Cal. Revenue and Taxation Code § 195.71

In the 1993–94 fiscal year, or as soon as possible thereafter, the county auditor of an eligible county, proclaimed by the Governor to be in a state of disaster as a result of earthquake, aftershock, or any other related casualty that occurred in the Counties of Los Angeles, Orange, and Ventura, on or after January 17 in 1994, shall certify to the Director of Finance an estimate of the total amount of the reduction in property tax revenues on both the regular secured roll and the supplemental roll for that fiscal year resulting from the reassessment of eligible properties by the county assessor pursuant to Section 170, except that the amount certified shall not include any estimated property tax revenue reductions to school districts (other than basic state aid school districts) and county offices of education. For purposes of this section, “basic state aid school district” means any school district that does not receive a state apportionment pursuant to subdivision (h) of Section 42238 of the Education Code, but receives from the state only a basic apportionment pursuant to Section 6 of Article IX of the California Constitution.
