Kinney Park Channel Restoration Project, Scope of Work Page 6 <br /> Pacific Water Resources, Inc. <br /> the model with: current and future land use information as provided by the City's <br /> GIS database, multiple flow frequencies (maximum of 8 total design storms), adding <br /> the east fork link, and evaluating pipe sizes in Martin St. <br /> 5. Perform Fluvial Geomorphic Investigations. As a follow-on to the field work <br /> performed earlier this activity will focus on determining geometric and alignment <br /> parameters for proposed channel improvements. The maps and hydraulic information <br /> gathered earlier will be used to support this activity. At this time we are aware of the <br /> need to stabilize ahead-cut and incision on the main channel as well as the desire to <br /> reestablish an historic tributary (the `east fork'). Working with the detailed <br /> topographic surveys provided by the City, this effort will attempt to define an `east <br /> fork' alignment and geometry which minimizes impact and disturbance on the forest <br /> area. (We understand that the City's survey includes the locations of significant <br /> trees.) The field work will also identify other issues which should be addressed such <br /> as clearing limits, access for construction equipment and coordination with proposed <br /> parks improvements. If additional information or measurements are needed then this <br /> activity will identify these via laths, flagging or other markings for City surveyors to <br /> measure precisely. The results of this investigation, including any needs for <br /> additional field measurements, will be coordinated with the City. A summary of <br /> important design features will be included with the Predesign Report discussed <br /> below. <br /> 6. Ident~ Possible Project Elements. Numerous elements may be used to achieve the <br /> City's goals. These include (but are not limited to): bioswales, stormwater filters, <br /> channel restoration, bioengineered bank stabilization, large woody debris (LWD), <br /> detention facilities, sediment manholes or sumps, pipe/culvert reconstruction and/or <br /> realignment, channel grade controls, floodplain reconnection, native plantings, <br /> vegetation management, etc. The purpose of this task is to work with the City to <br /> develop a palette of elements which may be incorporated into this project to achieve <br /> the identified goals. Only elements which are applicable to satisfying project goals <br /> will be considered. As the goal of the Predesign Phase is to determine feasibility, <br /> only elements which can be successfully applied to this particular site will be <br /> considered. Applicability of particular project elements will also be considered in <br /> light of proposed park facilities and their `fit' with the park concepts for access and <br /> use. The results of this task will be included in the Predesign Report described <br /> below. <br /> 7. Attend a Meeting with Regulatory Reviewers. With an understanding of site <br /> hydrology, fluvial geomorphology, the City's goals and a list of available project <br /> elements, PWR will attend a meeting with regulatory personnel and the City to <br /> discuss the project. The meeting should be setup and facilitated by the City. PWR <br /> will present the project objectives, proposed elements and known design constraints <br /> based on the studies and information available at that time. PWR will also document <br /> the meeting discussion outlining issues and concerns raised by the regulatory <br /> agencies. <br /> <br /> 8. Assemble Elements into Project Alternatives. Having reviewed the project within the <br /> regulatory context (above), develop a comprehensive solution using elements already <br /> discussed. If appropriate, identify one alternative using a different design approach or <br /> concept. The final results of this task will be submitted with the Predesign Report <br /> PACIFIC <br /> WATER RESOURCES, INC. <br /> <br />
