This is Task Order No. 8, Amendment 910, consisting of 14 pages. Houston-Moore Group, LLC Task Order No. 8, Amendment 910 Work-In-Kind (WIK) In accordance with Paragraph 1.01 of the Agreement between Fargo-Moorhead Flood Diversion Authority (“Owner”) and Houston-Moore Group, LLC (HMG) (“Engineer”) for Professional Services – Task Order Edition, dated March 8, 2012 ("Agreement"), Owner and Engineer agree as follows: The parties agree that in the event of a conflict between prior versions of this Task Order No. 8 and this Amendment, the terms and conditions in this Amendment shall prevail, provided however, nothing herein shall preclude ENGINEER from invoicing for work authorized under prior versions of this Task Order and performed prior to effective date of this Amendment, even to the extent such prior work was revised by this Amendment. All other terms and conditions shall remain the same and are hereby ratified and affirmed by the parties. 1. Specific Project Data A. Title: Work-In-Kind (WIK) B. Description: This task order will include requests by USACE for the Local Sponsor (Diversion Authority) to provide WIK services related to the Project. C. Background: As allowed by the Federal process, USACE is allowed to request the Diversion Authority provide services as WIK for services that USACE would normally do, but that the Diversion Authority has resources or particular expertise to perform. 2. Services of Engineer A. MEANDER BELT WIDTH ANALYSES: Background: Meander Belt Width Analysis was begun under a separate contract. This scope expands upon the work completed under the separate contract. Develop a Technical Memorandum (TM) that provides estimates of the probability of non- exceedance for different meander belt widths given design flows and channel geometry of the Low Flow Channel (LFC), variability and uncertainty in the erodibility and shear strength of the soils along the LFC, and most likely scenarios for the sequence of diversion works commissioning. Develop for the following six (6) reaches: I. Diversion outlet upstream to Rush River inlet II. Rush River inlet upstream to Lower Rush River inlet III. Lower Rush River inlet upstream to Maple River aqueduct IV. Maple River aqueduct upstream to Drain 14 inlet V. Drain 14 inlet upstream to Drain 21C inlet VI. Drain 21C inlet upstream to Sheyenne River aqueduct Conduct the following tasks: I. Site visit of Red River and tributaries. II. Conduct geoprobe drilling, sediment coring, and carbon dating at transects along successive point bars in meander loops at the Red River of the North, Sheyenne River, and Rush River (upstream of channelized reaches) to determine channel migration rates over geologic time scale.
