Appendix 1

Appendix 1 consists of fees adopted by the Board of Supervisors through the public hearing process and incorporates Ordinance No. 776 (effective 8/17/1990), Ordinance No. 784 (certain portions effective 12/28/1990 and the remainder effective 1/1/1991), and Ordinance No. 808 (effective 10/1/1991).

Ordinance No. 939 rescinded Ordinance No. 808 on 12/1/1998 after State legislation was passed which amended the statute permitting fees to be adopted by resolution instead of by ordinance. Following the adoption of the Mariposa County Master Fee Resolution (Resolution No. 92-524), approved by the Board of Supervisors on October 6, 1992, fees are no longer adopted by ordinance.
