MINUTES OF THE ORONO CITY COUNCIL MEETING November 10, 2014 7:00 o’clock p.m. _____________________________________________________________________________________ Page 6 of 31 (4. #14-3669 MARK AND KRISTEN ANDERSON, 3850 WATERTOWN ROAD – REVISED GRADING CONDITIONAL USE PERMIT PLAN, Continued) one of the stipulations the MPCA requires and the main issue in that area was the collapsed drain tile. In the 1970s or 1960s, the adjacent property owner had installed the drain tile and it has since deteriorated and collapsed. Anderson stated for the last two springs, it has been very wet and the water level has been increasing. Levang asked if it is correct that the original conditional use permit was for 10,000 cubic yards and now it will be closer to 20,000 cubic yards. Curtis indicated that is correct. Anderson stated that is because the pasture area has doubled in size. David Bade, Westwood Professional Services, stated he has been retained by the Hedbergs to provide an independent third party analysis on some of the compliance issues and some of the activities that have been happening since this project started. Bade noted he has prepared a memo that was submitted to the City earlier today. Bade stated the main concerns are the potential impacts to the Hedberg property based on the grading activities, specifically the extent of the grading in the outflow area. Bade stated the proposed grading plan may potentially impact the low lying areas and that there are structures in fairly close proximity to the wetlands. Bade indicated he will need more information to complete a drainage analysis to determine what has been done to the drain tile. McMillan asked if the Hedbergs have ever had the wetland delineated on their property. Bade stated he does not believe there is a wetland on their property. McMillan stated since the City Council just received his memorandum tonight, it may be necessary for the City Council to take it under advisement. Bade stated the main concern at this point in time is the expansion of the project and the berm. Bade stated those areas will provide less overall capacity in the low lying area and that the concern during large storm events is where the water will go. Bade stated based on the plan, in his view the likely path of the drainage could impact the Hedberg’s property. Anderson stated the yellow area is where some of the recovered top soil is stockpiled. The elevation in that area is supposed to go back to the original elevation. Anderson stated the area where there are no lines in the delineated area, all of that will drain now because the drain tile has been fixed, and that there should not be overflow occurring onto the other property. Bade stated they would request an actual drainage analysis be performed by a licensed professional engineer. Bade noted this proposed grading plan has come out just within the last few days and that they do not know what the impact will be in the spring.
