The proposed improvements include the construction of a new home and garage along with associated site grading. We have the following comments with regards to engineering matters: • If the proposed retaining walls exceed 4-feet in height or if the horizontal separation between the walls is less than two times the wall height separate engineered design and details should be submitted for review and approval. • Plans should be submitted to Hennepin County for review and approval. • The existing 964 contours shown along the north end of the property do not match the proposed spot elevations shown near the garage. The grading plan should be revised such that all existing and proposed grading is in agreement. • Erosion and sediment controls should be shown on the plans. This should include swale stabilization details. At a minimum,the swales should be staked with sod. These controls should be installed,inspected and approved by the city prior to any work on site and remain in place until all work is completed and vegetation has been established. If you have any questions please call me at(651) 604-4863.
