East Hartford's Redevelopment Agency voted unanimously Thursday night to recommend the Town Council acquire two derelict Silver Lane properties by eminent domain. The parcels, 794-810 Silver Lane and 818-850 Silver Lane, are part of the Silver Lane Plaza, a shopping center with a long history of blight and deteriorating conditions. Town officials have expressed interest in acquiring Silver Lane Plaza, both through good-faith negotiation and by eminent domain, as a part of efforts to revitalize the Silver Lane corridor.
