This stormwater project was to repair a failed and severely eroded outfall that drains stormwater from the Town Municipal Office Complex to Smith Hollow Creek. As part of the design project, Hoyle Tanner created and modeled the contributing drainage area to confirm hydraulic characteristics of the system. Final design replaced the failed corrugated metal pipe, incorporated a stone lined plunge pool to dissipate velocity and provide stabilization, and regraded the steep slope to allow access to the practice for operation and maintenance.The new design will prevent the continued erosion of sediment and with it, phosphorus loading to Lake Champlain. The project was constructed in summer 2021.
