CA Water Code Section 31144.76

(a)

Prior to the end of the water year in which the hearing is held, and based upon the findings and determinations at the hearing, the board shall determine whether or not a groundwater charge should be levied in any zone or zones. If the board determines that a groundwater charge should be levied, the board shall levy, assess, and affix the charge or charges against all persons operating water-producing facilities within that zone or zones during the ensuing water year. The charge shall be computed at a fixed and uniform rate per acre-foot for all water other than agricultural water. The rates shall be established each year in accordance with a budget for that year and shall be at a fixed and uniform rate for all water other than agricultural water.

(b)

Any groundwater charge levied pursuant to this article shall be in addition to any general tax or assessment levied within the district or any zone or zones thereof.

(c)

Clerical errors occurring or appearing in the name of any person or in the description of the water-producing facility where the production of water therefrom is otherwise properly charged, or in the making or extension of any charge upon the records which do not affect the substantial rights of the assessee or assessees, shall not invalidate the groundwater charge.
