Pacific Water Resources, Inc. <br /> Dragonfly Bend Habitat Enhancement (DBHE) Project <br /> City of Eugene Public Works Department <br /> Project #4168 <br /> PACIFIC SCOPE OF WORK <br /> WATER RESOURCES, INC. <br /> October 24, 2003 <br /> Project Understanding <br /> The City of Eugene requires an initial review of fluvial geomorphic processes to support <br /> its Dragonfly Bend Habitat Enhancement (DBHE) project. The results of this analysis <br /> will be incorporated into an environmental assessment (EA) prepared by others for the <br /> DBHE project. <br /> Goals for the DBHE project include habitat creation for endangered species (Fenders <br /> Blue Butterfly and the Western Pond Turtle) as well as wetland and riparian <br /> enhancement. Specifically, Pacific Water Resources (PWR) will provide an initial <br /> review and assessment of fluvial geomorphic processes existing at the project site and <br /> anticipated impacts produced by project construction. More detailed studies which might <br /> be recommended as part of this work are specifically outside this work scope. Detailed <br /> sediment transport, hydrologic or hydraulic analyses aze examples of services which lie <br /> outside this current project scope. However, the need for such future studies might be <br /> identified by this project effort. <br /> Approach <br /> PWR's approach to this project will focus on understanding the fluvial geomorphic <br /> processes present at the existing site. This requires an understanding of sediment <br /> transport processes at the watershed level. The work will then involve evaluating how <br /> the proposed design affects these processes and attempt to identify specific impacts. <br /> Understanding how these impacts support the project goals of habitat enhancement and <br /> <br /> _ creation will be the challenge of this assignment. <br /> <br />
