(c) South Hills at Fox Hollow ditch (E37 J-4): Fully allowing conflicting uses recommended. This portion of the South Hills complex (E37J-4) is a short, narrow drainage channel with virtually no riparian vegetation. From these resource characteristics, it is evident that this segment is a lower quality site. Based on that, and the ESEE analysis above, fully allowing conflicting uses is recommended for this site. For this lower quality site, the positive consequences of protecting the resource are not great enough to outweigh the negative consequences of prohibiting or limiting conflicting uses. Conflicting uses that would be allowed in this site are more important than its lower resource values. (4) South Hills at Canyon Drive/Fox Hollow (E37K); and (5) South Hills at Center Way (E37L): Limiting conflicting uses recommended. These stream corridors (E37K and E37L) have resource characteristics that make them higher quality sites. Although portions of the sites have been thinned or constricted by adjacent development, and have open areas where invasive species are established, the riparian habitat in these corridors is still relatively intact Overall, they are dominated by primarily native species, and have a moderately high diversity of riparian and upland plants. The steep slopes of the stream and the surrounding area increase the value of the riparian area for protecting downstream areas from erosion and water quality degradation. These sites are also valuable for their connectivity, as they connect the higher forested areas of the Ridgeline Trail park system to lower elevation habitats. Based on these key resource characteristics, and the ESEE analysis above, limiting most conflicting uses is recommended for these sites. The resource values provided by these sites are more important to the broader community, than the conflicting uses that would occur here. The negative economic, social, environmental and energy consequences offully allowing conflicting uses within these sites outweigh the positive consequences. The positive economic, social, environmental and energy consequences of prohibiting conflicting uses within these sites outweigh the negative consequences. However, limiting most conflicting uses would adequately protect the resource while allowing for some uses with minimal impacts to the resource. Therefore, the positive economic, social, environmental and energy consequences of limiting conflicting uses within these sites outweigh the negative. The positive economic, social, environmental and energy consequences of limiting conflicting uses outweigh the positive consequences that would result if all conflicting uses were prohibited. Therefore, limiting conflicting uses is recommended for these sites. (6) South Hills at Dillard: (a) South Hills at Dillard Hollow: Limiting conflicting uses recommended. This site (E37M-l, M-3) is one of the most intact stream corridors the South Hills. The riparian area is dominated by native plants, including riparian, upland, and wetland plant species, and has high structural (tree/shrub/groundcover layers) diversity. In addition to having a high quality riparian plant community, the site has high connectivity, providing a wildlife corridor between the extensive Ridgeline Trail park system and habitats at lower elevations. Therefore this site is a higher quality site. Based on these key resource characteristics and the ESEE analysis above, this site is more important to the broader community than the conflicting uses that would occur within the two reaches of this stream. The negative economic, social, environmental and energy consequences offully allowing conflicting uses within this site outweigh the positive consequences. The positive economic, social, environmental and energy consequences of prohibiting conflicting uses within these sites outweigh the negative consequences. However, limiting most conflicting uses would adequately ESEE Analysis Page 15 October 24,2005 replacement page
