Grices Run

Stream Restoration - April 2021

Scope of Work

The Grices Run Stream Restoration will stabilize erosion in an area of the County which has highly erodible soils and uncontrolled runoff from upstream development that was created prior to stormwater management regulations (see attached Existing Conditions photos). The project includes two unnamed tributaries to Grices Run flowing directly into the James River (see attached location map). Reach 1 is a 950-linear-foot channel beginning at a culvert under Columbia Drive and located east of Endeavor Drive. Reach 2 is a 260-linear-foot channel located east of James River Elementary School, near the side parking lot. The goal of the design is to create a channel with a stable pattern, profile and dimension, and stabilize actively eroding banks. Natural channel design principles were utilized to develop the limits for the design. Streambank stabilization structures will be employed in the stream restoration. Invasive plants will be removed and replaced with native trees, shrubs, and herbaceous vegetation. All necessary permits and/or approvals have been obtained for this project.
