Critical Environmental Areas

CEAs

Critical Environmental Areas (CEAs) are areas in the state which have been designated by a local or state agency to recognize a specific geographical area with one or more of the following characteristics:

Wooded Wetland Near Storm King
  • A feature that is a benefit or threat to human health;
  • An exceptional or unique natural setting;
  • An exceptional or unique social, historic, archaeological, recreational, or educational value; or
  • An inherent ecological, geological, or hydrological sensitivity to change that maybe adversely affected by any physical disturbance.

A CEA designation serves to alert project sponsors to the agency's concern for the resources or dangers contained within the CEA. Once a CEA has been designated, potential impacts on the characteristics of that CEA become relevant areas of concern that warrant specific, articulated consideration in determining the significance of any Type I or Unlisted actions that may affect the CEA.

Contact the designating agency for additional information on a specific CEA.

CEA Maps: viewing and printing

CEAs can be viewed on the DECinfo Locator, an interactive mapping application with more than 65 data layers available to the public. The DECinfo Locator also has mapping tools available to create and print your own map.

  3. Place a check in the box for Critical Environmental Areas and zoom to the location you're interested in. As you zoom in, the CEAs will appear on the map.
  4. Click on the CEA and information about that CEA will appear in a pop up box.
  5. Center the CEA as you would like it to appear on your map.
  6. Click on Tools near the top of your screen along the left side.
