CITY OF ORONO PLANNING COMMISSION MEETING Monday, May 15,2017 6:30 o'clock p.m. We recommend that the applicant have the proposed improvements reviewed and approved by a licensed professional engineer to ensure that site specific conditions such as drainage area and soil conditions are adequately considered in the location, sizing, and installation of the proposed infrastructure." While Staff finds the restoration of the slope failure areas to be necessary and the intended finished product is consistent with the City's goals for natural looking shoreline, the applicant's plans appear to incorporate some "engineering solutions" which are not designed by an engineer. Staff recommends verification from a licensed engineer that the proposed solution will effectively stabilize the slope. Staff does recommend approval of the conditional use permit, but based on the City Code Section 78-1283 referenced in the Staff report and the City Engineer's comments, Staff also recommends the applicant provide a restoration plan designed and certified by a registered engineer. The Planning Commission had no questions for Staff. John Baily, Applicant, stated the plan has been pretty well laid out and that he has put together a very capable team on this project. Ron Anderson has done a lot of these steep slope repairs around the lake, including the Wayzata Muni. Tom Nickurn is also working with the team and he will be performing the riprap at the bottom of the slope. Norling Landscaping will be doing the planting. Bailey distributed some photographs of other projects completed by Ron Anderson. Some of the other projects completed by Ron Anderson include Howard's Point, which included a sewer pipe and a 50 -foot high steep slope; and the Coffey Bridge. Bailey noted both of those projects were very difficult but the completed work was successful. Bailey stated in 2014, the area experienced a heavy rainfall and it washed out a portion of the slope, which has since been stabilized. The first washout occurred in June of 2014, which was followed by another rainfall that caused two additional washouts, including one of the adjacent property. Bailey stated as a result, he attempted to get an engineering solution to the problem. In order to engineer a solution, they would have to cut the slope back, which is very expensive and would require pilings. Bailey stated that engineering solution was not practical and that he continued to pursue a solution by
