Therefore, <br />the lake excavation will be completed this winter. The procedure will be similar to last year. <br /> <br />1. The temporarily dewatering of Mirror Lake (DNR PWI No. 62-198M) will begin September 13, <br />2017 <br />a. In accordance to Minnesota Statues 103G.408, a public hearing will be held during the <br />City Council meeting scheduled for 7:00 p.m., Tuesday, September 12, 2017, at the St. <br />Anthony Village City Hall, 3301 Silver Lake Road. <br />b. The dewatering begins in September to allow for amphibians and other animals to find <br />alternative homes during the construction. <br />2. Pumping of the lake will begin once consistent freezing temperatures have arrived. <br />a. The water is removed to freeze the soils on the bottom of the lake. This will allow heavy <br />construction equipment to traverse the lake without getting suck in the muck. <br />3. During the beginning of the winter the contractor may need to move the snow on top of the lake. <br />Snow insulates the soil, slowing and reducing the frost layer. <br />4. The excavation will be completed once the soils in the lake bottom are frozen deep enough for <br />large tucks to travers without getting stuck. <br />5. The Lake’s outlet control structure will be replaced once the excavation is complete. <br />6. The flood berm will be “roughed in” once the outlet structure is in place. <br />7. Final grading, restoration of the access point, and berm will be competed in the spring once the <br />soils have dried to allow for better workability. <br /> <br />Many of the above tasks are weather dependent; therefore, exact start and stop dates are challenging to <br />predict. We appreciate your patience during this construction process. If you have any questions or <br />comments related to this project, please contact Tony Miller at 612-554-6974 or tmiller@wsbeng.com. <br /> <br />Sincerely, <br /> <br /> <br /> <br />Todd Hubmer, PE <br />City Engineer <br /> <br />Cc: Mark Casey, City of St. Anthony Village Jay Hartman, City of St. Anthony Village <br /> Jeremy Gumke, City of St. Anthony Village Craig Schlichting, City of New Brighton <br /> Tony Miller, WSB & Associates, Inc.
