Zoning File #1549 June 22, 1990 Page 6 Additional Comments and Planning Commission Recommendations The Planning Commission had no concern with the variance phase of the application that would allow the screened enclosure of the patio area beneath the second story deck and accepted staff’s findings. The second phase of the application involves a conditional use permit to create a new access drive providing a loop roadway from the County road. The additional hardcover created by the new access drive is offset with the removal of existing gravel areas within the street yard and some 460 s.f. of plastic underliner area adjacent to the existing house. The applicant has submitted a revised grading plan based on Glenn Cook's review comments {Exhibit L). A 9-10' high wall has been replaced with a 2-tiered wall minimizing the visual impact from the lake. The maximum height of the highest section of the 2-tier wall is 4-1/2 to 5'. The slopes to the new driveway are at a 6:1 ratio parallel to the street and along the side at a 3:1 ratio. All drainage continues to flow through the property down to the lake. Prior to the City issuing building permits for the retaining walls as shown on the revised grading plans, the City must be in receipt of the Hennepin County permit approving land alterations and the retaining wall within the right-of-way of North Shore Drive. Staff has reviewed once again the hardcover calculations and notes the following changes: Allowed = 4,458 s.f. or 25% Existing = 5,132 s.f. or 28.7% Proposed in original plan = 4,359.5 s.f. or 24.3% Proposed based on staff's recalculations = 4,444.5 s.f. or 24.8% (Increase resulting from 85 s.f. of additional hardcover from retaining walls) The enclosed resolution has been drafted based on the approval of the variance that would allow the screened enclosure of the lower portion of a second story deck and conditional use permit that would allow 460+ cubic yards of fill to construct a new driveway access resulting in an overall reduction of hardcover within the 75-250' setback area of 3.9%.
