(A) Where special flood hazard areas have not been defined within the community or a base flood elevation has not been provided, all plans and permits for proposed construction of subdivisions, placement of manufactured homes, or other development shall be consistent with the need to ensure that building sites will be reasonably safe from flooding (44 CFR Part 65.2 defines “reasonably safe from flooding” as base flood waters will not inundate the land or damage structures...and that any subsurface waters related to the base flood will not damage existing or proposed buildings). The test of reasonableness is a local judgment and includes historical data, high water marks, photographs of past flooding, and the like.
(B) Building lots shall have adequate buildable area outside of regulatory floodways.
(C) Where base flood elevation has not been provided, it shall be generated for subdivision proposals and other proposed developments (including proposals for manufactured home parks and subdivisions) greater than 50 lots or five acres (whichever is the lesser).
(D) Site improvements, subdivisions, and manufactured home parks shall have public utilities and facilities such as sewer, gas, electric, and water systems located and constructed to minimize or eliminate flood damage and infiltration of flood waters into the systems. Replacement public utilities and facilities such as sewer, gas, electric, and water systems, shall likewise be sited and designed to minimize or eliminate damage and infiltration of flood waters.
(E) New and replacement water supply systems shall be designed to minimize or eliminate infiltration of flood waters into the systems. New and replacement sanitary sewerage systems shall be designed to minimize or eliminate infiltration of flood waters in the systems and discharges from the systems into flood waters. Onsite waste disposal systems shall be located to avoid functional impairment to them or contamination from them during flooding.
(F) Subdivision proposals and other proposed new development, including manufactured home parks, shall have adequate drainage provided to reduce exposure to flood hazards as provided in 44 CFR Part 60.3(a)(4). In AO and AH Zones, drainage paths shall be provided to guide flood water around and away from proposed structures.
