Most of the drainage repair project on Main Street in Danbury is complete. The state has been working to replace piping at Wooster Street to resolve decades of flooding issues. The project on Route 53 is slated to wrap up within days. Danbury Public Works Director Antonio Iadarola says they did have a back and forth with the state on the size of pipe that should be used, but completion is moving forward. Danbury came up with the plans and the DOT replaced a temporary pump installed by the City to test the idea. An investigation revealed that about 100 feet of a nearby culvert collapsed because of tree roots. The storm drain just beyond it is wide open so the City pumped the water there. Then-Mayor Joe Cavo said the operation didn't cause any problems down stream. The blocked culvert was likely constructed in the 1920s.
