In all areas of special flood hazard the following provisions are required: 1. New Construction and substantial improvements shall be anchored to prevent flotation, collapse or lateral movement of the structure. 2. Manufactured homes shall be anchored to prevent flotation, collapse or lateral movement. Methods of anchoring may include, but are not limited to, use of over- the-top or frame ties to ground anchors. This standard shall be in addition to and consistent with applicable state requirements for resisting wind forces. 3. New construction and substantial improvements shall be constructed with materials and utility equipment resistant to flood damage. 4. New construction or substantial improvements shall be constructed by methods and practices that minimize flood damage. 5. 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. 6. New and replacement water supply systems shall be designed to minimize or eliminate infiltration of flood waters into the systems and discharges from the systems into flood waters. 7. New and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltration of flood waters into the systems and discharges from the systems into flood waters. 8. On-site waste disposal systems shall be located and conducted to avoid impairment to them or contamination from them during flooding. 9. Any alteration, repair, reconstruction or improvements to a building which is in compliance with the provisions of the ordinance, shall meet the requirements of “new construction” as contained in this ordinance. ---PAGE BREAK--- SECTION 20-502. SPECIFIC STANDARDS All areas of special flood hazard where base flood elevation data have been provided, as set forth in Article III, Section 20-302, or Article IV, Section [EMAIL REDACTED], the following provisions are required: 1. Residential Construction. New construction or substantial improvement of any residential building (or manufactured home) shall have the lowest floor, including basement, elevated no lower than the level of the base flood elevation. Should solid foundation perimeter walls be used to elevate a structure, openings sufficient to facilitate the unimpeded movements of flood waters shall be provided in accordance with standards of. Article V, Section 20-502 3. 2. Non-residential Construction. New construction or substantial improvement of any commercial, industrial, or non-residential building (or manufactured home) shall have the lowest floor, including basement, elevated no lower than the level of 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 required 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. A registered professional engineer or architect shall certify that the standards are satisfied. Such certification shall be provided to the official as set forth in Article IV, Section 402 2. 3. Elevated Buildings. New construction or substantial improvements of elevated buildings that include fully enclosed areas formed by foundation and other exterior walls below the base flood elevation shall be designed to preclude finished living space and designed to allow for the entry and exit of flood waters to automatically equalize hydrostatic flood forces to exterior walls. a. Designs for complying with this requirement must either be certified by a professional engineer or architect or meet the following minimum criteria: Provide a minimum of two openings having a total net area of not less than one square inch for every square foot of enclosed area subject to flooding. The bottom of all openings shall be no higher than one foot above grade. Openings may be equipped with screens, louvers, valves or other coverings or devices provided they permit the automatic flow of floodwaters in both directions. b. Access to enclosed area shall be the minimum necessary to allow for parking of vehicles (garage door) or limited storage of maintenance equipment used in connection with the premises (standard exterior door) or entry to living area (stairway or elevator). c. The interior portion of each enclosed area shall not be partitioned or finished into separate rooms.
