CERTIFICATION I hereby certify that this report for the final drainage design of City Park North was prepared by me (or under my direct supervision) in accordance with the provisions of the City of Fort Collins Storm Drainage Design Criteria and Construction Standards, for the owners thereof. Kevin Forbes Registered Professional Engineer State of Colorado No. 35265 City Park North is a replat of Frey Street Cottages, situate in the Southwest % of Section 10, Township 7 North, Range 69 West of the 6th P.M., Fort Collns, Larimer County, Colorado. The site gross area is 39,826 square feet. EXISTING SITE The existing site has been built and graded according the Frey Street Cottages construction plans. This property historically received runoff from the West that flows across the South end of our site into Larimer County Canal No. 2. See the offsite exhibit map for sub -basin to this site. It begins at the New Mercer Canal as the West boundary. This offsite area is 10.4 acres. The City uses the Larimer County Canal No. 2 ditch during the 100-year storm from their City Park Lake Project. The 100-year elevation in the ditch will be at 5044.7 feet. This will result in flows from the canal entering our detention pond. This should not be a problem as our flows will be released before the City backwater is to the 5044.7 feet elevation. This concept has been allowed by the city. THE DEVELOPED SITE The developer is proposing four single-family homes, with a common driveway for Lots 3 and 4. A detention pond has been built along with the wild life corridor. The ponds release rate is the two year historic runoff rate. A storm sewer has been be constructed along our South property line to handle the offsite flows to the existing alley on the West side of Frey Street. A double wide no curb inlet has been constructed. Also a no curb inlet was constructed on the East side of Frey in our 20-foot wide driveway to catch the flows from Frey Street from both the North and South. The outlet from the pipe is into the ditch 0.38 feet above the historic high water line mark. The detention pond also includes extended detention for the 40-hour drain time. A water quality structure was installed for the outlet from the pond to the Larimer canal No. 2. The outlet elevation is set at 0.50 feet above the Canal's high water line. EROSION CONTROL AND BEST MANAGEMENT PRACTICES This site is in the City's moderate rainfall erodibility and moderate wind erodibility zone.
