COLLEGE AVE. - PDP - PDP160001 - SUBMITTAL DOCUMENTS - ROUND 1 - TRAFFIC STUDYPage 1 Figure 1 – Site Vicinity October 20, 2015 Mr. Sameer Virani Denver, Colorado RE: Cedar Park Emergency Room Transportation Impact Analysis Ft. Collins, CO Sameer: McDowell Engineering has prepared this traffic memorandum for the proposed Cedar Park Emergency Room. The information provided in this memorandum is intended to address the traffic impacts to the greater roadway network associated with the proposed development. Site Description The Cedar Park Emergency Room (ER) project is located at 4858 S. College Avenue. The site is east of S. College Avenue’s current Frontage Road, between Fairway Lane and Palmer Drive. Figure 1 illustrates the site vicinity. The land is currently vacant. There is an Avis car rental facility to the south and mixed commercial building to the north. Development Access Access to the ER facility is from the N. College Avenue Frontage Road. This is a full movement access. The site will also share the adjacent access to the north via an access easement. The City has plans to remove the Frontage Road in the future and utilize a system of alleys and cross‐access agreements to access the N. College Avenue businesses in this area. The site plan allows for future access via a shared alley along the east side of the property in the future. The current Frontage Road and planned future shared alley access both extend from Fairway Lane to Palmer Drive. These two streets access S. College Avenue (US 287) and the great Ft. Collins’ roadway network. The Fairway Lane and S. College Avenue intersection was recently signalized. Proposed access location is illustrated in Figure 2’s proposed site plan. Employees are anticipated to park in the north parking lot, leaving the south and east parking lots near the emergency drop‐off entry for patients and visitors. Internal circulation is achieved by a parking lot and drive aisle that circles the building on the south, east, and north side of the building. Page 3 Trip Generation The applicant is proposing to construct a 8,000sf building to serve as a stand‐alone emergency room. This is similar to an urgent care facility, but they are open 24 hours a day. The facility will not provide in‐patient care. Cedar Park Emergency Room (ER) is anticipating ten employees during a shift. The proposed stand‐alone ER facility is not a standard land use as defined by ITE. ITE Land Use #630, Clinic, best describes the function of the proposed project. A clinic provides “limited diagnostic and outpatient care, but is unable to provide prolonged in‐house care.” The standard trip generation characteristics compiled by ITE in the Trip Generation, 9th Edition, revised 2012, has been applied to the #630 Clinic land use in order to estimate the average daily, AM peak hour, and PM peak hour vehicle trips. A vehicle trip is defined as a one‐way vehicle movement from a point of origin to a point of destination. ITE provides trip generation rates based upon building size and the number of employees. The ER facility is anticipated to be a destination land use. No passby or internal trip reductions were taken for this land use. Refer to Table 1 for a detailed breakdown of the trip generation calculations for this site.

Therefore, the morning peak hour rate based upon the number of employees was applied. Inbound Outbound Table 1 ‐ Project Trip Generation Stand‐Alone Emergency Room Ft. Collins, Colorado Estimated Project‐Generated Traffic 1 Morning Peak Hour Evening Peak Hour The site is anticipated to generate 252 vehicle trips on a typical weekday. The evening peak hour can expect to see a total of 42 vehicles per hour. Buildout Trip Distribution and Assignment The overall directional distribution of the site‐generated traffic was determined based upon the location of the site within the City of Ft. Collins, the available roadway network and the location of the site relative to other emergency room facilities. As this is an emergency room facility, visibility from the adjacent roadway network is critical and will have an impact on the anticipated distribution of inbound site‐generated traffic. It is anticipated that 90% of the inbound Page 4 Traffic assignment is determined by applying the trip generation (Table 1) to the directional distribution. The resulting site‐generated traffic assignment is anticipated to be 15vph/23vph (inbound/outbound) during the evening peak hour from Fairway Lane. Traffic from Palmer Drive is anticipated to be 2vph/3vph (inbound/outbound) during the evening peak hour. Traffic Data Collection The City of Ft. Collins collected traffic data at the intersection of S. College Avenue (US 287) and Fairway Lane on Wednesday, February 25, 2015. This turning movement count data was used to analyze the amount of impact the proposed site‐generated traffic will have on the existing roadway network. Traffic Impacts to Public Roadways The Cedar Park Emergency Room is anticipated to impact the intersection of S. College Avenue (US 287) and Fairway Lane by 1.4 percent (42vph/2,989vph) of the current Year 2015 traffic volumes. This is considered a nominal impact to the existing roadway network. Sight Distance Sight distance at the proposed site access exceeds the LCUASS requirements for access onto a low‐speed frontage road. Conclusions and Recommendations In summary, the proposed Cedar Park Emergency Room facility is anticipated to be adequately served by the existing roadway network. The site plan accommodates the City’s plan for future access via an eastern alley. Sincerely, McDowell Engineering Kari McDowell Schroeder, PE, PTOE Traffic/Transportation Engineer traffic will enter via Fairway Lane and the Frontage Road. The remaining ten percent of site‐generated traffic is expected to enter via Palmer Drive and the Frontage Road.
