• (2) Requirements of the regular phase of the NFIP which <br /> require that communities must adopt zoning regulations for <br /> their floodplains . Towns and cities in Colorado cannot adopt <br /> such regulations unless and until the Board has designated and <br /> approved delineation of the communities ' floodplains . <br /> (3) The Federal Emergency Management Agency (FEMA) has <br /> established September 30, 1987, as the date by which <br /> communities nationwide must be converted from "emergency phase" <br /> to the " regular phase" of the NFIP. <br /> (4) Because so many communities do not have detailed <br /> delineations of floodplains completed, FEMA intends to provide <br /> only enough funding for some communities to perform approximate <br /> floodplain studies. <br /> (5) If the Board does not designate and approve the <br /> approximate floodplains which will be identified by FEMA' s <br /> forthcoming studies, then Colorado ' s communities will not be <br /> able to enact the zoning regulations which are a prerequisite <br /> to their conversion into the "regular phase" of the NFIP and <br /> the benefits of the NFIP would become unavailable to many <br /> Colorado communities . <br /> Following considerable discussion by Board members of <br /> federal requirements and what other alternatives the Board has, <br /> • Mr . Robbins moved, seconded by Mr . Covert, that the Board adopt <br /> the policy that will henceforth designate and approve <br /> approximate 100-year floodplains subject to the following <br /> conditions: <br /> 1. All approximate floodplain studies shall be performed by a <br /> qualified hydrologist, hydraulic engineer, or registered <br /> professional engineer or firm. <br /> 2 . All information which is presented to the CWCB for <br /> designation shall be entitled, dated, and bound in an <br /> individual document by community or communities . <br /> 3 . As a minimum standard for approximate floodplain studies, <br /> the 100-year discharge shall be computed for all stream reaches <br /> for which the flood hazard area or zone is to be delineated. <br /> 4 . The stream hydrology shall be computed by a CWCB approved <br /> method and shall be comparable in accuracy to the computation <br /> of stream hydrology for a detailed floodplain engineering <br /> study. <br /> 5 . All designations and approvals of approximate 100-year <br /> floodplains by the CWCB will specify that the town/city or <br /> county may not exercise its zoning powers based on the CWCB ' s <br /> designation unless it includes in its zoning ordinances or <br /> • <br /> -7- <br />
