Cal. Ed. Code § 1097
Whenever a tax rate or portion thereof is levied by any county for the support of its county board of education and superintendent of schools, the assessed valuation of all, but only such portions of elementary and unified school districts under its jurisdiction, shall be considered. The tax rate or portion thereof so computed shall be levied uniformly in all such areas, irrespective of the county in which situated. All moneys collected in surrounding counties from the levy of such tax rate or portion thereof shall be remitted by the respective county auditors to the auditor of the county of jurisdiction and shall be deposited by him to the credit of the fund or funds from which the support of his county board of education and superintendent of schools is derived.
This section shall be applicable to a chartered county if Section 1001 is applicable to it.
