Pub. Resources Code, § 5364

The legislative body of the city shall, at the time of fixing the general tax levy, and in the manner for the general tax levy, levy and collect a tax each year upon the taxable land in the district sufficient to pay the interest on the bonds for that year, and such portion of the principal as is to become due before the time for making the next general tax levy; provided, however, that if the maturity of the indebtedness created by the issue of such bonds be made to begin more than one year after the date of issue, such tax shall be levied and collected, each year sufficient to pay the interest on the indebtedness as it falls due, and also to constitute a sinking fund for the payment of the principal on or before maturity. The tax shall be in addition to all other taxes levied for municipal purposes and when collected shall be paid into the treasury of the city and be used for the payment of the principal and interest on such bonds and for no other purpose.

The legislative body may provide, in the resolution or ordinance calling the election, that the tax to pay principal and interest on the bonds provided for in this section shall be levied and collected upon all taxable property in the district rather than on taxable land. If the proposition submitted pursuant to such resolution or ordinance is approved as provided in Section 5359, the tax shall be levied as provided in such ordinance or resolution.
