We have the <br /> following comments with regards to engineering matters: <br /> • Engineered design and details should be submitted for review and approval for all retaining walls over 4' <br /> in height, and for all tiered walls with a separation of less than 2 times the wall height. <br /> • It appears that 2 proposed 962 contour lines converge near the northwest corner of the house. The <br /> grading plan should be revised such that no contour lines converge. This may require extending the <br /> proposed retaining wall to the northeast. <br /> • The final plan should show more detail as to how the area along the road, specifically near the driveway, <br /> will drain. <br /> • The sewer and water services shouid be shown on the plan. <br /> • The final plan should indicate which trees will be removed. <br /> • Final plans should include erosion and sediment control details. <br /> If you have any questions, please call me at(651) 604-4894. <br /> Yours very truly, <br /> BONESTROO, ROSENE, ANDERLIK& ASSOCIATES, INC. <br /> � i , <br /> Darren Amundsen <br /> Cc: Tom Kellogg <br /> Bonestroo recently merged w'�th DSU,bringing together some of the best regional talents in engineering,architecture,planning,landscape architecture, <br /> and urban design.
