Exhibit A System Development Charge Methodology Introduction This document serves as the system development charge (SDC) methodology for the Metropolitan Wastewater Management Commission (MWMC) Regional Wastewater System. The MWMC is the regional wastewater treatment agency for the Eugene- Springfield metropolitan area. System development charges may be collected from all development that connects to the Regional Wastewater System, including development that changes the use of existing development, when the change of use results in a greater impact on the system. The methodology contained in this document was developed in accordance with Oregon SDC legislation (ORS 223.297-223.314), and with the guidance of a Citizen Advisory Committee (CAC) appointed by MWMC. Table 1 provides a comparison of key methodological requirements from the Oregon Revised Statute (ORS) to elements of the MWMC methodology.
