City of Berkeley Completes Southern Waterfront Promenade and Seawall Deck Upgrade at Berkeley Marina

City of Berkeley Parks, Recreation and Waterfront Department engineers reopened 1,350 linear feet of the southern waterfront promenade along Seawall Drive at the Berkeley Marina on Friday morning, completing a $3.4 million shoreline stabilization and public access upgrade adjacent to University Avenue and Shorebird Park. Built to withstand accelerating San Francisco Bay sea-level rise and winter storm-wave overtopping, the modernized walkway replaces cracked asphalt and undermined concrete slabs with marine-grade precast concrete deck panels anchored to epoxy-coated steel tiebacks. Beneath the promenade edge, barge cranes placed 4,200 tons of interlocking Franciscan sandstone armor rock to dissipate wave energy before it scours the marina perimeter.

Along the newly widened sixteen-foot promenade deck, construction crews separated two-way Bay Trail bicycle commuters from sightseeing pedestrians using textured granite paver bands and coastal-grade stainless-steel cable railings that preserve unobstructed sightlines toward the Golden Gate Bridge, Alcatraz, and Angel Island. Fourteen corrosion-resistant dark-sky LED bollards and six sheltered driftwood-style viewing benches were installed at regular intervals between the Marina Office and the southern breakwater turnaround.

In coordination with the San Francisco Bay Conservation and Development Commission (BCDC), marine biologists incorporated textured intertidal tidepool pockets and rough-hewn limestone blocks into the lower toe of the revetment to encourage native Olympia oysters and rockweed kelp colonization. Two new wheelchair-accessible beach-access ramps now lead down to the Shorebird Park cove for kayakers, windsurfers, and environmental education classes from the Shorebird Park Nature Center.

The $3.4 million project was financed through Berkeley Measure T1 infrastructure bond funds paired with a California State Coastal Conservancy Climate Ready grant. Visitors can view marina slip availability, Cesar Chavez Park trail maps, and upcoming autumn nature center workshops on the City of Berkeley Waterfront Portal.
