The plans are dated 12-29-11. We <br /> have the following comments with regards to engineering matters: <br /> • The proposed retaining wall between the house and pool area is shown as 4.0 feet in height. If field <br /> changes increase the height, engineering design and details must be submitted for review. <br /> • The slopes near all backyard retaining walls exceed the maximum of 3:1. Revisions to the grading or <br /> retaining walls should be made and resubmitted. <br /> • Drainage patterns at Graham Hill Road should be addressed. The installation of a culvert at the north <br /> driveway leg appears necessary. Drainage patterns should be shown near the south driveway leg to <br /> determine if a culvert is required. <br /> • This project will disturb more than 100 CY of material. Sediment and erosion control information <br /> meeting the requirements of Orono's City Code 79-7(c)(2) must be submitted. The minimum $2000 <br /> sediment and erosion control financial security should be required of the owner for this permit. <br /> If you have any questions, please contact me at (651) 604-4894 or darren.amundsen(a�stantec.com. <br /> Sincerely, <br /> Stantec <br /> -- <br /> '� �� <br /> I l <br /> � / <br /> � ___/+�_.....--. � --�CL___.._._, <br /> Darren Amundsen <br /> Cc: Chris Mattson <br />
