Figure 7 has two line drawing perspectives showing ramp retrofits to existing entrances originally
constructed with one or two steps. The first drawing shows a ramp along the building facade and
parallel to it with handrails on both sides and a level landing at the top at the building entrance.
Maximum ramp slope is 1:12. There are also two sets of steps down to the sidewalk from the
landing. One set is parallel to the building facade at the landing at the high end of the ramp and
the other at 90 degrees to the ramp and perpendicular to the facade. Both connect to the
sidewalk and are protected by planters at the corners where the steps project into the sidewalk. A
sidewalk width of approximately 12 feet is required for this approach. This includes a minimum
5x5-foot landing (6 feet is desirable) at the entrance, where the steps were originally located.
A similar drawing shows the addition of an entrance ramp in a narrower sidewalk. Where only 8 feet of sidewalk width is available, the parallel ramp and its landing may extend only 4 feet into the sidewalk from the building. A single set of steps runs parallel to the facade at the landing at the high end of the ramp; there is not enough sidewalk with for perpendicular steps. Part of the landing space needed to approach and open the entrance doors is recessed into the building.
