~ CWCB staff performs technical reviews on the following types of reports and maps for approval and designation by the Board: . . "Flood Insurance Study" (FrS), which is produced by the Federal Emergency Management Agency (FEMA) and used for floodplain management, regulation, and insurance purposes. . "Flood Insurance Rate Map" (FIRM), which is produced by FEMA and used for floodplain management, regulation, and insurance purposes, A FIRM may be published with or without an associated hydrologic and hydraulic report, . "Flood Hazard Boundary Map" (FHBM), which was produced by the Federal Insurance Administration and are used for floodplain management, regulation, and insurance purposes. An FHBM usually depicts approximate floodplain boundaries only, and does not have an accompanying report, Note: For all FHBM designations, the CWCB staff will perform (in-house or by contract with a consultant) hydrologic analyses, . "Floodplain Information Reports", which are produced by local governments, state and federal agencies, special districts, or the private sector, and are used for floodplain management purposes and usually adopted by FEMA for use in Flood Insurance Rate Map revisions. . Various hydrology studies and related floodplain studies (community-wide or site specific) that depict 100-year floodplain information that is useful for floodplain management purposes. .

Floodplain resolution number: FPR 03-568 Affected communities: Unincorporated portions of Fremont County and the City of Florence. Name of study to be formally acted on: "Letter of Map Revision, Oak Creek, Fremont County, Colorado", dated December 2, 2002, by Federal Emergency Management Agency (FEMA). Studied streams: Oak Creek Technical issues: A letter dated December 2, 2002 from FEMA to Fremont County indicates that the effective Flood Insurance Rate Map (FIRM) and Flood Insurance Study (FrS) are being revised to show the effects of improved hydrologic and hydraulic modeling that incorporated more detailed topographic information along Oak Creek from approximately 100 feet upstream of the AT&SF railroad bridge crossing upstream approximately 4,300 feet to the Town of Williamsburg corporate boundary. Additional modeling was performed within the Town of Williamsburg along Oak Creek for an additional 3,000 feet . of stream length up to Quincy Street. The flood hazard d:;tta for Williamsburg on the FIRM and FrS is shown for informational purposes only, As a result of the modifications approved by FEMA, 100-year flood elevations for Oak Creek increased in some areas and decreased in others. The revised map panel will be used for all flood insurance policies and renewals issued within the community. Community response: The CWCB staff has been largely involved with the development of the floodplain information for Oak Creek and has met numerous times with the City of Florence, the Corps of Engineers and FEMA during the development and compktion process of the study, The City and the Corps are in agreement with the results of the study and are very supportive of having the new information become designated and approved by the Board. Staff findings: CWCB staff is confident that all new data developed for Oak Creek is in conformance . with the CWCB' s rules and regulations for floodplain designation and approval. Flood Protection.
