Trip Distribution and Assignment Trip distribution was performed for the site generated traffic for the evening peak hour r. of an average weekday (see Figure 2). The distribution was based on the directional distribution of the existing traffic during the peak hour. An assignment of the projected trips was performed for the site generated traffic during the evening peak hour (see Figure 3). The percentages of trips shown in Figure 2 were used to assign the estimated traffic volumes contained in Table 1 to the roadway network. To provide a conservative analysis, all of the trips were assigned to passenger vehicles, rather than to transit, bicycle, or pedestrians to provide a worst case estimate. IV. Existing and Projected Traffic Volumes Traffic volumes for the analysis were collected by WL Contractors and obtained from, "Operational Analysis, Timberline Road Extension and State Highway 14", prepared by the City of Fort Collins in May 1997. This report is a feasibility study for the construction �x of Timberline Road from Prospect Road to Summit View. Drive north of State Highway 14. The City is anticipating that Timberline Road will be constructed during 1998. In t light of the pending construction of Timberline Road, traffic volumes contained in Figures 5 and 7 of the report were used for this analysis. Turning movement count data was collected at the intersection where the frontage roads intersect Mulberry Street near the site, Lemay Avenue/Lincoln Avenue, Lincoln Avenue/Link Lane, and Link Lane/Magnolia Street (see Appendix A). Projected volumes for the Buffalo Run rs Apartment development and the Lincoln East PUD were obtained from a report prepared by Matthew J. Delich, P.E. for the City of Fort Collins. h s e 5 ► modify the signal phasing -at Lemay Avenue/Lincoln Avenue to add protected/permitted left turns for northbound and southbound traffic 12th Street - This proposed commercial local street will be constructed from Mulberry Street to Lincoln Avenue to provide access to Mulberry and Lemay Crossings and the light industrial/retail to the east. Near Lincoln Avenue, 12th Street will be built on the existing Block Drive right-of-way. A report was submitted to the City in July 1997 analyzing the type of access necessary at Mulberry Street/12th Street. The location of 12th Street will be where the frontage roads currently intersect Mulberry Street directly adjacent to the site. The report studied the following options: ► No access to Mulberry and Lemay Crossings ► Right-in/right-out access ► Right-in/right-outtleft-in access (3/4 access) ► Full access with signalization A recommendation was made in the report that the 3/4 access be used at this location. The frontage road on the north side of Mulberry Street will be realigned so that it intersects with 12th Street north of Mulberry Street/12th Street. City of Fort Collins traffic engineering staff supports this conclusion. Magnolia Street - This proposed collector without parking will extend from Lemay Avenue to 12th Street and provide access to the development. The } intersection with Lemay Avenue will be signalized and the other intersections LAI will be stop controlled. G II. Trip Generation Estimates of traffic generated by the development of the site were calculated and are contained in Table 1. Trip Generation rates were obtained from Trip Generation. 5th Edition (Institute of Transportation Engineers, 1991) and Trip Generation. February 1995 Update to the 5th Edition (Institute of Transportation Engineers, February 1995). Table 1 contains traffic volumes that are expected to be generated on a weekday, during the weekday morning peak hour, and during the weekday evening peak hour. Due to the wide ranging mix of uses that is being proposed for the development, a 10% internal capture rate has been applied to the trip generation estimates. This reduction reflects the probability that some drivers will visit more than one destination within the site. 4 V k, C. Existing and Proposed Uses in the Vicinity of the Site The area in the vicinity of the site is partially developed with light industrial and commercial uses, however, there is some development planned adjacent to the site. East of the site, the types of businesses are primarily light industrial and retail. West of the site, across Lemay Avenue, is the Link-n-Greens golf course. South of the site, across Mulberry Street, some small businesses exist. North of the site and directly adjacent to it, the Buffalo Run Apartments are being planned with 144 affordable housing units. On the north side of Lincoln Avenue across from Buffalo Run, the Lincoln East PUD is planned. No other proposed development in the vicinity of the site has been identified. . D. Existing and Proposed Roadways and Intersections There are two existing roadways and two proposed roadways that will provide access to Mulberry and Lemay Crossings. These roads are described below: Mulberry Street (State Highway 14) - Mulberry Street is a major east/west arterial roadway on the south side of the site. It has two through lanes in each direction with left and right turn lanes at signalized intersections. The roadway has paved shoulders and a depressed median. Traffic signals exist at Lemay Avenue and Link Lane. Frontage roads are located adjacent to both sides of Mulberry Street. Several improvements to the intersection of Mulberry Street/Lemay Avenue are being proposed by the developer. These improvements include: ► dual westbound left tum lanes ► one additional northbound through lane ► protected northbound right turn phase ► traffic signal modifications to accommodate the additional laneage and revised signal phasing Lemay Avenue - This arterial roadway borders the west side of the site. It currently has one lane in each direction with left turn lanes at signalized intersections. Southbound Lemay Avenue at Mulberry Street has two through lanes. Signalized intersections on Lemay Avenue adjacent to the site include Mulberry Street and Lincoln Avenue. Several improvements are being proposed on Lemay Avenue including: ► widen the roadway to two through lanes in each direction with a continuous accel/decel lane adjacent to the site ► signalize the proposed intersection of Lemay Avenue/Magnolia Street 3 N) Mag 14.00 Figure 1.

