Which of the following is NOT a local agency?

The Air Resources Board is a state agency, which is why it is the correct choice when identifying which option is not a local agency. The Board, which operates under the California Environmental Protection Agency, is responsible for air quality and pollution control issues at the state level. Its main focus is to establish regulations and oversee programs that influence air quality throughout California.

In contrast, the other options listed are typically considered local agencies. Fire Departments operate at various local government levels, addressing fire safety and emergency response needs within their communities. Transportation Departments generally manage local transportation systems, coordinating infrastructure and public transit within specific municipalities. Building and Safety departments enforce local building codes and safety regulations, ensuring that structures meet health and safety standards in their jurisdictions. Each of these agencies operates within specific local contexts, serving the immediate needs of their communities.
