The sum of the peak hour traffic from both parcels was assigned to the site access. Short range traffic forecasts were developed for eastbound Harmony Road from recent peak hour counts and a recent transportation impact study .for the Front Range Baptist Church/School Expansion. The short range (2010) total peak hour traffic forecast at the site access is shown in Figure 3. As a right-in/right-out access, the operation of the right -turn exits from this site will be at level of service C in the morning and afternoon peak hours. Calculation forms are provided in Appendix A. This as acceptable operation. The forecasted right -turning volume at the access to Harmony Road will exceed the threshold requiring a right -turn auxiliary lane. Harmony Road is classified as a major arterial street with a design speed of 50 mph (posted speed is 45 mph). At the design speed, the right -turn lane should be 435 feet, including a bay taper at 200 feet. Available design drawings prepared by S.A. Miro, Inc. indicate a right -turn lane of 420 feet. This is slightly less than the requirement, but in excess of that needed at the posted speed of 45 mph (375 feet). It is concluded that the current design will function efficiently and not be detrimental to the public health, welfare, and safety. A detached sidewalk will be constructed along the Harmony Road frontage of this property along with an internal sidewalk system. It will connect to. the existing sidewalk to the east. This will provide pedestrian access to the Harmony/Hogan-JFK intersection where there are crosswalks. The primary pedestrian destination will be to the commercial area to the north (Harmony Centre). Appendix B contains a Pedestrian LOS Worksheet. The pedestrian -level of service will be acceptable. There is one bicycle destination within 1320 feet of this site. It is the Harmony Centre commercial area to the north. The shoulders on Harmony Road and the bike lanes on JFK Parkway will provide acceptable bicycle level of service for the Fort Collins Supportive Housing development. Transfort Route 1 passes by this site (eastbound) on Harmony Road. The nearest stop, on JFK Parkway north of Harmony Road, is within 1320 feet of this site. The transit level of service will be acceptable. It is concluded that the Fort Collins Supportive Housing development will have a minimal traffic impact on the area streets. The proposed right-in/right-out access will operate acceptably. The proposed access will also serve the property to the west. Future development of the property to the west will contribute most of the vehicular traffic at the proposed access. The pedestrian, bicycle, and transit level of service will be acceptable. DELICH ASSOCIATES Traffic & Transportation Engineering 2272 Glen Haven Drive Loveland, Colorado 80538 Phone: (970) 669-2061 Fax: (970) 669-5034 r MEMORANDUM �QO REG/s TO: Bryan Clerico, S.A. Miro, Inc. C 4aLi Eric B.racke, Fort Collins Traffic Engineer y ^ Ted Shepard, Fort Collins Planning Departments FROM: Matt Delich DATE: February 28, 2007 SUBJECT: Fort Collins Supportive Housing Transportation Impact Study (File: 06118ME01) This memorandum constitutes the Transportation Impact Study (TIS) for the proposed Fort Collins Supportive Housing development. It is located south of Harmony Road, west of Hogan Drive. The site location is shown in Figure 1. The scope of this TIS was discussed with Eric Bracke in late 2006. Due to the -low trip generation, a memorandum was requested that addressed the trip generation, the access to Harmony Road, and the alternative transportation modes. A site plan is shown in Figure 2. A right-in/right-out access is proposed on the south side of Harmony Road approximately 740 feet west of Hogan Drive. There is a raised median in Harmony Road between South College Avenue and JFK Parkway. The Fort Collins Supportive Housing is a building with 23 apartments for physically disabled people. This type of use is not listed in Trip Generation, 7�1' Edition, ITE, but it would likely have similar trip characteristics as a senior housing facility. As senior attached housing, 23 units will generate 80 daily trip ends, 2 morning peak hour trip ends, and 3 afternoon peak hour trip ends. As a conventional apartment, 23 units will generate.160 daily trip ends, 11 morning peak hour trip ends, and 14 afternoon peak hour trip ends. While the relative difference is substantial (2-5 times increase), the absolute difference is small, especially during the peak hours. Therefore, for analysis purposes, the higher apartment trip generation was used. The proposed access to this property will also serve the property to the west. This area is designated as "Basic Industrial and Non - retail Employment Activity Center" in the Harmony Corridor Plan. Using a floor area ratio of 0.30, and a conservative mix of allowed uses on this parcel (professional office, medical office, and sit-down restaurant), the trip generation for this adjacent parcel was estimated at: 1700 daily trip ends, 149 morning peak hour trip ends, and 170 afternoon peak hour trip ends. Note that the trip generation of the land uses on the adjacent parcel are significantly higher than
