(AP TO: FROM: DATE: SUBJ : _'I1 8 198 7 Mayor Grabek Orono Council Members City Administrator Bernhardson Jeanne A. Mabusth, Zoni.,q Administrator June 1, 1.987 #1103 Howard Ei_singer, 3245 Wayzata Blvd. - Conditional Use Permit - Resolution List of Exhibits - A - Braun Engineering Letter B - Council Notice of Action At Council's request, Mr. Eisinger's contractor, John Gannon has submitted the existing test data of 1974 to the original engineering firm that conducte(; the tests. Review Exhibit A, Braun Engineering states as follows: "it is our opinion that t►.•_ proposed addition of f .ve feet of r•ineral - 'I above the top of the existing landfill grades prese a very slight risk of shear failure." The following reasons are cited: 1. Past. experience with similar landfill sites situated within a wetland. 2. Existing landfill material probably possesses high internal angle of friction and a high shear strength based on existing conditions. 3. Settlement that has occurred over the past _ years will also increase the shear strength of the iApp.,r i zone of organic soils and will lessen risk of shear :A- m result of placing an additional surcharge load. Staff has met with both Eisin3er and Ganno-i to discuss the final preparatory steps required so that the permit at the 100,000 cubic yard level may be approved by Council. As Braun Engineering has suggested, we will ask that monitoring plates, minimum of 3, he placed along the edges of the fill area. Staff will be able to observe these plates upon inspections to determine if there is an abnormal rate of settlement. Staff has advised Gannon ,-hat the City will require a developer's agreement and appropriate security to insure that final grading and seeding will be completed even if the fill project as proposed is not. realized. The Engineer's recommendations regarding erosion control, inspect ion schedu 1 e .and mon i t or i ny f i l l Fero jest have a l so been referenced in this resoll,.ion.
