We have the following comments with regards to engineering matters: <br />• The house plans and elevation views show tlie garage elevation as being 956.0. However, the <br />grading plan shows an elevation of 956.5 in front of the garage. Similarly, ·the walkout elevation <br />is shown on the house plans as 946.25 whHe the grading plan shows an elevation of 946.5 along <br />the back of the house. The grading plan should be revised such that the elevations along the <br />perimeter of the house match what is shown in the other drawings. <br />• Retaining walls should be labeled as existing or proposed. <br />• Engineered design and details should be provided for all retaining walls greater than 4 feet in <br />height, or for tiered walls whose horizontal separation is less than two times the height of the <br />wall. <br />• A restoration plan or detailed notes, and an erosion control plan for any work done in the 0-75' <br />setback area must be submitted for review and approval. <br />• Final plans should include erosion and sediment control details. <br />If you have any questions, please call me at (651) 604-4863. <br />Yours very truly, <br />BONESTROO, ROSENE, ANDERLIK & ASSOCIATES, INC . <br />--(I,~ ~. <br />TomKello g <br />St. Paul, St .
