The local wastewater SDC for a proposed development is determined by: • Number of Residential Dwelling Units (RDU) and area of living space for single-family, duplex, multiple-family, and other residential development • Plumbing Fixture Units (PFU) and proposed development type for other than Residential dwelling units (e.g., Commercial, Industrial) 4.2 Regional Metropolitan Wastewater Management Commission (MWMC) Wastewater System . The City of Eugene entered into an Intergovernmental Agreement with the City of Springfield and Lane County in 1978 which established the Metropolitan Wastewater Management Commission. On May 15, 1997, the Commission adopted the MWMC wastewater Systems Development Charge which includes a regional administrative charge. In accordance with the agreement, the City of Eugene must adopt rates and charges not less than those required by the Commission. The MWMC wastewater SDC formula is based on the allocation of costs of existing or planned capacity to Average Flow, Peak Flow, Biochemical Oxygen Demand (BOD) and Suspended Solids (SS) components of the regional facilities. These cost allocations are used to derive a cost per Flow Estimation Unit (FEU), for each type of land use. The regional wastewater SDC is determined by multiplying the applicable FEU rate per unit of measure for a specific land use type, by the units of measure for the proposed development. The regional wastewater system Cost of Service formula per unit of development can be found in Appendix C. The regional (MWMC) wastewater SDC rates can be found in the current adopted fee schedule in Appendix F. The MWMC wastewater SDC Methodology provides that a review of the Capital Improvement Plan (CIP) will be initiated at such time as any single development with an anticipated discharge of 100,000 gallons per day or more applies for a building permit or for connection to the system. The purpose of this review is to determine if the demand placed on the regional system by that new user will require a change in the timing of future capital projects that will impact the amount of the regional wastewater SDC. If this occurs, the improvement fee portion of the charge will be modified to reflect the value of the new schedule of capacity increasing improvements, and the modified fee will be applied to the development that caused the need for the modification and to all future development. 5.0 stormwater System The stormwater SDC is based upon the square footage of all impervious surface (e.g., rooftops, driveways, sidewalks, parking lots, patios, and other non-porous surfaces). The detailed formula for calculating the stormwater SDC cost per square foot of impervious surface is set forth in Appendix D. The stormwater SDC is determined by multiplying the applicable rate by the unit of measure, for the proposed development type. The stormwater SDC rates per unit of measure can be found in the current adopted fee schedule in Appendix F. Where the stormwater SDC is a fixed amount per dwelling unit or space, it shall be determined by multiplying the amount per dwelling unit or space times the number of units or spaces plus, for manufactured home development, the amount for other features based upon the impervious area times the rate for square footage. Where the stormwater SDC is not a fixed amount per dwelling unit or space, it shall be determined by multiplying the rate per square foot of impervious area times the impervious area of the proposed development. Where a development creates impact not attributable to impervious surface area, the stormwater SDC shall be determined by evaluating equivalent City of Eugene SDC Methodology Page 8
