Phelan Piñon Hills Community Services District v. California Water Service Co.Annotate this Case
The Antelope Valley Groundwater Cases (AVGC) proceeding litigated whether the water supply from natural and imported sources, which replenishes an alluvial basin from which numerous parties pumped water, was inadequate to meet the competing annual demands of those water producers, thereby creating an "overdraft" condition. Phelan ultimately became involved in the litigation as one of the thousands of entities and people who asserted they were entitled to draw water from the aquifer.
The trial court subsequently defined the boundaries for the AVAA to determine which parties would be necessary parties to any global adjudication of water rights, and then determined that the aquifer encompassed within the AVAA boundaries (the AVAA basin) had sufficient hydrologic interconnectivity and conductivity to be defined as a single aquifer for purposes of adjudicating the competing groundwater rights claims. Settlement discussions ultimately produced an agreement among the vast majority of parties in which they settled their respective
groundwater rights claims and agreed to support the contours of a proposed plan (the Physical Solution) designed to bring the AVAA basin into hydrological balance. Phelan, which provides water to its customers who are located outside the AVAA boundaries, became subject to the AVGC litigation because a significant source of its water is pumping from a well located in the AVAA basin.
The Court of Appeal held that substantial evidence supports the judgment as to Phelan and Phelan was not deprived of its due process rights to present its claims. In this case, substantial evidence supports the conclusion that Physical Solution will bring the AVAA basin into balance; the trial court correctly rejected Phelan's fourth cause of action asserting it had acquired water rights as a "public use appropriator;" the phased decisional procedure did not deprive Phelan of due process; and the trial court correctly concluded that Phelan had no priority claim to return flows from native safe yield.
