REQUEST FOR COUNCIL ACTION Date:August 11, 2014 Item No._� Department Approval: Administrator Approval: Agenda Section: Engineer Update Name: Andrew Mack,AI Title: Community Development Director Item Description: 3165 North Shore Drive-Review o sit ling&grading work List of Exhibits: A. City of Orono Resolution#6315 Approving CUP Planning Case#13-3624 B. Amended Grading Plan Received 8/1/14 C. 8/4/14 Letter from David Martini D. 4/5/14 Memo from Mark Gronberg Proiect Backaround: On 8/26/13 the council approved a CUP for filling and grading work on the subject property(please see attached resolution). The approval specifically authorized a total of 2,267 cubic yards of fill material on this lake front lot with conditions including an optional review by the Planning Commission and Council as may be needed and required conformity with the requirements of the city engineer. Extensive history preceded this work including demolition of a dwelling,approval of a building permit for a new home that was never completed,and a CUP for the site fills and grading work in 2009 which was never completed. Proiect Status: Planning& Engineering staff have worked closely with the contractors and adjoining property owners in efforts to minimize adverse impacts and monitor the work of a protracted site grading and riparian lot restoration project on the subject property. Following extensive review of the work being conducted this spring&summer, and based upon a determination made by both the city's consulting engineer,grading contractor,and the land owner's engineer; changes were made to the approved grading plan while the work was being completed in the past 2 weeks(please see attached revised grading plan). Dave Martini prepared the attached letter authorizing the changes to the plan.The site grading work is now complete and the contractor will be hydro seeding the site to re-establish turf for the disturbed land area. The revised calculation of fill materials according to the land owner's engineer is 3,800 cubic yards(please see attached e- mail from Mark Gronberg). This was an increase of 1,533 cubic yards,or approximately 68�above the original plan. The reason for the increase was due to the removal of an existing garage and retaining wall at the west end of the site thereby allowing for a much more gradual slope of the lot, required redirecting of drainage away from the adjacent residence to the east down the center of the lot toward the lake,and for greater ease of lawn maintenance without the severe slopes. Proiect Review: Due to the changes in the amount of fills,and given the on-going nature of concerns associated with the work on this site, staff felt it would be appropriate to provide council with an update of this project. It will be provided by the city's consulting engineer and we will both be prepared to answer any questions the council may have.
