Zonimj Administrator DATP.; SUBJECT May 17, 1985 #910 James Hoff, 2056 Shadywoed Road - Conditional Use Permit Zoning District - LR-IC Application -Regrade Lakeshore Yard of Property, All Within 0-75' Setback Area Existing Grade - Uniform Slope of about 38% from high plateau dewn to lake Proposed Grade - 24-30% slope List of Exhibits Exhibit A Exhibit B Exhibit C Exhibit D Application Plat Map Property Owners List Survey witii existing and proposed contours 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 averme, 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 pui pose of conforming to the neighl>oring property contours . Note tliat 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 vi11 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 i nfi11ration standpoint, this is not necessarily a beneficial project. One-third of the lakeshore yard which formerly had relatively good infiltration characteristics will be retluced in infiltration capacity. i
