The sea level along the U.S. coastline is projected to rise 10 - 12 inches on average in the next 30 years, putting homes, businesses, and critical infrastructure at risk.

SumCo is proud to partner with communities and homeowners facing the challenges of shoreline erosion. We have worked on thousands of projects designed to protect and repair our shorelines in the face of storms, wave erosion, and sea-level rise. We have the experience to construct soft or hard shoreline stabilization solutions from a single home to a coastal region.

Coastal protection has been around for many decades. It is not a new concept. What is new, however, are the types of solutions that are now allowed by regulatory authorities.  Below are some Coastal Resilience techniques that our team is implementing along the New England Coastline.

Elcorock Geo Tubes
– Plymouth, MA

The coastal bank protection in this photo is a hybrid “soft” structure. Elcorock tubes are sand filled “pillows” stacked in a terrace configuration going up the coastal bank. Instead of a biodegradable coir material, the pillow is made of geotextile, a non-biodegradable material which has a greater life expectancy and durability. The entire installation is covered with sand and planted with beach grass for a natural coastal bank appearance.

Coir Fiber Roll Installation
– Nantucket, MA

This installation highlights Coir envelopes stacked in an array with posts to help keep them in place. Coir envelopes at this location were the only protection allowed due to dune protections. Dunes under the Wetland Act are meant to furnish sand to the near shore ocean environment. This regulation dictates that coastal protection is limited to “soft” structures in this situation vs a rock revetment (“hard” structure)

Heavy Duty Sand Drift Fence
– Cape Cod, MA

The purpose of the sand drift fence is to accumulate wind-blown sand to naturally rebuild/renourish a dune or the toe of a coastal bank. A “heavy duty sand drift fence” is for locations where waves and surf are particularly intense, and therefore the fence has to be designed to withstand such forces during storm season (winter & early spring). Subsequently, during the non-storm seasons (late spring, summer and fall), the fence can resume its role in naturally accreting sand for restoring/expanding a dune at the toe of a coastal bank.
