Union Point Park
Improvements for the 9-acre waterfront park development on the Oakland Estuary include a 20-foot-high landscaping mound, a pedestrian bridge, an over-water art structure, and other landscaping mounds and improvements. Union Point Park is owned and operated by the City of Oakland. The site was underlain by weak fill and compressible Bay Mud. As the geotechnical engineer, we recommended staged construction of the 20-foot hill to avoid bearing capacity failure of the Bay Mud; for geogrid-reinforcement of the steepened slopes on the hill; and for shallow and deep foundation design for the bridge and sculpture. Langan also managed geotechnical services during construction.
