Santa Rosa, located in Sonoma County and part of the Bay Area Air Quality Management District, is home to 175,845 residents and a vibrant Hispanic community, especially in the Roseland area. While Santa Rosa generally enjoys good air quality, neighborhoods in Southwest Santa Rosa face higher pollution burdens due to proximity to highways, the airport, and industry, resulting in elevated rates of asthma and heat-related illness.

The city has teamed up with Aclima and the California Air Resources Board (CARB) to launch a community air monitoring project to guide future actions as a part of SMMI. Using Aclima’s advanced sensors, the project collects detailed, block-by-block data on air quality throughout the community. This provides residents with clear information about local pollution and helps guide actions to improve air quality, focusing on the areas and people most affected.  

In April of 2025, community members and stakeholders met to discuss these air quality challenges and explore solutions for a healthier future.
