The town of Wilton, the City of Norwalk and Friends of the Norwalk River Valley Trail will oversee construction and maintenance of the planned 30 mile recreational path from Calf Pasture Beach to Danbury.  The nonprofit secured a $1.1 million trail improvement grant through the Department of Energy and Environmental Protection to cover 80-percent of the cost for the final leg, between Wilton and Norwalk.  The nonprofit will cover the 20-percent local match.  The project is slated to break ground this spring.
