CONCLUSIONS This study assessed the traffic impacts of the development of the Fossil Creek Business Park PUD and other uses on the short range (1997) and long range (2015) street system in the vicinity of the proposed development. As a result of this analysis, the following is concluded: - The completion of the Fossil Creek Business Park and neighboring land uses is feasible from a traffic engineering standpoint. The Fossil Creek Business Park Phase I will generate approximately 700 trip ends daily, and Phase II will generate approximately 880 daily trip ends. The adjacent other parcel will generate 90 trip ends daily. Based upon current traffic volumes and existing geometry/ control, the College/Fossil Creek intersection generally operates acceptably, except for sou£hbound left=turns from College to Fossil Creek. These movements operate at levels of service F during the afternoon peak hour. It was assumed that this signal would be modified to include left -turn phasing for College Avenue. By 1997, given development of Phases I and II of the proposed Fossil Creek Business Park and the other adjacent parcel, the College/Fossil Creek intersection is expected to operate at acceptable levels of service. - By 2015, with the projected traffic volumes, the intersection of College/Fossil Creek will operate acceptably. 5 I. INTRODUCTION This traffic impact study addresses the capacity, geometric, and control requirements at and near, the proposed Fossil Creek Office Park PUD (Cameron Office Park). It is proposed to be located west of South College Avenue across from Fossil Creek Parkway in Fort Collins, Colorado. During the course of the analysis, numerous contacts were made with the project owner (Lagunitas Fort Collins Inc.). Due to timing of this project, the Fort Collins Transportation Division could not guidelines. TThe study involved thehfoilowingtsteps: - Collect physical, traffic, and development data. - Perform trip generation, trip distribution, and trip assignment. - Determine peak hour traffic volumes. - Conduct capacity and operational level of service analyses on key intersections. The "G.T. Sanders Store PUD, Site Access Study," July 1995, and the "Huntington Hills Site Access Study," March 1994, were also reviewed as part of this analysis. II. EXISTING CONDITIONS r The location of the Fossil Creek Office Park PUD site is shown in Figure 1. Since the impact in the short range, as well as, the long range is of concern, it is important that a thorough understanding of the existing conditions be presented. Land Use In the recent -past; the-C-ity of-Fort_Collins has tended to grow predominantly to the south. Development along South College Avenue is expected to continue. This is evidenced by a number of retail developments (e.g. Webergs Furniture and Tynan Nissan) and residential developments (e.g. Huntington Hills and Ridgewood Hills). The center of Fort Collins lies to the north of the Fossil Creek Office Park PUD site. The adjacent land uses near the Fossil Creek Office Park PUD site are as follows: 1) to the west is the Burlington Northern Railroad track; 2) to the north is the Mill Brothers Landscape and Nursery; 3) to the east are commercial uses along College Avenue or vacant land; and 4) to the south is the existing Cameron Park Office Park. 1 N NO SCALE HORSETOOTH ROAD Roads The primary streets near the Fossil Creek Office Park PUD are College Avenue and Fossil Creek Parkway. College Avenue is a north -south street designated as a major arterial on the Fort Collins Master Street Plan. Its existing cross section in this area has two 12 foot lanes in each direction. There are designated left -turn lanes at appropriate locations or two way continuous left -turn lanes. There are shoulder areas between the. right through lane and the curb and gutter that serves as a right -turn auxiliary lane. The posted speed limit is 5.0 mph on College Avenue in this area. Sight distance is generally not a problem. Currently, intersections along South College Avenue are signalized at Harmony Road to the north and Skyway Drive to the south. According to the "South College Avenue Access Control Plan," a signal is expected at Fairway Lane in the future. Fossil Creek Parkway is an east -west street that serves commercial and residential uses on the east side of College Avenue and office/commercial uses on the west side of College Avenue. To the west of College Avenue, Fossil Creek Parkway leads directly into the Cameron Park Office Park. This is a two-lane roadway. East of College Avenue, Fossil Creek Parkway provides access to the residential area known as Fossil Creek Meadows. Fossil Creek Parkway is a two-lane roadway with a landscaped median. The speed limit is posted at 25 mph. Coronado Court is a two lane local street, which will provide direct access to Phase I of the proposed project. This roadway connects to the north/south Frontage Road, which parallels College Avenue. The Frontage Road currently exists north to Coronado Court and south, just past Cameron Drive. Cameron Drive is a two-lane local street, which currently serves Cameron Park and would provide access to Phase II of the proposed project. Existing Traffic Weekday morning and afternoon peak hour traffic data was synthesized based upon traffic count data from 1993. The 1993 through traffic on College Avenue was factored upward by 2 percent to reflect growth in the last two years. The peak hour turning movements are shown in Figure 2. All raw traffic data is presented in Appendix A. Existing Operation Using the traffic volumes shown in Figure 2, the College/ Fossil Creek intersection operates as indicated in Table 1. Calculation forms for these analyses are provided in Appendix B.

