Robert Cervero, from the University of California at Berkeley Ever since his first book, Suburban Gridlock, was published in 1986, Cervero has been solidly represented in the land use/transportation literature. His latest book, The Transit Metropolis ( 1998), will be released shortly. For the most part his work focuses on: (I) suburban congestion as we11 as measures for its relief (Cervero 1986, 1991 a); (2) the role of suburban activity centers as a lt ernatives to sprawl, and commuting patterns within these centers (Cervero 1989, 1991b, 1996); and (3) the feasibility of transit in suburban locations-i.e., the required density and implementat ion costs (Cervcro 1994a, J994b). Cervero s most interesting contributions from a sprawl perspective are two papers be co authored on suburban accessibility: (I) a 1996 paper co-authored by Kara Kockelman, entitled "Travel Demand and the 3Ds: Density, Diversity, and Design"; and (2) a 1997 paper co-authored by Timothy Rood and Bruce Appelyard, entitled ''Job Accessibility as a Performance Indicator: An Analysis of Trends and their Social Policy Implications in the Bay Area." In these papers, Cervero and his co11eagues show through factor and regression analyses the effect of current development patterns on employmen t accessibility. Th ey try to document, in other words, how well transportation serves employment m arkets. In the first article, Cervero finds that current sprawl development patterns have the largest impact on severely poor neighborhoods because they separate jobs from job seekers.

He upholds the views of the new urbanists-somew bat, because he shows that sensitive land design and building arrangements can reduce travel distances and alter modes of travel. THE BANK OF AMERICA STUDY: BUSI NESS EMBRACES THE ANTISPRA WL MOVEMENT In 1995, four groups-Bank of America, California Resources Agency, Greenbelt Alliance, and Low-Income Housing Fund-published a study on sprawl that quickly came to be known as the Bank of America Study. Those who champion land development alternatives to sprawl point to this study, the work of one of the private sector's most influential members, as a landmark. If the hanks finally realize that sprawl can no longer be tolerated, recognition of the impacts of differing land development patterns on society's resources has indeed hit the big time. The Bank of America study summarized changes in population, demographics, and employment that had taken place over the two decades prior to 1990. It also referenced a land-use pattern that had taken place during this same period of time and termed it "sprawl." Sprawl was characterized by decentralized employment centers and residential tracts TRANSIT COOPERATIVE RESEARCH PROGRAM (rCRP) H-10

ment pattern and an:hitecture and ask those surveyed to pick between the two. Often it is hoped by those who administer these surveys that the alternative develotr ment pa ttern will be chosen and, accord ingly, l ocalities will develop residential and residential areas in a differen t way (Ca lthorpe 1993). M ost of those who experie nce this exercise of choice op t for the alternative, which typically shows a denser, more traditional residential village center and less spread-out residential subdivisions and strip commercial developments (Nelessen 1 994 ). The results of most of the above categories of literature on consume r pref erence and sprawl indica t e that people feel comfortable with their cu rrent hous ing and its suburban locat io n but also think that sprawl has an ugly look and that suburbs are becoming increasingly congested. Whet her people would change their housing l)' pe (single-family), form (single-lot subdivision), or location (su burbs) to achieve a different "l ook" or "feel," o r to be free from co ngestion, rema ins an unans wered question AN UNUSUAL FINDING: THE CITY IS IMPORTANT TO T H E REG I ON ; THE US UAL F I NDING: PEOPLE DON'T CARE The United States has had a lovo-bate relations hi p with its cities for at least fifty years. Th i s has taken two forms. The first is inquiry into the continued importance of the central city; the second is whether or not people will choose to live and work there. In the mid-1990s, two anicles rekindled interest in, and attempted t o quantify the imponance of, the central cily to its surrounding area. One was written by Elliot Sclar and Walter Hook i n 1993, 'The Importance of Cities to the National Economy"; the other was written by Keith lhlanfeldt in 1995 and entitled ''The Importance of the Central City to the Regional and National Economy. At a lt'ltpn troo\inga lf'!ncbrholf ECONorthw.t 24 0e Mew{Hiakwy time when most scholars viewed the central cily's role in the region and nation as not critical and one of declining value, Sclar/Hook and lhlanfe l dt breathed new life into the debate on the role and future of the central cily w ith the following arguments: In most metro areas, the higher paying jobs are found in the central city. In the metro areas of the I 00 largest U.S. cities. half of suburban families had at least one worker employed in the central cil)'. Six1y-seven perc ent of suburban residents surrounding the 100 largest U.S. cities depend on the city for major medical care; 43 percent have a family membe r attendin g an insti tution of higher learn ing there. Cities provide low-cost housing for low wage workers employed in-and necessary for--the activitie s or suburbs. The overall appeal of a region is influenced by condition s prevailing within its ce ntral c ity. Sclar and Hooks argued that the United States subsid izes suburbs through homeownership income taX deductions and by federaUstat e cost-sharing of highway construction. Continued subsidization will cause increasing auto dependence, and a further channeling of most infrastructure expenditures to road building, at the expense of education operating costs According to the authors the United States ranks l owest among the seven most ind ustriali zed nati ons in percent of GNP that suppon s educa tion. lhlanfeldt finds that central cities possess certain "agglo meration economies" (the benefits of seale) that will sustain their primacy in a region. These include communications, labo r and producer concentrations Moreover, financial services such as investment banking, commercial banking, legal auditing, and actuarial services are provid ed primarily by ce ntral city firms to suburban markets TRANSIT COOPERATIVE RESEARCH PROGRAM (7CRPJ H.l 0

and in many cases to world markets. According to Thlanfeldt, these activities are not likely to be taken on by suburban firms, because few suburban firms have the appropriate scale to conduct them. The United States subsidizes suburbs through homeownership income tax deductions and by federal/state cost-sharing of highway construction. The second issue regarding urban areas is whether upwardly mobile households will continue to reside there In the 1970s, the United States experienced significant movement of jobs and residents to ex urban or rural areas. During this period of time non metropolitan areas were the locations of the fastest relative emp loyment and household growth (Stemlieb and Hughes 1983). During the 1980s there was stabilization, if not growth, of metro politan areas. Buoyed by significant immigration and a slowing of metropolitan to non-metropolitan out migration, metr opolitan areas were beginning to grow (Gordon, Richardson, and Yu 1997; Nelson et aL 1995, 1997). According to Peter Gordon, the latest Bureau of Economic Analysis (BEA) Regional Economic Information System (RBIS) data indicate that the trend is once again toward outer areas; indeed, over the l ast six years, outward metropolitan movement is almost as pronounced as it was during the 1970s. Gordon et al. finds that the one constant in all of this has been s tr ong suburban growth, with parallel rural growth tilting the scale to outward movement, and even stronger suburban growth with reduced declines of urban areas tilting the scale toward inward movement The consistency of the suburban component of this trend and renewed non-metropolitan growth (the outward movement) do not bode well for the future of the central city. Gordon and his colleagues conclude, citing additional Rutg:e.t 8rookitlg PorJOnl 81-lnekerhoH ECON

Regardless of methodology, the studies achieve their goal of representing farmland not merely as fiscally neutral but as fiscally positive. "Smart" comm unities should not want to lose this net revenue producer to other fonns of development (espec ially residential ), which would be more costly (AFT 1992b). Growing out of this new attention to farmland was the recognition that fanners, as owners of this land. were often opposed to growth managemen t (and thus pro-sprawl) and needed to be brought into the negotiation process. Otherwise, they would sell their land to developers before it could be acquired via public purchase or through some type of transfer of development rights. Farmers prevented passage of the original Matyland Growth Management Act and threatened to do the same to the New Jersey State Plan if their real estate interests could not be protected. In Matyland, it appeared that the farmers could not be assuaged, and the Growth Management Act1 failed In New Jersey, farmers were appeased at the eleventh hour with a promise from the New Jersey State Planning Commi ssion that their development rights would be purchase d at a price somewhere between crop and real estate value, and the planning statute passed. Randall Arendt. influenced by living in both walkable and planned open space communities in New Jersey as a child, and seeing these concepts implemented in 1 Maryland ultimately passed a diluted version of the original act and has adopted a vatiety or "sman gtowth" procedures. 26 England as an adul t. built upon Ian M cHarg's Design wirh Nature (1969) in an attempt to make current development patterns greener. In his latest books, Rural by Design ( I994b ), Conservalion Design for Subdivisions ( 1996), and Growing Greener (1997), he provides convincing evidence that open space adds to the value of surrounding real estate and tO the quality of life of those who live within i t Arendt sees the combination o f compact development and open space leading to interconnected networks of green space (Arendt 1994b) An area wide, interconnect ed greenway can extend open space and wildlife benefits to the larger region. Further, successful control of sprawl will retain the "traditional character" of communities (Arendt 1996). THE MECHANICS OF PAYI NG FOR SPRAWL: IMPA C T FEES, TAKINGS, AND PROPERTY RIGHTS In order to pay for sprawl and not impact current residents, local governments have turned to economists and land use anorneys to devise a system of assigning a share of new required public service infrastructure to new owners of developed property. These mechanisms are termed impact fees, developer exactions, or proffers and are based on the rationale of charging developm ent costs to those who have caused them. Impact fees are calculated by determining the specific costs that one new unit of residential development or 1,000 square feet of nonresidential development will cause in roads, water/sewer, public buildings (schools and municipal), and other capital infrastructure. Impact fees, developer charg es or whatever moniker they are known by, are currently the fastest-growing source of municipal revenues.

Nicholas has con.sttucted impact fee schedu les in numerous cou nties and municipal jurisdictions; both Nicholas and Nelson have signific an t academi c and prof essiona l publicat ions in this area The iss u e with impact fees specifically, and growth management strategies g enerally, is that t hese m echa nisms pre suppose government capacity to regul a t e land T his amounts to a t aking and thereby a ffec t s individual property rights Although m ost of these teclullque s have been upheld when they become overly aggnessiv e, they are subjec t to judicial review.

Tllese mech anisms are termed impact fees. This gets to what land-use attorneys describe as the black hole" of takings jurisprudence. U ntil recently, a severe t est of a taking has been applied. A land use regulation is a takin g if it: (I) does not substantially ad vance a legiti mate state interest ; or (2) denies an owner all economically viable usc of his or her p roperty. Post-1990, ther e appears to be an casing of this test that favors property own ers. C harles Siemon (Si emon 1997) Robert Freil ich (Freilich and Peshoff 1997). and Jerold Kayden ( Young 1995) are recurringly involved in litigation concerning these issues or in designing land -use regulations to avoid s uch litigation. Suburban dev e l o pment ordinan ces that require payment for costs or link "soci al" objective s t o the development of real property will be 27 t e sted by the couns. To pay for s praw l local governments have become quite inventive at bolh derivin g fee schedu les and in locating property owners to whom the costs can be assigned. M uch as other forms of payment for s prawl are drying up, if governments are not caref ul, so too w ill these mechanis m s S P RAW L'S CRITICS A N D THE NEW URBAN I STS In 1993, a study conducted for the Chesapeak e Bay Program defined sprawl as "residential development at a dens ity of less !han three dwelling units per acre" (CH2 M Hill 1993). This definition did not have a "locational component" and was a modification of a definition presented in an earlier draft i.e .. "developments having gross deve l opment densities of less than three or four dwelling units per acre or minimum lor sizes of at least one q uarter of an acre, and frequently of a t least one acre." T he latter defin ition had been criticized by Uri Avin (1993) for includin g properties with too high a density; it c ould be applied t o man y e x isting. c lose -in subdivisions in bolh Maryland and Virginia. On the other h and, in California. sprawl is curre n tly taking pl ace o n 9,000.squar e-foot lots; the upper l eve l density cutoff varies co nsider ably by region. Sprawl and more generally, suburbanization were co ndemned in a polemical book by James KunsUer ( 199 3). The title of the book, The Geography of Nowhere: The Rise and De c line of America's Man Made Landscape, conveys h is messag e The strident tone of th e message is reflected by the following statement: W e have become accus tomed to living in places wher e nothing relates to anything else. where disorder, uncon sciousness, and the absence of respect r eign unchec ked.

He presented a scheme for clustering housing and other improvements around transit stops at s pecified dens ities which co uld, in tum, be used to compute overall densities for ideal future metropolitan settlements.

MORE SPRAWL C RlTICS-"TRUSTS" AND OLD "FRIEN DS A critique of strip commercial development, and sprawl in general, penneates the current literature of the National Trust for Historic Preservation (NTHP ) and its leadership (NHTP 1993; Moe 1996). Richard Moe president of the National Trust, defines spraw l as 4poorly planned, land-consumptive, automobile-dependent developme.nt designed without regard to its surroundings." He identifi es two types: "sellscape" retail development fre quently spurred by major discount chains such a s Wai-Mart and K-Mart. oc-e. urring along major arteries and at highway inter changes; and ''spread out" residential development. usually consisting poimaoily o f sing le-family detached houses. located on the edges of existing communities or "leapfrogging" into previously undeveloped areas. (Moe 1996. 3) This view identifies commercial strip development as a manif estation of nonresidential sprawl. It also identifies low-d ensity single family subdivisions as a reside ntial sprawl type l n a later work, Moe and Caner Wilke (1997) indicate that sprawl is communities to be dysfunctional. Communiti es are either fighting for or los ing ratables because individual land uses are free to pick up and choose where they want to go in the metropolitan area. According to both authors, growth contro ls and the reus e of inner s uburban and urban areas offer the best chance s for successful land development. A much more comprehen s ive view of the components of sprawl is offered in Henry Richmond's 1995 book. Regionalism: Chicago as an Ameri ca n Region. Richmond's conceptuali zatio n of spraw l includes eight components: 19 I ) low residential density ; 2) unlimited outwar d extension of new development; 3) l eapfrog development; 4) spatia l segregation of different land uses; 5) decentralized land ownership; 6) primacy of automobile transportation; 7) fragmentation of governmental land use authority; and 8) disparity in the capacity of local govemm enL Com mercial strip development is a manifestation of nonresidential sprawl. Richmond, former director of I 000 Friends of Oregon and a panicipant in the LUTRAQ simulation SIUdy, offers a wide-ranging critique of sprawl and includes numerous carefully culled statistics supporting his allegations. Many of his critic isms also focus on the subject of his more current research-th e Chicago metropolitan area. His criticisms are the basis for his definition of sprawl. In defining sprawl, however, Richmond does not present specific alternative forms of growth, either conceptually or in terms of quantified analysis. I nstead, he pre sents a long agenda of specific poli cy actions lh

first took place in Washington DC, and was co-sponsored by the National Trust for Historic Preservation and The Brookings Institution. This conference brought all the nat ional actors on sprawl together in a debate format. Sprawl's good and bad attributes were debated before a national audience. This was the first appearance of the defenders of sprawl. Pet er Linneman from the University of Penn sylvania and P eter Gordon from USC proved to be strong advocates for the free. market meritS of continued suburbanilation, or sprawl. So successfu l was the conference in drawing national attention to the spraw l issue, as well as in drawing attention to the institutions that sponsored the conference, that the Lincoln Institute held derivative conference s in two locationsFlorida and California. Even though no debate was scheduled, again the issu e was raised : How bad is sp rawl ? Gordon, joined by colleague Genevieve Giuliano, provided a strong and cogent argument in favor of sprawl and presented findings c ontrary to the research of Seskin (LUTRAQ), Landis (California Futures Studies), Burchell (Rutgers Modeling Studies), and Down s (New Visions for Metropolitan America) The savings gleaned from LUTRAQ were described as minimal, and the landfmfrastructure sav ings of the California Futures and Rutgers studies were trivialized. Downs was also criticized for assigning causes of central city declin e to spraw l that could not be defended In I 996 and 1997, at the annual meetings of the Georgia Conservancy, sprawl was again the topic of consideration. Like the National Trust, the Georgia Conservancy shifted irs focus slightly from historic preservation and was making a major substantiv e thrust at curbing urban sprawl. These conferences, which again attracted national spokespersons on the 30 manifestations and costs of sprawl, were not a debate, but rather repres ented a summation on the ills of sprawl. The Atlanta region was growing at a rate of 55,000 jobs per year, and the econom y was in s uch a boom period that growth was flooding tbe arterials in and around the city. Sprawl needed to be contained, and the conferences were the beginning steps in an attempt to create a mood for regional growth managemenL However even though some sentiment for growth was apparent, the consensus was that political jurisdictions in Georgia were a long way from being able to implement, even on a regional scale the mo s t e l emental of growth management techniques (a growth bound ary). T H E S PRAWL DEBATE: EW ING VERSUS GORDON I N PRINT AND IN PER SON The debate over sprawl is brought front and center in two "poin t" and "counterpoint" articles in the Joumal of tire American Planning Association The point article by Peter G ordon and Harry W. Richardson (l997a) critiques the argumentS and evidence frequently presented in favor of compact development (i.e., energy. transportation, and infrastructu re efficienci es) and argues that the decentralized suburban pattern of devel o pment, in fact, offers many advantages, including reduced travel times an d lower housing costs, as well as higher cons umer satisfaction. In counterpoint, Reid Ewing ( 1997) makes a strong ease for the adverse effects of sprawl (as opposed to the benefits of compactness). Ewing point s to increased infrastruc ture cosrs, increasing travel distances, and significant amountS of developable and lost fragile lan ds as the adverse effects of sprawl TRANSIT COOPERAOVE RESEARCH PROGRAM (TCRP) H lO

The Cosh ol Sprowi-Revisitctl For the purposes of this review, the authors' respective definitions of terms bear note. For Ewing, sprawl is defined both by a series of three characzeriszics (J) leapfrog or scattered development; (2) commercial strip development; and (3) large expanses of low-density or single use developments -as well as by such indicators as low accessibility and Jack of functional open space (Ewing 1997). Gordon and Richardson do not specifically define sprawl (or compactness, for that matter). Instead, they reference various traits. Sprawl is alternatively denoted by Gordon and Richardson as low-d en sity, dispersed or decentralized development whereas compactness is associated with higher densities and a downtown or central-city spatial pattern versus a polycentric (or dispers ed ) spatial pattern (Gordon and Richardson 1997a, 95). Adverse effects of sprawl i11clude increased infrastructure costs, increasi11g travel dista11ces, a11d significant amou11ts of developable and lost fragile lands. Although the point-counterpoint authors address more than 15 different subjects in discussing sprawl and its alternatives, the can be grouped into five broad areas, as shown in Table 6. The deba t e moved from print to person in a forum held at the University of California-Berkeley in late November 1997. Both Ewing and Gordon had significantly increased the weaponry used t o support their individual positions. Ewing began the session with points of mutual agreement and spun out a longer listtban most expected. These included that ( 1) the market for transit was limited; (2) infrastructure costs were higher for sprawl development initially but could diminish over time with in fill; and (3) Rvtgtn Brookings POUOfll Brlnek rholf ECONortlw"''' 3 t Overview/Histo't automobile costs as a function of suburban residence were high, but few alternatives to this mode of travel and its costs existed. Ewing and Gordon continued to disagree about whether resource consumption (energy,land) differences under sprawl and compact development in light of national and global resources were sufficiently significant to cause concern, and whether the traffic consequences of sprawl (excessive travel and roadway congestion) could be argued away in terms of either current or future of resolution (higher trave l speeds, congestion pricing). The session was narrowly focused on primarily transportation issues and never reaJiy dealt with the social or quality-of-life of sprawl. CONTINUATION OF SPRAWL PRINT HOUSING POLICY DEBATE AND THE URBAN LAWYER SYMPOSIA One of the leading housing journals, Fannie Mae's Housing Policy and Debate, and a respected legal journal, 77le Urban l..Llwyer, both recently published symposia about sprawl. Several of the individual articles bear mentiorung, but an important fll'st point is that both housing and urban legal journals have come to recognize that suburban sprawl is an im portant topic for inclusion in their journals. This is significant. Both of the journals have had special issues on homelessness, exclusionary zoning, affordable housing, the economies of cities the spatial mismatch of the poor in cities and available jobs in suburbs, and so on. Neither journal strays far from housing and urban problems. T hus, implicit in the publication of the two special issues on sprawl is the notion that at least some component of spraw l impacts on housing issues and quality of TRANSIT COOPERATIVE RESEARCH PROGRAM {TCRP) /1.1 0

The Cotfs of Sprowi-Revisitec:l life. Sprawl does not onl y potentially cause excess resources to be expended in providing public infrastructure or, similarly, contr i bute to the loss of spec ial lands and habitats. Sprawl does not only chain user s to a single source of transpor tation for access to residential and employment opportunities. Sprawl has significant social and quality-of-life effects as well. In The Urban Lawyer compilation of articles Robert Freilich traces significant suburbanizing periods and carefully out their impacts on central cities. Spraw l, he notes, is the force that distills the city's economic base, and it is orchestrated by suburban land-use controls that p romo t e exclusion (Freilich and Pesho ff 1997) Charle s Siemon points to the very limited number of techn iques available to implement growth management and the difficulty of using them without encroaching upon property rights ( Siemon 1997). Suburban sprawl is an important topic for in housing and urban legal journals. In the Housing Policy Debate articles, Robert Lang points to the voracity of sprawl and terms it suburbanization that is thriving and will not be shelved. Lang further comments that it is not productive to refer to nonresidential sprawl as "edge cities," a very limited phenomenon whose time may be past. T o Lang, sprawl reflects market preference, and its direction is clear-a continuing ourward thrust from its urban core (Lang and Homburg 1997). William F ischel of Dartmouth also makes the point in the special issue of Housing Policy Debate that too much growth management may cause hou sing markets to diminish. If you continue to castigate sprawl, you may turn around and not find any growth (Fischel 1997). 33 Overview/History The upshot of this ongoing debate is that whereas at one time sprawl had only a solid line of inquiry detailing its costs, there is now a growing line o f inquiry detailing its benefits. If you continue to castigate sprawl, you may turn around and not find any growth. RESPONDING TO THE CHARGE: REGIONAL COOPERATION AND REGIONAL/STATEWIDE PLANNING A one-man crusade against factionalized government has been waged by Myron Ortield state representative for the City of Minneapol i s in the Minnesota House of Representatives. Orfield believes that the best way to control sprawl is to get local governments to cooperate in developing regional strategies, land-use policies, and regulatory mechanisms. In his hook Metropolitics, Orfield composes an aggressive regional strategy that links tax base sharing to affordable housing provision, farmland protection, and urban/inner-suburb redevelopment (Ortield 1 997). Orfield is a realist, however, and acknowledges that regional governments are not growing nationally but regional cooperation is. Currently, there is increased willingness to share selected municipal service delivery systems; there is virtually no interest in forming new regional governments (Petersen 1996). At another level, there is an ongoing effort to promote planning at state and regional levels and to coordinate planning with infrastructure provision. State plans and growth management initiatives have been successfully put in place for the entire states of Colorado, Florida, Georgia, Maine, Maryland, New Jersey, TRANSIT COOPERADVE RESEARCH PROGRAM (fCRP) H lO

The guru of statewide planning who has followed it for most of his career and has testified as an expert witness in most state house hearings, is John DeGrave of Florida Atlantic University. DeGrove i s also politically astute and realizes that even the most encompassing state plan or growth management act will either be voluntary for compliance by subunits of govern ment, or non-punitive for non-compliance by these same subunits.

For a decade, Porter has been a focal point of the lite rature on growth management. From State and Regional initiatives for Managing Development to Managing Growth in America's Communities (Porter 1992 ; Porter 1997}, Porter has been involved in implementing managed growth alternatives. This includes model regulatory and programmatic techniques and pairing these specific techniques with a particular growth management issue or problem. One of tbe most difficult tasks in land use is to effect meaningful region wide growth management. Porter has been involved with most of these growth management implementation efforts na t ionally. RESPONDING TO THE CHARGE: SUSTAINABLE DEVELOPMENT AND SMART GROWTH As yet another response for a new direction in land use, the sustainable development and smart growth movements have emerged in the United States. The U.S. sustainable developmem movement is a direct outflow of the World Congress on Sustainable Development held in Rio de Janeiro in 1992. This philosophy of development reflects a desire to "develop today without compromising available resources for future generations." For the most part, overburdened U.S. communities in the South, Southwest, and West have j ustified growth management prognuns under the guise of compliance with this norm (Krizek and Power 1996). Currently. twenty-one communities in the United States have adopted sustainable development ordinances that essentially limit growth to the degree that public facilities and services are in place to TRANSIT COOPERATIVE RESEARCH PROGRAM (TCRP/ H-10

Further, this Commission is deciding how improved transportation, education, and employment opportunities either add to or possibly detract from the goals of sustainability Precursors to current sustainability regulations were the 1970s' growth control efforts of California and Florida cities, and the concurrency requirement of the Aorida Growth Management Act of 1985. In the United States the President's Commission on Sustainable Development the U.S. Department of Commerce, the U .S. Economic Development Administration (EDA), and the U S.

The Com of Sprowi-Revisife-d li toroturo Synthosis 3 LITERATURE SYNTHESIS OF THE COSTS AND BENEFITS OF SPRAWL The purpose of this chapter is to divide the literature on sprawl into major fields and subfields of imp act in an effort to synthesize the most important studies in a systematic way. This effort identifies what researchers on the subject have considered and debated; what data have been used and how the data have been analyzed; and where the gaps in the state of knowledge are. The chapter is divided into two parts. The first is a synthesis of the literature as described above. The second is a summary of the literature, including: ( 1) topical coverage, databases, methodologies, and deficiencies; and (2) alleged negative and positive effects Thus, the synthesis of the literature in the first part of the chapter serves as a basis for statistical summaries of literature by typ e, database, methodology, and cat egory of i mp act in the second part of the cbapter.The statistical summary is one of the flf'St of its type. Although different literature citations could signal different emphases, it is believed that these cita tions and resulting emphases are correct in both direction and magnitude. 37 ANALYSIS OF THE LITERATURE A search of the literature reveals that various commentators have attributed more than two dozen negative and more than one dozen positive impacts to sprawl. These impacts are set forth in Table 7. The li s t is not a scientific tax onomy; it does not include all the alleged effects of sprawl. Rather, in the judgment of those reviewing the li t erature, i t in cludes some of the most s i gnificant i mpacts. F urther, not all of the allegations can he substantiated; nor are they of equal importance. However, this inventory presents a comprehensive set of allegations based on the relevant literature summarized here. The allegations have been classified into five substantive categories: I) public-private capital and operating costs; 2) transportation and trave l costs; TRANSIT COOPERATIVE RESEARCH PROGRAM (TCRPJ /1.10

3) land and natural habitat preservation; 4) quality of l ife; and 5) social issues. Each of the alleged negative and positive impacts found in the literature search under these five substantive groupings is examined in depth following a common presentation format as follows: I) Topic. What is the specific subject matter of the alleged cost or benefit? 2) Allegation/Basis. Synopsis of the alleged cost or benefi t and the basis or logic of the supposed effect. 3) Literature Symhesis P ertinent studies on the allegation are cited, either s upporting or rebutting it. The presentation o f the literature synthesis is accomplished using both text and a matrix. The matrix distinguishes: a) Whether or not the alleged factual condition exists under conditions of sprawl (or more generally whether development pattern affects the item in question). b) Whether or not the alleged factual condition if it exists -has been significantly linked to sprawl (i.e., to development pattern). For example, one allegation is that "sprawl generates more vehicle miles of travel than higher-density forms of development." This literature synthesis first notes whether there is, in fact, agreement among observers who comment on this subject. (There appears to be general agreement in this regard.) The next observation addresses the question of whether there is agreement in the literature that the presence of greater vehicle miles of travel in low-density settlements is significantly related to sprawl. (There is again, general agreement on the second count.) For simplification these judgm ents are shown in the form of a matrix: 39 s' A$:1-1 "- X exitf hit mongty linkd IO X -'' An "x" is placed in the matrix cell that contains th e appropriate answer to the question on that line This matrix is not a rigorous measuring instrument. It could have been produced in a variety of ways. Even as currently structured, there is not always consensus among reviewers on how to "'score'' an item-i. e whether there is "general agreement" or "some agreement" in the literature. For that matter, there is not always consensus on how convincing the literature is i n its relationship of development impacts to sprawl. PUBUC AND PRIVATE CAPITAL A N D OPERATING COSTS I.A. Sprawl's Alleged Negative Impacts I.A.l. Higher Infrastructure Costs Allegation/Basis ltifrastructure of a wide scope-e.g local and regional roads, water and sewer systems, and schools-is more expensive under sprawl than under compact devewpment. This allegation alludes to i nfrastruct ure that is primarily public (i.e., state, county, or local government roads; public utility systems; and public schools) and occasionally private (i.e. privately owned utility systems and subdivision-level roads that are not dedicated to the public sector).

