In applying this subdivision, the base year value of the subject real property does not include that portion of the previous base year value of that property that was attributable to any portion of the property that has been destroyed or removed. The sum determined under this subdivision shall then become the base year value of the real property until that property is restored, repaired, or reconstructed or other provisions of law require establishment of a new base year value.
However, for each lien date after the first lien date for which the taxable value of property is reduced pursuant to paragraph (2) of subdivision (a), the value of that property shall be annually reappraised at its full cash value as defined in Section 110 until that value exceeds the value determined pursuant to paragraph (1) of subdivision (a). In no event shall the assessor condition the implementation of the preceding sentence in any year upon the filing of an assessment appeal.