Introduction Development is being proposed on a currently undeveloped site on the northeast comer of Mulberry Street/Lemay Avenue (see Figure 1). Mulberry Street is a state highway with the designation SH 14, and Lemay Avenue is a city street. A traffic impact study, prepared by Krager and Associates, Inc., for the Mulberry and Lemay Crossings project was previously submitted in December 1996. Following a review of the study by the City of Fort Collins and Colorado Department of Transportation, the developer was asked to resubmit the study with an expanded study.area. A. Land Use, Site, and Study Area Boundaries This 40 acre site, located in the northeast part of Fort Collins, is currently undeveloped. There will be approximately 360,000 square feet of gross leasable floor area constructed. The development will consist of three discount stores, six specialty retail businesses, and three restaurants. Access to the site will be obtained at four intersections along Lemay Avenue, six intersections on the proposed 12th Street, and at the proposed intersection of Mulberry StreeU12th Street. Of the four access points on Lemay Avenue, there will only be one full movement signalized intersection at Lemay Avenue/Magnolia Street. A study area was established through discussions with the city staff that incorporates the site plus some key intersections adjacent it. The study area is bounded by Lemay Avenue on the west, Lincoln Avenue on the north, Link Lane. on the east, and Mulberry Street on the South (see Figure 1). Traffic operations will only be analyzed during the evening peak hour because an access study for Mulberry StreeU12th Street showed that the traffic volumes during the evening peak hour are greater than during the morning peak hour. B. Existing and Proposed Site Uses This undeveloped parcel of land will be divided into four lots for the purpose of development. The existing zoning for the site is planned business with a PUD condition. Development of the site will consist of approximately 360,000 square feet of gross leasable area for retail and restaurants. Types of retail will include three discount stores, including a 188,000 square foot discount/grocerystore, and six specialty retail businesses. Examples of specialty retail business include dry cleaner,. clothing store, hardware store, and florist. The restaurants will include three high-tumover sit-down restaurants. These types of restaurants. provide seated service and do not include fast food or drive through restaurants. 1 Executive .Summary Development is being proposed on a currently undeveloped site on the northeast comer of Mulberry Street/Lemay Avenue (see Figure 1). This 40 acre site, located in the northeast part of Fort Collins, is currently undeveloped. There will be approximately 360,000 square feet of gross leasable floor area constructed. The development will consist of three discount stores, six specialty retail businesses, and three restaurants. Access to the site will be obtained at four intersections along Lemay Avenue, six intersections on the proposed 12th Street, and at the proposed intersection of Mulberry Street/12th Street. Of the four access points on Lemay Avenue, there will only be one full movement signalized intersection at Lemay Avenue/Magnolia Street. A number of roadway improvements are being proposed in conjunction with the development of Mulberry and Lemay Crossings. These roadway improvements include: ► Construct dual left turn lanes westbound on Mulberry Street at Lemay Avenue. ► Add one northbound through lane on Lemay Avenue at Mulberry Street. Add a northbound right turn phase at Mulberry Street/Lemay Avenue. Construct right turn channelizing islands on all four comers of Mulberry Street/Lemay Avenue. ► Construct a 3/4 access at Mulberry Street/12th Street. Realign the frontage road on the north side of Mulberry Street at Mulberry Street/12th Street. ► Widen Lemay Avenue to two lanes in each direction with turn lanes at signalized intersections from Mulberry Street to Lincoln Avenue. ► Signalize Lemay Avenue/Magnolia Street. ► Modify the signal phasing at Lemay Avenue/Lincoln Avenue to provide protected/permitted left turns. ► Construct 12th Street from Mulberry Street to Lincoln Avenue to commercial r- local street standards. Construct Magnolia Street, a collector without parking, from Lemay Avenue to 12th Street. The vehicle miles of travel in the city are predicted to be reduced by about 17,500,060 miles annually because residents of northern Fort Collins will not have to drive to south Fort Collins to shop at discount retail stores. This reduction in annual vehicle miles of travel ini; udes approximately 8,500,000 less annual vehicle miles of travel on College Drive alone. r Mulberry and Lemay Crossings is being planned with pedestrians, bicyclists, and transit r riders in mind. An integrated system of sidewalks and bike paths will connect to the Poudre River Trail and existing walking paths. With transit stops planned along Lemay Avenue and within the development, shoppers will be encouraged to use alternate methods of transportation. 4 LIST OF TABLES Table Page Table 1.
