CITY OF ORONO <br /> PLANNING COMMISSION MEETING <br /> Monday,May 15,2017 <br /> 6:30 o'clock p.m. <br /> We recommend that the applicant have the proposed improvements reviewed and approved by a licensed <br /> professional engineer to ensure that site specific conditions such as drainage area and soil conditions are <br /> adequately considered in the location, sizing, and installation of the proposed infrastructure." <br /> While Staff finds the restoration of the slope failure areas to be necessary and the intended finished <br /> product is consistent with the City's goals for natural looking shoreline,the applicant's plans appear to <br /> incorporate some"engineering solutions" which are not designed by an engineer. Staff recommends <br /> verification from a licensed engineer that the proposed solution will effectively stabilize the slope. <br /> Staff does recommend approval of the conditional use permit, but based on the City Code Section <br /> 78-1283 referenced in the Staff report and the City Engineer's comments, Staff also recommends the <br /> applicant provide a restoration plan designed and certified by a registered engineer. <br /> The Planning Commission had no questions for Staff. <br /> John Baily, Applicant, stated the plan has been pretty well laid out and that he has put together a very <br /> capable team on this project. Ron Anderson has done a lot of these steep slope repairs around the lake, <br /> including the Wayzata Muni. Tom Niccum is also working with the team and he will be performing the <br /> riprap at the bottom of the slope. Norling Landscaping will be doing the planting. <br /> Bailey distributed some photographs of other projects completed by Ron Anderson. Some of the other <br /> projects completed by Ron Anderson include Howard's Point, which included a sewer pipe and a 50-foot <br /> high steep slope; and the Coffey Bridge. Bailey noted both of those projects were very difficult but the <br /> completed work was successful. <br /> Bailey stated in 2014, the area experienced a heavy rainfall and it washed out a portion of the slope, <br /> which has since been stabilized. The first washout occurred in June of 2014, which was followed by <br /> another rainfall that caused two additional washouts, including one of the adjacent property. <br /> Bailey stated as a result, he attempted to get an engineering solution to the problem. In order to engineer <br /> a solution, they would have to cut the slope back, which is very expensive and would require pilings. <br /> Bailey stated that engineering solution was not practical and that he continued to pursue a solution by <br /> looking at other areas along the shore that had washed out in the past. Bailey indicated that then led him <br /> to Ron Anderson, who designed this approach. Baily stated based on his experience, the repairs will work <br /> rather than having to do a whole re-grading of the shoreline. <br /> Bailey noted this is a residence and that a commercial building will not be built on this lot. Bailey <br /> commented his proposed solution is better than what currently exists and that it will not be possible to <br /> obtain an engineer's signature on his plan unless they cut the slope way back and obtain a 1:1 slope. <br /> Thiesse stated his main concern is with regards to the Filtrex,which says that it should be a 2:1 slope. <br /> Thiesse noted he would need further information on the Filtrex. <br /> Ron Anderson, Final Grade, Incorporated, noted the Filtrex is used in the early stages until the plantings <br /> are established. Anderson indicated Filtrex was used on the Wayzata Old Muni site and that they <br /> successfully completed that project approximately five years ago. This project proposes an eight inch <br /> thick Filtrex, which is a little deeper and stronger and steel rods can be run into it if necessary. Anderson <br /> noted they are unsure how much they will have to excavate on that slope to get it to be stable. <br /> Page 14 of 23 <br />
