Traffic Impact Study Addendum
May 3, 1990
TRANSPLAN Associates, Inc. prepared the PROSPECT EAST BUSINESS PARK Traffic
Impact Study in May, 1984. With the development of an office and warehousing complex within
the Prospect East Business Park, the City of Fort Collins has requested a review of the traffic
impact study.
1. Proiect Data:
An office and warehousing complex within the Prospect East Business Park is proposed.
The project is located in the block bounded by East Prospect Road, Prospect Parkway, Mid Point
Drive, and Specht Point Road. See Figure #1. The building area is 89.600 sq. ft. (Site Plan, City
Scape, 4/10/90).
2: Traffic Data:
Based on the report Trip Generation (Institute of Transportation Engineers, 4th Edition,
1987), the fully occupied development is expected to generate about 1,100 trips on an average
weekday as documented in the following Table 01.

The trip distribution has been reviewed by Mr. Ensdorff, City Traffic Engineer, and is shown in
Figure #2, with the development trip assignment. Evidently, once Timberline Road is extended
north (construction projected for 1.997), the trip distribution will change. Figure #1 shows the
1989 annual average daily traffic volumes in the vicinity of the proposed development, as
obtained from the City of Fort Collins, Transportation Division.
A manual traffic count was taken at the intersection of East Prospect Road and Prospect
Parkway on Wednesday, May 2, 1990 during the evening peak hour. The north -south traffic is
controlled by STOP signs. The levels of service were calculated for the existing traffic and for
the existing traffic plus the development traffic, using the Highway Capacity software. See
Appendix. The analysis assumes two northbound and two southbound lanes, as the drivers use
the street in this manner, even though the street isnot striped,
3. Proiect. Traffic Analvsis:
Overall, the street system can handle the projected development. The critical intersection
of East Prospect Avenue and Prospect Parkway will operate at Levels of Service E/F for
northbound and southbound traffic during the evening peak hour. The traffic signal warrants are
presently not met, and delays will be experienced by the northbound and southbound drivers
during the peak hours. Some drivers from the development will travel to Mid Point Drive and
make a right turn on Timberline Road. This intersection needs to be monitored. As indicated
in the 1984 Traffic Impact. Study, a traffic signal will be warranted at Phis intersection in the
future.
