ECONOMIC ANALYSIS OF COORDINATED LINEAR INFRASTRUCTURE PROJECTS (CLIPS) Background Infrastructure and utility projects, such as roads, teleconununications lines, railways, and pipelines are typically developed with minimal coordination. This results in tedundant corridors, additional disruption to neighborhoods, and increased fragmentation of Florida's landscape and natural ecosystems. Multi-use corridors offer the potential to minimize community and environmenta l impacts and reduce overall project development costs. For example, an ongoing effort is underway to link Florida's narural areas via a network of green ways. Inevitably, large infrastructure projects must cross these green ways. Rather than disrupting a greenway in several locations, new utility and infrasuucrure projects and future extensions of existing utilities could be co-located in multi-use corridors, known as Coordinated Linear Jnfrastructute Projects (CLIPS). However, the benefits of co-location may be outweighed by the costs of rerouting a new facility or extension. or the cost of additional right-of-way in proximity to CLIPS corridors. To further explore this issue, this project was developed to involve in-depth analysis of the economic aspects of CLIPS and compare these results to the costs of traditional linear facilities development. Approach The study, funded by the F lorida Department of Transportation (FDOT), was conducted in collaboration with the Hillsborough River Greenways Task Force (HRGTF)a broad coalition of industry, environmental, gove .nnnent, and civic leaders. It was accomp lis hed using actual local data from environmental agencies, utility companies, and the F lorida Department of Transportation (FDOT). The objective was to e

FDOT (transportation infrastructure), and utilily companies (existing and proposed utilities). It was anticipated that the data would have been made available to the research team shortly after the project start date. Since most of the geo-data and the cost data were not available in a timely or completely adequate fonn from the contacted entities, the approach to the scope was revised during a discussion with representatives of HRGTF and FOOT District VD. At this meeting, held onFcbru;uy 16,2000, the(l) lack of depth and precision in the data and t h e (2) necessity to continue development of the CLIPS concept, with simplified analyses; was mutually acknowledged. The latter recOmmendation derived partially from the receipt of news that HRGTP would receiving a PhaseD grant from FHW A for, among things, a more detailed study (with refined data). Likewise, because the study corridor could be broken down into subsets in space and time to reflect more detailed geography. etc and then reassembled into the four "legs" of a CLIP, the simplified analyses were actually broad enough to embrace the general case of the problem at a later time. A detailed timeline for the entire project is shown in Appendix A. Evaluation of cartogr-phic data and the lintited amount of useful cost data available led the project team to elintinate aU but the most basic geographic analyses from the project and concentrate, more or less, instead on cost tradeoffs. To this end, the project team constructed a cost-comparison calculator using available cost survey data and hypothetical facility geometry to determine econontic measures of cost-benefits within a spreadsheet application. The general project research work plan included three major tasks: design of econontic analyses, including data collection, econontic analyses of case examples, and report composition. The fu:st part of this report focuses mainly on Task One, the basic design of the economic analyses and data collection. Following sections of this report are dedicated to detailed explanations of Task Two, Econontic Analyses of Case Examples, as selected cooperativel y by HRGTF and the project team. Analyses Strategy_ This task involved the design of analyses methodology for traditional Linear Infrastructure Projects (LIPS) in comparison to Coormnated Linear lnfrastrucrure Projects (CLIPS). The research team designed a protocol that combined project geometry from GIS data with project cost information obtained from utilities, permitting agencies, and FDOT. The initial data request included itentized costs for: planning, design and engineering, perntittioglmitigat ion, construction, rerouting, management, maintenance, and legal expenses. However, as previously mentioned, the project team elintinated all but tile most !>asic geographic analyses from the project and concentrated instead on cost tiadeoffs due to the lintited amount of useful geographic data available. Cost Data Collection Tbe majority of activity in Task One focused on data for evaluating representative CLIPS within the Hillsborough River Basin. A letter was drafted in August of 1999 and sent to representatives of panies with a strong interest in CLIPS or in the Hillsborough River Basin in general. These local representatives generally included utilities regulatory agencies, and municipalities. A sample cover letter and a copy of the data collection survey instrument are included in Auachment !. Completed data collection forms were received during the third and fourth quarters of the 1999 calendar year, as shown in Attachment 2. A table entry followed by a "Da t a Received" notation indicates that useable data was provided by the ent ity to the project team for the study. Enrries" labeled "Utilily Information Unavailable" were unable to provide.useabl e data to the project. team for the study. 2

