Items included in this package consists of, check for $480, FTA 04-16, FTSE 01-16 and USGS Map. This project is called Cambridge Park Phase 2, located on Jones Drive in Mebane, NC. This phase will generate 74,880GPD, it consists of 156 single family lots for sale and is part of a larger subdivision. This project is served by an onsite gravity sewer system (WQ0040482) flowing to a pump station (W00040510) than ultimately tying onto an existing City of Mebane sewer system. Feel free to contact me with any questions or comments.
