Description:
This layer features the town boundaries in Region 1, along with both their total populations and their regulated populations per MS4 designation. The regulated populations were calculated by splitting the MS4 Regulated Areas by town boundaries (Municipal boundaries of the 6 New England states (USEPA Region 1) from USGS National Boundary Dataset (NBD)), using the "Summarize Within" tool along with census block population data to calculate the population within the regulated areas for each town, and then adding that data to the town boundaries feature class as a new attribute. Due to slight differences in data resolution, estimated regulated population numbers may be off by up to 150 people.

This is a content item is featured in the NPDES Phase II Stormwater Program Designated MS4 Areas mapping application.
