(A) Lot dimensions. All parcels shall have a minimum width of 50 feet.
(B) Lot area.
(1) The minimum building site shall be 15,000 square feet.
(2) The minimum building site for a duplex shall be 15,000 square feet.
(3) Exempt recombination plats for lots platted prior to June 14, 1983 shall have a minimum lot size of 7,500 square feet.
(C) Density.
(1) Multi-family dwelling: 12 units per acre.
(2) Hotel and motel: 36 units per acre.
(D) Exceptions. Where a lot or parcel of land has an area of less than the above required minimum area and was of record on June 14, 1983, such lot may be occupied by one family, provided the minimum side, front and rear requirements are complied with as set forth in § 153.231.
(E) Lot coverage.
(1) Maximum allowable lot coverage by principal use, all accessory structures, vehicular circulation areas and parking - 65%. (For exceptions see § 153.082.)
(2) Soils classified as wetlands shall be factored into lot coverage calculation based on the following schedule:
(a) If the lot is composed of less than 25% of its total area in wetland soils, then 75% of that area classified as wetlands may be used in calculating lot coverage;
(b) If the lot has between 25% to 50% of its total area in wetland soils, then 50% of that area classified as wetlands may be used in calculating lot coverage;
(c) If the lot has between 50% to 75% of its total area in soils classified as wetlands, then 25% of that area classified as wetlands may be used in calculating lot coverage;
(d) If the lot has 75% or more of its total area classified as wetlands, none of that area classified as wetlands may be used in calculating lot coverage.
(3) Permeable pavement lot coverage calculations:
(a) The use of permeable paving systems, including porous concrete, porous asphalt, concrete grid pavers, permeable interlocking concrete pavers, and plastic reinforcing grids for parking spaces, drive aisles and vehicular circulation areas, shall allow for a reduction in the calculated lot coverage. Plastic reinforcing grids shall be limited to low-density applications with low traffic speeds. Examples include, but are not limited to, parking stalls in commercial parking lots, overflow parking areas, utility access, emergency vehicle and fire access lanes, and loading areas. Material to fill the open cells of the pavement system types shall consist of open graded fine aggregate, open graded washed aggregate, sod turf grasses native to the southeast coastal environment and exhibit medium to high permeability rates. All permeable paving systems shall comply with the criteria of the North Carolina Division of Water Quality Stormwater Best Management Practices Manual (current edition). The following calculated reductions are allowed:
1. Porous concrete without washed stone base - 40% reduction.
2. Porous concrete with at least six inches of washed stone base - 60% reduction.
3. Porous asphalt, concrete grid pavers, permeable interlocking concrete pavers, and plastic reinforcing grids with at least four inches of washed stone base - 40% reduction.
4. Porous asphalt concrete grid pavers, permeable interlocking concrete pavers, and plastic reinforcing grids with at least seven inches of washed stone base - 60% reduction.
5. The pavement section shall consist of the surface course or layer for infiltration, a bedding course (as required), an aggregate storage layer, and a woven geotextile fabric layer to prevent clogging.
6. Edge restraints shall be provided on all concrete grid pavers, permeable interlocking concrete pavers, and plastic reinforcing grids to confine the pavement installation. The pavement surface course structural properties shall be designed to withstand the applied vehicular loading pursuant to the specified application.
(b) In no case shall the total area that is occupied and obstructed by any structure above the ground, including but not limited to parking and drive aisles, exceed 75% of the area of the lot.
(F) Drainage/stormwater runoff. All development is required to follow the provisions of § 153.070.
(G) Land disturbance.
(1) General. See § 153.071.
(2) LI-1 Fresh Pond Area of Environmental Control (AEC). Developers shall preserve a maximum amount of vegetation around perimeter of site. Where site configuration does not prohibit, developers shall dedicate 10% undisturbed space along the western boundary of site. Regraded and revegetated areas designed to perform as stormwater retention and management areas shall be constructed in the vicinity of the eastern boundary of site.
