Port of San Francisco has appointed CH2M and Arcadis to lead the design and engineering for its 10 year Sea Wall Resiliency Project, which is estimated to be worth US$40M (£30.5M).
Through the scheme, a 6km section of century old sea wall will be improved to protect the city’s waterfront from Fisherman’s Wharf to Mission Creek.
Arcadis will lead risk analysis, coastal engineering and modelling while CH2M will provide marine and structural engineering services for the sea wall and other structures.
“The major drivers for making significant improvements to the seawall include earthquake protection enhancements and flood risks caused by climate change,” said Arcadis city executive to San Francisco Peter Wijsman. “Arcadis brings its Dutch heritage of addressing coastal resiliency and its broad experience in civil engineering and coastal protection in urban settings, most recently in New York City and in New Orleans after major hurricanes. This contract win strengthens Arcadis’ water management position on the US west coast.”
The seawall supports historic piers, wharves, and buildings including the Ferry Building. It underpins the Embarcadero Promenade which welcomes millions of people each year and provides flood protection to San Francisco’s Financial District and other neighbourhoods. The seawall also serves as a critical emergency response and recovery area, and it supports multiple municipal transportation systems and utility networks.
