Repairs are scheduled to begin next month to the O'Shaughnessy Seawall at Ocean Beach in Golden Gate National Recreation Area/NPS

Decades of salt air, ocean spray, and storms have taken their toll on the O'Shaughnessy Seawall at Golden Gate National Recreation Area in California. The effects -- cracked and spaulding concrete -- will be erased in the coming months as crews repair the wall at Ocean Beach in the NRA.

The work, guided by preservation specialists from the National Park Service's Historic Preservation Training Center, is set to begin in mid-to-late October and run into next March. The repairs are scheduled to include removing and repairing hazardous and broken concrete, replacing hazardous rebar, and prepping and sealing concrete surfaces for later repairs.

NRA officials say the work will impact access to the promenade, but not extensively. "Noise and dust will occur while chipping concrete is in progress. This will only take place during normal work hours, weekdays between 7 a.m. and 5 p.m.," a release from the NRA said.

The seawall was built in five sections, beginning in 1916 and ending in 1929. According to Park Service historians, "the Ocean Beach Esplanade and Seawall on San Francisco's western shore is a remnant from the beach's heyday as a local attraction as well as an example of the prolific municipal progressivism of city engineer Michael Maurice O'Shaughnessy."
