These values reflect a 2 percent increase in delay at this intersection with the current geometry. In the course of conducting these evaluations, it was determined that full development of Centerpoint Plaza (Buildings A, B, and C) would not meet the APF criteria. In fact, development of Buildings A and B would meet the APF criteria in the morning peak hour, but would not meet the APF criteria in the afternoon peak hour. In light of this, an assignment was conducted using just Building B. The trip generation for Building B is provided in Table 2. The total floor area in Building B is 27,306 square feet. As analyzed in this memorandum, the uses within Building B were 5000 square feet of general office, 20,306 square feet of warehouse, and 2000 square feet of indoor recreation. This trip generation was assigned to the Prospect/Timberline intersection using the accepted trip distribution shown in the cited TIS. The forecasted (2006) peak hour volumes are shown in Figure 3. Table 3 shows the intersection level of service and delay using the volumes shown in Figure 3. Calculation forms are provided in Appendix B. The increase in delay is 0.8 percent and 1.8 percent in the respective peak hours'. Based upon this analysis, it is concluded that Centerpoint Plaza, Building B will meet the APF criteria at the Prospect/Timberline intersection. If, after Building B was approved for development by the City of Fort Collins, Building A was proposed as a PDP or FDP to the City, an APF analysis would be required. That analysis, like the Building B analysis, would need to include the current traffic factored to reflect the analysis year plus all approved developments which are not built at the time of the Building A proposal. This would include Building B. From the foregoing analyses reflected in this memorandum, it is likely that Building A would meet the APF criteria. MEMORANDUM 0 c� 0 CC) cc TO: Kevin Frazier ' oo Dick Fisher, Cobalt Design -Build o 6 Louise Herbert, VF Ripley Q ED City of Fort Collins O p O U rn FROM: Matt Delich may% • o X < LL DATE: August 26, 2002 a UJ SUBJECT: Centerpoint Plaza Transportation Impact Study - Building J B Adequate Public Facilities Analysis (File: 0153ME07) • w > C) CV cc Q (D This memorandum addresses the adequate public facilities (APF) z T issues at the Prospect/Timberline intersection for Building B within aCenterpoint Plaza. The transportation impact study guidelines = rn indicate that significant impact is defined in Section 4.5.2.A.2 in iii the "Larimer County Urban Area Street Standards," as follows: "When w C7 o the background traffic conditions (without project traffic) causes N an intersection to fail the minimum acceptable level of service rl- standards; and when the project traffic causes more than a 2 percent N increase in the intersection delay." The "Centerpoint Plaza Transportation Impact Study," August 2001 demonstrated that all of the key intersections would operate acceptably with full development of Centerpoint ,Plaza in the short range (2006) future. Given this analysis timeframe, it was assumed that the Prospect/Timberline intersection would be improved beyond that which exists today. This analysis included a number of developments which have approved overall development plans, but no approved preliminary development plans or final development plans. The assumed improvements at the Prospect/Timberline intersection were reasonable for this analysis. W The original cited TIS used base (existing) traffic conditions n. z at the Prospect/Timberline intersection that were dated October 2000. The analyses contained in this memorandum use more recent traffic `¢ counts (supplied by the City) dated November 2001. These traffic Z counts are shown in Figure 1. These counts indicate that the U ZProspect/Timberline intersection is operating at level of service F J Z during both peak hours with the existing geometry. W o 0 a Since improvements to this intersection are not on a capital ¢ improvement program, City staff requested an APF analysis that • 0 CL included existing traffic factored to the year 2006 at 1.5 percent U) per year, plus known/approved projects that impact the subject a intersection. These projects are: Rigden Farm 6t" Filing, Spring F Creek Center, and Midpoint Self Storage. The base (2006) peak hour W 06 traffic at the Prospect/Timberline intersection is shown in Figure 0 2. The APF analysis must use the existing geometry at the subject F. a intersection. Table 1 shows the intersection level of service and cc delay using the volumes shown in Figure 2. Calculation forms are QH provided in Appendix A. Clearly, this intersection will operate C unacceptably with the existing geometry. In order to meet the APF
