Information for File #MVP-2015-00431-LMG Applicant: Shakopee Mdewakanton Sioux Community Corps Contact: LeeAnn Glomski Address: 180 Fifth Street East, Suite 700, St. Paul, Minnesota 55101-1678 E-Mail: [email protected] Phone: (651) 290-5324 Sections: 21 and 22 Township: 115N Range: 22W Information Complete On: November 2, 2015 Posting Expires On: November 12, 2015 Authorization Type: LOP-05-MN This application is being reviewed in accordance with current practices for documenting Corps jurisdiction under Section(s) 9 & 10 of the Rivers and Harbor Act of 1899 and Section 404 of the Clean Water Act. We have made a preliminary determination that the aquatic resources that would be impacted by the proposed project are subject to Corps of Engineers jurisdiction under Section(s) 9 & 10 of the Rivers and Harbors Act of 1899 and/or Section 404 of the Clean Water Act. If an approved jurisdictional determination is completed as part of the review process for this application, a copy will be posted on the St. Paul District web page at the following link: http://www.mvp.usace.army.mil/Missions/Regulatory.aspx. Project Description

The Shakopee Mdewakanton Sioux Community proposes to discharge dredged and fill material into 0.08 acre of wet meadow (type 2) wetland. The proposed project would also temporarily impact 0.02 acre of fresh meadow. The work will be conducted in association with the construction of an earthen dike with a water control structure to attenuate high water flows from upstream development. Attenuating high water flows and releasing water slowly will reduce downstream channel incising. As a result of the dike construction, 0.77 acre of existing wetlands will retain a higher water elevation. Federally Listed Threatened and Endangered Species According to the USFWS Midwest Region website, which was checked on October 29, 2015, the Northern long-eared bat (threatened) is found in Scott County, Minnesota.

Historic Properties The latest version of the National Register of Historic Places has been consulted and no listed properties (known to be eligible for inclusion, or included in the Register) are located in the project area. State Listed Impaired (Section 303(d)) Waters According to the Minnesota Pollution Control Agency’s Impaired Waters Viewer, which was checked on October 29, 2015, there are no state listed impaired waters located within 1-mile of the project area.