The effec.t of sprawl on the cost of infrastructure allegedly occurs for several reasons. At sprawl's lower development densities, various components of infrastructure that are linearly related (i.e., sidewalks, curbs, subdivision-level roadways, and water and sewer mains) serve a lesser increment of development than these components of infrastructure would serve at higher levels of density. The segregation of land uses associated with sprawl further increases infr a structure costs. Segregation of land uses by residential and nonresidential types often means that parallel infras t ructure systems have to be pro vided to individual residential and nonresidential locations Further, sprawl's leapfrog development, which locates growth away from eltisting development, does not capitalize on pockets of surplus infrastructure capacity that may already be present in and around existing development. Finally, fragmented governance, a seemingly natural accompaniment to sprawl, otlen leads to duplicative city balls police stations, courts, fire houses, schools, water/sewer treatment facilities, and so on. Literature Synthesis As shown earlier in Table I. The Costs of Sprawl (RERC 1974) found tha t cap ital costs per unit were higher in the "low diversity sprawl" and "sprawl mix" neighborhood prototypes than they were in the "planned mix" or "high-density planned mix" prototypes. The Costs of Sprawl also found that capital expenses per unit were higher in detached housing (more pronounced under sprawl) than they were in attached housing (more pronounced under compact development) The first finding of The Costs of Sprawl, although crit icized, has basically stood the test of time (Altshuler 40 literature Synthem 1977); the second finding proved to be the undoing of the study (Windsor 1979). Frank (1989) reanalyzed (using current cost numbers) several studies conducted between the 1950s and the 1980s that examined relationships between land use and infrastructure costs (including The Costs of Sprawl). Accounting for the limitations of The Costs of Sprawl study, he concluded that infrastructure costs were highest in situations of low density and for development located a considera ble distance from centralized public services (conditions of sprawl). In frastructure costs were lowest in situations of higher density and for development that was centrally and/or contiguously located (conditions of compact development). Duncan (I 989) analyzed the infrastructure costs of multiple Florida residential and nonresidential developments with varying patterns of development. Costs were higher for those with sprawl characteristics than they were for those with compact develo pment characteristics (see Table 8). Infrastructure costs were llighest in situations of low density and for development located a considerable distance from centralized public services. The longest-run modeling of infrastructure costs under different development sce nario s was performed by Burchell (1992 1997) in New Jersey and in other locations. The infrastructur e models applied by Burchell relate develo pment density and housing type to the demand f or local/state roads and water/sewer infrastructure. The studies found that the amount of land consumed for development was directly related to lane-miles of road required for two-lane (local) and four-lane (state) roads. Thus, densiry of development was found to be inversely related to lane-miles TRANSIT COOPERATIVE RESEARCH PROGRAM (TCRP) H-10

The findings were basically similar in order of magnilude across most of the other locations analyzed by Burchell (Burchell and Listokin 1995a) (see earlier Tables 3 and 4). The findings were also comparable to those arrived at by Frank (1989) and Duncan (1989) in their studies (see Table 9 below). Other relevant research indicating higher infrastructure costs under co nditions of s prawl includes Archer ( 1973) and Duensing ( 1977). Base data on infrastructure and its costs not related to development pattern, such as average capital outlays per single-family house or costs per linear foot of roadway, are provided by FACIR (1986), Fod or (1995), Nelson (1988), Nichols eta!.

The above body of research which reflects, in part an approach dating back to Tile Costs of Sprawl. bas been criticized on several counts by Altshuler (1977) and Altshuler and Gomez-Ibanez (1993) for the following reasons : I ) The higher infrastructure costs found in instances of lower versu s higher density ( i.e . sprawl versus compact development) are not meaningful because the hou sing units and their attendant scale found under the different developm ent alternativ es (i.e .. more detached housing under sprawl and more attached housing under compacl development ) are not comparable. 2) The higher infrastrucwre costs attributed to sprawl due to its leapfrog patterns will essentially be neutralized as areas that were initially passed ove r are ultimately devel oped. The next wave of growth will capitalize on the infrastructure 10 place. Thus, the higher initial cost will be recouped.

The Cosfs of eventual need and will ultimately be l ower the more rapidly that ioftll tak es place'' (Altshu le r and GomezIbanez 1993, 72 -73) 3) The higher infrastructure costs (under sprawl) attributed to the distance of development from central facilities does not consider potential economies of scale that could be realized in regionalized, oversized trunk lines or similarly located water/sewer treatment plants (Altshuler and Gomez-Ibanez 1 993, 73). In other words, the added "cos t s of distance" because feeder lines are longer under sprawl are not significan t if the feeder lines are attached to regionally located (and oversized) trunk lines and water/sewer p l ants. Holding aside the above criticisms, at least one researeber, Richard Peiser, finds the cost difference in infrastructure between sprawl and compact devel opment patterns to be quite slighl Peiser (1984) examined infrastructure co sts for new residential devel opmen t in two Texas "prototype" communities one planned the other unp l anned. The planned and unplanned developments were located on 7 ,500-acrc sites in Houston. The planned community was designed to accommodate a population of about 80,000 residents in 26,500 dwelling units and a workforce of72,000 in 24 million square feet of office and industrial space The development was largely self-contained and near existing development in the form of a large center The unplanned development was located in a primary growth corridor at the urban fringe, typical of Houston's sprawl pattern (100to 500 -acre subdivisions, strip malls, and s h opping centers). The Houston develop m ent was designed to accommodate about the same number of residents (80,000) and workers (72,000) as the planned development. In Peiser's model. the difference in capital expenses for the planned and unp lanned scenarios was about 5 percent in favor of the planned development. The fmding in the Peiser study that contradicts other findings in the field was the inclusion in overall planned development infrastructure savings of higher road costs associated with planned as opposed to u nplanned development (Table 10).

In sum, although there is general agreement that dev e lopment density is linked to infrastructure costs, there is less agreement about the interrelationship between sprawl (as a less carefully defined development form) and infrastructure costs.

Lite rature Syn t hesis Openlliog costs are those costs that accrue on a day-to-day basis and form the annual expenses of local government. These include public w orkers' sa laries and benefits; normal expenditures for supplies repa irs, and replaeement i tems; and debt service for capital facilities purchased or contracted for at the local government level (municipal and county). The litenl!Ure is rich with descriptions of variations in local (county and municipal) costs as a function of jurisdiction size, wealth, growth rate, and density of development. Generally speaking, per capita local costs are "U" shaped as a function of 44 population size..-Le., they are e x pensive for ju .risd. ictions with populations under 2,500 and over 50,000, with points of most efficiency in those locations where the population is between 10,000 and 25,000. Schoo l district per pupil costs increase with school district size. Districts with more than 3,000 pupils spend 20 to 30 percent more per pupil than districts of fewer than 1 ,000 pupils; districts of 1,000-3,000 pupils spend 10 percent more than districts of fewer than 1,000 pupils (Stemlieb and BurcbeU 1977; Burchell and 1996). Both local (municipal and county) public service costs per c a p ita and school dis trict public service cost s per pupil also vary directly with the wealth of the jurisdiction. The citizens of wealthier jurisdictions demand greater qualities and quantities of local and educational public services and are willing to pay for them (Burchell and Listoldn 1996). co m ........ .,_.

The of Sprowi-RoviJ;fed per capita and per pupil costs (Ladd 1992 ). Two caveats are noteworthy, however. First, comparisons almost always are made between suburban and urban-level densities and rarely between densities tha t reflect more-versus less intense suburban development. Second, none of the analyses performed to date standardize the quality or quantity of public services delivered (Altshuler and Gomez-Ibanez 1993). Thus, buried in the above fmdings is the fact that public services tha t are delivered in very large and dense local (municipal and county) j urisdictions are more complex and more individualized than those delivered in smaller, more sparsely populated jurisdictions. Foot patrol or rwo-person automobile police patrol takes the place of one-person automobile police patrol; full-time paid frre department employees take the place of v olunteers; and signifi cant numbers of special education teachers must be hired instead of contracting out special education services. AU these examples point to the service differences that complicate comparison of costs in more intensely populated versus less intensely populated jurisdictions Local government costs nationally average about $700 per capita; school district costs average about $7,000 per pupil (Census ojGovemments 1992). Of the former, about 60 percent goes toward salaries and benefits, 35 percent toward other expenses, and 5 percent toward capital purposes. Of the latter, 70 percent goes toward salary and benefits 20 percent toward other expenses and lO percent toward capital purposes. Compact or managed growth, the opposite of sprawl development, may encourage more regionalism in sebool systems and more sharing of non-police loca l public resources. It also reduces the 45 amount oflocal roads and water/sewer utility lines and hook-ups that are constructed and paid for by local debt service and maintained aod paid for out of annual operating budgets. Burchell in his analysis of the growth alternatives in the Impact Assessment of the New Jersey State Development and Redevelopmenr Plan, found that combined municipal and school district operational cost s could be reduced by 2 percent annually under planned (compact) growth, as opposed to tr end (sprawl) growth (Burchelll992a). Although the percentage seems small, the savings occur annually; they are not a one-time windfall, and the savings could potentially be applied nationally to local budgets that sum to $175 billion per year, and to school distri .ct budgets that sum nationally to $500 billion annually. Service differences complicate the comparison of costs in more intensely populated versus less intensely populated jurisdictions. I.n similar type studies in the Delaware Estuary, and in the state of Michigan, municipal costs were found to be S-6 percent less annually under compact growth scenarios than they were under spraw I development.

significant decreases in density to preserve lands a t the periphery, overal l residential and nonresidential development costs will be approximately 10 percent less per unit or per 1,000 square feet. Somewhat lesser savings (68%) emerged from studies conducted in Lexington, Kentucky (Burchell and Listokin 1994b), the Delaware E stuary (Burchell and Moskowitz 1995), and the state of Michigan (Burchell 1997a). O t her studies of residential development have produced essentially par.Ulel findings on tbe effects of increased lot and structure size on housing costs. Downs (1973), Schafer (1975), Seidel (1978), and others have found that large lot zoning and minimum building size increase the costs of new housing This same type of analysis applied to nonresidential development although not often l ooked at hy researchers in tbe field bas produced similar findings (Burchell 19921997). Some researchers have found that large lot sing l e-family zoning and minimum building sizes are associated w ith sprawl deve l opment. Smaller lot sizes (zero lot line) and different types and intensities of development (single-family attached and multifamily) are associated with compact development (Avin 1993; CH2M Hill 1993). Linking the above two sets of findings the savings noted by housing type should then extend to these two polar development fom1s. One cannot assume however, that housing preference changes will accompany deve l opment pattern shifts. In other words, if compact development is opted for, and denser foffilS of housing comprise this type of development, it cannot be assumed that market preferences will correspondingly shift and families previously occupying l ess dense types of housing under sprawl will 47 opt for the more intense development forms under compact development Further, if there is a crossover between housing types, one must carry the occupancy profile of tbe former to the new type of housing unit Otherwise, false conclusions could be drawn with regard to development cost savings associated with the often smaller and less intensely occupied housing of compact Large-lot single-family zoning and minimum building sizes are associated with sprawl development. development, and with the annual fiseal impact savings resul t ing from this development form. A critical error was discovered by Windsor in his review of The Costs of Sprawl (Windsor 1979). According to Windsor, The Costs of Sprawl study failed to account for the fact that the characteristics of new townhouse occupants who switched from detached single-fami l y occupancy (if they could be assumed to do so) woul d be closer to the characteristics of occupants of the units that they had left than to the characteristics of the occupants of units similar to their new housing. This lack of realization led to the erroneous conclusion that compact deve l opment (containing a larger percentage of townhouses) was less expensive to service than sprawl development (containing a larger percentage of single-family homes ), when the same households that occupied the former would likely be t he ones moving to the latter.

I.A.4. More A d ve r se Publ ic Fiscal Impacts A llegation/Basis Sprawl generates more adverse fiscal impacts than compact development because public operating costs are significantly higlu:r and residential uses and artendant revenues d o not compensate for these costs. Further, fragmented govemmenJS compete for land uses according to these land uses fiscal superiority Most "good" (from a local fiscal impact perspective ) economic uses have been withdrawn from central cities and transp lant ed to suburban juris dictions. Since there are not enoug h "good" land uses to go around, only the wealthiest jurisdictions truly benefit fiScally from these land uses. Literature Synthesis In analyzing the impa cts of land uses, the notion that some types of land uses are better fiscally than others has become widely accepted. Nonresidential land uses, for the most part, have been shown to be more profitable than residential uses, and most standard forms of residential land uses less profitable (see Table I I ). Further within the nonresidential and residential sectors, varying degrees of advantage and disadvantage exist. Some land uses produce more revenues than costs; if service levels arc maintained at the same level after d evelopment. taxes could be decrea.scd. The reverse i s also true. In some cases, costs exceed revenues and, all things being equal taxes might have to be increased (Burchell and L istokin 1994a). Position on the fiscal impact hierarchy depends on the type of unit (the size or intensity of use) within both residential and nonresidential classifications. F iscal literature Synl'hesi.s position also depends on the service district in wbich impact is being viewed. Often. for instance, a small condominium or age restricted housing unit may be or have a slightly positive or negative impact on the municipal service jurisdiction, yet both may be very positive fiscal ratables in the school dis trict. On the other hand, larger townhouses may be just below break even in the school district yet significantly negative in the municipal jurisdiction Fiscal impacts and observed differences under sprawl versus compact growth are dependent upon two different influences from development pallems The tirst is the ability of the de velopment pauem to influence type of development. To the degree that dwelling type can be changed by compact development in sub-state seuings. the demographics and consequently,the public service costs of development will change The second is the ability of the de'elopment The Ftscallmpacl of Growt h Unplanned growth is believed to result in greater costs to municipalities.

pattern to influence the intensity of development and geographic spread of new neighborhoods. If compact development can provide tighter development patterns, infrastructure provision will be l ess. So too will the annu a l debt service on capita l costs for roads, water/sewer lines, and so on, as well as the annual costs of maintenance associated with these new facilities The location where d e velopment takes place is also an important factor If located near existing development, excess service capacity may be drawn upon. If development is skipped over, public service infrastructure will almost always have to be provided at costs greater than if existing facilities were extended. If development is hJcated near existing development, excess service capacity may be drawn upon. Burchell s Impact Assessment of the New Jersey Stare Development and Redevelopmelll Plan (Burchell 1992a) employed a fiscal model to view the effects of trend versus planned development. The Rutgers fiscal impact model estimated the number of people, employees, and students that were generated under each of the development scenarios and projected th eir future costs and revenues to host public service jurisdictions Although at the regional and state levels population and employment projec t ions did not vary be t ween al t ernatives, at the municipal leve l the differences were significant. In the compact development case, urban communities w i th slack service capacity received more growth than rural areas with lesser amounts of p u blic service infrastructure The reduced infrastructure provision and potential l y reduced annual maintenance on this infrastructure led to diminished fiscal impacts for this alternative. 50 literature Synthesis Burchell s study in New Jersey found that: By containing population and jobs in already developed areas and by creating or expanding centers in newly developing areas, the State Plan offers an annual $112 million (or 2 percent] fiscal advantage to municipali t ies. This advantage reflects the ability under plan to draw on usable excess operating capacity in already developed areas as we ll as efficiencies of service delivery For i nstance, fewer lane miles of local roads will have to be built under plan, t hus saving municipal public works maintenance and debt service costs. Public school distric t s will realize a $286 million {or 2 percent! annual financial advantage under the State Plan, again a reflection of drawing on usable excess publ i c school operating capacity and other service and fiscal efficiencies realized due to the redirection of pop u lation u n de r the plan alternative Thus, municipal and school district provider s of public serv i ces could be ahead fiscally by close to $400 million annually under plan compared to trend while meeting similar population demands for public services. Under trend the s t ate's school districts will have to provide 288 .000 net pupil space s to the year 2010 (365,000 gross need les.' 77,000 usable excess space s); for plan, t he net need is lower at 278,000 pupi l spaces based on exc e ss space available in cen tr al cities Overall. if new s pace had to be built to accommodate net new stude nts, costs of n e w school facilities would be approximately $5.3 billion under trend and $5 1 billion under plan. Thus, $200 million (or approximately 3 percent) is potentially saved due to more excess capacity in closer -in areas being drawn upon by plan as opposed TRANSIT COOPERATIVE RESEARCH PROGRAM (rCRP) 11-10

Tltc Costs ol Sprowi-R.-visited meeting these demands increase with high er densities (compact development). Literature Synthesis Gordon and Richardson express this argument. citing the research of Ladd: Ladd (1992) argued that except within a range of v ery low densit ies. per capita p u blic service costs for traffic management, waste collection and disposal, and crime control. increase with higher densities. (Gordon and Richardson 1997a, 99) Again, this is the type of research that has not standardized for the quality and quantity o f public services delivered in jurisdictions of varying densities. Noneth ele ss, the abov e research indicates that without taking into account what serv i ces are delivered or who de livers them in a service district-operating costs, wha t ev e r they are comprised of appear to be less in jurisdictions of low dens ity than in jurisdictions of high dens ity. Operating costs appear to be. less in jurisdictions of low density than In jurisdictions of high density. However, comparisons of operating costs are usually made between locations of rural-suburban (I to 3 units per acre) density and those of urban density (16 to 30 or more units per acre) These studies may well be measuring the differences in range and complexity of public services delivered in densely populated urban areas versus rural-suburban areas, where the public services de li vered are very limited and much simpler (See also Negative Impacts-Higher Public Operating Costs).

Various fonns o f growth control limit housing production and drive up the costs of ho u sing. Literature Synthesis Does the overlay of regulations inherent in managed growth drive up the cost of housing? A number of studies reveal that in the imm ediat e area where growth restri c tions exist, housing prices increase (Fischel 1990). Schwartz, Hansen, and Green ( 198 I) followed the e ffec ts over time of the Petaluma (California) Plan which severely limited building permits, favoring dwellings w i th costly design features and developer-provided amenities and services to the community. Using a statistical (i.e., hedonic) pric ing technique, the authors compared tbe pnce of a standard bundle of housing characteristics to the corresponding price in nearby Santa Rosa, which had not adopted growth controls during the period. The authors found that after several years, Petaluma's housing prices had risen 8 percent above those of Santa Rosa. TRANSIT COOPERATIVE RESEARCH P ROGRAM ( TCRP) fi.IO

PAGE 60

Schwartz, Zorn, and Hansen (1989) did a similar study of the growth controls in Davis. California, comparing house prices in Davis to those in a sample of other Sacramento suburbs. They found that growth controls caused house prices in Davis to be nine percent higher in 1980 than they would have been withou t them. In Petaluma (Schwartz, Hansen, and Green 1981) and in Davis (Schwartz, Zorn, and Hansen 1989), the effects on the housing stock affordable to lowand moderate-income households relative to control areas were also monitored. In Petaluma, the authors found that the percentage of the housing stock that was affordable to low-and moderate-income household s dropped significantly below that of a control group (Fisch el 1990). In Davis on the other hand, growth controls required those who received build ing permits to construct some units earmarked for low-income occupants Thus the limited growth that did occur in Davis contained both low-income and high-income housing According to Fischel ( 1 990), however, an unanticipated offset t o this apparent success occurred: the existin g housing in Davis increased not only in price but in quality. Fischel's in terpreta tion of this outcome was that older housing was filtering up rather than down. Where growth is controlled as opposed to m4naged, housing costs are higher. Katz and Rosen (1987) analyzed 1 600 sales transactions of single-family houses during 1979 in 64 communities in tbe San Francisco Bay Area. O f these trans actions, 179 involved houses located in communities where a building permit moratorium or binding rationing system bad been recently, or was currently, in effect According to Fisch e l (1990), this 53 literolvre Synfile,is s t udy is particularly valuable since, unlike the o t her California studies, it did not focus on just a single community. The authors found that the price of houses sold in the growth -controlled communities was higher than the price of houses sol d in other commun i ties Where growth is controlled as opposed to managed. housing costs are higher.

Fosters Efficient Development of "Leapfrogged" Areas Allegation/Bas i s .,., Sprawl fosters efficient infi/1 development. Sprawl p e rmits appropriate, relatively high-density devel opment of still vacant close-in sites late in the development period of a metropolitan area, without hav i ng either to demolish existing on those sites at great cost, or to expend public funds buying such sites in advance and reserving them for later development. The "leapfrogging" aspect of sprawl leaves sizable tracts of land vacant and undeveloped Parcels remain vacant long after the wave of current growth has passed them by. These parcels can be developed later as "infill" sites at relatively high densities, which are more appropriate to their more central locat i ons. This process of deferred development is more efficient than first developing all peripheral land at low densities, and then tearing down the existing structures when the development marke t reflecting the preferences of TRANSIT COOPERATIVE RESEARCH PROGRAM (TCRP) /1.10 "'

suucture occupants, shifts to higher densities. Literature Synthesi s This allegation is considered by Peiser ( 1984) and is also discussed by Alts huler and Gomez-lbanct ( 1993). But it is often a highly neglected component of the analysis of infrastructure costs related to sprawl. Just as there are those who call for full costing methods to expand and account for the costs of sprawl to tbe private sector and to society as a whole, there are also those who believe that the second ary benefits of sprawl (i.e its lagged inftll economies) must be adequately tabulated in any account ing scheme related to development altemat i ves. Those land that a r e skipped over and initially not u std, become r easonably inexpensive to access and service seco n darily.

miles of travel increased by 1 9 percent between 1983 and 1990, and vehicle miles of travel (VMT) increased at the even faster rate of37 percent. Ray et al. ( 1994 ) found that the number and length of vehicle trips were increasing at an accelerating rate between 1977 and 1990. Sprawl, creates the longer travel distances and increases dependence on the automobile, is a major source of increased vehicle use. The quest io n is what proportion o f the growth in VMT is due to spraw l versus other factors. such as a higher rate of women participating in the workforce, the baby boom generation being a t the peak driving years. or rising incomes that allow every licensed driver in a household to own a car. Thnee factors have contribut ed about equally to the growth in VMT --<:hanging demographics, growing dependence on the automobile, and longer travel distances (Dunphy et al. 1997). Thus, sprawl which creates the longer travel distances and increases dependence on the automobile, is a major source of increased vehicle use. Numerous s tudies have linked lower vehicle miles of travel with more compact mixed-use developments. In a 1990 analysis of the San Francisco Bay area and a 1994 study of 28 California communities, Holtzc law found tha t residents of the denser neighborhoods drove fewer miles per year In a second study, where Holtzclaw (1994) controlled for the levels of transit service and vehicle ownership, a doubling of residential densities was associated with 16 percent fewer vehicle miles of travel. Other research by Harvey (1990), 1000 Friends of Oregon (1996), and t he Urban Land Ins titu te (Dunphy et al. 1997) confum 55 that as densit i es increase per capita vehicle miles of travel decline The interspersing of residents, employment, shopping, and other functions can also reduce VMT, by allowing shorter trips and the use of non vehicle modes. An empirical analysis by Frank and Pivo (1994) in the Puget Sound region and a simulation of the Trenton region undertaken in central New Jersey by the Middlesex. Somerset, Mercer Regional Council ( 1990 ) show that greater land-use mixes (with a higher jobs-housing balance) decrease trip distances and automobile mode shares. 10.6 11.6 36.J 11.2 19.7 20.7 HJ.7 33.6 20 commule length 36. 5 percent from 1985 to 1995; the t.rend is continuing.

Out" scenario with new development continuing at current typeS and densities with a "Growing Up" scenario that kept all growth within the existing urban growth boundary by reducing lot si1..es and introducing more multifamily housing. Average daily VMT was estimated to be 15 percent higher in the "Growing Out" scenario than in "Growing Up." Gordon and Ri chardson ( 1997a), however, do not agree that VMT would be reduced by more compact develo pment. They contend that market forces embodied in sprawl may ultimately result in less VMT as households and businesses locate near one another. They further argue, based on Crane's (1996) theoretical analysis of travel on the grid street networks of nco-traditional development. that this nco-traditional, or compact. type of development may produce more VMT due to the ease of automobile travel. But Ewing ( 1997) points out that the demand for activities is relatively inel astic and residents of more compact, neotraditional developments arc unlikely to drive more simply because of better street design. A preponderance of evidence contradicts Gordon and Richardson's claim that sprawl is not a factor contributing to increased VMT. Market forces embodied in sprawl may ultimately result in less VMT as households and busi n esses locate near one another.

Longer Travel Times A llegation/Basis Sprawl r eq uires that more rime be spent traveling than do more compa ct forms of development. The greater dispersion of activities in sprawl makes it neces sary to spend more time traveling between activities than in more compact. mixeduse areas where trips are shorter and can serve mul tiple purposes. Workers in mixed use settings can eat lunch or run errands at noon without using significant amounts of time for travel. Residents of compact neighborhoods can meet many of their needs at community shopping centers. Literature Synthe s i s The evidence is mixed on the effects of sprawl on total uavel times Ewing ( 1995c) has shown that total travel time varies with regional accessibility His Florida study found that residents of areas with high levels of access to a mix of uses including jobs, schools, shopping, and other servic es spent up to 40 minutes less per day in vehicular travel than residents io less accessible neighbor hoods Time was saved by linking trips into tours and by making shorter trips. Dunphy et al. ( 1997), on the other hand, also report that according to surveys. people are willing to accept longer travel times to work and shopping in order to have the quality of housing they desire. Thus, the segregation of l and uses and l ess expensive land at the periphery two characteristics of sprawl--<;art increase travel times, whereas mixed-use developments, wherever they are located appear to decrease travel times Others contend that travel times do not increase with sprawl because more trips are made by the automobile, the fastest mode of travel, and peopl e and activities IRANSrr COOPERATIVE RESeARCH PROGRAM (TCRP) Il-l 0

adjust over time to keep travel times relatively constant ( Gordon and Richardson 1997a). A s tudy by the European Conference of Ministers of Transport (1994) found that people in four c i ties wit h very different urban struct ures (Wismar, West Germany; Delft, The Netherlands; Zurich, Switzerland; and Perth Ausualia) made about the same number of trips and spent about the same amount of time traveling even though modal shares differed significantly. The average time s pent uaveling ranged only from 62 t o 69 minutes. Purvis (1994) reported that travel time budgets remained fairly constant in the San Franc isco Bay Area between 1960 and 1990.ln the latest survey. the number of trips per person declined, but travel times remained cons tant because of the longer duration of trips Purvis says the results are comparable to those in other metropolitan areas and consistent with the uavel time budget studies of the 1970s and 1980s. Reside n t s of a r eas with high levels of access t o a mix of uses including jobs, schools, s hop ping, and other spe.nt 40 minutes less per day m vehu:ular travel than residents of the least accessible neighborhood s Overall, the evidence is not clear about the relationship betw een spraw l and households' total travel times. On the on e hand, some metropolitan-wide data suggest that people have fairly constant uavel time budgets On the other hand, a finer level of analy sis indicates that the outward expansion of urban areas and the segregation of uses has boosted the amount of time some households spend uaveling to their daily activities. 57 Suburban residents spend more time commuting t o ,.,..orJc: than central ciry resident$.

Literature Synthesis An extensive literature shows that when development is more compact and land uses are mixed, transit and walking mode shares rise and vehicle mode shares decline. Research for TCRP H-1 (Parsons Brinckerhoff 1996c) shows that residents of denser more mixed-used neighborhoods were more likely to go by transit or to walk for all types of trips. Another part of this project showed that higher residential densities in rail corridors and higher employment densities in the CBDs increase rail use (Parsons Brinckerhoff 1996b). Empirical research by Cervero (1986, 1989 ), Cervero and Gorham (1995), Dunphy and Fisher (1 994), Frank and Pivo (1994), Handy (1992, 1995), Kenworthy and Newman (1993), and Kitamura et al. (1994) confirm that higher density, more pedestrian-friendly neighborhoods and employment centers support travel by non-automotive modes. Kenworthy and Newman compared the rates of growth in central, inner, and outer neighborhoods in the United States (where those with higher incomes move to the edge) and Australia (where those with lower incomes move to the edge) and found that automobile travel was growing rapidly in the outer areas of cities in both counties. Their conclusion: It is clear that the level of automobile usc is not simply a matter of how wealthy people are but is also heavily dependent on the stru ctur e of the city and whether transport options are available other than the automobile. Thus as cities become more dispersed and lower in density towards the edges, the level of compul sory automobile use rises mark edly, regardless of income level.

In add ition, more trips are made b y au tomobile, especially the sing le-occupant vehicle, the fastest and most direct mode of trav el. 61 Literature Synthesis Gordon and Ric h ardson (1997a) argue that b u sines ses follow people t o the s uburbs. thereby making trip s to work s horter as measured in time. not in di s t ance. The correct ion is not in s tantaneous but over t ime. businesses move to suburb an locations near w o rkers. creating a new eq uilibrium with shorter wor k times. Although some people have longer trips. especially during the adjustment period. on average, commuting times h av e not in creased due t o spra wl.

Pisarski (1992a) further reports that suburbanites had much greater increases in commute times between 1980 and 1 990 than central city residents. The average traveltime for suburban residents who commuted either to suburban or central city locations increased by 14 percent over the period, while the average commute time for a central city resident increased by only 5 to 7 percent. The extreme outward extension of urban areas may have also increased travel times. Davis (1993) found that the average commute of exurbanites i n the Portl and metropolitan area was seven minutes longer than that of suburbanites, holding constant occupations, household structure, and other factors affecting commuting times. Commute times for residents of urbanited areas outside of central cities were longer than those of central city residents. Thus, researchers have drawn substantially different conclusions sometimes utilizing the same data sets Most of their studies addressed issues other than the effects o f sprawl versus compact developm ent on commuting t ime, however l eaving the results unclear.

evidenced by the debate between Gordon and Richardson (1997a) and Ewing ( 1997). Although government subsidies are a visible part of transit budgets, there is much dissension about what constitutes a subsidy for highways. As Deluchi notes: There is a good deal of argument about whether motor vehicJe users "pay" fully for governmentprovided infrastructure and services (i.e., Lee 1 994: Green 1995) This disagreement, of course, results from different opinions about what should count as a publicsector cost of motor vehicle usc, and what should count as a payment by motor vehicle users for motor vehicle use. (Deluchi 1996, 43) There is a good deal of argument about whether moto r vehicle use r s "pay" fully f o r government provided infrastructure and services. Most federal and state funding of highways derives from the gas taxes and registration fees that are dedicated to highways. However as Hanson ( 1992) Litman (1995) and Dunphy (1997) point out, local governments finance a considerable share of road costs with property and sales taxes None of the costs of t ravel studies have analyzed whether governmental costs vary depending upon the t ype of deve l opment.

l'Jt. Cosb: of On lhe domestic front, there are wide spread policy initiatives that see k to preserve farmland as much with the goal of maintaining a diverse economy as any other reason. Many states (e.g., Mary land, New Jersey, and Vermont) and othe r levels of government (e.g., Lancaster County Pennsylvania) have adopted programs in recent years, ranging from the purchase of devel opment rights to the enactmen t of "right to farm" Jaws, in order to foster land, panicularly farmland, preservation ( Nelson 1992b ). Numerous growth management plans attempting to reverse spraw l include fannland preservation as an objec tive (Maine 1988; Vermont 1988; New Jersey 1991). They address preservation as a goal of planned development, not merely an anempt to curtail sprawl. The limited empirical investigations of sprawl's impact on "co nsumin g" farmland-and in opposit ion, the impact of alternatives to s prawl on farmland-that have been done were performed by Burchell ( 1992-1997) in New Jersey. Lexington (Kentucky), the Delaware Estuary, Michigan, and South Carolina. and by Landis ( l 995) in the San Francisc o Bay area These analyses emplo yed land cons u mption models at the minor civil subdivision level to view differeDCCS between trend devel opment or "business as usual" sce narios and more environmentally co nscious land devel opment approaches. The business-as-usual sce narios embodied sprawl-lik e c haracteristics; the latter. more compa ct, planned development charact eristics. These models allowed future projections of households and jobs to be converted to the demand for residential and nonresi dential stru ctures. and ultimately to demand for residential and nonresidential land with allowances for spillove r to adjacent municipalities and to unincorporated areas. 66 ln both the Burche ll and Landis studies. historical rates offarmland takings were applied to land consumed und er existing development patterns. and the goal of farmland retention was applied under the alternative development patterns. (A similar procedure was used for environ mental land consumption compari so n s.) In the Burchell studies. agricult ural lands included such categories as cropland that is harvested.1aods in pe rmanent pasture. and woodlands that could be used for agricultural purposes. Frag ile environmental lands encomp assed floodplains and wetlands, acreage with s teep s l opes or with critical habitat designation, aquifer recharge areas critical sensitiv e watersheds and s tream buffers ( Burchelll992-l997) Numerous growth management plans include farmland preservation as an objective. The mode l s employing different d e nsities. development loc ations, and occasionally different housing types under the alternatives for future growth, calculated the total agricultural (and fragile environmental lands) that would be consumed. Burchell' s results s h owed savings in the consumption of agricultural acreage of roughly 20 percent in South Carolina, Michigan, and Lexington under plan versus trend developm ent; savings of abou t 30 percent in tbe Delaware Estuary ; and savi ngs of 40 perc ent in N e w Jersey (Burchell 19921997) (See Table s 3 and 4 for details .) Landis's results in the Sao Francisco Bay Area were even more pronounced His "scenario c (co mpact growth) saved n ear l y SO% of farmland acreage and steep-sloped areas, and close to 100% of wetland areas (Landis 1995, 449).

