The <br /> r~ltant SDC rate structure applies a charge for every residential dwelling unit (be it a <br /> single-family home, asingle-family accessory unit, each space of a mobile home park, <br /> each unit of a duplex, or each unit of an apartment complex) a base rate of $258 plus the <br /> total living area in square feet multiplied by a factor of $0.062. Additions to residential <br /> units that increases the living area will be charged $0.062 per square foot of increased <br /> living area. <br /> 1.3 Non-Residential Development Rates <br /> The SDC rate structure for non-residential development applies a land use factor to the <br /> number of Plumbing Fixture Units (PFUs) for a development. This factor is intended to <br /> capture different intensities of use of plumbing fixtures by different types of non-residential <br /> customers. The factors were developed based on an analysis of actual water usage by <br /> land use category, correlated to PFUs. The number of PFUs for a particular development <br /> is determined using the PFU tables and calculation methods contained in the applicable <br /> Plumbing Code at the time of permit application. <br /> The local wastewater rate schedule shown in Attachment 2, Page C-5 reflects rates per <br /> PFU for various development types indicated by an SDC use code. Developments are <br /> assigned an SDC use code based on the HUD/BPR land use code assigned at the time of <br /> permit application. For development types that are not included in the HUD/BPR land use <br /> codes a default PFU flow assignment, based on the average flow per PFU of all records in <br /> the data sample used to determine flow per PFU by land use category, will be used to <br /> calculate the SDC charge. When, due to extraordinary wastewater discharge flow, it has <br /> been determined by the City Engineer that PFU flow assignment as reflected in the rate <br /> table is not a reliable measure of the development's claim on system capacity, the SDC <br /> charge will be based on the development's estimated daily wastewater flow when in full <br /> use or production. The City Engineer may require that the owner(s) enter into an. <br /> agreement with the City to review water usage or wastewater discharge at such time the <br /> velopment is in full use or production. <br /> <br /> City of Eugene SDC Methodology Wastewater, Page C-3 <br /> <br />
