If the average value of the secured roll of a community college district which is attributable to timber over the period of fiscal years 1972-73 to 1974-75, inclusive, meets or exceeds 20 percent, then the auditor shall use a rate which when multiplied by that district's average annual assessed value attributable to timber will produce an amount equivalent to the total amount of property taxes raised by that district in the 1976-77 fiscal year.
For purposes of this section, "average annual property tax revenue attributable to timber" of each school district which levied an areawide tax rate in one or more of fiscal years 1972-73 to 1974-75, inclusive, shall be the product of (1) the amount of money the district received as its reallocation from the areawide fund (not the amount of its own contribution raised from its actual areawide tax rate) for each such fiscal year, and (2) a factor produced by the amount of annual assessed value attributable to timber divided by the amount of all assessed value, within the school district, for each such fiscal year.
Each county auditor shall certify to the Controller a list of this amount for each taxing agency in the county and the total of all such amounts for the county. The auditor shall keep such records for each tax rate area as necessary to make distribution of funds pursuant to Section 38906 of the Revenue and Taxation Code.
For purposes of this subdivision, the average annual property tax revenue attributable to timber for a taxing agency formed subsequent to June 30, 1975, shall be calculated as follows:
For purposes of this subdivision, the average annual property tax revenue attributable to timber for a taxing agency formed prior to June 30, 1975, which annexes territory subsequent to that date, shall have added to it the sum of the values of the tax rate areas, as determined by the assessor or the board pursuant to subdivision (a) which corresponds to the territory which was annexed, multiplied by the average total tax rate levied during fiscal years 1972-73 to 1974-75, inclusive, by the taxing agency which annexed the territory.
For purposes of this subdivision, the average annual property tax revenue attributable to timber for a taxing agency which subsequent to June 30, 1975, has transferred to it by functional consolidation the responsibility of levying a property tax rate to pay the cost of a new service or program shall have added to it the sum of the average annual assessed value attributable to timber for that agency multiplied by the additional property tax rate to be incurred in the first year pursuant to the functional consolidation. For a taxing agency which subsequent to June 30, 1975, has transferred from it the responsibility of levying a property tax rate for a service or program, the average annual property tax revenue attributable to timber shall be reduced by the sum of the annual assessed value attributable to timber for that agency multiplied by the average tax rate levied by the taxing agency during fiscal years 1972-73 to 1974-75, inclusive, for the support of such service or program.
For purposes of this subdivision, when an additional property tax rate is approved by the voters of a taxing agency in the preceding fiscal year, such agency shall have its average annual property tax revenue attributable to timber revised in the same manner as for a functional consolidation in which responsibility for the funding of a new service or program is added; provided, that such revision will extend only for the same period of time as that authorized by the voters for the existence of the additional voted property tax rate.
