§ 20-329. Requirements for all Floodplain Districts.

(a)

Minimum development standards. All new construction and substantial improvements must be:

(1)

Designed (or modified) and adequately anchored to prevent floatation, collapse, or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy.

(2)

Constructed with materials and utility equipment resistant to flood damage.

(3)

Constructed by methods and practices that minimize flood damage.

(4)

Constructed with electrical, heating, ventilation, ductwork, plumbing, and air conditioning equipment and other service facilities that are designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding.

(b)

Flood capacity. Floodplain developments must not adversely affect the hydraulic capacity of the channel and adjoining floodplain of any tributary watercourse or drainage system.

(c)

The storage or processing of materials that are, in time of flooding, flammable, explosive, or potentially injurious to human, animal, or plant life is prohibited.

(d)

Critical facilities are to be located, so that the lowest floor is not less than three feet above the regional flood elevation, or the 500-year flood elevation, whichever is higher.
