Non-technical <br />requirements are generally defined as functional, public, or user needs affecting the use, operations, or maintenance of the project. Non-technica I positions may also be required when <br />alternative features have either equivalent, or no governing, technical requirements. ' • • ' t ' • :SUMMARY OF DEC!SIQN 'fOPIC: . . . Implementation of a project of the magnitude and <br />complexity of the FM Metro Flood Diversion Project requires that non-technical input, such as functional or public aspects of the project, be incorporated into the design process at <br />the earliest time. In addition, projects of this magnitude require that the nontechnical input be provided to the USACE in a timely manner. Positions on routine non-technical features <br />and requirements will be made at the lowest possible level on teams with USACE. However, some non-technical positions will have a significant impact on the project's cost, schedule, <br />or function. It is imperative that positions of this nature be made by the Board of Authority, which has members that represent governmental and regional entities who benefit from the <br />project. The following protocol will be used as guidance for elevating non-technical issues and changes that affect project design. Non-technical requirements or issues that require <br />review or approval by the Board of Authority or its committees include: 1. Non-technical requirements that may result in a potentially significant cost or savings 2. Non-technical requirements <br />that may significantly change land requirements for the project 3. Unique owner maintenance or operational requirements 4. Non-technical requirements that involve high level of public <br />interest In the cases when a non-technical issue or change needs to be elevated to the Board or its committees for input, the following process will be used : 1. Technical and/or administrative <br />staff identifies potential issues which meet the criteria outlined above and advise the Program Management Consultant {PMC). 2. Utilizing input from technical and administrative staff, <br />the PMC presents the issue to the appropriate Diversion Authority committee. 3. The applicable committee provides feedback and advice to the PMC, including whether a recommendation for <br />Board approval is required. 4. In cases that require the establishment of a position by the Board of Authority, the committee will refer the issue to the Board of Authority using the <br />formalized decision process. The PMC FM_DECISION PAPER_NONTECHNICAL PROTOCOL_FINAL_6-14-12.DOCX PAGE 1 OF 2 <br />DECISION PAPER will support this action by preparing a decision paper and obtaining input from technical and administrative staff. 5. Positions on non-technical requirements or issues <br />that are elevated to the Board of Authority or its committees should be made within 30 days of identification of the issue. 6. Non-technical requirements or issues that require a response <br />sooner than 30 days will be discussed with the Board Chairman for determination of appropriate action. Special sessions may be called for Diversion Authority committees or the Board <br />itself in order to expedite position development on critical issues. Virtual meetings may be used if needed.

This task order will continue development of the Recreation and Use Master Plan, including preliminary and final design development. Subtask A -Revise select components <br />of the master plan document to reflect the most recent diversion design. Modifications consist of the elimination of row crop agriculture on the left Excavated Material Berm (EMB), the <br />narrowing of the EMB widths, the realignment of the diversion near I-94, and the consolidated CR 31/4 bridge. Subtask B -Undulation Design – Outlet to I-94. Develop a design for an undulating <br />surface, consistent with concepts in the draft Recreation and Use Plan that can be incorporated into design documents. Task Order No. 8 -Work-In-Kind (WIK) $669,330 Description: This <br />task order will include requests by United States Army Corps of Engineers (USACE) for the Local Sponsor (Diversion Authority) to provide WIK services related to the Project. USACE is <br />allowed by the Federal process to request the Diversion Authority provide services as WIK for services that USACE would normally do, but that the Diversion Authority has resources or <br />particular expertise to perform. Subtask A – Meander Belt Width Analysis – The Diversion Channel will contain a low flow channel that will be sinuous to simulate a natural stream. This <br />subtask will estimate the stability of the low flow channel and its meander pattern over time. Subtask B – Identification and Assessment of Tie-Back Levees. This subtask will assist <br />the Authority and the PMC with identifying and assessing the impacts to the Project due to the possible reclassification of the tie-back levees. Assistance may include analysis and comparison <br />of of Federal, State of North Dakota and State of Minnesota regulations, identification of applicable design criteria, and recommendations for options for the project. Subtask C –EMB <br />Openings -Prior to operation of the Diversion, the Fargo-Moorhead area may experience flood events. The partially constructed works should not increase the impacts of flooding. This <br />subtask will determine the location and size of openings in the EMBs to prevent an increase in flood elevations from the “without project” condition. Subtask D – Diversion Inlet Gates <br />-The FM Diversion Feasibility Study recommended a fixed weir for the inlet to the Diversion Channel. A gated inlet may offer some advantages over the fixed weir. This subtask will develop <br />preliminary layout and sizing of a gated inlet to the Diversion channel, and determine advantages and disadvantages of a fixed weir and a gated structure, including reliability, operability, <br />and impacts on the volume, frequency, and duration of water in the staging and storage areas, as well as develop preliminary comparative cost estimates of each type of inlet. Item 5b. <br />(1) <br />TASK-ORDER-SUMMARY-06142012 2 Subtask E – On-Call Services -This subtask will allow Authority staff and the PMC to respond to requests for services not identified to date. Requests will <br />be documented in writing and authorized within the Board Chairman’s approval limit. Task Order No. 9 – Hydrology and Hydraulic Modeling $194,341 Description: This task order will provide <br />hydrology and hydrologic modeling services in order to advance design components of the Diversion Channel. Specific modeling subtasks include: modeling of Diversion inlets to determine <br />design flows, modeling to evaluate hydraulic impacts of various Diversion Channel sizes, extending model geometry of the Rush and Lower Rush Rivers, providing technical assistance and <br />support for the physical modeling of the Maple and Sheyenne River aqueduct structures, and on-call services as requested. Task Order No. 10 – Utilities Design $94,000 Description: This <br />task order will provide utility relocation plans, utility relocation designs, and performance specifications for the relocation of utilities from the Diversion outlet at the Red River <br />to I-94. Various utilities such as power lines, communication lines, gas lines, and water lines have been identified and located within the proposed Diversion Channel footprint. These <br />utilities will have to be relocated or abandoned prior to construction of the Diversion Channel. Some utilities will be relocated by contractors under contract with the Diversion Authority, <br />while others will be relocated by the utility owner.
