Memorandum
TO: David Lash AIS
PWN Architects and Planners
FROM: Eric L. 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 Vineyard-Goldem development had proposed 250 apartments (non-student) on the site
in the same general area of the Fossil Creek Apartment Project. 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.

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.

It is concluded that the proposed Fossil Creek Apartment Project is in conformance with
the original TIS that was submitted with the Vineyard-Goldem Project. 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

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.
