SEH Architects 113 5th Avenue South St. Cloud, MN 56301 RE: Revised Utility Plan & Grading & Drainage Plan Cottages of Albertville BWK Job #96296 Dear Mr. Carlson: Endosed for your review, please find one revised Utility Plan and one revised Grading & Drainage Plan for the Cottages of Albertville development. The northerly stonn pipe system will outlet into the existing 15" RCP line from the west as discussed during our March 31 telephone conversation. I have talked with Mr. Scott Dahlke at Meyer-Rohlin, Inc., and he has verified that this line was intended to carry storm water from the outlot. The southerly storm pipe system is proposed to outlet westerly and will be picked up in the Center Oaks design. These systems were sized according to the 10 year, 24 hour storm frequency. The site is graded so that flows from heavier stonns will drain easterly and exit into the County Highway 19 ditch. I will be submitting the same plans to Mr. Virgil Hawkins, Assistant Wright County Engineer for comment. Please review and comment. I look forward to working with you and! the City of Albertville as this project progresses. If you have any questions, please call. Thank you.
