      (B)   Additional Regulations

         (1)   TR and RMF Districts: Roadway Setback Requirements

            Where parking is provided between the dwelling and the roadway, the length of the driveway and front setback shall be at least eighteen (18) feet, as measured from the public right-of-way. For townhouses and semi-detached/attached dwellings that are part of a development plan submitted prior to May 7, 2020 and subsequently approved in accordance with G.S. 143-755, the length of the driveway and the front setback may be measured from the inside edge of the sidewalk, or the back of curb where no sidewalk is provided.

            When townhouses and semi-detached/attached dwellings have driveways on alleys, the front roadway setback shall be a minimum of ten (10) feet. If townhouses and semidetached/attached dwellings with driveways on alleys provide street trees in coordination with on-street parallel parking at a ratio of at least one (1) tree per two (2) spaces, then the front setback shall be a minimum of seven (7) feet.

         (2)   TR District: Roadway and Rear Setbacks for Detached Dwellings and Patio Homes

            On thoroughfare, collector, or other streets, the width of the roadway and rear setbacks combined shall equal at least thirty-five (35) feet and any individual setback shall be at least three (3) feet.

         (3)   TR and RMF Districts: Roadway Setbacks for Duplexes, Subdivided Attached, Semi-Attached, Townhouse Units and Multi-Family Structures

            The width of the roadway or front and rear setbacks combined shall equal at least twenty (20) feet and any individual rear setback shall be at least three (3) feet.

         (4)   Firewall Requirements for Individual Dwelling Units

            A building setback of less than three (3) feet may be permitted where firewalls are provided in accordance with all applicable building code requirements and where it is permitted by the zoning district.

         (5)   Permanent Common Open Space Required

            One (1) of the following shall be provided, whichever is greater:

            (a)   Five Hundred (500) square feet per unit as required in Section 8.3.1; or

            (b)   Twenty (20) percent of the total parcel proposed for development, excluding dedicated right-of-way. The Planning Director may allow this requirement to be reduced to ten (10) percent of the total parcel area when this common space preserves significant and healthy trees located outside of required buffers or streetscapes.

         (6)   Individual Enclosed Storage Space

            At least twenty-four (24) square feet of individual enclosed storage space with an external entry shall be provided for each dwelling unit in a multi-family development.

            This subsection applies only to Townhouses and Semi-Detached/Attached dwellings.

            Dwellings that have driveways on alleys shall have a minimum building separation of twenty (20) feet. All other dwellings shall have a minimum building separation of twenty (20) feet if there are four (4) or fewer attached units per building, and a minimum building separation of twenty-five (25) feet if there are five (5) attached units per building. (See Section 5.2.1.(L)(4) for additional information regarding building placement.)

            For such dwellings that are part of a development plan submitted prior to May 7, 2020 and subsequently approved in accordance with G.S. 143-755, more than five (5) units may be attached, and the building separation may be a minimum of sixteen (16) feet.
