A. The impact fee schedule is calculated based upon the formula set forth in Table 4A-1. The formula in Table 4A-1 is the County's determination of the appropriate proportionate share of the costs of public school capital facilities needed to serve new growth and development to be funded by school impact fees.

B. The impact fee schedule, as enacted, includes a Maximum Fee Obligation. The actual fee obligation is the lesser of the Fee Calculation or the Maximum Fee Obligation.

C. Separate fees shall be calculated for single-family and multi-family types of dwelling units, because of their different impact on school facilities. Separate student generation rates (student factor) must be determined by the District for each type of dwelling unit. For purposes of this Title, mobile homes shall be subject to the single-family dwelling unit fee and duplexes and zero lot line homes shall be subject to the multi-family dwelling units fee.

D. Beginning January 1, 2019, and annually thereafter, the Maximum Fee Obligation shall be adjusted according to the change in the Construction Cost Index (20-City Average) published by the Engineering News Record using February 2017 as the base value. Each year, the adjustment shall be brought forth by ordinance in conjunction with adoption of the County Capital Facility Plan and any review of impact fees pursuant to PCC 4A.30.010.

E. The Fee Calculations shall be made on a district-wide basis to assure maximum utilization of all school facilities in the District currently used for instructional purposes.

F. The formula in Table 4A-1 also provides for a credit for school sites or facilities actually provided by a fee payer which are included in a School District Capital Facilities Plan and that are required by the County as a condition of development approval.

G. The Maximum Fee Obligation in this Chapter continues until adjusted by ordinance.