Literatu r e Sy n thesis Matrix X X II.A.2. Reduced Farmland Productivity Allegatio n/Basi s The productivity of land being farmed near scattered sprawl settlements is reduced by the difficulty of conducting efficiem farming operations near residential subdivisions. Subdividing land into smal l lots for residential purposes inhibits fanners' ability to operate on large c ontiguous land parcels and thereby reduces the efficiency of mechanized agricultural operations. Furthermore under sprawl development, subdjvisions and farms may be interspersed, and residents often object to the odors, noise, trock traffic, and other l ocal conditions associated w ith active agricu l tural uses When this contiguous deve l opment occurs, local governments sometimes opt to impose restrictions on fanning. These conditions bring about an "impermanence syndrome'" that is antithetical to sustained farmland produc t ivity. Literature Synthesis There is an extensive literature on constraints to fanning in urbanizing locations (Lisanslcy 1986; Lopez e t a!. 1988; Nel son 1992b). In rural areas that can be readily developed high l and values often shift fanners' "objective function' from agricultural operations to capital gains from real estate sales. Real estate sales, in tum, reduce the average farm size, thus limiting the real i zation of Rvl'g4in arooltl ngs Parsons 8riMitrhoFf ECONorthwest eco n omies of scale-a characteristic of U .S. agriculture A variety of other restraints on farmland productivity have also been imposed, ranging from restrictive regulations t o recurring vandalism All of th ese factors generate an "impermanence syndrome"-a rel uctance by the fanner to invest in new technology and farm infrastructure. Land remains i dle, awaiting conversion to other uses. Studies involving sprawl development allege that this impermanence syndrome is deleterio u s to farmland productivity (AFr 1997). Increasing numbers of farms have been sold and convened into sprawl deve lopment.

The Hinman water demand model includes housing density as one factor a variable clearly different under sprawl versus more compac t development. In a similar vein, the multivariab l e IWR-Main water forecasting model (Ba u mann and Dziegielewski 1990) incorporates in its mul tiple coefficients development density and the number of housing units by type (detached versus attached)-variables that di ffer under sprawl versus compac t develo pment.

The Cosfs of Planning Officials (MSPO) estimates that 20 percent of Michigan s forested, wetland, and steeply sloped areas was lost to development between 1970 and 1990 (MSPO 1995). Numerous growth management plansattempting to reverse sprawl-have evaluated how managed versus traditional development patterns would affect fragile lands. These plans include the Orlando Florida Urban Area Growth Management Program (Orlando, FL 1981 ), the Evaluation of City of San Diego Growth Management Program (1978), and the Report of the Year 2020 Panel of Experts (Chesapeake Bay Executive Council 1988). The Orlando study examined how managed growth versus a "continuation of past trends" would affect the preservation of wetlands and flood plains It projected a saving under managed growth of almost 20 percent in the inventory of these fragile environmental lands (i.e 20 percen t le ss acreage lost). The Michigan Society of Planning Officials (MSPO) estimates that 20 percent of Michigan's forested, wetland, and steeply sloped areas were lost to development between 1970 and 1990. Analyses of sprawl's impact on fragile have been conducted by Burchell ( 1 992-1997) in New Jersey, Lexington (Kentucky), Delaware Estuary, and Michigan. Similar studies were also done by Landis in the San Francisco Bay area.

The Costs of Sprawl-Revisited QUALITY OF LIFE IV .A. Sprawl's Alleged Negative Impacts IV.A.l. Aesthetically D isp l easi n g AllegationiBasis Lowdensity patterns are less pleasing aesthetically and provide fewer cultural opportunities than high density pattems. An important element of the q u ality of life of any community is the aesthetic and cultural satisfaction of its residents in dail y life. If the environmen t !hey normally encounter is dominated by the homogeneous architecture o f subdi v isions and s t rip mall s, the absence of quality civic spaces and landmark buildings, and a la ck of pedestrian-scale ame n i t ies, !he aesthetic satisfaction people derive from their surroundi ngs is reduced Moreov e r sprawl does not easily lend itself to the formation of communities !hat have a feeling of coh esivenes s and can organi7..e to support the arts or other cultural institutions. Literature Synthesis The ae sthe tically less-pleasing aspects of sprawl, such as visual uniformity, are often cited as a cost of this form of development (Ne lessen 1994). Crit ics of sprawl often decry its ugliness. For example, Shore (1995) maintains that "spread city" is inherently ugly because the sett l e m ent pattern has no clear form; retail businesses located along highways must use rau cous" signs to attract passing motorists; and a significant portion of !he land is given over to the Brooking Ponont Brincker+-.oH ECONonhwe s t 7 3 literatur e Synthesil automobile James Kunstl er in a public presentation in Lansing, Michigan in 1996 described U.S. suburbs as "useless and w i thout purpose and occupied by people of the same make-up" (Kunst ler 1996b).

Low-density developments, however, are not necessarily lesspleasing aesthetically than more compact forms of development. Th e aesthetic s vary from development to development. Some low density residential developmen t s, particularly high-income ones, have much more open space and e laborate lands c ape designs than high-density residen tial areas. In fact, defenders of sprawl often contend that the individually owned, discrete open of spraw l make it more attract ive than co m pac t f orms of development. Sprawl does not e a sily lend itself to the formation of commu nities that have a feeling of cohesiveness and can organize to support the arts or other c ultural inst itutions.

Tho Com of Sprowl-llevisited have been used to gauge !he reaction of Americans to sprawl, allhough such studies are often criticized for failing to make a distinction between sprawl and factors not typically associated wilh !hat form of development (e g architectural design). Moreover, survey research does not consistently indicate !hat Americans overwhelmingly find sprawl to be aesthetically less pleasing !han compact forms of development. When shown images of both sprawl and traditional commun iti es, some surveys h ave revealed !hat individuals favor !he latt er by a wide margin (Neuman 1991). But some aspec t s of spraw l appear to appeal to Americans. Individuals were found to favor homogeneous neighborhoods over mixed neighborhoods by a margin of two to one (Bookout 1992). Survey research in F lorida has suggested that individuals there have a strong preference for low density or ex urban living (Audirac and Zifou 1989). There is little evidence within the literature, however, to suggest that Americans find sprawl less attractive than more compact forms of development. On !he subjec t of cultural activities, Shore ( 1995) contends that sprawl does not allow for the formation of conununities that easily organize to support activities such as the arts As a result, low-density residential communities may have fewer and lower-quality cul t ural activities than urban areas. Shore argues that a movement away from "spread city" and toward !he restoration of downtown areas would result in more cultural activities and other services !hat are typically supported by large communities. In general, few argue with !he belief !hat an attractive and aesthetically pleasing conununity increases the overall quality of life. Within !he economics and 7 4 literature Syntfle1it. migration literature, it has been well documented that a community viewed as having a high quality of life will attract and retain individuals. Studies of migration patterns find !hat a com munity's scenery, natural environment, and outdoor recreational opportunities are important factors in attracting and retaining individuals. A survey study of migrants to and residents of 15 wilder ness counties found that scenery and environmental quality were more important factors in attracting settlers than employment opponunities or cost of living (von Reichert and Rudzitis 1992). Two of the most imponant conditions that "lone eagles" (individuals who are able to live anywhere and telecommute to work) cited as influences on their decision to move to the state of Washington were the quality of the natural environment and the outdoor recreational opponun.it.ies found there (Salant et al. 1 996). Cushing (1987) demonstrated that proximity to mountains and coastlines influenced population migration because of these natural resources' aesthetic qualities and the recreational opportunities that they provided. Empirical resultS indicated that interstate were attracted to hilly terrain and major coastlines. As noted. however, there is only some agreement about whether low density developments are aesthetically less pleasing than more compact development patterns. In particular, the literature fails to indicate a significant causal relationship between sprawl and aesthetically less pleasing low-density development; there are numerous examples of unattractive higher-density inner suburbs in the Northeast and Midwest. What !he litera ture does indicate, however, is !hat the aesthetics of low-density areas vary from place to place, and that the preferences of individuals vary from person t o person.

The Costs of Sprowi-Revisited Literature Synthesis Matrix X X IV .A.2. Weakened Sense Of Community Allegation/Basis Low-density deve/opme111 weakens households cow1ections to both t heir inunediate neighbors and to the larger metrOpolitan conununity, and encourages unsocial values. Sprawl weakens the linkages of residents-both among nearby neighbors, and among all other resid ents of their metropolitan area. Linkages with neighbors are reduced beeause low residential density the heavy orientation toward car travel rather than foot travel, and the lack of neighborhood retail outlets and other meeting places diminish i nterpersonal contacts. Linkages with other residents throughout the metrOpolitan area are also diminished by the fragmentation of governance and fiscal resources that prevent commonality of purpose, and by the extreme diffusion of households and jobs throughout an area The resultant loss of sense of community makes it djfficult to generate support for region-wide attacks on social and other problems that cannot he solved by purely local policies and actions. Finally. because spraw l in its most pejorative manifestations is believed by most to he unaesthetic, and antisocial, i t does not nurture the important social values of ecology, sustainability, and conununity. 75 li t eroture Synthesis Literature Synthesis Critics of spraw l often cla i m that a loss of "sense of community" is one of itS greatest social costs (Ewing 1997). Defenders of low-density senlements, however, deny that residents experience any less "sense of community" than residents in big cities or more compact seulements (Gordon and Richardson J997a) In fact, the evidence from as far back as 1954 (Herbert Gans as cited in Jacobs 1961) indicates that some dense areas lack community while some suburban areas have it. Much of the controversy arises because "sense of community" is djfficult to define and even more difficult to measure. In his review of the literature o n "sense of community," Cochrun (1994) finds that the term has been used to describe a number of disparate elements but the most comprehensive definition developed by McMillan and Chavis (1986) McMillan and Chavis identified four factors that contribute t o a sense of community: I) membership; 2) influence; 3) integration and fulfillment of n eeds; and 4) shared emotional connection "Sense of community" is difficult to define and even more difficult to measure. Cochrun offers a definition of "sense of community" that incorporates the four factors identified by McMillan and Chavis: People who have a strong sense of community feel like they belong in their neighborhoods, they believe they exen some control over what happens in their neighborhoods while also feeling influenced by what happens in them, and they believe that their needs TRANSIT COOPERAnVE RESEARCH PROGRAM (JCRP) H-10

can be met through the collective capabilities of their neighborhoods. (Cochrun 1994, 93) In Edge City: Life on the New Frontier, Garreau (1991) searches for a definition of community, particularly within edge cities, and reaches the conclusion that community and neighborhood no longe r mean the same thing. Instead Garreau maintains that "mobility" and "voluntary" are two important tenns that help to defme community-individuals want to be able to both join and leave communities at their choosing. Moreover, Garreau contends that a community should be a "social grouping" that is readily available to individuals and does not interfere with individual freedoms. Curved -Streets and mixed uses help to crea1e a sense of communily. Source: Randa11 Arendt, Rural By Oesig11. I n partial contradiction, Lemann (1989), in an article examining changes in suburban Illinois found that community building efforts in Naperville, a fastgrowing suburb of Chicago, were hindered by tbe high rate of turnover of its residents. Critics of sprawl argue that residents in mixed-used neighborhoods have more sense of community and social interaction than do residents Jiving in low-density developments because they are more likely to walk from place to place and, consequently, they are more likely to Rvtgn lrookingt Ponont &rinoebrhorf ECONorfhw." 76 Utoroture Syntbesis have contact and interaction with others. Residents in low-density areas, on the other hand, r ely more on their cars for shopping and recreation trips and, hence, are less likely to develop contacts and friendships with neighbors (Nasar and Julian 1995). Drawing on the work of Glynn (1981), Nasar and Julian assessed the psychological sense of community across different neighborhoods and housing cond i tions in northwestern Columbus, Ohio. They found that residents of mixed-used areas had significantly more sense of community than residents of single -u se neighborhoods. Opponents of sprawl also maintain that low-density development weakens a "sense of community" by segregating residents (Duany and Plater Zyberk 1995; Kelbaugh 1993). According to Kelbaugh, suburban insularity breeds "ignorance, misunderstanding, and ullimately builds tension" among residents. Kelbaugh prefers high-density, mixed socio economic, racial, and ethnic neighbor hoods because they allow individuals to "rub shoulders" with fellow on a daily basis and work out differences. Similarly, Duany and Plater Zyberk contend that suburban housing fosters a breakdown of the larger community because i t segregates residents by income inlo enclaves. Kunstler (1996a) attacks sub urban sprawl and the zoning laws that have created it. The allegation that low -density residemial living lowers ''sen se of community" may be inferred from his remark that "The model of human habitat dictated by zoning i s a fonnless, soulless, centerless, demoralizing mess .... It corrupts and deadens our spirit." Like Duany and Plater-Zyberk ( 1995). Kunstler argues for development patterns that are mixed-use and provide housing for people with different incomes.

Cosh ol Sprowi-ReviWed Sprawl may weaken not only neigh borhood connections but also connections between family members who occupy the same residence Some contend, for example, that sprawl reduces the amount of time parents spend with their children because more households must have two people working outside the home in order to pay for the multiple automobiles r equi red by daily lifc.2 This need to support the household 's transportation facilit i es may, in fact, even reduce the quality of child care provided by parents. Some contend that mothers working outside the home provide lower quality child care than those who stay at home. The subject is fraught with controversy (Joseph 1992). Meanwhile, Kelbaugh (1993) examines another potential noneconomic social cost associated w ith sprawl-the tensions that result from parents spending long hours commuting instead o f with their childre n or each other. Sprawl may weaken not only households' connection s to neighbors and the larger community, but it may also weaken connections between family members who occupy the same residence. The literature does not readily provide support for the opposite allegation-i.e., that lo w-density development strengthens households' connections to both their neighbors and large r commun ity. Ewing suggests, howev er, that low-density development does not provide residents with any less "sense of community" than higher-density development. After reviewing extensive literature on sprawl he concludes that there is not enough 2 Some have argued chat e\en i f only one person working outside the home could support a one-car family, mo5t residents of sprawl seulemenl!:i need two cars for conductin g daily family lif e. The low. densit y pauem of both hous-ing and jobs makes u.se of public transit impractical for commuting and daily ertandrunning. 77 Sprawl development may be seen as a continuation of the "prairie psychology" of early American settlers who believed they could change their current situation by leaving existing homes and problems behind and moving west onto vacant land. evidence to determine whether a lack of an identifiable community is a_<;Soc iated with sprawl (Ewing 1994). One further issue related to a lack of "sense of community" is the emergence of a "throw away" mentality or, more elegant ly, the lack of value for ecology and sustainable life styles. Some argue that sprawl encourages the "throw-away" menta lity among households. In a sense. sprawl development may be seen as a continuation of the "prairie psychology" of early American settlers who believed they could change their s i tuation by leaving ex isting homes and problems behind and moving west onto vacant land (Delafons 1962). More recently, millions of American households have moved out of central cities and older inner-ring suburbs for the same escape the problems of those areas. They have left the problems behind for others to solve Few, if any, studies of sprawl have dealt with this issue, and none have proposed any way to measure the "throw-away" mindset.

IV .A.3. Greater Stress Allegation/Basis Because people spend more time driving they have less free time and more stress. This allegation has two components: ftrSt, that sprawl increases the time people spend in cars relative to higher-density fonns of development and, second, that increased travel time leads to stress and other impacts. I t has also been alleged that commuting through the aesthetically unattractive environments of commercial strip developm ent that are typical of sprawl produces more psychological stress on commuters than would commuting through environments dominated by trees and open space. Literature Synthesis Here, as with many of the topics evaluated in this report there is substantial overlap with other topics and their alleged effects In this case, the overlap is with transportation which include allegations about traffic congestion and travel times. Much of the debate about commute time has been based on data that compare travel times for residents of suburbs and central cities. There is little data on travel times associated with density of development. Ewing ( 1997), in his analysis of household travel patterns in a sprawling Florida county, purports to show that households living in the most accessible areas spend about 40 minutes less per day traveling by vehicle than do households livin g in the least accessible locations (Ewing 1995c; Ewing ct al. 1994). Ewing states that this savings in traveltime is due almost entirely to shorter auto trips, and that the s i gnifican t land-use variable affecting travel times is regional accessibility, not local density (Ewing 1997). 78 literature Synthesi.t There is also evidence that greater commuting time increases the stress of commuters Novaco et al. (1990) found that increased travel impedance, as measured by commuting distance and time, i s associated with increased measures of stress. Travel impedance was also found to have statistically significant effects on job satisfaction, work absences due to illness, and overall incidence of co lds or flu. Subjective or perceived condi t ions of travel impedance were found to have statistically significant effects on mood at home in the everting and chest pain. Consequently, the study found that job change, in its sample, was primarily related to commuting satisfaction The study validated results from the author's previous work, which had found that impedance characteristics of commuting raise stress levels as measured by effects on blood pressure, tolerance for frustration, negative mood, and overall life satisfaction. This earlier work also found tha t the desire to change residence because of transportation conditions was related strongl y to high impedance (Novaco et al. 1979; Stokols and Novaco 1981; Stokols ct a!. 1978). The physical stress effects of impedance have also been corroborated by a study of the effects of average commuting speed on blood p r essure and frustration levels (Schaeffer et al. 1988). Increased travel impedance, as measured by commuJing distance and time, is associated with increased measures of stress. Koslowsky and Krausz ( 1994) directly addressed the links among commuting time stress, and workers' attitudes toward their jobs, in a statistical analysis of survey responses from more than 600 nurses. The researchers found that com muting is a poss ible source of recurrent stress, which can lead to undesirable organizational consequences. This study TRANSIT COOPERATIVE RESEARCH PROGRAM /TCRP/ H-10

Th Costs of also found that the correlation between commuting time and stress was stronger for tbosc who drove to work than for those who used public transit. But the authors do not rigorously explore the reasons for this difference Koslowsk y and Krausz do cite prior litemture that found a relationship between the commuting experienc e and such organizational outcomes as absenteeism (Taylor and Pocock 1972), lateness (Gaffuri and Costa 1986), and turnover (Seyfarth and Bast 1986). Although the link between commuting and stress is weU established the li terature on the stress effects of commuting does not rigorously address the link between commuting stress and the density of deve l opment or urban form. Novacoet a!. (1990) begin to address this link with their finding that stress effects are strongly associated with freeway travel and with road exchanges ; they also assert tha t freeway travel in s outhern California has become increasingly congested because roadway capaci t y has not kept pace with continued growth. Lilerature on the stress effects of commuting does not rigorously address the link between com muting stress and the density of development. Although it has been alleged, as noted e arlier, that commuting through the aesthetically unattractive commercial strip development typ ical of sprawl produces more psychological stress on commuters than does commuting through envirorunents dominated by trees and open space, very little literature pertaining to this allegation exists One study, however, claims to have tested com mu ters psychologically and arrived at a finding that supports this claim (Ulrich et al. 1991).

Sprawl is alleged to generate more vehicle miles of travel than other forms of development and t o produce more total vehicle emissions as a result Under many local climatic condi tions, this can generate a greater total amount of air pollution, even though i t may result in less intense local pollution than would occur in some very high density portions of more compact regions.

Therefore, low-density settlementS are presumed to generate more auto-oriented emissions per 100,000 residents. However, the intensity of air pollution in each metropolitan area is affected by ntany factors, including the locat ions of major urban centers, prevailing winds, mountain barriers, temperature inversions, and general climate.

Lessened Historic Preservation Allegation/Basis SWI:nMI Oi'.OI:If..,.n t X Sprawl makes it difficult to preserve historically older structures Sprawl encourages economically viabl e firms and households to leave inner-city neighborhoods by permitting them to move to the suburbs without paying the full marginal costs of their doing so. In particular, those who move are no t required to compensate those who are excluded from suburban communities for losses the residents that remain behind suffer. Therefore, the economic base supporting older structures of historical significan c e located in inner-city neighborhoods i s weakened Neighborhood conditions in the vic inity of such structures also worsen because of the increased concentration of p<>verty; his t oric structures located there are eventually consumed by these forces. 81 lito.rahlre Syntho.Ms Literature Synthesis This allegation has been put forward main ly by t he National Trust for Historic Preservation in its various publications attacking sprawl. The following argument (Beaumont 1996a) summarizes the reasoning behind th e professed association between sprawl and preservation. Beaumont is one of the few obse rvers of sprawl w h o has commented on whethe r or not this association is valid Accord ing to Beaumont, sprawl affects historic preservation in five major ways: I) Sprawl adversely affect s older dowmown areas and neighborhoods, where historic buildings are concentrated. When the economic vitality of a historic area suffers, the buildings in it often become u n derused or empty. Over t ime, many of them are "demoli.shed by neglect" or tom down to make way for surfac e parking lots. 2) Sprawl destroys community character and the countryside. Cohesive main streets, old stone fences, historic trees, country roadsthese and other features of the American lands cape are rapidly being destroyed by sprawl development and the vast expanses of asphalt required to accommodate it.

By scattering the elements of a community across the landscape in a haphazard way, sprawl provides no town centers and reduces the sense of ownership-and therefore also the commitment-that people have toward their community. 4) Sprawl forecloses alternatives to the automobile as a means of transport, thereby adding to pressures to cr eate or widen roads that often result in the demolition of historic resources or the degradation of their settings. 5) Sprawl leaves old e r cities and towns with excessively high concemrations of poor people with social problems, making these places a very difficult environment in which to revitalize communities.

Preference for Low Density Living Allegation/Basis -"' Many households prefer low density residential living. Many consumer preference surveys reveal that a key part of the "American dream" is ownership of a detached, single-family home with attached private open space in the fonn o f a backyard. More important than the stated preference, however, is the revealed preference : for the last 50 years, suburban development has been the 82 literoture see.sis primary fonn of metropolitan residential growth, and single family hous ing units have been the dominant residential fonn. Consumers clearly choose low-density suburban Jiving given existing alternatives and prices. Most housing developers consistently build low-density subdivisions because they are easier to market than higher-density developments. In order to make this low-density single family, detached housing affordable to most people, it is generally built at the urban fringe where land prices are lower (Downs 1994). Literature Synthesis The suburbanization of population and jobs in the United States has been well documented. In 1950, almost 70 percent of the population of 168 metropolitan lived in central cities; by 1990 over 60 percent of the population of 320 metropolitan areas lived in the suburbs, and a majority of jobs in metropolitan areas were in the suburbs as well (Rusk 1993). The process of suburbanization has lo wered average population densities in urban areas. Between 1 950 and 1990 the number of residents in urbanized areas, with populations over one million in 1990, increased 92 percent, while average population density decreased 44 percent (Wendell Cox Consultancy 1996 ) The fact that so many Amer i cans choose to live in low-density areas has been cited as strong evidence that Americans prefer that lifestyle.

(Ewing 1997) In his earlier study, "Characte ristics, Cause s, and Effect s of Sprawl: A Literature Review," Ewing (1994) offered additional evidence to bolster his contention that consumer preference surveys do not clearly suppo rt low density li viog ove r more compact forms of selllemen t Surveys where people are sbown images of both sprawl and traditional communities reveal that, for the most part, the latter arc favore d by wide margins (Neuman 1991 ).

Recent choice of U.S. households has been for low-density suburban living over high -densi ty urban living. Other surveys of consumer pre ferences have also shown mixed resu lts. A September 1995 survey of people who shop ped and ultimately bought units in p lanned communities indicated that 57 percent of the respondents agreed with the s tatement "I'm tired of living in the st erile uniformity of most su burbs ."

The question about whether sp rawl is s trongly linked to these residential c h oices is a matter of interpretation. At one extreme, the choice of low-densit y h ousi ng is, in essence, the definition o f sprawl, so the question of whether it is caused by sprawl is a circular one Another interpretation is tha t the mere existence of the pattern (sprawl ) and its accompanying low-density h ousing influences people's preferen ces, like the adv ertising of any product.

On the other han d, 1 2 percent of urban r es idents, com pared to 9 percent of s ubur ban res iden ts, felt their safety had increased over the past year ( Pastore and Maguire 1996). Through interviews, Hummon (1990) determined that rural residents view dang er as both an integral p art of city life and an indicator of social p rob l ems. U rban residents, however consider crime and danger to be more a factor of socioeconomic conditions and location than an integral part of city life. Using surve ys of lo w-income, si ngle mother s, Co ok (1988) found that urban women were two times more like ly than suburban women to indicate they felt unsafe in their a partments and neighborhoods. R esearche r s w ithin the criminal justice field concl ude that percepti o ns of crim e and security vary with site chara cteristi cs and socioeconomic conditions; thu s, fear of crime does not always accurarely reflect actual crime rates. Instead, fear of crime is often derived from incomp let e knowl edge of crime rates, o bservable evid ence of disorder, and prejudices arising from neighborhood chang e (S kogan 1986). Other studies conclude 86 that the direct effec ts of the phys ical envir onment on crime rates range from small to moderate ( T aylor and Goufredson 1986). A low c rfme rate is one of the top 10 qualJtyoflife chara c teristics desired by Money magazine subscribe rs.

Studies have found that the effect of physical environment on crime rates ranges from minimal to moderate and that crime is more a factor of socioeconomic conditions than density. An argument might be made that sprawl reduces crime ra te s in a round about way-sprawl is correlated with higher incomes which, in rum, are often corre l ated with greater spending on home protection and public safety.

B. 3. Reduced Costs of Public and Prhate Goods Allegation/Basis Many households find the cost of public services and some private services in suburban locarions a better value. For the public sector, suburban locations often provide better services (especially schools) for an equivalent or lower tax burden. For private-secto r goods and services, particularly retail sales, the lower land values in suburban areas aJJow lan d intensive development formats which include expansive ("big box") floor space and parking. These development formats, in tum, attract high-volume low-cost retailers 87 Literature Synthesis The alleged benefit for public services substantially overlaps the alleged benefits reviewed und e r the heading Social Issues in this literature review. Two of the alleged benefits discussed there are germane here: I) The ability of jurisdictions to define a relatively homogeneous population with relatively similar service needs (which also provides opportunities for both economies of scale and concentration), and the ability to drop services not needed by the homogeneous population (i.e., social services for low-income households) 2) The ability to have different tax levels and service qualities. There is an ongoing professional debate about the institutional structures by which public services are most efficiently and fairly provided and a large body of literature on the subject. Not surprisingly, the poles of the debate are occupied by those who believe in the efficiency of markets and those who believe markets operate imperfectly without government imervention In the 1950s, Tiebout ( 1956) laid out the basic arguments for market choice (which, when applied to government, is sometimes referred to as "public choice"). He argued in favor of multiple small governments that allow households to "vote with their feet choosing to Jive where th e combination of public services, quality, and cost best meet their preferences.

