B. Ex;Usting Environment Topography and Soils. The planning area, as well.as the. project site, Is located within the eastern part of the Piedmont physiographic province, which consists generally of rolling to hilly land sloping to the southeast. However, the planning area can be characterized as being relatively flat. The planning area covers the Town of Carrboro, the City of Durham and Town of Chapel Hill, as well as portions of Durham County and Orange County. There are twelve major soil associations and about one-half of the soil types are considered moderately well drained to poorly drained soils. The number of soil associations is well distributed through- out the planning area and the similiar characteristics permit the variods associafigns to be grouped. The White Store/Creedmoor/Mayodan/Granville/F.rinceton group is moderately well drained with a surface layer of. fine sandy loam and a subsurface of silty clay loam. The Chewacla/Webadkee/Congaree group is somewhat poorly drained to well drained with a surface of fine sandy loam and sub*surface of sandy clay loam. The Irdell/Mecklenburg group consists of well drained soils that have a surface layer of gravelly loam and a subsoil of clay loam. The Georgeville/Herndon/Mason/Tatum/Davidson soils are well drained soils that have a surface layer of silt loam and a subsoil of silty • clay loam. The Appling/Cecil/Louisburg/Helena/Vance soils are well drained to moderately well drained that have a surface of sandy loam and a subsoil of sandy clay loam. The soils associated with the project site are Herndon and Lignum, and they are moderately wi_-11 drained with a surface layer of silt loam and a subsoil of silty clay loam. Surface Waters. The planning area covers parts of the Reuse Riveir and Cape Fear River Basins. The Cape Fear River Basin is located in the southwestern part of the planning area and sub-basins 05 and 06 cover portions of the planning area. The proposed project site is located. in sub-basin 04 of the Cape Fear RiVer Basin. The main stream of this area is that portion of the Haw River.from Mutes Creek down to its confluence into New Hope River. The largest tributaries are Cane Creek, Terrill Creek and Dry Creek. The tributary in proximity to the proposed sludge site is Collins Creek and this tributary runs into Haw River. Collins Creek is a Class C stream which is classified for fish and wildlife propagation. There is no sampling station on Collins Creek but the available information on the Haw River indicates water quality is being maintained for the current classification level. From its headwaters to its confluence with Haw River, New Hope River is the dominant drainage stream in this portion of the plan- ning area. New Hope River is a class C stream and the waters are meeting the required water quality standards. -2-
