RE Grease Monkey and Carwash, , Lot 5, Rigden Farm,, a Filing Stormwater
Compliance
Dear Mr. Schlueter:
Please review the attached documentation for compliance regarding the proposed Grease Monkey &
Carwash development in The Shops at Rigden Farm, Lot 5. The Final Drainage Report For The Shops
at Rigden Farm, Ft. Collins, Colorado, Kimley-Hom and Associates, Inc., Approved March 11th,• 2004,
was used as the guideline for design of this site. The grading and drainage plan submitted is in general
compliance with this report.
The propose site has been graded with slopes'ranging.from 1 - 2-1/2% on average. Two drainage
basins were developed to serve the approximate Northwest and Central/Southeast portions of the site.
The Central/Southeast basin drains to a proposed 4' curb inlet with a 100 yr flow of 1.40 cfs. The
Northwest basin drains to an existing.curb inlet (A-4, Kimley-Horn) with a 100 yr flow from the site of
.70 cfs. The proposed system uses .the existing system installed for The Shops at Rigden Farm.
Proposed non -point offsite flows consisting of grass, sidewalk, and landscaped areas amount to 0.28
cfs. An existing area inlet (A-3, Kimley-Hom) will be removed and the existing drainage will be split
between the proposed curb inlet and the existing inlet A4.
All proposed pipe is Class III, 18" RCP.
Calculations were performed using Urban Drainage guidelines. A copy of Sheets 3 (Grading Plan), 4
(Utility Plan), and 5 (Erosion and Drainage Plan) of the proposed site plan are provided as exhibits for
your convenience.
Sincerely,
Kurt Kowar, P.E.