The Cos ts o f In contrast are those who argue (see, for example, Foster [1996]) that typical market failures in the provision o f public goods require larger units of governmen t so that external costs can be internalized, increasing tbe odds that s u ffic ient public goods will be provided. Arguments are made for the i mprove ment of both efficie ncy and equity. Because this topic is considered else where in this report, it is merely alluded to here. Tbere is certainly no agreement on this subject. Nor is any likely. since to come to a conclusion would require, among other things, agreement on t wo issues on which peop le s opinions derive as much from underlying philosophies as from the results of social science: I) the proper scope of government intervention, and 2) the trade-offs between efficiency and equity For private goods there is ampl e anecdotal evidence that big box retai l ers make their money by high volumes on low margins, which for consu m ers means low cost. The growth of these retailers (e.g., Wal-Mart, Home Depot, Cost co) is evidence of demand and suggests that they are giving consumers more of what t hey want. Additional anecdotal evidence sugges t s that many people who would oppose such retailers in their neighborhoods are some of the same ones who drive, often substantial distances, to shop at these stores in other parts of a region. T he n ext quest ion, howeve r is: To what ex t ent are low-density development patterns essential for these cost savings? Recent work done to help evaluare the impacts of managed growtb plans for metropolitan Portland, Oregon (ECONorthwest 1996) sheds some light on this issue. After q u antifying vacant land supply, researchers conducted focus groups and work sessions w ith retail Rutgert Brookings 8rnckr'hoff ECONortflw .. 88 literature Synthes.ii developers and brokers. Their opinion was that to satisfy today's consumers most retail development had to a c commodate the automobil e, and as a resu l t, vacant, lowpriced l and in sizable parcels was critical to retail development, especially big box retail. High density areas are likely to have higher land values, less vacant land sma ll er parce l s, and more existing residents to oppose the new retail development. A few central cities have seen new discount retailing. In most cases, however, the development has occurred on underutilized industrial parcels whose zon ing either defin es the retail use s as compatibl e or makes variances easy to receive. In these cases, low-valu e land is still the primary fact or all owing the development to proceed. Market f ail l!res in the provis,ion of public goods require larger units of government so that external costs can be in ternalized. There is reasonable evidence to conclude t hat people want goods at lower pr ices in lower density partS of metropolitan areas. As with other effects whether sprawl causes this effect is a matter of int e rpreta t ion. On one hand, spraw l is the e ff ect; the low-density retai l pattern i s what enables retailers t o reduce prices. On the other hand, a p attern of sprawl may be causal if it implies mor e retail of the same type is desirable and allowab l e, and if it creates a pattern that allows more lowcost land to be developed more easily. Sprawl probably does both.

are most often addressed in argumentS against policies t o limi t sprawl. Th ese argum ents are base d on the co n sid erable literature that shows that i n creas ed density increases the cost of land It is argued that an increase in density will reduce job growth and economic development opponunity by increasing the cost or limiting the number of si1es available for commereial development, and by increasing the cost of housing, wbich in tum will limit the supply of labo r (ECONonhwest 1994) There is considerable evidence that measures to control growth cause the price of l and to increase. S hilling et al. ( 1991) found that state landuse co ntr o l s both restrict the supply and increase the demand for residential land, driving up itS price. Brueckner (1990) cites a larg e empiricalli1erature documenting the effectS of growth controls on housing and land marketS. His evidence pointS to the fact that growt h controls raise housing prices in communit ies where they are established (Dowall and Landis 1982; Katz and Rosen 1987; Sch wanz et al. 1981, 1989). Growth controls rai se housing prices in communiti es wher e they are eslDblished.

high proportions of very poor residents within older, deteriorated neighborhoods fosters conditions that are adverse to the welfare of residents. These include high rates of crime, drug abuse, delinquency, births out of wedlock, welfare dependency, unemployment, alcoholism, and mental illness. In addition, the quality of education received in public schools in these areas, or where children from such areas dominate, is very low Literature Synthesis There is some disagreement about tbe degree to which suburban exclusionary zoning is for poverty concentrations in core-area neighborhoods. Some observers believe other factors are more important in produc ing such neighborhoods. The se other factors include negative behavior patterns among the that make them unwelcom e elsewhere; the concen tration of deteriorated, very low cost housing in such neighborhoods which attracts people who cannot afford better accommodations; the concentration of public housing units in such neighborhoods; the lack of public transportation in suburban areas that makes it difficult for poor persons without cars to live there; and the desire of poor households to li ve together in neighborhoods where public services aiding the poor are more easily accessible In contradiction, recent findings in New Jersey from the New Jersey Council on Affordable Housing (COAH) and similar findings from the Gautreaux (Chicago) and Special Mobility Program (SMP) (Cincinnati) studies indicate that those who occupy affordable housing in more suburban locations take on the employment characteristics, ambition levels, and success rates of the population of those jurisdictions (Davis 1993; 91 Fischer 1991; Wish and Eisdorfer 1996). In New Jersey, close to 15,000 afford able housing units have been built and occupied as a result of legislation emanating from the series of Mt. lAurel cases in that state. Occupants of these housing units are employed doing well at local schools, and inte grated without incident in neighbor h ood s they would not have had access to without the court decisions The Gautreaux and Special Mobility Program studies show that residents moving from the central city to the suburbs using housing vouchers have higher rates of employment and higher salaries, and their children have beuer school attendance and higher grades, than families who choose not to move. While the confounding issue of self-selection is clearly present here-i.e. the successful and ambitious families are the ones that opted to participate in the moves-a growing body of literature indicates that "place matters. T here is a "rub-off' effect of place wherein success patterns can be communicated by residents to newcomers who specifically wish to improve their current economic and social positions (Poisman and Botein 1 993).

The unlimited extension o f urbanized uses on the periphery of the metropolitan areas permits many employers to move to locations that are very far from inner-city neighborhoods. Consequently, unemployed workers Jiving in those neighborhoods can neither readily learn about job opportunities in farout locations nor afford to commute to such jobs even if they learn about and qualify for them. This mismatch aggravates both high rates of unemployment in inner city neighborhoods and suburban shonages of unskille d labor. Literature Synthesis John Kain (1992) was one of the frrst to examine whether a mismatch exists between the increase in lower-skilled and otherwise attainable jobs in the suburbs and the high levels of unemployment of residents in central cities who should be able to access these jobs. Spatia l mismatch has also been examined by sociologists John Kasarda ( 1990) and William Wilson (1987) and by economists Keith lhlanfeldt and David Sjoquist (1990) Although the original literature related the mismatch to black workers of all ages, later studies focused on the spatial mismatch as it affected young black workers. Race as the causat i ve agent i s the main focus of inquiry throughout most of the studies mentioned above In other studies by Bennett Harrison (1974) and John Kasarda ( 1990), causes of the mismatch (which according to them may not be spatial) are extended to the inadequate skills and education of young black workers, and limited transponation or access to transportation. Findings on spatial mismatch, although not always consistent in unearthing a spatial 92 literature S)'!lthMis component (s ee Bennett Harrison [1974), David Ellwood (1986). and Jonathan Leonard [ 1987)), are persistent in their specification of a mismatch of some type Poor inne.--city residents often cannot reach jobs located in the suburbs. Source: Truman Hanshom. Interpreting the Cit). The reality of this mismatch is a population desiring to be employed in one location and available jobs going unfilled in another. Often, the unfilled jobs are lower order jobs that are not worth accessing by public transit if the prospective worker must also pay for child day care services to retain the job. Other jobs similarly located in the suburbs may require skills that applicants, even after training, cannot meet. Or they may be jobs that casual workers available during the summer or during college breaks can easily meet without training. The confluence of elements that create spatial mismatch is so complex that sprawl versus more compact development patterns probably play only a small role. Spatial mismatch will grow to be a major issue with significant consequences as workfare replaces welfare Moreover, the relationship between sprawl and central city unemployment rates, the bottom-line issue of the above discussion, is even more complex than relationships between sprawl and spatial mismatch TRANSIT COOPERATIVE RESEARCH PROGRAM (TCRP/ HIO

Fosters Residential Segregation A llegation/Basis Residential segregation by race and income is greater under sprawl than where less fragmented govemance over land uses exists Exclusionary zon i ng by many outlying suburban communities inhibits the c o nstruc tion of relatively lowcost housing for lowand moderate income households This occurs because residents of each community control land use decisions therein.

They have compelling economic m otives for trying to minimize the number of low cost housing units within their own communities. These include maintaining housing prices as high as possible and excluding households whose need for public services-especially schools-will cost the community more than the taxes these households will contribute to the community Because Blacks and Hispanics have much lower incomes, on average, than o t her major groups in American society such income s egregation is also an effective means of achieving ethnic segrega tion in many areas. Literatur e Synthesis There is on l y partial agreement about this allegation Such a small number of metropolitan areas without f ragmented governance over land uses exist in the United States that statistical testing of conditions in them versus conditions elsewhere probably are not valid. Yet coming at this issue f rom another direction, those states and regions that have made overt efforts to provide affordable hous ing in locations where it has not before existed are achieving integration in those locations. In New Jersey where a municipali t y must provide its f air share of affordab l e housing or lose its right to zone, racia l and ethnic integration is taking place in what were once predominantly white outer ring neighborhoods. New Jersey's affordab l e housing program requires t hat those who fill muni cipal quotas come from outside the m u nicipality's boundaries but inside its commu t ing region. There are strict advertising and queuing requirements that ensure that minority households in central cities have an equal chance to occupy affordable housing in the suburbs.

Worsens City Fiscal Stress Allegation/Basis Under sprawl, central city govemmeflfs become fiscally strapped or "squeezed," because they must provide costly services to large numbers of very poor hou seholds, while the propenies owned, occupied, or patronized by such households produce relatively low per capita tax revenues. Low-income neighborhoods in panicular have higher costs of crime and fire prevention, street cleaning, and public health and welfare services than middle and upper -income neighborhoods. Y ct the former produce lower property and sales tax revenues per capita than the latter. This situation forces city serving such communities to either raise taxes above those in surrounding communities or to provide lower quality and quantities of key public services to their residents. or both. 94 liJerotvr Synrht$4 Literature Synthesis Only limited agreement exists on the extent to which sprawl is regarded as a major cause of fiscal stress. The concentration of very poor households within inner-city neighborhoods is surely not caused solely by suburban sprawl; many other causal factors largely unrelated to the specific form of growth within a metrOpol.itan area also contribute to this resulL Unfortunately, it is probably impossible to decide scientifically how to allocate "responsibility" for this outcome among these causal factors-a fact which presents an obstacle to "proving that sprawl contributes significantly to this outcome.

Fosters Home Rule AllegationfBasis Sprawl keeps govemmenl decisions about land use at the local/eve/, where individual citizens have much more chance of influencing the results than they do where regional d ecis ion maldng predominates. Because sprawl involves fragmenlation of government powers among many relatively small localities, i t keeps land use decision making closer to the people most directly affected by it. This satisfies the strong American desire for local sovereignty. Like-minded citizens can pass zoning and other regulations that exclude types o f development from their communities they do not like. This in tum allows them to prevent "socially undesirable" influences in their neighborhoods and schools Such negative influences include potentially dangerous households with characteristics markedly different from the ir own, as well as region-serving land uses with negat ive local spillovers, like airports or incinerators Literature Synthesis The literature dealing with the merit of home rule praises "small government" democratic responsiveness, as is illustrated in the following quotations: Others came to suburbs for better schools. This has been due, at least in part, to the responsiveness of these schools to parental expectations rooted in tum in the sm aller size of many suburban school districts. Indeed, in an age primarily given over to state centralization, the suburbs have encouraged a countervailing decentralization governance, forcing a healthy kind of competitiveness onto local governments.

significant choices of communities, and within a fragmented area, they h ave even more choices. Sprawl's contr ib ution to diversity in choice is the ma ssive amount of reasonable alternatives (not best or worst) that it offen the locational consumer Those who "sho p for communities take all of the elements listed above into account before malting a locational decisio n Sprawl's contribution to diversity in choice is the massive amount of r eason able altern atives (not best or worst) that it offers the locat ional c onsumer. Fragmented government s, primarily suppo rting residential housing, offer infinite variations of the bundles of housing, public services, and tax str\!Cture described above. Most of the varia t ions found at the periphety of me tropolitan areas are superior in housing value, school s y s t ems, p r operty tax levels and housing a m enities to locations found closer in. As such, these are the locations most often souglu; the closer-in commurtities are the locations most often left behind. The most significant vari a bles appear to be housing cost and housing appreciation, which in combination appear to be maximized in locations more distant from, as opposed to closer t o, the urban core (Downs 1994).

TOP I CAL C OVERAGE DATA BASES, METHODOLOGIES D EFICIENCIES Necessary Disclaime r s One logical s tarting point for summrui.zin g the literature and analysis of thi s chap t e r is to review the distribution of the studies by t opi c and to see where there is more or less topical coverage This can be done quantitatively, that is, by examining bibliographies on the topic--such as the one assembled here (see Chapter Five), or by Ewing (1997), Gordon and Richardson (1997 a), or the Growth M anagemen t and Research Clearinghouse ( 1 993). An overview of the literatu re cou l d also be made by tabulating the numerical distribution of studies by subject type. This procedure raises i ts own issues, however, such as bias in the respective bibliographies (i.e., those emphasiz.ing studies critical versus supponive of sprawl) and differences that reflect the varying professional orientati ons of the bibliography compilers ( i.e., tr affic eng in ee r or historic preservationi s t) In doing a q uantitative census of the li terature and topi cal coverage of sprawl, there is also a question of how to count multiple studies by the same author o f a similar type.

Should Dow ns's pro lific publications involving the iss ue of suburban exclusion of minorit ie s which in some cas e s co ver s imilar materials be individually counted (Downs 1970, 1973, 1981, 1985, and 1994)? The same problem of counting arises with the parallel series of publica t ions by Gordon and Richardson (1989a. 1994a. 1996, 1997a. 1997b). Ewing (1994, 1995a, 1997), and Burchell (1992a, 1992b, 1994, 1995, 1996. !997a 1997b) Another issue in undenakin g a numerical tally of the literature i s whether all entries should be weighted simil ar ly. Do The Cost s of Sprawl (RERC 1974) and the New Jersey Impact As sessment ( Burchell 1992a, 1992b)-both influen tial analyses of hundreds of pages each-" weigh" the san1e as briefer and less subs tantive discussions? Over and above these questions, an attempt to quantify the topical coverage of the literature on sprawl is fmstrated by s u c h fundamental issue s as what i s meant by s prawl and what countS as literature on thi s subject Often sprawl is not defined in the literature, and i t s full elemental characteristics are not universally agreed upon. Should the literature tbat is t o be tabulated consis t only of materials on sprawl pe r s e (i. e. exam inati ons of sp rawl' s effec t s on inframucturc costs ) or s h ould it include broader topics relevant t o a discussion of spra wl? The quality of life (QOL) subset in this report is illustrative ; there is very little literature directly dealing with QOL and sprawL But there are many more studies on QOL that show impacts on quality of life by fonces analogous t o spra wl. Even though there are persistent problems, some general ce n sus of the approximately 500 citations in Chapter 5 is Since more than a year has been spent assem bling, categoriz.ing, and analyzing the literature. clearly some statements ca n and should be made co n cerning its topica l concentration and, as well. methods and databa ses reli ed upon In the following analysis, except for related materials such as dictionaries and encyclopedias; economics, land use, housing. and zoning te xts; and so on, all of the remaining 475 citations ane in cluded and counted equally Citations are made pan of the analy sis whether or no t they repeat informat i on of anoth er study or deal directly or indirectly with sprawl.

M e thodologies Sprawl Literat ure The re are differences in the analytic quality o f the literature, as is indicated in the tab l e at the top oflhis page. In terms of analytic methods employed, transportation and travel costs have !he most quantitative analyses (col umns 2 and 3), followed by public and private capital and operating costs In reverse fashion, land/natural habitat preservation and quality of life have the least quantitative and the most descriptive analyses (co lumn 1). The more rigorous quantitative simu l a tions are found in public and private capital and operating cost studies, whereas transportation and travel costs studies rely most on the U.S. Census, the Nationwide Personal Transportation Survey and other empirical data.

Beyond this gross categori7.ation, little can be said except that studies in the "harder'' impact categories appear to address sprawl directly and by that term, whereas studies in the "softer" impact categories typically address sprawl indirectly as a form of low density exurban or fringe-suburban development. Exa m p les o f Data Employed by Imp ac t Cat egory The five impact literature categories int o which this report is divided apply both common and sub j ect-distinctive data sources Across all categories, soc i o economic information from the decennial census (population and housing), the triennial American Housing Survey (AHS), and similarly broad databases are frequently tapped Both published (e.g printed census reports) and compu t erized (e.g. Public Use Microdata Sample of the decenn ial census) sources are accessed Land-use information of various types is also employed across all literature categories. These include both descriptors o f a gross or aggregate nature, such as population density derived from the County and City Data Book, and finer grained land-use 100 TRANSIT COOPERATIVE RESEARCH PROGRAM (TCRP) H-1 0

{e.g ., providing security for petroleum sources), t o global warming. One final note: Much of the data in the sprawl literature is of a secondary nature-that is, collected by one party and reanalyzed or cited by another. The Co.rts of Sprawl neighborhood protot ype data originally assembled by RERC in the early-to mid-1970s (see Table I), for example, is still being relied upon some two decades later by commen tators on the subject of sprawl (AltShuler and Gomez Ibanez 1993; Ewing 1997: Gordon and Richardson 1997a) Exa mple s of M ethods E mployed by Impact Category Multiple choices are available to the analyst when considering specific meth ods As mentioned previously, one choice is empirical-that is, one that observ es something tangible : another method is a simulation wherein events are modeled rather than observed. Both types are found in the literature on s prawl, with the incidence varying by subject. In the public and private capital and opera ting costs literature, because development's effect on infrastructure is projected into the future, many studies are simulations. Among these simulati on s tudies are The Costs of Sprawl { RERC 1974); Downing's (1977) capital exten sion supplement to RERC's original work; Peiser's ( 1984) analysis of infra structure costs in a hypothetical large subdivision; and Burchell's ( 1992-1997) and Landis's (1995) analyses in New Jersey, the Delaware Estuary, Kentucky, and Michigan (Bwcbell ) and Cali fomia (Landis). Operating costS, including operating expenses per c apita, are also simul ated in these types of studies { al though not necessarily linked to develop ment pattern): other financial parameters, such as tax rates and levels of intergov ernmental revenues, receive similar llteroture SyntheP. treatment Udd's (1991) regression analyses relating density to per capita government operational spending, and the DuPage County {1991) regression of observed nonresidential development to observed tax rates, are good examples. A s noted earlier, because travel informa tion i s routinely studied and counted, much of the literature on transportation and travel costs is empirical Examples include Pushkarev and Zupan's srudy ( 1977) linking density and transit use in 100 urbanized areas; Cervero's (1989) study examining density and modal choice in 57 "su burban employment centers"; and Parsons and ECONorth west' s (1996) study examinin g the effects of density. urban design, and mixed use on the demand for transit in various locations, ranging from II metropolitan areas to individual cities (Chicago and San Francisco). At the same time, the transportation and ITavel costs literature, reflecting the underlying discipline of transportation engineering with its model ing prowess, also in corporates some large -sc ale simulatio ns, such as the 50year simulation by Metro ( 1994 ), and Downs's (1992) Stuck in Traffic modeling. The remaining literature categories (I.Aiui/Natural Habitat Preservati011, Quality of Life, and Social Issue s). though they apply some simulations. such as The Costs of Sprawl modeling of lan d consumption in alternative neighbor hood prototypes, arc largely a combination of empirical and descriptive analyses. The Green Index of locations (Hall and Kerr 1991) incorporates more than 250 quality-of life indicators relared t o environmental quality {e.g., air and water pollution, and community and workplace health statisti cs).

The cas e s tudy and per capita engineering studi es are commonly u sed to describe what occurred at one or more locations. Exampl es of th.is format include Duncan's ( 1989) analysis o f infras tructure costs in a number o f Aorida developments ; E wing's {1995b) analysis of household travel patterns in a Aorida county; and Ewing. Haliyur and Page (1994) and Cambridge Systematics (1994) examinations of travel in Palm Beach County, Florida and Los A nge l es, C alifornia, respectiv ely. Not c oincidental l y, most of the case analyses and pe r ca pita engineerin g studie s are focused on l ocat ions e xperiencing rapid growthoften Sunbelt l ocations In fact, so many of the investigations of travel profile as it relates to urban design have taken place in Califo rnia, especially around San Fran cisco an d Los Angeles, that questio n s about tbe replicability of the results observed to the res t of the counlry are beginning to be rais ed by tne research community. Descriptive analyses are found in signifi can t numbers in the impact categories o f landlnarural habitaJ presetWtion, of life, and social issues. These analyses include Arendt's various ( 1994a, 1996, I 997) guides to devel oping with ope n space ; Kunstler' s (1993) description of urban and suburban neighborhoods; and Moe and Wilke's (1997) prescription for improved metropolitan areas. Various q u antitative skills are incorporat ed in the literature The per capita infrastructure studies, for instance are esse ntially ari thmetic compilations; but higher order applications are also found, especially within the transportation and travel cost s analyses. These s tudies apply such sta tistical testS as analysis of variance-e.g., comparing travel be h avior in auto-oriented versus transiH>riented neighbo rhoods (Handy 1995) a nd multivariate regression-e.g. u sing r egre ssion to show that much of the variation in transit use can be explained by density (Pus hkarev and Zupan 1 977). Even the most "statistical" of studies, however. are s till cross-sectional In the travel literature, for examp l e, they show the correlation between current urban form (i. e ., low to high densities. and segregated or mixed uses) and current travel be havior (i. e., mode choice or VMT). But they do not show b ow changes in urba n form have influ e n ced change s in travel choices Thi s i s one of numerous deficiencies in the literature noted below.

Surpri singly, the landmar k s tudy, Th e Costs of Sprawl (RERC 1974), did not d efine sp rawl explicitly, and the omis s ion of a definition has continued throug h out the literature. Where sprawl is defined, or at least characterized, reference is often made to a limited number of traits such as low-density or leapfrog scaltered development (Ewing 1997) Many studies, however, omit s evera l other defining traits that cause many of the all eged negative impacts of sprawl, suc h a s dependence on the automobile and fragmentation of governm ental l and use authority.

T herefore, a ke y pan o f this literarure sear ch is to s pec ificall y rel a t e the negat iv e and positive impacts of spraw l to their defming characteristics. Almost no analy ses o f sprawl adequately define it. 3 Other definitional cum measuremenJ questions remain Take, for instance, "den s ity." S everal studies focu s on t h e density of a region and relate ce rtain c harac t e ri s t ics, s u ch as travel behavior or infr astructu r e co s t s to the region's density Ho w e ver densities vary widely with i n regi o n s and the real question is: How does t he density of the specific places where people Jive and work affect say, their travel c h oices? The densities of these places may be substantially different from region w i de averages For instance Gordo n an d Richardson (I 9 89b ) u se SMSAs as the unit o f measurement in their analysi s of d ensities and commuting times in 82 SMSAs. But i s this meaningful, give n that no SMSA bas u nifonn densi t y t hr ougho ut? And at the SMSA level, pe rhaps density is a proxy for ag e of dev elopm ent, city size, or some othe r facto r that affects travel behavior (i.e t ran s i t u se), as opposed t o the variabl e de nsity per sc. In parallel are prob l ems with the definition and m eas urem ent of segregation o f u ses." What is the definition of ''uses"? At whic h geo gra phical scale is separation or integration measured? Cervera (1996) found that the job-housing ( JH ) b alance a t the city l evel was not s i gnificantly associa t ed with the v ariation i n e xternal ( t o the c ommunity) commuti n g. Does this mean that land u se Integration as Rllfgen trooling fortOfll lrlttckerho H ECONotthwatt li t erature Synthe a it reflected in the JH ratio does not affect travel be havior? Or does it mean tha t land-u se i ntegration really does affect travel be havior-but tha t the m easure of land-use int eg r a tion is los t whe n the JH is seat e d a t the co mmunity-wide, as opposed to a n eig h borho od. level? Quality-of-life measures also pose a defmitional conundrum, as do other seemingly easi e r to-ascenain effects. Take, for instance, land consumpt ion. Although it a taut ology that d eve lopment consum es land, does a sing le-family home built o n a 50a c r e farm "consume" all of those 50 acres? I f i t c onsumes only a frac tion o n what basi s is that fraction appo ni o ned ? 4. Most critics of sprawl do not ucognize that it provides Sllbstanrial benefits to many households; hence, they do n o t take accou m of those benefi t s in their analyses. Several c r i tics o f sprawl, su c h as Kunstle r (1993). engage in rhetorical exagg erati o n to emphasi?.e their nega t i v e v i ews of spra wl.

have been undertaken. There is much discussion on sprawl but far fewer "facts" in the form of empirical, quantitative studies. The paucity of data is illustrated by the frequency of studies using "secondhand" or once removed information. A good example, as noted earlier, is the reanalysis of The Costs of Sprawl (RERC 1974) neighborhood and community prototypes some 20 to 30 years after the fact by Altshuler and Gomez-Ibanez (1993). Frank's 1989 review and reorganization of prior studies conducted over three decades in his Costs of Alternative Developmellt is yet another example. It is not that reanalysis or categorization per se is unimportanton the contrary, it can be quite va l uable. Rather, these studies point to the dearth of new empirical research on sprawl In a parallel vein is the tendency of the empirical research to be of a case study nature. Case studies provide valuable insight, but they are place-specific. The ability to generalize from them is quite limited. 6. Even when a quantitative analysis is attempted, the topical coverage is uneven. with much more attention paid to the "physical side" of irifrastn

The Costs ol $prowl-Revisited costs of leapfrog development, as noted below: Estimates probably overstate the added costs of leapfrog development in communities that expect continued growth and e\entual infill development on the vacant land. Compared with the planned communities, the sprawl communities contain substantially more vacant land that is improved or semi-improved by some road and utility access. Developing improved vacant Jand in the future presumably would cost less than developing unimproved land. If infill development is expected, then a portion of the added cosL' of leapfrogging eventually will be recouped-the costs of sprawl would be the costs of supplying some infrastrUcture in advance. of its eventual need and would be lower the more rapidly infill was expected.

Most commentators do not recogniu that two types of fragmented governance-those over land uses and over fiscal resources""""'re fundamental causes of many of the most widely al/acked results of sprawl. The main reason for this failing is tha t the analyses are not comprehensive enough. They focus on a few of the most obvious elements of spraw l and their consequences, rather than look at the entire relevant spectrum of elements and consequences. In addition, many observers hesitate to recommend changes in such fundamental American precepts as local control over land uses and separation of communities' fiscal resources. Several recent opponents of sprawl have recognized these connections Rutgn 8tool:ift8:1 Porson1 8rindr:rl

All c ritics of spra w l post ula t e con ditions (a) and (b), but many stop there. S ome proceed through conditions (c) and (d) as pan of their prescriptions for change. But few deal with condition (c) and almost none address conditions (f) and (g) which require the ability co measure both the costs and benefits of X and ics eliminati on. Yet realis cic s ocial analy sis requires meet ing all o bservable condi t ions. Even the m ost detailed quantitative analyses of sprawl 's costs tend to defme only one alternative to it, and compare the costs of future devel opment under just those two scen ari o s. That limitation is present, for exampl e in che series of analy ses directed by Robert W B urch ell (1992-1997) Spr awl i s a comp l e x p h en omenon co ntaining multiple future develop ment scenarios, no t just two. The refore, an adequate analys i s of sprawl's coscs compared to the costs of alternative forms of settl e ment must allow for more than two alternatives. Conversely, no analy sis ca n be useful if it presents dozens or hund reds of alterna t ives as e qually plaus ibl e. The best a pproach i s to defme t hree or more (but less Chan ten) major alternative settlement patterns an d to conduct multiple sensitivity analyses concerning key elements in each of those patterns-a very comprehensive and expensive process. II. The modeli ng of the analys i s is ofte n o v erl y simp l istic. T h e pe r ca pita engineering stud ies, for instance, literotur S}'nrhe1l s relate capitaVoperating costs linearly to lane-miles of roads and related factors. B u t the y h ave been criticized (rightly) for not i n corporating any informa tion on h ow c os t s can i n crease as thresholds o f d ensity increase, due to cong estion, pub lic safety needs, and the lik e. Incorporating this d i mension would increase the cost of compactnes s (Altshuler and Gomez-Ibanez 1993). Comparisons of sprawl and its aiiCrnatives als o criticized for not sufficiently ad dressing th e qualitative diffe .rences in hou sing amenity. Most ana lyses o versimpli f y the differen ces, alleging that the amenities are uniformly superio r for the detached units tha t characterize sprawl (Gordon and Richardson 1997a; Windso r 1979) The m o d eling of the ana l ysis is often simplisti c T h e limited depth of many ana l yses also renders the associati o n s tha t are drawn open t o q u esti o n I nadequate l y specified models or c ontrols are pan of the problem For instance, Newman and Kenworthy ( 1989a) applied only a single variable--urban density-to exp l ain automobile use, whereas other fac t ors are clearly involved These t w o authors, in analyzin g per c a p i t a automobile depen dence, used gasolin e consumption pe r capi ta as a proxy f o r automobile d e pendence. That equiva l ence is questionable. given the fact that many o th e r factors, such as gas prices and fuel efficiency chanlCteristies, affect per capita gasoline consumption.

analysis of 57 suburban employment centers did not control for the centers' transit availability or the quality of the pedestrian environment. Similarly, the Cambridge Systematics (1994) study of suburban work sites did not control for these sites' level of transit service. The difficulty in extrapolating the factors that influence these dynamics, and the difficulty in incorporating controls, are illustrated by the scholarly analyses of the effect of urban design. Many researchers are interested in whether nco-traditional design features (combined with a greater mix of uses) will result in travel behavior d ifferen t from the pattern observed in typical suburban development. There has been too little experience with these new types of suburban development to answer the question. Therefore, studies look at older neighborhoods that have a more pedestrian-friendly environment and a finer-grain mix of uses. But it is not clear whether behavior of long standing residents of older neighbor hoods accurately predicts the behavior of residents of new neighborhoods, who in all likelihood are more accustomed to using cars. Furthermore, the matched pairing of existing neighborhoods into "transit versus auto-{)riented" or "trad itional versus suburban" to test the effects of alternate design patterns on travel runs headlong into the practical difficulty of coming up with these pairings. Neighborhoods often don't slot neatly into those two polar categories. Even if this demarcation can he realized, variables other than overall design can affect the travel behavior equation-e.g., resident income, occupation, and age. Matched pairing is a diffic .ult exercise Uteroture Synrhesis to accomplish, since design preferences and household profiles often interrelate. The cross-sectional nature of many studies compound all these problems. Infrastructure costs rise as development is effected in a sprawl pattern; thus, sprawl gets tagged with the heightened capital expenses. Clearly, however, many other factors, from rising income levels to changing amenity levels, are also at work (Altshuler and Gomez-Ibanez 1993). Gordon, Richardson, and Jun ( 1991) link decreasing commuting times to the suburban deconcentration of job and residences that bas occurred at the same time. But does the former cause the latter. or is it merely coterminous? Similarly, Richardson and Gordon ( 1989) hypothesize that increases in nonwork trips are due to suburban decentralization. Again, this hypothesis could be true, or it could be unrelated to the spatial pattern and instead fostered by such influences as rising incomes, greater participation of women in the work force, and societal changes in leisure activities. In short, there is much peril attached to drawing conclusions from cross sectional research-precisely the kind o f research that characterizes many sprawl studies. The obverse of these defic.iencies must be employed to guide future research. As detailed elsewhere. sprawl and its alternatives must be explicitly and formally defmed. This effort can build from the literature. As noted in Chapter 2, some of the more recent studies on sprawl have differentiated i t from other types of development. In New Visions for Merropolitan America (1994) Anthony Downs defined sprawl as characterized by low-density, primarily 106 TRANSITCOOPUATIVHESEAACH PROGRAM (TCRP) HIO

