Highway 54. Both the OWASA and the stone quarry use trucks to haul materials along NC Highway 54. The site itself is undeveloped and heavily wooded. 3.10 Water Resources 3.10.1 Groundwater Resources According to the Water Resources Investigation Report 00 -4286, the primary aquifer in the vicinity of the project area is located in the metavolcanic bedrock. A shallower aquifer exists within the soil zones above the bedrock (e.g., regolith) but is unreliable in quality and quantity. Wells are typically cased at least 50 feet, and the average well yield and depth are approximately 17 gpm and 200 feet, respectively. Wells located in fracture zones generally yield higher than average. Groundwater recharge in the vicinity of the project area (the Haw River Watershed) is 6.4 inches /year or 477 gallons /day /acre. Currently, there is not any potable well on the property. Neighboring residences and farms rely on groundwater for their water source. 3.10.2 Surface Water Resources The project area is located in the Cape Fear River Basin. The headwaters of the basin are the Deep and Haw Rivers. Approximately 1.5 miles on the west of the proposed project site, Cane Creek is located, and located approximately 0.5 miles to the east of the project site is Collins Creek. To the northwest of the proposed site, surrounding the area around the Cane Creek Reservoir, is a tract of land that has been identified by the Orange County Planning Department as being a critical and protected watershed. A Surface Water Identification (SWID) request was filed with the County to determine if the surface waters located near the proposed project site are subject to the stream buffer ordinance as described in the County Zoning Ordinance. At this site, five features were identified as subject to the buffer regulations. This will require a 65- to 80 -foot undisturbed buffer along both sides of the water feature, which will be calculated per the referenced zoning regulations. For the features that originate within the parcel, the beginning point was flagged for reference. All of the features were identified on a map by the County Planning and Inspections Department. There were several isolated pools located in the parcel identified as a sixth feature. Although this feature did not meet the criteria for the stream buffer regulations, it may meet wetland criteria and will require follow up with the United States Army Corps of Engineers (USACOE) (see Section 3.4). The correspondence from the County's Planning and Inspections Department is located in Appendix A. 8 Environmental Assessment Site 056
