    The U.S. Army Corps of Engineers, Omaha District (Corps), is evaluating a permit application submitted by South Dakota Department of Transportation (SDDOT) to construct the South Veterans Parkway including improvements to nine intersecting City Arterials. Proposed construction of Phase III of the project between Cliff and Sycamore Avenues would result in the discharge of approximately 49,368 cubic yards of fill material into 13.36 acres of waters of the United States, including wetlands, adjacent to unnamed tributaries and Spring Creek. The SDDOT and City of Sioux Falls (City), in coordination with the Federal Highway Administration (FHWA), is proposing to construct South Veterans Parkway which would complete the 17-mile limited-access regional arterial roadway between I-29 (Exit 73) and I-90 in Sioux Falls, South Dakota. South Veterans Parkway would consist of approximately 8.5 miles of limited access arterial roadway between I-29 (Exit 73) to just north of 57th Street. The City is planning to construct nine City arterial roadway projects that intersect with the proposed South Veterans Parkway. The City arterials have been planned to be constructed simultaneously with South Veterans Parkway to improve efficiency and reduce the duration of road closures to the traveling public.

    The Sponsor (Westervelt Ecological Services) is proposing to develop a compensatory mitigation site within the Bad/Cheyenne/Belle Fourche Geographic Service Area (GSA). If approved, the Mitigation Site would produce credits available to offset the loss of waters of the United States within the GSA. The Sponsor proposes to restore an intermittent stream channel and adjacent wetlands.
