Honorable Chairman and Planning Commission January 5, 2001 Page Two Building 1 is labeled as a walkout (WO) with a bottom floor elevation of 950.10. The grading plan shows a proposed 954 contour tying into the northeast corner of the building along with an existing 952. It appears that the easterly most unit in building 1 could not be a walkout and should not be labeled as such. 6. There must be handicap access to the buildings at a grade no greater than 20:1 (H:V). It appears grades from the parking lot near the handicap stalls are in excess of 10:1. However no pedestrian ramp locations are noted on the plans to verify exact grades. No elevations are shown for the retaining wall top and bottom however; based on the proposed contours the retaining wall will be a maximum of 4 -feet tall and would be acceptable. Elevations should be added to the retaining wall and any wall over 5 -feet tall should be terraced. 8. Although pipe grades can be determined from the invert elevations shown on the plans and pipe lengths can be scaled, no pipe diameters are shown. There may be a conflict between the storm sewer outlet pipe and the proposed retaining wall dependent on pipe size, required bury depth of the wall, and the elevation of the flared end section. 9. The section shown for the parking lot is only 6- inches of aggregate base and 2- inches of bituminous. We question if this would be adequate especially for garbage trucks and other heavy vehicle that may need to use the parking lot. B. UTILITY IMPROVEMENTS 1. There appears to be only about 5 to 7 feet between the hydrant and :he retaining wall. Insulation may need to be added to insure against freezing. 2. The proposed watermain is 6" DIP and only 1 -1/4 inch water services are being shown. The 6" main would be adequate for service use only; building fire protection would require the installation of a larger main, If you have any questions regarding these comments. please call.
