Seating with or without backs shall have a depth of not less than 18 inches, and for seating with backs, such depth shall not be greater than 20 inches. Seating with a depth of at least 36 inches, and accessible from both sides, may be credited as double seating. When seating is provided on a planter ledge, such ledge must have a minimum depth of 22 inches.
At least 75 percent of the required seating shall have a height not less than 16 inches nor greater than 20 inches above the level of the adjacent grade.
