The plans are dated 7-20-10. We have the following comments with regards to engineering matters: • It appears that the proposed retaining wall in the back of the house is approximately 5 feet high in areas. Engineered design and details should be submitted for review and approval for all retaining walls over four in height, and for all tiered walls with a separation of less than two times the wall height. • The plans should show a proposed driveway culvert at Spring Hill Road to maintain the existing ditch drainage. • The plans should note any driveway removal and restoration work located within the existing easement at 445 Spring Hill Road. • The plans must show existing contours at least 50 feet on to the surrounding properties. • This project will disturb more than one acre and require a MPCA NPDES permit. • This project will disturb more than 100 CY of material. Sediment and erosion control information meeting the requirements of Orono's City Code 79-7(c)(2) must be submitted. A $4000 sediment and erosion control financial security should be required of the owner for this permit. If you have any questions, please call me at (651) 604-4894 or send an email to darren.amundsen@bonestroo.com. Yours very truly, �� i .

Kyle had a meeting last Thursday to discuss this with the project team and owner. I haven't heard if anything was decided, but this letter would let them know that the current plan is acceptable if they were to move forward with that.
