Re2ional Detention Pond <br /> <br />Authorization: HB 00-1419 <br />Water Source: nJa <br />1enns of Loan: $1,500,000@ 5.00% for 3D-years <br /> <br />County: Weld - S. of Frederick <br />Project Yield: nJa <br />Project Type: Regional Detention Pond <br /> <br />The communities of Dacono, Frederick, Evanston, and Firestone have consistently <br />experienced flooding problems due to storm runoff from irrigated farmlands and adjacent <br />developments. These communities have suffered many recorded flooding events, dating back <br />10 1957, which caused in excess of $300,000 in flood related damages. With significant <br />population growth occurring within the District, the District cooperated in the development of <br />the 1-25 Corridor Master Drainage Plan. The master drainage plan recommended that the <br />existing detention pond located on the south side of Frederick be enlarged to a regional <br />detention pond, to mitigate future flood damage to the surrounding communities. The <br />regional detention pond would encompass over 60 acres of land and store approximately 146 <br />acre-feet of stormwater during a toO-year event. The design is being completed by the Sears- <br />Brown Group in 2000, with construction tentatively scheduled to commence in the Fall of <br />2001. <br /> <br />12. Larimer County - Dry Creek Multi-Obiective Floo4plain Proiect. <br /> <br />Authorization: SB 96-152, Amended SB 97-8 <br />Water Source: Dry Creek Basin <br />Terms of Loan: $920,000 @4.25% for 3D-years <br /> <br />County: Larimer - N. of Ft. Collins <br />Project Yield: N/A <br />Project Type: Flood Mitigation <br /> <br />Dry Creek is located north of Fort Collins, with a majority of its 75 square miles of <br />drainage basin area located within Larimer County. The uppennost portion of the basin <br />consists of range land and irrigated pastures. The lower portion of the basin within the city <br />limits of Fort Collins consists of commerical, industrial, and residentiai development. Over the <br />years the lower 2/3 of the Dry Creek floodplain corridor has almost been completely <br />eliminated due to development. The loo-year runoff for Dry Creek is 5,022 cfs. The intent <br />of the project is to control floodwaters in the upper basin area by means of detention facilities <br />to reduce the peak discharge from 5022 cfs to 500 cfs above the Weld Canal, utilize a specific <br />reach of the Weld Canal to transport the 500 cis, and construct approximately 1.5 miles of new <br />open channei from the Weld Canal to a designated point along Dry Creek, located downstream <br />of existing development. The proposed improvements would remove over 800 structures out <br />of the Dry Creek regulatory loo-year floodplain. The project is currently in the <br />feasibility/preliminary design phase. Tentatively the project schedule is contingent upOn <br />future loan approval, which is currently pianned to be presented to the Board at the November <br />2001 meeting. <br /> <br />13.
