Primary access to the project site will be from both Prospect Road and Lake Street. Each of these is described below: • Prospect Road is a four-lane east-west arterial street. The current speed limit is 35 mph. A number of improvements have been made on the north side of Prospect to support the West Central Neighborhood Plan, March 17, 2015. This Plan calls for a 10-foot shared bicycle/ped path. This path is part of the proposed Haven Apartments project and has been installed by other projects along Prospect. Within the study area Prospect Road provides access primarily to the adjacent residential uses, Colorado State University (CSU) and some commercial. The City anticipates a new Pedestrian Signal on Prospect between Shields Street and Whitcomb Street. The exact location and implementation are currently being worked on. • Lake Street is a two-lane east-west collector street. The speed limit is posted at 25 mph. There are on-street bike lanes and sidewalks on both sides of Lake Street. This roadway serves primarily traffic related to CSU. Figure 1 – Overall Site Location HAVEN APARTMENTS – TRAFFIC STUDY CITY OF FORT COLLINS ROLLINS CONSULT LLC AUGUST 28, 2019 2 Figure 2 – Detailed Site Location Provided by Russell + Mills Studios PROJECT DESCRIPTION The proposed Haven Apartments will provide 54 student housing units in a new multi-story building and two existing homes. A detailed site plan is provided on Figure 3. As shown, vehicular access to the site will be provided from/to Prospect Road at a right-in/right-out only drive. Pedestrian and bicycle access will be from Prospect Road and via a pedestrian/bicycle easement that was created by the Apex Apartments and connects to W Lake Street. The access to W Lake Street will also serve as an emergency access. Vehicular parking will be provided directly adjacent to the two existing houses (Buildings 2 and 3) and on the ground floor level of the new multi-family building (Building 1). Bicycle parking is provided in the ground floor enclosed parking area and also to the west of the existing house (Building 2). HAVEN APARTMENTS – TRAFFIC STUDY CITY OF FORT COLLINS ROLLINS CONSULT LLC AUGUST 28, 2019 3 Figure 3 – Site Plan Provided by Russell + Mills Studios PROJECT TRIPS AND DISTRIBUTION The trip generation of the proposed project was determined based on rates that were developed by the City of Fort Collins for student housing. The rates and associated trips are provided in Table 1. As shown the project will generate approximately 145 daily, 10 morning and 25 evening peak hour trips. The resulting peak hour trips at the proposed driveway are depicted on Figure 4.

The background traffic for 2021 was based on the following three elements: • The existing traffic at the intersection of Prospect Road and Whitcomb Street was obtained from the City of Fort Collins. The most recent counts were performed during October of 2017. This count data is provided in Appendix A. • The 2017 counts were factored upward by 4 percent to account for overall growth. • Traffic from three nearby projects was added to the base traffic volumes. These projects are: 821 W Lake Street Apartments, The Standard, and 808 West Prospect Road (The Slab/Apex Apartments). Trips associated with these projects was obtained from their respective Traffic Impact Studies. The resulting Background Short Range Traffic (without the Project) are provided on Figure 5. Figure 5 – Background Short Range Traffic HAVEN APARTMENTS – TRAFFIC STUDY CITY OF FORT COLLINS ROLLINS CONSULT LLC AUGUST 28, 2019 6 The Total Short Range traffic projections were developed by adding the project traffic shown earlier on Figure 4 to the Background traffic depicted on Figure 5. The Total Short Range Traffic is shown on Figure 6 (note the volumes are rounded to the nearest 5 vehicles). Figure 6 – Total Short Range Traffic TRAFFIC OPERATIONS AT ACCESS DRIVE The future operations at the access drive were evaluated for the peak hours. Transportation professionals evaluate intersections to determine how they are currently operating and will operate in the future. The methods employed can be found in the Transportation Research Board’s, 6th Edition, 2016 Highway Capacity Manual (HCM). Level of service (LOS) is based on a “graded” system from LOS A, very little to no delays to LOS F which represents excessive delays and congestion. A description of the level of service values is provided in Table 2. The intersection operations thresholds for acceptable level of service are provided in the Larimer County, Urban Area Street Standards (LCUASS), most recently updated September 19, 2016. For an Arterial/Local unsignalized intersection, the overall threshold is LOS D and for an approach leg is LOS F. HAVEN APARTMENTS – TRAFFIC STUDY CITY OF FORT COLLINS ROLLINS CONSULT LLC AUGUST 28, 2019 7 Table 1 - Unsignalized Intersection Level of Service Definitions (HCM Method) Level of Service Average Control Delay Per Vehicle (Seconds) Description A £10.0 No delay for stop-controlled approaches. B 10.0 and £15.0 Operations with minor delay. C >15.0 and £25.0 Operations with moderate delays. D >25.0 and £35.0 Operations with increasingly unacceptable delays. E >35.0 and £50.0 Operations with high delays, and long queues. F >50.0 Operations with extreme congestion, and with very high delays and long queues unacceptable to most drivers. Source: Transportation Research Board, Highway Capacity Manual, 2016. The results of the intersection operations analysis at the proposed Haven Apartments access drive indicate: • During the AM Peak Hour, the LOS for the Southbound right-turn is A with a projected average delay per vehicle of 9.9 seconds. • During the PM Peak Hour, the LOS for the Southbound right-turn is B with a projected average delay per vehicle of 14.3 seconds. • The overall operations are LOS A for both the AM and PM peak hours. The detailed worksheets are provided in Appendix B. PEDESTRIAN ENVIRONMENT/ANALYSIS The City of Fort Collins has established pedestrian and bicycle level of service definitions. They address a number of elements, or quality indicators that impact the environments these users experience. The City’s Pedestrian Plan, February 15, 2011 describes the parameters to evaluate the pedestrian environment. The proposed project is within the “Downtown/CSU Pedestrian District”. Within Pedestrian Districts, the City has established a LOS A for each of the elements listed below with the exception of Street Crossings at a LOS B. The elements identified as important to supporting a beneficial pedestrian environment are: 1. Directness 2. Continuity 3. Street Crossings 4. Visual Interest and Amenity 5. Security Each of these is described in depth in the Pedestrian Plan. The Plan requires that destinations within 1,320 feet of the Project are identified and analyzed for each pedestrian element. This HAVEN APARTMENTS – TRAFFIC STUDY CITY OF FORT COLLINS ROLLINS CONSULT LLC AUGUST 28, 2019 8 area is depicted on Figure 7. The results of this analysis are summarized in Table 3 along with the associated LOS for each element.

The bicycle analysis is for Continuity adjacent to the Project and to these destinations. The results are provided in Table 4. It should be noted that similar to other traffic studies within the area, it was assumed that the improvements along Prospect identified in the West Central Neighborhood Plan, have been built. Table 4 – Bicycle Level of Service Destination Type Continuity LOS Minimum Actual Proposed Colorado State University Institution C A A Future Commercial North of Spring Creek and East of Shields Neighborhood Commercial C B B CONCLUSIONS The proposed Haven Apartments will accommodate a 54 bed multi-family residential project. Vehicular access to the site is limited to a right-in/right-out driveway onto Prospect Road. A key bicycle and pedestrian access are the connection to the existing bike/ped path to Lake Street. The project is anticipated to generate approximately 145 daily, 10 morning and 25 evening peak hour vehicular trips. The project will enhance Prospect Road by being built to accommodate the planned 10-foot bike/ped path. It is not anticipated that this project would result in any significant impacts to the transportation system.
