The lake shore <br />has been altered by the construction of several retaining walls. <br />We do not know what condition the lake shore bank was in prior to construc- <br />tion. Ve did review the site several years ago with the previous owner and <br />the lak, .hore bank appeared stable. <br />The retaining wall construction will stabilize the bank and minimize the po- <br />tential for future slope failure. The construction, however, is not consist- <br />ent with City approvals on other applications. <br />There are three basic options for addressing the problem with many variations <br />of Each option. The first would be to leave the walls in place and camouflage <br />them with bushes and shrubs as proposed by Janes Robin. The second would be <br />to modiy the walls le sections in place to stabilize &he bank. The area_ <br />would then be graded and ground cover established restore the bank. The <br />third would be to remove the walls entirely and restore e a to its <br />original condition. <br />Option one is not consistent with previous city approvals. The proposal is <br />structurally sound but does not provide the lake shore continuity desired by <br />the City. <br />Option two would leave the lover lake shore wall exposed and the upper two <br />walls would be buried. The wall sections would continue to provide stability <br />for the bank but wall exposure would be reduced by 60 percent. We have indi- <br />cated the amount of wall to be removed on the attached drawing. <br />Page 1. <br />24 <br />Page 6 of 8 <br />2335 West Highway 36 • St. Paul, Minnesota 55113 • 612-636-4600 <br />
