In the afternoon peak hour, the overall calculated delay at the LemayNine intersection is between 42.0 seconds and 45.8 seconds with the an incremental trip distribution of 5 — 20 percent to/from the north on Lemay Avenue. In the afternoon peak hour under the background traffic condition and under all trip distribution scenarios, the westbound left - turn movement will operate at level of service F. The calculated delay for this movement remains the same under all analysis conditions. Summary With the citizen suggested trip distribution of 10-20 percent to/from the north on Lemay Avenue, there will not be an APF issue at the LemayNine intersection. The overall level of service in the afternoon peak hour remains at LOS D. In the afternoon peak hour, the overall calculated delay increases from 42.0 seconds (5% to/from north) to 45.8 seconds (20% to/from north). This is a modest increase in delay. J/LDELICH Capstone Cottages, November2015 -71 [—ASSOCIATES , DELICH ASSOCIATES Traffic & Transportation Engineering 2272 Glen Haven Drive Loveland, Colorado 80538 Phone: (970) 669-2061 Fax: (970) 669-5034 "71 r MEMORANDUM TO: John Acken, Capstone Collegiate Communities Linda Ripley, Ripley Design City of Fort Collins FROM: Joseph Delich DATE: November 9, 2015 SUBJECT: Capstone Cottages Additional Information (File: 1495ME03) This memorandum addresses comments given at the neighborhood meeting with regard to the "Capstone Cottages Transportation Impact Study (CCTIS) dated March 2015. The CCTIS had a trip distribution of 5 percent to/from the north on Lemay Avenue. This trip distribution was deemed to be appropriate. The citizen comment suggested that the trip distribution to/from the north on Lemay Avenue should be between 10 and 20 percent of the Capstone Cottages site generated traffic. The trip assignment of the Capstone Cottages through the LemayNine intersection was increased to 10, 15, and 20 percent in the morning and afternoon peak hour$. Operational analyses were performed at the LemayNine intersection using the trip distribution changes. Table 1 shows the short range (2019) peak hour operation at the LemayNine intersection for the following conditions: 1) Background (without the project); 2) Total traffic at a trip distribution of 5 percent to/from the north; 3) Total traffic at a trip distribution of 10 percent to/from the north; 4) Total traffic at a trip distribution of 15 percent to/from the north; and 5) Total traffic at a trip distribution of 20 percent to/from the north. LemayNine Adequate Public Facilities Proposed developments in Northeast Fort Collins are required to address the operation at the LemayNine intersection. This intersection has operational and geometric constraints that may create an adequate public facilities (APF) issue. Succinctly, if this intersection does not meet the overall level of service (LOS) criteria, then a development may add traffic such that the overall intersection delay is not increased by more than 2 percent over the base condition. The intersection falls under the operational criteria of "commercial corridor." In this area, acceptable operation at signalized intersections during the peak hours is defined as level of service D or better overall for the intersection. Table 1 indicates that the LemayNine intersection meets the overall level of service criteria. Therefore, there is not an APF issue at this intersection under all of the trip distribution scenarios.
