Current Activity

Posted Monday, March 4

Construction for this project is almost finished! The contractor, D.H. Griffin Infrastructure, Inc., finished work on the slope of the dam and added rock in the stream to protect its banks. The last part of the project is to seed the grass, re-open this part of the preserve, and restock the lake (after final approval from N.C. Dam Safety).

The project is expected to be finished in March so work at the lake does not heavily impact park programs. Please note that the dam service road is closed. Visitors will not be able to complete the lower lake trail loop that connects the north and south sides of the park.

Summary

The condition of the dam at Durant Nature Preserve was evaluated by Schnabel Engineering to determine dam safety issues that need to be addressed, including the flow of water downstream of the dam and the stability of the dam's upstream slope. Upgrades will slow down the flow of water coming from the lake, protect the stream below the dam, and make the dam more stable.

This project is being completed in partnership with the Stormwater Management Division and Parks, Recreation, and Cultural Resources Department.
