The Rockland County Drainage Agency (RCDA) was established under authority of Chapter 846 of the Laws of 1975 to regulate construction and maintenance along designated County regulated streams. In conjunction with the New York State Department of Environmental Conservation (DEC), the Army Corps of Engineers (COE), and local municipalities, the RCDA regulates development and activity along 14 streams - approximately 78 miles - within the County. The Drainage Agency also performs inspections of County Regulated Streams to identify obstructions or damage.
