SAN FRANCISCO WATERFRONT STORM DAMAGE REDUCTION STUDY, CALIFORNIA
PROJECT LOCATION AND DESCRIPTION
The primary issue this study will investigate is flooding from large coastal storms, extreme high tide events, liquefaction failure of the San Francisco waterfront seawall from a major earthquake, and sea level rise. The importance of the study is to protect the San Francisco waterfront, including major transportation infrastructures and the City’s financial district, with an estimated $22 billion in public sector assets at risk. Recent inspections along the waterfront have revealed portions of the seawall in need of repair (joints of steel plates and distress of concrete face), and it is at greater risk due to being located in a Seismic Hazard Zone. The seawall is backfilled with liquefiable soils and no section of the seawall is designed to withstand liquefaction. Expected impacts from continued deterioration of the waterfront would include: severed access to passenger ferries; damaged piers, wharves and the buildings on top of them; distorted streetcar tracks; cracks in the Embarcadero roadway and promenade; and disrupted utilities, in addition to risk to health and life safety. At risk is $1.6 billion in property along the Port of San Francisco and disruption of $2.1 billion a year in rent, revenue and wages. The waterfront is a major draw for millions of tourists, who annually bring in about $11 billion.

1 Includes $200,000 mandatory Independent External Peer Review at 100 percent Federal expense per WRDA 2007.
2 The amounts shown are consistent with 3x3. At the appropriate time the San Francisco District will be requesting
an exemption based on the complexity of the study. More information can be found below.
FY 20 AND FY 21 ACCOMPLISHMENTS
On January 31, 2019 the team completed the Alternatives Milestone for the feasibility study, which confirmed vertical team support for the plan formulation work done to date (including the development of an initial array of alternatives), and for the path forward to the next milestone, which is the Tentatively Selected Plan. The team has developed a detailed scope, schedule, and budget for the remaining feasibility phase tasks. The team will determined a future without project condition begin to develop a focused array of alternatives, and will continue to evaluate, screen, and compare project alternatives over the next year to develop a focused array. Towards the end of FY20 a final array will be identified for which the team will conduct detail analysis to determine the tentatively selected plan. The team will prepare the integrated feasibility report, which is currently expected to be released for public and agency review in December of 2021.
ISSUES AND OTHER INFORMATON
The San Francisco District and the Non-Federal Sponsor believe that proceeding with the feasibility study under 3x3 involves many critical risks, and would likely have significant adverse outcomes including poor plan selection and a loss of public trust. The study must sufficiently consider flood risk, seismicity, the impact on utilities, commercial businesses, residents, tourism, and navigation – all across a highly variable and historic urban landscape. At the appropriate time, the San Francisco District will be submitting an exemption request to HQUSACE and ASA(CW).
