Welcome to the East of Hudson Watershed

The East of Hudson Watershed Corporation is a local development corporation established by the municipalities in Northern Westchester, Putnam, and Dutchess Counties in the New York City Watershed to install stormwater retrofit projects to meet the requirements for phosphorus reduction defined by the New York State Department of Environmental Conservation (NYSDEC). The Corporation is working in conjunction with the NYSDEC and New York City Department of Environmental Protection (NYCDEP) to further Stormwater MS4 quality projects in the Croton and Kensico Reservoir Basins.


The mission of the Corporation is to reduce the levels of phosphorus in stormwater runoff in the watershed of the New York City water supply system east of the Hudson River (“New York City EOH Watershed”) in order to protect the quality of the waters therein and thereby to achieve compliance with the Municipal Separate Storm Sewer System (“MS4”) heightened requirements in the MS4 permits applicable to the municipalities located within the New York City EOH Watershed (the “EOH Municipalities”).

The Corporation shall carry out the foregoing mission by administering, organizing and implementing a stormwater retrofit program to attain regional compliance with the requirements of the MS4 permits applicable to EOH Municipalities; and by applying for, obtaining and contracting with New York City and any other federal, state, or local government agency, foundation, organization or individual for the purpose of obtaining grants, loans, or other form of financial assistance and expending or authorizing the expenditure of such funds in furtherance of the mission of the Corporation.
