Iris ! Howard R. Green Company CONSULTING ENGINEERS Formerly MSA Consulting Engineers March 18, 1998 File: 260089m -0240 Mr. Jim March Administrator City of Centerville 1880 Main Street Centerville, MN 55038 RE: GRADING PLAN REVIEW PARKVIEW ADDITION Dear Mr. March: We received a grading plan for the proposed Parkview Addition on March 12, 1998. As requested, we have completed a review of the grading plan and offer the following comments. There are a number of required items that are missing, and it is therefore recommended that the engineer re- submit the grading plan for a final review after the noted changes have been made. GRADING PLAN • Storm sewer must be shown. The alignment must be shown, with top and invert elevations. Aprons must also be shown with invert elevations. • Centerline street elevations at 100 foot stations and street grades must be shown. • Cul -de -sac grades along the curb line with spot elevations must be shown. • House pad locations and elevations must be shown. The submitted plan indicated the pad and lowest floor elevations, but does not show the house pad location. Garage floor elevations must be a minimum of 1.5 feet above the top of curb elevation taken at the high side of the driveway. • A typical lot detail must be included on the plan indicating how lot and house elevations are shown. In previous conversations with the developer's engineer, he indicated that all homes would be split entry style construction. If this is correct, a number of lowest floor elevations must be revised to reflect this. The house style must also be noted on the grading plan. • Building setback lines must be shown. • Existing contour lines must be shown. These contours must be shown within the plat • boundaries and at least 100' into adjacent properties. 1326 Energy Park Drive • St. Paul, MN 55108 • 612/644 -4389 fax 6121644 -9446 toll free 688/3684369
