MassDEP has released revised/updated versions of two very important documents:

Massachusetts Handbook for Delineation of BVWs

Massachusetts Inland Wetland Replacement Guidelines  

Fillable PDF and Instructions link located on the MassDEP Wetlands Permitting Forms page: https://www.mass.gov/doc/bordering-vegetated-wetland-determination-form/download. The methods in this Handbook should be used in all future delineations of BVW for permitting under the WPA and Bylaw.

Note that MassDEP is proposing new regulations that will update the plant list used for BVW Delineation to the 2020 edition of USACE National Plant List, although the current regulations refer to the 1988 Plant list at 310 CMR 10.55(2). Although this updated guidance refers to the 2020 Plant List, projects under review prior to promulgation of the new regulations should be using the 1995 Plant List in accordance with the regulations.”
