AMENDATORY SECTION(Amending WSR 04-18-096, filed 9/1/04, effective 10/31/04)

WAC 246-260-041   Swimming pool design, construction, and equipment.   For more general design, and construction requirements that pertain to all pools, see WAC 246-260-031.

(1) Location. Owners shall ensure pump houses, planters, balconies, landscape features, trees, and structures are located fifteen feet or more horizontally away from any swimming pool, or provide barriers or other means to prevent diving or ready access to a pool from the structures. These structures do not include:

(a) Building walkways above the second story;

(b) Inaccessible roofs eight feet or more in height; or

(c) Any barriers provided to prevent unauthorized pool access (e.g., fencing).

(2) Walking deck surfaces. Owners shall design and maintain walking deck surfaces as follows:

(a) For pools less than fifteen hundred square feet, walking deck surfaces must be at least four feet wide around the entire perimeter of pools;

(b) For pools less than fifteen hundred square feet, walking deck surfaces must be at least:

(i) Six feet wide at the shallow end of a variable-depth pool; and

(ii) Six feet wide on a minimum of twenty-five percent of the deck space of free form pools.

(c) For pools fifteen hundred square feet or larger, walking deck surfaces must be at least six feet wide:

(i) Around the entire perimeter of outdoor pools;

(ii) On fifty percent of the perimeter of indoor pools; and

(iii) The remaining fifty percent perimeter of the indoor pool must be a minimum of four feet wide.

(d) For pools fifteen hundred square feet or more, walking deck surfaces must be at least sixteen square feet per bather. To determine maximum bather load see subsection (10) of this section. If the owner provides maximum facility occupancy loading less than that of subsection (10) of this section, and the occupancy limit is posted and enforced, that loading may be used in lieu of the maximum bather load figure as described under subsection (10) of this section; and

(e) General use pools may not have sand and grass areas within the pool enclosure unless these areas are separated to prevent direct access from the pool area and the facility provides a means for cleansing bather's feet before reentering the pool and deck area.

(3) Pool general floor and wall dimensional design.

(a) Owners shall ensure pool dimensional designs for floors and walls provide for safety, circulation and quality of water;

(b) Pool floors must have uniform slopes with:

(i) A maximum slope of a one-foot drop in twelve feet of run at pool depths to five or less in pools fifteen hundred square feet or more; and

(ii) Floor slopes not intruding into the area designated as the diving envelope.

(c) Pool sidewalls may not curve or intrude into the pool beyond the vertical more than twelve inches at three and one-half feet and eighteen inches at a depth of five feet. The radius of curvature of wall-floor junctions may not exceed the maximum radius designated in Table ((041.2)) 041.1 of this section for depths over five feet. Vertical means walls not greater than eleven degrees from plumb:


Table 041.1
Maximum Radius Coving or Pool Intrusion Dimensions Between Pool Floor and Wall*

POOL DEPTH 3' 3'6" 5' Greater than 5'
MINIMUM SIDEWALL DEPTH (Springline) 2'2" 2'6" 3'6" At 3'6"
MAXIMUM RADIUS OF CURVATURE 10" 12" 1'6" **Maximum radius equals pool depth minus the vertical wall depth

*Note: For pool depths falling between the depths listed, values can be interpolated.
For pool depths less than three feet and greater than five feet, values shall be extrapolated.
Radius of coving shall not intrude into pool within diving envelope.

(d) Pool configuration must have a transitional radius from wall to floor where floor slopes join walls so that:

(i) The center of the radius not less than the minimum vertical depth specified under Table ((041.2)) 041.1 of this section below the water surface level;

(ii) The arc of the radius is tangent to the wall; and

(iii) The maximum radius of coving, or any intrusion into the pool wall/floor interface, is determined by subtracting the vertical wall depth from the total pool depth.

(4) Ledges. In new construction or alterations to existing construction, ledges are prohibited in swimming pool sidewalls, except as specified in WAC 246-260-091(3).

(5) Specific design requirements for pools furnishing areas for diving. Owners shall ensure areas designated for diving activities include a diving envelope meeting minimum requirements in:

(a) D-8.01, Table 1, APHA Public Pool Regulations, 1981, if the pool user would enter from the deck level twelve inches or less from water surface level.

(b) CNCA standard configuration in areas where user would enter from the deck level over twelve inches from water level, or has a platform or diving board provided at a height of less than one-half meter (twenty inches).
