For purposes of this article and Article 10.5 (commencing with Section 41860), the home-to-school transportation allowance received by the Oakland Unified School District in the 1996–97 fiscal year and each fiscal year thereafter shall be computed as if the home-to-school transportation aid received by the school district in the 1995–96 fiscal year was two million five hundred thousand dollars ($2,500,000). The amounts allocated to the Oakland Unified School District pursuant to this section shall be contingent upon approval of the district’s home-to-school transportation costs and shall not exceed those costs.
