Melanie Cuitii Planner CityofOrono Peat OflBoe Box 66 Ciyilal Bay. MN SS323 1220 Tonkawa Pile No. I39-04-I Plat No. 04-3060 Dear Mehnie; We have reviewed the iketdi plan for the proposed grading and shoreline improvements 10 the property located at 1220 Tonkawa. The propo^ improvements include the construction ofretaining walls and associated site improvements along tfie lito side of die home. We have the following comments with regards to engineering matters: • The proposed sketch does not provide sufficient detail for us to comment on. A detailed plan should be submitted that includes existing and proposed contours extending SO-feet beyond all lot lines. The plans should accurately show topography including all lot lines, existinr '*s, buildings, retaining walls and any other structures and hardcover. • The plans should include at least three sections showing existing and propo levations between die lake and the home across the frontage of the property. s Additumal retaining wall information should be provided with the revised plans. At a minimum the proposed wall type should be identified as well as die proposed top and bottom of wall elevations. The plam should clearly identify existing and proposed walls. Any walls that exceed 4-feet in height require a separate engineered design and d^l subnuttal. • The plans should iiKlude erosion and sediment control details and detailed planting and restoration information. If you have any questions please call me at (6S1) 604-4863. Yours very tiul^,I BONESTROO, ROSENE. ANDERLK A ASSOCIATES. INC. Tom Kellogg Ce: GregOappa,CityofOrono • St. Paul. St. Cloud, Rochester.
