This project, funded by the Office of Coastal Zone Management’s (CZM) Coastal Resiliency Grant Program, addresses the coastal resiliency of one of Mattapoisett’s most vulnerable low-lying roadways, Mattapoisett Neck Road, which provides the only access/egress for approximately 250 residents who live along the road and on Mattapoisett Neck, as well as a decaying culvert underlying the roadway at Molly’s Cove.

Fuss & O’Neill assessed the vulnerability to future flood risks from sea level rise and coastal storms and developed a set of alternatives to manage risks and improve the long-term resilience of the Mattapoisett Neck Road causeways and Molly’s Cove culvert. This included a combination of roadway elevation enhancements, slope treatments, and culvert alternatives that could be utilized to control flood risks, control costs, and reduce impacts to adjoining resource areas.
