b. The existing Amazon Creek project, even if adequately maintained, <br /> falls short of providing 100-year flood protection by about 800 cfs of flow. <br /> c. The risk of flooding from Amazon Creek is aggravated by the fact that <br /> the Amazon Creek channel has not been maintained by the local sponsor to <br /> design capacity. This lack of maintenance has reduced the present capacity of <br /> the channel by about 20 percent in some locations. <br /> d. There appears to be no economically feasible solution to meeting the <br /> identified flood-damage-reduction needs of Amazon Creek Basin. <br /> e. Although the Emerald Canal diversion cannot be economically justified <br /> for flood control, the concept of the canal offers a unique opportunity to <br /> meet recreationally-oriented needs in the basin. <br /> Recommendations <br /> In view of the findings of this study, no structural improvements for <br /> water-related resources development in the Amazon Creek Basin should be under- <br /> taken at this time by the Corps of Engineers. I recommended that local <br /> government agencies implement and enforce appropriate floodplain management <br /> measures including annual notification to local residents concerning the <br /> limits of the floodplain and severity of flood threat. <br /> The Corps of Engineers will continue to assist local government agencies <br /> with floodplain management through the Floodplain Management Services Program. <br /> In addition, the city of Eugene under the existing local cooperation <br /> agreement should restore the Amazon Creek channel to its designed capacity, <br /> and then maintain the channel to its capacity. <br /> JON D.
