The Danbury Public Works Department has secured all necessary approvals from the ArmyCorp of Engineers and others to start Phase II of the maintenance to the Still River Channel. The plans and specifications are mostly complete for the work between from Patriot Drive and Jansen Street. Approximately 12,800 tons of sediment, accumulated in the river channel over the years, will be removed. Public Works Department officials say the project was bid last month and work is expected to be done when flow in the river is low. The City Council approved a mutual easement agreement with an adjacent property owner in September. The City Environmental Impact Commission and the State DEEP have also signed off.
