The Flood Insurance Study prepared by FEMA contains detailed and approximate engineering <br />information along with IOO-year floodplain delineations for streams and flooding sources within <br />unincorporated Arapahoe County. <br /> <br />. The 1977 FIS is the earliest version of regulatory floodplain information published by FEMA. This <br />report has been superseded by more current information. The county has experienced a tremendous <br />amount of growth and development since 1977, especially in the western sector. The most current <br />floodplain information available to the County (1995 FIS) is now being utilized by the floodplain <br />administrator for floodplain management and NFIP purposes. <br /> <br />. The 1977 FIS is being proposed for designation and approval at this time. The approximate and <br />detailed floodplain information contained in the FIS was the best available information at the time of <br />the study, and was used for local floodplain management until more current information superseded it. <br />The 1977 study will be appropriately rescinded once the latest regulatory floodplain information for the <br />County has been reviewed and designated. <br /> <br />COMMUNITY RESPONSE: <br />A notification letter was sent by CWCB staff to the local floodplain administrator to inform <br />the County of the proposed Board action. The floodplain administrator was also contacted <br />via telephone to discuss the Flood Insurance Study and the designation process. The <br />floodplain administrator verbally supported the Board's action, and there were no apparent <br />concerns or issues regarding this study. The formal Board action for this study is being taken <br />under Rule 9.D.l, community request. The County will send a written request letter in the <br />near future for inclusion in the project file. <br /> <br />SUMMARY: <br />The staff recommends Board approval of the floodplain resolution for unincorporated Arapahoe <br />County that designates the August 1977 Flood Insurance Study and the accompanying Flood <br />Insurance Rate Maps. The approximate and detailed floodplain information within this report has <br />been superseded by more current studies. However, formal action by the Board will assure that the <br />floodplain information has been appropriately recognized by the state, thereby complying with state <br />statutory requirements. <br /> <br />3 <br />