The Costs of Sprowf....Revisitetl single family, development, with widespread reliance on filtering to provide low-income housing. Henry Richmond's Regionalism: Chicago as An American Region (1995), brought forth eight componeots of sprawl (lis t ed earlier). To Richmond's sound base. this literature review adds two more-( I) the commercial strip development described by Richard Moe ( 1995), and (2) a dependence on the filtering process to provide housing for low-income households as indicated by Downs (1994). Altogether, then, sprawl must be viewed as a form of urban development that contains most of the following ten elements: l. Low residential density 2. Unlimited outward extension of new development 3. Spatial segregation of different types of land uses through zoning regulations 4. Leapfrog development 5. No centrali7.ed ownersh.ip of land or planning of development 6. All transponation dominated by privately owned motor veh.icles 7. Fragmentation of governance authority over land uses between many local governments 8. Great variances in the fiscal capacity of local governments because the revenue-raising capabilities of each are strongly tied to the propeny values and economic activities occurring within their own borders 9. Widespread commercial strip development along major roadways 10. Major reliance upon the filtering or "trickle-down" process to provide housing for low-income households. Rutgen Brooldng1 Pon0t1a lrind::whoff ECONortkwe.-Utecotuce SynthasU T he above definition both builds from the literature on sprawl and stands in marked contrast to the studies that either do not define sprawl or else characterize it too simply and/or pejoratively-e.g., as a "lack of continuity in expansion" (Clawson 1962); a "low-density ribbon or leapfrog development" (Harvey and Clark 1965); or an "awkward spreading out of a community" (Abrams 1971). This literature review underscores the need for a comprehensive look at the effects of sprawl. To th.is end. a full menu of benefits as well as costs of the different development scenarios must be considered These benefits and cos t s must span the range of physical as well as social consequences. Funbermore, tbe ben efits and costs analysis must be tenitorially comp l ete-encompassing urban, suburban, and cxurban locations as well as developing and developed areas. The span of analysis must also be long enough to encompass the dynamic of sh.if ts over time, to show what happens, for example, t o areas initially leapfrogged under sprawl that are subsequently "filled in" by development. The analysis of and benefits must further incorporate the complexity of influences e.g the varyi11g threshold influences of density on capital-operating costs and the recognition that varying density thre sholds as well as other factors, affect travel. Moreover, caution must be exercised so as to not ascribe causality when the underlying evidence is merely cross-sectional. This literature review underscores the need for a comprehensive look at the effects of sprawl. I 09 TRANSIT COOPERATIVE RESEARCH PROGRAM (rCRP) H-10

II. ALLEGED NEGATIVE AND POSITIVE EFFECTS Linking Sprawl's Defi n ing Traits to its Alleged Impacts With a detailed analy sis of both the def inition of sprawl (Chapters I and 2) and its impacts (Chapters 2 and 3), it now becomes possible to link the two. Tables 12 and 13 evaluate the causal imponance of sprawl's ten defining traits in relation to its alleged 27 negative and 14 positive impacts. In each matrix, spraw l's defining traits are set fonh from left t o righ t as venical columns. The impacts are set fonh from top to bottom as horizontal rows, grou pe d into the five impact categories defined earlier Each cell in the mauix indicates a "sco re" that represents subjective judgments concerning the degree of influence of tbe defined trait (at the top of the column) on producing the indiv idual impact (at the lef t of the row). The "scores" are reflected by the follow ing symbols: + 2 Ind icates that the trait has a major influence in co using the alleged impact. + 1 Indicates that tho trait has a moderote or minor i nAuence in causing tho allogod impact. 0 I ndicates that tho has no inRuonce in causing tho alleged impact 2 Indicates that tho trait has a negative inRuence in causing the alleged impact; that is, the lends to reduce tho incid ence of tho impact Scores are summed at the bottom of each column to indicate the overall importance of a defming trait of sprawl in producing either positive or negative impacts. The order of importance of a trait (relative to other traits) reflects its surruncd importance and is also found at the bottom of each column. T h e Importance of Sprawl's Defining Traits Determining, in a rough mann er, the rela tive overall significance of a trait to its impacts can be achieved by examining the t otal scores of the trait in a matrix. For example the column label ed "lea pfrog development" in the negative impact matrix (se e Table 12) contains s ixteen "major influence ratings,'' five "moderate or minor influence ratings," and six "no influence" ratings. Th ese sum to a total of 37 for this trait and rank it the most significant of all sprawl's traits. Similar observations, summations, and rankings have been carried out for the other nine defining traits. Based on these calculations. three of sprawl's defining traits appear to be especially important in causing negative impacts. These are leapfrog developmem, low density, and unlimit ed outward extension, each of which score in the thir1ics for importance. Two others the spatial segregation of land uses and variance in local fiScal capacity-both scoring 10, seem to be of relatively weak significance. Among the remaining traits, widespread commerc ial strip development, highly fragmented land use governance. and no central ownership or planning (scoring in the low twenties or high teens), see m somewhat more significant than transport dominan ce by motor vehicles or reliance on filtering for low -i ncome bousing (both scoring 15). Negative Impacts of Sprawl Some individual sprawl traits, more so than others, negatively affect the five potential impact areas (public and private capital and operating costs transportation and travel costs, land/na t ural habitat II 0 TRANSIT COOPERATIVE RESEARCH PROORAM /TCRP/ H-10

preservation, quality of life, and social issues). For instance, leapfrog development, low density and unlimited outward extension n egatively affect public and private ca p ital and operating costs (becaus e res i de ntial development and nonresid ential d evel opm ent are distant from t h e c o r e and from eac h other, and thus are difficult to service) Three of sp r awl's defining trails appea r to be especially i mpo rtan t in ca u sing alleged negative impacts. These are leapfrog d eve l opment, low density, a n d u nlim ited outward exte n sio n. Following the above. trallsportation and travel costs are negativ ely impacted by the same three traits p l u s transport dominance by motor vehic les. and widespread strip development (again because develop mentis distant, spread out, and expensive to access) Basically similar to the nbove, land and nawral habitat preservati o n seems to be negativ e l y i m pac t ed by l eapfrog develop ment, unlimited outward ex t e nsion, and low-density traits of spraw l (which con sume significant amounts of land) yet by few others. Quality of life is negatively impacted by widespread commereial strip development and leapfrog development (due to the poor aesthetics of develo p ment and lack of sense of comm unity). Social condi t ions are negatively affected by spr awl's relia n ce on tiltering for housing, gr ea t variance in l oca l fiscal capac ity, and highly fragmented l and-use governance (due to lack of affordable housing, declining tax bases. and an absence of regional services). Obviously, the above are primarily inferences-but intuitively, these i nferences appear to s tand up Positive Impacts of Sprawl Th e analysis funher suggests (see Table 13) that the same three defining traits leapfrog developme nt, low density, and unlimited outwar d exte nsi o n-appear to be the most important in causing p ositive impa cts as well. The above three traits each score in the twentie s and rank I 2. and 3 respectively. Next in relative imponance is transportation dominance by private motor v ehicl es, followed by highly fragmented land -use governance, and no cen tral ownership and planning. Thes e range in score from a high of 1 3 to a low of 8. Leas t significant are the use of filtering for l owi ncome housing spatial ly segregated land u ses, great variance in fisc.al capacity. and widespread commer cial strip development. These range from a low of I to a high of 5. ln tenns of the positive effects of s prawl, public and privaJe capital and operating cosrs are lower (because they are not as complex and there is l ess demand on them) due to leapfrog and lowd e n s ity development, and unlimited outward extension. Transponation and travel cos r.t are lower (due to suburban-to-suburban commutes. reduced inner-suburb an congestion, and use of the aut omobile) as a result of the above three traits plus transport dominan ce b y motor vehicles, spatially segregated land uses, and widespread commercial strip development. Quality of life is better (residents like w h ere they Jive; communities h a v e l o wer crime mtes) again due to the above three traits ( leapfrog development, low density. unlimited o utward extension ) as well as to transport dominance by motor vehicles. Social conditions are better (more municipal diversity and choice) due t o highly fragmented land-use governance and no ce ntral ownership or planning. 113 TIIANSIT COOPERATIVE RESEARCH PROGRAM (TCRP) II-I 0

Th. Costs of Sprawi--ReviUr.d Clearly, there is a great deal of similarity between the positive and negative matrices of sprawl (Tables 12 and 1 3) as shown in Table 14. Paradoxically, the traits that seem key causes of many of sprawl's negative impacts also appear to be key causes of many of its positive impacts. This is true for such impact categories as public private capital and operating costs, transponation and travel costs, land and natural habitat preserva tion, and quality of life . The fact that sprawl can be simultaneously with both costs and benefits in relatively narrowly defined fields shows how complex t he phenomenon of sprawl is. The literature synthesis is summarized in Table 15. E vident from Table 15 is that the field tend s to be much more prolific on criticisms (27) leveled at sprawl rather than itS defense (14). There are about twice as many allegations of sprawl's negative impacts as there are of its positive impacts. With regard to recognition tha t "costs" oj development exist, there is more agree ment (general agreement and some agree ment categories combined) in the areas of public and private capital and opera t ing costs, quality of life, and social issues than there is in travel and transportation costs, and land/natural habitat preser vation. That these "costs" are linked specifically to sprawl (holding aside the issue of cau sality), there is more agreeme nt on pub lic and private capital and operating transporta t ion and travel costs, and social issues than there is on land/natural habitat preservation and quality of life. Thus. more impact categories identify themselves as being Rufgeu &rookinga Po110t11 ltitH:kthoH ECONorthwett lireroture Synthesis affected by development; fewer categories identify themselves as being impacted by a type of development that is akin to usprawt.' Areas of Future Research Tbe literature clearly signals areas of future researc h thrusts. On the "harder", more quantifiable, physicaVengineering side--that is, the issues of infrastructure, transportation, and land consumptionthe studies, to point to multiple appropriate measures to be cons i dered (e g., vehicle miles traveled [VMT) and congestion), as well as important relationships to be examined (e.g., density's effect on modal choice and travelt i me). However, these analyses must be brought together more defini tively and areas of outs t anding disagree ment from prior work (e g are com muting t imes shorter or longer under sprawl) must be examined empirically so that answers can be had. The field must attempt to fill in the lingering gaps in knowledge concerning the effect of d ev elopment patterns on operating cos t s, impact on productivity of farmland, and so on. As to sprawl's effect on the "softer less quantifiable, quality of life and social i ssues the challenge to current research is even more formidable. Here, interre l ationsh i ps are more complicated measurement is more elusive, and the association w ith development patt ern whether sprawl or otherwise--much m ore o b tuse. 117 TRANSIT COOPERATIVE RESEARCH PROGRAM (J'CRP) H l 0

Th Costs of Sprowf..-R.evisited I) The high-density planned community would be opt i mal with reference to all four key indicators examined : energy cost environmental impact, capital cost, and operating cost The low density spraw l community would be least desirable with reference to all four. 2) T he high-density planned community would require 44 percent less energy than the lo w -dens ity sprawl community. 3) The high-density p l anned community would generate 45 percent less air pollution. 4) The high-density planned commun ity would require a capital investment 44 percent Jess than the low-density sprawl community; the largest proportionate savings would be in road and utili ty construction, but the largest absolute saving would be in the cost of residen tia l construct ion itself 5) The operating cost of community services would be about II percent lower in the high density planned community than in the lowdensity spraw l community A classic in its field, The Costs of Sprawl has not failed to attract criticism. Perhaps the most glaring limitation is that its energy, pollution, and capital cost comparisons all require correction The authors assumed different space standards for the different types of dwelling units. The savings in capital and operating costs calculated in the report are mainly a function of the difference in size, not where these units are located or the density of their development. Furthermore the energy savings attributed in the report to high density development appear significantly overstated; and since the estimates of air Rutgers 8tOokingl Pors.ont &rindt.rhoff ECONortt.weJJ 12 5 Annototion:l pollution reduction was made a direct function of energy savings, these estimates must be deflated to a similar degree. Despite these qualifications, The Costs of Sprawl the close attention of those interested in an analysis of urban form. Although it is important to recognize the fragility of the main conclusions of The Costs of Sprawl, it is equally appropriate to recognize this report as a landmark from which most research on the consequences of urban form has branched. Souza, Paul. 1995. New Capital Costs of Sprawl, Ma.rtin County, Florida. Gainesville, Fl: University of Florida. This is a study of the capital requirements of growth in a developing county in South Florida. Souza assumes tha t Martin County's population will grow at a similar rate as the rest of South Aorida. He then calculates the density and distance-related costs of providing certain public infrastructure. Costs associated with providing roads, a potable water supply, and sanitary sewers within three different housing densities (3 5, and 10 units per acre) are assessed using Martin County specific unit costs and development assumptions. Souza then computes costs associated with connecting three sites at varying distances f r om the urban servtce area. Souza finds that the provision of infrastructure within the lowest density development is over I 00 percent more costly than the provision of infrastruc ture within the highest densiry development. He a lso finds that distance costs can not be separ.tted from density costs As distance from the center increases, density decreases. 7RANSIT COOPERATIVE RESEARCH PROGRAM (TCRP) H-10

Marginal Cost A11alysis of Growth Alternatives King County, IVaslington. Bethesda, MD: Tischler & Associates, Inc. This paper was prepared for the IGng County, Washington Growth Management Planning Council (GMPC) to evaluate options for future development. The analysis consists of three basic land-use scenari os with and without high capacity transit between planned urban centers, yielding five alternatives for study. Tbe study identifies the costs of new development for each alternative over a twenty-year projection period, estimating costs and revenues associated with growth for roads, transit, water and sewer utilities, and government administration. The study draws the following conclusions: The alternatives with more development in the urban centers and cities are more fiscally bene ficial when roads, utilities, and general fund activities are cons idered. The scenarios using eight centers generate higher net revenues for the general fund and utility districts than those with fourteen centers because Ruten 6rool:ingt Panon 8rinckerhoH ECONonh.,.,..ll 12 6 Annotation' the eight-center scenarios assume fewer new households in the unincorporated counties inside the urban growth area (UGA) than do the fourteen-center scenarios. The fourteen-center scenarios indicate net road costs which are II percent below those of the eight center scenarios. Road costs (especially rights-<>f-ways ) are higher for the eight-center scenarios because these alternatives include major increases in new households and jobs, which entail both the construction of new roads and purchases of rights-of-ways in the maturing urban centers. Windsor, Duane. 1979. "A Critique of The Costs of Sprawl." Journal of the American Planning Association 45, 2: (July ) 279-292. This article is a critical review of the RERC study, The Costs of Sprawl. The frrst part summarizes the findings from the RERC study. The author then critici?.es RERC for not disentangling density from other factors. Windsor criticizes RERC for using different size units for different densities i.e., smal.ler units for higher densities. Because smaller units have lower floor areas, they are less costly to build. This is a major reason why larger lowdensity, single-family units are considered more costly to build and to publicly service than highe r-density units. Total floor area is 44 percent lower in high -rise developments than single-family neighborhoods. Differences in housing costs and public capital largely parallel these floor area differences. Windsor recomputes the RERC analysis assuming all housing units are 1,200 square feet. This computation greatly reduces the housing and capital cost TRANSIT COOPERAfiVE RESEARCH PROGRAM (TCRP/ H-10

advantages of high density, though the advantages still exist. However, this approach is equally unrealistic. In reality higher density units are indeed smal l er, on average so RERC is not entirely wrong W indsor concludes that the only way to avoid the problem is to calc ulate results for both methods on a per sq uare foot basis and compare them Another criticism Windsor levels at the RERC study is that it assumes structure costs are highest for single-family homes, lower for high rise construction, and lowest for walk-up units. Windsor, in contrast, beli eves that high-rise units should have the highest costs per square foot. He also takes issue with RERC s assumption that developers have to contribute more land to the public sector under single-family development than under high-rise development. RERC assumes tha t clustering in higher density patterns results in savings of vacant land. But, Windsor argues that if the model assumed that a given amount of land is developed at different densities tbe total population accommodated on the land could vary Some abili t y to account for saved land when h ave more land immedia t ely around them than permitted by existing zoning should have been developed. The author also criticizes RERC for: "the underlying assumption t hat cost minimization is an appropriate principle for planning and development ... Cost minimization is not a planning pri nciple unless benefits are constant." Since RERC ignores the benefit side, its conclusions of reduced costs ignore the reduced benefits. However, the author thinks it is no t necessary to measure benefits. He claims the prevalence of low-density settlements reflects the benefits t o consumers: "Consumers choose to live at high densities only lutg.-a lroollillg" Por10n-1 8ril'lckerhoH 12 7 Annotolions where land costs are very higb, as in central cities. Where land costs are lower, as in suburbs, they prefer low density environments The author claims that suburbs res i st high density on several grounds, not just costs.

( 291) By ignoring these nuances, says Windsor RERC "does not properly evaluate the relative economic efficiency of alternative development patterns." (291) York, Marie L 1 989.

"Review of The Costs of Sprawl," Journal of the American Planning Associo.tion 43, 2: 207-209. This short anicle reviews the RERC report and was published about two years afte r the report. The review is so clear and so well done that it chang ed forever the way the Costs of Sprawl report was viewed. For purposes of simplicity, Altshuler focuses on the two extreme cases analyzed by RERChigb-density multifamily housing and low-density single -famil y housing. He begins by summarizing the major findings of the RERC study. He then asks three questions: (I) Have the results of the theoretical analysis been calibrated against actual community experiences? (2) Does the report itself fully support the conclusions stated in its summary? and (3) Are the reported advantages of high-density ove r low density development clearly differentiated as to reason? His answer to all three questions i s N o"! One key issue Altshuler raises is wheth er density per se affects the demand for community services. RERC explicitly assumes that it does not, but Altshuler challenges that assumpt ion. Low-density areas often have n o sidewalks; they have above-ground utility lines, and infrequent street lights when measured against high-dens ity areas The demand for public safety services is also likely to be lower in low-density development. Further, RERC does not include any estimates of mass transi t spending in its study, though such spending would surely be higher in high-density communities that rely more on mass transit. Therefore, Altshuler maintains high-density settlements are likely to have higher TRANSff COOPERAnVE RESEARCH PROGRAM (TCRP) HlO

The Cosh of Sprowi-RevisiteJ community service costs than low density ones, which would offs et many of the savings projected for the latter types of seUiements. According to RERC, the savings for high-density liv ing versus low-density living are only $238 per year in operating costs, for a density rise from 3.5 to 19. 0 units per acre plus more intensive planning. Four-fifth s of the savings are attributed to den s ity alone. Altshuler believes, given the omissions mentioned above, that this small amount would vanish if the analysis were done correctly He also makes the point, which Windsor later picks up on, that dwelling units in the high-density settlement are 34 percent smaller than those in the low density settlement, and this accounts for a large part of their differences in capital and energy costs. Five-sixths of the heating and air conditioning savings in high-density developmem is attributable tO smaller housing unit sizes. RERC funher assumes that average annual travel per household in high density dev e lopments is about 9,891 miles versus 19.673 miles per household in low-density developments. Generally. only local trips vary by density but RERC fallaciously attributes cost savings to the entire travel mileage. According to Altshuler, correcting this error eliminates four fifths of the claimed savings in auto energy consumption. With proper analysis, the total energy savings of high-density versus low-density development is about 3 percent, of which only l percent is attributable to density alone. Another issue Altshuler addresses is whether higher residential density leads to higher density in other types of land uses. He thinks not: "The case that low-density living is a highly expensive luxury remains to be made" (209). Nonetheless, the autho r commends RERC for having putting forth a systematic analysis that can serve as a starting point for other studies. Altshuler, Alan A., and Jose A. Gomez-Ibanez. 1993. Regulation for Revenue: The Political Economy of Land Use Exactions. Washington, DC: Brookings Institution. The central i ssues and themes of this text relate to government-mandated exactions paid by real estate developers. Exaction s may be in-kind or involve monetary outlays. The legal theory underlying development exactions i s that governments, having reasonably determined that cenain public needs are "at tributable" to new development, may require that their costs be "i nternalized as part of the develop ment process. A key premise of the argument for exactions is that land development is a major cause of escalating local infrastructure demands and costs. This study looks at the costs of growth in built up communities. Alternative estimates of revenues and expenditures for the city of San Francisco are discussed, as are approaches for allocating public expenditures for growth among county businesses and residents in Montgomery County.

First, major categories of public expenditures (education, health and welfare, and safety) and public revenues (property taxes, state funds, and other local taxes) are identified, based on the county's annual budget.

Buchanan, Shepard C. and Bruce A. Weber. 1982. "Growth and Residential Property Taxes: A Model for Estimating Direct and Indirect Population Impacts.'' !.And Economics 58, 3 (August): 325-337. Buchanan and Weber's analysis is an attempt to detennine the extent to which population growth affects single-family residential property taxes, and how these effects are transmitted. To answer these questions, the authors examine both tax rates and assessed values of properties in Oregon, and the possible influence of increased population on each of these variables. Among other procedures, they study intermediate variables such as age of housing stock, personal income and population density. The authors find that up until 1979, increases in new single-family homes apparently both directly increased average homeowner assessments and indirectly increased tax rates on all properties. In 1979, however, the Oregon legislature enacted a taX relief program under which the average rates of increase in assessed valuation of both residential property and all other property on a statewide basis were limited to a maximum 5 percent per year. After this change was enacted, assessments and tax rates slowed in their rate of increase The costs of servicing new properties could no longer be "exported" to old properties beyond a fixed percentage per year. The authors suggest that similar legislation be enacted in other states where there is a quest for homeowner property tax relief. They assert that the model they developed for local governments in Oregon is generalizable to other states with similar tax systems.

This report analyzes the impact of alternative municipal service pricing policies on urban structure and on a community s financial position. A pricing policy is a method of allocating the cost of a service to one sector or another of the community (e.g., new residents, existing residents, the entire community). In this report, primary attention is paid to pricing policies for the capital infrastructure required to service new development. The pricing structures estimated in the report are developed using actual data from San Jose and Gilroy, California. San Jose is a fairly large city that has already experienced fairly rapid growth; Gilroy is a city that could potentially undergo explosive growth. Both are believed by the authors to be prototypical of a number of American cities. This analysis finds that pricing policies allocated to the largest base of payees has the least overall negative effect on the economy of the community. Downing, Paul, ed. 1977.

The Cosfa of Sprowi-Revjsifed A user charge is an explicit price on the consumption of a public service. In addition to being a source of revenue, user charges are also a direct measure of taxpayers' willingness to pay for the services pcovi ded by local government. A user charge makes the payment explicit and directly associated with the public service that is being delivered. I t gives the taxpayer a better understanding of what the choic e s are, enabling a more intelligent decision regarding the array of goods pcovided by local government. In addition, the user charge performs the function of price. It rations demand, according to who values the service most highly The first section of this book presents the r ationale for developing new sources of revenue for local government. It identifies the possible scope of user charges as a means of filling this demand, and presents a detailed examination of how a user charge is designed and calculated The second section presents an analysis of spatial variation in the costs of providing public services. The third section is concerned with institutional systems and their effects on the financing and supply of services. The founh section argues that while location may not affect costs, political bodies are willing to account for cost differences in the way they assign user charges.

Impacts of Devewpmmt on DuPage County Property Taxes. DuPage County, IL: DuPage County Regional Planning Commission. Five years ago, a brouhaha emerged in the Chicago area involving the cost of nonresidential uses. Debate in DuPage Annotations County centered on whether or not commercial uses paid for themselves A number of expens subsequently gathered to evaluate the findings of the DuPagc County Planning Commission's study, Impacts of Development on DuPage Co1111ty Property Taxes. A regression analysis by DuPage County inferred a strong relationship between nonresidential development and property 1(1)( increases. Although preservationists leaped to defend these findings, others pointed to the weaknesses of the study The most convincing of the critiques took a position in the middle-pointing out that some evidence backed up the fmdings of DuPage County, but the evidence was not nearly as strong as had been presented in the report. The DuPage County report is not a classic fiscal impact analy s is, but rather a regression equation in logarithmic form. The dependent variable is total propeny taxes levied; independent variables include change in nonresidential fmns change in ratio of nonresidential -to residential equalized valuation, median residential propeny tax levy, and the ratio of taxes to the total municipal equalized assessed valuation. Some critics of the analysis believed both sides of the regression equation formed an identity whose intercorrelation prevented solution. Some thought the research design should undergo significant alteration; others thought both dependent and independent variables should be recast. DuPage County, however, continued to defend both the analysis and its results. In reality, the analysis must be put into a fiscal impact frame wherein all costs can be compared to all revenues.

services, the relative levels of tax and nontax revenue, the presence of de.ficient or excess service capacities. and the effects of other land uses in similar situations should be viewed. A number of studies with similar conclusions about nonresidential growth's impact on property taxes have been documented. Most results can be traced to the nonaccountability of elected/appointed officials, which in tum Jed to significant service increases for primarily nonresidential properties. The DuPage study points out that nonresidential development and its associated surplus fiscal revenues could improve service quality and quantity i n a community. However it may also increase local expenditures. Without knowing the type and quantity of public services produced before and after the nonresidential development is put in place, no judgment can be made about nonresidential development and future tax rates. Logan, John, and Mark Schneider. 1981. ''Suburban Municipal Expenditures: The Effects of Business Activity, Functional Responsibility, and Regional Context.'' Policy Studies Journal 9: 1039-50. The authors set out to explain the variations in the level of suburban government spending. They first summarize existing explanatory models, which stress either local stratification and discrimination, the structure of local decision making, ecological position, or public choice. Th ese models suggest varying hypotheses about which suburbs spend more and which less. Logan and Schneider then evaluate each of the alternative models and propose major directions for further research. Annotations The authors conclude tha t each model has its strengths and certain hypotheses from each is supported by the data. Certain variables stand out, however, as having particularly strong explanatory power in all models. The strongest, in terms of determining suburban expenditures, is economic function Regardless of any other differences among communities, suburbs with strong employment bases spend more than thos e with weak employment bases Of nearly equal importance is the set of service responsibilities that a suburban municipality assumes. This finding may take historical inquiry to fully explain Finally, differences in SMSA structure are shown to explain part of the expenditure variation, although no simple reason is given for this influence. Instead, the authors call for additional research to be directed explaining what kinds of economic, hi storical, political, or social situations cause the differences in suburban expenditures detected in this study. 3.

The author's general conclusion is that environmentally sensitive land use planning n eed not have a detrimental effect on real estate values, economic vitality, or the local tax base. Rather. tbe opposite is often true. The auth ors close on the optimistic note that the lessons contained in the studies may help Greater Yellowstone (near Bozeman, Montana) communities successfully manage rapid growth and change as they choose their own futures Schwartz, Seymour David E. Hansen, and Richard Green. 1981. "Suburban Growth Controls and the Price of New Housing." Journal of Environmental Economics and Management 8 (December): 303320. In this paper, the authors study the effects of suburban growth control programs upon the price of new housing. The programs that limit growth employ a variety of devices, including phased zoning, reduced development densities and increased development charges Some programs take an even more direct approach, by setting restrictions on the number of housing units permitted, or by imposing population or housing unit caps. The authors then analyze the e.ffects of perhaps the most direct form of control: the housing quota of Petaluma, California. To estimate price effects, the authors compare price changes of new single. family housing in Petaluma between Rutgers Brooking 8-tineblilolf ECONorthwe., 136 Annototions 1969 and 1977 (after the quota was enacted) to tbe price changes in two nearby communities The authors limit the analysis to new housing because it provides a relatively consistent basis for evaluation. The study's results suggest that Petaluma's growth control program was responsible for an increase in housing prices. Because of the complexity of the issue, however, a totally unambiguous finding is not possible. The authors art' more confident when describing the effect of growth controls on the quality of construction. Here they find evidence that higher construction quality and prices are anributable to grow th controls. The authors close by calling for additional research to analyze the of growth controls on housing price. Schwartz, Seymour I., Peter M. Zorn, and David E. Hansen 1989.

