N Al Hauser, Architecture One O o Ted Shepard, Fort Collins Planning Department O M Rick Ensdorff, Fort Collins Transportation Division o From: Matt Delich z 3 `y > Date: October 25, 1991 O J • Subject: Taco Bell Enlargement Site Access Study update z (File 9041MEM1) w a z Taco Caliente, Inc. is proposing to enlarge their store zat the College/Prospect intersection in Fort Collins by remodelling an existing house located adjacent to the existing m M Taco Bell store at the corner. A similar proposal was made M in December 1990, except that the existing house would be razed and a new structure would be built. A traffic study of the previous proposal was prepared and submitted as "Taco Bell Enlargement Site Access Study," December, 1990. This memorandum is an update of that site access study as requested by the Fort Collins Planning Department. In the 1990 proposal, the restaurant was proposed at 2650 square feet. The remodelled house is proposed to be approximately 2900 square feet. A single lane drive through is also proposed at the new store. The earlier proposal indicated that during peak restaurant hours, a double lane drive through would be utilized. The larger restaurant coupled with the single lane drive through would likely offset Z each other with regards to trip generation. Taco Caliente w projects that restaurant traffic will likely increase by 25 Z percent., It is concluded that the trip generation used in the z previous traffic study should be used for this submittal also. u.i a J > The site layout of the 1991 plan is similar to the 1990 plan with regards to the location and function of driveways. s o The traffic volumes and operation at the Taco Bell restaurant cD are reflected in the site access study submitted in 1990. It W ¢ is concluded that the "Taco Bell Enlargement Site Access o a Study," December, 1990 addresses the traffic concerns as z voiced by the City of Fort Collins staff. A copy of the Executive Summary is attached to this memorandum. A design change was made at the College Avenue South w Access. This access functions as a right-in/right-out Fdriveway. The 1990 proposal showed this access with a standard driveway design, no curb return radius. This is the standard for driveway accesses. The 1991 proposal shows this access with curb returns. The proposal shows a curb return radius of 10 feet. This radius can increase to 15 feet with no impact on the parking lot layout. The access is proposed to be 28 feet wide curb to curb. The curb return design allows vehicles to exit College Avenue more quickly and safely. (Source: Transportation and Land Development, Stover/Koepke, ITE, 1988, pages 146-151.) It is concluded that a curb return design will provide for safer, more efficient exits from College Avenue. This will, in turn, improve the operation on College Avenue compared to conventional driveway access design. EXECUTIVE SUMMARY Taco Bell has proposed to build a larger restaurant on their existing site, located east of College Avenue and north of Prospect Road in Fort Collins, Colorado. This traffic impact study involved the steps of trip generation, trip distribution, trip assignment, capacity analysis, traffic signal warrant analysis, traffic signal progression analysis, and accident analysis. This study assessed the traffic impacts of an expansion of the Taco Bell restaurant on the adjacent streets. As a result of this analysis, the following is concluded: - The enlargement of the Taco Bell restaurant is feasible from a traffic engineering standpoint. It is expected that approximately 2000 trip ends will be generated at this site on a typical weekday. Some of these trips will be from the background traffic already passing by this site. - Using the existing peak hour traffic volumes and geometric improvements proposed under the Fort Collins Choices 95 Program, acceptable operation exists at the College/Prospect signalized intersection. It is recommended that a single southbound left -turn lane be constructed on College Avenue rather than double left -turn lanes as shown in the Choices 95 plans. The existing Taco Bell accesses to College Avenue operate acceptably. The existing Taco Bell access to Prospect Road experiences considerable delay and safety concerns for left -turn ingress and egress. It is recommended that the Prospect Road access be restricted to right-in/right-out. As part of improvements to the College/Prospect intersection, the City of Fort Collins is designing a median on the east leg of Prospect Road that will extend through the alley and assure the good operation of the right-in/right-out access on Prospect Road. It is recommended that a westbound right -turn lane be built on Prospect Road between the - — Taco Bell access and College Avenue. - With the Choices 95 improvements (single southbound left - turn lane) and the recommended westbound right -turn lane, the College/Prospect signalized intersection will operate acceptably with future traffic volumes. The proposed driveway accesses will operate acceptably as proposed. With the recommended traffic control and geometrics, a safer situation will exist and the accident rate should be minimal for an urban condition.
