FIGURE 4-SDC SCHEDULE DEVELOPMENT Using industry reference da,ta for charging SDCs is consistent with the approach MWMC has previously used to charge,SDCs. This type of approach uses flow and strength assumptions that are consistent with the system capacity parameters described previously. For example, average flow is defined as dry season maximum month flow. This capacity measure is used in estimating user capacity requirements. The peak-to-average flow ratio reflects the system planning assumptions. The flow and ~trength aS$umptions for various land uses (development types) are presented in, Appendix D. If information for a particular development is not found in Appendix D, the SDC will be formulated using average data of like or similar development as determined by the City Engineer. Unit Costs x x x x Capacity Requirement / SDC/Unit - - Methodology Element Four: Calculate Revenue Offsets and Credits To comply with Oregon SDC law, the SDC methodology must ensure that future system users contribute no more than an 1/ equitable share" of the capital costs of existing facilities. Before real property is developed, it may have been subject to taxes that supported capital funding of some of the Regional Wastewater System. After a development ~onnects to the system, it will pay rates and, possibly taxes as well, tha't may also support some level of capital funding. The SDC methodology therefore considers past and future payments to be made by new developments, which may partially fund the same facilities for which the SOCS were paid. Past Payments A portion of MWMC's existing facility costs were funded through general obligation (GO) bonds. The debt service on the bonds was retired through property taxes. Undeveloped land in the cities of Eugene and Springfield was' subject to property taxes, and therefor~a GO bond credit is included in the methodology. The credit is equal to the present value of past payments on bond principat expressed in dollars per $1,000 of assessed valuation. The credit shall accrue from the year of annexation, and be b~sed upon the assessed value of the real property at the time of application for connection to the system.
