According to the latest FEMA flood panels, portions of this property are located within the flood plain (Zone AE; see attached FEMA Flood Map for information). Referencing the NC Surface Water Classifications, the property drains to Midway Branch which has a stream classification of C; Sw (Index #15-25-1-6-1) and is within the Lumber River Basin. The Developer (Pine Forest Development Company, LLC) plans to install a gravity sewer system to serve the first phase of the Hawthrone at Pine Forest apartments, the first phase will consist of 156 apartments and amenity with the flow totaling 24,230 gpd. The gravity system will tie into the permitted and under construction WQ0039987 Pine Forest Planation Development via an 8-inch gravity main and go into the internal PS in the permit above. The total length of line for this phase is 1861 LF. From this pump station, the sewage would then be pumped by way of an 8" force main to an existing sewer manhole just west of US Hwy. 906 (Midway Rd SE) along the entrance road to Lowes Food Market. Designed for future connections, there are extensions of'the gravity sewer system across the existing wetlands in the southwest corner of the development and along proposed `Street A' crossing Pine Forest Boulevard.
