Eugene Ordinance Exhibit J <br />[Lane County Ordinance Exhibit G] <br />within the UGB. The City's previous determination of adequate information carries forward for this <br />corridor, including mapping, site visits, and information on quality and quantity. <br />For the Clear Lake UGB expansion area, in its May 2014 report PHS identified four reaches of the A-2 <br />Channel as riparian areas. In addition to being previously mapped in the City's GIS system, and by PHS as <br />part of their Goal 5 inventory work, on-site inspections of each identified riparian area were conducted <br />by PHS and by City staff to verify location and quality. The methodology used by PHS to assess the <br />condition of the riparian corridors (the Urban Riparian Inventory and Assessment Guide (URIAG) (DSL <br />1998)) is described in detail on pages 17-19 of their May 2014 report. PHS confirmed via an email on <br />December 6, 2016 that as part of their inventory and assessment, they utilized information from aerial <br />photographs, the National Wetlands Inventory, United States Geological Service maps, Oregon <br />Department of Forestry, Oregon Department of Fish and Wildlife and federal flood hazard maps. <br />Based on the available information, the City has determined that information about each potential site <br />is adequate, consistent with the above OAR. <br />(C) Determine the Significance of the Resource Sites <br />660-023-0030(4) - For sites where information is adequate, local governments shall <br />determine whether the site is significant. This determination shall be adequate if based on <br />the criteria in subsections (a) through (c) of this section, unless challenged by the <br />department, objectors, or the commission based upon contradictory information. The <br />determination of significance shall be based on: <br />(a) The quality, quantity, and location information; <br />(b) Supplemental or superseding significance criteria set out in OAR 660-023-0090 <br />through 660-023-0230; and <br />(c) Any additional criteria adopted by the local government, provided these criteria <br />do not conflict with the requirements of OAR 660-023-0090 through 660-023- <br />0230. <br />For riparian areas, there are no supplemental or superseding significance criteria set out in OAR 660- <br />023-0090 through 660-023-0230 as referenced in -0030(4)(b). Further, the City did not adopt any <br />additional criteria for this Goal 5 process as referenced in -0030(4)(c). Therefore, the determination of <br />significance was based on the quantity, quality and location information as referenced in -0030(4)(a). <br />For the Santa Clara UGB expansion area, in its October 21, 2014 memo, PHS found that there were no <br />riparian areas. However, as noted above, information taken from the acknowledged Goal 5 work that <br />pertains to adjacent land within the City's current UGB shows that there is a significant riparian corridor <br />with Goal 5 protections that continues from within the UGB into the Santa Clara UGB expansion area <br />(Riparian Corridor identified as E56 in the City / County 2005 Goal 5 work). In a memo from Alissa <br />Hansen dated November 28, 2016, she explains that Eugene staff have recommended that that riparian <br />corridor E56 be assigned the same protections within the expansion area that it currently has in the <br />areas already within the UGB. In this case, they are of the same quality, quantity, and location. <br />For the Clear Lake UGB expansion area, in their May 2014 report, PHS assessed the four identified <br />reaches of the A-2 Channel using the URIAG methodology. All four of the inventoried riparian areas rate <br />"high" for water quality functioning, due to the low slopes within the riparian area, the presence of <br />13 <br />May 2017 <br />
