Cal. Health and Safety Code § 5473

Any entity which has adopted an ordinance or resolution pursuant to this article or an order pursuant to Section 6520.5 may, by such ordinance or resolution or by separate ordinances or resolutions approved by a two-thirds vote of the members of the legislative body thereof, elect to have such charges collected on the tax roll in the same manner, by the same persons, and at the same time as, together with and not separately from, its general taxes. In such event, it shall cause a written report to be prepared each year and filed with the clerk, which shall contain a description of each parcel of real property receiving such services and facilities and the amount of the charge for each parcel for the year, computed in conformity with the charges prescribed by the ordinance or resolution. Any ordinance or resolution adopted pursuant to this section authorizing the collection of charges on the tax roll shall remain in effect for the time specified in the ordinance or resolution or, if no time is specified in the ordinance or resolution, until repealed or until a change is made in the rates charged by the entity. The powers authorized by this section shall be alternative to all other powers of any entity, and alternative to other procedures adopted by the legislative body thereof for the collection of such charges. The real property may be described by reference to maps prepared in accordance with Section 327 of the Revenue and Taxation Code, and on file in the office of the county assessor or by reference to plats or maps on file in the office of the clerk.
