<br />. <br /> <br />e <br /> <br />e <br /> <br />e <br /> <br />ATTACHMENT 1 <br /> <br />FPR 99-479 <br />Flood Hazard Boundary Maps, Park County, Colorado (unincorporated <br />areas), dated November 22, 1977 including a new Floodplain Information <br />Report, Park County, Colorado, dated January 1999. <br /> <br />KEY ISSUES: <br />. This resolution was previously tabled at the January 1999 Board meeting pending a meeting with Park <br />County officials. Following the January Board meeting, CWCB staff met with Park County staff and <br />all is well. <br /> <br />· The Flood Hazard Boundary Maps (FHBMs) contain approximate IOO-year floodplain information <br />(Zone A) for certain streams within the county. There are no detailed floodplain delineations for <br />unincorporated Park County at this time. A new Floodplain Information Report was prepared by <br />CWCB staff to provide approximate IOO-year flood hydrology information to accompany the existing <br />floodplain maps. <br /> <br />· A portion of the area on FHBM panel # 9 is now within the corporate limits of the Town of Fairplay. <br />That portion of panel #9 was previously designat~d by the CWCB <br /> <br />· The areas of Park County along the North Fork of the South Platte River below an elevation of <br />approximately 7000 feet (downstream of Bailey) :md along the South Platte River below an elevation of <br />approximately 7000 feet Oust upstream of Cheesman Reservoir) are in a hydrologic region for which <br />the CWCB has developed a hydrology regression equation. The remainder of the South Platte River <br />Basin in Park County is in an area of no regression, and the only available regression equations are <br />preliminary equations developed by the USGS. The southwestern portion of the county are in one <br />hydrologic region of the Arkansas River Basin and the southeastern portion of the county are in another <br />hydrologic region of the Arkansas River Basin (both with CWCB regression equations developed). <br /> <br />COMMUNITY RESPONSE: <br />Park County officials sent a letter to the CWeB requesting designation and approval of the <br />November 22, 1977 maps. A meeting with County officials was held to discuss the <br />designation process and answer floodplain-rehlted questions. A site visit was also performed <br />to investigate streams and floodplain developD1ent in portions of the County. County staff is <br />supportive ofthe Board's proposed designation action. <br /> <br />SUMMARY: <br />The staff recommends Board approval of the floodplain resolution for Park County designating the <br />1977 Flood Hazard Boundary Maps and the accompanying Floodplain Information Report dated <br />January 1999. The approximate floodplain information contained on the FHBMs meets the <br />Board's "Floodplllin Designation and Approval Rules". The designation action will assure that <br />the most current floodplain information for Park County, for the purposes of federal regulation and <br />flood insurance, is explicitly approved by the state, thereby complying with state statutory <br />requirements. <br /> <br />5 <br />
