The boundaries of the wetlands must be first identified and delineated by a wetlands specialist. Delineation methodology includes observation of the soil types, vegetation and hydrologic indicators. To denote a wetlands boundary, pink or blue colored flags are generally placed in key locations. These flags are survey located and shown on a plan in reference to the boundary of the surrounding parcels of land & structures.

Any work that is proposed within 100 feet of a wetland area requires filing with the local Conservation Commission and State Department of Environmental Protection.
