i Zoning Pile i<^1838 June IS, 1993 Page 2 sustained severe erosion. The repairs involved rip rapping at the shoreline area and the installation of geo-grid fabric with supposedly a support sub-structure similar to the recent Susan Sumey proposal. As it was the e.xpress desire of the applicant to achieve a permanent solution with the current improvement proposal, the City Pngineer i.as recommended a concrete modular block retaining wall. Review E.xhibit E. The applicant proposes the installation of an Allan Block Retaining Wall that will be installed in two tiers. The highest wall will be 4 ’. Applicant will install 3:1 sloped land areas to allow for easy maintenance and installation of plantings tor the purpose of achieving immediate ground cover for stabilization of disturbed areas. Review E.xhibii J. It is not clear whether the current proposal involving a modular block wall will cover the same area proposed in the original landscaping design that involved timber wall construction.

The City Engineer will provide a report for your Monday meeting reviewing tinal intormation. Members may question staff as to the review of an application where we have not received complete information. Unfortunately, Mr. Owens had not realized that he would have to proceed with another conditional use permit application alter receiving approvals to restore his lakeshore banks in 1987 and 1988. Stalfhas proceeded with the review of this application as there is an immediate need to act swiftly because the collapse of the bank not only involves a small portion but as applicant’s addendum notes, A-1, there is a tension crack running parallel with the crest of the slope that indicates potential for complete failure. Upon your inspection, you will note that a plastic sheet witli temporary anchors has been placed along the bank to prevent further undermining by runoff, but with this rainy late spring applicant is concerned that time is running out. In your final recommendation, the following should be included in your conditions of approval: 1. Erosion control to be maintained on property before any land alterations commence :md to be maintained until ground cover is restored. To be consistent with similar applications in the past, applicant is to provide a landscape schedule for plantings that will shield the block walls from the lakeside view and that ground cover be immediately restored within all disturbed areas.
