Rub ., P.E. ! �g • DLR/wc ti•. ,% Enclosures: Table 1 Figures 1-3 Traffic Counts Computer Analyses \\Server\d\LSC\Projects\2001\011150\Report\F-PPS.wpd Mr. Jim Hillhouse Page 2 September 18, 2001 day traffic volumes as well as weekday morning and evening peak -hour traffic volumes expected to be generated by the proposed development. As shown in Table 1, the proposed development is expected to generate 482 daily vehicle -trips. Of this total, 40 trips will take place in the morning peak -hour (21 entering and 19 leaving) while in the evening peak -hour the number of trips is expected to be 43 (16 entering and 27 leaving). Being located next to the Colorado State University campus, some of these trips will probably not be vehicular trips. Some of the residents of the apartments will probably walk. Therefore, what is presented here is the worst case scenario. It is assumed that 20 percent of the traffic visiting the proposed development will come from the east and south, ten percent will access the site to and from the west, and the remaining 50 percent will access the site to and from the north. Figure 3 depicts the assignment of site - generated traffic at the intersection of College Avenue and Laurel Street based on the peak - hour traffic generation information contained in Table 1 and the distribution percentages discussed earlier. The specific phasing for the intersection of College Avenue and Laurels Street is being used to conduct this assessment. The average cycle length is approximately 100 seconds with 25 seconds devoted to Laurel Street and 75 seconds devoted to College Avenue. All approaches have a protected phase; however, during the field inspection, it did not appear that the arrow was working for Laurel Street. Northbound and southbound traffic on College Avenue begins the cycle. This runs for 45 seconds. The next phase lasts for 20 seconds and is devoted to only northbound traffic. The last phase for traffic on College Avenue is for southbound left - turning traffic and it lasts for ten seconds only if there is a vehicle in the turn lane. The remaining 25 seconds of the total cycle is devoted to traffic on Laurel Street. None of this phase is allocated to left turning traffic. Based on this information, the morning peak -hour operates at a good Level of Service (LOS "C") with an average vehicle delay of 22 seconds per vehicle. The evening peak -hour operates at an acceptable Level of Service (LOS "D") with an average vehicle" delay of about 40 seconds. / When traffic from the proposed development is added to the existing background peak -hour traffic volumes, there is no change in the Level of Service for either the morning or evening eak-hours. The average delay increases by less than one second per vehicle. Based on our analysis, the traffic impacts from the proposed Poudre Property Services develop- ment are minor and can be easily accommodated by the existing roadway system.

September 18, 2001 Mr. Jim Hillhouse Hillhouse Architects 8899 Gander Valley Lane Windsor, CO 80550 Re: Poudre Property Services Fort Collins, Colorado (LSC #011150) Dear Mr. Hillhouse: LSC Transportation Consultants has completed the analysis of the traffic impacts of the proposed Poudre Property Services development located at the southeast corner of the inter- section of College Avenue and Laurel Street in the City of Fort Collins, Colorado. The site already has a building located on it. This building is going to be removed and replaced with a 21,000 square -foot, mixed use, three-story building. Figure 1 depicts the location of the site with respect to the surrounding roadway system. The City of Fort Collins was contacted to determine what needed to be included in the analysis. After discussing the proposed development with Erik Bracke, it was agreed that an analysis of the existing signalized intersection at College Avenue and Laurel Street was all that would be needed. The analysis would assess the performance of this intersection with and without the traffic from the proposed development. Existing morning and evening peak -hour traffic counts were collected at the intersection of College Avenue and Laurel Street. The raw traffic count data is attached to this report. Figure 2 depicts the existing traffic volumes as well as lane geometry for this signalized inter- section. The existing site has two ways for traffic to enter and leave it. There is a right-in/right-out access point onto College Avenue and an access from the alley. The alley access leads to Laurel Street which is about 100 feet to the north. No changes are proposed to these two access points. The proposed development, as currently envisioned, is to contain 20 apartments, 4,700 square feet of retail development, and 12,500 square feet of general office development. Based on this information and the trip generation rates published by the Institute of Transportation Engineers (ITE) in Trip Generation, 1997, Table 1 displays the estimated average annual week-
