Mr. Robert Smith =CETI:4;14g Storm Drainage Utility City of Fort Collins
P.O. Box 580
Fort Collins, CO 80522
Dear Bob:
This is concerning the storm drainage at the KCOL studio at 1612
Laporte Avenue, Fort Collins, Colorado. The site is made up of a 100
foot by 155 foot (measured to centerline of Laporte Avenue) tract along
with a 20 foot by 398 foot strip of land that ties their studio to their
radio tower property. For the purpose of this drainage report, we are
considering only the 100 foot by 155 foot tract. The tract is a part
of the original City of Fort Collins drainage basin.
The studio is a non—conforming use in a R.L. zoning. KCOL would
like to build a 620 foot square foot addition on the rear of their
building. The addition would only add 333 square feet of hard surfacing
since there is existing concrete on part of the proposed addition.
The rear half of the lot that is adjacent to the radio station on
the North and faces Layland Court is the only offsite area that drains
across the KCOL property.
The site drains from North to South at about 3.00% grade. The
drainage then flows Easterly in the existing gutter pan along the. North
side of Laporte Avenue.
Since the impervious ground cover would only be increased by 2%,
the additional runoff is very small. The existing site is considered
to be historic since the radio station has been at this site more than
40 years. There is no detention on the existing site nor in the adjacent
neighborhood. We therefore are requesting that no detention be required
and that no changes be required to the drainage facilities.
The calculations of the storm water runoff quantities and a copy
of the site plan are enclosed.
If you have any questions regarding this proposed addition to a
non—conforrp,ing,,fuse, please call.
