Cal. Public Resources Code § 5539.7

(a) In addition to the authority conferred in Section 5539.5, all provisions of the Landscaping and Lighting Act of 1972 (Division 15 (commencing with Section 22500) of the Streets and Highways Code) are applicable to a district if created and established in Riverside County. (b) Notwithstanding any provision of the acts listed in Section 5539.5 and in this section, no assessment shall be levied on real property in the district created and established in Riverside County unless and until it is approved by a majority of the electors of the district. An election called for this purpose may be consolidated with the election for the creation and establishment of the district. (c) The particular amount of the proposed assessment, or a range within which the governing body may fix the amount of the assessment and thereafter revise it during a specified period of time, shall be specified in the measure submitted to the electors pursuant to subdivision (b). In addition, the measure may contain a provision obligating the district, if created and established in Riverside County, to issue to any person paying the assessment an annual pass or coupons entitling that person to the free use, or use on a reduced-fee basis, of district facilities, of a value not to exceed the amount paid by the person as an assessment.
