The state Bond Commission will vote Thursday on hundreds of millions of dollars in grants and funding for efforts and initiatives across the state, including $12 million for the city of Middletown’s ambitious plan to revive its industrial riverfront. The Bond Commission is scheduled to meet in a special session Thursday. Items placed on the agenda can be generally confident of passage. Aid to projects can additionally be subject to conditions required by the state Department of Economic and Community Development and other agencies. In Middletown’s case, the planned $12 million allocation was teed up by a new “Community Investment Fund” board led by state lawmakers. The funding is meant to help the city further its plans to transform 220 acres of dormant industrial land along the Connecticut River with new parks, community spaces, restaurants, retail and multifamily development.
