This variance will not be detrimental to the public health, welfare, and safety; will not reduce the design life of improvements; and will not cause the City of Fort Collins additional maintenance costs. CONCLUSION The trip generation for the proposed Bucking Horse development (built and not built) will be less than that shown in the JFPTIS, July 2001. A variance to the intersection sight distance criteria for the proposed Jessup Farm access is requested. Do not hesitate to contact me if you have questions or desire additional information. --/I L--DELICH Bucking Horse Trip Generation Analysis & Variance Request, March 2012 _7,/ ; r-ASSOCIATES According to one of the engineers on the committee that prepared the LCUASS document, this basis was selected to keep traffic moving on the major street at a constant rate with no slow down due to side street traffic. It assumes that the driver entering the major street will only enter the major street when the approaching is at or beyond 1030 feet from the access location. This 'is not practical, since the driver entering the major street cannot possibly determine a distance of 1030 feet. Also, based upon experience, the driver of the vehicle entering the major street will likely select a gap at less than 1030 feet. This was recognized, and in the current (2011) edition of A Policy on Geometric Design of Highways and Streets, AASHTO has eliminated the basis of intersection sight distance described above. The time gap for 1030 feet is 14.0 seconds at the 50 mph design speed. This gap is more than 7 seconds longer than that used in determining the operational level of service in the Highway Capacity Manual. The gap used for sight distance determination should be similar to that used in the operations analyses. It is recommended that Figure 7-16, LCUASS be updated to reflect the most recent AASHTO design standards. Since that update is not likely to occur prior to the submission of the Bucking Horse development proposal, this variance to the intersection sight distance standard is submitted. Based upon the 2011 AASHTO design standards, please consider the following: Passenger Car Vehicle: Driver eye height - 3.5 feet Object height - 3.5 feet Design speed - 50 mph Time gap - 6.5 seconds Grade adjustment - 1.1 Intersection sight distance - 530 feet Combination Truck Vehicle: Driver eye height Object height Design speed Time gap - 7.6 feet - 3.5 feet - 50 mph - 10.5 seconds Grade adjustment 1.1 Intersection sight distance - 855 feet The above intersection sight distance criterion were evaluated at the proposed access to the Jessup Farm parcel. The combination truck criteria were determined to be the most critical. The evaluation indicated that there was adequate sight distance to the south from the proposed access location. —//`L—DELICH Bucking Horse Trip Generation Analysis & Variance Request, March 2012 —7 /. rASSOCIATES The trip generation table from the "Bucking Horse Transportation Impact Study' is also provided in Appendix B. The trip generation for the Bucking Horse development (excluding the built portion) is: 5850 daily trip ends; 504 morning peak hour trip ends; and 621 afternoon peak hour trip ends. The total trip generation for the Bucking Horse development (built and not built) is: 9414 daily trip ends, 778 morning peak hour trip ends, and 966 afternoon peak hour trip ends. It is concluded that the trip generation for the entire Bucking Horse development (built and not built) is less than that shown in the JFPTIS. Therefore, the existing overall development plan transportation impact study is valid. Due to the age of the JFPTIS, a new TIS was prepared. JESSUP FARM ACCESS A new access is proposed to the Jessup Farm parcel of the Bucking Horse development. This access is intended to be right-in/right-out. It is proposed to be located approximately 1000 feet north of Blackbird Drive (on -centers). This access will serve the uses within the Jessup Farm parcel. The proposed land uses are commercial and industrial . The vehicle type will primarily be passenger car, although there will be some single unit and combination trucks. As reported in the "Bucking Horse Transportation Impact Study," this access will not require a right -turn deceleration lane. However, as with the other accesses along the east side of Timberline Road, provision has been made for the three northbound through lanes that are shown on the Fort Collins Master Street Plan. As long as there are two functioning northbound through lanes, the right -most lane can be striped as a right -turn lane. This right -most lane will become a combined through/right-turn lane when Timberline Road is expanded to the six -lane cross section as shown on the Fort Collins Master Street Plan. The proposed Jessup Farm access is at/near the bottom of a grade along Timberline Road. The grade is roughly 4.25%. In light of this, an intersection sight distance evaluation was conducted. The design speed of Timberline Road is 50 mph (posted at 45 mph). According to Figure 7-16, "Larimer County Urban Area Street Standards (LCUASS)," the intersection sight distance for.this proposed access is 1030 feet to the south along Timberline Road for a passenger car vehicle at < -3% grade. This sight distance cannot be achieved for the proposed access. In light of this, a variance to this standard was prepared. Figure 7-16, LCUASS, was developed using A Policy on Geometric Design of Highways and Streets, 1990 (AASHTO). The basis of this distance (1030 feet) is: if the driver of a vehicle entering the major street sees an approaching vehicle at this specific location (1030 feet away); and the approaching vehicle is at the design speed; and the entering vehicle accelerates at a normal rate; then the approaching vehicle will not be required to slow down at all before overtaking the entering vehicle on the major street. ---/I LDELICH Bucking Horse Trip Generation Analysis & Variance Request, March 2012 7-,f r-ASSOCIATES DELICH ASSOCIATES Traffic & Transportation Engineering�'� 2272 Glen Haven Drive Loveland, Colorado 80538 Phone: (970) 669-2061 Fax: (970) 669-5034 �r r MEMORANDUM TO: Gino Campana, Bellisimo, Inc. City of Fort Collins FROM: Matt Delich DATE: March 30, 2012 SUBJECT: Bucking Horse ODP trip generation analysis & variance request (File: 1214ME01) This memorandum provides a trip generation comparison of the proposed Bucking Horse development versus the overall development plan (ODP) for the same property, formerly known as the Johnson Farm Property. The scope of this exercise was discussed with Ward Stanford, Fort Collins Traffic Operations. This memorandum also discusses the additional proposed access to the north parcel within the Bucking Horse development. This parcel is known as the Jessup Farm. In addition to this memorandum, a full transportation impact study was prepared for the Bucking Horse development. TRIP GENERATION The "Johnson Farm Property Transportation Impact Study (JFPTIS)," dated July 2001, established the trip generation for the overall development plan for this property. The site plan and trip generation table from the JFPTIS is provided in Appendix A. The approved overall development was shown to generate: 11,947 daily trip ends, 934 morning peak hour trip ends, and 1216 afternoon peak hour trip ends. The Bucking Horse Master Plan is provided in Appendix B. This is the same property as the Johnson Farm Property. A portion of this development has been constructed and is occupied. These are the single family lots and townhome portion (known as Sidehill) in the northeast quadrant of the Timberline/Drake intersection; and a portion of the single family area, north of Nancy Gray Avenue. Using Trip Generation, 8th Edition, ITE as a reference, the calculated trip generation for this built portion is: 1) Sidehill - 2944 daily trip ends, 224 morning peak hour trip ends, and 282 afternoon peak hour trip ends; and 2) Single Family Area - 620 daily trip ends, 50 morning peak hour trip ends, and 63 afternoon peak hour trip ends.
