Coastal Boundary Map

The New York State Coastal Map provides an electronic estimation of the State’s Coastal Area Boundary and identifies: Significant Coastal Fish and Wildlife Habitats (SCFWH); Scenic Areas of Statewide Significance (SASS); Local Waterfront Revitalization Program (LWRP) Communities; Long Island Sound Coastal Management Plan (LIS CMP) Boundary; federally-owned lands; and Native American owned lands.

The coastal boundary was originally created as a set of maps at a scale of 1:48000. This digital representation has been created from the original paper copies through "heads-up" digitizing using geographic information software and the digital NYSDOT planimetric quadrangles at a scale of 1:24000. The official coastal boundary is a written descrtiption contained in the federally approved New York State Coastal Management Program, LIS CMP, and applicable LWRPs.


Authorities:

  • The New York State Coastal Management Program has established statewide boundaries in accordance with the requirements of the Coastal Zone Management Act of 1972, as amended, and its subsequently issued rules and regulations. The Coastal Map provides an estimation of the official New York State Coastal Area Boundary as defined in Section II of the New York State Coastal Management Program and Final Environmental Impact Statement (CMP FEIS). The waterward boundary extends 3 miles into open ocean, to shared state lines in Long Island Sound and the New York Bight and to the International boundary in the Great Lakes, Niagara and St. Lawrence Rivers. Generally, the inland boundary is approximately 1,000 feet from the shoreline following well-defined features such as roads, railroads or shorelines as described in the CMP FEIS, unless otherwise indicated. Where necessary this boundary extends inland to include major state owned lands and facilities and electic power generation facilities which abut on the shoreline, major coastal recreational areas, significant agricultural lands, significant coastal habitats, scenic viewsheds of State or national significance, major historic or coastal dependent industrial areas, and the 100 year flood plain. In urbanized and other developed locations along the coast, the landward boundary is approximately 500 feet from the shoreline or less than 500 feet at locations where a major roadway or railway line runs parallel to the shoreline. The seaward boundary of New York State's coastal area includes all coastal waters within its territorial jurisdiction.
