Zoning Pile #1046 July 18, 1986 Page 2 of 2 of hardcover in the 0—75' zone. We normally allow a maximum 4*x4* landing if it is 100% hardcover for lakeshore stairs such as these. There is a concern that the stairway and upper landing will be over the existing drainfield lines. We know that the general location of the drainfield lines is downhill from the house and running across the slope, but we don't know how deep or how long they are. The house was built on this 9,700 s.f. lot (0.22 acre) in 1972 with a variance. The existing drainfields are undoubtedly less than 75' from the lake and are currently working well with no visible seepage or discharge, but no possible way to replace the system other than a holding tank if future problems occur. Staff Recomendation - It appears that the proposed walls are intended for (and necessary for) either safety purposes or to preserve existing features such as trees and slopes. The slope is steep enough that a stairway is a reasonable request. Staff does not see the necessity of the two landings but would find them less objectionable if they are constructed with a permeable fill to minimize the hardcover. Approval might be conditioned upon: 1. Providing suitable erosion protection measures as required by City Inspector during construction. 2. Itairway construction to be at shallow depth only, to avoid conflict with drainfield lines. Strongly recommend no heavy equipment. 3. Since applicant has not provided an actual certificate of survey, and because this is adjacent to City fire lane and lake access, which has had encroachment problems before, a survey should be required in order to verify the lot lines and keep all improvements within the property boundaries. 4. Landscape crew to meet on the site with Inspector (Oman or Gaffron) prior to construction to attempt to verify drainfiled line location and depth. T/ts-c r 'O \ \
