Memorandum <br />Date: 4/5/10 <br />To: Jeremy Barnhart <br />From: John Anderson <br />RE: Kostreba Mini Storage Expansion <br />.^ <br />BDM <br />CO1`SBL'l7NG ENGP~EERS AAiD SLIRt~EYORS; PLC <br />60 Plato Boulevard East: Suite 140 <br />St. Paul, MN 55107 <br />763-786-4570, Fax 763-786-4574 <br />I have reviewed the sketch provided for the Kostreba Mini Storage Expansion. I met on site <br />with Russell Kostreba to look at the erosion area. Mr. Kostreba said that he is concerned <br />about ability to access to the property where the storm water pond is located in order to do any <br />work to repair erosion. I found the erosion of the pond is as described by Mr. Kostreba. The <br />eroded area is approximately 2 to 3 feet wide and 9 to 18 inches deep. The eroded slope of the <br />pond is on the south end of the pond and along the path where the surface drainage from the <br />Mini Storage site enters the pond. <br />The proposed expansion of the Mini storage site will increase run off to the pond and add flow <br />to the area where the erosion has developed. Given these conditions 1t is necessary to repair <br />the erosion in conjunction with the expansion of the mini storage site. The plan for the mini <br />storage site should be amended to include work to restore the south slope of the pond. <br />BDM Project # <br />
