California Code, Government Code - GOV § 53226.3

The legislative body of a district, other than a school district, may, by resolution, insure against losses caused by an employee or officer of the district in lieu of providing a bond or bonds. After the resolution is adopted, any requirements of law regarding faithful performance or revolving fund bonds shall be inapplicable to the district or any officer or employee of the district. The amount of the insurance shall be determined pursuant to Sections 1480 and 1481 and shall give the same or greater protection to the district that a bond would provide in indemnifying the district against any loss caused by the employee or officer of the district.
