Gowanus Canal

Gowanus Canal CSO Long Term Control Plan

DEP completed a Long Term Control Plan (LTCP) to better understand CSO impacts on water quality within Gowanus Canal. Throughout the LTCP’s development the City collected water quality data, performed extensive modeling, held multiple public meeting and analyzed potential projects based on costs and anticipated water quality. To learn more about the Gowanus Canal LTCP and other improvement projects, download the factsheet.

The Gowanus Canal LTCP was submitted in June 2015. The New York State Department of Environmental Conservation (DEC) approved the plan on March 29, 2017.
