OVERVIEW

The MEMA Regions layer represents boundaries used by the Massachusetts Emergency Management Agency for planning and administrative purposes. The data layer is considered unclassified information and was developed to meet Homeland Security Infrastructure Program requirements. The coverage was joined to the MassGIS Towns layer on TOWN_ID by MEMA staff. MassGIS dissolved the layer on region name. The ArcSDE layers and Data Viewer shapefiles are named REGMEMA_POLY and REGMEMA_ARC.

The polygon attribute table contains the following items:
 

Item		Width/Type		Description
NAME		8 / I		Region Name
PHONE		12 / C		Region Phone Number
POP2000		9 / I		Region Population, 2000

The arc attribute table contains the following items:
 

Item		Width/Type		Description
OUTLINE		1 / I		Boundary type:  9 = MEMA internal boundary  1 = State outline  4 = Coastline

The table REGMEMA_POLY_TOWNS identifies which towns fall within each MEMA region. Items include:
 

Item		Width/Type		Description
TOWN_ID		4 / I		Municipality ID, from TOWNS layer
NAME		8 / C		Region Name (same as NAME item in polygon attribute table)

MEMA will provide any updates to MassGIS annually.
