There are three basic options for addressing the problem with many variations of each option. The first would be to leave the walls in place and camouflage them with bushes and shrubs as proposed by Janes Robin. The second would be. to modify the walls leaving sections in place to stabilize the bank. The area would then be graded and ground cover established to restore the bank. The third would be to remove the walls entirely and restore e a to its original condition. Option one is not consistent with previous city approvals. The proposal is structurally sound but does not provide the lake shore continuity desired by the City. Option two would leave the lower lake shore wall exposed and the upper two walls would be buried. The wall sections would continue to provide stability for the bank but wall exposure would be reduced by 60 percent. We have indi- cated the amount of wall to be removed on the attached drawing. • Page 1. 24 Page 6 of 8 2335 West Highway 36 • St. Paul, Minnesota 55113 • 612-636-4600 Otto G. Bonestroo. P.E. Keith A.

The lake shore . has been altered by the construction of several retaining walls. We do not know what condition the lake shore bank was in prior to construc- • tion. We did review the site several years ago with the previous owner and the lake shore bank appeared stable. The retaining wall construction will stabilize the bank and minimize the po- tential for future slope failure. The construction, however, is not consist- ent with City approvals on other applications. There are three basic options for addressing the problem with many variations of each option. The first would be to leave the walls in place and camouflage them with bushes and shrubs as proposed by Janes Robin. The second would be. to modify the walls leaving sections in place to stabilize the bank. The area would then be graded and ground cover established to restore the bank.
