f . / 1 The requirement of setting aside one-third of the project area as open space represents a mid-range approach. It is slightly higher than one standard considered by the University Station Planning Group (30`X,) and is less than the 40 to 50 percent range cited in many reference materials. The requirement is considered feasible, based on a review of six Orange County subdivisions which provided or are to provide open space. Open space in these subdivisions ranged from 24 to 47 percent of the total project area, with a median of 34 percent. The "one-third"standard is also considered feasible, given the alternatives available for satisfying the open space requirement. The wording at the beginning of this section has been included to clarify that unless a developer chooses to seek approval of a Flexible Development, he/she need not comply with the open space requirements. C.2 Types of Open Space The types of open space conserved through Flexible Development shall be cone with the following standards: a. Open space shall be comprised of two types of land: "Primary Conservation Areas" and "Secondary Conservation Areas". b. Primary Conservation Areas consist of the following site features: • Wetlands, including, but not limited to, streams, creeks, ponds, reservoirs, stormwater management facilities for watershed protection purposes, and adjoining land areas identified as part of: O The National Wetlands Inventory Maps for Orange County, N.C. prepared by the U.S. Fish and Wildlife Service; • The Orangery.N.C. Soil Survey prepared by the U.S.D.A. Soil Conservation Service; • The Inventoryy of Natural Areas and Wildlife Habitats as prepared by the Triangle Land Conservancy; • LANDSAT satellite data collected and analyzed under the Albemarle-Pamlico Estuarine Study; • A required Environmental,Assessment or Environmental Impact Statement; and/or • A site analysis conducted by a registered engineer, Iand surveyor, landscape architect, architect or land player using data from the U.S. Army Corps of Engineers. • Floodplains(100-year)and alluvial soils identified as part of: O The Flood Insurance Stndv: Orange County. N.C. prepared by the Federal Emergency Management Agency(FEMA); and • The Ozaoaely.N.C. Soil Smvev prepared by the U.S.D.A. Soil Conservation Service. • Steep slopes, defined as those greater than 25 percent, identified as part of • The QMM County.N.C. Soil Survey prepared by the U.S.D.A. Soil Conservation Service; and/or • A site analysis conducted by a registered engineer, land surveyor, landscape archntect, architect or land planner and calculated using topogmpluc maps from an actual survey or from the U.S. Gelogical Survey. • Natural areas, and wildlife habitats and corridors identified as part of. • The Inventory of NaftLud Areas and Wildlife Habitats as prepared by the Triangle Land Conservancy; • A required Environmental Assessment or Environmental Impact Statement; and/or • An independent site study conducted by a trained botanist and/or biologist.
