Wat. Code, § 31104.8

(a) Notwithstanding any other provision of this division, the Santa Ana Mountains County Water District may, pursuant to the notice, protest, and hearing procedures in Section 53753 of the Government Code, fix, in each fiscal year, within Community Facilities District No. 2 of the district, sewage and waste service standby or availability assessments of not more than two hundred fifty dollars ($250) per year for each acre or portion thereof to which sewage and waste service is immediately available, unless the standby or availability assessment is imposed pursuant to the Uniform Standby Charge Procedures Act (Chapter 12.4 (commencing with Section 54984) of Part 1 of Division 2 of Title 5 of the Government Code). The Board of Directors of the Santa Ana Mountains County Water District may establish schedules varying the assessment according to the land uses and the degree of availability or quantity of use of the sewer capacity to the affected lands.

(b) The Santa Ana Mountains County Water District may elect to have the assessments authorized by subdivision (a) for the fiscal year collected on the tax roll in the same manner, by the same persons, and at the same time, as, and together with and not separately from, county taxes. In that event, the district shall prepare a written report which shall be filed with the secretary. The report shall contain a description of each parcel of real property and the amount of the assessment for each parcel for the year.

(c) The sewage and waste service standby or availability assessment authorized by this section shall not be imposed on any subdivided parcel upon which there exists a residential unit which has been connected to domestic sewer facilities of the Santa Ana Mountains County Water District.

(d) If the procedures set forth in this section as it read at the time a standby or availability assessment was established were followed, the Santa Ana Mountains County Water District may, by resolution, continue the charge pursuant to this section in successive years at the same rate. If new, increased, or extended assessments are proposed, the board shall comply with the notice, protest, and hearing procedures in Section 53753 of the Government Code.
