DEFINITIONS CURRENT: Freeboard means a factor of safety, usually expressed in feet above the BFE, which is applied for the purposes of floodplain management. It is used to compensate for the many unknown factors that could contribute to flood heights greater than those calculated for the base flood. CHANGE TO READ: Freeboard means a factor of safety, usually expressed in feet above a flood level, for purposes of floodplain management. Freeboard tends to compensate for the many unknown factors that could contribute to flood heights greater than those calculated for the base blood and floodway conditions, such as wave action, debris lockage of bridge openings and culverts, and the hydrologic and hydraulic effects of urbanization of the watershed. (2) ARTICLE 5. PROVISIONS FOR FLOOD HAZARD REDUCTION SECTION A. GENERAL STANDARDS FOR ALL ZONES (5) CURRENT: Electrical, heating, ventilation plumbing, air conditioning equipment and other service facilities shall be designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding, such facilities shall be located at or above the base flood elevation. CHANGE TO READ: Electrical, heating, ventilation plumbing, air conditioning equipment and other service facilities shall be designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding, such facilities shall be located at or above the base flood elevation plus one (1) foot of freeboard. (3) ARTICLE 5. PROVISIONS FOR FLOOD HAZARD REDUCTION SECTION A. GENERAL STANDARDS FOR ALL ZONES (11) CURRENT: When new construction and substantial improvements are located in multiple flood zones or in a flood zone with multiple base flood elevations, they shall meet the requirement for the more stringent flood zone and the highest base flood elevation. CHANGE TO READ: When new construction and substantial improvements are located in multiple flood zones or in a flood zone with multiple base flood elevations, they shall meet the requirement for the more stringent flood zone and the highest base flood elevation plus one (1) foot of freeboard. (4) ARTICLE 5. PROVISIONS FOR FLOOD HAZARD REDUCTION SECTION A. GENERAL STANDARDS FOR ALL ZONES (13) CURRENT: New construction and substantial improvements built on fill shall be constructed on properly designed and compacted fill that extends beyond the building walls before dropping below the base elevation and shall have appropriate protection from erosion and scour. CHANGE TO READ: New construction and substantial improvements built on fill shall be constructed on properly designed and compacted fill that extends beyond the building walls before dropping below the base elevation plus one (1) foot of freeboard and shall have appropriate protection from erosion and scour. (5) ARTICLE 5. PROVISIONS FOR FLOOD HAZARD REDUCTION SECTION A. GENERAL STANDARDS FOR ALL ZONES (14) CURRENT: None CHANGE TO READ: New construction and substantial improvements shall have the lowest floor elevated to or above the base flood elevation plus one (1) foot of freeboard. (6) ARTICLE 5. PROVISIONS FOR FLOOD HAZARD REDUCTION SECTION B. SPECIFIC STANDARDS FOR RIVERINE ZONES (1) RESIDENTIAL CONSTRUCTION CURRENT: Residential Construction. New construction or substantial improvement of any residential building (or manufactured home) shall have the lowest floor, including basement, elevated to or above the base flood elevation. CHANGE TO READ: Residential Construction. New construction or substantial improvement of any residential building (or manufactured home) shall have the lowest floor, including basement, elevated to at least one (1) foot above the Base Flood Elevation (BFE). (7) ARTICLE 5. PROVISIONS FOR FLOOD HAZARD REDUCTION SECTION B. SPECIFIC STANDARDS FOR RIVERINE ZONES (2) COMMERICAL/INDUSTRIAL CURRENT: Commercial / Industrial. New construction or substantial improvement of any commercial, industrial, or non-residential building (or manufactured home) shall have the lowest floor, including basement, elevated to or above the base flood elevation. Buildings located in all A-Zones may be flood-proofed in lieu of being elevated provided that all areas of the building below the base flood elevation are water tight with walls substantially impermeable to the passage of water, and use structural components having the capability of resisting hydrostatic and hydrodynamic loads and the effect of buoyancy. CHANGE TO READ: Commercial / Industrial. New construction or substantial improvement or any commercial, industrial, or non-residential building shall have the lowest floor, including basement, elevated to at least one (1) foot above the Base Flood Elevation (BFE), or together with attendant utility and sanitary facilities be designed so that below one (1) foot above the Base Flood Elevation (BFE) the structure is watertight with walls substantially impermeable to the passage of water. (8) ARTICLE 5. PROVISIONS FOR FLOOD HAZARD REDUCTION SECTION B. SPECIFIC STANDARDS FOR RIVERINE ZONES (3) ELEVATED BUILDINGS WITH ENCLOSURES BELOW BFE. CURRENT: Elevated Buildings with Enclosures Below BFE. New construction or substantial improvements of elevated buildings that include fully enclosed areas formed by foundation and other exterior walls below the base flood elevations shall be designed to preclude finished living space and designed to allow for the entry and exit of floodwaters to automatically equalize hydrostatic flood forces on exterior walls. CHANGE TO READ: Elevated Buildings with Enclosures Below BFE. New construction or substantial improvements of elevated buildings that include fully enclosed areas formed by foundation and other exterior walls below the base flood elevations shall be designed to preclude finished living space and designed to allow for the entry and exit of floodwaters to automatically equalize hydrostatic flood forces on exterior walls. The lowest floor reference shall be interpreted as at least one (1) foot above the Base Flood Elevation (BFE) where applicable. (9) ARTICLE 5. PROVISIONS FOR FLOOD HAZARD REDUCTION SECTION B. SPECIFIC STANDARDS FOR RIVERINE ZONES (6) Standards for Manufactured Homes and Recreational Vehicles. (a) CURRENT: All manufactured homes to be placed or substantially improved within zoned A1-A30 and AH shall be elevated on a permanent foundation such that the lowest floor of the manufactured home is at or above the base flood elevation and shall be securely anchored to an adequately anchored foundation. CHANGE TO READ: All manufactured homes to be placed or substantially improved within zoned A1-A30 and AH shall be elevated on a permanent foundation such that the lowest floor of the manufactured home is at least one (1) foot above the Base Flood Elevation (BFE) and shall be securely anchored to an adequately anchored foundation.

(a) General Standards (ii) CURRENT: Have its lowest floor elevated no lower than the base flood elevation.
