Box 580 Fort Collins, CO 80522-0580 RE: Raw Water Supply Dear Mr. Barber. CIVIL RES-DURCES,LLC ENGINEERS & PLANNERS STORMWATER RECEIVED AUG 0 4 2003 12x?- Mr. Tom Anderson asked Civil Resources, LLC to address the concerns of Faith Property Management in regards to a widened driveway area that Mr. Anderson constructed and the effect that this additional impervious area may have on the site drainage of Huntington Hills subdivision. Mr. Anderson's home is located on Lot 14 in Huntington Hills, Filing 6 or more commonly known as 5858 Huntington Hills Drive in the City of Fort Collins. The new pavement has a total area of approximately 450 square feet. Approximately 200 square feet of the total area drains to the back of Mr. Anderson's lot and the remaining 250 square feet drains to the front (i.e. to the street). The drainage patterns after construction are consistent with the drainage patterns before the additional area was paved. Attached are two site plats depicting approximate drainage patterns and major features before and after construction of the new pavement, respectively. The soil on Mr. Anderson's lot is a clayey material and therefore has a relatively high runoff coefficient associated with it in its natural condition. Mr. Anderson constructed a small down spout detention area in his front landscaping that will provide approximately 11 cubic feet of detention volume that will help to offset any additional runoff volume generated from the newly paved area draining to the front (street). Please call me if you need any additional information or if you have any questions. Sincerely, CIVIL RESOURCES, LLC. Encls: 1, 451 OAK STREET, SUITE 209 • P.O.
