Howard R, Green Company July 2, 2004 File: 803950)-0325 Honorable Chair and Planning Commission City of Little Canada 515 Little Canada Road E Little Canada, MN 55117-1633 RE: GERVAIS HILLS DEVELOPMENT CITY OF LITTLE CANADA Dear Planning Commission Members: As requested we have reviewed the submittal package for the proposed Gervais Hills Development located south of County Road B2. The submittal package included a site plan, grading plan, and utility plan completed by Stevens Engineers and dated 6/15/04. Based upon our review we would offer the following comments: Grading Plan 1. All drainage from individual lots must be conveyed within the public drainage and utility easements around each lot. Drainage swales should be added or improved between lots 2 and 3, 3 and 4, 5 and 6, 8 and 9, and 9 and 10 or the drainage and utility easements increased. It also appears that the drainage and utility easement along the back sides of lots 1 thru 4 should be expanded to ensure that drainage from adjacent lots is kept within the easements. 2. The plan indicates that an existing sanitary sewer manhole is located just north of lot 12. As shown this manhole will be within pond "AP 5". The sanitary manhole top will need to be adjusted to grade. In addition information should be provided as to the peak elevation of the pond to ensure that the sanitary manhole will not be under water. 3. The existing driveway access to County Road 62 on the proposed lot 12 should be removed. The existing driveway access to County Road B2 should also be eliminated, the storm sewer culverts removed, and the ditch graded through the existing driveways to maintain current drainage patterns. 4. Note number 1 under the "Ponding Construction Notes" indicates that structural soils from park areas may be used. There does not appear to be any park area designated in the development. It appears that the note may refer to the ponding areas instead of the park areas.
