iL • Odor is a problem, especially along the concrete channel. • Illegal camping along Amazon Creek is a significant source of pollutants. • Amazon Creek is a key contributor to the quality of life in Eugene (both good and bad). • Degradation of wildlife habitat along the creek due to poor water quality, vegetation removal, and exotic plant and animal species is an issue. • Future development in the headwaters will worsen water quality and flood risk. • The Fern Ridge bike path should be extended west. • If the concrete channel can't be removed in all places it could be modified with a low flow channel to concentrate the flow. • The channel could be widened in numerous places to improve habitat and aesthetics. • Restore vegetation along the Roosevelt Channel. • Restore the Golden Garden Ponds. • Channel widening and enhancement opportunities exist on Amazon Creek ("A" Channel) to the north of the Diversion Channel. • Water quality is extremely poor on the A-3 Channel. • Consider making the connection between the Eugene Millrace and Amazon Creek (Emerald Canal) over time. • The large culverts flowing into Amazon Creek should be considered for day-lighting where feasible. • A number of local resources such as the Citizen Nature Project and the Rachel Carson School water quality study could be incorporated into the study. Cedar Creek Planning Corridor Comments from February 24 Staff and Technical Assistance Pool Site Visit: • The 50-year old Corps revetment along the McKenzie River has significantly deteriorated in locations and it appears as though the McKenzie mainstem could potentially change course, forging a new connection with Cedar Creek though the prime agricultural lands in the floodplain. • Bank Erosion along the McKenzie River is an issue in numerous places. The former Matthews home site, where the house was recently undercut by the river, is a good example of the unpredictability of the river. • Flooding is an issue over much of the lower Cedar Creek basin. Flood water can originate both from upland runoff and the McKenzie River topping its bank as occurred in the 1996 flood. • Based on the 1996 flood event, the floodplain mapping for the Cedar Creek basin is out of date. • Logging in the headwaters is resulting in increased sedimentation. • The SUB well fields in the basin could potentially be impacted by pollutant carried by Cedar Creek. • Increased urbanization in the basin will likely result in increased peak flow runoff and increased pollutant loads.
