ANNUAL INSPECTION <br /> AMAZON CREEK CHANNEL IMPROVEMENT <br /> PROJECT NO. 15-01 <br /> 31 AUGUST 1993 <br /> 1. DATE OF INSPECTION: 26 August 1993 <br /> 2 . REFERENCE: LEVEE ENCROACHMENT STANDARDS AND PROCEDURES, <br /> PDR 1130-2-5, 17 March 1980 <br /> 3. SPONSOR: City of Eugene <br /> 4 . INSPECTION PARTICIPANTS: <br /> John Todd, Inspector, CENPP-PE-DC, (503) 326-6491 <br /> Richard Zucker, Maintenance Supervisor, (503) 687-5271 <br /> Jack Long, Environmental Technician, (503) 687-5207 <br /> 5. FINDINGS: The following inspection findings were noted: <br /> a. Clearing of unwanted vegetation from the channel (lined <br /> and unlined) and channel side slopes was noted at various sections <br /> of the project. The City is continuing to conduct clearing <br /> operations from the channel as an ongoing process. The City is <br /> also working with environmental advocates to limit vegetation <br /> removal to only that which is necessary to ensure the channel <br /> capacity is not limited and unwanted vegetation will not result in <br /> backwater. Brush and tree removal/thinning is recommended <br /> downstream of 33rd and Hilyard Street; upstream of 31st and Hilyard <br /> Street; downstream of 29th Avenue and upstream of 24th and Amazon <br /> Parkway. <br /> b. Sediment deposition was noted upstream and downstream of <br /> bridges located at 24th, 29th, 30th, 31st, and 33rd Avenues. The <br /> sediment will limit the capacity of channel in these areas. <br /> c. Berry vines were noted on the right bank of the channel <br /> side slope between Jefferson Street Bridge and Polk Street (approx. <br /> 2500 feet in length) . The vines restrict inspection of the channel <br /> and create habitat for burrowing animals. This finding was noted <br /> in the 1991 inspection report. <br />
