Reference: Molin Concrete <br /> Copies To: James E. Studenski, P.E. Drainage Review <br /> City of Lino Lakes, Minnesota <br /> From: Connie J. Taillon,P.E. Proj. No.: 13810.006 <br /> Date: March 30, 2007 Routing: <br /> The following review is based on these submittals: <br /> 1. Molin Concrete Addition Preliminary Grading and Utility Plan(Office and Overall) and SWPPP, <br /> submitted by Plowe Engineering, dated November 21, 2006, and revised March 22, 2007. <br /> 2. Moline Concrete Addition Drainage Calculations, submitted by Plowe Engineering, dated <br /> November 16, 2006, and revised January 11, 2007. <br /> • The following are significant issues that must be addressed prior to preliminary plat approval: <br /> l: Provide information regarding the type of soil and ground water elevation at the location of the <br /> Infiltration Basin. There should be a minimum of 3 feet of separation between the ground water <br /> elevation and the bottom of the Infiltration Basin. <br /> The following are minor plan, calculations, and drafting corrections that must be addressed prior to final <br /> approval.- <br /> 1. The Grading Plan shows that the proposed culvert located north of the proposed office building is <br /> discharging towards the existing office building and ascending slope. Direct the culvert away from <br /> the existing building. <br /> 2. Determine the high water level at the upstream end of the culvert located north of the proposed <br /> office building. Label the high water level of the culvert on the Grading and Utility Plan. <br /> 3. Show the location and elevation of the emergency overflow for the proposed culvert located north <br /> of the proposed office building on the Grading and Utility Plan. The low opening elevations of <br /> adjacent buildings are required to be 1 foot above the emergency overflow elevation. <br /> 4. It appears that runoff from the parking area located south of the proposed office building flows <br /> south to Lilac Street,not to proposed Pond 9, as shown on the watershed maps. Ensure that runoff <br /> from the roof of the proposed office building is directed to Pond 9,not to the south parking area. <br /> • 5. Include a rock construction entrance detail on the Plan. <br /> 6. Show the location of the rock construction entrance and silt fence on the Grading and Utility Plan. <br /> An Employee Owned Company Promoting Affirmative Action and Equal Opportunity <br />
