Of DEPARTMENT OF THE ARMY <br />ST PAUL DISTRICT. CORPS OF ENGlf«ERS <br />ar »«v corps of engineers centre <br />190 fifth street east <br />ST. PAUUMN55I0MSM <br />January 26, 1996 <br />REPLY TO <br />ATTEimONOF <br />Construction-Operations <br />Regulatory (96-02049-NW-JJY) <br />Ms. Elizabeth McMillan <br />1275 Lyman Avenue <br />Wayzata, Minnesota 55391 <br />Dear Ms. McMillan; <br />We have reviewed the information you provided about your <br />proposal to excavate a small pond (about 6,00C sguare feeb, or <br />less than 0.15 acre, of wetland grading) and use the excavated <br />material to establish a more natural slope in an area where a <br />retaining wall collapsed. The excavation should also improve <br />wildlife habitat and remove purple loosestrife. The landscaped <br />area would be planted with native species. The project site is <br />in the NW 1/4 Sec. 2, T. 117 N., R. 23 W., City of Orono, <br />Hennepin County, Minnesota. <br />This work is authorized by the Department of the Army <br />nationwide permit referenced below and described in the <br />enclosures, provided the enclosed conditions are followed. <br />This determination covers only the project described above. <br />If the design, location, or purpose of the project changes, <br />contact us to make sure the work would not violate Federal law. <br />It is your responsibility to ensure that the work complies with <br />the terms of this letter and the enclosures, AND THAT YOU OBTAIN <br />ALL REQUIRED STATE AND LOCAL APPROVALS BEFORE YOU PROCEED. <br />The combination of native plantings and excavation may help <br />limit the growth of purple loosestrife in the pond. However, as <br />your consultants may have already informed you, purple <br />loosestrife produces many seeds and may spread quickly in the <br />disturbed areas around the open water pond and undo all your <br />careful planting efforts. Wetland soil excavated from the pond <br />may also spread loosestrife in areas where this soil is used as <br />topdressing. Hand removal of young loosestrife plants before <br />they go to seed may be the most effective method to control this <br />species, although spot spraying of approved wetland herbicides <br />may be necessary if hand removal is not sufficient. If you have <br />any questions, please contact Mr. Joseph Yanta at (612) 290-5362. <br />Sincerely, <br />-V5en Wopat\ \^ 'Ben Wopat \ <br />Chief, Regulatory Branch <br />Enclosures <br />Determination; 33 CFR 330 - Appendix A (26) <br />Pnni»d on ©RocvciaO Papof
