A 2002 appellate court decision that subjected a proposed water treatment plant to local zoning and building ordinances appears to be on shaky ground. The state Supreme Court had accepted for review the Sixth District Court of Appeal's ruling in Topsail Court Homeowners Association v. County of Santa Cruz (see CP&DR Legal Digest, April 2002). However, in late March, the state Supreme Court transferred the case back to the Sixth District, directing the appellate panel to reconsider the case in light of legislation approved last year. That legislation, SB 1711 (Costa), was written in direct response to the Sixth District's ruling in Topsail. The Sixth District had declined to exempt a proposed water treatment plant from local land use ordinances because the exemption in the Government Code specified only "facilities for the production, generation, storage or transmission of water" — and did not specify the treatment of water. The decision came in a case in which a small group of residents was trying to block the Soquel Creek Water District from buying a parcel in their subdivision and building a water treatment plant. The ruling "has thrown existing understanding of the law into turmoil," according to a state Senate bill analysis. The state Supreme Court voted unanimously to send the case back to the Sixth District with directions to reconsider — a small step short of ordering the lower court to abandon its earlier decision. The case is Topsail Court Homeowners Association v. County of Santa Cruz, state Supreme Court No. S104952, Sixth District Court of Appeal No. H022122.
