f . <br /> portion of the charge will be modified to reflect the value of the new schedule of capacity <br /> increasing improvements, and the modified fee will be applied to the development that caused <br /> the need for the modification and to all future development. <br /> 5.0 stormwater System <br /> The stormwater SDC is based upon the square footage of all impervious surface {e.g., rooftops, <br /> driveways, sidewalks, parking lots, patios, and other non-porous surfaces). The detailed formula for <br /> calculating the stormwater SDC cost per square foot of impervious surface is set forth in Appendix <br /> D. The stormwater SDC is determined by multiplying the applicable rate by the unit of measure, for <br /> <br /> the proposed development type. The stormwater SDC rates per unit of measure can be found in the <br /> current adopted fee schedule in Appendix F. <br /> <br /> Where the stormwater SDC is a fixed amount per dwelling unit or space, it shall be determined by <br /> multiplying the amount per dwelling unit or space times the number of units or spaces plus, for ~ <br /> manufactured home development, the amount for other features based upon the impervious area <br /> <br /> times the rate for square footage. Where the stormwater SDC is not a fixed amount per dwelling unit <br /> or space, it shall be determined by multiplying the rate per square foot of impervious area times the <br /> impervious area of the proposed development. Where a development creates impact not attributable <br /> to impervious surface area, the stormwater SDC shall be determined by evaluating equivalent <br /> impervious surface area, multiplied by the rate per square foot of impervious area. <br /> 6.0 Parks System <br /> The parks system components that are identified in the adopted 1989 Parks and Recreation Plan, <br /> and the parks system components identified in Table 7, which are used to calculate the parks SDC, <br /> are generally described as parks (neighborhood and community) and facilities which are more <br /> particularly described in AppendixrE. The current community standard, or level of service, for an <br /> infrastructure system is the determining factor in calculating the impact of new development on the <br /> system. New development can be charged the costs of providing infrastructure services for the <br /> development at the same level of service as the existing community as a whole. <br /> The detailed calculation for each component of the parks SDC and the Cost of Service formula are <br /> set forth_in Appendix E. The parks SDC rate can be found in the current adopted fee schedule in <br /> Appendix F. The rate per dwelling unit is determined based on equivalent dwelling units (EDU). <br /> The parks SDC for a proposed development is determined by multiplying the rate per dwelling unit <br /> (EDU) by the number of dwelling units in the proposed development. The cost per EDU is the sum <br /> of all parks system components identified in AppendixE. There is currently no parks SDC for non- <br /> residential development. <br /> 7.0 Credits and Impact Reductions <br /> This section provides detail on the City's administration of SDC credits and impact reductions. <br /> Potential sources, criteria for eligibility, and the basis for calculation of credit and impact reductions <br /> are defined in the SDC Credit Policies and Procedures, in this Methodology, and in Eugene Code, <br /> section 7.730. A list of examples of facilities and programs which are potentially eligible for credit and <br /> impact reduction appears in Table 2 of this section. (Note: As development standards change some <br /> exam les may no longer be considered eligible for reduction but may influence future rates.) <br /> SDCs may be reduced by one or more of the following processes: <br /> City of Eugene SDC Methodology Page 10 <br /> <br />
