study
(File: 9481MEM1)
z
I have reviewed the site plans for The Overlook and The
Gates at Woodridge . I have compared them with the site plans
M used in the "Arapahoe Farm Site Access Study" , March 1991 .
The street layout is basically the same and the number of
units is only 4 higher than that used for this same area in
the cited site access study.
In the site access study, the date of full buildout of
this development was projected to be 1998 . Based upon the
current building activity in the south portion of this
development and this request for final P.U.D. approval , it
would appear that build out will occur by 1996.
Due to the accelerated schedule of this project and other
activity in this part of Fort Collins, traffic volumes are
higher than anticipated at this point in time. This has been
anticipated. The city has requested design of the Taft
Hill/New Harmony/CR38E intersection. I have been involved in
that design activity supplying traffic forecasts and geometry
at this new intersection. Appendix A contains two memoranda
,Z that discuss short range and long range forecasts, geometry,
L and intersection operation.
The trip generation reflected in the site access study
v o is valid for this submittal . In my judgment the site access
a study, coupled with the information contained in Appendix A,
W address the traffic impacts associated with the continuing
® a development in this quarter section.

This memorandum documents my analyses and recommendations
a pertaining to the Taft Hill/CR38E/Harmony intersection.
✓• .
Peak hour traffic counts were obtained at the Taft
Hill/CR38E and Taft Hill/Harmony intersections in 1993 . This
existing traffic was reassigned, since the new intersection
will provide a more efficient route for a significant number
of southbound left turns and westbound right turns at the
existing Taft Hill/Harmony intersection. This background
traffic was factored to reflect a 1998 short range future
year. A traffic assignment for Arapahoe Farm was performed
and added to the 1998 traffic projection. The 1998 peak hour
traffic projection is shown in Figure 1 .
This intersection was evaluated using the signalized.
intersection technique from the 1985 Highway Capacity Manual .
Using a 70 second cycle, the intersection will operate at
level of service B during the analyzed peak hours . The
geometry necessary to achieve this operation is shown in
Figure 2 .
W I did not conduct any long range analysis as of yet.
Daily traffic projections from Eric Bracke (City of Fort
w Collins) indicate that Harmony Road may not proceed on the
w CR38E alignment west of Taft Hill Road. Rather than spend a
lot of time making peak hour projections for a road
. • configuration that may not exist, I thought it best to discuss
_ o this issue in our May 19 meeting with City staff.

This memorandum documents my analyses and recommendations
pertaining to the Taft Hill/CR38E/Harmony intersection using
} long range traffic forecasts .
z
Eric Bracke provided long range (year 2015) traffic
projections from the North Front Range Transportation and Air
A Quality Planning Council Regional TransportationPlan. Using
these and traffic studies for various development projects in
this area, I developed the peak hour projections shown in
Figure 1 .
This intersection was evaluated using the signalized
intersection technique from the 1985 Highway Capacity Manual .
Using an 80 second cycle, the intersection will operate at
Levels of service B and C during the analyzed peak hours . The
geometry necessary to achieve this operation is shown in
Figure 2 .
I would suggest that these volumes and geometry be
z forwarded to city staff for their review and comment. It may
be appropriate that this be done at a meeting so that
discussions can take place .
