Article 7: Subdivisions Section 7.8: Access and Roadways Orange County, North Carolina – Unified Development Ordinance Page 7-16 iii. All lots must be at least 60,000 square feet (1.38 acres) in subdivisions providing 50% or greater open space. c. Minimum building setbacks for lots located on a private road shall be twice those required. (b) The retention and/or provision of landscaping and use of clustering of dwelling units to: (i) Screen the view of the subdivision from public roads, (ii) Maintain a wooded or forested character, (iii) Maintain scenic views, or (iv) Preserve wildlife, botanical, historic, archaeological and/or recreation sites; and/or (c) The preservation of site features which directly enhance the special or unique cultural, historical, archaeological or biological characteristics of the immediate area as referenced in: (i) “An Inventory of Sites of Cultural, Historic, Recreational, Biological, and Geological Significance in the Unincorporated Portions of Orange County” or, (ii) For historic sites, if the site is deemed eligible by the State Historic Preservation Office for inclusion in the National Register of Historic Places. (2) The number, location and/or size of lots to be located in the subdivision are such that, even if constructed to State standards, the streets would not be accepted by the State for maintenance due to density or other State requirements. (3) At least 50% of the site is to be dedicated and preserved through restrictive covenants and contains recreation and/or open space areas of significant botanical, wildlife, historic and/or archaeological sites as referenced in “An Inventory of Sites of Cultural, Historic, Recreational, Biological, and Geological Significance in the Unincorporated Portions of Orange County.” (4) In subdivisions proposed to be located in a Watershed Protection Overlay District, as designated in Section 4.2 of this Ordinance, stream buffers are increased by at least 25% above those required by Section 6.13 of this Ordinance and the impervious surface allowed is decreased by at least 15% to allow greater infiltration of storm water runoff to prevent the pollution of water supply reservoirs. (5) The site contains topographic and environmental features, such as streams, steep slopes, or watersheds that would be adversely affected by the use of roads constructed to State standards because of factors such as significant amounts of earthwork (cut and fill) that would contribute to increased run off of stormwater and siltation. (6) The site is already developed to 100% of the capacity which could be achieved after approval of the subdivision and some or all of the non-conforming aspects of existing development on the site will be made more conforming as a result of the proposed subdivision, and all conforming aspects of the development will remain conforming. (7) There is only one subdivision road proposed and: (a) Its length does not exceed 350 feet, (b) It serves no more than five lots, (c) Its grade does not exceed 9%, and 40
