Subregional Adaptation Plan

Announcement: OAAC is holding two informational workshops on the Bay Farm Island Adaptation and Estuary Adaptation projects. The purpose of these workshops is to provide input on the draft concepts for the two projects. For the Bay Farm Island Adaptation Virtual Workshop on Wednesday, December 4 from 5:30-7pm, register here. For the Estuary Adaptation Virtual Workshop on Thursday, December 5 from 5:30-7pm, register here.

What: A long-term Subregional Adaptation Plan that details preliminary strategies and pathways for shoreline communities to take as the climate and shorelines change over time, as required by state law.

Where: Oakland and Alameda shorelines, from the Bay Bridge in the north to the Oakland Airport in the south, connecting with the City of San Leandro. 

Why: To adapt shoreline communities to rising sea levels and groundwater, and to reduce flooding in the long term (2080 and beyond). Adaptation measures also will enhance transportation and bay access, restore habitat with nature-based solutions, and improve air quality.

How: An inclusive community engagement planning process ensures that all voices are heard to better understand the priorities of community members. Since subregional plans are required by state law, the plan is subject to approval by the San Francisco Bay Conservation and Development Commission (BCDC).  The plan is funded by the San Francisco Estuary Partnership (SFEP) and the National Fish and Wildlife Foundation (NFWF). The plan will be completed in fall 2025.

The purpose of the Sub-regional Adaptation Plan is to:

  • Protect shoreline communities of Oakland and Alameda from expected sea level and groundwater rise and liquefaction;
  • Enhance transportation and recreation corridors and bay access;
  • Reduce flood exposure;
  • Create or restore marsh, upland and transitional habitat with nature-based solutions;
  • Improve air quality;
  • Reduce climate risks to shoreline communities throughout the Oakland-Alameda operational landscape unit (OLU)(PDF, 125KB); 
  • Detail key steps and actions to take as the shoreline changes, identifying trigger points and costs for each of the outlined pathways; and
  • Use a decision-making process to ensure the voices of all stakeholders in the Oakland-Alameda Adaptation Committee are heard. 

 

2019

  • Sept: Alameda City Council approved the Climate Action and Resiliency Plan - link to staff report

2020

  • Nov: Alameda City Council accepted the report: “City of Alameda, The Response of the Shallow Groundwater Layer and Contaminants to Sea Level Rise”, which states that the areas at risk of future flooding increase by up to 25 percent when considering emergent groundwater - link to staff report

2022

  • June: Alameda City Council adopted the City of Alameda Climate Adaptation and Hazard Mitigation Plan, which calls out the need for a sub-regional Long-term Adaptation Plan - link to staff report and to Plan
