Project Description
This project built a new major waterfront park next to the Pier 70 shipyard, along Illinois Street in the Dogpatch/Potrero neighborhoods. Crane Cove Park was integrated with the restoration of historic maritime structures, as planned in the Pier 70 Master Plan. The initial park plans included cleaning up and stabilizing the shoreline, restoring historic cranes and providing historic interpretation, as well as creating bay access and a human-powered boating facility.
Major Challenges
This was a high-profile project in the heart of San Francisco’s new neighborhood development around the Chase Center. Accessing the site with trucks and barges was challenging. The tidal work and shallow water meant the construction team had to work from both land and sea to build the new beach. The first phase used 3,000 tons of rock and 5,000 tons of sand delivered by truck and installed with heavy equipment. The second phase used a crane barge, excavator, and material barge to place 2,000 tons of rock from the water. The shallow water required the team to retreat with the tides daily to avoid getting their equipment stuck or damaged.
Project Highlights
Crane Cove Park Beach was the first new beach built in San Francisco in decades. It provides direct access to the bay for the community to swim, kayak, paddleboard, and recreate in the protected cove. Dutra also installed 4 EcoConcrete Tide Pools in the riprap on the north side of the cove as an educational feature and point of interest.
Project Scope
Dutra’s part of the Crane Cove Park project was to construct the new beach next to the park. They installed geotextile fabric and capping stone for environmental remediation, and placed thousands of tons of beach cobble and riprap to protect the cove and retain 5,000 tons of new sand. In total, around 5,000 tons of rock and sand were used to build the new beach, along with 4 EcoConcrete Tide Pools to give the community a safe and clean place to enjoy the waterfront.
