Developers unwrap detailed plans for Mattapan Square apartment building

Preservation of Affordable Housing and Nuestra Comunidad Development Corp. recently filed detailed plans for their 135-unit apartment building on what is now a parking lot next to the Mattapan trolley station.

Some 51% of the River Street apartments will be rented to people making 60% or less of the Boston area median income.

The plans call for construction of a nine-unit condo building after the apartments are finished, along with 70 parking spaces for renters, 9 for condo owners and 8 for the stores the developers will rent space to in the apartment building's first floor. The proposal also calls for retaining 50 spaces for commuters using the Mattapan High Speed Line.

The MBTA is leasing the land to the developers for 99 years. According to PoAH and Nuestra Communidad, which will spend $57 million to build the apartments and condos:

The Mattapan Square area is on the cusp of economic and physical revitalization. The upcoming construction of the MBTA's Blue Hill Avenue/Cummins Highway Commuter Rail Station, coupled with the City of Boston's recent implementation of public improvements in Mattapan Square, reflect commitments by the City of Boston and the Commonwealth of Massachusetts to lay the groundwork for the development of transformative projects in this key commercial hub. Moreover, the MBTA's decision to move forward with the development of a transit-oriented development project at Mattapan Station reflects a focused and sustained commitment to establish an environment that will attract future investment. Additionally, the project's mix of residential housing and commercial space will provide additional retail services and support a lively street environment and neighborhood vitality.
