ANNUAL INSPECTION <br /> AMAZON CREEK CHANNEL IMPROVEMENT <br /> PROJECT NO. 15-01 <br /> 28 AUGUST 2002 <br /> 1 . DATE OF INSPECTION: 14 August 2002 <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 /> Richard Zucker, Maintenance Crew Supervisor, (541) 682-4833 <br /> Trevor Taylor, Natural Resources, Operations Coordinator <br /> John Todd, Inspector, CENWP-EC-DC, (503) 808-4915 <br /> 5 . FINDINGS : The following inspection findings were noted: <br /> a . The City is continuing to work with environmental <br /> advocates to limit vegetation removal to only that which is <br /> necessary to ensure the channel capacity is not limited and <br /> unwanted vegetation will not result in backwater. Selective <br /> brush and tree removal is recommended in the channel between 30th <br /> Avenue and 33rd Avenue; upstream of 29th Avenue; and along the <br /> Fairgrounds, to ensure adequate velocities during times of high <br /> flow. <br /> b. Sloughing along the channel side slope was noted on the <br /> left bank immediately downstream of Garfield Street (4 areas on <br /> the left bank, each approximately 40 lineal feet) . Repair of <br /> these areas are scheduled for later this year or next year. An <br /> A/E firm prepared a report for the city that indicates the <br /> channel bottom in the vicinity of Garfield Ave has dropped <br /> approximately 4 feet . Computer modeling by the A/E indicates <br /> that the banks fail due to bank storage of water during and after <br /> high-discharge events . <br /> c. Between Acorn Park Street and Oak Patch Road, the city <br /> has constructed the Amazon Creek Widening Project . The project <br /> has widened Amazon Creek along this stretch and returned the <br /> creek to a more natural condition. <br />
