The Coast Guard is establishing a temporary safety zone for navigable waters within a 500-yard radius of the Oceanside Pier. The safety zone is needed to protect personnel, vessels, and the marine environment from potential hazards created by first responders and repair work to the pier. Entry of vessels or persons into this zone is prohibited unless specifically authorized by the Oceanside Fire Department Fire Chief or the Captain of the Port, Sector San Diego.
