In all regulatory flood areas, the following provisions are required:
A. Machinery and equipment servicing a building must either be elevated to or above the regulatory flood elevation, or designed to prevent water from entering or accumulating within the components during a flood. This includes heating, ventilating, and air conditioning equipment, hot water heaters, appliances, elevator lift machinery, and electrical junction and circuit breaker boxes. When located below the regulatory flood elevation, a licensed professional engineer's or architect's certification of the design is required;
B. New and replacement water supply systems shall be designed to minimize or eliminate infiltration of floodwaters into the system;
C. New and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltration of floodwaters into the system and discharges from the system into floodwaters. Sanitary sewer and storm drainage systems for buildings that have openings below the regulatory flood elevation shall be provided with automatic backflow valves or other automatic backflow devices that are installed in each discharge line passing through a building's exterior wall;
D. On site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding;
E. Any utilities and/or equipment within the floodplain must be anchored down. (Ord. 1969, 2011)
