The CRP 3072/5072 Land Use & Environmental Planning field workshop in the Spring of 2018 conducted studies of drainage and stormwater runoff and stormwater management systems in the Patton Brook and Silver Stream watersheds that supply the City of Newburgh’s public water supply reservoir at Lake Washington. The studies are part of a larger response to the contamination of Lake Washington with the chemical PFOS. The goal of the studies was to develop a more holistic approach to stormwater management from all sources, in order to better protect the water supply for Newburgh. Course objectives included providing students with a working knowledge of stormwater runoff calculations, New York State design standards for managing stormwater, and the innovative uses of green stormwater infrastructure in runoff management.
