<br />
<br />DISCUSSION:
<br />For subtasks that have been completed and have budget remaining, that budget was reallocated to tasks that
<br />remain open. There were minor budget overruns (less than $1,000) for subtasks F.I, F.III, and F.VIII.
<br />
<br />Additional costs of $68,184 for meetings and consulting were incurred to support the USACE Maple River
<br />Aqueduct Physical Model.
<br />
<br />Additional scope and budget ($350,493) are requested to complete the Phase 8 modeling task. Work includes:
<br />revising the Phase 8 model to match the Hickson Hydrograph and recalibrate the model, evaluation of RRN
<br />tributary hydrographs, address outstanding review comments, review and incorporate Western Cass Flood
<br />Insurance Study geometry and hydrology, compare Phase 8 model to Phase 7.1 model, and perform QA/QC
<br />reviews.
<br />
<br />Additional scope and budget ($27,537) is requested to support the update (expanded geography) of the NDSU
<br />Agricultural Impacts Study.
