We have the following comments with regards to engineering <br /> matters: <br /> • The proposed retaining wall along the east side of the home is shown as 4.0 feet in <br /> height. If field changes increase the height, engineering design and details must be <br /> submitted for review. <br /> • The grading plan should be clarified so that a high point is shown in the proposed <br /> driveway at or near elevation 955. This existing high point is likely located near the word <br /> "GRAVEL" on the "EXISTING GRAVEL DRIVEWAY" label shown on the plan. The goal of <br /> this would be to maintain existing drainage patterns and not increase the amount of <br /> runoff to the adjacent west property. Generally, the roadside of the house would <br /> ultimately drain around the east side of the house to the lake entirely within the <br /> property. <br /> • This project will disturb more than 100 CY of material. Sediment and erosion control <br /> information meeting the requirements of Orono's City Code 79-7(c)(2) must be <br /> submitted. The minimum $2000 sediment and erosion control financial security should <br /> be required of the owner for this permit. <br /> If you have any questions, please call me at(651) 604-4894 or send an email to <br /> darren.amundsenCa�bonestroo.com. <br /> Sincerely, <br /> BONESTROO <br /> �-____;-- �i.���---, <br /> Darren Amundsen <br /> Cc: Tom Kellogg <br /> Chris Mattson <br />
