What is the MBTA Communities Act?

What are the controversies?


Use this interactive map to explore the potential effects of siting multifamily districts near different transit stations within communities. In addition to providing detailed parcel-level information about current zoning and usage patterns and how these might change if upzoning were to occur, the tool provides relevant demographic statistics about the area surrounding each MBTA station.

Now we compare their zoning, usage, and demographics. The effects of creating a multifamily district near each zone may be disparate or similar. Use this information to determine where a multi-family district siting would be most reasonable for your selected community.

In the area surrounding , there are currently undef% parcels zoned for single family residency, of which undef% are actually used as Single Family. This means that undef% parcels (colored in orange) must upzone in order to comply with the MBTA communities Act, and undef% will likely actually change their use.

WHAT DOES THIS TELL US?

The main takeaway from this analysis is that the impacts of siting a by-right multifamily district vary significantly between municipalities and stations within the same municipality.
We can also see that the population living near Rapid Transit stops are much more likely to take transit to work than those living near the commuter tail. This has implications for the MBTA Communities Act because it speaks to the differences in behavioral patterns of residents living near different communities.

And how is the situation in other municipalities or for other stations?
