Climate Risks
San Mateo County faces sea level rise, rising temperatures and heatwaves, wildfires and wildfire smoke, flooding, and landslides due to climate change. While the changing climate poses many risks to the people and places in San Mateo County, together we can take steps to adapt and protect our people and our valuable resources.

Housing and Climate Readiness
The Housing and Climate Readiness Toolkit (PDF) identifies best practices in site design and land use for decision-makers and practitioners. To address San Mateo County’s housing shortage and prepare homes for climate change impacts, practitioners will need to pursue bold actions and closer coordination. This toolkit’s strategies provide examples of options that can be used to tackle these complex challenges and case studies where these strategies have been implemented.
