5.5.1
Offset ledges shall be a maximum of 8
inches (20.3 cm) wide.
5.5.1.1
Offset ledges, located less than
42 inches (1067 mm) below waterline shall be pro-
portionately less than 8 inches (20.3 cm) wide and
fall within 11
°
from plumb, measured from the top of
the waterline. See figure 4.
5.6
Floor slopes.
Floor slopes shall be
reasonably uniform and comply with 5.6.1 through
5.6.3.
5.6.1
The slope of the floor from the shallow end
wall towards the deep area shall not exceed 1 foot in
7 feet (30 cm: 213 cm) to the point of the first slope
change as shown in figure 5.
5.6.2
Changes in slope between shallow and deep
areas shall be at a minimum water depth of 2 feet 9
inches (83.8 cm) and be at least six feet (182.9 cm)
from the shallow end, except as specified in 6.3.
5.6.3
The slope of the floor from the point of the
first slope change toward the deep end shall not
exceed 1 foot in 3 feet (30 cm: 91 cm).
