The Beck Group’s Dallas Arboretum Rory Meyers Children’s Adventure Garden is one of the projects competing for the Urban Land Institute award.The operator of the South Bay shopping center in Dorchester is proposing a major expansion that would result in construction of several six-story buildings containing up to 500 apartments, 200 hotel rooms, a cinema, and stores.

Edens Inc., which owns several other East Coast shopping centers, would develop 10 acres to the south of the South Bay complex along Boston Street. Documents outlining the plan were released Wednesday by the Boston Redevelopment Authority.

Residential units would be new at South Bay; currently, it’s solely a shopping complex. Up to 115,000 square feet more retail space is proposed.

Edens also wants to add a 65,000-square-foot cinema and two parking garages, along with new roads and open space around the new buildings. The company has operated South Bay since 1998 and expanded it to Massachusetts Avenue in 2006.

Public officials from Dorchester said they look forward to a thorough community review of the plans and that the project appears to present an exciting opportunity for the neighborhood. Read more
