Title

Airport Perimeter Dike FEMA and Seismic Improvement Project

Description

The Airport Perimeter Dike FEMA and Seismic Improvement Project is being completed over two phases at the Oakland International Airport (OAK). Phase 1 was completed in 2021 and included the construction of flood protection measures to meet the standards required by the Federal Emergency Management Agency (FEMA). Phase 2 will construct the improvements necessary to protect the dike from catastrophic damage during a major earthquake and includes new project elements requiring additional analysis and development of the Supplemental Initial Study / Mitigated Negative Declaration (IS/MND) to the original 2015 IS/MND and 2017/2018 addenda. The primary objective of Phase 2 of the APD Project is to maintain the flood protection of the APD system following a major earthquake in the San Francisco Bay Area. Seismic improvements will consist of Cement Deep Soil Mixing (CDSM) and will occur within a 0.75-mile stretch at the western end of the existing 4.5-mile Airport Perimeter Dike. The Project also proposes to place approximately 37,000 CY of material generated from the seismic improvement process across 10 acres at a closed landfill (North Port of Oakland Refuse Disposal Site), a Port of Oakland owned property located adjacent to the Oakland International Airport.
