Attachment #6 of Exhibit A <br />Administrative Order No. 58-97-07 <br />Page2of3 <br />Cost of Service: The calculation of a "per unit" cost to the City of providing system-specific capacity <br />(e.g., wastewater collection capacity). <br />Development Types: As used in determining SDC rates, development is categorized depending on <br />the relative impact. Primarily a factor in the Transportation SDC where development is charged <br />according to the different trip rates assigned to development types, and in the Metropolifari <br />Wastewater Management Commission SDG, where development is charged according to he <br />different rates per FEU assigned to development types. <br />EDU: Equivalent Dwelling Unit. EDU is used in the wastewater SDC as a basis for determining the <br />relative impact or service used by different types of development. Represents the use of capacity <br />that is approximately equal to that of a single dwelling unit. For the purposes of setting the City of <br />Eugene Wastewater SDC, an equivalent dwelling unit is equal to 16 plumbing fixture units as defined <br />in the State Uniform Plumbing code. <br />Equitable Share of Public Facility Costs: As used in the development of SDCs, the City's cost of <br />providing system capacity, allocated to new development relative to the development's impact or use <br />of system capacity. <br />FEU: Flow Estimation Unit. For the;lVletropolitan Uastewater Management:Cornrnission SDC,`fhe <br />Flow Estimation Unit is the unit of impact upon which the rate per unit is based. The FEU is typically <br />1,000 square feet of building area ,for most commercial users, and dwelling units; for tesidentia! <br />developmert: <br />Impact Measurement: The unit of system capacity used to determine the relative effect of a new <br />development on the capacity of a specific system. For example, plumbing fixture units are used to <br />determine the effect of development on -the wastewater system. <br />Impervious Surface: lrnpervious surface is used as an impact measure for the stormwater SDC. <br />An impervious surface is that which prevents or retards saturation of water into the surface of the <br />soil or causes water to run off the surface in greater quantity or an increased rate of flow compared <br />to the natural condition of the property before development. Asphalt, concrete, and roofing materials <br />are examples of impervious materials. <br />Improvement Fee: The portion of the system-specific SDC charged to cover an equitable share <br />of the capital improvements required to increase capacity of the system to accommodate new <br />development. <br />Level of Service (LOS): (per unit of development) As used in development of SDC rates, LC?S <br />represents the amount of system (or sub-system) capacity provided at a certain point in time. The <br />current level of service is used as the basis for determining the system impacts of new development. <br />This is presented in terms of the appropriate impact measure. <br />Methodology: This document entitled "METHODOLOGIES: City of Eugene, Systems Development <br />Charges" and any amendment or modification made hereto. <br />MWMC: Metropolitan Wastewater Management Commission -responsible for regional wastewater <br />treatment. <br />Proposed: July 7, 1997 City of Eugene SDC Methodology Page B-2 <br />
