<br />v. Update stormwater pond designs for 100-year levee <br />earthwork quantities. <br />vi. Provide roadway replacement plans and traffic control for <br />gravity drain construction area on Cass County Highway 81. <br />vii. Update pump station design based on 100-yr levee scenario. <br />Includes reconfiguration of pump station elevation as well as <br />general civil for access, etc. <br />viii. Update DDRs for WP-43C and WP-43D, including interior <br />flood control, to include 100-year levee design <br />documentation. <br />ix. Provide QA/QC review of design modifications. <br />3. Comstock – Ring Levee Evaluation: <br />a. Prepare a proposed ring levee system to reduce flood risk to <br />Comstock, MN during operation of the Diversion Project and staging of <br />water. Show the location of a potential ring levee, develop height <br />required for rink levee, and evaluate access during periods of <br />Diversion operation. <br />4. Christine – Ring Levee Evaluation: <br />a. Prepare a proposed ring levee system to reduce flood risk to Christine, <br />ND during operation of the Diversion Project and staging of water. <br />Show the location of a potential ring levee, develop height required <br />for rink levee, and evaluate access during periods of Diversion <br />operation. <br />5. Wolverton – Ring Levee Evaluation: <br />a. Prepare a proposed ring levee system to reduce flood risk to <br />Wolverton, MN during operation of the Diversion Project and staging <br />of water. Show the location of a potential ring levee, develop height <br />required for rink levee, and evaluate access during periods of <br />Diversion operation. <br />6. Staging Area – Non-Structural Improvement Evaluation: <br />a. Identify individual residential properties within the staging area and <br />evaluate the potential benefit from non-structural improvements to <br />reduce flood risk to residential structures during operation of the <br />Diversion Project and staging of water. Show the location of potential <br />improvements and evaluate access during periods of Diversion <br />operation. <br />i. Provide mapping of residential structures and farmsteads <br />impacted by the Staging Area for the 100-year event, and <br />include estimated depth of impact for the structures with and <br />without the project. <br />ii. Where technically feasible, provide concept for non- <br />structural improvements and estimate cost of improvements. <br />iii. Develop database of impacted properties that includes <br />relevant project information (such as depth of impact with <br />and without project, etc.) <br />HMG-TO-13-A10_Long.docx 15 <br />DR <br />A <br />F <br />T
