• • #05-3135 December 6,2006 Page 2 Staff Comments on Revised Layout Building Height The revised survey/site plan has the southwesterly wing of the house abutting the existing grade approximately at elevation 938.5',with a lower floor level continuing to be proposed at 935.2' as it has been since the earlier reviews, which appears to be within a foot of the existing house lowest floor elevation. Based on this, it is staffs opinion that the proposed fill is not contributing to any unusual increased"visibility of structures...as viewed from public waters",one of the criteria for CUP analysis in Zoning Code Section 78-1250. Assuming no changes from the house elevation plans reviewed previously, the top-of-parapet elevation of 967' yields a defined building height of 28.5 feet,meeting the 30' limit. As before,the west yard will be filled so that only the upper level will be above final grade on that side. Grading and Drainage. The revised grading plan dated 11-30-06 has been reviewed by the City Engineer's office and their comments are summarized as follows: 1) Retaining walls for garage entrance need engineered design. 2) Drainage easement proposed over neighbor's property must be formally established. 3) Grading plan along south lot line keeps grading on applicants property and maintains height of existing boulder retaining wall. 4) Final grading plan should contain erosion and sediment control information. The applicant will be required to satisfy the Engineer's concerns. Additionally the resolution has been drafted to require the incorporation of rain gardens as a method of stormwater runoff treatment,per the Planning Commission recommendation. The resolution requires that the proposed drainage easement over the adjacent property at 3155 North Shore Drive must be granted and recorded with Hennepin County prior to issuance of a building permit for the new residence. Finally,because the access to the property is over a private easement roadway shared by a number of adjoining property owners, the applicant is advised to obtain whatever permission or approval is necessary from the entity that controls the road;2400 cubic yards of fill translates to 240 dump truck loads, which may have negative impacts from a traffic, noise, and road maintenance/repair standpoint. Staff Recommendation Staff recommends approval of the fill CUP, subject to compliance with the City Engineer's recommendations and comments. COUNCIL ACTION REQUESTED Adopt or amend the attached resolution.