This is explained by the fact that the decrease in the quality of new housing may have encouraged households desiring big her quality (larger) housing to tum to the older housing market, resulting in an increase in the demand for higher qualiry older homes T he authors conclude that price mitigat i ng measures are only partially successful in reducing the price e.ffects of growth controls, since they mostly shift the impacts of growth controls fl'()m the new to the old housing market. 4. URBAN FORM AND SPRAWL Ladd, Helen, and William Wheaton. 1991. "Causes and Consequences of the Changing Urban Form." Regional Science and Urban Economics (21): 157-162. The papers compiled in this work were initially presented at a conference on the Causes arrd Consequences of tire Changirrg Urban Fom. October 1990, run under the auspices of the Lincoln Institute of Land Policy. The goal of the conference was to bring together empirical, theoretical, and policy oriented economists to improve the understanding of the nature, causes, and implications of pol ycentrism in metropolitan areas. Recently. older. traditionally monocentric cities, such as Boston and Chicago. have developed significant suburban subcenters. Other newe r cities, such as Phoenix, Dallas, and Los Angeles are perceived as lacking in any sense of "centrali!y ." Two of the papers in this collection provide on the nature and function of e mploym ent subcemers and decentralization; two d e velop and test empirical models that specifically include elements of polycentrism. One paper prov ides a new theory of subcenter fonnation in the context of a dynamic model ; and two more examine various implica t ions of changing urban fonn for labor markets. McKee, David L. and Gerald H. Smith. 1972. "Environmental Diseconomies in Suburban Expansion." Tire American Journal of Economics and Sociology 31 2: 181-88. In this paper, the authors set out to isolate and analyze the components of suburban sprawl. Causes of spraw l are discussed, and an attempt is made to specify the economic effects sprawl has on urban areas, people, and the economy. The authors intention is 10 develop suitable policy recommendations for dealing with sprawl. The authors conclude that spraw l appears to be the result of strong market forces. and that solutions to the problem may be beyond the abiliti e s of public policy makers to solve. They call for more govemment intervent ion, especially at the local level. and for action on the part of regional planning agencies. To date, these institutions have not been able to deal adequately with the problem, because of overlapping jurisdictions and ot h er political cons ide rations. The authors further call for greater cooperation and sharing of resources at all leve ls of government to find solutions to suburban sprawl. TRANSIT COOPERATIVE RESEARCH PROGRAM (TCRP) fl. I 0

Mills, David E. 1981. "Growth Speculation and Sprawl in a Monocentric City.'' Journal of Urban Economics 10: 201-226. Mills presents an economic theory of sprawl in a growing, monocentric city. He posits that where decision makers have perfect knowledge, leapfrog development and discontinuous land rent functions may occur and be efficient in both an ex post and ex-ante sense. Where the extent of future growth is uncertain, decision makers become speculators, and the spatial pattern of development is more complicated Ex post inefficiency generally occurs In the context of Mill's formal monocentric-city model, three land-use patterns qualify as examples of sprawl. Leapfrog development occurs when a von Thuncn ring of undeveloped land separa tes rings of developed land This form of sprawl involves radical discontinuity. Scattered development, the second form of sprawl, occurs when there are annuli with both developed (homogeneously) and undeveloped land in them. Mixed developmelll occurs when there are annuli with more than one developed use. Scattered development and mixed development forms of sprawl involve circumferential discontinuity. Mills provides theoretical explanations for each form of sprawl. L eapfrog development can be explained by inter temporal planning on the part of decision makers who anticipate future growth with certainty. The essential idea here is similar to the notion put forth by Ohls and Pines (1975), that is, that land inside of the urban fringe is sometimes withheld from early development and preserved for more remunerative future options. Theoretical explanations for scattered and mixed development forms indicate that decision makers are Annotations uncertain about future growth and make speculative decisions. Several criticisms of sprawl are cited and addressed with evidence generated from the monocentric city model constructed for this analysis. Obis, James C., and David Pines. 1975. "Discontinuous Urban Development and Economic Efficie-ncy." Land Econ.omics 3 (August): 224-234. Many observers argue that discontinuous development (wherein land that is closer to urban centers is skipped over in favor of land further away) is inefficient for several reasons. First, this development pattern fails to make use of the most accessible land. Second, the expense of providing public services, such as roads and sewage systems, to new development is high. In contradiction, Obis and Pines argue that discontinuous development may be desirable and efficient in certain cases For instance, the development of retail and commercial services near the urban fr i nge must often wait for the maturation of critical scale. In rapidly expanding urban areas, contexts arise in which it may be efficient to skip over land for a period of time in order to reserve it for commercial uses after market scale mcreases. This strategy has been implemented in some planned communities. In Columbia, Maryland, for example, the planners of this "new town" explicitly reserved vacant land in residential areas for the development of shopping clusters in the future-after increased residential densities make such shopping enterprises economical ly feasible.

Rossetti, M. A., and B. S. Eversole. 1993. Journey to Work Trends in the United States and Its Major Metropolitan Areas, /960. Washington, DC: U.S. Department of Transportation. The authors compare mean commuting times in 1980 and 1990 for the 39 metropolitan areas with populations in excess of one million in 1990. They find that commuting times increased in 35 of the metropotitan areas, and that the increases ranged from 0.47 percent in Philadelphia to 13.69 percent in San Diego. All four of the metropolitan areas with commuting time increases of more than 10 percent are Sunbelt cities: Los Angeles, San Diego, Sacramento, and Orlando. The only cities where commuting time declined are New York (.70 percen t ) Pittsburgh ( .05 percent), New Orleans ( -0. 57 percent), and Salt Lake City ( .92 percent). 2. THE EFFECTS m; DENSITY ON TRAVEL CHOICES 2.1 Simulations Downs, Anthony. 1992 Stuck in Traffu:: Coping with Peak Hour Congestion. Washington, DC: Brookings Institution; and Cambridge, MA: Lincoln Institute of Land Policy. Downs develops a hypothetical urban area model to test the extent to which changes in the location and density of development would change average commuting distances The basic model uses values for the proportion of jobs in the CBD, central city, suburbs, and exurbs, and commuting distances similar to the averages for large metropolitan areas. Different densities are created by varying the size of the suburbs and exurbs (and adjusting the proportion of population and jobs in each area as needed to match the size). Brooking Porl(H'It lrindc:moR 14 I The study shows that the density of growth at the urban fringe has a significant impact on commuting distances; a move from very low to medium densities has the greatest impact. Increasing ex urban densities from 886 persons per square mile to 2,800 reduces commuting distances by 8 percent. An increase from 886 persons to 4,363 persons per square miles decreases commuting trip lengths by 14 percent. Beyond that, large increases in density shorten trips by only a smaJJ amount. Metro. 1994. Region 2040 Recom mended Alternative Decision Kit. Portland OR. This analysis of alternative urban forms of growth for the Portland, Oregon metropolitan area shows that more concentrated development, in conjunction with expansion of transit service, reduces vehicle mites of travel and use of the automobile. This study uses one of the most advanced travel demand models in the United States to simulate transportation outcomes. It determines that under continued current development patterns, the urban area would have to expand by more than half of its current size over the next 50 years. The study also tests three different scenarios that concentrate various amounts of growth in transit corridors, centers, and in neighboring cities. In the "Growing Our' scenario, a larger share of single-family housing is built than the region has at present, with more than one-fourth of future growth placed outside the current urban growth boundary. The "Growing Up" scenario keeps all future growth inside the urban growth boundary by increasing densities and building a larger share of multifamily housing. The "Neighboring Cities" scenario moves about one-third TRANSIT COOPERATIVE RESEARCH PROGRAM (TCRP) H-l 0

7he Cosh ol of the expected growth to other cities within commuting distance of the urban area. Not surprisingly. the highly concentrated development of the "Growing Up" scenario produces the highest transit use (6 percent of all trips) and the greatest reduction in VMf over base case levels (16.7 percent). The more disper s ed patterns, while consuming more land, bave lower levels of congest ion. Despite the results of thi s study, the ability to change travel behavior is limited, because much of the capital in frastructu re tha t will serve the built environment for the next 50 years is already in place. Some of the study's other proposed changes in the way the regions develop may also not be feasible to undertake for political and economic reasons. 2.2 Empirical Studies Cervero, Robert. I991b. "Land Use and Travel at Suburban Activi ty Centers.'' Transportalion Quarurly 45, 4: 479-491. This article analyzes the effects of den sity, land-use mix, and parking characteristics on commuting behavior in suburban activity centers. The study uses data from 83 randomly selected buildings in six suburban activity centers, collected as part of a project called Travel Characteristics of Large Scale Suburban Activity Centers, for the National Cooperative Highway Research Program The strongest relat ionship evidenced in the study was between density (measured as the height of each building) and transit use.

Using buildings as the unit of analysis in this study poses some problems. For example, the study fails to consider other center characteristics that may play important roles in determining commuting behavior, such as distances between buildings and opportunities to shop and conduct personal business at other locations within the center. Cervero, Robert, and Kara Kockelman. 1996. "Travel Demand and the 3Ds: Density, Diversity, and Design." Transportfllion Research Digest 2, 3:199. The authors claim that a host of urban design philosophies new urbanism, transit -oriented development. traditional town planning-have gained popularity in recent years as ways of shaping travel demand. All share three common transportation objectives: (I) reduce the number of motorized trips; (2) of t rips that are produced, increase the share that are non-mOtorized; and (3) o f the motorized trips that are produced, reduce travel distances and increase vehicle occupancy levels. An expected outcome of weaning people from their cars, proponents hope, will be a lessening of the negative consequences of an automobile-oriented society namely, air poll u tion, fossil fuel consumption, and class and social segregation. Cervero and Kockelman describe bow new urbanists. nco-traditional ists, and other reform minded designers argue for changing three dimensions, or the 3Ds, of the built environment-density, diversity, and design-to achieve these objectives. While the effects of density TRANSIT COOPERATIVE RESEARCH PROGRAM (TCRP) H-10

PAGE 151

The Cosh ol Sprowi-RMsited on travel demand have been acknowledged, the effects of diversity and design have just as long been ignored. This paper examines the connection between the 3Ds of the built environment and travel demand. It tries to son through the relative influences of these three dimensions after controlling for other variables, such as travelers' demographic characteristics. It dces this by applying the technique of factor analysis to gauge the relative influence of each dimension as well as their collective impacts The research findings of this paper lend some degree of credibility to the claims of new urbanists and others that compact, mixed use, pedestrian friendly designs can r educe vehicle trips, vehicle miles traveled (VMT) per capita, and motorized travel. The research suggests that the effects of the Bay Area's built environment on travel demand were modest to moderate at best. Densities exerted the strongest infiuence on personal business trips. Additionally, residential neighborhoods that were spatially accessible to commercial activities, reflected by an accessibility index variable, tended to average appreciably less VMT per household. Diversity also had a modest impact on travel demand, a lthough where it was significant its influences was somewhat stronger than that of density. Having retail activities within neighborhoods was most closely associated with mode choice for work trips. Further, the dimension of walldng quality was generally moderately associated with travel demand Finally, several specific design elements of the built environment seemed to be particularly relevant to non-work trip-maldng. Notably, neighborhoods with high s hares of fourway intersections, as a proxy for grid iron street patterns and limited on-street parking abutting commercial establishments, tended to average Jess Annota tions single-occupant vehicular travel for nonwork purposes. The researchers believe that higher densities, diverse land uses, and pedestrian-friendly designs must co exist to a certain degree if meaningful transportation benefits are to accrue. Having nice sidewalks, attractive landscaping, and other pedestrian amenities in a low-density, residential only neighborhood is unlikely to prompt many residents to walk to shops and stores. However, the synergy of the 3Ds in combination is likely to yield more appreciable impacts. Dunphy, R. T., and K. M. Fisher. 1994. Transportation, Congestion and Densizy: New Insights. Paper presented at the 73rd Annual Meeting of the Transportation Research Board, Washington, DC: January. Using data on urbanized areas from Highwa y Statistics, 1990, the authors investigate the rela tionships (using graphs) between density and vehicle miles of tmvel and travel use. They find some correlation between urbanized area population density and transit use (26 percent) but little correlation between vehicle miles of travel and density (8 percent) However, using data from the 1990 Nationwide Personal Transportation Survey, the authors find that people in denser areas make nearly the same number of daily trips as people at lower densities, but they drive less. At most den sities the average number of person trips per day is just below 4.0; only at 30,000 persons/square mile or more do trip numbers dip to 3.4 trips per day. However, the average number of trips by car drops from about 3.5 at densities below 30,000 persons/square mile to 1.9 at 30,000 persons/square mile. People living at higher densities drive less because both transit and 7RANSfr COOPERA11VE RESEARCH PROGRAM (TCRP) H -10

walking/biking are more viable options. The authors, however, find a strong correlation between density and life cycle stage. T hey contend that demographics may be more of a contributing factor to differences in travel behavior than density. This study is descriptive, suggesting relationships that need further analysis with multivariate techniques to sort out the relative effects of household charac t eristics versus land-use density. The data analyzed in this study are also aggregate, oomparing whole regions rather than specific places within regions where people live and work. Dzur ik, Andrew. 1993. ''Transportation Costs of Urban Sprawl: A Review of the Literature." Stale Transportation Policy lniliatie. Center for Urban Transporta tion Re search. November. This article cites nine important studies that deal with transportation oosts and sprawl, including the classic RERC 17e Costs of Sprawl study (1974a) reviews by Altshuler (I 977) and Windsor (1979), and several others The first part of the article cites a I 965 study-"The Nature and Economics of Urban Sprawl" by Harvey and Clark-that defined three characteristics of sprawl, low den s ity, ribbon, and leapfrog development Automobile use was also viewed as the catalyst for urban sprawl. John Kain (1967) argued, however, that any savings from developing high density areas may be offset by higher construction costs per unit. RERC's report is cited extensively It estimated that a low-density sprawl community would require more than six times the amount of minor streets than a planned high-density community. Only road lengt h costs were considered as direct costs in the analysis of transAnnotations portation variations among these com munities. However, two indirect costs were also considered: travel time and air pollution. The RERC report assumed twice as much VMT in a low-density community, which accounted for a large difference in such costs. Dzurik' s article then cites Altshuler's criticisms of the RERC report. Altshuler's book The Urban Transportation System (1979) argues that the American public has strong preferences for auto transportation and low-density settlements. Therefore, Americans will refuse to live in densities high enough to bring about any changes in the problems associated with sprawl, which he believes have been exaggerated anyway. Bowler completed a study in I 977 that show ed that "user -oper ated transporta tion" accounted for about one se v enth of consumer spending, a proportion that stayed roughly constant from 1950 through I 973. He argues that suburban living results in higher use of energy and land resources for transportation than higher-density living. When the urban environment is modeled as polycentric, however, the percentage of subu rban dwellers who increase their travel distances for journeys to wor k no longer continues to rise, since work places also beeome decentralized. Yet many models assume that rising commuting costs are a major transportation oost of suburbanization. Gordon also argues that because work trips are declining as a percentage of all trips, the relative importance of accessibility to workplaces as a motive for choosing places to work and places to live is falling Gordon and Richardson argue that decentralization is an antidote to traffic congestion beeause it scatters both origin and destination TRANSIT COOPERATIVE RESEARCH PROGRAM (TCRP) H-10

BART failed to replace the auto as the preferred means of commuting in the Bay Area, in spite of its enormous cost. Where light rail systems have been created, cities have experienced small gains in public transit ridership over pure bus systems, but they have also incurred ma jor cost increas es Light rail tends to replace bus travel more than auto tr'avel. Dzurik reviews the argument over com pac t development. One advantage compact development is supposed to have over sprawl is that it uses the excess capacity in existing infrastructures, rather t han create a need to build new infrastructures. This was a major source of the economies found in the New Jersey sprawl studies. But such savings do not a lways materialize. Dzurik discusses how much subsidy from local governments goes into highways and mass transit. In Mil waukee, Wiseonsin, for example, he points out, the loca l burden of highway costs equals 59 percent of the local property tax levy. Because user fees do not pay the entire cost of auto travel, more sprawl occurs than would otherwise take place. Dzurik's study claims that the transportation costs associated with urban sprawl have not been studied in the appropriate quantitative terms. Therefore most questions about this issue are s till unanswered.

Frank, L. D., and Gary Pivo. 1994 The Relationship Between Land Use and Travel Behavior in the Puget Sound Region. WA-RD 351.1. Olympia, WA: Washington Stat< Department of Transportation .. The authors use data from the 1989 Transporzarion Panel Survey for the central Puget Sound region, along witb household characteristics from the 1990 Census, employment data from the state employment agency, and land-use data from the county assessor to identify the factors tha t affect travel behavior They find that density, mix, and jobs/housing balance are all related to travel behavior, with emp loyment density and jobs/housing balance having the strongest relationships. At higher densities, trips are shorter but take more time. More trips are made using alternatives to the single-occupant vehicle. As land -use mix increases, trip distances, times, and auto -mode shares decrease. As jobs and housing become more balanced, trip distances and travel times go down. The relationships between density and mode split are not lin ear The authors identify thresholds at which there is a substantial increase in transit use. These thresholds are 50-75 employees and 9-13 persons per gross acre for work trips, and 75 employees and 18 persons per gross acre for shopping trips. The use of carpooling however, seems unrelated to urban densities or other land-use attributes. The study controls for household characteristics, such as income and vehicle availability.

Gordon, Peter, A. Kumar, and Harry W. Richardson. 1989. "The Influence of Metropolitan Spatial Structure on C o mmuting Time.'' Journal of Urban Economics, 26: 138-151. Tbe authors combine data on residential and employment densities (residents or workers per acre of land zoned for that p urpose ) for 82 SMSAs from twelve states (from the U.S. Geological Survey LANDSAT file) with census data to id entify factors that influence commuting times by auto and transit. Their research finds that lower residential densities are associated with shorter commuting times both by car and by transit. For auto trips. concentration of industrial employment l eads to shorter travel times, whereas concentration of commercial employment i ncreases trip times The clustering of manufacturing produces economies in driving, but the clustering of commercial activities (such as in the CBD) produces congestion that reduces times Other variables (land area, income, economic structure) have the expected positive or negative influences, and the equations are fairly robust, explaining 61 to 87 percent of the variability in mean travel times. As a result, the authors conclude that polycentric or dispersed spatial reduce commuting times. The authors' use of SMSAs as the unit of analysis, however. raises questions about what density means. No SMSA has uniform density throughout. Perhaps lower regional density is a proxy for age of development, city size, or some other factor that influences transit use. Brooking Pon

The Com of Sprawl-Revisited doub le, vehicle miles of travel decline by 16 percent, controlling for such factors as transit service intensities and vehicle ownership. Better access to transit also reduces vehicle miles of travel. Shopping opportunities and the pedestrian environment, on the other hand, are not statistically significant in explaining travel behavior. Although, income is controlled in this study, residents could still vary by number of children, number of workers, or other characteristics that influence travel behavior. While, this cross sectional analysis shows a rela tionship between density and automotive use in existing communities it does not demonstrate that if lowdensity communities became denser fewer trip s would be made by automobile. Newman, Peter W. G., and Jeffrey R. Kenworthy. 1989a. Cities and AuU>mobile Dependence: An International Sourcebook. Brookfield, VT: Gower Publishing. Newman and Kenworthy assemble a set of data on the transponation and land use characteristics of ten large U.S. cities, five Australian, twelve Western Europe, three Asian, one Canadian, and one Russian city for the period 1950 to 1980 Using gasoline consumption per capita as the primary measure of automobile dependence (other measures sucb as transit mode share are highly correlated with this measure), they identify the rel ationship between auto mobile dependence and urban density. Low densities are assoc iated with high automobile dependence, and high densities with less dependence on the automobile This relationship ho lds for regions as a whole, for inner areas (pre World War II parts of the cit ies). and for Annotation' outer areas As a result, the authors conclude tbat more compact cities would reduce automobile use. Reviewers, however, have questioned the validity of using gasoline consumption as the measure of automobile dependence, noting that many factors, sucb as gas prices and fleet characteristics, influence gasoli ne consumption. Newman and Kenworthy s analysis of automobile dependence also fails to make full use of tbe data collected, employing only a single variable-urban density-to ex plain automobile use, when other factors are clearly involved. As a result, the role of density may be overstated Parsons Brinckerhoff Quade and Doug las. 1996b. "Commuter and Light Rail Corridors: The Land Use Connection In Transit and Urban Form, VoL I.

The study finds !hat residential densities have a significant influence on light rail boardings. A 10 percent increase in residential density within two miles of stations increases station area boardings by 5.9 percent, holding constant other factors affecting ridership, such as income. Residential densities matter less for commuter rail boardings. Commuter rail is a high fare mode of travel, and many of the high-income riders come from low-density suburban areas some distance from the city center. Both the size and density of the CBD influence light rail ridership. A 10 percent increase in CBD employment density raises light rail hoardings per station by about 4 0 percent, holding constant the number of CBD employees, the residential density of stations, and other factors affecting ridership For commuter rail a 10 percent increase in CBD employment densities increases station hoardings outside the CBD by 7.1 percent The study concludes that light rail is most cost-e f fective and efficiem in the cities with larger CBDs and denser corridors. Commuter rail works best with dense CBDs Other factors within the control of transit agencies, such as the availability of feeder bus serv i ce and park-and-ride lots, also influence ridersh i p and costs.

Parsons BrinckerhoiT Quade & Douglas. 1997 "TCRP Project H-13A-Draft Report: Consequences or the Interstate Highway System for Transit." Washington, DC: Transit Cooperative Research Program, Transportation Research Board. This report describes the intended and unintended consequences of the development of urban interstate highways for transit by examining four metropolitan areas in the U nited States, four selected cities in Germany, and one city in Canada. The report includes profiles of these communities, their transportation systems, and the positive and negative impact s of their transportation choices. The authors gathered infonnation from published articles, official plans, and interviews with officials and other knowledgeable people in each community. They also visited each site. Their goal was to understand the history of the development of the intersta t e h ighway system within the urbanized area and the int eractions between highspeed limited -access roads and changes in t he transit system and land-use patterns. The case Studies were selected to test two majo r hypotheses identified from the Jiteraturc review: that the interstate highway program biased transportation investments in favor of high-speed limited-access highways that made automobile travel much more attractive than transit use; and that interstate highways facilitated the suburbanization of households and firms, producing a pattern of development that is difficult for public transit to serve. Anoototions The authors present evidence from these case studies that confirms that the development of the interstate highway system adversely affected public transit. The data show declines in transit ridership, increasing difficulty in maintaining transit service l eve l s, and the decentralization and dispersion of households and jobs in case study regions with the highest use of interstate highways. Yet the authors correctly point o u t that transit was in decline well before the interstate system was operational, and other factors supported development in outlying areas, such as low property tax rates, inexpensive land, and the growth of competing local governments. The authors co u ch their main findings within other significant influences in th e decline of transit: I) The magnitude and certainty of publi c funding has influenced modal investment choices. These choices in tum, have affected regional travel. 2) Those cities whose citi zens have shown a continuous commitment to, and inves tment in, high-quality transit service have strong urban centers and high transit use. 3) Strong, well-respected institutions build and operate transit systems in the regions where the impacts of highways on transit are low. 4) Active, wellorganized citizen groups mitigated the impacts of highways by successfully opposing certain highway designs as well as highway construction itself. 5) Tbe integration of transportation and land-use policies, plans, and projects has mitigated the impacts of automobile infrastructure rRANSIT COOPERArrvE RESEARCH PROGRAM (rCRP/ HIO

The region's travel demand model, which was enhanced to increase its sensitivity to density and Rutgra lrooklng 8f'iM:brhoff ECONorthwt 150 Anrtototion1 design, is used to simulate the transportation outcomes in 20 I 0 of each of the alternatives. The study finds that the package o f transit oriented develop m ent and transportation improvements that focus on non-automotive modes generates the following effects within the study area: Reduces auto ownership rates by 5 percent from auto-oriented levels Reduces single-occupant auto use for work trips to 58 percent compared to 76 percent in auto-oriented alternatives More than doubles the share of work trips made by transit ove r auto oriented alternatives (18.2 percent versus 8 8 percent) Reduces daily vehicle trips per house hold from 7.5 to 7.2 trips Reduces the delay over "no build" level s by more vehicle hours than highway building alternative (53 percent reduction versus 43 percent reduction) Reduces peak period vehicle hours of travel at three times the rate that the "highway" building alternative doe. s (15.7 percent reduction versus 5.6 percent) Reduces daily vehicle miles of travel by 6.4 percent, whereas the "highway" building alternative increases them by 1.6 percent. One caveat, however, is imponant to note The study area encompasses the fastest growing part of the Ponland metropolitan area The impacts would like l y be less if transit-oriented land uses and transportation improvements were built throughout the metropolitan area, since the remainder of the region has less growth to focus toward transit oriented developments.

Using data from the 1980 and 1990 Censuses, Cervera compares the jobs housing balance of the 23 largest cities in the San Francisco Bay Area. His evidence shows that the jobs-housing balance generally improved during the decade, particularly as jobs increased in formerly housing-rich areas. However housing did not grow significantly in job-rich areas, largely because zoning and growth controls prevented housing growth Fifteen of the comm unities studied showed small increases in the ratio of internal conunuting to external commuting. Nonetheless, about twice as many people commuted in and out of the average community as conunuted within it. Thus, he concludes that despite less segregation of uses (measured at a gross city-wide scale), many people continue to commute considerable distances in part because of mismatches between the TRANSIT COOPERATIVE RESEARCH PROGRAM (TCRP) H -10

jobs available in their community and the type of housing found there Among other things, this descriptive study demonstrates that the transportation consequences of spatial segregation of uses need more careful consideration than just a look at the numbers of residences and jobs. The mismatches between the incomes of employees and hous ing prices and between new jobs and housing availa bility also must be considered. 4. 3 Neighborhoods Cervero, Robert, and R. Gorham. 1995. "Commuting in Transit Versus Automobile Neighborhoods.'' Journal of the American Planning Association 61 2: 210-225. This study compares work trip mode shares and trip generation rates between matched pairs of transit-oriented and auto-oriented neighborhoods. Sev en of the pairs are located in the San Francisco Bay Area, and six in the Los Angeles area. Transitoriented neigbborhoods are defined as those built around streetcars or rail stations prior to 1 945, which have a grid street pattern. Auto-oriented neighborhoods are those built after 1945, with little orientation to transit, and with more curving and cui de-sacs. The neighborhood pairs in the study had sim ilar incomes and as far as possible similar levels of transit service. Six of the seven San Francisco pairs showed the expected of lower auto ownership and more use of transit and walking for work trips (In one pair with a large university in the transit neighborhood, the transit neighborhood had less incidence of driving alone but walking often substituted for trans it.) The difference in the share of driveRutgeor ltooklng Ponoru trlnclt.,moH ECONorlt.weJI 1 S 2 Annolations alone rates between neigbborhood pairs ranged from 2.0 to 17.5 percent of trips. The results were more mixed in Los Angeles than in San Francisco, however. Tile authors conclude that neighborhood design matters little in the Los Angeles area because of the overw h e lming dom inance of the automobile in this region. Tbe results may also be muddled because transit service levels were less closely matched in the Los Angeles pairs than they were in the San Francisco pairs. Ewing, Reid, P. Haliyur, and G. W.

In this study, the authors compare six communities in Palm Beach County, Florida, on the basis of work accessibility, neighborhood shopping opportunities, and pedestrian accessibil ity They find little evidence that accessibility to retail affects mode choice or vehicle hours of travel per person. The shortest shopping and recreational trips occurred in a classic 1970s planned-unit development (i.e., a suburban auto-oriented community) because ample stores and recreational facilities could be found within the community. This result sugg est s that the mix of uses is as im p ortant as the layout of streets and other design features in determining travel behavior. TRANSIT COOPERAnVE RESEARCH PROGRAM (TCRP) H IO

Parsons BrinckerhotT Quade and Doug las. 1996c. "Influence of Land Use Mix and Neighborhood Design on Transit Demand." Unpublished report for TCRP H-1 Project Washington, DC : Transit Cooperative Research Program, Transportation Research Board. March. In this report, separate studies examine the effects of neighborhood land-use mix and urban design on the demand for transit and other alternatives to the automobile. The first study uses Annual Housing Survey data for 1985 for II large metropolitan areas to compare mode choices for work trips of residents in areas with and without easy access to a "comer store" or other commercial activities. A second study of the greater Chicago area uses transit and land-use data to identify the factors that influence individual transit trips. The third study compares the mode choices for work and non-work trips in "traditional" and "suburban" neighborhoods in the San Francisco Bay Area, using original survey data. All of the studies use multi linear regression techniques to control for income and other household characteristics. Overall, the studies show that the types and mix of land uses do influence the demand for transit, as well as the use of non-motorized modes. Peop le who live in mixed-used neighborhoods have a lower probability of commuting by car (3 to 4 perc entage points), a slightly higher probability of using transit (I to2 Annotolionl percentage points), and a much higher probability of walking or bicycling (10 to I5 percentage points) for work trips. In the Chicago area, a 10 percent increase in residential density is associated with an II percent increase in the number of trips by transit. Residents of "traditional" neighborhoods in San Francisco are more likely to use non automotive modes for non-work trips than residents o f "suburban" neighborhoods. The neighborhood comparison stu dy, however, did not find statistically significant differences in mode choice for work trips between the two types of neighborhoods Moreover. all these studies found it d ifficullto sort out the effects of land use mix and urban design, because these characteristics are so strongly correlated with density. When density i s included in an equation, mix and design variables generally explain little about mode choice. Each of the studies controlled for residential characteristics such as income and auto ownership. Because the studies are cross-sectional, however, they show only correlation between land-use characteristics and mode choice. not causality. 5.

They maintain that evaluating ttansportation performance in te rms of accessibility allows a more balanced approach to lransportation analysis and problem-solving. Increasing accessibility by bringing urban activities closer together through more compact development and the inter-mix of land uses, as well as by promoting tele-travel, can substitute for physical movements Although not a replacement for mobility -b ased planning, accessibility measures help gauge progress toward meeting other regional objectives like sustainability and social eq uality. The authors use census ttansportation planning data to study trends in job accessibility between 1980 and 1990 with the San Francisco Bay Area serving as a case contex t The objectives of the analysis are multifold: I ) The work seeks to advance the use of accessibility indicators as inputs to long range lransportation planning and monitoring; 2) The work a ims to enrich how job accessibility is measured by introducing an "occupational match" refmement; 3) The authors employ empirical measures of job accessibility to address the spatial mismatch question ; and 4) The work calls for more formally institutionalizing and expanding the use of accessibility indicators for evaluating and moni toring long-term lransportation system performance as well as progress toward achieving broader social welfare objectives. The research showed that the Bay Area's largely market-driven patterns of regional employment growth failed to improve job accessibility among residents of the region's poorest inner city neighborhoods. Minority neighborhoods in the inner East Bay and parts of downtown San Francisco AnnototloM averaged the worst occupational mismatches in terms of proximity to ava il able jobs throughout the 1980s Controlling for occupationally matched accessibility, educa tional l evels and vehicle availability, Bay Area neighborhoods with high shares of African Americans still had disproportionately high unemployment rates in 1990.

Cambridge, MA: Lincoln In st itute. October. This paper examines the growth of dispersed sulx:enters in the San Francisco Bay Area and the effects of this growth on commuting Cervera id entifies 22 employment centers with 7 or more workers per gross acre and 9,500 or more employees in 1990 Downtown San Francisco is the largest and most densely populated subcenter. Other centers are in Silicon Valley and the East Bay core area (Oakland, Berkeley and Eme ryville) ; 16 more are located further out in suburbs. Two of the sulx:enters did not exist in 1980 Employment in these sulx:enters grew on average by 23. 6 percent annually in the 1990s, increasing the regional share of employment in centers from 47.5 percent to 48.2 percent. The growth of these sulx:enters has produced an increase in vehicle miles of ttavel (VMT) for commuting trips. On average, one-way VMT increased from 7.1 to 8.7 miles during the 1 980s-a 23 percent i ncrease with the largest increases to be found in suburban centers. This increase in vehicle miles of !ravel is linked to both longer distances TRANSIT COOPERATIVE RESEARCH PROGRAM (TCRP) H-JO

and to greater use of single-occupant vehicles. Of these longer distances between home and work had more influence on VMT, since outside of downtown San Francisco and the eastern Bay Area, the vast m ajority of commuters used cars in both 1980 and 1990. Cervero estimates that more than four-fift hs of the growth in VMT is due to longer distances between home and work. Longer distances were especially important in increasing VMT in the more peripheral centers. While at least one of their previous studies suggested that job decentralization shortened commutes, this result has been explained mainly in tenns of recorded travel times, and typically measured at the aggregate, metropolitan-wide level. This study sought to refine the analysis of spatial implications on commuting by disaggregating data among employment centers, measuring highway and transit network distances, and examining commuting behavior during the 19801990 window of rapid suburban employment growth. When combining refined commute distance measures with data on shifts in modal distributions and occupancy levels, the finding is that employment decentralization is associated with substantial increases in commute VMT per employee. Cervero attributes these longer distances both to regional growth and to mismatches in the job and housing markets that necessitate long commutes. 6 THE COSTS OF TRAVEL Apogee Research, Inc. 1994.

