Bracke, P.E., P.T.O.E DATE: 17 February 2017 SUBJECT: Fossil Creek Apartments – Memorandum TIS This memorandum Transportation Impact Study represents a brief analysis of the Fossil Creek Apartment currently being proposed. The project is located on the west side of College Avenue (US287) between Crestridge Road and Fossil Creek Boulevard in Fort Collins, Colorado. The site has sat vacant for years and numerous proposals have been submitted for this site. The site should be considered an infill development since it is surrounded by older county developments. The project is proposing to take access off of US 287 through a right-in/right out access which is in conformance with the South College Access Control Plan. A roadway will be constructed southward to make a connection to a full movement intersections with US 287 at Crestridge and Skyway. A Full TIS was done on the property in February 2016 for the Vinyard-Goldelm development which included apartments, retail, and a church. A Vicinity Map for the project is displayed below.

The Fossil Creek Apartment project is proposing 214 apartment units. Figures 2 and 3, as shown below show the similarities in the two different proposals. Figure 2 - Vineyard-Goldem Project of February 2016 Figure 3- Fossil Creek Apartment Project – February 2017 ELB Engineering, LLC Fossil Creek Apartments - Memorandum 5401Taylor Lane Transportation Impact Memorandum Fort Collins, CO 80528 970- 988- 7551 ELBEngineering@lpbroadband.net Page | 3 Trip generation between the two proposals was calculated and shown below in Table 1. Based on the calculations, there is very little difference between the original and the current development proposals. The Fossil Creek Apartment project will generate approximately 239 fewer daily trips, 19 fewer AM trips, and 24 fewer PM trips. From a transportation engineering perspective, this difference is negligible.

The conclusions of the original TIS still remain valid and shall be repeated here. College Avenue is a State Highway under the “NRA” classification category with a speed limit of 55 mph. Based on the State Highway Access Code, the following improvements would be required: • Connection of Venus at College Ave.: o Southbound deceleration lane of 600’. This may be difficult to accomplish with the bridge in place over Fossil Creek o A southbound acceleration lane from Venus at a length of 960’ o Some form of median control to prevent the NB left turn and the and the EB left turn from the intersection • The realignment of Crestridge and Smokey should occur with the first phase of the project when signal warrants are satisfied. o A new traffic signal will be warranted at Crestridge/College and is in conformance with the Access Control Plan. o The project will be required to provide auxiliary lanes in conformance with the State Highway Access Code as discussed in the report. o Multi-modal level of service can be satisfied for bikes and transit. LOS for pedestrians cannot be satisfied since there are no sidewalks in the ELB Engineering, LLC Fossil Creek Apartments - Memorandum 5401Taylor Lane Transportation Impact Memorandum Fort Collins, CO 80528 970- 988- 7551 ELBEngineering@lpbroadband.net Page | 4 immediate area. The project will construct the sidewalk system in conformance with the City Standards. Statement of Adequacy: The transportation facilities will be adequate and available to serve this development as contained in the Larimer County Urban Area Street Standards. All applicable LOS standards will be met since all transportation facilities are in place or will be in place upon issuance of a certificate of occupancy.
