“Somerville desperately needs affordable housing and Clarendon Hill needs to be redeveloped,” [Ballantyne] says. “It’s a mixture of affordable and market-rate housing which is so different from the 1970’s model where affordable housing was kept separate. Clarendon is a “social model” as well as an economic one. I think mixing affordable housing and market-rate housing is going to prove extremely successful. This will mitigate some of the gentrification of Somerville.”
