Boston Mayor Martin J. Walsh and Jackson Square Partners recently announced three milestones marking the final phases of development in the $250 million Jackson Square Redevelopment Master Plan, conceived and developed over a decade ago:

• The $21 million Jackson Commons, comprised of a 37-unit, mixed-use and mixed-income housing development near the Jackson Square MBTA stop, has been completed. Eight units are reserved for homeless/formerly homeless residents earning no more than 30 percent of average median income (AMI). The remaining 29 units are affordable to residents with income limits of 60 percent AMI to 110 percent AMI. The development also has more than 10,000 square feet of ground-floor retail space. The redevelopment consisted of the adaptive re-use and renovation of the 100-year-old Webb Building.
• Ground has been broken at 75 Amory Ave., marking the third phase of a $16 million development that will create 39 units of affordable housing for families. The site is being developed by the Jamaica Plain Neighborhood Development Corp.
• The U.S. Environmental Protection Agency awarded the city $200,000 in brownfields grant for the remediation of the former industrial sites next to Jackson Commons, at 1542 Columbus Avenue in Roxbury. This land will be transformed into a recreation center for the neighborhood.

“I am proud that the city of Boston has invested funding into the redevelopment of these once vacant and underutilized public and private parcels,” Walsh said in a statement. “I want to thank the EPA for this grant to help us move forward with the process of restoring the land to a useful state, and our partners for working with us to create transit-oriented housing that will knit the Roxbury and Jamaica Plain neighborhood together.”
