Ordinance Exhibit D DOWNTOWN RIVERFRONT LAND USE COMPONENTS CA 19-1, RA 19-1, Z 19-5, WG 19-3, ST 19-3, and SDR 19-2 April 19, 2019 Furthermore, the discussion in EC 9.6791(3)(b) demonstrates stormwater runoff from the development site is directed to the Willamette River through established man-made flood control facilities and outfalls. Stormwater from the development site is not directed to facilities under the jurisdiction of the Junction City Water Control District. Therefore, this standard is not applicable. (4) Underground Injection Control Systems. Stormwater runoff discharged in underground systems is also regulated through the federal Underground Injection Control (UIC) program under Part C of the Safe Drinking Water Act (42 U.S.C. § 300, Chapter 6A, Subchapter XII) and Oregon Administrative Rule Chapter 340, Section 044. This standard acknowledges that UIC's are not directly regulated by the NPDES MS4 permit and the City of Eugene beyond the verification of flood control standards identified in EC 9.6791(3) (a) and (b) of this code. UIC's have applicable statutes and regulation under the jurisdiction of the Oregon Department of Environmental Quality (ODEQ) and require additional permitting directly through a state agency. The development proposes to discharge all stormwater runoff into existing conveyances that outfall to established surface waters not under the jurisdiction of UIC regulations. No UIC's are proposed with this development. Therefore, the standards of EC 9.6791(4) are not applicable. Any UIC proposed with a future development permit shall be subject the standard of EC 9.6791(4) and the time of development permit application. EC 9.6792 Stormwater Quality. (2) Applicability and Exemptions. (f) The standards in EC 9.6792 (3) do not apply to land use applications or development permit applications within the S -DR Downtown Riverfront Special Area Zone. Instead, the standards at EC 9.3155(17) apply. The standards at EC 9.6792 for Stormwater Quality do not apply to land use applications or development permit applications within the S -DR Downtown Riverfront Special Area Zone. This development is fully within the S -DR Downtown Riverfront Special Area Zone, so the standard at EC 9.3155(17) applies instead. The following includes findings demonstrating consistency with the standards of the S -DR Downtown Riverfront Special Area Zone. EC 9.3155 S -DR Downtown Riverfront Special Area Zone General Development Standards (applicable to all property). (17) Stormwater Quality Control Standards.
