<br />HMG_TO08-A13_Long 10 <br />dynamic equilibrium generally exhibit some erosion and ongoing changes that <br />are considered baseline or normal responses to various driving mechanisms. <br />The Army Corps of Engineers and partners acknowledge that post construction <br />changes to the river systems may occur and are cooperatively creating a <br />monitoring plan and adaptive management guidelines to measure, evaluate, <br />and respond to changes. Relative impacts of the Project on the river channel <br />and associated resources will largely be based on assessments and <br />comparisons of stream bank conditions over time. Monitoring the river(s) <br />before and after construction provides the necessary empirical data for a valid <br />assessment of the impacts that can be attributed to the Project. <br />3. Location: Red River and associated tributaries in the Fargo, ND and Moorhead, <br />MN Project area. Tributaries include Wolverton Creek, Wild Rice River (ND), <br />Buffalo River, Sheyenne River, Maple River, Rush River and Lower Rush River. <br />4. Deliverables: <br />a. Compile channel erosion and deposition data and graphics from <br />existing reports into one file location and summary document. <br />b. Provide aerial photographs, shapefiles and attributes for all stream <br />bank erosion and depositional features for defined rivers and creeks <br />including: <br />i. Location <br />ii. Feature identification (e.g., bridge scour, overbank <br />deposition) <br />iii. Length, height, area, and estimated volume of erosion or <br />deposition <br />1. Determine existing bank heights from LIDAR and <br />estimate erosion/deposition volumes based on the <br />LIDAR elevations, complemented by river cross <br />sections or bathymetric information that can be <br />available. <br />iv. Hypothesis about possible driver of feature (natural <br />meandering process, artificial structure, land use change, <br />surficial drainage pattern change, etc.) <br />v. Percentage of each river reach (as defined in the <br />geomorphology study by WEST Consultants, also shown in <br />Exhibit “A”) and the overall system that each feature type <br />represents <br />vi. Percent change of each feature at each location for 3 to <br />4 data points over evaluation period <br />vii. Graphic and tabular data of changes from 1980’s to present <br />day <br />1. GIS layer with erosion and depositional features <br />highlighted and linked to data attributes listed <br />above. DRAFT
