Cost of Service: The calculation of a "per unit" cost to the City of providing system-specific <br />capacity (e.g., wastewater collection capacity). <br />Development Types: As used in determining SDC rates, development is categorized depending <br />on 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 Metropolitan <br />Wastewater Management Commission SDC, where development is charged according to the <br />different rates per FEU assigned to development types.. <br />EDU: Equivalent Dwelling Unit: EDU is used in the parks SDCs 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. <br />Equitable Share of Public Facility Costs: As used in the development of SDCs, the City's cost <br />of providing system capacity, allocated to new development relative to the development's impact <br />or use of system capacity. <br />FEU: Flow Estimation Unit. For the Metropolitan Wastewater Management Commission SDC, the <br />Flow Estimation Unit is the unit of impact upon which the rate per unit is based. The FEU is <br />typically 1,000 square feet of building area for most commercial users, and dwelling units for <br />residential development. <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 <br />to determine the effect of development on the wastewater system. <br />Impervious Surface: Impervious 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 <br />materials 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, LOS <br />.represents the amount of system (orsub-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 <br />development. This is presented in terms of the appropriate impact measure. <br />Living Area: As used in the determination of SDC rates, living area is defined as the gross floor <br />area, to the outside perimeter, of a dwelling including floor area within structures accessory to the <br />dwellings that is intended for habitation, e.g. bonus rooms over garages, some attic spaces. <br />Methodology: This document entitled "METHODOLOGIES: City of Eugene, Systems <br />Development Charges" and any amendment or modification made hereto. <br />;' ';_ MWMC: Metropolitan Wastewater Management Commission -responsible for regional wastewater <br />treatment. <br />City of Eugene SDC Methodology Definitions, Page A-2 <br />
