DRAFT WILLAMETTE RIVER GREENWAY DESIGN PLAN Other As documented in Appendix E: WG Permit History, the City has received 141 Willamette Greenway permit applications in total and 137 since Resolution No. 2592 was approved, which included: boundaries of the Willamette River Greenway for areas within the city limits; intent to review private development; map of final Greenway boundaries; compatibility review procedures, incorporated in zoning ordinances, that require development review and findings of compliance with the approval criteria. Not all of those applications resulted in approvals, some were withdrawn, and a few were denied. Of the approved permit applications, the only known applications that included the established of a WRG setback as part of the approval are discussed previously in this document. Proposed code amendments that accompany the Design Plan allow the use of setback lines established in the Willakenzie Area Plan, EC 9.3147 or EC 9.3715 as an alternative to compliance with the Design Plan WRG setback line. 3.4 DESIGN PLAN WRG SETBACK LINE Section 2.0 Top of Bank Determination discusses the mapping of a Willamette River TOB line in GIS using 2-foot contours, slope, and hillshade layer sets derived from the 2009 LiDAR data, and subsequent adjustments to that line based on the findings from a Field Investigation. The Willamette River TOB line is the basis for the application of the proposed WRG setback line. In 2005, the City adopted Ordinance No. 20352 which updated the Goal 5 Inventory within the UGB, adopted the Goal 5 Water Resources Conservation Plan, and amended the Eugene Code. The Ordinance established protection for the Willamette River, along with other riparian corridors, wetland, and upland wildlife habitat resource sites. The Willamette River was inventoried as one of the most extensive intact wildlife corridors in the region, providing habitat for a diversity of wildlife species including state- and federally-listed species and in consideration of the following factors: • It is one of the highest quality sites in the [Goal 5]5 Inventory, • It is the largest stream in the region, • The corridor contains a highly intact riparian plant community with a mature forest canopy that supports a wide range of terrestrial and aquatic wildlife species, • It has very high connectivity value, providing one of the most extensive and diverse habitat systems and wildlife corridors in the region, • It provides habitat for state- and federally-listed species, and • It provides habitat for numerous native fish species. The primary conservation measure implemented by Ordinance No. 20352 is the /WR Water Resource Conservation Overlay Zone (/WR Overlay Zone). The /WR overlay zone organizes riparian corridors into five categories (A, B, C, D, and E) and assigns a conservation setback to each category measured horizontally from the top of high bank, or when the top of high bank is not identifiable, from the line of ordinary high water (EC 9.4920(1)(c)1.). The Willamette River is listed as a Category A Stream with a conservation setback of 100 feet from the top of high bank and 120 feet from the line of ordinary high water. Within the conservation area, the /WR overlay zone restricts new development, removal of riparian vegetation, and other conflicting uses. 5 Goal 5 Water Resources Conservation Plan. City of Eugene.