The Costs of Ewing, Reid. 19!)7. "Is Los Angele.< Style Sprawl Desirable?" and Gordon, Peter and Harry W. Richardson. 19!na. "Are Compact Cities a D esirable Planning Goal?" Journal of the American Planning Associ41ion 63, 1 (winter): 107-126. These two articles published in the American Planning Association Joumal debate the sprawl issue. The first article by Reid Ewing paints sprawl as undesirable. It defines sprawl not as suburbanization per se but rather as a wasteful form of ourward development. Sprawl is characte.rized by: I ) leapfrog or scattered development; 2) commercial stri p development; or 3) large expanses of low density or single-use development. Ewing points out two indicators that typify sprawl---suburban environments that are difficult to access and those that lack functional open space. Locations tha t are difflcult to access are those far from the core and from each other; locations that lack functional open space arc defined as those where open space is totally private and cannot he used to link neighborhoods, buffer incompatible uses, o r provide space for social interaction recreation or civic functions According to Ewing, sprawl is reinforced by consumer preference, technological innovation, public transportation subsidies, and the "more than shelter" concept of the hou sing market. Costs of sprawl include increased: I) vehicle mile.s traveled; 2) energy consumed; 3) public/private infrastructure; 4) depletion of developable and fragile lands; and 5) psychic and social stress. The cures for sprawl include more government oversight in the form of state and regional planning and more compact, mixed-use cluster development. Annotations The second article by Peter Gordon and Harry W Richardson attempts to attack "compact cities" as an alternative to spread-ou t metropolitan development or sprawl. Gordon and Richardson define compact citie.s as those with high densities at a macro or metropolitan level; 2) even higher densities at a micro or neighborhood/comrnurtity l evel; or 3) even higher densit ies at a downtown or central city level. Gordon aod Richardson reject compact cities because: I) people like low. rather than high-density living; 2) there is no real chance that at either a national or global level there will be a shortage of land; 3) there is currently an energy glut, and therefore no need to alter residential preferences to conserve fuel ; 4) the automobile is the most efficient and preferred way to access residential neighborhoods, and ideally suited to spread development; 5) suburbs are not congested and by their location have contributed to less inner-city and inner suburb congestion; 6) inner city ( compact) and suburban (spread) work and shopping trips are compatible; 7) agglomeration economies, once the province of cities, have now moved to suburbs; and 8) central locations have no market and continue to decline, and their rescue is a wasteful misallocation of public funds. Given these reasons, no case can be made for compactness as a deseription of desired urban form. Which article is right? The answer is probably both. People appear to prefer the accroutrements of suburban living but dislik e strip commercial development; 2) they want to distance themselves from urban problems, but worty about energy and land consumption; 3) they like their automobiles but see merit in transit; 4) they see a growing sophistication in sub urbs but acknowledge a need for safe and functioning cities; and 5) they travel and function in an environment TRANSIT COOPERATIVE RESEARCH PROGRAM (TCRP} H-I 0

Journal of the American Planning Association 58, 1: 60-71. This paper estimates the subsidies of automobile use in Madison, Wisconsin, a mediu m-sized city, in 1983. Hanson uses data on highway costS and taxes in the city and detcnnines that direct subsidies for highway infrastructure. maintenance, and policing were equival en t to $0.024 per passenger-mile or $105 per person in 1983. I ndirect subsidies for air and water pollution, petroleum prices, land-use opportunity costs, and personal injury were estimated from national data, and are, therefore. les s precise than the highway data. Nonetheless, he calcu lat es that indirect subsidies were equal to $0.034 per passenger mile or $257 per person. In this estimation of costs, the largest subsidies were for personal injury (36 percent), highways (23 percent), and air pollution (15 percent) Hanson contends that subsidization of the automobile produces more dispersed patterns of deve lop ment than would occur otherwise. Furthermore, he claims tha t sprawled developmem limits transportation options by making the automobile the only viable source of travel. Litman, Todd. 1995.

Litman estimates tha t for urban travel during peak periods, a mile of travel by automobile cost s $1.33 Of this amount, $0.16 is anriblltable to variable vehicle costs, $0.25 to fixed vehicle costs, $0.31to user time and risk, and $0.61 to external or societal costs su ch as pollution and land use impacts.

Litman does not separate out govern mental costs of trdvel. Those costS paid by users. such as roads bu ilt with gaso line taxes, are considered user costs; those paid through general taXes, such as policing, are l umped in external costS. The largest external costs in Litman's scheme are for air pollution, accident cos t s not paid by the user, the opportu nity costs of land currently used for roads, and external costs of energy consump t ion such as tax subsidies energy security, and environmental damage. Litman contends that land-use costs are a legitimate cost of automobile use because auto use encourages sprawl. It requires large amounts efland for transportation facilities and makes development of the urban fringe much easier.

lhe of Sprowl-Revisited higher transJl()rtation costs. Indeed, Litman estimates that land-us e effects cost about 7 cents per mile, compared to 33 to 35 cents per mile for owning and operating the vehicle and 17 to 23 cents for travel time. This study provides relative measures of the various costs of using the automobile versus other modes of travel; the calculations are based on estimates made by others. The data used rarely cover the full range of modes for which the author estimates costs. Thus, the figures in his tables are oft e n simplified. The author attempts to moneti:re all costs despite the lack of hard data on many costs The numbers are average estimates and do not consider location spec ific fact ors such as differences in costs for urban and rura l road building or congestion. The types of outcomes that the author counts as land -u se impacts of transJX>rtation are generally counted elsewhere in an analysis o f the costs of the sprawl and should not be counted again.

Conservation Design for Subdivisio11s: A Practical Guide to Creating Open Space Networks. Washington, DC: Island Press. Arendt published this book in response to numerous inqu iries concerning two earlier books on rural design principles. Readers wanted to know more about the techniques available to landowners, developers, local officials and conservation organizations who w e re interested in conserving land in the development process They were all looking for ways that land could be assembled and positioned so that communities could enjoy open space for years 10 come In this book, Arendt sets out principles that are far from novel, but them in a way that is easily understood by lay people. He addresses residential development around a central organizing principle-land conservation. He describes a way that ope n space can be R.utgrs Brookingt PorSQM lrindtertlolf ECONortnwe11 142 Anno.totion.s arranged so that it will create an int e r connected network of protected lands. Arendt views the "conservation subdivision" as the key component of this conununity -wide system of open space. Arendt's vision is for land-use planners to work much more closely with conservation professionals, and with developers and landscape architects, to help strengthen the "Greenspace Alliance." The author believes that this can be accomplished in a way that respects both tlte rights of landowners and the equity of developers. According to his view, developers can build at full density only when their desig n includes meadows. fields and woodlands that would otherwise have been graded, and convert e d into house lots and overly wide streets Beaumont, Constance. 1996b.

Michigan SOOety of Planning Officials (MSPO). 1995. Patterns on the Land: Our Choices, Our Future. Rochester, Ml: Michigan Society of Planning Officials. This report by the Michigan Society of Planning Officials (MSPO) reveals that, over the past three decades, Michigan has experienced a major population shift to suburban and rural areas Spraw l is most apparent in Southeast Michigan, the Grand Rapids area, and Traverse City, but is also occurring in most of the lower half of the l ower peninsula, and in a number of northern counties. The study's authors claim that there is a growing sense of community degeneration, manifested by citizens at public bearings on land use. The authors warn that if this pattern of development continues. certain costs and problems will be created, including significant public capital and maintenance expenditures channeled to water. sewer. roads, and other infrastructure; the continued decline of urban areas; the loss of jobs in key resource-based industries such as agriculture, timber harvesting. and mining once open land is convened to residential and commercial uses; the loss of the aesthetic appeal of n atural open spaces ; and the l oss of a distinct edge between city and country in the developing landscape.

Cluznging Pliues: Rebuilding Communities in the Age of Sprawl. New York: Henry Holt. The authors begin with the premise that many of America's communities (new as well as old; suburban and rural as well as inner city) are not functioning as they should. There are a number of reasons for this. but Moe and Wilke stress the fact that the leaders and residents of these communities have either made bad choices, allowed bad choices to be made for them. or made no choices at all. They claim tha t communities can be "shared by choice" or they can be "shared by chance." In other words, we can continue to accept the communities we get, or we can insist on getting the kind of communities we want. Moe and Wilke assert that the design of most contemporary American communities is largely determined by highway engineers and superstore developers They have stepped into the void left by public officials (who are either resigned to, or eager for, this kind of development) and by citizens-who are either complacent or powerless. Communities are built in a series of steps, each one so apparently logical or innocuous that it goes unchallenged. The result, as the authors point out is rampant sprawl. a phenomenon that has reduced the social and economic vitality of traditional communities and filled millions of acres of fannland and open space with "formless. soulless, unconnected structures." Moe and Wilke put forth two alternatives to sprawl: (1) better planning of how we use our land; and (2) the use (or reuse) of the capacity of older neighborhoods, towns, and downtowns to a greater extent than they are used currently Both alternatives, TRANSIT COOPERATIVE RESEARCH PROGRAM (TCRP} H-10

"Preserving Prime Farmland in the Face of Urbani:z.at.ion: Lessons from Oregon" Journal of the American Plilnning Association 58: 471-488. This article first reviews Oregon's effective combination of policies to preserve prime farmland despite intense urbanization pressures. It then proceeds to propose a scheme for comprehensive farmland preservation, building on Oregon's successes and mistakes. Prime farmland near urban areas is required for three imponant reasons: the production of truck and specialty crops; the provision of key environmental functions such as flood water absorption, air cleansing, and water filtration; and for open space protection and the provision of spatial definition to urban areas. Communities in every state have implemented farmland preservation techniques, with varying degrees of success. According to the author. for a policy to be successful it must influence the land market in the several different ways. It must increase the productive value of farmland; it must stabilize, reduce. or eliminate the value of the farmland tract as a single-family homesite (the consumptive value); it must remove the speculative value of farmland; and it must eliminate the impermanence syndrome. According to Nelson, property tax relief programs reduce the propeny tax farmers pay for urban and educational services which mostly benefit urban residents. As a result, this policy Rut9u 8rooking.t Por.on_. Brind;erfloff ECON:ortfwe ., 1 65 subsidizes housing costs and tums farmers into speculators. Rig1Jt-to1ann laws protect farmers from nuisance complaints from urban residents. However, although farmers usually win their legal battles, they often lose because of the heavy financial expense of the process. Transfer of deve/.opment rights (TDR) and purchase of development riglrts ( PDR) programs preserve farmland by compensating farm owners for maintaining their farmland However, these programs often fail because the programs are randomly applied and usually result in isolated farmland tracts being surrounded by urban development. A final common strategy. agricultural zoning, restricts land uses to farming and other open space activities. Non exclusionary agricultural zoning also restricts lot sizes to certain minimums. Smaller minimum lot sizes (higher densities) usually result in a form of development called rural sprawl. As a result, nonexclusive agricultural zoning is generally only e ff ective when large lot size requirements ( 160 acre minimum) are coupled with strict development review. Exclusive agricultural zones, on the other hand, restrict all non-farm activities and require that farmland be used for commercial activities. This stra tegy can only be effective when all prime farmland is zoned for excl usive agricultural use and urban development pressures are divened to other areas Oregon has implemented a statewide program to preserve farmland in the Willame!te Valley. This 4.000 square mile valley, contains one-!lurd of the state's prime farmland; 40 percent of the state's agricultural products; and houses more than two thirds of the state's population.

Oregon's fannland preservation plan does not rely on a single strategy. Rather, it employs a multifaceted approach consisting of exclusive agricultural districts, urban growth boundaries, development restrictions in exurban areas, farm use tax deferrals and right-to-farm provisions Data from the 1987 Census of Agriculture suggest that Oregon s policies are working. They are preserving a viable agricultural economy, while at the same time accommodating a craze for hobby farms. The effectiveness of Oregon's effons can be further analyzed by comparing developments in Oregon with those in nearby Washington a state without a statewide farmland preservation plan. Oregon has lost more small farms than Washington, but it has gained more larger farms (over 500 acres), more commercial farms (over $10,000 in earn ings}. and more total farm acreage. According to the author, a successful farmland preservation plan relies on multiple tec h n iques and strategies which work together and reinforce each other. Z. LAND PRESERVATION AND SPRAWL: EMPIRICAL STUDIES Burchell., Robert W., and David Ustokin. 199Sa lAnd, Infrastructure Housing Costs, and Fiscal Impacts Associawd wilh Growth: The Literature on the Impacts of Sprawl venus Managed Growth. Paper prepared for "Alternatives to Sprawl" Conference, Brookings Institution, Washington, DC. March. This short summary paper reviews the major studies on sprawl through 1995. It draws heavily upon the research done by the same authors for the State of New Jersey, as well as the work of Annotation' James Duncan and Jam es Frank in Florida. This paper however, was prepared before Burchell's studies of Lexington (Kentucky}, the Delaware Estuary, Michigan, and South Carolina were released The paper examines the implications of planned development versus more traditional decentralized development in the areas of land consumption infrastructure costs, housing costs, and fiscal impacts. Most of the studies reviewed in the paper contrast sprawl with at least one other development pattern. Sprawl is described as development that typically i ncludes subdivision sty l e residential development and strip nonresidential development consisting of skipped over, noncontiguous land development, including low-density residential and low floor-area ratio nonresidential developments. In contrast, planned development is described as seeking to contain new growth around existing centers and limiting development in rural and sensitive environmental areas, usually accomplished by increasing the share and density of development close in to existing development The growth analyzed in this paper is assumed to consist of househo l d growth that in tum leads to job growth, which requires additional land. Ideally, this growth and the provision of facilities to accommodate it are handled in a timely, harmo nious manner. Traditional growth is shown to depart from the most harmonious possible path by locating residential and other development in "a new outer ring of the metropolitan area with access from this new outer ring oriented increasing l y to a beltway or interstate [highway] rather than central core job locations." Increasing under-utilization of core land and infrastructures result. This process is associated with the development of TRANSIT COOPERATIVE RESEARCH PROGRAM (fCRP) H-10

Traditional growth is costly because new infrastructure must be provided for those households and bus inesses located far out, and the old infrastructure must be maintained for those left behind Yet in the shol'l run traditional growth is not bad for a region. It distributes firms and house holds to localities that min. imize individual out-of-pock e t cos ts. No consideration is given to the larger societal costs or impacts of these individual choices. The alternative development pattern of planned growth channels the growth to more efficient location s over the long run. Most of the farout growth which arises in traditional development is contained closer to existing infras tructure and built -up areas. Thus. "in the final equation ... there is a more orde rly and Jess wasteful relationship between old and new development" (5). Another goal of planned development is the conservation of open space (i.e ., agricultural land. forests, and environ mentally sensitive areas). The New Jersey analysis compare s the impacts of development in New J ersey for the Rutg.e11 trlncUrfloR ECONoriflwe.tl: 167 period 1990 to 20 I 0 under two development scenarios-TREND versus PLAN. The authors developed a series of models to examine the relative effects of eac h sce nario. They found tha t more than enough land existed statewide to accommodate the projected twenty year development (I 990-20 10) of persons households, and employees under both traditional (TREND) and managed (PLAN) growth. The authors estimated that development under TREND would consume 292,100 acres, whereas PLAN could accommodate the same l eve l of growth but would consume only I 17,600 acres -175,000 fewer acres than the alternative (Burcbcll eta!. I 992b ). PLAN's overall land drawdown was 60 percent less than TREND. Managed growth would also offer the environmental ad\antage of preserving greater levels of frail and agricultural lands. If historical rates of loss are projected into the future, under TREND 36,500 acres of f rail lands would be co n sumed for dev e lopment during the 20-year period. By contrast under PLAN. frail and agricultural consumption drops to 7,150 acres, only 20 percent of the TREND scenario In other words, managed growth in New Jersey could accommodate future development and at the same time, save more than 30,000 acres of frail environmenta l lands. In a similar vein, although development under TREND would co nsume 108,000 agricultural acres between 1990 and 20 I 0. under PLAN, only 66,000 agricultural acres would be drawn down, representing a savings of 42,000 acres or 4 0 percent of prime agricultural land T!IANSIT COOPERATIVE RESEARCH PROGRAM (TCRP) H-10

The scoring method implicitly weighs the specific measures and describes the relationship between the measure and quality of life. The ranks in each category are then summed for an overall score that is used to rank the metropolitan areas. Each category has equal weight in the overall ranking, however, the authors discuss how the reader can use his or her personal preferences to weight the categories to get a personalized ove.raJI ranking of metropolitan areas. Although this book puts fonh a commo n sense and anecdotal notion of quality of life, it provides no theoretical underpinning or review of relevant literature. The authors' scoring system implicitly weights the various measures with no apparent basis other than their own opinion. Although the book acknowledges that individual s will have different preferences, the method the authors s uggest readers use to apply weights ranking categories will not yield a ranking based on preference because it does not change the weighting of the speci fie measures that went into the ranks by category. nor will it address measures that were not considered.

Many states, cities, and hamlets use indicators to measure their own economic and social health, and to set furure goals. This article takes a look at these indicators which are often referred to as "benchmarks" or "vital s igns." Local governments often create these measures, but they are sometimes developed by community groups All indicator projects discussed in this at1icle used some public proce ss to identify specific measures. Cenain indicator projects have a specific focus, such as government performance or the environment; others are more comprehensive. Three examples are lis ted below. Jacksonville, Florida developed a Quality of Life index in 1985 and updates the index annually. A 1991 community review of the index revealed education as the community's top priority. The other categories in the index include the economy, public safety, natural environment, health, social environment, government and politics culture and recreation, and mobility Specific measures used in the index include the number of outdoor sign permits issued, the cost of 1,000 kwh of electricity, student fitness t est scores in 50th percentile or better, and repons of commute times of less than 25 minutes. Jacksonville has recently developed an equity index that provides a neighborhood level looks at measures from the Quality of Life index related to delivery of public services, such as police response times.

Urban sprawl i s d efi ned by the author as very low-density urban development, oriented to the automobile, with detached single -family houses on rela t ively large lots. For Popenoe, urban sprawl implies a scatteration of jobs, shops. and services, often in the form of strip commercial development; a scarcity of large open or green spaces; and a lack of community focus in both the physical and social sense. Despite itS negative image however, he points out that most Americans live in environments characterized by urban spraw 1. Many Americans, including some sociologists, se e urban sprawl as Annotation' desirable when compared to crowded, noisy, violent, and corrupt cities.

Urban sprawl, however, has been attacked as expensive and a s ignificant user of nat ural resources. especially land and gaso line This article examines the effects on residents of living in low-density, suburban residential e nvironm e nts. Since the positive consequences of suburban living are reasonably well known this article is devoted ins tead to the negative conseque .nces. Four negative consequences have been fairly well-documented by sociologists: I Low density suburban development bas led to an intensification of resi dential segregation by race and social class. 2 The benefits of urban sprawl are distributed regressively with respect to wealth. 3. Of all the alternative forms of urban expansion urban sprawl is the one that is most destructive to the center city. 4. Although not an inherent conse quence of low-density development, urban sprawl, when linked up with America's small scale, semi autonomous local governments, has led to the proliferation of fragmented and overlapping governmental units. The negative consequences of urban sprawl appear most tangible when considering the situations of five groups: women, teenagers the poor, the elderly, and the handicapped. The author states that "it is hard to escape the conclusion that urban sprawl is an urban development form designed by and for men especially middledass men." Urban sprawl functions best when a resident has regular and direct access to an automobile, and middleclass men TRANSIT COOPERATIVE RESEARCH PROGRAM /TCRP} H-10

The Costs ol have more access to an automobile than the peop le in the five groups listed above. Fu rthermore, a major negative consequence of urban sprawl is deprivation of access. Even where community facilities and services are present and people can afford to use them, a large percentage of the population is disenfranchised from their use, due to in adequate transportation. A closely related negative consequence is environmental deprivation from a deficiency of local clements that provide activity, stimulation, and well being. This consequence applies particularly to teenagers. The walking environment of the l ow -density American suburb is virtually the sole environment for the teenage resident Yet in this env ironment homes are often placed so far apart that access to local friends is difficult. Moreover there is little diversity or variety of activities. The be.st amenity that usually is offered is a shopping cent er, or perhaps a fastfood restaurant, where teenagers are often made to feel unwelcome if they just hang out. Popenoe mentions other poten tial negative consequences, including "sensory underload" and the "fall of public man." He also points out tha t the suburban trend of d i fferentiation of residential areas by stages in the life cycle-with families. single adults, and the elderly inhabiting entirely separate neighborhoods breaks up the "round of life" and may have negative consequences for young people.

He attacks strip commercial development in suburbs and advances many of the ideas of the "new urbanism." He favors compact development over continued sprawL He suppons strong tree preservation ordinances and other environmentally sensitive regulations. Barnett traces the historic deve lopmen t of older core areas and shows why the desire of the rich to live away from the poor, combined with transportation improvements, caused a withdrawal of resources from the center of our metropolitan areas. Annotation Anracting new investment to the bypassed areas of the older city is also the other side of the coin of policies to restrict growth at the urban fringe. One will not work without the other (118) He argues that some urban ccnu-al business districts (CBDs) have been growing, but the remaining portions of older cities have been shrinking. The current market for a new suburb in derelict parts of an old city is likely to consist of people from nearby areas who have s tarted to make a little money, plus people whose other housing choice is a small house or a mobile-home way out on the urban fringe (146) The minimum require ments (of successful inner-city revival I are to foster a community [with I affordable housing, public safety, and effective schoo l s. ( 163) The future of older cities depends ultimately on public po li cy initiatives that canno t be controlled directly. Older centers and neighborhoods need rapid transit links to the new centers in fonnerly suburban areas so that the metropolitan area can function as one economy. MetropoHtan services have to be supported by an equalized tax base; there needs to be limits to growth at the metropolitan fringe accompanied by major new investment in bypassed residential neighborhoods and derelict industrial districts. R ein tegra ting the metropolitan area is necessary for the survival of cities, suburbs, and the regional eco-system (175) The book's weakness is that Barnett does not indicate how to implement !tis recommendations or h ow to grapple with the political forces invo lved.

But, he says: [L]ocal governments are not accustomed to making affirmative decisions about which areas of the n atural landscape ought to be preserved and which areas should be built up ( 191) The basic components of any city design are the organization of public open space inc luding streets, plazas and parks or gardens-the architectural relationships among buildings, and the composition of building mass in relation to the landscape or the skyline.

Renovating public housing Helping some low-income house holds move out of areas of concentrated poverty. Spending more on inner-city schools, rather than industrial subsidies. The environmental movement could be a strong political c onstituen c y for the maintenance and restoration of the old city.

In this shon essay, Drucker explains how the growth of cities in the nineteenth century was due to advances in transponation that enabled people to move to centralized locations to work together. But now the author points out, it is cheaper and more convenient to move infonnation to where the people are. Nevertheless, big corporations will still want their top people together; and many people will still want to work in TRANSIT COOPERA TJVE RESEARCH PROGRAM (TCRP) H l 0

groups. in the future, these groups will no longer n eed to be gathered in downtown office clusters. Work will be out-sourced to specialized finns that are not necessarily located downtown. We are probably at the end of the big boom in office consu:uction in major city downtowns, Drucker concludes. This essay covers no more than a fragment of the overall subject, without much depth of analysis and with very little supporting data. Fishman Robert. 1987. Bourgeois Utopias: The Rise and Fall of Suburbia. New York: Basic Books. T h is book discusses the role of suburbs in the historic development of modem urban life. It look s at the two phases of suburbia-the "original" suburb, and the post-industrial "te chnoburb .'' The original suburb, as defined by Fishman, was a retreat from the tumult of industry and commerce and high density residences that characterized the early industrial city into an exclusively residential community. It ftrSt appeared in the London area in the late eighteenth century, and became more prominent in the n.inctcenth and twentieth centuries, both in England and in America. The original suburbs were almos t exclusively residential areas, occupied almost entirely by the middle-<:lass elite; they excluded all industry and commerce, and all lower-income households. They were a retreat from the ills of city life into a more utopian scene linked to nature through the prevalence of single-family homes with private yards. Suburban life was family oriented and separated middle-class women from the world of work; it placed them in a world exclusively focused on the family. Annotation$ In F ishman s view, the suburb was a specialized bedroom community, the emplo yed residents of which commuted into either the central city downtown or its industrial areas; the employed residents never worked in suburbs themselves. Exclusion was at the heart of the suburbs as thus conceived. Industry commerce, diversity, jobs for women, and low-income households were all percieved as potential threats to the primacy of the family-<:entered, lot linked single-family home. Over time, however, the suburbs have gradually evolved into a completely different urban arrangement, su:uctured around what Fishman calls the "technoburb.'' I t can also be called the urban network form. What most people conceive of as the suburbanizat ion of America. Fishman considers a shift to a development pattern that radically undermines the original suburbs-and the old central city Although suburbs maintained their spec ialized roles as bedroom communities into the 1950s, the migration of so many other types of activities into suburban areas s ince then has changed the basic nature of these c ommunities. As they acquired first shopping facilities, then warehouses then industrial finns, and finally offices, they lost their exclusively residential character. They have been transformed into fully urban communities, but with no single center and with very low densities. This transformation was made possible by innovations in automobiles, roadways, and communications. Today, the metropolitan area is a non centered amorphous growth, resembling an amoeba without a nucleus. Although regional downtowns still exist, and central cities still specialize in housing the poor and some central faci lities and amenities, the vast majority of both residences and workplaces are scattered throughout the area in no particular TRANSIT COOPERADVE RESEARCH PROGRAM (TCRP) H-10

pauem. They are linked by a huge network of roads and electronic communications. The center of each person's life i s his or her own home, and the universe of each consists of the territory he or she can reach within one hour's drive from home. T h ere is no singl e centxalized urban fonn because each household essentially has its ow n un. ique network. The overall fonn is an undefined massive overlapping of aU these individual networks The e x clusiviry of the old suburb has been destroyed, although poor people still seem conc entrated in older core areas. But all types of activitie s are now found at all distances from any one spot; there i s no singl e center that everyone relates to. This uncentered network has replaced the m onocentric city of old, and even the polycentric city of the 1960s and 1970s. What most people pcrcei ve of as suburbanization today involves the destruction of the fonner suburbs and their full urbanization in a totally dece ntr alized form. A key question concerning t he future of this trend is: "Is the low density of the new city destructive to all cultural diversity?" ( 200 ) Since this new netwo r k. con tains very few public spaces and no set of place s in which a large ftaction of the community habitually gathers or interactS phys ica ll y, there is no sense of community Tc.Jevision greatly aggravates this outcome because it fosters passive home-centered separation of each household from all oth ers, alt hou g h it does provide som e commonality of experience across the multitudes (which may be undennined by the multiplicatio n of channels). Fishman believes we arc still working out the cultural impli cations o f this new form: The new city will probably never be able to compete culturally with the old centers There will be for the l\ltgen lrooiOno P'ottolu lrlr!cbthofl ECONortflw ll 1 8 I AAnototion' foreseeable future a division founded on choice between those who see k out even at great cost tbe ldnd of cultural excitement that can only be found in the center, and those w h o choose the family-centered life of the outer city. (202) Fishman, however, underestimates the degree to which culrural activities can take place in the outer regions of such networks, because people with common cultural i nterests can still gather together in outlying locations in sufficient numbers to support c u ltural activities like sympho nies theater s, etc. Seen i n historical perspective, suburbia now appears as the point of tran sition between two decentralized e ras: the preindustrial rural area and the postindustrial information societ y ... Suburbia kept alive the ideal of a ba.lance between man and nature in a society that seemed dedicated to destroying it. That is its legacy. (206-207) G l aese r Edwa r d L. 1 994. "Cities, l n format ioo., and Economic Growth." CltlscDpe 1 I ( A u gust ): 9-47. This article explores recent contributions to the theory of cities concerning how infonnation flow and usage contribute to city growth or decline. Glaeser argues that simple ca pital and labor accumu lati o n models fail to exp lain ciry growth. A variable relating to human capital and one relating to abstract inteUectual capi tal should be included in any analysis to explain certain failings in simpler models. One aspect of cities that is not often discussed is that of informational externalities. These help exp l ain why people and firms locate in cities and why ci ties grow.

negative impacts, they allow rioting to spread rapidly, and increases in crime to be communicated quickly. Growth theory regards increases in the s tock of human knowledge as a central aspect of economic progress over time. Because knowledge is more easily accessed by people living close together, "closeness contributes to the degree of appropfiability ." (II) Growth theory based upon capital and labor accumulation had an inconsistency: it could not explain why countries and cities did not converge on a steady state. Only an exogenous technological change variable could explain that. But increasing returns to scale from intellectual knowledge also made it possible to explain ccntinuous growth. However, increasing returns tO s cale are not compatible with an economy based upon perfect competition, hecause the fermer leads w monopolistic result s Also, marginal prices lie under average prices which means firms would be losing money Romer solved this problem by indicating that private profits did not have i ncreasing returns to scale, but social benefits produced by general increases in knowledge did. His argument made perfect compet i tion among private firms possible in theory, but also allowed growth to continue over time due to the social benefit s of accumulated knowledge. Lucas focused this i dea on returns to human (pri, ate) capital, but the truth must be that both private capital and general social knowledge gain from innovations in the long run. These ideas are related to cities because people living and working close together can more easily tap into the store of accumulated knowledge and exchange ideas with each other. The externalities of knowledge exchange are clearly &rooking Pot1ot11 8-rinck.rhoH ECONonhweJI 18 2 Annotation$ facilitated by urban proximity, as opposed to its alternatives Barro regressed growth in per capita GDP against several other variables across countries, and discovered that poor governmental qualities are negatively correlated with rapid growth. His basic findings were that education and absence of regulation were positively correlated with rapid growth. Rauch found that SMSA cities with high levels of human cap ital had both higher property costs and higher wages than other cities, holding individual traits constant. Glaeser and others arrived at the following findings: (I) initial concen tration in an industry does NOT seem to foster subsequent creativity, therefore scale economies in a local industry do not really create growth; (2) urban diversity is positively related to later growth; and (3) more competitive industries grow more quickly. In general equilibrium theory, real differences in incomes among cities should be quickly eliminated by migration of workers and capital. Any remaining differences should reflect negative amenities in the higher-income cities that must be offset by higher mcomes. A strong finding from U.S. census data is that the cities that grew quickly between 1950 and 1970 also grew quickly between 1970 and 1990. Growth in the first period was established as the best single predictor of city growth in the second pefiod. Thus, growth begets further growth in spite of congestion problems. At least, that is one interpretation of the data. Another finding is that areas with highly educated work forces at the outset of a TRANSIT COOPERACIVE RESEARCH PROGRAM (TCRP/ JI.JO

High-and low-unemployment rates among cities also tend to persist over time No convergence occurs. such as what might be predicted by general equilibrium theory This lack of convergence may reflect permanent maladies in the structure of those cities with high unemployment rates. Similarly, high crime rates are persistent over time among cities. Rioting is a phenomenon found mainly in cities, because of contagion and other effects. Almost every city has a potential for rioting if some s park ignites a crowd Neighborhoods play key roles in the accumulation of human capital. Both skills and behavioral habits are learned from peers and neighbors and mentors. Stability of occupancy in neighborhoods may be important, because, a ccord ing to game theory the length of relationships influences the types of behavior one is willing to carry out. If you have a long term relationship with other players (neighbors). for example, you arc more likely to take the impacts of your actions upon them into account because they can retaliate against you in the future, and you must live with them for a long t ime Thus, residents in stable neighbor hoods can more strongly reinforce good behavior than residents in unstable areas-a finding that presents an argument for subsidizing homeownersb.ip, which creates greater residential stability. Cities also foster proximity to political power, which is concentrated there This proximity roay influence people to undertake actions to change the behavior Annotation a of key authorities located in cities. Political agitation is much more likely to work in cities than in rural areas for that reason. There are also more people to get agitated per unit of effort in cities than in rural areas. One of the most critical challenges in the future is reducing i n forma tional barriers between gheuos and downtown power centers. Suburbanization provides many of the of urban agglomeration while avoiding many of its negative impacts. such as high ra t es of crime greater probab i lity of rioting and less residential stability in local neighborhoods to inhibit negative behaviors.

