GENERAL WATERSHED INFORMATION
Drainage Area - Approximately 0.7 square miles Dominant Land Use - Residential and commercial development Relative Distribution of Land Use - >50% residential and commercial development; other land uses include agriculture and forest Estimation of future land use change - estimated very little changes in land use over the next 10+ yrs; possible changes may include increased residential and commercial areas and highway improvements 5.0
DESCRIPTION OF EXISTING CONDITIONS
Hydrological Features The hydrological features on site include the project reach of the main channel of the UT to Little Coharie Creek, a tributary to the main channel, and two other intermittent drainages into these streams. Adjacent to the project reach is a small seep wetland (approximately 0.1 ac) located on the south side of the main channel. Figure 3 depicts the hydrological features on the project site.
5.1
Soils Soil survey information from Sampson County indicates that the predominant underlying soil layers on the site are Aycock silt loam (1 to 4 percent slopes) and Bibb and Johnston soils (frequently flooded) (NRCS 1985). The Aycock silt loam, a non-hydric soil, is located on smooth uplands near small intermittent streams and is well drained with a moderate permeability. These soils have a silt loam surface layer and sandy loam subsoil. Bibb and Johnston soils, are nearly level poorly drained and very poorly drained hydric soils along major streams. See Figure 4. 5.2
Plant Communities There is one plant community located within the project study area (Figure 5). The observed community consists of successional pasture. The successional pasture community consists mostly of successional vegetation that is impacted by horse grazing. The riparian vegetation along the UTs to Little Coharie consists predominantly of shrubs and early successional vegetation along the banks. Opportunistic trees, shrubs, and herbaceous species along the banks include: tag alder (Alnus sewulata), Chinese privet (Ligustrum sinense), blackberry (Rubus sp.), boneset (Eupatorium pe$oliatum), goldenrod (Solidago sp.), rush (Juncus efSusus), tear-thumb (Polygonum sagittatum), and fescue (Festuca sp.). 5.3
