Residential Dwelling Unit (RDU): Residential Dwelling Units are used in the calculation of wastewater SDCs as a basis for determining the relative impact or service used by residential development. A base fee is applied to each RDU, such as one house, one accessory dwelling unit, or each apartment unit, plus a rate per square foot is applied to the total living area. For manufactured home parks, which are charged SDCs at the time a park's initial development permit is issued, the local wastewater SDC will be based upon the maximum size of manufactured home that can be placed on building pads located within the park. Each space shall constitute an RDU and the rate per square foot shall be applied to the total gross floor area of all additional proposed structures within the park. SDC Eligible Costs: System value net of assessable costs, grants and outstanding debt. This cost is allocated to all development in proportion to its impact on system capacity. SS: Suspended Solids. The total elements and compounds which float on the surface of, or are suspended in, wastewater and which are removable by laboratory filtration, expressed in milligrams per liter. Secondary Dwelling Unit (SDU): See Accessory Dwelling Unit. Single Family Dwelling (SFD): As used in EC 7.725(b) and this methodology, a "single family dwelling" means a "Dwelling, single family detached" as defined in EC9.015. TGSF: Thousand Gross Square Feet. Sum (expressed in the thousands, in decimal form) of the area of each floor level, including, but not limited to, basements, mezzanines, penthouses, corridors, mechanical rooms, and storage areas that are within the principal outside faces of the exterior walls. The City's TGSF definition is based upon the definition of "gross floor area" in the Institute of Traffic Engineer's Trip Generation Manual. TGSF measurements: • Include exteriorwalls • Include all areas that have clear standing headroom (6 feet, 6 inches minimum), regardless of their use • Shall count the area of stairs once for each two floors the stairs connect • Shall count the shaft of an elevator once, regardless of the number of stories it connects • Do not include parking and drive aisle areas within parking garages TGSFLA: Thousand Gross Square Foot Leasable Area Transportation Demand Management (TDM): A transportation planning proposal for a given development that reduces the demand that development places upon the transportation system by redistributing or eliminating vehicle trips and encouraging the use of alternate modes of travel. Unit of Development (Unit): Unit of measure for determining the size of a development for use in calculating the effect of the development on a system. • Example: Number of Units of Development x Impact Measure per Unit = Impact of Development Page A-5 City of Eugene SDC Methodologies, Appendix A
