Cross Brothers Dam Removal

The Town of Northfield, in partnership with Vermont Natural Resources Council, is seeking bids to remove the Cross Brothers Dam on the Dog River. The project will generally involve removal of the concrete dam and appurtenant structures, removal of accumulated sediment, stream channel restoration, installation of stone armor at the sanitary sewer crossings and along the north riverbank, and site restoration. • The dam is approximately 107 feet long and 23 feet tall. • The project entails removal of the concrete spillway, intake structure, and approximately 1,800 cubic yards of accumulated sediment upstream of the dam. • A short section of the concrete spillway will be left in place to support the south riverbank and the buildings at the top of the bank. • The concrete floor of the intake structure will remain to protect the sanitary sewer line that is embedded in the concrete. • All other dam components will be removed down to bedrock. • The project will also include installation of stone armor to protect the sanitary sewer pipe, regrading of the sediment bar downstream of the dam, and restoration of the floodplain and riverbanks with riparian plantings.
