Howard R. Green Company CONSULTING ENGINEERS January 6, 2000 File: 809320)-0240 Honorable Chairman and Planning Commission City of Little Canada 515 Little Canada Road Little Canada, MN 55117 RE: RICE STREET CAR WASH Dear Planning Commission Members: As requested, we have reviewed the submittal package for the Rice Street Car Wash site development proposal. The submittal package consisted of a seven-page plan set including title sheet, existing ccnditions, site plan, grading plan, utility plan, preliminary plat and detail sheet. The submittal package was prepared by Loucks and Associates. Also submitted were exterior elevations and floor plans. Based upon your review and discussions with Greg Schroeder, Public Works Director we would offer the following comments: A. Preliminary Site Plan :• The parking layout shows 22-foot wide drive lanes with 20-foot deep parking stalls. We would suggest around the perimeter of the site where the parked vehicle has an opportunity to overhang the curb that the dimensions be changed to be 18-foot deep parking stalls and 24-foot wide isles. The 24-foot width provides slightly more room far maneuvering vehicles. :• Only two handicapped stalls are shown near the front of the building. We question whether two are adequate for the total development and whether or not they should be spread out along the front of the proposed retail space. Also a handicapped ramp will need to be provided somewhere along the front sidewalk of the proposed building. •3 Up near the northeast end of the proposed building the corner-parking stall should be provided with a bump out in the curb line to facilitate backing movements out of that stall. B. Grading, Drainage and Erosion Control Plan :• No drainage calculations were submitted. These will need to be submitted, reviewed and approved prior to final approval of the development. The proposed pond at the rear of the development shows a high water level of 950. The top of the berm surrounding the pond is just slightly above 950. We would suggest that at least one-foot of free board be provided from the high water level to the top of the berm. Also an emergency overflow should be provided somewhere near the pond outlet in case the pipe is plugged. This will eliminate potential flooding of the area to the east of the pond. Was the pond sized to ultimately service outlot A, if not should it be? O:\PROJ\809320)\0240\Itr 1-6-00 planning commis Page 46 1326 Energy Park Drive . St. Paul, MN ./644-9446 toll free 888/368-4389