A brief, preliminary examination of data obtained from SWFWMD showed a wide variance between physical features (based on USGS and/or SWFWMD authored maps) and transportation/ u tili t y map coverages (from other USGS data sets, the Census, and utility "CAD" systems). As presented in Figure 2, a common problem encountered in analyses i n which data from differ e nt sources or time epochs are mixed is the issue of .:egistration. Registration is a mapping, photographic. and printing concept referring to the alignment of spatially Identical points on different map, film, or print layers. The intermingling o f natural . transportation, and socioeconomic databases requires great care and forethought. particularly wlieo the interaction of man-made features (roads, utili t y corridors) and natura l features (river basins) joinUy determine the feasibility of a CLIPS. These mapping difficulties presented a major p roblem for the study b ecause the initial research design sought to determine the answers to three geog raphic questions in the context of CLIPS: To what extent does coordination of utility and transportation corridors occur spontaneoilsly, without formal intervention1 Could the cond itions in "spontaneously occurring" CLIPS serve as a gnide to the determination of a set of incentives that would selectively promote the development of other CLIPS? Could physical geogr aphy i dentify differences in the value of various types of natural habitat that might make some CLIPS corridors more desirable than others? Unfortunately. the lack of consisten t registration between the basic land cover, transportation, and demographic features of the study area precluded the investigation of these issues.

Since the map coverages were not suited to precise geographic analyses, the study team proceeded t o evaluate the economics of CLIPS through a more modest geographical depiction showing only basic geometry, and spreadsheet analyses. Cost data were combined with hypothetical measures of road, utility corridor, and river basin geography within a spreadsheet application that was used to evaluate the economics of C LIPS . INTRODUCTION TO THE OF CLIPS This portion of the Final Report addresses the development of a cost and feasibility calculation methodology and the development of a case example. It turns to the. use of a case example to establish the measurement and methodology of a process to judge the economic feasibility of CLIPS. The case example is a hypothetical corrido r a long the Hillsborough River near Interstate 75, just northea." of the USF Tampa Campus, with possible utility types included in the analyses. The report then turns to other scenarios involving the crossing of the HiUsborough River Basin, at CR-579, US-301, SR-39, and US-98. Methodology The project team used the analyses of a hypothetical crossing of a river liasin by transportation and utility corridors as a basic, interactive framework to develop a methodology for determining the feasibility of a CLIP. The conditions to establish the "threshold of feasibility' were numerous, as were the operational questions that they raised in the analyses. For example, would alignment of utilities as they pass through environmentally sensitive land be economically feasible? Moreover, if it were not feasible, under what conditions would realignment become economically feasible? The analyses had to provide a framework from which choices regarding overall corridor alignments could be made on a consistent basis, given the limitations on cost and geographic data. The project team utilized available data to calculate the per-mile costs of available utilities. The cO.ts included a breakdown of permitting, engineering, right-of-way, environmental mitigation and construction costs. The project staff established a hypothetical scenario with two adjacent projects. One project was an existing corridor that crossed environmentally sensitive land; the other was an adjacent planned project that similarl y traversed environmental l y sensitive land. TI1e question was, should the project planners considered co-locating the planned utility with the ex isting corridor cut through? Figure 3 illustrates tlle two coordinated projects. Under this hypothetical scenario, the question becomes, does the Planned Alignment (P A) cost more than the two Deviated Alignments (DA) and the Co-located Existing Alignment (CEA)? From the following simpl e equation members of the project staff were able to determine which set of conditions are necessary in order for this particular CLIP to be economically feasible. Ultimately, the equation is set up as such: (PA) < (DAtl+ (DA2)+(CEA). Using this formula, the project staff established the cost per centerline mile for each of the utilities for which information was available. Ge'neral PhysiogJ;aphy of the Subject Area As seen in Fignre 3, the planned and deviated alignments traverse a portion of the Hillsborough River's floodplain. The se nsit ive nature of these crossings had been an impetus for the analyses of this particular CLIPS study It may actually be better to consider this shallow,low-energy River as a "sand-bottomed stream" for surficial drainage, rather than a "true river" This factor becomes significant when determining construction costs. 5

