(a) Such proposals shall be consistent with the need to minimize flood damage: (b) Such shall have public utilities and facilities such as sewer. gas. electrical. and water systems located and constructed to minimize or eliminate flood damage: and (c) hazards. Such proposals shall have adequate drainage provided to reduce exposure to flood (13) When proposed new construction and substantial improvements are partially located in an area of special flood hazard. the entire structure shall meet the standards for new construction. (14) When proposed new construction and substantial improvements are located in multiple flood hazard risk zones or in a flood hazard risk zone with multiple base flood elevations. the entire structure shall meet the standards for the most hazardous flood hazard risk zone and the highest base flood elevation. Section B. SPECIFIC STANDARDS. In all areas of special flood hazard where base flood elevation data haye been provided, as set forth in ..^~rticle 3, Section B, or Article 1, Section C (11), the following provisions are required: In all A-Zones where base flood elevation data have been provided (Zones AE. Al-30. A (with base flood elevation). and AH). as set forth in Article 3. Section B. the following provisions. in addition to those set forth in Article 5.

New construction or substantial improvement of any residential structure (or manufactured home) shall have the lowest floor, including basement elevated no lower than the base flood elevation. Should solid foundation perimeter walls be used to elevate a structure, openings sufficient to facilitate the automatic equalization of flood hydrostatic forces on both sides of the exterior walls shall be provided in accordance with the standards of Article 5, Section B (3). (2) Non-Residential Construction. New construction or substantial improvement of any commercial, industrial, or non-residential structure (or manufactured home) shall have the lowest floor, including basement, elevated no lower than the base flood elevation. Structures located in A-zones, together with attendant utility and sanitary facilities, may be flood- proofed in lieu of elevation provided that all areas of the structure below the base flood elevation are designed to be water tight, with walls substantially impermeable to the passage of water and structural components having the capability of resisting hydrostatic and hydrodynamic loads and the effect of buoyancy. A registered professional engineer or architect shall certify that the design and methods of construction are in accordance with the FEMA Floodproofing Certificate. Such certification along with the corresponding Flood Damage Prevention Ord. LegislationlOrdinancesl Attorney 7/10/09--11:05 AM 20
