The Changing Shape of Sandy Neck Beach Park, Barnstable & Sandwich

Sandy Neck Beach Park encompasses more than 4,700 acres of land in West Barnstable (and a small portion in Sandwich) overlooking Cape Cod Bay and Barnstable Harbor. Boasting six miles of shoreline, the park features vast beaches, massive sand dunes, forests, marshland, and the historic Sandy Neck Lighthouse, which dates back to 1857. Every year an average of 120,000 to 150,000 visitors flock to Sandy Neck—many via all-terrain vehicles—to enjoy these unique attractions.
Since 1978, Sandy Neck has been designated an “Area of Critical Environmental Concern” by the Mass. Office of Energy and Environmental Affairs because several endangered species including piping plovers and least terns make their habitat in the area. Officials in Barnstable and Sandwich, as well as all the beachgoers who love Sandy Neck, have also been concerned in recent years about another issue pertaining to the area: erosion.
“The last five years are the worst we can remember,” Sandy Neck Beach Park manger Nina Coleman says of erosion’s impact on the area. Prior to that, she says the dune system on Sandy Neck’s Cape Cod Bay side was relatively stable, experiencing only the natural annual cycle of losing sand in winter, gaining it back in summer. The Town of Barnstable helped manage any endangered areas through the use of sand fencing and vegetation. Mother Nature then stepped in, though, causing severe damage during Hurricane Sandy in 2012 and Winter Storm Juno in January of 2015. Following Hurricane Sandy, the Town of Barnstable hired Coastline Engineering, a civil and marine engineering firm with an office in Marion, to provide dredging and consultation services for several problem areas in town, including Sandy Neck.
According to Christine Player, Coastline’s senior project manager, the area of greatest concern at present is the beach’s lower parking lot, which runs parallel to the shore. Player says the dune system standing between the beach and the lower lot—and to a lesser degree, the upper parking lot—has eroded significantly as a result of the recent storms. During Juno, the eastern end of the beach in front of the lower lot lost 30 feet of “sacrificial sand,” or sand the town paid to have trucked in and dumped on the beach as a dune-replenishment tactic. The idea is that this sand could be “sacrificed” or washed away in a storm, rather than the dunes. In the winter of 2013-2014, more than 20 feet of sacrificial sand in front of the upper lot was swept away, threatening Sandy Neck’s septic system. “The trend of where we lose sand changes year by year,” Coleman says.
As of early April, no manmade structures were in imminent danger. However, Coleman says more erosion in the area could threaten visitor access to the parking lot. “We’re working very hard to keep from losing the parking lots,” Coleman says, “but if there is a very large storm, and the lots are damaged, there wouldn’t be enough spaces for the summer beach season.”
