oward R, Green CoTpa October 18, 2002 File: 819110) -0240 Honorable Mayor and City Council City of Little Canada 515 Little Canada Road East Little Canada, MN 55117 -1633 RE: DRYWALL SUPPLY ADDITION Dear Mayor and Council Members: 'ly As requested, we have reviewed the submittal package for the proposed Drywall Supply Addition site located off of Country Drive, The submittal documents were prepared by Anderson Engineering of Minnesota, LLC, and included a preliminary plat, an alternate site plan preliminary plat, grading plan, utility plan, and landscape plan. Drainage calculations were also submitted. Based upon our review, we would offer the following comments: 1. A 10 -foot drainage and utility easement should be shown along Country Drive to ensure the existing watermain will be within the easement. 2. The proposed grading around the future building should be shown. 3. The function of the stormwater pond shown on the plans to provide for storm water discharge rate control from the site. We would suggest that the pond be constructed with dead storage area to provide for some sediment removal prior to discharge from the site. This could be accomplished with minimal or no increase in the area needed for the pond. A outlet structure or weir should be utilized to control the discharge rate during small rain events. 4. More detail will need to be given on the storm sewer system running through the sites. It may be necessary to add additional catchbasins to pick up stormwater runoff from the proposed access streets and future building sites. It will also need to be shown that the storm sewer being installed will be at sufficient depth to serve the two lots along Country Drive. 5. All but approximately 350 feet of the existing 6 -inch watermain is shown as being replaced. We would suggest that the entire watermain loop through the property be reconstructed using 8 -inch watermain. 6. The current width of the main entrance is shown as 42 feet. This would be sufficient if trucks are only allowed to make movements thru the site as illustrated on the drawings. If any truck traffic will be entering using the main entrance the inbound lane should be widened to 16 feet, for a total width of 44 feet. The comments listed above are being provided to assist the City Council in the review of the concept layout for the Drywall Supply site. When the concept layout is approved by the City Council, a more detailed review of the submittal documents will be completed and comments sent to the developer for implementation into the plan.
