These left -turn lanes should be adjusted as traffic volumes change. At the Mulberry/Taft Hill signalized intersection, the northbound and southbound left turns share a lane with the through traffic. Since the Taft Hill green phase is greater than 50 percent of the cycle length and since the left -turning traffic is/will be low, the shared lane situation does not present an operational or safety problem. Should the Taft Hill through traffic and/or left -turn traffic increase significantly due to unforeseen circumstances, this shared lane situation may present concerns. Traffic should be monitored at this intersection. Impala Drive Traffic Comparing the traffic volumes on Impala Drive in Figures 1 and 2 indicates that the traffic volumes do not change significantly overall. There will likely be a net reduction in traffic volumes on a daily basis due to the elimination of the through traffic movement. "Cruising" traffic will also be eliminated due to the discontinuity of the street system. Conclusions Based upon these analyses, the following is concluded: - Operation at the key intersections is acceptable.. With the closure of Impala Drive to through traffic, operation at the key intersections will continue to be acceptable. • - At the LaPorte/Impala intersection, the westbound left -turn lane is recommended to be 200 feet long. This length should increase as the traffic volumes/school population increases. - Geometry at the Taft Hill/LaPorte and Taft Hill/Mulberry signalized intersections is adequate from an operational perspective. Consideration should be given to increasing the radius on the southwest corner of the Taft Hill/LaPorte intersection. However, this improvement will be difficult and expensive. - The Impala Drive traffic will decrease with the closure of this street near PHS. Table 1 shows the current peak hour operation at the three key intersections. Calculation forms are provided in Appendix A. All intersections operate acceptably with the current control and geometry (number of lanes). Table 2 shows the short range peak hour operation at the three key intersections, using the traffic volumes shown in Figure 2. Calculation forms are provided in Appendix B. All intersections will operate acceptably with the reassigned traffic that results with the closure of Impala Drive to through traffic. The operation is not significantly different than that shown in Appendix A. Table 3 shows the long range peak hour operation at the three key intersections, using the traffic volumes shown in Figure 3. Calculation forms are provided in Appendix C. Operation at all of the analyzed intersections continues to be acceptable. This indicates that the operational geometry at each intersection is adequate. Intersection Geometr Each intersection was evaluated concerning any geometric constraints or improvements that should be considered given the peak hour traffic projections. At the LaPorte/Impala intersection, the movement that impacts the public street system is the LaPorte westbound left turn to Impala. During the morning peak hour, the number of vehicles making this left turn is/will be significant. The current count is 259 vehicles during the morning peak hour. This is projected to increase to over 330 vehicles when the student population reaches 1800 at PHS. During other hours of the day, this left -turn movement is expected to be less than 100 vehicles. If the morning peak hour is considered to be the design condition, then this left - turn lane should be 270 feet long based upon the short range morning peak hour traffic. As the population of PHS increases, the length of this lane should increase as necessary. However, designing to a single peak hour is not usually appropriate. Therefore, it is recommended that the above length (2701) be factored by 0.75 to reflect a design hourly volume condition. This .results in a 200 foot westbound left -turn lane on LaPorte Avenue approaching Impala Drive. While the operations analysis indicates that the existing geometry is adequate .at the Taft Hill/LaPorte intersection, the eastbound to southbound right turn has a very small radius due to the guardrail protecting the irrigation ditch that crosses this intersection. Buses making this maneuver must encroach upon other lanes in the intersection. Increasing this radius will improve the ability to make this turn, however it will be difficult and expensive to make this improvement.

Specifically, these additional traffic analyses consisted of: - Operation of selected intersections with Impala Drive closed to through traffic (as proposed) and PHS student population at 1800. - Geometric evaluation at selected intersections. - Current and future traffic volumes along Impala Drive. Figure 1 shows traffic counts at a number of mid -block and intersection locations near PHS. The dates of the counts are also shown. Comparison of the counts indicates that there is a consistency in traffic volumes, even though the counts cover a four year period. This indicates that this area of Fort Collins is not a high growth area. The traffic volumes shown in Figure 1 are considered to be the base condition. Figure 2 shows the base condition traffic volumes with Impala Drive closed to through traffic. To obtain the peak hour traffic volumes shown in Figure 2, selected vehicle trips, as documented in the "Poudre High School traffic analysis," August 9, 1993, were reassigned to the street system. The traffic volumes shown in Figure 2 are termed "Short Range." Figure 3 shows future traffic volumes (approximately a year 2000 condition) with a student population of 1800 and a general increase in background traffic of 2 percent per year. Intersection Operation Three key intersections were evaluated using the volumes shown in Figures 1, 2, and 3, and using the current geometry at each intersection. These intersections are: 1) LaPorte/ Impala, 2) LaPorte/Taft Hill, and 3) Mulberry/Taft Hill.
