The plan <br />provides for approximately 75 feet of retaining wall on the property. Approximately 65 feet of <br />the wall will be located in the 0-75’ setback area. <br />The section of wall (25’±) ne.xt to the boathouse is necessary to prevent failure of the bank and <br />protect the boathouse. Tlte remaining sections are to reduce mainteiiance problems in the yard. <br />The typical section for the wall should be strengthened by including a lower row of dcadmen <br />as shown^ offset from the top row at 8 ’ on center. <br />The property owner should be required to provide erosion control tence between the work areas <br />and the lake. The upper wall could channelize the water and erosion problems would result. <br />The owners will be required to repair these areas and continue to protect the lake as necessary <br />after the work is completed. <br />Please contact this office if you have any questions, <br />Yours verv trulyjr <br />BONESl'ROO, ROSENE, ANDERLIK & ASSOCIATES, INC. <br />Glenn R.
