Lower Amazon Floodplain Analysis, Scope of Work Page 2 of S Pacific Water Resources, Inc. Greenhill Road drainage ditch, Groesbeck Channel, Dead Cow Creek, Amazon Creek, A3 Channel, and the Greenhill Tributary. The complexity of this assignment is too great for developing a detailed work plan at the outset. A full understanding of the problem and all the factors affecting it needs to be developed first. There may be many points along the way at which strategic decisions require us to alter our course or approach. At this point, the problem is so complex that various studies aze required to determine the best approach for moving forwazd. Approach PWR's approach to this project will be to perform the work in phases (i.e. tasks). Each phase or task will have a cleaz goal, an identified list of activities, deliverables, budget and schedule. This approach maximizes the value of the existing body of work and utilizes a deliberate, structured process for achieving the City's ultimate goals. This `phased' approach also provides PWR and the City with clear direction and confidence throughout the process. The first task or phase of work will develop an understanding of the azea's existing hydrology and hydraulics. Future task(s) will involve developing hydrologic and hydraulic models necessazy to achieve various project goals. At this time these goals include: determining the affect of the Corps wetland restoration project on the floodplain boundary in the vicinity of the project (i.e. some azeas currently in the FEMA "approximate A" zone may no longer be in the regulatory floodplaln as a result of the setback levees associated with this project), developing FEMA maps and submittals for a LOMB defining a regulatory floodplaln and, potentially, floodway, determining the most advantageous designation of the levees associated with the 1135 Wetland Restoration Project. It is also anticipated that this floodplain analysis will support the design of the Dragonfly Bend Habitat Enhancement Project, however any work done not directly related to this floodplain analysis objectives will be funded consistent with the task order for the Dragonfly Bend project. Other goals may emerge from this study as the process evolves. Work Scope The activities outlined below, combined with the level of effort identified on the attached "Fee Estimate for Lower Amazon Floodplaln Analysis" constitute the entire range of services to be performed for Task 1 only of this project. We anticipate that the total fee for this first task and the as-yet undefined Task 2 shall not exceed $50,000. However, given the hydrologic and hydraulic complexities described above, this estimate could change as we move through the process. PACIFIC WATER RESOURCES INC.
