HomeMy WebLinkAboutTHE GROVE AT FORT COLLINS - PDP - 16-10B - REPORTS - TRAFFIC STUDY (7)of the approach volumes in 2010 are 1942 vehicles in the morning peak hour and 2778
vehicles in the afternoon peak hour. There was a reduction of 74 vehicles and 177 vehicles
in the respective peak hours.
At the Prospect/Centre intersection, the approach volumes are higher on three of the
four legs in the morning peak hour and less on all legs in the afternoon peak hour in 2010
compared to 2009. The sum of the approach volumes in 2009 are 2312 vehicles in the
morning peak hour and 3045 vehicles in the afternoon peak hour. The sum of the
approach volumes in 2010 are 2314 vehicles in the morning peak hour and 2909 vehicles
in the afternoon peak hour. The morning peak hour volume was, virtually, the same (+6)
and there was a reduction of 136 vehicles in the afternoon peak hour.
On the south leg of Centre Avenue, both the northbound and southbound traffic was
lower in both peak hours in 2010 compared to 2009. The total 2009 volume on the south
leg of the Centre Avenue was 968 vehicles in the morning peak hour and 1078 vehicles in
the afternoon peak hour. The total 2010 volume on the south leg of Centre Avenue was
774 vehicles in the morning peak hour and 859 vehicles in the afternoon peak hour. This
results in a reduction of 194 vehicles and 219 vehicles in the respective peak hours. From
this, it is concluded that there is a corresponding reduction in traffic on Centre Avenue
further to the south near Rolland Moore Drive and the other NRRC accesses on Centre
Avenue, which are near the Grove at Fort Collins site.
The cited TIS evaluated the impacts with both higher site generated traffic and
higher background traffic. Given this information, it is respectfully requested that a new TIS
not be required with the proposed change in the Grove at Fort Collins site plan.

SUBJECT: The Grove at Fort Collins Transportation Impact Analysis - Traffic Count
Analyses
(File: 0920ME02)
The Grove at Fort Collins is a proposed student housing development located within
the Centre for Advanced Technology in Fort Collins. A transportation impact study (TIS)
"The Grove at Fort Collins TIS," dated May 2010 was prepared and accepted by the City of
Fort Collins. The cited TIS reflected a population of 624 persons (beds).
Due to various planning issues, a new site plan was developed which addressed
these issues. The proposed population is now 612 persons (beds). The reduction in the
number of beds would have a corresponding reduction in the trip generation for The Grove
at Fort Collins. It is not known whether the new plan would require a new TIS. One reason
to require a new TIS is that the traffic counts in the cited TIS are more than one year old
(Larimer County Urban Area Street Standards, Section 4.4.1.A). In order to aid in making
that determination, Ward Stanford, Fort Collins Traffic Operations, requested a comparison
of the traffic counts in the cited TIS and the most recent traffic counts at the same
signalized intersections. The most recent counts were obtained by the City of Fort Collins
at the prospect/Centre intersection (8/24/10) and the Shields/Rolland Moore intersection
(3/3/10).
Figure 1 shows the 2009 peak hour counts at the subject intersections. Figure 2
shows the 2010 peak hour counts at the subject intersections. A comparison of the
approach volumes would give an indication of how much change in traffic has occurred
between 2009 and 2010. The approach volumes at each intersection are also shown on
Figure 1 and Figure 2.
At the Shields/Rolland Moore intersection, the approach volumes on all legs were
less in 2010 compared to 2009. The sum of the approach volumes in 2009 are 2016
vehicles in the morning peak hour and 2955 vehicles in the afternoon peak hour. The sum
