Project Description: 
This project will reclaim and restore an environmentally degraded site along an important riparian forest corridor by creating wetland habitat, planting native bottomland woods, and removing invasive species. Project location is at the the old Sewer Plant #2 – MKT trail bufferland near Forum Blvd. and Chapel Hill Road. Plans include conversion of the vacated sewer treatment pump house building to a viewing platform with a green roof, as funding allows. Structural engineering analysis and grading work to be contracted. All other work to be done with Park staff and partners.
