To: Orono Council Members From: Michael P. Gaffron, Assistant Zoning Administrator Date: October 24, 198'., Subject: #910 James Hoff, 2056 Shadywood Road - Conditional Use Permit List of Exhibits Exhibit A - Staff Memo of 6/4/85 Exhibit B - Revised Survey and Soil Boring Results Exhibit C - Lands pe and Grading Plan Exhibit D - Pi ing Cummission Ming-L5 5/20/85 Exhibit E - C -il Minutes 6/10/85 This item was tabled at yc,ur June 10, 1985 meeting in order to allow the applicant an opportunity to provide additional supportive data regarding his request to regrade portions of his lakeshcre yard. The applicant has submitted a report of soil borings performed by Mark Gronberg which indicates that near the center of the lot at the crust of the slope, up to 3' of fill was placed at some previous date. A landscape plan by Lan -De -Con Inc. has been submitted which indicates that the only area to be regraded will be the sharp crest of the hill, or a strip approximately 35' wide across the lot, and showing no grading closer. than 35' to the shoreline. The estimated maximum cut area is 3' deep at the crest. Note also that the landscape plan indicates the placement of new trees and shrubbery where none exists now. The proposed stairway with wood chip platforms will replace the existing 27" wide stairway. Using a porous weed mat below the chips, theme is no resultant in- crease in the minimal (1.5%) existing 0-75' hardcover. This revised plan appears to be less extensive than the original plan and disrupts a much smaller area of yard than was originally proposed. Silt mats to prevent sediment from entering the lake can be placed about halfway up the slope �0' hack from the lake. Staff would anticipate no erosion problems with this new plan 3s long as proper practices are adhered to. As the Councilmembers stated in June, an engineering case could be made on both sides of the issue of whether this project is a benefit from a run-off standpoint. City Engineer, Glenn took, has stated that the project will not be detrimental to the run-off situwtion. Finally, noting that lowering the steep slope will tend to make maintenance of the grassed siope less hazardous, staff submits a draft resolution of approval for your review, incorporating findinqs and conditions pertinent to the project..
