Challenge

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.  

Solution

In Fall of 2020, the Town of Castleton—with support from the Rutland County Regional Planning Commission and funding from the VTrans Municipal Assistance Bureau—contracted with us to develop conceptual approaches to mitigate chloride contamination. This was achieved by locating 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 also partnered 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. 

Results  

The stormwater scoping study delivered by MSK in 2022 was able to meet the needs and support the Town of Castleton’s compliance goals.
