Mr. Glen Schlueter
Storm Drainage Utility
City of Fort Collins
P.O. Box 580
Fort Collins, Colorado 80522
Dear Glen:
This is a revision to the drainage report for the Fort Collins Housing
Authority office and maintenance facility site at 1715 West Mountain Avenue.
The grading, drainage and utility plan was signed and approved in February
1992. At the hearing for the Final P.U.D. plan, the site plan was denied
due to neighborhood opposition, and the Final Plat for the P.U.D. was approved.
The Housing Authority has revised the proposed addition to the building
and is resubmitting the plan for approval. The amount of additional impervious
surface has decreased by 512 square feet from the 1992 plan. The amount of
impervious surface being added to the historic area is 2926 square feet.
The reason the impervious area proposed at this time is less than in 1992
is because part of the building is being constructed where concrete existed.
The enclosed grading, drainage and utility plan has been revised to
delineate the proposed addition. The runoff calculations have also been
revised for the new proposal. The original text of the report is enclosed.
The Housing Authority would like the revisions approved since there is
less runoff with this plan than the 1992 plan. If you have any questions
regarding this site, please call.
Sincerely,
(;� a - 61zL�
Richard A. Rutherford, P. E. & L.S.
President
