California Code, Public Utilities Code - PUC § 170064

(a) From revenues in accounts attributable to airport operations, the port shall fund the authority for not less than one million dollars ($1,000,000) each year until that time as the transfer of the airport and all associated revenue sources have been completed between the port and the authority. The authority's board may submit a budget request for more than this amount if necessary to carry out its duties. The port shall approve those budget requests in a timely manner without modification or reduction. The authority shall report its total budget expenditure amount to the port on an annual basis and balance or carryover reserves from previous budgets. The funding provided by this subdivision replaces any loans made to the authority by the port under the former provisions set forth in this subdivision requiring the port to loan the authority the sum of one million dollars ($1,000,000).

(b) Upon the completion of the transfer of San Diego International Airport to the authority, the authority shall assume all revenue stream revenues to fund its activities, operations, and investments consistent with its purposes. The sources of revenue available to the authority may include, but are not limited to, imposing fees, rents, or other charges for facilities, services, the repayment of bonded indebtedness, and other expenditures consistent with the purposes of the authority.

(c) To the extent practicable, the authority shall endeavor to maximize the revenues generated from enterprises located on the property of the authority.

(d) The authority may receive state and federal grants for purposes of planning, constructing, and operating an airport and for providing ground access to airports under its control.
