40% of this site as a whole is located within the City -owned Ridgeline Trail park system, which is <br /> managed as a natural area. Five of the six sites within this analysis group are crossed by the Bonneville <br /> Power Administration powerline easement. The uppermost ends of several stream corridors are just <br /> outside of city - limits. The short ditch at Fox Hollow (E37J -4), and approximately 1,000 feet of upper <br /> portion of E37K, are located entirely outside of city limits. The remaining sites in this analysis group are <br /> within city - limits. <br /> 17.2 Impact Area <br /> Sites E37 H (S Hills at Upper Owl Road); E37I (S Hills at St. Clair); E37J (S Hills at <br /> Lower Owl Road /Fox Hollow); E37K (S Hills at Canyon Drive /Fox Hollow), E37L <br /> (S Hills at Center Way); E37M (S Hills at Dillard); AMA -13 (Owl Road wetland) <br /> OAR 660 - 023 - 0040(3) requires local governments to establish an impact area for each site. <br /> This impact area is based upon: 1) surrounding allowed uses; and 2) potentially adverse effects <br /> of those uses. The impact area for riparian and upland wildlife habitat sites is measured from <br /> the top of bank and includes any riparian vegetation within the mapped site boundary that <br /> extends beyond the measured distance. The impact area for wetlands is measured from the <br /> wetland boundary. The factors considered in establishing the impact areas for this site, and <br /> how the impact area is measured, are discussed in more detail in Sections 2.4 and 2.5, Impact <br /> Areas. Table 17.2 below lists the impact areas assigned to these Goal 5 sites. <br /> Table 17.2 Impact Area Summary: Portions of South Hills Upland Stream Corridors at <br /> Upper Amazon (Owl Road to Dillard) & Upper Amazon Wetlands <br /> Sub <br /> # Site Name Impact Area* <br /> South Hills at Upper Owl Road: <br /> E37 H S Hills at Upper Owl Road Type C - 50' + mapped riparian vegetation <br /> South Hills at St. Clair': <br /> E37 I S Hills at St. Clair Type C - 50' + mapped riparian vegetation <br /> South Hills at Owl Road /Fox Hollow: <br /> E37 J -1 S Hills at Lower Owl Road south Type C - 50' + mapped riparian vegetation <br /> E37J -2 S Hills at Lower Owl Road north Type C - 50' + mapped riparian vegetation <br /> AMA -13 Owl Road wetland Type D - 25' <br /> E37 J -4 S Hills at Fox Hollow ditch Type C - 50' + mapped riparian vegetation <br /> E37 J -5 S Hills at Donald /Fox Hollow Type C - 50' + mapped riparian vegetation <br /> South Hills at Canyon Drive/Fox Hollow; South <br /> Hills at Center Way; <br /> E37 K S Hills at Canyon /Fox Hollow Type C - 50' + mapped riparian vegetation <br /> E37 L S Hills at Center Way Type C - 50' + mapped riparian vegetation <br /> South Hills at Dillard: <br /> E37 M -1 S Hills at Dillard Hollow Type C - 50' + mapped riparian vegetation <br /> E37 M -2 S Hills at Dillard ditch Type C - 50' + mapped riparian vegetation <br /> E37 M -3 S Hills at Dillard upper Type C - 50' + mapped riparian vegetation <br /> * The impact area for riparian sites is measured from the top of bank and includes any riparian <br /> vegetation within the mapped site boundary that extends beyond the measured distance.
