The Mashpee Department of Public Works will nourish the town side of South Cape Beach on Wednesday, July 21, with 300 tons of sand to repair dunes eroded during Tropical Storm Elsa earlier this month.
The beach will be closed from 7 AM until 4:30 PM on Wednesday.
Almost half of the dune that protects the parking lot was lost during the tropical storm that buffeted Cape Cod with heavy rain and wind on July 9, Catherine E. Laurent, the Mashpee director of public works, said.
“The remaining dune is unstable, so even though people are cautioned to stay off it, there are safety concerns,” Ms. Laurent said. “In addition, with the dune being compromised, the protection offered against future storms is adversely impacted.”
Hurricane season lasts through the end of October. A municipal vulnerability report published by the town last year identified South Cape Beach as an area of concern that will be impacted by climate change, including coastal erosion from storms and sea level rise.
