The San Diego County Board of Supervisors is required to comply with the Levine Act. The purpose of the Levine Act is to prevent public officials, including members of boards or commissions or heads of agencies, from being influenced by campaign contributions from individuals and parties appearing before them and to prevent officials from using their position of authority to unduly influence applicants to make contributions to campaigns.

The Levine Act only applies to certain matters brought to the Board of Supervisors, including permits, licenses, contracts, and other entitlements for use. While these matters are pending and for 12 months after a decision has been made, a Supervisor may not accept, solicit, or direct campaign contributions of more than $250 from parties, participants who have a financial interest in the proceedings, or their respective agents.
