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