Re: Markley Honda Renovation Project
Project No. 1159.0001.00
Dear Ms. Langenberger
On behalf of Markley Motors, TST respectfully requests a variance to the criteria
regarding drainage at curb cuts (Larimer County Urban Area Street Standards,
Chapter 9, section 9.4.11.A). Per that section, it indicates that "concentrated storm
water runoff from property adjoining the right-of-way shall not be discharged across
the sidewalk."
As has been previously discussed and determined, per the preference of the City
Planner and City Forester, no sidewalk is being built on the north side of Monroe
Drive. An installation of sidewalk on this side of the road would have directly
impacted, and possible caused the loss of, several mature trees. Therefore,
because there will be no sidewalk, there will not be a need to direct the flows
elsewhere to avoid discharging across the sidewalk. In addition, the driveway being
constructed is a high volume driveway which will have curb returns and a crosspan
similar to an intersection. This will direct the flows along the curb and gutter instead
of sheet flow across the entire entrance.
This variance is not anticipated to impact construction or maintenance costs, and
may decrease costs. By allowing the drainage to be released via the drive entrance,
it will eliminate two onsite curb chases and a third curb chase that would have tied
into the curb along Monroe west of the new entrance.
There is no perceived or anticipated risk to the health and safety of the public due to
this variance from the design criteria given that the sidewalk along Monroe is on the
south side and will not be impacted by this new drive access.
Thank you for your consideration of this variance request. Please feel free to contact
me with any questions or to discuss this request further.
Sincerely,
TST, INC. CONSULTING ENGINEERS
