The <br /> revised plan proposes to remove an existing boat house and stabilize the disturbed shoreline with plantings.We <br /> have the following comments with regards to engineering matters: <br /> • The plans should include proposed erosion controls.All silt fence should be the heavy duty type with <br /> steel t-posts. <br /> • The previously submitted plan showed a swale to convey water to the lake along the south lot line.The <br /> revised plans should incorporate the same swale design to contain storm water on the subject property. <br /> • The plans should identify the proposed trail surfacing material. <br /> • The plans should clarify where the 3-inches of hardwood mulch will be placed. <br /> • All erosion control measures should be inspected and approved by the city prior to any work on site. <br /> The erosion control should be maintained and remain in place until the vegetation is established and <br /> the slopes are stabilized. <br /> If you have any questions please call me at(651) 604-4863. <br /> Yours very truly, <br /> BONESTROO, ROSENE, ANDERLIK&ASSOCIATES, iNC. <br /> �47�rj <br /> 'Tom Kellogg <br /> Cc: Greg Gappa, City of Orono <br /> ■ St. Paul, St. Cloud, Rochester, Willmar, MN ■ Milwaukee, WI • Chicago, IL <br /> Affirmative Ac[ion/Equal Opportunity Employer and Employee Owned <br />
