A public meeting is planned for next Thursday (Sept. 22) to review the latest plans for a proposed four story, mixed-use building at 73 River St. in Mattapan.

The proposal, put forth by proponent George Tsolirides, calls for an 18-unit, 23,063-square foot building, significantly smaller than the initial nearly 34,000 square feet detailed in the Article 80 project application.

Architect Lucio Trabucco said the team heard the neighborhood clearly when it asked for additional parking — now 30 spaces are included — and expressed concerns about traffic on Sturbridge Street, which is no longer accessible from their River Street entrance. The project began as rental units but is now entirely condominiums, Trabucco said.

“We are responding to pretty much all the concerns that the people had,” Trabucco said Wednesday.

The building houses a dry cleaners and the River Street Grille, an Italian restaurant. The restaurant will remain a tenant on the first floor.

The BRA meeting is scheduled for Sept. 22 at 6 p.m., in the community room inside 249 River St., Mattapan.
