This has been developed by the City at the conceptual <br /> level. <br /> • Algae growth and heating of the water during the summer months is an issued in the <br /> concrete sided channel between 24tH Avenue and the fairgrounds. Sufficient space is <br /> currently available for potentially removing the concrete channel between 24tH Avenue. <br /> • Creating a low flow channel at the bottom of the concrete channel could be used <br /> concentrate flow as a method of reducing algae growth and water heating. Placing <br /> boulders, gravel, or deflectors in the bottom of the concrete channel could also be a <br /> technique for simulating a more naturally functioning channel bottom. <br /> • Channel widening opportunities exist on central Amazon Creek at the Lane County <br /> fairgrounds. The Lane County fair board has been working with neighborhood <br /> representatives and local consultants to develop this concept. <br /> • Bank failure and bed scour is occurring in the segment between Polk Street and Oak <br /> Patch Road. Several areas are well suited for channel widening in this segment. <br /> • Opportunity exists for potentially day-lighting several large stormwater culverts entering <br /> Amazon Creek in Westmoreland Park. <br /> • The area between Chambers and Oak Patch is the most likely area to flood <br /> • The Nature Conservancy has recently purchased the Cuddeback property-north of 18tH <br /> Avenue for wetland restoration. The east branch of Willow Creek has been diverted <br /> around this area. An opportunity exists for re-directing the flow back into the historic <br /> channel. <br /> • Portions of Amazon Creek and the A-3 Channel are highly polluted and fall within the <br /> DEQ's 303d list for temperature, dissolved oxygen, bacteria, and toxic materials. <br /> • Several potential barriers to fish passage exist along Amazon Creek, mostly at <br /> engineered drop structures. <br /> • Rip-rap placed directly into the channel bottom of the creek prohibits its use for <br /> recreational boating. <br /> • Several good examples of channel enhancements along Amazon Creek have been <br /> implemented over the past nine years and may serve as a good model for future <br /> enhancements. <br /> • The local partners should provide the Corps with electronic copies of key documents and <br /> data. <br /> • A compilation map showing the location of issues and opportunity that have been <br /> identified to date on both of the priority planning corridors would be a helpful planning <br /> tool. <br /> Summary of Public Comments: <br /> The list below is a generalized summary of the nature of the public comments received as of <br /> February 2005 that are related to issues and opportunities. A full listing of public comments <br /> is contained in the Metro Waterways Citizen Involvement Summary Report (February 2005). <br /> • Water quality is a significant issue in Amazon Creek and its tributaries (most frequently <br /> stated issue). <br /> • Clearing brush along the creek diminishes wildlife habitat and is unsightly. <br /> • Public access down to the water is very limited along Amazon Creek. <br /> <br />