These anti-urban trends are further reinforced by "push" factors lilce crime, panhandlers, and "dysfunctional public agencies" that are found in downtown locations. People continue to leave the se ills for better amenities and more pleasant shopping opportunities in America's suburbs. It is the authors' contention that these push -a nd-pull forces explain more than just the continuing demise of downtowns; they also explain the outward expansion of cities into suburbs and exurbs. Although the current political debate is about the contest between cities and suburbs, it is becoming less relevant. The more important question hinges on how much future development will occur in suburbs, exurbs, and rural areas. Gordon and Richardson point out that most U.S. job growth since the lat e 1980s has occurred outside of large Metropolitan Statistical Areas (MSAs}. This silent migration, the authors conclude, has had little impact on public policy because it does not match the conventional, but hopelessly outdated, paradigm of how cities evolve.

Annolohons The authors observe a steady decentralization, often beyond the suburbs into both exurban and rural areas. They see new and mobile ftnns choosing locations according to their demand for agglomeration benefits. These are now available throughout suburban and parts of ex urban America, obviating the advantages of traditional centers and of central counties as a whole. Exurban and rural settings are increasing l y attractive to firms becaus e of breakthroughs in goods handling and in the transmission of information. The authors' work shows a negative and sometimes absolute decline in CBD employment over the period of st udy The study suggests that the locational decisions of households are influenced more by workplace accessibility than by the availability of amenities, recreational opportunities, and public safety. In addition, the locations of firms are less tied to place because of access to infonnation teclmologies, just as core diseconomies have displaced the original agglomeration economies tbat pulled people and economic activities together. The authors therefore conclude that central cities are not corning back any time soon. Nelson, Arthur C., and Thomas W. Sanchez. 1997.

'ffie Costs of SprowJ-Revi$.ited Nelson and Sanchez use a variety of and cluster analysis techniques, and find that exurbanites and suburbanites are more similar than previously thought. They conclude that the rise of polycentric urban areas seems to have pushed the suburban fringe further out. The results of this analysis suggest that the primary differences between exurbanites and suburbanites is that the former have a greater desire to locate from urban-related problems and dsarnemlles. especially households with middle incomes and families with small children. In contrast, smaller families or families at the early or late stages of life are more likely to choose suburban locations. In conclusion, the authors speculate that the continued outward expansion may be attributable to the inabiliry of urban and suburban governments to provide suitable public facilities and services at prices affordable to residents, and to suburban policies that constrain the supply of housing relative to demand through opposition to affordable housing or innovative housing configurations, and through otherwise exclusionary zoning practices. Rusk Da,id. 1993. Cities Without Sub urbs. Washington, DC: Woodrow Wilson Center Press. This book is a detailed and compre hensive look at sprawl and at least one of its alternatives, written by the forme-r mayor of Albuquerque, New Mexico. Its basic thesis is that cities which have elastic boundaries-i.e., those that can annex surrounding territories-are much healthier than cities which have inelastic boundaries-i.e., those where boundaries are frozen because they are surrounded by incorporated suburban municipalities. The elastic cities can expand outward as their metropolitan Annolotion.s areas grow, enabling them to retain access to the new taxable bases created outside the original boundaries of these cities as they grew. In contrast, inelastic cities cannot reach out to new taxable resources as growth expands beyond their borders. Both elastic and inelastic cities have disproportionate shares of poor people within their original boundaries, but the former can counteract the negative effects by expanding their boundaries. Inelastic cities are stuck with rising percentages of poor residents and falling tax bases, causing them to have falling taxable resources per capita at the very time that they need more such resources to cope with the rising percenta<>es of poor residents. Rusk presents a great deal of statistical information to support his claim that elastic cities are healthier economically and socially than ones. He does not use regression analysis, but rather presents paired city comparisons and compares averages of groups of cities with different degrees of elasticity. This book is one of the most com prehensive and intelligent analyses of sprawl and other urban problems yet wntten. However, it has one serious flaw. The author believes that unified metropolitan government is the best solution for inelasticity, but there appears to be no political suppon for this arrangement whatever. Even so, Rusk's analysis is definitely one of the best studies of urban problems. Where Rusk particularly excels is in analysis of three aspects of the urban problem. First, he fearlessly confronts the racial aspects of urban problems. Second, he offers concrete recommendations for solving the problems that he describes. His recommendations include: regional governance of land-use planning; TRANSIT COOPERATIVE RESEARCH PROGRAM (TCRP) HlO

PAGE 194

regional tax-base sharing; a regional program of creating desegregated affordable housing for the poor; and promotion of region -wide economic development. Third, Rusk presents a cogent analysis of the "point of no return" for central cities. He identifies three benchmarks: a low ratio of per capita income in a city relative to that of its suburbs (70 percent or less); a high fraction of minority-groups (30 percent or more of the total population); and substantial and sustained population loss (20 percent or more). He claims that no city that has crossed all three of these thresholds has ever even begun to recover. Sclar, Elliot, and Walter Hook. 1993. "The Importance of Cities to the National Economy.'' In Henry G. Cisneros, ed., lnterw()vtn Destinies: Cities and the Nation New York: American Assembly of Columbia University. 1 -26 This is the lead anicle in a volume of essays presented at the 82nd American Assembly held in Harriman, New York in April 1993 The authors argue that central cities are the vital centers of production in the American economy. They complain that most policy analysts in recent decades have viewed cities mainly as homes for the poor. They cite the following facts in support of their view on central cities: In most metro areas, the higher paying jobs are located in the central city. Such jobs constitute 32.2 percent of all jobs nationally, bot garner 37.7 percent of nationw ide earnings (no sou rce for this data is cited). Wages of central city jobs are 20 percent higher on average than those of suburban jobs. and this gap has been widening. Many suburban residents have jobs in central cities. A survey by Arthur A.nnototion1 Goldberg of the suburban areas of the nation's 100 largest ci t ies showed that half of suburban families had at leas t one worker in the central city. The same survey showed heavy suburban dependence on central city services. Approximately 67 percent of suburban residents depend on the city for major medical care; 43 percent have family members attending or planning to attend an institution of higher learning in the city; 46 percent believe their property values would be hurt by a serious decline in their central city. The top 24 counties accounted for 39 percent of all jobs in information intensive industries but had only 27 percent of total jobs. Wages for jobs in downtown Boston were 3.55 times higher than wages for jobs in the same categories in the suburbs. and 2.37 times higher in New York City than in its sub urbs . The production advantages of central cities include: (I) minimized transportation and communications costs fo r both workers and customers; (2) easy face -toface contact among expens. which facilitates analysis; (3) superior telecommunications infrastructures which facilitates international tran sactions ; and (4) more specialized producer services. which tend to be located where the size of the market is greatest. One reason suburban locat ions continue to grow faster than central cities is that the costs of moving are not fully borne by the businesses that move. Some of the cost is borne by their employees and public taxpayers If suburbanization were so efficient, one would see more of it in international competitor nations. Instead, the growth of the suburbs in the United States indicates that U S. urban policy is more concerned with stimulating demands for consumer TRANSITCOOPEIIATIVE RESEARCH PROGRAM (TCRP) HlO

The nature of pricing of telephone and other services has allowed higher-cost suburban services to be priced at th e same rate as lower-cost city serv ic es. The authors argue that continued dispersal poses major costs to society, especially concerning the i nputs of private firms. The need for virtually all emp l oyees to own automobiles, for example increases wage demands. Auto dependence also increases our trade deficit because we must import so much oil. We already spend far more on travel and telecommunications than rival nations. The Japanese spend 9.4 percent of GNP on transportation, while we spend 15-22 percent. Traffic congestion imposes high costs on production. The authors claim tha t most metropolitan areas devote over half of their available land to road infrastructure. By undcnnining the tax base of central cities, society has been unable to invest properly in the education and training of the labor force, or in the infrastructure outside the downtown that is critical to productive efficiency U.S. investment in education through the high school level is the lowest among the seven most industrialized nations-4.1 percent of GNP, compared to 4.6 percent in West Germany and 4.7 percent in Japan. We need much more investment in the labor force and infrastructure in central cities to remain competitive. Rulfei's lrooking PorSOtls 8-rlndterflolf ECONotlflwe.t 187 2. URBAN DECLINE Andrews, Marcellus 1994. "On the Dynamics of Growth and Poverty in Cities." Citiscape 1, 1 (August): 53-73. This article presents a model of how povcny concentrations within cities are re l ated to city growth rates. "The central the me of this article holds that the logic of meritocracy creates class divisions in the urban labor market which may undennine the very conditions tha t make rapid economic growth possible" (53). The need fo r high-skilled workers in a modem high -t ech economy creates two classes of workers: those with the requisite skills, and other unskilled workers. But schools in many large cities are failing to provide their students with the skills needed to be in the first class. This failure creates a caste like result, since the primary determinant of the school performance of children is the educational level of their parents. The basic dynamic, Andrews points out, is as follows: Members of the "underclass'' within cities strive to attai n a higher standard of living and job s suitable for high skilled workers, but are frustrated by their inability to do so because of the poor quality of city schools. The lifestyles of the middle class have a demonstrable effect upon the underclass, encouraging them to want to consume more. The resulting frustration leads to criminal behavior and violence on the pan of the underclass. Members of t hi s class perceive that they have only two sources of income-transfer payments and c rime. The behavior of the underclass drives middle-class (upper-t i er) workers and households out of the city into the suburbs where they can escape from crime and violence.

The depanure of the middle class weakens the fiscal position of the city government, thereby reducing its ability to provide good quality schooling to the underclass. This c .reates a negative downward spiral a .. vicious circle." A key variable in this dynamic system is the "middle-class ratio"-that is, the percentage of the total population consisting of middle-class residents. Another key variable is the ani tude of students towards academic achievement. The author argues that membership in the underclass causes anti-academic attitudes among students Andrews also argues that th e re is a "critical failure ratio'' among city students which determines whether the m i dd le class w ill grow or decline within the city. If the actual failure rate among students (which determines whether they will become middle-class or under class members) rises above this critical rate, the middle-class ratio will decline because the behavior of the underclass then larger, will drive middle-class residents out. If the actual failure rate is below the critical level, then more students will graduate into the middle class. and the incent ives for middle class residents to leave is reduced-even t h ough greater competition in the labor market among the larger numbers of middle-class workers may cause the unemploym e nt rate to rise. The author regards this entire situation as a negative externality -an unintended consequence of technological change that has raised the skill requirements for high wage workers. But it is society that has provided unequal access to learning among its young people. Thus, "the increasing importance of knowledge capital in economic growth contributes to the problem of urban poverty." (63) Annotation:. The future of the city, and particularly its ability to change the way it grows, may ultimately depend upon the willingness of the middle class to remain in the city despite the difficulties of ca ste division and crime that are the underside of the role of knowledge capital in economic life. In tum a national government policy that encourages the exodus of middle-class citizen s from the city may make significant urban reform and struction impossible. (63) The federal government must recognize the role of knowledge capital in unwittingly exacerbating the urban crisis. In panicular any urban PQlicy that in tends to make cities into virtuous circles must recognize the folly of forcing local governments to deal with the negative aspects of knowledge capital with d iminishing economic resources. Furthe r a macroeconomic growth strategy that emphasizes human capital must carefully address the inequal.ity, poverty, violence, and crime that result from educational failure.

A central component of this b ook is the idea that every city has certain specific social functions, and therefore changes in its ability to perform those funct ions constitutes urban decline. In contrast, a low level of ability to perform those functions-a static concept-constitutes urban distress. The authors point out that not all cities with high urban distress are declining. Some may even be growing rapidly-cities with high poverty rates and high immigration, for example. TRANSIT COOPERATIVE RESEARCH PROGRAM {TCRPI H-10

Th e seores of each city on all four variables w ere then summed The highest possible index score was +4 and the lowe s t wa s 4 A sim ilar index was compu t ed for city urban distress. This index was based on five variables each at a single point in time: the unemployment rate, the incidence of poverty, the violent crime rate. the percem of housing considered old, and the city's tax revenue relat.ive to that of its metro politan area It is notable t hat neith er city p o pulation cha nge nor ci t y employment c hange was used as part of the decline measu re. The reason is that not all popu lation decli nes are bad (if the city is overcrowded to start). Moreover, the authors used declining population as a separate measure that they related t o the index of decline. They reasoned that the u n employ ment ra t e captured some aspec t of emplo ymen t c hang e. Two other measures w ere com puted in this s tudy: city disparity, a measure of the difference betw een each cenlral city's scores for these variables and the sco r e of its suburban areas; and city divergence, a measure of lbe rate of change in city disparity over time.

The Cosh: ol Sprowi-Re'lisited knows how strong or important they are because no studies have measured them. He devotes most of his article to agglomeration economies, which have been studied at length and by many people Agglomeration economies are, essentially, increasing returns to scale in processing activities. Ihlanfeldt refers to tbem as "tbe economies of large-scale production, commonly considered, (and) the cumulative advantages accruing from the growth of industry itself-the development of skill and know-how; the opportunit ies for easy communication of ideas and experience; tbe opportunity of ever-increasing differentiation of processes and of specialiUltion in human activities." (128, quoted from Nicholas Kaldor -1970) Agglomerat i on economies are divided into two types: localization economies tha t arise from the concentration of similar activities (such as a single industry ) either in one place or very near each other; and urbanization economies that arise from the location of an activity in an area that a wide diversity of activities-so production costs decline as the size of the area concerned rises. U rbanization economies genetate benefits for all types of firms located in an area; whereas localization economies generate benefits only for those firms in industries that are highly concentrated in an area. Central cities are considered to have advantages over their suburbs for both types of economies. Both types of agglomeration economies have three major causes : ( l) labor market economies; (2) scale economies in the production of intermediate inputs; and (3) communication economies. Labor market economies cause localiza tion economies because the concen tration of many similar ftrms together creates a large pool of workers skiUed in that industry, and reduces search and training costs for the firms. U rb ani zation economies also arise from large diversified labor pools. However. these labor pool economies do not favor central cities much over suburbs in large metropolitan areas. The other two causes of agglomeration economies, however, clearly favor central cities. Both types invo lve faceto face contacts, which occur most efficiently in or around downtown areas. The importance of communications economies bas also been increased by the shift from goods producing to information-producing activities. Innovation s in communications technology however, have made face-t o-face contacts less necessary for the sharing of information. The author reviews numerous empirical studies of these economies One of the more interesting shows that both suburban firms and central city finns rely beavily on central-city suppliers for certain corporate services such as investment banking, commercial banking, and legal, auditing and actuarial services. The study, authored by Stanbeck in 1991, dealt with 14 large metro areas, and also demonstrated that suburban companies tend to be smaller and more likely to be in manufacturing than central city companies. Several other studies have correlated conditions, such as levels of per capita income in cities and their suburbs. These studies all show positive linkages between cities and suburbs. Yoith (1994), for example, shows that positive city income growth is highly correlated with positive suburban income growth. The author's conclusions are: Significant linkages clearly exist.

and social terms. The social costs include the destruction of community and family life. In the last chapter, Kunstler puts forth policy suggestions including the following: We must rebuild our cities and towns. We shall have to give up mass automobile use. (248) We should adopt the approach of the new urbanism in designing small towns. (He specifically discusses Sea side and Peter Calthorpe's pedestrian pockets as cures for all the ills he has been blasting. Mandatory open space zoning is also praised.) Until we do these things, "the standard of Jiving in the United States is apt to decline sharply. and as it does the probability of political trouble will rise."

This is a statistical study of tbe rela tionship between income disparities in central cities and their suburbs on the one hand, and metropolitan area growth rates on the other.

Overall, central city per capita income as a percentage of suburban per capita income has declined from 105 percent in 1960 to 96 percent in 1973, to 89 percent in 1980, and to 59 percent in 1987. Much of this article aims at justifying a substantial federal aid package to cities, especially cities in distress.

This concentration also produces a host o f other negative conditions. Sprawl undermines the transition of the inner -city unskilled workforce to a high-tech workforce. Sprawl thereby weakens the international competitive positions of U.S. metropolitan areas. Sprawl reduces the efficiency of businesses and the productivity of agricultural land.

The Costs of Spn;twi-Revisited stress deviancy and immorality of behavior among many poor people, with the newer theory attributing the behavior to the spatial isolation of the poor and especially of the poor blacks from white culture. Christopher Jencks claims that centuries of racial subordination and prejudice have created an unwillingness among blacks to do certain types of work or to work in white cultural environments. Black alienation from certain types of jobs is rarely discussed in analyses of poverty. The racial discrimination theory says that black poverty in particular is caused primarily by continued racial discrimination and the resulting spatial segregation. Massey and Denton, advocates of this view, argue that housing discrimination isolates poor blacks in poverty-concentrated neighborhoods with other poor blacks as their only neighbors. But discrimination itself is not new: so how can it explain rising crime rates or family instability which are recent developments? Massey and Denton claim that white prejudice and discrimination cause spatial isolation, which in tum results in cultural deprivation. The structural transfomration theory claims that black unemployment results from a change in labor markets and industry that has shifted more jobs to the higher-skill category and moved industrial jobs out of big cities where racial minorities live. William Julius Wilson is a leading proponent of this view. But unemployment does not explain many of the other pathologies of inner city poverty areas. Wilson also claims the departure of middle-class blacks from poverty areas has removed good role models, and the resulting negative culture is the result of economic deprivation and lack of Annotobons jobs. But i s it not clear whether cultural traits of blacks, rather than discrimination by whites. causes whites not to hire black workers The-social breakdown theory claims that poverty itself does not cause a cultural shift to negative values. Many poor neighborhoods do not exhibit such traits-especially poor areas occupied by immigrants. There are a variety of cultures in poor neighborhoods, and only in those where family networks break down does the culture of poverty arise. What remedies to alleviate poverty might be used? Cultural deprivation theorists stress the personal respo n sibility of the poor themselves, and claim they need to change their behavior. Their remedies involve orphanages for children of misbehaving mothers; forcing all poor people to work-including mothers; forcing fathers to pay for support for chi ldren; and making all government benefits temporary. (It appears that these arguments were embodied in the recent welfare "refonn" bill ) A major problem with this approach is that it assumes job opportunities exist for the poor with wages high enough to support decent living standards. This is not the case; public jobs programs would be nccessaty if all poor people were forced to work. Also, making all mothers work would reduce supervision over children and might worsen tbe children's behavior. Cultural deprivat ion theorists do not study or seem to care about the internal dynamics of poor communities, and pay too little attention to what might result if their remedies are tried. Racial discrimination theorists want strong anti-discrimination measures, and a big effort to spatial l y integrate society racially. This would require immense movements of people, a scheme that is 7RANSIT COOPERATIVE RESEARCH PROGRAM (TCRP) H-10

poverty, but they may improve the quality of life in inner -city areas. 3. URBAN RENEWAL Callhorpe, Peter. G. 1993. The Next American Metropolis: Ecology, Community, and the American Dream. Princeton: Princeton University Press. This book, written by an atchitect and urban planner, looks at the spirit of American communities and the "new urbanism" approach to altering that spirit. He primarily discusses changes in urban design, and presents relatively little quantified analysis As the author says, "Social integration, economic efficiency, political equity, and environmental sustainability are the imperatives which order my thinking about the form of community" (II). He those themes to the elCcessive privatization and indivi dualism he believes have been embodied in the suburban development process in the post-1945 period. The scale of our environment is now set in proponion to large institulions and bureaucracies rather than community and neighborhood (II). The suburb was the ... physical expression of the privatization of life and specialization of place which marks our time (9). The alternative to spraw l is simple and timely: neighborhoods of housing, parks, and schools placed within walking distance of shops, civic serv i ces, jobs. and transit-a modem version of the traditional town (16) As is the case for most planners, Calchorpe dislikes tbe automobile and the scaling of the urban landscape to accommodate it. He wants to change the Annolation scale to allow walking to suburban transit and linkages among outlying areas and the downtown area by transit. Caltorpe wants to make both housing units and lots smaller, link neighborhoods by walking paths, and encourage accessory housing. He strongly supports regional growth management, channeling growth inward to in-fill sites and limiting outward elCtension. At the core of this alternative philosophically and practically is I he pedestrian .... P edestrians are the lost measure of a community, they set the sca le for both center and edg e of our neighborhoods .... Two complementary strategies are needed. A Iough regional plan which limits sprawl and channels development back to he city or around subu rban lransit s tations ; and a macching greenbelt strategy to pre serve open space at the edge of the region We cannot revitalize inner cities without changing the patterns of growth at the periphery of metropolitan regions; it is a simple matter of the finile distribution of resources (20) This calls for regional policies and gove rnance which can both e du cate and guide the complex interaction of economics, ecology, j urisdi ction, and social equity .... Adding transit oriented new towns and new growth areas can reinforce the city's role as the region s cultural and economic c enter ( 32) Three constituenciesenvironmentalists, enlightened developers, and inner city advocates can find common purpose in regional planning goals.

U.. of Areas and potential New Town sites should be the work of an agency which spans the numerous cities and counties within a metropolitan area. Lacking such entities, counties, air quality boards, and regional transportation agencies often take on the tasks without legal power to fully implement the results. Regional governments are needed if growth is to be managed and directed in a sustainable manner (51). Suburbs are built upon a fundamentally wrong spirit and orientation: The rise of the modern suburb is in pan a manife.station of a deep cultural and political shift away from public life .... Socially, the house fortress represents a self-fulfilling prophecy. The more isolated people become and the less they share with others unlik.e themselves, the more they do have to fear ... The private domain, whether in a car, a home, or a subdivision, sets the direction of the modem suburb ... In fact, one of the primary obstacles to innovations in community planning remains the impulse toward a more gated and private world (37). Calthorpe's design strategy is based upon three major principles: First . the regional structure of growth should be guided by the expansion of transit and a more compact urban form; second, ... our ubiquitous single use zoning should be replaced with standards for mixedusc, walkable neighborhoods; and third, .. our urban design policies should create an architecture oriented toward the public domain and human dimension rather than the private domain and auto scale (41). He advances the concept of the TOD, or Transit Oriented Development-a basic Rlllgers Brooking Ponon Br!nckethoH ECONOtth.,.,..tt 197 Annolot\on$ building block in his regional development scheme. It features pedestrian pockets" within one-quarter of a mile of transit stops-an easy walking distance. These pockets contain mixed-use development including commercial centers and public servic es Farther out from the stations are secondary areas containing primarily housing. He believes automobile usage in such communities would be much lower than it is now, because more people would walk to activities. There would be both urban TODs and neighborhood TODs (for lower-density areas). Average residential densities of 10 units per acre would be maintained to support bus service, with higher densities to support rail transit. In other areas, he recommends net densities of 18 u n its per acre. Calthorpe would also like a 40-60 percent split between transit and auto usage, even though that split still implies a majority of travel by autos. His large r regional scheme shows transit stops one mile apart. Each TOD around such a stop contains 288.5 acres-a circle of 2,500 feet in radius. A Jcey element in the planning process is what fraction of the land should be used for housing At 40 percent, housing would consume 115.4 acres; at 65 percent, it would consume 187. 5 acres. Next, he as ks what average density of housing would prevail? Calthorpe suggests a range from I 0 to 25 units per acre, but in another section, he indicates that neighborhood TODs should have minimum densitie s of7 units per acre (5,600 persons per square mil e) and a minimum average of 10 units per acre (8 ,000 persons per square mile-just a bit higher than the city of Los Angeles). In urban TODs, the minimum density should be 12 units per acre, with an average of 15 units, and with maximums set by local plans. At 15 units per net acre, the gross density TRANSIT COOPERAnvE RESEARCH PROGRAM (TCRP/ HIO

would be 15,600 persons per square mile if the residential land coverage was 65 percent. Gross density would be 12,000 persons per square mile if residential coverage was 50 percent the coverage used to calculate other statistics in this paragraph. According to Calthorpe, secondary areas should have a minimum average density of 6 units per net acre, or 4,800 persons per square mile with SO percent residential land coverage. This, he says, should be the minimum pennissible density anywhere in the developed region Much of the book forth design guidelines for parks, commercial areas transit stops. and a set of specific projects developed by Calthorpe e m bodying his ideas.

The Cods of rcrwi-Revisited was a protective enclave requiring insulation from commerce work, and traffic, and held that the functional and literal center of a neighborhood should be an elementary school." The suburbanization movement also "liberated significant numbers of people from crowded, unhealthy living conditions ." But it created the following problems: (I) It raised the cost of homeownership and acceptable housing too high for many households; (2) It forced people to spend more and more time commutin g (this point is debatable] ; (3) It undermined the mobility of people who cannot afford cars or canno t drive them; ( 4) It created air pollution; (5) It absorbed attractive into urban uses, and (6) Most imponant of aU but most problematic-it undermined civic life. The main principles of the new urban ism, as he describes them are as follows: The center of each neighborhood should be defined by a public space and activated by locally oriented civic and commercial facilities. Each neighborhood should accom modate a range of household types and land uses. Cars should be kept in perspective. Architecture should respond to the surrounding fabric of buildings and spaces and to local traditions. New urbanists draw upon several past tradit ions including the City Beautiful and Town Planning movements. Calthorpe has written that in theory 2 .000 homes, a million square feet of commercial space, parks, schools and day care could fit within a quaner-mile wal.k of a station, or about 120 acres. The strategy of the new urbanists is to change local zoning regulations to force the adoption of their principles, or at least to permit them to be followed. Annotation' In fact, it has been difficult to implement TOD schemes, since most areas do not have rail transit systems. Some critics claim that the new urbanists emphasize visual style over planning substance. They claim that the large-scale proposals seem to continue sprawl, rather than change it. Moreover, the critics argue that the impact of the new urbanists approach will be minimal unless some type of regional governance is more widely adopted. Finally, the new have largely ignored the growing divisions of wealth and power among households. As Katz notes: "New Urbanism is a welcome step forward, but it is only a step."

accountability -for the success of their students." (81) It may be that the best direction for reforming the schools is to seek a diversity of providers that are publicly monitored. rather than a bureaucratic system controlled by the mandate s of a single government agency. What would a system look like in which a government did the steering and let many others do the rowing (82)? She advocates three major principles for radical refonn: Autonomy-Each school should control its own budget and hire (and fire) its own teachers and other personnel. Each should be tol d bow much money it has (based upon enrollments, p lus allow ances for disadvantaged students) and allowed to all ocate that money as i t sees fit-knowing that it would be rigorously audited by public officials. Choice-Teachers should be able to freely decid e where t hey will work, and students and parents should be able to decide where they want to send their ch ildre n to school. The centralized authorities should set standards for performance, periodically assess perfonnances of Annotations every school, and constantly infonn parents and the public of the results. Central author i ties would also oversee large capital improvements. negotiate union cont racts (without inhibiting schools from hiring whomever they wish). approve the creation of new schools, and audit perfonnance and finances. Schools that want to manage their own affairs should be allowed to conduct elections among staff and parents to become chartered schools, and immediately be given aut onomy. This would p e rmit success f u l schools to become s elfgoverning right away. A second element of the strategy would include contmcting out the management of several or many schools to specific organizations. A basic idea is to encourage as many new schools to be fanned as possible. A third element in the strategy is to provide means-t ested scholarships to poor students who could choose to use them in whatever schools they wanted. These would essentially be vouchers paid to the students or their parents not to the institutions themselves-thereby finessing the religious school issue. This procedure has been successfully adopted in some o t her programs around the country. TRANSIT COOPfi!ATIVf RESEARCH PROGRAM (TCRP) H .JO
