Each design was conducted as a FEMA funded project in response to damages caused by Tropical Storm Floyd.
The designs included excavation and removal of sediment and debris deposited from Tropical Storm Floyd. In addition, store filling and replacement of rip rap was designed for channel linings and stream embankments. Work included removal of debris with cranes (Bridge Street) and replacement of sewer lines and manholes at Rella Court.
Bank restoration included controlled structural filling, rip rap placement, vegetation and slope stabilization with geosynthetic turf mats and geotextiles. All projects were conducted using US Army Corps of Engineers Nationwide Permits and NYS Department of Environmental Conservation joint water quality certification permits.
