19 <br />c. The preservation of site features which directly enhance the special <br />or unique cultural, historical, archaeological or biological <br />characteristics of the immediate area as referenced in "An Inventory <br />of Sites of Cultural, Historic, Recreational, Biological, and Geological <br />Significance in the Unicorporated Portions of Orange County" or ,for <br />historic sites, if the site is deemed eligible by the State Historic <br />Preservation Office for inclusion in the National Register of Historic <br />Places. <br />2. The number, location and/or size of lots to be located in the subdivision are <br />such that, even if constructed to State standards, the streets would not be <br />accepted by the State for maintenance due to density or other State <br />requirements. <br />3. At least fifty percent (50%) of the site is to be dedicated and preserved <br />through restrictive covenants and contains recreation and/or open space <br />areas of significant botanical, wildlife, historic and/or archaeological sites as <br />referenced in "An Inventory of Sites of Cultural, Historic, Recreational, <br />Biological, and Geological Signficance in the Unincorporated Portions of <br />Orange County" <br />4. In subdivisions to be located in a Protected Watershed as designated in the <br />Orange County Comprehensive Plan, stream buffers are increased by <br />twenty-five percent (25%) above those required by Article 6.23 of the <br />Orange County Zoning Ordinance and the impervious surface allowed is <br />decreased by fifteen percent (15) to allow greater infiltration of storm water <br />runoff to prevent the pollution of water supply reservoirs. <br />5. The site contains topographic and environmental features, such as streams, <br />steep slopes, or watersheds, that would be adversely affected by the use of <br />roads constructed to State standards because of factors such as significant <br />amounts of earthwork (cut and fill) that would contribute to increased nan-off <br />of stormwater and siltation. <br />6. The site is already developed to 100% of the capacity which could be <br />achieved after approval of the subdivision and some or all of the non- <br />conforming aspects of existing development on the site will be made more <br />conforming as a result of the proposed subdivision, and all confom~ing <br />aspects of the development will remain conforming. <br />7. There is only one subdivision road proposed. Its length does not exceed <br />350', it serves no mare than five (5) lots, its grade does not exceed 9%, and <br />the land being subdivided is not connected to or part of another subdivision <br />required to be served by public roads. In addition, the average lot size <br />within the subdivision is at least 40,000 square feet. <br />g:\kli ncol n\pvtroads\ordain. d°c\r22-00\kl <br />
