No major <br /> <br /> Ili defects wer reported or observed in the 35 miles of major drainage channels maintained by <br /> <br /> ~I the Eugene Public Works Department. These channels include the Amazon as well as the <br /> North Beltl ne Floodway and the Roosevelt Channel. Another area that came through with <br /> flying Colo s was the north side of Airport Road, which had always flooded during heavy <br /> rains in the past. As a result of extensive reditching and maintenance work completed last <br /> <br /> I, summer, th s area did not flood at all, even on January 13, when a record 4.15 inches of rain <br /> <br /> ~I <br /> fell. <br /> <br /> !i A t rning point in the management of the Amazon came in 1983, following a report <br /> by the U.S Army Corps of Engineers on the flood control effectiveness of the creek. The <br /> <br /> ~i <br /> <br /> I, report fou d that Amazon Creek, which was completed in 1959 as a Corps' flood control <br /> <br /> ~I <br /> project, ha lost as much as 20 percent of its original capacity to carry stormwater. The main <br /> causes of t e reduced capacity were sediment buildup and large amounts of woody growth. <br /> In rder to return the Amazon to its designed flood capacity, the City put the Amazon <br /> on a seven year maintenance cycle. The City removed sediment deposits, repaired damaged <br /> banks, and began an aggressive streamside vegetation management program. This is an <br /> <br /> i <br /> ongoing m intenance effort. In 1994, for example, a $170,000 project was completed to <br /> stabilize a ded and undercut banks of the Amazon between Bailey Hill Road and Buck <br /> Street. <br /> (mo~~e) <br /> News Rel ase CREEK MAINTENANCE <br /> <br />
