The DEP Regions layer represents boundaries used by the Massachusetts Department of Environmental Protection for planning and administrative purposes

The layers are named REGDEP_ARC (lines), REGDEP_POLY (polygons), and REGDEP_ANNO_REG (annotation, for region name labeling).

The polygon feature class was updated in August 2021 to be based on the Survey Towns Boundaries (previously based on the USGS-based town boundaries).

Attributes

The polygon attribute table contains the following items:

REGION	DEP Administrative Region
DEP_ID	DEP Region Identifier

Codes are as follows: 

REGION	DEP-ID	Description
WEST	1	Western region - Springfield headquarters
CEN	2	Central region - Worcester headquarters
NE	3	Northeast region - Woburn headquarters
SE	4	Southeast region - Lakeville headquarters

The arc attribute table contains the item OUTLINE, where 1 = state borders, 4 = coastline, and 14 = DEP region boundaries.

 

Maintenance

MassDEP maintains this layer. Boundaries were modified in May, 2006, to reflect the re-assignment of some towns to other regions by MassDEP.

Updated in May 2022 to reflect recent edits to the Municipalities layers.
