Current through Register Vol. 30, No. 28, July 12, 2024
A.
				Decks, ramps, coping, and similar step surfaces shall be constructed of
				concrete or other inorganic material, have a slip-resistant finish, and be
				easily cleanable.
B. The minimum
				continuous unobstructed deck width, including the coping, shall be 10 feet for
				a public swimming pool and 4 feet for a semipublic swimming pool. The
				dimensional design of decks at public and semipublic swimming pools shall
				comply with the dimensions shown in Illustration B.
C. A minimum 5 feet of deck width shall be
				provided on the sides and rear of any diving equipment at a public swimming
				pool. A minimum 4 feet of deck width shall be provided on the sides and rear of
				any diving equipment at a semipublic swimming pool. If diving equipment is
				installed at a public swimming pool, there shall be a minimum 15 feet of deck
				width from the swimming pool wall to the edge of the deck behind the diving
				equipment [See Illustration B].
D.
				A continuous unobstructed deck width of at least 4 feet, which may include the
				coping, shall be provided on at least two contiguous sides and around at least
				50% of the perimeter of a public or semipublic spa.
E. Decks shall be sloped to effectively drain
				either to perimeter areas or to deck drains. Drainage shall remove splash
				water, deck cleaning water, and rain water without leaving standing water. The
				minimum slope of the deck shall be 1/4 inch per 1 foot. The maximum slope of
				the deck shall be 1 inch per 1 foot, except for ramps.
F. Decks shall be edged to eliminate sharp
				corners.
G. Site drainage shall be
				provided to direct all perimeter deck drainage and general site and roof
				drainage away from a public or semipublic swimming pool or spa. Yard drains may
				be required to prevent the accumulation or puddling of water in the general
				area of the deck and related improvements.
H. Hose bibbs shall be provided along the
				perimeter of the deck so that all parts of the deck may be washed down. At a
				minimum, each hose bibb shall be protected against back siphonage with an
				atmospheric vacuum breaker. The Department may approve quick disconnect style
				hose bibbs.
I. Any valve that is
				installed in or under any deck shall provide a minimum 10-inch diameter access
				cover and a valve pit to facilitate the repair and maintenance of the
				valve.
J. Joints in decks shall be
				provided to minimize the potential for cracks due to changes in elevations or
				movement of the slab. The maximum voids between adjoining concrete slabs or
				between concrete slabs and expansion joint material shall be 3/16 inch of
				horizontal clearance with a maximum difference in vertical elevation of 1/4
				inch. Areas where the deck joins concrete shall be protected by expansion
				joints to protect the swimming pool or spa from the pressures of relative
				movements. Construction joints where pool or spa coping meets the deck shall be
				watertight and shall not allow water to pass through to the underlying
				ground.
