§ 153.313 PLANNED UNIT DEVELOPMENT.
   (A)   Intent. A planned unit development (herein after “PUD”) is defined in § 153.002 of this chapter. It is the intent of the town to encourage the development of larger parcels of land with greater density and greater degree of consideration of physical features and natural constraints, by enhancing community benefits while fostering the most economically productive land use in the process. It is further the intent of the PUD to promote greater flexibility of design so as to provide a higher level of amenities and more creative design than would be possible by development of the land with traditional district regulations and design standards.
   (B)   Uses.
      (1)   Multi-family developments.
         (a)   Multi-family development may be authorized as allowed in this chapter following review by the Planning Board and approval as a special use by the Board of Commissioners.
         (b)   Multi-family development dwellings of five or more units per building may include the following accessory uses designed for residents and guests of the PUD:
            1.   Retail shops, restaurants, clinics, nursing care and daycare facilities. These accessory uses will offer goods and services designed exclusively to meet requirements of occupants and guests for which such establishment is located. There shall be no signs or evidence of such establishment outside the limits of the development. The aggregate maximum square footage of the accessory commercial use structures listed above shall be limited to 5% of the total site area. Occupancy of the commercial use structures shall be in conjunction with completion of the first 50 units or as otherwise approved by the Board of Commissioners.
            2.   On-site accessory uses or buildings to multi-family development dwellings;
            3.   Playgrounds;
            4.   Club houses with assembly areas;
            5.   Swimming pools and tennis courts;
            6.   Town-owned and leased facilities.
   (C)   Special uses. None.
   (D)   Nonconformities. See §§ 153.050 et seq.
   (E)   Building height limits - PUD developments.
      (1)   One-third of the structures may have four levels of living space with an aggregate living space height not to exceed 43 feet measured to the top plate, and a total building height not to exceed 55 feet, to accommodate various architectural roof designs, with no additional living space. In addition, no more than 50% of the number of units may be located in these four-story buildings.
      (2)   The remaining structures shall have no more than three levels of living space, with an aggregate living space not to exceed 35 feet, and a total building height not to exceed 50 feet, to accommodate various architectural roof designs, with no additional living space.
   (F)   Site requirements.
      (1)   Lot dimensions. All parcels shall have a minimum width of 75 feet.
      (2)   Lot area. The minimum building site for a PUD shall be five acres.
      (3)   Density.
         (a)   Generally. Ten units per acre.
         (b)   Density bonus.
            1.   Twelve units per acre may be permitted provided 30% of the total site is maintained as open space. The following conditions shall apply to the required 30% open space:
               a.   Ten percent upland natural vegetation shall be maintained (natural vegetation is encouraged between uses);
               b.   Minimum of 15% common public spaces including walking and jogging trails and other passive recreational activities;
               c.   The remaining 5% can include wetlands calculated into total site area.
            2.   Fourteen units per acre may be permitted provided 40% of the total site is maintained as open space. The following conditions shall apply to the required 40% open space:
               a.   Fifteen percent upland natural vegetation shall be maintained (encouraged between uses);
               b.   Minimum of 20% common public spaces including walking and jogging trails and other passive recreational activities;
               c.   The remaining 5% can include wetlands calculated into total site area.
         (c)   Calculation. Formula for density calculation when wetland soils are a portion of any lot. Soils classified as wetlands shall be factored into density calculation based on the following schedule:
            1.   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 density.
            2.   If the lot has between 25% to 50% of its total area in soils classified as wetlands, then 50% of that area classified as wetlands may be used in calculating density.
            3.   If the lot has between 50% and 75% of its total area in soils classified as wetlands, then 25% of that area classified as wetlands may be used in calculating density.
            4.   If the lot has 75% or more of its total area classified as wetlands, none of that area classified as wetlands can be used in calculating density.

         (a)   Maximum allowable lot coverage by principal use, all accessory structures, vehicular area and parking–50%.
         (b)   Formula for lot coverage calculation when wetland soils are a portion of any lot. Soils classified as wetlands shall be factored into lot coverage calculations based on the following schedule:
            1.   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.
            2.   If the lot has between 25% to 50% of its total area in soils classified as wetlands, then 50% of that area classified as wetlands may be used in calculating lot coverage.
            3.   If the lot has between 50% and 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.
            4.   If the lot has 75% or more of its total area classified as wetlands, none of that area classified as wetlands can be used in calculating lot coverage.
         (c)   Lot coverage within an estuarine area of environmental concern (AEC), as defined by the Coastal Area Management Act (CAMA), shall be limited to 20% and a minimum setback from the estuarine waters shall be 50 feet. (Exceptions: boardwalks, gazebos, and other pedestrian access structures shall be permitted within the 50-foot setback but must be in accordance with CAMA regulations.)
