Falconhurst Drive Culvert Analysis

December 31, 2026


The principal culvert to be evaluated for this project is located on Falconhurst Drive, approximately 200 feet west of Hampton Chase Court.  A secondary culvert on Hampton Chase Court will also be evaluated in the analysis. Both culverts convey baseflow and stormwater runoff to Toms Branch, a FEMA-regulated stream. Another culvert further east of the primary culvert on Falconhurst Drive will be evaluated.   

The Town has documented heavy sediment deposition within the culverts, causing decreased flow capacity, erosion around wingwalls, and roadway overtopping during the 50-year storm event is predicted in hydraulic models. Potential sources contributing to the sediment issues include undersized culverts and sediment conveyance in Toms Creek and a tributary to Toms Creek. The project is needed to bring the level of service for the stormwater infrastructure in this area to an acceptable level of service to reduce potential roadway flooding and improve culvert and sediment transport capacity.
