Dear Eric:
This letter is a variance request for the spacing between a
driveway to/from a gas/convenience store and Timberline Road, along
Sykes Drive, within the East Ridge development. A site plan is
provided in Appendix A. Sykes Drive is considered to be a minor
'collector Street. According to Table' 7-3 in the Larimer County Urban
Area Street Standards, the distance between a high volume driveway and
a street intersection is 175 feet, on -centers. The distance shown is
164 feet.
As shown on the site plan, Sykes Drive will have a raised median
from Timberline Road to Vicot Way. This median will prevent left -ins
and left -outs at the subject driveway. The primary issue related to
the driveway location is that a number of right -turning egressing
vehicles from the subject driveway will desire to get into the
westbound left -turn lane approaching Timberline Road. If there are
more than two vehicles in the left -turn lane, a vehicle exiting the
subject driveway will not be able to get to the back of the left -turn
queue. Analyses in the "East Ridge Transportation Impact Study"
indicate that the left -turn queue will be. approximately five vehicles
during the peak hours. This would indicate that exiting vehicles from
the subject driveway could not get into the left -turn lane during the
peak hours. However, experience would indicate that there would be
periods of time, during the peak hours, when there would be less than
two vehicles in the left -turn lane, especially when/if this
intersection is signalized and the traffic on Sykes Drive clears. At
times when the left -turn queue extends beyond the driveway, it is
likely that the right -turn lane queue would also extend beyond the
driveway. At these times, vehicles exiting the subject driveway could
not get on Sykes. Drive. The delays to the exiting vehicles would be
within the gas/convenience store property and would not negatively
impact the operation of Sykes Drive. Exiting vehicles also have the
alternative of using Vicot Way, which is over 220 feet from the stop
bar on Sykes Drive. Based upon the operational analyses, the queue on
Sykes Drive will not extend to Vicot Way. With this alternative
route, these vehicles can enter either westbound lane on Sykes Drive.
It is recommended that a sign be posted at the subject driveway
stating that "exiting vehicles should not block Sykes Drive." Since
this land use will primarily serve East Ridge and the nearby area,
