This episode unpacks the decades-long effort to dredge Portland Harbor while confronting the legacy of contaminated industrial sediments. Bill Needelman, former Waterfront Coordinator for the City of Portland, Maine, and Michael Johnson, a Project Manager with Stantec, explore how collaboration between city officials, fishermen, environmental advocates, regulators, and engineers led to the creation of Maine’s first confined aquatic disposal (CAD) cell, an innovative solution that made large-scale harbor restoration possible.