The lowlands in proximity to the river channel are composed of d elicate vegetative, biological, and ecological communities. The ecosystem type of this region is consistent with those found in 'the southeastern United States, and especially those throughou t West-Central Florida. So i l series' of the study area for the most part include: Cbobee, lmoka lee, B a singer, HolopaW, Salnstila. These soils are associated with floodplains, drainage networks, and low-energy, fluvial systems. Other smaller soil units were identified. Their compositions and desc ript ions are consistent with those soil series' listed above.

sensitive land (PAl), 2) t h e segment that travels through the environmentally sensitive land (PA), and 3) the segment traveling away from environmentally sensitive land (PA2) towards the origi nally planned course. In this particu l ar example, there are savings froin ro-lochtiilg the utility to the FDOT corridor. As Table I iUustrates, the range of costs for the Planned Alignment is $2,425,920 to $8,406,000. The !'.mge of cost for co location of the utility i s from $579,020 to $1,92!,600. ln other words, the cost of co-locating the utility is less than the cost for the Planned Alignment inal
PAGE 12

Further ques t i ons, such as the foUowing, might arise: Would there still be right-of-way purohase costs? Would the permitting process be as extensive and expensive? What i s an acceptable cost reduction to savings ratio? Without estimating the reduced costs of relocating a utility into the shared corri dor, it is impossible to calculate the potential savings. To that end, the project staff establishe d a function al range of costs for the shared corridor Consequently, analyses were performed assuming that the shared corridor would add zero cost to the co-located utility. The results of t hese analyses, as found i n Tabl e 2, revealed a reduced cost and more savings. With the cost of the shared alignment eliminated, there are substantial savings if the planned utility were co located to share the established corridor. Thus, making it even more cost effective to co-locate the utilities within the existing right of-way Jn this case. the additional savings would be betw ee n $741,520 and $2.401,600. In reality, however, no t all of the costs associated with the co located crossing can be eliminated. For example, costs associated with construction still exist for both alignments at a minimum. This particular example reflec t s an economically feasible CLIP. However, several other alternatives with varying lengths and utilities are examined in this report to estab li sh clearer measures of feasibility. HRGTF may g enerally apply t hese fmdi ngs when considering whether a CLIP is applicable. TABLE 2.

The planned alignment (PA) variable appears to have the largest influence on the selection process. The greater the distance that must be ttaverscd across environmentally sensitive areas. the rnore likely the co: located alignment would be the most cost effective alternative, A long PA crossing provides for more flexibility in choosing a CLIP by allowing the CLIP to be located farther away if necessary or to be longer as it bisects environmentally sensitive areas . Application to Cas e Studies Within the Hillsborough River Basin The ultimate goal of this project was to apply the data, derived statistics, and methodology to highway and utility corridors that currently traverse the Hillsborough River Basin in an effort to demonstrate the extent to which CLIPS were economically justified. In addition to the prototype case example of Interstate 75 at the Hillswrough River, the project team and the HRGTF selected four additional study cilrridors consisting ofCR579, US-301, SR-39, and US98. Figure 4 shows the location of each of tllese corridors with respect to the Hillsborough River's main channel and generalized floodplain. The approximate length of each crossing, based on direct linear measurements using GIS tools, is also shown in th e figure. FIGURE 4: HILLSl!OROUGH RIVER BASIN "CLIPS" 0PPORTUNlTlES CLIPS Length (Milie$) 1 =us Z=O.SO 3 =2.50 4=0.15 5=2.15 . : C\Jrrert River Channel -Mo;or Roods In Table 5, the length of the Co-located Existing Alignmeot(CEAJ was measured for those selected crossings listed as shown in Figure4. Based on these lengths, the project team members concluded that the length of the Planned Alignment (P A) was the factor used to determine whether or not to continue with the PA or choose the CEA. Distances less than those given indicate that the PA should be chosen. For the distances greater than or equal to those in the table, the CEA should be chosen. 10

