Where the distressed Lincoln Square Apartments once stood, the city's Community Redevelopment Agency will build a neighborhood. And in what is becoming an accepted tactic for blight-fighting projects in the 4,500-acre Midtown Community Redevelopment District, the city won't select a developer and then heavily subsidize its project. Instead the city will be the developer as it is with the Mass Market conversion of the former Salvation Army shelter site on Massachusetts Avenue.
