The Tri-Valley region-including San Ramon, Dublin, Pleasanton, and Livermore is located in eastern Alameda County within the Bay Area Air Quality Management District. Home to over 310,000 residents, the area is diverse, with generally higher education and income levels, though some lower-income communities exist. Air pollution from freeway traffic, local industry, and wildfire smoke poses health risks such as asthma and increased cancer rates. 

The district has teamed up with Aclima and the California Air Resources Board (CARB) to launch a community air monitoring project guiding 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, residents and stakeholders gathered to discuss these air quality concerns and explore solutions to improve community health and resilience.
