~L~~RING ~ ~SSU(I~T~S ruua uouru May 29, 2009 File: 120121 E-0240 Honorable Chair and Planning Commission City of Little Canada 515 Little Canada Road East Little Canada, MN 55117-1633 RE: HUOT ADDITION CITY OF LITTLE CANADA Dear Planning Commission: We have reviewed the most recently submitted package for the proposed Huot Addition (previously Denny Claridge development) located in the northwest corner of the Edgerton Street and Little Canada Road intersection. The submittal documents included a preliminary plat, grading plan, utility plan, and drainage calculations all dated May 13, 2009. Based upon our review we would offer the following comments. Grading Plan 1. The plan was not scalable at 1"=30' and therefore exact grades could not be determined. Any future submittals should be scalable. It appears that some slopes are in excess of the maximum allowed grade of 3:1 that was recommended. 2. Multiple retaining walls are shown on the plan. The wall proposed for Lot 1 should have top and bottom of wall elevations noted. In addition, several of the walls are proposed to exceed 4-feet in height. Retaining wall plans signed by a licensed engineer will be required prior to final approval. 3. The ponding area on the north end of the development is proposed to pipe discharge to the north. Rip rap should be added at the outlet to protect against erosion. 4. Based on the disturbed area the Ramsey Washington Metro Watershed requirements and permit along with a NPDES permit apply. 5. A swale will be required along the back of the house proposed at Lot 5 to direct water away from the foundation. 6. We would recommend moving the culvert proposed under the driveway for Lot 5 closer to Edgerton Street so that the culvert is not under the proposed retaining wall.
