Middletown is in line for $12 million to fund its “Return to the Riverbend” plan, an effort to make better connections with parkland and redevelop industrial, commercial and waste treatment sites along the Connecticut River. Waterbury is teed up to get $10 million, which local officials say is enough to finish cleaning a roughly 20-acre brownfield adjacent to its downtown. New Haven is the other big winner, with a $10 million allocation Tuesday. This list of projects blessed by the Community Investment Fund 2030 board now needs Gov. Ned Lamont’s approval to go on the state Bond Commission Agenda for funding. But no cuts are anticipated. Approved by lawmakers last year, the Community Investment Fund Board has a mandate to approve up to $875 million in projects and grants in distressed communities over a five-year period.
