PURPOSE <br /> Amazon Creek may experience very high water conditions during periods of significant <br /> rain or even as a result of an individual storm event. It is important that City staff be <br /> prepared to keep the structural components of the Amazon Creek Flood Control Works <br /> Project functioning properly in order to protect life, property, and the environment. This <br /> plan is aimed at assisting with that preparation. <br /> Therefore, the intended purpose of this emergency response plan is fourfold: <br /> • Document available resources, including personnel, equipment, and materials as <br /> well as additional sources of these to be used in an emergency situation. <br /> • Provide a set of protocols and procedures for the City's and other agency's staff <br /> to follow in the event of a high water, flooding, or levee integrity emergency along <br /> the Amazon Creek Flood Control Works. <br /> • Identify unique conditions of this project that pose issues and concerns related to <br /> personal safety and /or operations and maintenance activities. <br /> • Document actions or conditions that will help maintain or enhance the City's <br /> preparedness for a flooding or levee integrity emergency along this project as <br /> well as throughout the other portions of the City's open drainage system. <br /> BRIEF DESCRIPTION - AMAZON CREEK FLOOD CONTROL WORKS <br /> The Amazon Creek Flood Control Works Project extends from the Hilyard Street / 33 <br /> Street intersection in south Eugene downstream to the boundary of Corps of Engineers <br /> property along the east side of Fern Ridge Reservoir, a total distance of approximately <br /> 10.7 linear miles of creek bed. The project was constructed by the U.S. Army Corps of <br /> Engineers in the mid- 1950's to achieve several primary goals. The first was to alleviate <br /> chronic bank overtopping problems in Eugene and downstream areas by straightening, <br /> widening, and deepening the natural bed of Amazon Creek. The second was to divert a <br /> large majority of the flow from the natural creek bed to Fern Ridge Reservoir. Upon <br /> completion of the various phases of the overall project, the City of Eugene took over <br /> management responsibility under the authority of several agreements with the Corps. <br /> As modified in the mid -1990s by the Lower Amazon Restoration Project, the flood <br /> control works now consists of 5 significantly different types of features. <br /> • The greatest number of linear miles consists of a widened excavated trapezoid <br /> shaped channel with no levees and some form of access along the top of bank. <br /> • Through a majority of the downtown core, the project consists of a rectangular <br /> shaped concrete Tined channel with no levees and relatively little access along <br /> the top of the bank except at the numerous vehicles bridge crossings. <br /> Emergency Response Plan for Amazon Creek 2 September, 2008 <br /> P: \Cdocs\AP WARefDocs \Emerge ncyMg mt <br />
