Those areas were defined as eroding bank adjacent to boathouse and erosion near stone walk adjacent to southern lot line. Staff met with applicant and applicant's consultant in late sximmer. The revised plan proposes retaining walls lim’^ed to two sections with one running approximately a total of 58* parallel to the lake a id continuing eastward along the access stairs. The second sec. on will be placed along the south lot line at approximately a 3 to 3 1/2' I Igh height for 25 +'. Please review Exhibit B. Per Planning Commission's original directive, the applicant seeks approval for replacement of access stairs within 0-75' setback area at a 3' width. Staff has been advised they will be grade level cement pads supported and surrounded by timbers . The applicant proposes the same design for the retaining wall construction and has once again submitted the same cross section. The walls adjacent to the boat house will be at approximately a 4 to 4 1/2' height. In regard to the upper wall. Cook cautions that the wall may channelize the water and erosion problems may result. Applicant should be placed on notice that he would be expected to maintain the repair of this retaining wall in order to insure against any negative impr^t on the lake. In Cook's report he asks that a typical section of the wall should be strengthened by including a lower row of deadmen offset from the top row at 8' on center. Applicant is required to provide erosion control fence between the work areas on the lake. Erosion control must be installed prior to any land alteration. L
