<br />This is Task Order No. 9, Amendment 132, <br />consisting of 22 pages. <br />Houston-Moore Group, LLC Task Order No. 9, Amendment 132 <br />Hydrology And Hydraulic Modeling <br />In accordance with Paragraph 1.01 of the Agreement between Fargo-Moorhead Flood Diversion Authority <br />(“Owner”) and Houston-Moore Group, LLC (HMG) (“Engineer”) for Professional Services – Task Order Edition, <br />dated March 8, 2012 ("Agreement"), Owner and Engineer agree as follows: <br />The parties agree that in the event of a conflict between prior versions of this Task Order No. 9 and this <br />Amendment, the terms and conditions in this Amendment shall prevail, provided however, nothing herein shall <br />preclude ENGINEER from invoicing for work authorized under prior versions of this Task Order and performed prior <br />to effective date of this Amendment, even to the extent such prior work was revised by this Amendment. All other <br />terms and conditions shall remain the same and are hereby ratified and affirmed by the parties. <br /> <br />1. Specific Project Data <br />A. Title: HYDROLOGY AND HYDRAULIC MODELING <br />B. Description: Provide hydrology and hydrologic modeling services in order to advance design <br />components of the Diversion Channel. Specific modeling subtasks include: modeling of Diversion <br />inlets to determine design flows, modeling to evaluate hydraulic impacts of various Diversion <br />Channel sizes, extending model geometry of the Rush and Lower Rush Rivers, providing technical <br />assistance and support for the physical modeling of the Maple and Sheyenne River aqueduct <br />structures, and on-call services as requested. <br />2. Services of Engineer <br />A. HMS DIVERSION INLET MODELING: <br />The objective of this subtask is to develop an HMS model for each Diversion inlet subbasin using <br />synthetic rainfall events, and to obtain parameters for an estimate of discharge-frequency using <br />a methodology coordinated with the U.S. Army Corps of Engineers. <br />I. Discharge frequency curve at Amenia. <br />II. Adopted discharge frequencies at the inlet location after the initial HMS simulations. <br />Scope: <br />I. Model Diversion inlet inflows for 1.3-, 1.5-, and 2-yr rain events. Inlets to be modeled <br />are: <br />1. Diversion Inlet <br />2. Local Drain 1 <br />3. Drain 50 <br />4. Drain 21C <br />5. Local Drain 2 <br />6. Local Drain 3 <br />7. Local Drain 4 <br />8. Drain 14 (new location) <br />9. Original Drain 14 <br />10. Local Drain 5 <br />11. Maple River <br />12. Lower Rush River <br />HMG_TO9-A13_Long.docx 1 <br />DR <br />A <br />F <br />T <br /> <br />3/6 <br />/ <br />2 <br />0 <br />1 <br />5 <br />
