The Port of San Diego will be coordinating in-water construction along the south shoreline of Sweetwater Channel in San Diego Bay from August 24, 2026, intermittently through November 25, 2026. Operations are dependent on tidal conditions. The project consists of the removal of existing rock revetment and the installation of interlocking ECOncrete tidepool shoreline units. In-water work will include the use of a floating barge with crane operations and small support vessels at approximately 32-39.00N 117-06.52W. Mariners are urged to transit at their slowest safe speed to minimize wake, and proceed with caution after passing arrangements have been made.
