Problem Statement

The site of this project is a degraded, residential stream crossing over an unnamed tributary (UT) to Tom’s Creek that provides access to two private residences. We are working closely with our client and the USDA Natural Resources Conservation Service (USDA-NRCS) to redesign the stream crossing. The existing crossing consists of a double-barrel culvert experiencing problems including erosion around the structure, structural deformation, and perching of the downstream outlets of both barrels.

The purpose of this project is to replace this crossing structure to maintain safe access to the client's private property, alleviate downstream bank instability, allow for aquatic organism passage, and minimize flooding during high flow events. Additionally, we developed management recommendations for the downstream reach on our client’s property which is incised with eroding banks and lacks substantial woody riparian vegetation.
