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 />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: used as an impact measure for the stormwater SDC. An impervious surface <br />is that which prevents or retards saturation of water into the surface of the soil or causes water to <br />run off the surface in greater quantity or an increased rate of flow compared to the natural condition <br />of the property before development. Asphalt, concrete, and roofing materials are examples of <br />impervious materials. <br />Improvement Fee: the portion of the system-specific SDC charged to cover an equitable share of <br />the capital improvements required to increase capacity of the system to accommodate new <br />development. <br />Level of Service: (per unit of development) - as used in development of SDC rates, represents the <br />amount of system (orsub-system) capacity provided at a certain point in time. The current level of <br />service is used as the basis for determining the system impacts of new development. This is <br />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 />Physical Improvements (for impact reduction/mitigation): A facility or asset, designed and <br />constructed at the developer's expense, which is owned and maintained by the property owner or <br />owner's agent; not a program or activity or naturally occurring physical attribute. <br />.Proportionate Share of Public Facility Costs: the cost of capital improvements which are <br />reasonably attributable to new development. <br />PFtJ: Plumbing Fixture Units -defined in the state Uniform Plumbing Code. A rating assigned to <br />different drainage fixtures depending on drain pipe or fixture size. <br />Reimbursement Fee: the portion of the system-specific SDC charged to recoup the community's <br />past or cun°ent investment in extra capacity in anticipation of future growth. An example is the facility <br />equalization charge established by MWMC to recoup the regional investment in extra capacity made <br />for the wastewater treatment facility. <br />Replacement Costs: the cost (in current fiscal year dollars) of replacing existing system capacity. <br />SDC Eligible Costs: system value net of assessable costs, grants and outstanding debt. This cost <br />is allocated to all development in proportion to its impact on system capacity. <br />Single Family Dwelling (SFD): as used in EC 7.725(b) and this methodology, a "single family <br />dwelling" means a "Dwelling, single family detached" as defined in EC 9.015. <br />May 1, 1997 City of Eugene SDC Methodology Page B-2 <br />
