What is the scope of alternatives in the California Regents' Environmental Assessment Review?

The District contends that the Regents suggested cheap means to resolve the potential problems that implementation of the Plan poses for the District. "CEQA establishes no categorical legal imperative as to the scope of alternatives to be analyzed in an EIR. Each case must be evaluated on its facts, which in turn must be reviewed in light of the statutory purpose." (Citizens of Goleta Valley v. Board of Supervisors, supra, 52 Cal.3d at p. 566, 276 Cal.Rptr. 410, 801 P.2d 1161.) The scope of alternatives discussed in an EIR must be judged against the rule of reason. (Id. at p. 565, 276 Cal.Rptr. 410, 801 P.2d 1161.) The Regents properly set forth a wide range of alternatives to mitigate or avoid potential significant effects on the physical environment. These alternatives include increasing class sizes, instituting year-round schools, adding portable classrooms and building new classrooms, among others.
