Generated explanation

The illustration shows a side-view cross section of an exterior stairwell descending to a basement door, with a perspective inset locating the stairwell beside a house. Railings protect the stairwell opening, and a sloping handrail follows the stairs. Annotations call for a 4- to 6-inch door threshold, a drain at the bottom landing, and soil sloping away from the stairwell to reduce water pressure on its side walls. The side wall is identified for inspection for bowing or cracks. The foundation section indicates the old footing location and a lowered footing extending below and to either side of the stairwell.
