These two statewide boundary layers are used by the Bureau of Environmental Health (BEH), Massachusetts Department of Public Health (MDPH) for planning and administrative purposes. The source material for these datalayers was compiled by Christina Kara, Emergency Preparedness Bureau, MDPH. The two layers are:
  • Emergency Preparedness Regions - REGDPHEP_POLY
  • Emergency Preparedness Regional Coalitions - REGDPHEPC_POLY. Regional coalitions belong to larger Emergency Preparedness Regions.


Staff at the GIS Program, Bureau of Environmental Health, Massachusetts Department of Public Health developed the data. In Access 2000, the Regional Coalition information was joined to the attribute table of the MassGIS Community Boundaries from Survey Points datalayer based on town name. Using ESRI's ArcMap 9.0 software, a dissolve was performed on the Community Boundaries layer on Regional Coalition name. The new feature class was renamed. In Access 2000, the Region field was manually inserted into the attribute table using the original Regional Coalition information as a reference. To produce the Regions layer, polygons were created based on a dissolve on the Region field in the Coalition layer.


Both polygon layers have the field REGION, which is the MDPH Administrative Region Name. The Coalitions layer also has the field REG_COAL, which is the MDPH Administrative Regional Coalition Name.


MDPH maintains these layers. Users should direct questions to:
