The innp8S[ analysis for the S1Ornnvvater system is based on square footage of impervious surfaCe, which cvaabsa an impact On the atonnvv@ter avotenO by land use type. Impervious surface is defined in section 6.400 Eugene code, 1971 as "any hard surface area which Causes water to run off the surface in greater quantities or at an increased rate of flow from conditions pre-existing to development. Common impervious surfaces include, but are not limited to, rooftops, vva|kmxays, driveways, parking |ote, or concrete or asphalt surfaces." The estimated non-assessable cost of the system-wide capacity from future capacity-enhancing projects, as contained in the Gtorrnvvater SDC-Eligible Project List and the estimated available capacity in the existing mtornnvvateroys1ern projected to be used by new development is used as the basis for determining the etmrrnvvoter 8[)C. The stornnvvate[ SOC is comprised of an improvement fee and 8 reimbursement fee, as new development will require the construction of additional system umpBcih/ as well as the use of available oepaoih/ in the existing system. The per unit cost of additional capacity for the improvement fee is based on the value of the system-wide capacity of future capacit enhancing projects (current planned projects are listed in the 8tornnvvatgr SOC-Eligible Project List, Table divided by the total projected impervious surface area that will be added by new development at build-out within the Urban Growth Boundary (UGB). The per unit cost of existing capacity for the reimbursement fee is based on the value of available system-wide capacity within the existing system projected to be used by new development divided by the total projected impervious surface area that will be added by new development at build-out within the UGB. storrnwater Construct site LJE) facHrfies to treat Mi required �inip,2rvious suir"face rUrlOff, Dev,e n,,�,,e_, ai The value of the future etmrnnvv@ter system is based on the estimated Costa of planned future capacity-enhancing s[Vrmnvvaier projects contained within atornnvv@t8r plans and the {|8piƒa| Improvement Plan (C|P). Of that total value, the SDC-eligible component is attributable to those portions of future projects that are non-assessable and capacit and related to the demands of future development; i.e. add new capacity for new users. The total value of the existing system is estimated based DO the replacement cost of the stornOvvater system components, which include both piped system and open channel system components. Assessable costs are excluded from the 8[}C-eligible existing system costs. Assessable costs are determined using the approach specified in the Qb/ Code. The city assesses Up to and including the first 24 inches of pipe diameter or equivalent capacity. The
