Deterioration of the walls has been hastened along by serious drainage problems and the back to back 100 year storms of 2 years ago that created the major washout. The lakeshore yard is currently in an unusable and unsafe condition. The new retaining wall systems will actually reduce the tiers of retaining walls within the lakeshore yard. The height of the wall is proposed at 2 feet to 8 feet exposed vertical height. Where the grade at the outside of the wall exceeds 30 inches in height rather than installing a railing per the building code, applicant proposes planter boxes. Positive drainage will be provided with drainage outlets at each side of the lakeshore yard. Note that the retaining wall tiers will be installed with grass. Surface runoff will run over grassed areas to the weep holes at east side and through a filter/trench system at the opposite end draining into a grassed retention area and finally to an existing urainage pipe at the north side of the lakeside yard. The applicant's landscape architect has laid out a system of lath and string line designating the location and height of the proposed wall for members of Council and Planning Commission who visit the site. A visit to this site is most important in order to not only understand the many exhibits submitted for this review but the full intent and purpose of this comprehensive repair project. The City Engineer has completed the majority of this review. Please review his comments and recoxunendation in Exhibit D. Additional Staff Comments Staff would recommend that the 240 square feet of the house addition that was approved with permit #4181 with an survey now be credited against the hardcover within the 75-250 foot setback area, resulting now in a slight excess of hardcover at a total of 13,344 sq ft (existing 13,134 + 240) or 25%. Applicant must be advised that any ocher improvements that require additional hardcover will require approval of the City.
