TO: City Council FROM: Michael P. Gaffron, Assistant Zoning Administrator DATE: June 4, 1995 SUBJECT: #910 James Hoff, 2056 Shadywood Road - Conditional Use Permit Zoning District - LR-lC Application - Regrade Lakeshore Yard of Property, All Within 0-75' Setback Area Existing Grade - Uniform Slope of to lake Proposed Grade - 24-30% slope List of Exhibits about 38% from high plateau down Exhibit A - Application Exhibit B - Plat Map Exhibit C - Property Owners List Ex' i_t D - Survey with existing and proposed contours Exi it E - Planning Commission Minutes 5-20-85 The applicant is requesting a conditional use permit to allow him to regrade the lakeshore of his property so that it conforms more to the properties on either side of him. Most of the work proposed is within the 0-75' setback area. His existing slope is about 38% according to the existing grade topographic submittal. The proposal would decrease the slope to about 25% on the -average, but would eliminate the flat plateau which currently acts as runoff percolation area. City Engineer, Glenn Cook, has reviewed the proposal and made these comments: 1. The proposed contours as shown do not accomplish the stated purpose of conforming to the neighboring property contours. Note that the property to the north has extensive retaining walls. How will the grading conform to these? On the south side, where slopes are less severe, it would likely require less removal of material to conform to the neighboring grades. 2. The proposed grade changes will eliminate the existing 30-40' "plateau" area of 6% slopes or less, which now functions as slow - runoff and infiltration area, and change the entire lakeshore yard to slopes of 24-30%. From a runoff infiltration standpoint, this is not necessarily a beneficial project. One-third of the lakeshore yard which formerly had relatively good infiltration characteristics will be reduced in infiltration capacity.
