SCALE: 1 "=500'
SITE LOCATION Figure 1
Currently, this area is served by Transfort Route 1, 2, 3, 4, 6,
7, 11, and 15. It is expected that transit level of service will be
acceptable.
It is concluded that, with development of the SAE House
Redevelopment, the future level of service at the key intersections
will be acceptable. The recommended geometry is shown in Figure 9.
The level of service for pedestrian, bicycle, and transit modes will
be acceptable.
Figure 4 shows the site plan for the SAE House Redevelopment.
The SAE House Redevelopment will consist of 113 apartment beds, a
bagel shop, and a coffee shop. Access to the site will be via the
alley along Laurel Street. Trip Generation, 7=" Edition, ITE was used
as the reference document in calculating the trip generation. This
site being close to the Colorado State University campus, a reduction
(250) was taken for the apartment trips that are expected to walk or
bike to and from this site. Since there is no parking provided for the
Coffee and Bagel shops, a 100 percent discount was taken. Table 2 shows
the trip generation for the SAE House Redevelopment. This trip
generation was discussed and agreed to in the scoping meeting.
The trip distribution for this site is shown in Figure 5. The
trip distribution was determined using the existing traffic counts,
knowledge of the existing and planned street system, development
trends, and engineering judgment. Figure 6 shows the site generated
traffic assignment of the SAE House Redevelopment.
Figure 7 shows the short range (2013) background peak hour
traffic at the key intersections. Background traffic volume forecasts
for the short range (2013) future were obtained by reviewing traffic
studies for other developments in this area and reviewing historic
counts in the area. Table 3 shows the short range (2013) background
peak hour operation at the key intersections. Calculation forms are
provided in Appendix D. The key intersections will operate acceptably
with the existing control and geometry.
Figure 8 shows the short range (2013) total peak hour traffic at
the key intersections. Table 4 shows the short range (2013) total
peak hour operation at the key intersections. Calculation forms are
provided in Appendix E. The key intersections will operate acceptably
during the peak hours. Figure 9 shows the short range (2013) geometry
at the key intersections. This is the existing geometry.
The SAE House Redevelopment site is in an area within which the
City requires pedestrian and bicycle level of service evaluations.
Appendix F shows a map of the area that is within 1320 feet of the SAE
House Redevelopment. The SAE House Redevelopment site is located
within an area termed as "pedestrian district," which sets the level
of service threshold at LOS A for all measured categories except
street crossing, which is B. There are four destination areas within
1320 feet of the proposed SAE House Redevelopment: 1) the Colorado
State University Campus area to the south of the site, 2) the
residential neighborhood to the west of the site, 3) the residential
neighborhood to the north of the site, and 4) the residential
neighborhood/commercial center to the east. Currently there are
sidewalks adjacent to the site along Laurel Street and Howes Street.
Appendix F contains a Pedestrian LOS Worksheet.
Based upon Fort Collins bicycle LOS criteria, the only bicycle
destination is Colorado State University Campus. This site connects
directly to bike lanes on Howes Street, which achieves level of
service B.

MEMORANDUM
TO: Dale Young, Brinkman Partners
Ian Shuff, Aller-Lingle Architects
City of Fort Collins
FROM: Joe/Matt Delich
DATE: June 17, 2008
SUBJECT: SAE House Redevelopment Transportation Impact Study
(File: 0798ME01)
This memorandum addresses the transportation impacts of the
proposed SAE House Redevelopment. The SAE House Redevelopment is
located in the northwest quadrant of the Laurel/Howes intersection, in
Fort Collins. The site location is shown in Figure 1. The SAE House
is currently vacant. The SAE House Redevelopment will consist of 113
apartment beds, a bagel shop, and a coffee shop. The scope of this
study was discussed with the Fort Collins Traffic Operations Engineer.
A brief memorandum was requested. The. Base Assumptions form is
provided in Appendix A. There are sidewalks along developed parcels
of land within 0.25 miles of the site. There are bicycle lanes along
Howes Street and Mason Street.
Figure 2 shows recent peak hour counts at the Laurel/Howes and
Laurel/Alley intersections. The count data at the Laurel/Howes
intersection was obtained in May 2008, by the City of Fort Collins.
The count data at the Laurel/Alley intersection was obtained in June
2008. Raw traffic data is provided in Appendix B. Since the traffic
count at the Laurel/Alley intersection was obtained when Colorado
State University was not in session, the traffic at the Laurel/Alley
intersection was adjusted. This is shown in Figure 3. Table 1 shows
the current peak hour operation of the Laurel/Howes and Laurel/Alley
intersections. Calculation forms are provided in Appendix C. A
description of level of service for signalized and unsignalized
intersections from the 2000 Highway Capacity Manual and a table showing
the Fort Collins Motor Vehicle LOS Standards (Intersections) are also
provided in Appendix C. The key intersections operate acceptably during
the peak hours. The SAE House Redevelopment site is in an area termed
"mixed use district." In areas termed "mixed use district,"
acceptable overall operation at signalized intersections during the
peak hours is defined as level of service E or better. Any leg or
movement can also operate at level of service E or better. At
unsignalized intersections during the peak hours, acceptable operation
is defined as level of service F, which is considered to be normal in
an urban environment.
