Provide copies of a revised survey which address the issue below. I will conduct the zoning review upon receiving a survey our engineer can approve. In the meantime I will pass the architectural plans along to the building official for the building code review.

The survey needs to show the existing storm sewer located on the SE property boundary and the edge of the stormwater pond. There is a note calling out "storm sewer on line", and I believe a dashed line indicates the storm sewer, but it is not completely clear. The existing utilities should be a different line style than the contours, easements, and setback lines. 2. The proposed retaining wall is shown at 4' in height. If when the wall is installed exceeds 4' or if a tiered wall is over 4' and not separated by 2x the height of the taller wall (as measured from the face of the upper wall to the back of the lower wall), the applicant will be required to submit plans and specifications for the wall signed by a registered professional engineer. Please contact me with any questions or concerns.

RIVER FALLS, WI 54022 15 November 2012 Dean Johnson Hometirne Video Publishing � 4355 PeaVey Road Chaska, MN 55318 Re: Footing/Foundation Plan Creekside Dear Dean: As you requested, I have reviewed the footings and foundations for the aboVe referenced project. I have also specified the garage floor precast concrete plank, and the steel beam and columns over the family room. I am providing you with"red-lined" drawings indicating the minimum structural member sizes. I am also providing you with structural notes and a stepped footing detail for this project. My office has not reviewed the remaining framing for this project. The footing/foundation design was based on framing plans provided by the truss supplier dated 11/12/12. I have assumed that shear walls are fastened to the foundation walls and that the first floor diaphragm will transfer lateral forces from the top of the concrete foundation walls. Please call me if you have any questions concerning the above. Sincerely, A.M. Structural Engineering, LLC � ; 't 1 f�� 7 � � �.;I� ,�... �,,.%/'� � f David P. Wagner, P.E. MN Reg.
