MEMORANDUM
TO: Rob Beery, Miller Weingarten
Joe Carter, Cityscape Urban Design
Marc Virata, Fort Collins Engineering
FROM: Matt Delich
DATE: May 28, 2003
SUBJECT: Timberline village Transportation Impact Study Addendum
(File: 0221ME03)
There will be two access driveways accessing Milestone Drive.
The west access currently exists and has a curb return design at the
Milestone Drive intersection. The east access is proposed and will
access the "main body" of Timberline Village. Marc Virata has
requested justification for the curb return design for the east
driveway access to Milestone Drive.
The applicable detail for a standard drive approach is depicted
on Drawing 7-07 in the "Larimer County Urban Area Street Standards."
The proposal is that this access would be a Type III Standard
Driveway Approach. According to the "box" on Drawing 7-07, this
access would be categorized as a commercial access and would, by
definition, have a curb return design. It appears that the
designation of whether it is a high volume driveway only applies to
residential land uses. A high volume driveway is defined as having a
volume greater than 350 trip ends per day or a volume greater than 35
trip ends per hour.
However, in the event that the east access must be shown to be
a high volume driveway, I have reviewed the cited transportation
impact study. Figure 8 shows the short range site generated traffic.
The traffic at the Timberline/Milestone intersection must go to/from
one of the two accesses. The work sheets from the traffic assignment
process indicate that the volume on the east access will 120 in the
morning peak hour and 289 in the afternoon peak hour. Both of these
are significantly over 35 trip ends per hour.
It is concluded that this access meets the criteria of a
commercial access and a high volume driveway. It should be designed
as a curb return standard drive approach.
