NC Dept of Environmental 1. Sanitary Sewer System Narrative Hatcher Creek Development Oxford, Granville County, NC OCT 13 2021 Site Location and Description Raleigh Regional Offr The purpose of this project is to construct the first four of five sections of a mixed use, planned unit development known as Hatcher Creek, which is in Oxford, within Granville County, NC. The sections included in this portion of the project are the Main Boulevard, the Apartments, the Townhomes and the Single Family. The Apartments propose 288 units and a Clubhouse, the Townhomes propose 108 units, and Single Family proposes 27 units. Future development includes a Commercial section that is part of the development and an offsite future Single -Family residential section, which are north and west respectively of the Main Boulevard. These future sections are not part of this submittal, but the proposed pump station is sized for their potential future flow. The property is owned by Hatcher Creek, LLC. The project drains to both Hachers Run (C;NSW) and Fishing Creek (C;NSW), with the southern portions draining to Hatchers Run, with the northern portions draining to Fishing Creek. The entire project is within the Tar -Pamlico River Basjn (HUC 0302010102). Currently the site is mostly woodlands with a few open areas consisting of bushes and grasses. The surrounding area includes US-15 to the east with undeveloped land further east, to the north is a solar farm, and undeveloped land to west and south. Across US-15 and further south is a Walmart Shopping Center, which is the closest completed development in the area. Sewer Design While the development is one project overall, the ownership of the sewer mains is divided into two sections. The Apartments portion of the project will be privately owned and maintained by Hatcher Creek, LLC and the remaining portions including the pump station will be owned and maintained by the City of Oxford. • The Apartments portion proposed sewer system includes the design and construction of approximately 1,600 LF of 8-inch gravity sewer that will discharge into a proposed manhole within the Main Boulevard. Sewer flow associated with the Apartments totals 80,070 gpd. • The remaining portions of the project that include the Townhomes, Single Family and Main Boulevard includes the design and construction of approximately 4,900 LF of 8-inch gravity sewer, 2,600 IF of 8-inch pressure force main, and a pump station. Sewer flow associated with the remaining portions of the project totals 42,120 gpd. This project is not within the floodplain and no proposed gravity sewer manhole is within 50 feet of any wetlands. The project does include wetland impacts for gravity sewer installation which has been permitted. See attached issued permits from the Army Corps and NCDWR. The Apartments, Townhomes and Single Family will flow via gravity sewer to the pump station in the southwest portion of the project site and will then be pumped via the pump station and forcemain back out to US-15 to connect to an existing 8" forcemain that flows to the existing City of Oxford Wastewater Treatment Plant (WQCS-0086). The project proposes 122,190 gpd of sewer flow be added to the Treatment Plant, which will put the plant's capacity up to 89% of its permitted flow. f ti, O -' t 1. `, ` O 1 f \ • / a Z ) i If t cc P. i I a ° / V .'

As noted in the attached narrative, this project includes in developments but two owners. One being the City of Oxford and the other being Hatcher Creek, LLC. To our knowledge the proposed project will meet all of DWR's minimum design criteria for sanitary sewer extensions. The daily design flow rate for this project is calculated at 122,190 GPD based on NCAC 2T Rules for wastewater flow rates. The proposed sanitary sewer line sizes are more than adequate to convey the design flow rates.
