CSAC is seeking depublication of this opinion out of the Fourth Appellate District, which held that a tiered water rate, even if designed to address water conservation, is unconstitutional if it is unsupported by an actual cost of service calculation for each tier.  CSAC’s depublication request, filed jointly with the League of California Cities and the Association of California Water Agencies, argues that the opinion fails to harmonize the constitutional duty to conserve water with the tax and fee restrictions in Proposition 218, and misconstrues the definition of “water service.”
