An exposed sanitary sewer pipe in the portion of Tryon Creek that flows through Tryon Creek State Natural Area was a threat to water quality and habitat. Environmental Services repaired and protected the exposed sewer, stabilized the stream banks and laid back the banks to the banks to increase flood area and allow the stream to meander.

The project included adding erosion protection and enhancing the adjacent wetland and riparian areas. Gabions (cages filled with large rocks) installed along about 100 feet of stream bank were increasing flow velocity. The project removed them and replaced them with large wood to slow flow, increase in-stream complexity and improve habitat. Environmental Services completed the project in 2011.
