Section D.1

In the floodway fringe district, the development and/or use of land shall be permitted in accordance with the regulations of the underlying zoning district, but all such uses, activities and/or development shall not increase the base flood elevation.

All new construction and substantial improvements to existing structures shall have the access driveways elevated to at least the base flood elevation.

All subdivision proposals and other proposed new developments shall include, within such proposals, base flood elevation data.

In Zones A and AE, 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 only be used for parking of vehicles, building access, or limited storage of maintenance equipment.

There shall be no filling of any floodplain unless approved by the Director of Environmental Engineering and an approved land disturbance permit, building permit, improvement sketch, subdivision or site plan is on file.

Filling in the base flood area shall be prohibited to make a building lot for the purpose of constructing a residential dwelling unless permitted by a variance.

Provide a minimum of two openings on different sides of each enclosed area subject to flooding. The total net area of all openings must be at least one square inch for each square foot of enclosed area subject to flooding.

All existing manufactured homes (in parks or on individual lots/parcels) located in the base flood area shall be anchored to resist flotation, collapse or lateral movement by providing over-the-top and frame ties to ground anchors.

All new construction and substantial improvements of nonresidential structures and accessory buildings within the floodway fringe shall either have a minimum floor level of one foot above the base flood elevation, or be designed to be watertight at least one foot above the base flood elevation.

New construction or substantial improvement of any residential structure (including manufactured homes) in Zones AE and A with detailed base flood elevations shall have the lowest floor, including basement, elevated to a minimum of one foot above the base flood level.

The placement of new manufactured homes on individual lots or parcels adjacent to the base flood area... shall require that stands or lots be elevated on compacted fill or on pilings so that the lowest floor of the home will be at least one foot above the base flood elevation of the nearest A zone and be set back at least 25 feet horizontal distance from the outermost boundary of the base flood.

The placement of new manufactured homes on individual lots or parcels, the construction of new manufactured home parks and manufactured home subdivisions, and the expansion or substantial improvements to existing manufactured home parks and manufactured home subdivisions shall be prohibited within the base flood area.

All uses, activities and development occurring within any floodplain district shall be undertaken only after the issuance of a land disturbance and/or building permit.

No residential dwelling shall be permitted on parcels recorded after March 16, 1983, that are located within the base flood unless approved by the Director of Environmental Engineering through the variance process.

One residential dwelling is permitted on each parcel that was recorded as of March 16, 1983, that is at least 95% inundated by the base flood and that is located within the base flood, provided it shall have a minimum floor level, including basement, of one foot above the base flood and cause no increase in the base flood elevation.

The modification, alteration, repair, reconstruction or improvement of any kind to a structure and/or use requiring a building permit located in any Special Flood Hazard Area district, to an extent or amount of less than 50% of its value... shall be elevated to the greatest extent possible.

While the granting of variances generally is limited to a lot size less than one-half acre, deviations from that limitation may occur.

All new construction and substantial improvements of residential dwellings adjacent to the base flood area/backwater shall be set back at least 25 feet horizontal distance from the outermost boundary of the base flood area/backwater and have a minimum lowest floor level, including basement, of one foot above the base flood elevation.

In the Upper Swift Creek Watershed, all new construction of and substantial improvements to residential dwellings shall be setback at least 35 feet horizontal distance from the outermost boundary of the 100-year floodplain where the contributing drainage area exceeds 100 acres.
