Los Angeles County Waterworks District No. 40 v. TapiaAnnotate this Case
The Antelope Valley Groundwater Cases (AVGC) proceeding litigated whether the water supply from natural and imported sources was inadequate to meet the competing annual demands of water producers, thereby creating an overdraft condition. One of the competing parties, Appellant Tapia, individually and as trustee of a trust, claimed that he owned land overlying the aquifer. Settlement discussions ultimately produced an agreement among the vast majority of parties in which they settled their competing groundwater rights claims and agreed to support the contours of a proposed plan designed to bring the Antelope Valley Adjudication Area (AVAA) basin into hydrological balance. Tapia was not among the settling parties. Accordingly, before considering whether to approve the Physical Solution for the AVAA basin, the trial court conducted a separate trial on Tapia's unsettled claims and defenses.
The Court of Appeal concluded that the Physical Solution's allocation of the "native safe yield" (NSY) does not violate California's water priorities; the allocations to correlative rights holders accord with California law; the Physical Solution's allocation of the NSY does not violate California's principles promoting the reasonable and beneficial use of water; and substantial evidence supports the judgment as to Tapia, and the Physical Solution is consistent with California law governing water priorities and the constitutional reasonable and beneficial use requirement.
