13.55.030 Methodology.
A. Methodology for determining storm water SDCs is based on a fair allocation of the capital costs of storm water system facility improvements upon development that creates the need for, or increases the demand for, such capital improvements. The determination of improvement fees is based on the following:
1. The development of a five-year capital improvement plan (CIP) that identifies storm drainage projects to be constructed over a period of five years. A tabulation of the projects’ current costs and the percentage of costs allocated to new users shall be identified.
2. The equivalent dwelling units are the basis to allocate use of the storm water system and therefore provide the basis for the proportional allocation of the improvements costs for needed storm water system capital improvements.
3. The unit cost of new capacity per equivalent dwelling unit is calculated by dividing the additional capacity in EDUs into the CIP value allocated to new users to determine the unit cost of new capacity per equivalent dwelling units.
B. The determination of reimbursement fees is based on the following:
1. The establishment of unused capacity in the existing storm water system and its associated cost/value.
2. The equivalent dwelling units are the basis to allocate use of the storm water system and therefore provides the basis for the proportional allocation of the improvements costs for needed storm water system capital improvements.
3. The unit cost of existing unused capacity per equivalent dwelling unit is calculated by dividing the unused capacity in EDUs into the cost/value of unused system capacity available to serve new users to determine the unit cost of new capacity per equivalent dwelling unit.
