Changing climate conditions such as higher temperatures, more intense periods of rainfall, and sea level rise are expected to make life more difficult in California's cities. In response, the state encourages local planning processes to consider climate change adaptation and resilience.
To help understand what specific risks climate change poses to San Leandro, the City conducted a Climate Hazards Assessment and presented to the City Council on July 17, 2017. The full document is available here.
The biggest threats to San Leandro are sea level rise, high tides, and flooding to the west. Temperature increases and more frequent very hot days will likely affect the entire city. Hotter days are dangerous anywhere, but high temperatures can be especially harmful in urban settings because there are fewer trees and green spaces, and paved surfaces absorb and re-radiate heat.
