Throughout the 19th and 20th centuries the board addressed issues linked to infrastructure projects like the construction of the Transcontinental Railroad, regional development shaped by figures such as John Muir and organizations like the Southern Pacific Railroad, and social changes associated with migration waves tied to the Great Migration and wartime industries in Richmond, California. In the late 20th and early 21st centuries the board engaged with environmental regulation under statutes like the Clean Air Act and interacted with agencies such as the California Environmental Protection Agency and U.S. Environmental Protection Agency on matters including land use, hazardous waste at sites overseen by Department of Toxic Substances Control, and responses to disasters like the Loma Prieta earthquake.
The board consists of five supervisors each representing a supervisorial district that includes municipalities such as Concord, California, Richmond, California, Walnut Creek, California, Antioch, California, and unincorporated communities like North Richmond and Pacheco, California, reflecting a districting process influenced by principles in cases such as Reynolds v.
