Air Quality

Post Date:10/24/2019 4:46 PM

Walnut Creek is taking actions to improve air and water quality to reduce negative impacts on our health and wellness.


As a large urban area, our potential for air pollution is relatively high. The city is particularly prone to high ozone levels in the summer, when ozone and its precursors drift into Walnut Creek from the more densely urbanized parts of the Bay Area. 


Although federal and state laws establish regulations for major sources of pollution, air quality is regulated at a regional level – with a primary focus on reducing emissions. Walnut Creek recognizes the bottom-up nature of pollution – that the cumulative results of transportation and land use policies can assist or negate regional air quality planning and accomplishments. To learn more about our action on air quality, review our Climate Action Plan here.


The city’s goals to protect air quality include:

  • Strive to meet state and federal air-quality standards for the region.

  • Work with the Bay Area Air Quality Management District (BAAQMD) and the county in promoting better air quality.

  • Participate in the BAAQMD Spare the Air program.
