(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, cottage courts, cluster homes. The maximum floor area ratio (FAR) shall be up to 0.50, exceptions described in division (D) below.
(2) Hotel and motel: For any hotel/motel development, the maximum floor area ratio (FAR) shall be up to 0.50; exceptions described in division (D) below.
(D) Exceptions.
(1) 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 § 153.181;
(2) Per division (C) above, increase minimum required side yard setbacks by two feet on each side, the FAR shall be up to 0.55; and
(3) Per division (C) above, increase minimum required side yard buffer as set forth in § 153.184 by two feet on each side and items in division (C) above the FAR shall be up to 0.60.
(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(D).)
(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) For lots greater than five acres, the use of permeable paving systems, including porous concrete, porous asphalt, concrete grid pavers and permeable interlocking concrete pavers, for parking spaces, drive aisles and vehicular circulations areas, a reduction in the calculated lot coverage shall be allowed. 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 and permeable interlocking concrete pavers with at least four inches of washed stone base - 40% reduction.
4. Porous asphalt, concrete grid pavers and permeable interlocking concrete pavers with at least seven inches of washed stone base - 60% reduction.
(b) For lots less than five acres, 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, a reduction in the calculated lot coverage shall be allowed. Plastic reinforcing grids shall be limited to low-intensity 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), a woven geotextile fabric layer, and 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 grid installations 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.
(c) 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 areas, exceed 75% of the area of the lot.
