DRAFT WILLAMETTE RIVER GREENWAY DESIGN PLAN <br />Table 2.6 Test Site No. 6 <br />GPS Points Collected XX / XLF <br />Satellites Acquired 12 <br />Observations The test site is dense with tree canopy and understory vegetation <br />on either side of the bike and extending down to the riverbank, <br />which is mostly gravel bar and exposed bedrock at low flow. <br />Topography and vegetation indicate a drainage extending north, <br />where the mapped TOB was shown to include. Visual evidence <br />of seasonal flooding in the area. The drainage feature extending <br />north appears to be a feature distinct from the river channel. The <br />field observed TOB line generally follows riverside edge of bike <br />path east and west of test site. <br />Findings Due to dense vegetation, minimal GPS field data points were <br />recovered. Vegetation, although riparian, appears to be <br />associated with a distict drainage feature that intersects with the <br />river corridor. Applying methodology for adjustments, mapped <br />TOB line is adjusted to a 6' riverside offset from bike path and <br />extending along bike path east and west until joining with TOB <br />line clearlv established from GIS Hillshade data. <br />Map 2.1 displays the test site locations and adjusted TOB line, following the field investigation, in relation <br />to the Willamette River Greenway boundary, tax lots, and City Limits boundary. The map also displays <br />the proposed Willamette River Greenway setback line, which is discussed in the Willamette Greenway <br />Established Setbacks document. <br />M WILLAMETTE RIVER GREENWAY CODE AMENDMENTS I CITY OF EUGENI 42 <br />
