California Code, Government Code - GOV § 70358

Insurance costs shall be included in the county facilities payment.  If the actual expenditures made by the county are used to determine the amount, the expenditures shall be based on the 1999-2000 fiscal year multiplied by the increase in the inflation index specified in Section 70355 from January 2000, to the month of the date of the transfer of responsibility for the court facilities from the county to the state, inclusive.

The amount of insurance may not include the cost of any insurance required by any agreement involving bonded indebtedness on the facility to the extent that the cost of insurance is greater than the cost of commercial insurance coverage on the building.

The determination of the insurance costs may consider the costs of commercial insurance coverage for a fair and reasonable level of insurance and the costs of self-insurance.  The amount of the insurance costs shall be subject to negotiation between the Judicial Council and the county.

To the extent the responsibility for grounds is transferred, the insurance costs for court facilities shall include, but not be limited to, the cost of liability insurance relating to the grounds.
