   R403.1.7.3.2 Determination and approval of elevations.
   1.   The owner of property to be developed in the R-l and R-2 zoning districts in the city shall provide a topographic survey depicting the undeveloped topography, at a minimum one-foot (1') contour, which shall be prepared, signed and certified by a Registered Illinois Land Surveyor or a Registered Illinois Professional Engineer and tied to a benchmark recognized by the city.

      e.   Side-yard swales shall direct surface runoff away from all adjacent buildings and shall have a minimum slope of one and one-half percent (1-1/2%) to the drainage outlet for the lot.
      f.   Landscape walls or retaining walls, as defined in § 156.004 of the city’s code, shall be allowed as a means to comply with the site grading requirements provided for herein.
   4.   The FFE of the first above-ground level of a building shall be no more than two feet (2') above the TOF elevation for the building; provided that when the FFE is more than one and one-half feet (1-1/2') above the TOF elevation, the differential shall be masked on the exterior of the building through the use of dropped siding, a brick ledge or other building construction technique approved by the Director of Community and Economic Development and city engineer.
   5.   The elevation of the ground surface along the perimeter of the building shall be set at least four inches (4") below the TOF elevation, and shall slope away at a minimum slope of one and one-half percent (1-1/2%) or 66.7:1), and a maximum slope of twenty-five percent (25%) or 4:1 to the lot lines.
