Ordinance No. Page 6 of 7 3. All new construction and substantial improvements shall be constructed with electrical, meGhan Gal, heating, ventilation, ung-arvd-air_-conditioning. plumbing, duct systems, and other equipment and other service facilities shall be elevated at or above one )_foot above the base flood elevation, with the exception of: electrical systems, equipment and components: heating, ventilating, air conditioning; plumbing appliances and plumbing fixtures: duct systems; and other service equipment that are designed and/or- installed Ieseted-se--es-to prevent water from entering or accumulating within the components and to resist hydrostatic and hydrodynamic loads and stresses, including the effects of bUo anc . during cond+tieR-s-the occurrence of flooding to the design flood elevation. 4. Require within Zones AH or AO adequate drainage paths around structures on slopes to guide floodwaters around and away from proposed structures. C. Elevation and Floodproofing. 1. New construction and substantial improvement of any structure shall have the lowest floor, including basement, elevated to or above one (afoot higher than the base flood elevation. Nonresidential structures may meet the standards in subsection (C)(3) of this section. Upon completion of the structure, the elevation of the lowest floor, including basement, shall be certified by a registered professional engineer or surveyor, or verified by the community building inspector to be properly elevated. Such certification or verification shall be provided to the floodplain administrator. Nonresidential structures may meet the standards in subsection (C)(3) of this section. Upon the completion of the structure, the elevation of the lowest floor, including basement, shall be certified by a registered professional engineer or surveyor, or verified by the community building inspector to be properly elevated. Such certification or verification shall be provided to the floodplain administrator. 2. New construction and substantial improvement of any structure in Zone AO of AH shall have the lowest floor, including basement, elevated one Lafoot above the depth numberspecified on the FIRM or the highest adjacent grade -at st-as-1,,4h-as-theAepth Rumber specified OR the FIRM, or at least three feet if no depth number is specified. Nonresidential structures may meet the standards in subsection (C)(3) of this section. Upon completion of the forms for the structure's foundation, and prior to pouring the foundation, the elevation of the lowest floor, includinq basement shall be certified by a registered civil engineer or licensed land surveyor, and verified by the building division to be properly elevated. Such certification and verification shall be provided to the flood lain administrator, Upon the completion of the structure, the elevation of the lowest floor, including basement, shall be certified by a registered professional engineer or surveyor, or verified by the community building inspector to be properly elevated. Such certification or verification shall be provided to the floodplain administrator. 3. Nonresidential new construction or substantial improvements shall either be elevated in conformance with subsection (C)(1) or (C)(2) or together with attendant utility and sanitary facilities: a. Be floodproofed so that below one Lhfoot above the base flood level --elevation the structure is watertight with walls substantially impermeable to the passage of water; b. Have structural components capable of resisting hydrostatic and hydrodynamic loads and effects of buoyancy; and C. Be certified by a registered professional engineer or architect that the standards of this subsection are satisfied. Such certifications shall be provided to the floodplain administrator. 4. Require, for all new construction and substantial improvements, that fully enclosed areas below the lowest floor that are subject to flooding shall be designed to automatically equalize hydrostatic flood forces on exterior walls by allowing for the entry and exit of floodwaters. Designs for meeting this requirement must either be certified by a registered professional engineer or architect or meet or exceed the following minimum criteria:
