The City of San Diego’s landmark Climate Action Plan leads in efforts to mitigate climate change through programs and policies that aim to eliminate half of the City’s greenhouse gas emissions by 2035. However, even with strong mitigation efforts, climate change is a global issue with impacts being felt on a local scale. Best available science projects varied impacts of a changing climate for the San Diego region, including:
These climate change hazards can impact the region’s people, economy, infrastructure, and natural environment.
The City of San Diego is already addressing climate change through a wide range of programs:
Climate Resilient SD will be the City’s comprehensive climate adaptation and resiliency plan, which will increase local capacity to adapt, recover and thrive amidst a changing climate.
On Monday, April 19, from 6 p.m. to 7:30 p.m., you can attend a virtual workshop to learn more about the plan and share your ideas on how we can flourish as our climate changes. Click here to register. Live Spanish translation will be available during the workshop.
Learn more about potential adaptation strategies to address sea level rise, extreme heat, wildfire and flooding, and let us know which actions you would like to see the City take for a more resilient and thriving San Diego.
Vision and Goals Survey: Earlier this year, the City created an online engagement tool to provide information on San Diego's changing climate and to hear from you on what you think a resilient and thriving San Diego would look like.
The survey closed on Feb. 19, 2021, but the engagement tool can still be viewed here:
Adaptation is a core component of a comprehensive response to climate change. Strategy 5 of the Climate Action Plan (CAP) calls for a standalone climate adaptation plan to identify vulnerabilities, take early action, integrate adaptation into CAP efforts, capitalize on co-benefits, and increase local resilience. Climate Resilient SD also implements the CAP’s social equity goals by prioritizing our City’s Communities of Concerns to ensure that investments and resources are prioritized for those with the greatest needs and vulnerabilities.
Mitigation focuses on reducing greenhouse gas (GHG) emissions to avoid the worst potential impacts of climate change.
Adaptation focuses on reducing impacts from climate change related hazards.
Resilience enhances the ability to bounce back from a disruptive event.
The City has completed multiple vulnerability assessments to evaluate the risk that climate change related hazards, such as sea level rise, extreme heat, wildfires, and precipitation driven flooding, may pose to City’s assets and resources. These vulnerability assessments will help inform the development of Climate Resilient SD by identifying which assets and resources would be the best candidates for implementation of adaptation strategies. Adaptation strategies are actions that will minimize the vulnerability of an asset, resource, or community to a particular climate change hazard. Adaptation strategies can be education and outreach initiatives, new programs or policies, operational updates, or infrastructure projects.
The City is developing a suite of adaptation strategies to minimize vulnerability to climate change hazards and increases the resiliency of San Diego’s people, economy, infrastructure, and natural resources. To develop Climate Resilient SD, the City will be working collaboratively with community members and stakeholders. Upcoming public outreach will seek input on the proposed adaptation strategies and gather feedback on how you envision a resilient San Diego. Together, we can prepare for and thrive in a changing climate while improving social equity, health, safety, and the environment for all.
The Climate Change Vulnerability Assessment was a key step towards completing Climate Resilient SD. Backed by the best available science and informed by a diverse Stakeholder Advisory Group, the Vulnerability Assessment identified and evaluated which City assets are vulnerable to climate change and the potential consequences that could occur. A high level overview of the findings is presented in the brochure. Read the full report.
The City of San Diego has long recognized the need to address the risks from sea level rise, storm surge, and coastal erosion. To better understand these risks, the City conducted a sea level rise vulnerability assessment with funding from a California Coastal Commission Local Coastal Program Local Assistance Grant. This vulnerability assessment is a technical report that presents key findings from the assessment of exposure, sensitivity, and adaptive capacity of critical built, natural, and cultural assets to coastal hazards.
Pursuant to Assembly Bill No. 691 (AB 691), and as a local trustee of the granted public trust lands, the City completed a state granted lands sea-level rise vulnerability assessment, evaluating the impacts of sea-level rise on its public trust lands and detailing a plan to address vulnerabilities and mitigate impacts. The assessment considers the recommendations under the California Ocean Protection Council’s State Sea Level Rise Policy Guidance and the California Coastal Commission’s Sea Level Rise Policy Guidance to assess impacts of storms and extreme weather events, changing shorelines, trends in relative local sea level, and impacts to public trust resources and values. Through this assessment, the City identified the vulnerabilities of City assets and public trust resources and facilities, considered replacement or repair costs, and assessed the impact to non-market values, such as ecosystem services, for the years 2030, 2050, and 2100. To address these vulnerabilities, the City, with input from local stakeholders, compiled a list of potential adaptation and mitigation measures, organized by climate change hazard. These measures included with estimated costs, associated benefits, and timeframes for implementation.
King Tides, or perigean spring tides, are the higher than normal high tides. These tides can cause coastal flooding and help to demonstrate how sea level rise may affect the coastline in the future. King Tides are natural and predictable, occurring 3-4 times a year when the alignment of the sun and the moon occur during a new or full moon.
To learn more and for information on how to get involved as a citizen scientist and to see photos of the tides along our coastline, check out the California King Tides project.
