Subsurface Gravel Wetland, Mansfield Ave.

Essex Junction, Vermont | City of Essex Junction

The City of Essex Junction needed to meet the town’s phosphorous TMDL requirements by designing a subsurface gravel wetland, as proposed by the Indian Brook Flow Restoration Plan. D&K designed a gravel wetland to treat the stormwater discharge from a watershed associated with three homeowners’ associations (HOAs), roadways, and sidewalks. Our project team coordinated with the HOAs, led the design, and provided permitting assistance.
