5 <br /> <br /> <br />The Task Force did not discuss funding sources or other financing opportunities for any consensual <br />or majority recommendations. <br />Meeting notes, and guidance documents developed by the TAG are included in Appendix A. <br /> <br />The Task Force directed the TAG to use full period of record hydrology for its analysis. Based on <br />this direction, the analysis uses a 1-percent annual chance (100-year) discharge of 33,000 cubic feet <br />per second (cfs) at the USGS Fargo stream gage. <br /> <br /> <br />November 29, 2017 Task Force Meeting: <br /> <br />The TAG presentation, titled “Component Analysis” as well as technical data presented at the <br />November 29, 2017 Task Force meeting are included in Appendix B. Following is a summary of <br />project components that were developed and presented by the TAG: <br /> <br />• Western Tie-back Levee – This component shifts the Limited Service Spillway for the <br />dam/southern embankment to the west along an existing natural ridge. This reduces the <br />staging elevation and utilizes more storage in North Dakota. It was included in components <br />1, 3, 4, and 5 that were presented. <br /> <br />• Consideration of Distributed Storage – It is recognized that Distributed Storage provides <br />overall basin-wide benefit, but due to the implementation schedule and need for in-place <br />storage for potentially reducing the 100-year discharge for accreditation purposes, this <br />alternative was not analyzed as part of any components or alternatives by the TAG. To the <br />extent that distributed storage (owned by a public body) is constructed and operational prior <br />to completion of the Fargo-Moorhead project, the resulting changes in hydrology could be <br />incorporated into the Letter of Map Revision (LOMR) for the Fargo-Moorhead project. <br />Distributed storage completed after approval of the LOMR for the Fargo-Moorhead project <br />would serve to increase the level of risk reduction (beyond a 100-year event). <br /> <br />• Components #1a-1d - Additional Flows Through Town – The TAG presented information <br />on the impacts of increasing the flow through town from RS35’ to RS37’, RS38’, and RS39’. <br />Results were presented using the proposed project alignment. <br /> <br />• Component #2 – Levees Only – The TAG presented a conceptual ring levee plan that could <br />potentially achieve FEMA Accreditation and protect the communities of Fargo and <br />Moorhead. <br /> <br />• Components #3a-3c – Dam/Southern Embankment Alignments – The TAG presented 3 <br />conceptual revised alignments for the southern embankment/dam. These include the North <br />of the Wild Rice River (3a), Northern Alignment Alternative (3b) and Modified Storage Area <br />1 (3c) alignments. <br /> <br />• Component #4 – Northern Storage Option – The TAG presented a component that would <br />increase flows into the flood damage reduction area through the Sheyenne and Maple River
