i TO:Mayor Callahan and Orono Council Members Ron Moorsc. Cirv Administrator UNOL METING FROM:Jeanne A. Mabusth. Building & Zoning Administrator MAY 1 0 1993 CITY OF (MONO DATE:May 5. 1993 SUBJECT: #1818 Russell Lund Estate, 905 Tonkawa Road - Class III Preliminary Subdivision • Resolution Brief Reekw of Application and Planning Commission Recommendation The application involves tlw two lot division of the 6.3 acre Lund Estate. Each lot well exceeds the LR-1B area and lot width standards. The storage shed located at the proposed division line ^hall be removed. The developed lot has excessive hardcover within the 250-500* setback area within an 11.8% excess over the allowed 30%. There is 5.3% hardcover within the 0-75’ setback area consisting of a small deck, sandbox and 10’ + wide concrete and asphalt ramp. The Planning Commission discussed the issue as to whether additional area should be provided to offset the excessive hardcover in the 250-500’ setback area or require removals. Members also noted that if additional area is taken within the 250-500’ setback area to support existing hardcover this would encourage residential construction closer to the lake which would also necessitate an average lakeshore setback variance approval. The Planning Commission opted to allow the hardcover to remain with an 11.8% hardcover variance but asked that the asphalt ramp within the 0-75’ and 75-250’ setback areas be removed as a condition of the preliminary subdivision approval. In recent conversations with representatives of the estate, the applicants agreed to remove the asphalt ramp but voiced concern that there is still a need to provide access suirs down the embankment control erosion once the area is disturbed. Staff reinspected the lakeshore area and concurs that because of the existing topography there will be a great potential for erosion. In the early development of this properly, the lakeshore bank was altered to provide access to the shoreline. The excavated area now carries major surface water drainage from the upper elevations to the lake. Special care must be given to the i^esign of any structure being placed within the existing ramp area. Applicants have been advised to submit a plan addressing both an access structure and erosion control prior to final plat approval. Applicants shall also provide final hardcover facts for amended proposal. Other conditions of approval dealt with removal of the tower/antenna structures and on the property as original conditional use permit expires with the creation of new lot lines. Staff was to review the base of the tower located within the kennel strucuire. Staff recommends that six anchor bolts be removed to the level of the cement floor of kennel. /
