The Waterbury Development Corp. Board, working with the Naugatuck Valley Council of Governments (NVCOG), has assembled brownfield cleanup grants targeting the city's south-end industrial sites — including the former Anaconda American Brass site on Freight Street, the Anamet site along South Main Street, and the Brass City Harvest food hub expansion on Mill and South Main. These projects are remediated and rezoned under state-approved brownfield workflows.
