Honorable Chairman and Planning Commission June 4, 1999 Page Two building be looked at to see if there is a potential to step the building down in the center in an attempt to minimize some of the steep grades on the site. • Along the west edge of the project site, there is a retaining wall shown. At one point the retaining wall is nine feet high. It would be better, if possible, to terrace a retaining wall with this much height. If this is not possible, the retaining wall will need some type of fence on the top of it to protect from people falling. It is likely that a retaining wall of this size will have to be structurally designed and may require a building permit. • There is a small wetland shown in the site. The Watershed should be asked to review this wetland to determine whether it can be filled. A letter should be submitted by the Developer from the Watershed indicating their opinion on the wetland and the ability of the Developer to fill it. • No storm drainage calculations have been submitted. It is our understanding that the storm drainage calculations will show some flooding of the parking lot area on the north end of the site in an attempt to restrict the rate of runoff from the site. The City has been previously looking at the possibility of using this direction as an emergency overflow for storm drainage from Little Canada Mall located to the north. The Developer should be requested to review this situation and determine whether it would be possible to still use the storm drainage system in the service road for an emergency overflow from the Little Canada Mall in a large rainfall event. If this is possible, a storm sewer stub from catchbasin #4 to the north property line should be provided. • The storm sewer system ties into an existing culvert under the service road. This then leads to the TH 36 drainage system. The existing culvert should be inspected for condition and maintenance and, if necessary, either replaced or cleaned prior to connecting storm sewer to it. We assume that a permit from MnDOT will be necessary before connection to a culvert which flows ultimately to their drainage system. • An additional catchbasin should be provided on the east side of the easterly driveway to catch as much runoff as possible before flowing onto the street. • There is no landscaping plan provided for the site nor is there much area provided on the site for any type of landscaping. There is a small sidewalk provided around the perimeter of the building on the west side of the site. There is a retaining wall and on the remaining sides of the site there is an approximately 5 -foot green space from the parking area. C. UTILITY PLAN • There is existing sanitary sewer and watermain located in the service drive that should have sufficient capacity to provide service to the proposed development. The utility plan shows one 6 -inch water service provided to the building. The City does require that a separate line for sprinkler systems and domestic consumption be provided. Therefore, an adequately sized domestic service should also be shown on this plan with a curb stop located at the property line. O: \PR07 \8072807 \0240 \280- 0402.jun99.dg arc P " CONS PAGE 160 v
