Section 3701 DEFINITIONS. For the purpose of this Article certain terms
are hereby defined as follows:
"Pool" shall mean any body of water created by artificial means
which is designed or used for swimming or immersion purposes by men,
women, or children and which has a water depth exceeding 18 inches.
The term "pool" shall include swimming pools, spas, hot tubs and above
and below ground vinyl -lined pools but does not apply to plumbing fixtures
such as bathtubs; nor does it apply to man -made lakes, reservoirs, or farm
ponds used primarily for public park purposes, water conservation,
irrigation, or watering of livestock.
Section 3702 POOL DESIGN AND CONSTRUCTION.
3702.1 GENERAL. Pool design and construction shall be in accordance
with accepted engineering practice, shall be in conformity with applicable
Ordinance No. 365
Page 22
provisions of the adopted building, electrical, plumbing, and mechanical codes,
and shall be structurally suitable for the soil, topographic, and geologic conditions
prevailing at the construction site.
3702.2 EXPANSIVE SOIL DESIGN. Pools constructed at grade shall be
designed on the assumption that their construction is to be in an area of
moderately expansive soil having an expansion index of 51 -90 and an equivalent
fluid pressure of not less than 45 pounds per cubic foot (45 p.c.f.). Exception:
Where tests indicate that soils at a pool site are non - expansive or have low
expansion characteristics from the ground surface to the full depth of the pool,
structural design may be based on an equivalent fluid pressures not less than 30
p.c.f.
In highly expansive soils having an expansion index of 91 -130, pools shall
be designed for not less than 60 p.c.f. equivalent fluid pressure. In very highly
expansive soils having an expansion index over 130, pool design shall be subject
to special requirements based on a site investigation, soil testing, and
engineering analysis by a registered civil engineer to determine appropriate
design parameters for the site.
3702.3 HYDROSTATIC UPLIFT. In areas of anticipated high water table,
an approved hydrostatic relief system or device shall be installed.
3702.4 THERMAL PROTECTION FOR PLASTIC PIPING. Between the
inlet of pool water heating equipment and any plastic water piping connected
thereto, a check valve shall be installed to prevent thermal damage to such
piping due to backflow. Exception: When rapid or high -rate filters are employed,
a check valve may be omitted.
Between the outlet of pool heating equipment and any plastic water piping
connected thereto, not less than 5 feet of approved metal pipe shall be installed
for the purpose of dissipating heat.
3702.5 SAFEGUARDING SUCTION DRAINS. Bottom drains and suction
intakes in pools and spas shall be covered with grated or other protective devices
which cannot be removed except with tools. The slots or openings in these
covers shall be of such area, shape, and arrangement as to prevent bathers from
being drawn thereto with such force as to constitute a safety hazard.
3702.6 GRAB BARS. Wherever egress from a pool by bathers is
restricted by the presence of a vertical wall or other barrier which extends more
than 12 inches above the water at the pool's edge, permanent handrail, grab
bars, or equivalent device(s) shall be installed within 12 inches of the water
surface, capable of being securely grasped and adequate to support the weight
of a user of the pool.
Ordinance No. 365
Page 23
Section 3703 DECKS
3703.1 GENERAL. A deck shall be provided around below -grade
swimming pools except when special engineering design is furnished which
indicates that such deck is not necessary for the purpose of maintaining the
structural integrity of the pool and /or for controlling surface water and moisture
content in the soil adjacent to the pool. Decks shall not be required for spas and
hot tubs.
3703.2 DECK DESIGN AND CONSTRUCTION. Required decks shall be
constructed of concrete or other approved impervious material and shall be
sloped to provide positive drainage away from the perimeter of the pool. Except
as provided below, decks shall have a minimum width of four feet and shall be at
least 3 1/2 inches in thickness. Reinforcement shall be #3 bars spaced not over
24 inches on center each way, or equivalent reinforcing,
Approved joints shall be provided in the deck at corners, at maximum 10
foot intervals, and wherever necessary in order to control cracking, to allow for
differential movement and to minimize damage to the deck from such movement
should it occur. Joints in decks and coping shall be made watertight with an
approved permanent resilient sealant.
3703.3 CUTOFF WALLS. At the outer perimeter of pool decks a cutoff
wall of approved material shall be installed below -grade to a depth of at least 15
inches so as to form a permanent and effective vertical moisture barrier.
Exceptions:
A cutoff wall may be omitted when a deck at least 6 feet wide is
installed.
2. Decks less than four feet in width may be installed provided that the
required cutoff wall is increased in depth beyond the minimum by an amount
directly proportional to the reduction in deck width.
3703.4 PRE - SATURATION, HIGHLY EXPANSIVE SOILS. When the soil
below a deck has an expansion index of 91 or greater, it shall be saturated with
water to a depth of at least 18 inches prior to installation of the deck.
Section 3704. DRAINAGE AND DISPOSAL
3704.1 SURFACE WATER. Surface water from pool decks shall be
collected and conducted through non - erosive devices to a street, storm drain, or
other approved watercourse or disposal area.

disposal except when specifically approved for the purpose and when it has been
determined that such installation is not likely to have adverse effects on the
structural stability of the pool or other structures on the site. The Building Official
may require a percolation test, soils report, and /or geological report to make such
a determination.
Section 3705. SPECIAL INSPECTION. Special inspection shall be
provided for pneumatically placed concrete (gunite) in swimming pools.
Section 3706. FENCING AND GATES. Any person, firm, or corporation
in possession of land either as owner in fee, purchaser under contract, lessee,
tenant, licensee or any type of legal estate upon which is situated a pool as
defined above shall at all times maintain on the lot or premises a fence or wall
not less than five feet in height which completely surrounds such pool or body of
water provided, however, that a dwelling or accessory building may be used as a
part of such enclosure. Said fence shall be constructed of durable material and
shall be designed to withstand a horizontal force of at least 20 pounds per lineal
foot at the top of the fence or top of the railing. Openings, holes, or gaps therein
shall be no larger than 4 inches wide except for openings closed by doors or
gates. Fences shall not have a configuration which provides a ladder -like access
to the pool area.
Each gate or door opening through a pool enclosure shall be equipped
with a self - closing and self - latching device capable of keeping the gate or door
securely closed at all times when not in use.
