The Town of Castleton’s salt and sand storage area, municipal highway garage, and transfer station are situated on a 29-acre parcel in the Lake Champlain basin, which has been negatively affected by non-point-source pollution. To comply with regulations associated with the State of Vermont’s Total Maximum Daily Load targets for the Champlain watershed, the Town has been managing erosion on the property for several years. Last fall, the Town of Castleton—with support from the Rutland County Regional Planning Commission and funding from the VTrans Municipal Assistance Bureau—contracted with MSK to improve stormwater management in the salt and sand storage area. MSK is currently developing conceptual alternatives that seek to mitigate chloride contamination, locate a new sand shed to house the existing exposed sand pile, and bring the whole site into compliance with the state’s Three-Acre Stormwater General Permit and Municipal Roads General Permit. We are partnering with the University of Vermont’s Consulting Archaeology Program to conduct the required archaeological and historical resource assessments and Fitzgerald Environmental Associates on hydraulic and hydrologic assessments and stormwater treatment design.
