Replatting of the tract of land is required to close and vacate the utility easements. This process was initiated by your surveyor, Schwebke-Shiskin & Associates, Inc. in 1998 (Order No. 176896) but not completed. Public Works recommends an early investigation into the platting requirements. 2. All transitions from the established street profile grade .to the building floor elevation must be accomplished on private property. Stairs, ramps, retaining walls, etc. will not be permitted in the public right of way and the record profile street grade can not be changed to accommodate the proposed building ground floor elevation. 3. Provide dimensions of the loading, parking spaces, back up distances, trash area and the stalls. Standard parking spaces are 8.5 feet wide and 18 feet long and require a 23 foot back-up distance. A Special Class II permit is required to reduce the back-up distance. 4. Verify with the Zoning Department that the column spacing/ clearance in the parking garages is sufficient. Pages LA-1. and A-200 are showing two of the main columns in the driving ramp lanes. 5. The proposed loading area needs to be redesigned. Insufficient maneuvering space is provided for the northeastern most 12'x35' loading stall to enter or exit the stall. Insufficient maneuvering space is provided. for a truck to enter the 12'x55' loading stall. 6. The maximum slope for a driveway ramp sloping downward toward the street is 1:10 for the last 20 feet to the property line.
