ably utilize any base flood elevation and floodway data available from a Federal, State, or other source, as criteria for requiring that new construction, substantial improvements, or other develop- ment in Zone A comply with the standards for flood protection set forth in this ordinance, however, in no case shall such develop- ment within Zone A be less than eighteen (18) inches above the crown of the road or elevation required by the Indian River County Health Department, SECTION 7 B. Stormwater Management and Flood Protection Permit (Type B). When a development project is determined to be within a Flood Hazard Zone according to the procedure set forth in Section 7 A (19) (a -f), a Type B Permit shall be required and the project shall be reviewed under the criteria of Section 7 (A) and must meet the following additional criteria, (1) Except for those development projects within the 100 -year flood.plain along the Indian River, an equal volume of storage capacity must be created for any volume of the regulatory flood that would be displaced by fill or structures. For those development projects within the 100 -year flood plain of the Indian River, an equal volume of storage capacity must be created for any volume of the regulatory flood that would be displaced by fill or structures below elevation 4.0 ft. NGVD or the 10 -year Flood elevation which has been determined by FEMA, whichever is greater. Provided, however, that the Board of County Commissioners may, in its discretion, grant a waiver from the provisions of this subsection upon the affirmative showing of the applicant, by means of a competent engineering study, that the development project is situated in an estuarine environment and that the development project, as designed, will meet all other requirements of the Stormwater Management and Flood Protection Ordinance and will not create a material adverse impact on flood protection on other lands in the estuarine environment. (2) The velocity of the regulatory flood must not be adversely altered on any watercourse. (3) All structures, including buried storage tanks, must be anchored as necessary to resist flotation, lateral forces and the impact of floating debris. (4) No development will be allowed that poses a significant threat of releasing harmful quantities of pollutants to surface waters or groundwaters during flooding. (5) The Flood Protection Elevation shall be set for each project at the elevation of the regulatory flood. �X0$/6fA//f6kVE/. In Coastal High Hazard Zones, the Flood Protection Elevation shall be established with consideration given to wind -drive wave action. All construction within the Indian River County Coastal Zone shall be in compliance with the County's current Coastal Construction Code.
