<br />Ordinance -- Page 8 of 9 <br />(c) All facilities to control the rate of stormwater runoff shall be sited, designed and <br />constructed according to the flow control provisions and the facility design requirements set <br />forth in the Stormwater Management Manual. Flow control facilities must be designed using <br />one of the methodologies outlined in the Stormwater Management Manual. <br /> <br />(d) The standards in EC 9.6793(3) may be adjusted pursuant to EC 9.8030(24). <br /> <br /> <br />Section 4. Subsections (24)(a) and (24)(b) of Section 9.8030 of the Eugene Code, <br />1971, are amended to provide as follows: <br />9.8030 Adjustment Review – Approval Criteria. <br />The planning director shall approve, conditionally approve, or deny an adjustment review <br />application. Approval or conditional approval shall be based on compliance with the following <br />applicable criteria. <br />* * * <br />(24) Stormwater Quality, Flow Control, Oil Control and Source Control Standards Adjustment. <br />(Adjustments under this subsection are not permitted within the /CL Clear Lake Overlay Zone.) <br />(a) The requirement in EC 9.6792(3)(e)(3)(a) and EC 9.3155(17)(c)4 that selected <br />stormwater quality facilities shall treat all the stormwater runoff that will result from the water <br />quality design storm may be adjusted upon a finding that the stormwater quality facility will <br />treat as much of the runoff as possible; and <br />(b) The requirement in EC 9.6792(3)(f)(3)(a) and EC 9.3155(17)(c)5 that all stormwater <br />quality facilities be selected from and sited, designed, and constructed according to the <br />stormwater quality provisions and the facility design requirements set forth in the Stormwater <br />Management Manual and that stormwater quality facilities must be designed using one of <br />the methodologies outlined in the Stormwater Management Manual may be adjusted upon <br />finding that all of the following requirements are met: <br />1. The proposed alternative design will achieve equal, or superior, results for function <br />(reducing pollution), maintainability and safety, and the proposed siting does not <br />adversely affect structures or other properties. <br />2. The applicant’s written description of the proposed alternative design has been <br />reviewed and approved by the City Engineer. The description of the proposed design <br />submitted for review must include all of the following information for each component <br />of the proposed alternative design: <br />a. Size, technical description, capacity, capital cost, design life, construction <br />process and costs, consequences of improper construction, operation and <br />maintenance requirements and costs;
