Challenge

In 2017, MSK worked with the Town of Shaftsbury to redevelop the Town’s public works and transfer station facilities. Prior to the redevelopment, there was limited stormwater management on site.

Solution

MSK provided site development, wastewater system design, stormwater management planning, and permitting services. The site design for the garage included the demolition of two dilapidated houses, the relocation of the attendant’s hut, and the reorganization of other existing elements of the transfer station for the temporary storage of waste. We helped the client obtain a stormwater operational permit and a construction general permit, as well as an amendment to the solid waste permit held by the Town. 

Our stormwater management plan was developed for almost one acre of existing impervious surface and an additional acre of new impervious surface. Our design also included impervious swales to direct runoff to pretreatment sand forebays and sand filters for treatment and infiltration. A dry pond downstream of the sand filtration zone mitigates runoff from high-volume storm events. Following survey and design, we managed the bidding process and oversaw construction administration. 

Results

The redeveloped site includes a new transfer station, a highway garage, a salt shed, a pole barn for municipal equipment storage, a salt/sand pile, a parking lot, a fuel storage site, and a sitewide stormwater management system where there had previously been none. Construction was completed in 2019.
