Alley Creek CSO Long Term Control Plan

DEP completed a Long Term Control Plan (LTCP) to better understand CSO impacts on water quality within Alley Creek. 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 Alley Creek LTCP and other improvement projects, download the factsheet.

The Alley Creek Long Term Control Plan was submitted to the New York State Department of Environmental Conservation (DEC) in June 2013, resubmitted in November 2013, and resubmitted again in June 2014. DEC approved the plan on March, 7 2017.
