City of Everett I March 12,2012 Page 3 <br /> ■ GeoEngineers staff attending this meeting will include our project manager and principal in <br /> charge of the project. <br /> Deliverables <br /> • Meeting notes from the kickoff meeting. <br /> ■ Review comments on the City's survey and base map. <br /> TASK 2 - GEOMORPHIC ASSESSMENT <br /> GeoEngineers will perform a geomorphic field reconnaissance of tributary channel from the confluence <br /> with Powder Mill Gulch to upstream of the culvert crossing. The primary purpose of this task will be <br /> identify additional knickpoints that could migrate into the project reach and to determine an estimated <br /> scour depth or channel elevation to assist in the development of stream stabilization measures. The field <br /> reconnaissance will also serve to acquaint the design team to the site. From prior phases of this project <br /> much work has already been doneto evaluate the historic and current geomorphic conditions of the <br /> tributary channel and this task is intended to build upon prior phases of this project. As part of this task <br /> GeoEngineers will complete the following: <br /> • Characterize baseline geomorphic conditions; <br /> • Document areas of active channel incision and bank erosion; <br /> • Qualitative assessment of principle factor/factors controlling project area channel incision and <br /> bank erosion; <br /> ■ Estimation of potential scour depth or channel elevation within the project reach;and <br /> • Assessment of future downstream channel responses resulting from the channel <br /> restoration/stabilization project. <br /> is Recommend stability measures for support of adjacent land. <br /> Assumptions <br /> is City staff will obtain land owner agreements and access to the project reach for conducting field <br /> reconnaissance where private property must be crossed. <br /> Deliverables <br /> ■ Text to be included in the Draft/Final Basis of Design report outlining key findings from site visit, <br /> review of pertinent data, and understanding of dominant channel processes, and estimates of <br /> potential scour depth. <br /> • Photos documenting locations of interest. <br /> TASK 3 -SLOPE STABILITY ASSESSMENT <br /> GeoEngineers will use the results of previous geotechnical consultation and slope stability analyses within <br /> the project reach and provide recommendations for long term slope stabilization measures. The primary <br /> purpose of this task will be to utilize the survey and base map elevations and coordinate with the design <br /> team to develop slope stabilization measures that may be incorporated into the stream stabilization <br /> design. We anticipate our geotechnical services will include the following tasks: <br /> • Refine slope stability analyses using the new survey data; <br /> Q/� GEOENGINEERI <br /> 3 <br /> Ale No.0661-086-02 `t <br />
