Project Sheet

Location: Washington County, Narragansett and South Kingstown, RI, US

Year: 2016 (ongoing)

Project Type(s): Habitat restoration

Project Description: This restoration project encompasses 14 acres of degraded tidal marsh on the eastern shore of the Narrow River Estuary, RI. A combination of sea level rise and storm impacts from Hurricane Sandy resulted in the degradation of this tidal salt marsh. The addition of dredged material to 14 acres of degraded salt marsh occurred in the winter of 2016-2017. Areas of marsh with signs of stressed vegetation and expanding pond areas were targeted to receive sediment. The sediment was obtained from channel dredging for eelgrass restoration in a nearby tidal flat. The sediment was mainly composed of fine sands, with some fines present. Sediment was placed on the marsh surface using mechanical methods to reach target elevations for high marsh habitat. Extensive monitoring prior to restoration and construction was completed and will continue as the salt marsh recovers.
