Oakland's Dimond District air quality reflects the East Oakland residential and commercial neighbourhood, with vehicle traffic on MacArthur Boulevard and the surrounding mixed residential and commercial character contributing local sources. The Bay Delta breeze provides afternoon ventilation, while the neighbourhood's walkable character and the East Bay hills create modest topographic variation and Dimond generally maintains moderate Oakland metropolitan readings throughout most of the year.
