Morgan Hill, located in southern Santa Clara County within the Bay Area Air Quality Management District, is home to about 45,000 residents with many Spanish-speaking and immigrant families.

Pollution concerns in Morgan Hill stem from Highway 101 traffic, construction, nearby agricultural activities, and increasingly frequent wildfire smoke events. These sources contribute to elevated rates of asthma, cardiovascular disease, and low birth weight, disproportionately affecting Latino and low-income neighborhoods. 

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, Morgan Hill residents and stakeholders met to discuss these pressing air quality challenges and explore equitable solutions for a healthier community.
