California Code, Streets and Highways Code - SHC § 31866.5

As a condition to the granting of a petition for inclusion under Section 31866, the legislative body, with the approval of the board of parking place commissioners, may require that the owner pay to the city an amount in addition to the amount required by and computed under Section 31866, which additional amount shall not exceed an amount deemed by the legislative body to be reasonable in light of the elapse of time and changes in circumstances since the levy of prior assessments and special ad valorem tax levies. Such additional amount shall be placed in such fund as the board directs and may be used for the purposes specified in Section 31866.