PAGE 15

The following assumptions were made t o clarify the model. PAl and PA2 were held constant at 0.5 miles DAl and DA2 were held constant at I mile. F or each measured crossing distance of the CBA, the crossing distance of the PA varied until the savings associated wit h each apprQached zero, or at least. a point at which a nominal cost was reached. Nore that t his is only one case. If the lengths of the planned and deviated approaches were allowed to vary along with the PA, th e ranges of marginal savings would vary widely. Therefore, it is safe to conclude that each PAJCEA combination would have to be examined individually. Environmental impacts should also be weighed t o det enni n e the most cost-cll'ective route. TABLE 5. CEA CORRIDOR (MILES) I-75 SR-39 ofCEA 1.25 ASSIImes distance ratio ofPAl/PA2:DAl/DA 2 remains co n s t a nt at 1:2 *For' distances greater than or equal to the table values, th e combined alignment, or CLIPS, is economically advantageous, with benefits that could be shared between the public and private sectors. If the distances are less than those in the t able, choose the planned alignment. Note that while not shown her e, multiuse corddors combining more than one utility may very w e ll pnoduc o additional variation in the cutoff distances of the PA due primarily to savings iri corridorland acquisition costs. Summpry a n d Conclusions This project established the basic methodology through which multi -use corridors could be examined to determine ifCUPS-Cooolinated Linear Infrastructure Projectswere economically feasible. It is genesally believed that environmentally sensitive and/or priStine landscapes should be protected and that social needs for mobility and public utilities be met as well. CLIPS appear to bean ideal solutiOD 10 the problem of reconciling these two seemingly incompatible v iewpoints. The following is a bri ef synopsis of both the strengths and weaknesses of the methndology developed in this research project. The length of the Planned Alignment (PA) or uncoordinated crossi11g of the environmentally sensitive area was of primary importance in determining whether or not a CLIP was feasible. As the length of the subject planned crossing, or alignment, increased, the associated financial cost(s) became greater due to such f actors as environmental mitigation, pennining, and legal costs Corridor geometry tended 10 be a decisive factor for coordination in a single corridor. Costs including legal expenses environmental mitigation, and right-Of-way acquisition for the approaches were difficult to determine because of tremendous variability in the historical record. Furthermore, this variability made precise record keeping and tabulation difficult for the very entities from which data was .Ought. 11

PAGE 16

The study uncovered a re l ationshi p between the acceptab l e distance from a CLIP and the original planned alignment, the length of the co-located portion of the CLIP. the lengths of the planned and deviated approaches, and the l ength of the planned alignment crossing tha t lent itsel f to simu l ation using a s implified spreadsheet model. T he economic analyses were able to determine decision v a lues or breakpoints for various combinations of planned and coloeated alignments. This required the !mposition. of strong assumptions about average c osts, limiting the role of highly vo latil e cos t s (such as lega l fees), and leve r aging the limited cost information provided. While the model incorporated in the study was simplified, it allowed the project team to produ ce results b a sed on a series of highl y plausible "what if'" scenari.os regarding geometry and utilit y types. Further work needs to be done in the future to collect more complete data and to reconfigur e the model to i n clude these n ew costs particu larl y if the prototype is to be refmed for actual projec t selec t ion. This economic study has demonstrated that under the a p propriate condit i ons a well-planned CLIP may very well prod uce economic as well as environmental benefits to be regarded as not only feasible, but a lso desirable. 12
