No Net Loss Forest Grid Overlay

The Coastal Zone Management (CZM) rules at N.J.A.C. 7:7-13.5 and the Flood Hazard Control Act Rules at N.J.A.C. 7:13-4.2, set forth two methods for determining if a site or portion of a site is forested.  If an area includes areas of sporadic coverage that the applicant asserts do not constitute forest area, the rules direct the applicant to overlay a grid system on the photograph(s) to determine whether such areas contain sufficient coverage to be identified as forest.

Please contact the Division of Land Use at 609-777-0454 for more info on acquiring the grid system overlay.

Grid system method to determine if a portion of a site is forested:

1.The limit of the forest shall be identified using aerial photographs obtained from the Department at; and


2. If the aerial photograph contains areas of sporadic coverage that have not been identified as forest by the applicant, the applicant shall overlay a one-half acre grid system provided by the Department by contacting us through the number listed above.


3. For any grid block containing 33 percent or greater forest cover, the limit of the forested area shall be the outermost edge of the canopy of the forest within the areas identified, including the portion of the canopy of the forest that extends outside of the area analyzed.


Please refer to the regulated identified above, for the second method which consists of analyzing 25-ft plots.
