4b <br /> subdivision, and other regulations exceed requirements of <br /> the NFIP in that development within floodplains is not <br /> allowed, even if the structure is elevated or floodproofed <br /> in accordance with NFIP requirements. <br /> The Planning Staff was, however, provided with a model <br /> ordinance for use by local jurisdictions, which includes <br /> some changes since the last update to the Flood Damage <br /> Prevention Ordinance in 1991. The text of the model <br /> ordinance is for the most part the same as that found in <br /> the Orange County Flood Damage Prevention Ordinance, <br /> although the County ordinance is organized and numbered <br /> differently. <br /> The changes in the model ordinance which are considered by <br /> FEMA to be substantive in nature include the following: <br /> 1) addition of several new definitions; <br /> 2 ) revision of several definitions related to the <br /> expansion, renovation and improvement of existing <br /> structures or facilities to establish a limit above <br /> which such changes must meet current requirements; and <br /> 3) revision of various technical requirements relating to <br /> elevating and/or flood-proofing existing, or new <br /> structures located within the floodplain. <br /> 4) revision of plot plan requirements. <br /> Because the provisions of the zoning ordinance, <br /> particularly those applicable to watershed protection <br /> overlays, are considerable more restrictive than FEME <br /> requirements, the changes will have little or no impact on <br /> development, but will assure technical consistency with <br /> FEMA regulations. <br /> The Planning Staff recommends that the existing Flood <br /> Damage Prevention Ordinance be replaced with the new model <br /> ordinance in order to assure consistency in content and <br /> format with the National Flood Insurance Program technical <br /> requirements. <br /> (Since the Zoning Ordinance now applies to all of Orange <br /> County's planning jurisdiction, the requirements of the <br /> NFIP could be included in the Zoning Ordinance rather than <br /> in a freestanding Flood Damage Prevention Ordinance. <br /> Inclusion of these provisions in the Zoning Ordinance, <br /> which would allow for the elimination of the FDPO as a <br /> separate Ordinance, will be undertaken in the future <br /> during the process of creating a Unified Development <br /> Ordinance. Replacement of the FDPO rather than <br /> incorporation of its provisions into the Zoning Ordinance <br /> is proposed at this time due to FEMA deadlines for <br /> adoption of amendments, which require that the proposed <br /> amendments be presented for public hearing as soon as <br /> possible.) <br />
