Notwithstanding Sections 31031 and 31032.1, in any improvement district situated within the Joshua Basin Water District, the water standby or availability charge or assessment shall not exceed thirty dollars ($30) per acre per year for land on which the charge or assessment is levied or thirty dollars ($30) per year for a parcel less than one acre. In any such improvement district, the proceeds from any water standby or availability charge or assessment in excess of ten dollars ($10) per acre per year or ten dollars ($10) per year for a parcel less than one acre shall only be used for the purposes of the improvement district.
This section, applicable only to the Joshua Basin Water District, is necessary because of the unique and special water management and financing problems of the area included within the district.
