Cal. Sts. & Hy. Code § 2333
In each annual proposed budget prepared pursuant to Section 165, there shall be included an amount equal to the estimated apportionment available from the federal government for the programs described in Sections 2331 and 2333.5. The commission may allocate a portion of those funds each year for use on city streets and county roads. It is the intent of the Legislature that the commission allocate the total funds received from the federal government under Section 148 of Title 23 of the United States Code in approximately equal amounts between state highways and local roads. Notwithstanding any other provision of law, the share of any railroad of the cost of maintaining railroad crossing protection facilities funded, in whole or in part, by funds described in Section 2331 shall be the same share it would be if no federal funds were involved and the crossing protection facilities were funded pursuant to an order of the Public Utilities Commission pursuant to Section 1202 of the Public Utilities Code; and in case of dispute, the Public Utilities Commission shall determine that share pursuant to this section.
