Wetlands

Ocean County Subsurface Gravel Wetlands BMP

ATANE provided design, environmental permitting and construction management services for a $6 million stormwater best management practices project that used a relatively new approach of constructing subsurface gravel wetlands to improve water quality for runoff that discharges into Barnegat Bay. The overall program called for retrofitting seven stormwater management facilities with underground wetlands to reduce nitrogen loading to the bay.

ATANE was assigned one of these facilities, which involved analyzing and redesigning an existing stormwater facility to function as a subsurface gravel wetland. The modified facility stores rainfall and routes it through flow control components to clean and remove nitrogen before discharging it. The result was a substantial water quality improvement to each facility while maintaining the flood control capabilities of the basins.

Wetlands

Sunset Avenue Basin Retrofit

ATANE provided design and environmental permitting for the retrofit of the Sunset Avenue Stormwater Basin as part of the Gravel Wetland Stormwater Best Management Practice project in Ocean County.  The project employed subsurface gravel wetlands to improve water quality for runoff that discharges into the Barnegat Bay.

The basin was designed and permitted to be retrofitted with an underground wetland system to help reduce nitrogen loading to Barnegat Bay. The design involved analyzing and redesigning the stormwater facility to function as a subsurface gravel wetland by excavating the basin bottom to provide a combined gravel and pipe system that will store rainfall and route it through flow control components to clean and remove nitrogen before discharging it. The result of the construction will be a substantial water quality improvement of the discharge of this stormwater facility while maintaining the flood control capabilities of the basin.
