Construction of new critical facilities shall be located outside the limits of the floodplain. If no feasible alternative, lowest floor elevated to BFE + 1 foot. Access routes elevated to BFE.

In zones A, AE, AH, AO, and A1-A30, fully enclosed areas, of new construction or substantially improved structures, which are below the regulatory flood protection elevation shall: Not be designed or used for human habitation, but shall be used solely for parking of vehicles, building access, or limited storage of maintenance equipment...

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.

All subdivision proposals shall be consistent with the need to minimize flood damage; shall have public utilities and facilities located to minimize flood damage; shall have adequate drainage; and where BFE data not available, it shall be generated for proposals with at least 50 lots or 5 acres.

Electrical, heating, ventilation, plumbing, air conditioning equipment, and other service facilities, including duct work, shall be designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding.

On-site waste disposal systems shall be located and constructed to avoid impairment to them or contamination from them during flooding.

New and replacement water supply systems shall be designed to minimize or eliminate infiltration of flood waters into the system.

Prior to any proposed alteration or relocation of any channels or of any watercourse, stream, etc., within this jurisdiction a permit shall be obtained from the U. S. Corps of Engineers, the Virginia Department of Environmental Quality, and the Virginia Marine Resources Commission.

The floodplain districts shall be overlays to the existing underlying districts. Any conflict between the provisions or requirements of the floodplain districts and those of any underlying district, the more restrictive provisions and/or those pertaining to the floodplain districts shall apply.
