(4) Dwelling unit structures shall be located and arranged so as to promote privacy for residents within the PRD and maintain privacy for residents adjacent to the PRD. Structures shall be located within the development so that there will be no adverse impact such as excluding natural light or invading the privacy of adjacent structures.
(5) Dwelling unit and other structures located within 200 feet of the perimeter of a planned residential development must be set back by a distance sufficient to protect the privacy of adjacent existing uses. In no event shall a structure be located less than 50 feet from the property line.
(6) Dwelling unit and other structures located near the periphery of the planned residential development shall be designed so as to be harmonious with neighboring areas.
(7) No structure shall be located within 20 feet of the right-of-way of collector streets.
B. Commercial Uses.
(1) All commercial uses shall be located in a single area of the planned residential development which shall consist of at least two contiguous acres.
(2) All commercial uses shall be located with direct access to either a collector or arterial street. If the total parking requirements for such uses in 100 parking spaces or more, the uses must be located on a collector street.
(3) Signs for commercial uses are to be in accordance with
§ 27-504: Sign Regulations of this Chapter.
C. Common Open Space.
(1) The location, shape, size, and character of the common open space shall be provided in a manner consistent with the objectives set forth in
§ 27-505: Planned Residential Development Regulations,
§ 27-5051E, of this Chapter, concerning the conservation of natural resources and the creative use of land to obtain a living environment of stable character, with natural feature constraints determined through the natural features analysis as described in
§ 27-505: Planned Residential Development Regulations,
§ 27-5058A.
(2) The uses authorized for the common open space must be appropriate to the scale and character of the planned development, considering its natural features, size, land use intensity, potential population, and the number and types of dwelling units to be developed.
(3) Whenever possible common open space shall be designed as a contiguous area interspersed with residential areas with pedestrian and visual access available to all residents of the PRD.
(4) Significant natural features such as woodland areas, large trees, natural watercourses and bodies of water, rock outcroppings, and scenic views shall be incorporated into common open space areas whenever possible. However, no less than 25% of the total common open space area shall be suitable for intensive use as an active recreation area.
D. The street system of the planned residential development shall be designed so as to: see
§ 27-5059D.
10. Parking. See "Vehicle Parking", above or
