1.2 Residential Development Rates <br />An analysis based upon 1997 Eugene Water & Electric Board (EWEB) residential account <br />data indicated a correlation between water usage and square feet of living area. The. <br />resultant 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 $266 plus the <br />total living area in square feet multiplied by a factor of $0.064. Additions to residential <br />units that increases the living area will be charged $0.064 per square foot of increased <br />living area. <br />1.3 1Von-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 cafculatio.n 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 />development is in full use or production. <br />City of Eugene.
