(a) By September 30, 2005, the auditors of the Counties of Orange, Riverside, San Bernardino, and San Diego, which counties were the subject of the Governor’s proclamations of a state of emergency for the severe rainstorms that occurred in December 2004, January 2005, February 2005, or March 2005, that caused flash floods, mudslides, the accumulation of debris, and that washed out and damaged roads in those counties, 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 the 2004-05 fiscal year resulting from the reassessment by the county assessor pursuant to paragraph (1) of subdivision (a) of Section 170 of those properties that are eligible properties as a result of that disaster, 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. (b) 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.
