8. Staging of seeding in compliance with MnDot specifications as to time lines for planting as well as with NPDES and RWMWD requirements pursuant to 1005.020 (d)(10). 9. A demolition permit for 459 Viking Drive due to the alignment of Preserve Trail. Said permit shall require appropriate utility disconnects as approved by Little Canada's Public Works Department to prevent leakage from water lines and/or seepage into the sanitary sewer system. City Engineer: As requested we have reviewed the final plat submittal package for the proposed "The Preserve" development located east of McMenemy Street and north of Viking Drive. Metro Land Surveying prepared the submittal package and the plans are signed 9/15/05. Also included were storm water calculations. Based upon our review we would offer the following comments. Plat 1. An access limitation should be shown on the west lot line of Lot 1 to prevent driveway access to McMenemy Street. Grading Plan 1. A ten -foot bench graded for vehicle access should be provided around the top of all the ponds for future city maintenance. The access roads to the ponds should be designated on the plan and must be within the drainage and utility easements granted. 2. The plan indicates an ordinary high water level of the wetland to the north. The source of this information should be provided and proof of its accuracy. 3. Boulevard grades appear to be as steep as 3:1 in some areas. The Developer previously agreed to grade a 5 -foot boulevard behind the curb at 2% and a maximum of 3:1 slopes after the boulevard. 4. Several notes are included on the grading plan as to a maximum wall height of 4 feet. It appears that the wall on Lot 3 is six feet high. All walls should be reviewed for a maximum height of 4 feet and top and bottom wall elevations provided on all walls to ensure this. 5. The drainage swale that is shown between Lot 3 and Lot 4 is not contained within the drainage and utility easement that is being dedicated and is very close to the proposed house pad location. The drainage ditch should be widened and constructed per the detail provided in the plans. It may be necessary to grant a larger drainage and utility easement so that the swale is entirely within the easement. It should also be noted that the drainage swales will need to be graded back to the edge of the no disturb zone to ensure that the storm water runoff from each lot does not drain onto adjacent property behind the houses in the area that can be graded and developed. 6. Top of curb elevations should be provided at all radius points. In addition, the existing centerline and edge of bituminous elevations should be shown for McMenemy Street and Viking Drive to ensure smooth connections can be made. 7. As shown there is a retaining wall extending up the east side of the building pad of Lot 11 directly adjacent to the property line. The City requires that a minimum of a 6 -foot
