Long Island Sound Coastal Management Program


New York's Long Island Sound coast encompasses 304 miles of shoreline in Westchester, Bronx, Queens, Nassau, and Suffolk counties and its watershed is home to nearly 1.5 million people. Accelerated demands for development, declining water quality in harbors and embayments, and difficulties sustaining a healthy maritime economy, led our office to develop a regional approach to address the coastal management issues unique to Long Island Sound. 

Managing Development Affecting
The Coast of Long Island

The Long Island Sound CMP provides coastal policies tailored to the Long Island Sound shorelines of Westchester County, New York City to the Throgs Neck Bridge, Nassau County, and Suffolk County, replacing the State CMP in those areas. The LIS CMP defines what constitutes a balance between appropriate and needed economic development and protection and restoration of the natural and living resources of the Sound.


The policies are statements that provide standards for Long Island planning, regulatory issues, and community needs. The policies consider the economic, environmental, and cultural characteristics of the Long Island Sound coastal region. They represent a balance between economic development and preservation that will permit beneficial use of and prevent adverse effects on the Sound's coastal resources.
