A Public Hearing Special Town Meeting is being held in Ridgefield tonight about a proposed Demolition Delay Ordinance. Ridgefield residents will vote at the meeting to approve or reject the proposed ordinance, sponsored by the Ridgefield Historical Society and the Historic District Commission. It would give historic preservation a 90-day opportunity to try to save historic buildings. A substantially similar proposed ordinance was defeated previously. The hearing and town meeting are at 7:30pm in the Ridgefield Town Hall Large Conference Room.
