Golden Gate National Recreation Area - Stabilize Alcatraz Wharf This project will make critical repairs to and seismically strengthen the concrete wharf on Alcatraz Island, a contributing feature of the Alcatraz Island National Historic Landmark District built in 1939. Work will include repair of the historic, steel-cased concrete piles, concrete beams, and concrete slabs. These elements are in fair to poor condition, with varying degrees of damage. Two new seismic resisting elements will be installed to bring the wharf up to a seismic Risk Category III structure. Concrete repairs and seismic improvements will be undertaken in a single phase of construction.
