<br />TASK_ORDER_SUMMARY_2014‐0313.DOCX 2 <br />TASK ORDER SUMMARY <br />HMG – Task Order No. 9 – Amendment 10 Increase $ 25,000 <br />Hydrology and Hydraulic Modeling <br />Description: <br />Subtask 2.I.V.i – Services of Engineer <br />i. Update HEC‐RAS unsteady flow model geometry to reflect most current layout of the Maple River <br />Aqueduct and Spillway being used by the physical modeling team. The Maple River overbank berms <br />near the structure will also be updated. Using the latest project designs, update the layouts and <br />inlet structure geometry for the Rush and Lower Rush Rivers, as well as Drain 30. <br />a. Update HEC‐RAS unsteady flow existing conditions and project conditions for the 10‐, 50‐, <br />100‐, and 500‐year Red River peak events. No diversion gate optimizations will be <br />conducted, as this will be completed as part of the Phase 8 model updates. <br />b. Update HEC‐RAS unsteady flow existing conditions and project conditions for the 10‐, 50‐, <br />100‐, and 500‐year Tributary peak events. No diversion gate optimizations will be <br />conducted, as this will be completed as part of the Phase 8 model updates. <br />Background: <br />The USACE, St. Paul District, is requesting Houston‐Moore Group’s (HMG’s) assistance in updating the <br />geometry for river, aqueduct, and drain inlet structures in the HEC‐RAS model as listed below in the Scope. <br />This model update work was not included in the Phase 7.1 model update, but should be done now so that <br />the HEC‐RAS model matches the Maple River Aqueduct numerical and physical models. <br />Cost = $ 25,000 <br />Recommendation: <br />PMC recommends authorization for Task Order No. 9, Amendment 10 for $ 25,000. <br /> <br />
