FGC § 10682

If in any year, on lands hereafter acquired, the in lieu payments from the United States to the county, pursuant to the provisions of law, do not equal the taxes assessed on a given project, the department shall pay from income derived from hunting privileges on the project an amount equal to the balance of the taxes on the entire project.

For the purposes of this section, the taxes on a given project are the assessed taxes on the project at the time of acquisition, plus any subsequent increases that may accrue from general county increases in the tax rates, but not subject to re-evaluation of such project properties after the time of acquisition.
