Howarc R. Green Company CONSULTING ENGINEERS October 23, 1998 File: 803660J-0240 Ms. Kathy Glanzer Deputy City Clerk City of Little Canada 515 Little Canada Road Little Canada, MN 55117 RE: GILANDERI ADDITION Dear Ms. Glanzer: it St. CO \SCLTISCElOI%EERS Formerly MSA Consulting Engineers As requested, we have reviewed the revised submittal for the Gilander Addition. This submittal consisted of a revised preliminary plat, dated October 19, 1998 and prepared by E.G. Rud and Sons, Inc., and also revised storm sewer calculations, dated May 29, 1998, prepared by Charles W. Plowe, Consulting Engineer. Based on our review, we would offer the following comments. 1. The proposed plat still contains five lots. The most northerly lot shows its access off County Road B2, with the remaining four lots with access off Gilander Lane. 2. The revised plat shows a dedication of 37.5 feet of right -of -way, and a proposed road construction, which is 24 feet wide with concrete curb and gutter. City ordinance would require that the minimum road width for this area be 28 feet, face to face, however, none of the roads in this area of town are over 24 feet wide, and some are even narrower. In a December 8, 1997 memo to the Planning Commission, the City Planner recommended a 24 -foot wide road. This would match the width of the roadway leading from County Road B2 into this area. I would concur with that recommendation, but suggest that the 24 -foot width be measured from face of curb to face of curb. 3. The grading plan shows all five houses to be of a walkout style. This requires significant filling of the property. Therefore, most if not all of the trees on the site will be removed from the road through the front yards and building pads on each lot. The grading plan shows that the driveways along Gilanderi Lane have low points located halfway between the garage and the curb. Water drains both directions to these low points, and then drains around the house to the rear of the lots. This type of design does not work very well in Minnesota in the winter months. When the mid - winter or spring melt occurs, there will likely be large piles of snow on either side of the driveway, causing driveway flooding. We would suggest that the house pads be raised slightly, to get the driveways to drain from the garage to the street. If there is a concern about removing more trees by raising the house pads, this could be minimized by a small retaining wall in the rear yards.
