That resolution specifically noted the error in the Dry Creek floodplain delineation and <br />did not designate that portion of the 1996 FIS or rescind Resolutions Nos. 203 or 272. <br /> <br />· Both the CWCB and Larimer County notified FEMA about the drafting error, and FEMA <br />initiated the correction, which resulted in the 1997 FIS. <br /> <br />COMMUNITY RESPONSE: <br />Larimer County sent a letter requesting CWCB designation and approval of the 1997 FIS. <br />CWCB staff discussed the designation with the County' s Floodplain Administrator by <br />telephone conversation and at a meeting with CWCB staff. The County is supportive of the <br />Board's proposed designation and approval ofthe 1997 FIS. <br /> <br />SUMMARY: <br />The staff recommends Board approval of the floodplain resolution for Larimer County. The <br />floodplain information contained in the 1997 FIS corrects a drafting error, allowing the FrS to meet <br />the Board's "Floodplain Designation and Approval Rules". The resolution will assure that the <br />county's most current floodplain information complies with state statutory requirements. <br /> <br />5 <br />
