A. The methodology used to establish a reimbursement fee shall consider the cost of then-existing facilities, prior contributions by then-existing users, the value of unused capacity, rate-making principles employed to finance publicly owned capital improvements, and other relevant factors. The methodology shall promote the objective that future systems’ users shall contribute an equitable share of the cost of then existing facilities.

B. The methodology used to establish the public improvement charge shall consider the cost of projected capital improvements needed to increase the capacity of the systems to which the fee is related and shall provide for credit against the public improvement charge for the construction of any qualified public improvement.

C. The methodology may also provide for a credit as authorized in MMC 3.10.070.

D. Except when authorized in the methodology adopted under subsection A of this section, the fees which are assessed or collected as part of a local improvement district or a charge in lieu of a local improvement district assessment, or the cost of complying with requirements or conditions imposed by a land use decision are separate from and in addition to the systems development charge and shall not be used as a credit against such charge.

E. The methodologies used to establish the systems development charge shall be adopted by resolution of council. The specific systems development charge may be adopted and amended concurrent with the establishment or revision of the systems development charge methodology. The city manager shall review the methodologies established under this section periodically and shall recommend amendments, if and as needed, to the council for its action.

F. The formulas and calculations used to compute specific SDCs are based upon averages and typical conditions. Whenever the impact of the individual developments present special or unique situations such that the calculated fee is substantially disproportionate to the actual impact of the development, alternative fee calculations may be approved or required by the city manager under prescribed administrative procedures. All data submitted to support alternate calculations under this provision shall be specific to the site and development under consideration. Major or unique developments may require special analyses to determine alternatives to the standard methodology. (Ord. 4980 §1, 2014; Ord. 4495 §1 (part), 1991).
