4.1. Conduct a rapid geomorphic analysis using newly obtained survey information, <br />geotechnical reports, aerial photos, and findings from the field reconnaissance. This <br />activity will investigate channel banks and bed and determine potential for future <br />lateral migration and/or channel downcutting which supports justification of the most <br />appropriate bridge span width. <br />5. Hydraulics <br />5.1. Perform hydraulic modeling to ascertain the hydraulic characteristics necessary to <br />support the design of the new bridge crossing and potential scour countermeasures for <br />the protection of the roadway prism. <br />6. Bank Stability Assessment and Design <br />6.1. Examine stability of the existing scour protection and river banks utilizing various <br />design manuals such as, Integrated Streambank Protection Guidelines (ISPG), HEC -18, <br />HEC -23, etc. <br />6.2. Coordinate with the COUNTY to identify proposed measures that are acceptable from a <br />channel stability and habitat perspective. If scour/bank projection measures are <br />needed, continued coordination with the COUNTY will occur to develop design <br />concepts. <br />7. Scour Analysis <br />7.1. Compute depth of scour estimates for the proposed bridge waterway and for any <br />necessary scour countermeasures. <br />8. Team Meetings & Permitting Assistance <br />8.1. Participate in bi-weekly (or as needed less frequently) team meetings via conference <br />call. <br />8.2. Assist with the team's preparation of permit applications and answer questions that <br />arise during agency review. <br />9. Temporary Diversion Assistance <br />9.1. Conduct a hydrologic analysis using the available data to determine potential flow <br />during the anticipated construction window. Calculated flows will be modeled with the <br />model developed for the project design with the anticipated location of the diversion <br />provided by KCPW. <br />9.2. Coordinate with the COUNTY to determine an appropriate flow to put into the <br />construction contract. <br />10. Documentation <br />10.1. Produce the following documents: <br />10.1.1. Preliminary Basis of Design Memo <br />10.1.2. Draft Basis of Design Report <br />10.1.3. Final Basis of Design Report <br />11. DELIVERABLES <br />11.1. One (1) Preliminary BOD Memo. <br />11.2. One (1) Draft BOD Report. <br />