As indicated in Table 1, the intersection is currently operating at acceptable levels of service during most of the day. Acceptable level of service is defined as level of service D or better. However, the intersection operational analysis indicated that, during the evening peak hour, the southbound left -turn is approaching the need for a separate left -turn phase. For the future traffic scenarios, it was assumed that left -turn phasing on College Avenue would be in place. III. PROPOSED DEVELOPMENT The Fossil Creek Office Park PUD is an office park development, proposed to be located at the west of South College Avenue across from Fossil Creek Parkway in Fort Collins. Figure 3 shows a schematic of the site plan of the Fossil Creek Office Park and some adjacent properties. The proposed project would be completed in two phases: Phase I would consist of 48,800 square feet of office park use, and Phase II would consist of 61,000 square feet of office park use. As shown on Figure 3, Phase I would have access from Coronado Court and Phase II from Cameron Drive. The potential for growth on another parcel near the project site was also accounted for. There is currently a vacant parcel off of the Frontage Road to the south of Phase I. It was assumed that this could potentially develop as 6,100 square feet of office. Trip Generation Trip generation is important in considering the impact of a development such as this upon the existing and 'proposed street system. A compilation of trip generation information was prepared by the Institute of Transportation Engineers and is presented in trips that would be generated by the proposed uses at this site. Table 2 shows the expected trip generation on a weekday and a weekday peak hour basis. The Business Park Code (770) was used to estimate the trip generation for the Fossil Creek Office Park. Trip Distribution Directional distributions were determined for the land uses considered in thi: study. This distribution considered trip attractions and productions in the Fort Collins area, and existing travel patterns in the area. The trip distribution used in the short range analyses was 75% to/from the north and 25% to/from the south.. The trip distribution used in the long range analyses was K I a q O ;:,.;:,� a«...,�.,,,.,, .. . ........ +"+ Phase 2 :'.`. .. ♦....q ♦ .r .—+ . . ♦ ♦.� r �♦ ♦ . . . . a . . a .♦ , , • , , ..«.♦al ,..,♦..I'� �....♦ 1 l.Y.........1 , .......� ♦.,..,.f . ..,.... .�._f♦ . . . . . . 1�. ♦ . ♦ . .

Trip Assignment Trip assignment is how the generated and distributed trips are expected to be loaded on the street system. The assigned trips are the resultant of the trip distribution process. Figures 4 and 5 show the assignment of the generated trips from Phase I and Phase II, respectively. Figure 6 shows the long range assignment of the site generated traffic with full development of all the parcels considered in this study, given the change in trip distribution discussed earlier. Figure 7 shows the morning and afternoon weekday peak hour traffic from Phase I plus background traffic in the short range future (1997). Background traffic on College Avenue for 1997 was determined by factoring the 1995 traffic by 1.7 percent per year. This factor was determined based upon historic traffic growth and information contained in the "North Front Range Regional Transportation Plan," October 1994. Figure 8 shows the short range future (1997) morning and afternoon weekday peak hour traffic from the proposed project, both Phase I and II, plus background traffic, and estimated traffic from the adjacent vacant parcel mentioned earlier. Figure 9 shows the morning and afternoon weekday peak hour traffic in the long range future (2015). Background traffic for the year 2015 was determined using other traffic studies for projects in this area and the "North Front Range Regional Transportation Plan." The forecasts shown in Figure 9 give a reasonable representation of nearby development. When actual development proposals are put forth for other properties, additional traffic studies should be performed. IV. TRAFFIC IMPACTS AND Operation Analysis Capacity analyses were performed on the College/Fossil Creek intersection, which provides access to the proposed Fossil Creek Office Park for both the short range (1997) and long range (2015) traffic conditions. Using the traffic volumes shown in Figure 7, the College/ Fossil Creek intersection operates in the short range future, with Phase I, as indicated in Table 3. Calculation forms for these analyses are provided in Appendix D. As indicated in the table, it is anticipated that this intersection will operate at acceptable 4
