The deck was constructed over a series of retaining walls that protect the lake <br />shore bank. The bank failed during the big storm of 1987. <br />We would recommend that a majority of the deck be removed. The cross hatched area would <br />indicate the stairway and deck that could remain in place. The retaining walls will have to be <br />modified because they do not appear to be stable in all cases without the overlying deck. The <br />owner should be required to provide a new plan with the modified retaining walls and proposed <br />deck and stairway area. <br />Please contact this office if you have any questions. <br />Yours very truly, <br />BONESTROO, ROSENE, ANDERLIK & ASSOCIATES, INC. <br />4~((_4 <br />Glenn R.
