Footnotes to Table 1809.7
1. Pre - moistening is required where specified in Table CBC 1809.7 in order to
achieve maximum and uniform expansion of the soil prior to construction and
thus limit structural distress caused by uneven expansion and shrinkage.
Other systems, which do not include pre- moistening, may be approved by
the Building Official, when such alternatives are shown to provide equivalent
safeguards against the adverse effects of expansive soil.
2. Under -floor access crawl holes shall be provided with curbs extending not
less than 6 inches above adjacent grade to prevent surface water from
entering the foundation area.
3. Reinforcement for continuous foundations shall be placed not less than 3
inches above the bottom of the footing and not less than 3 inches below the
top of the stem.
4. Slab reinforcement shall be placed at mid -depth and continue to within two
inches of the exterior face of the exterior face of the exterior footing walls.
5. Moisture content of soils shall be maintained until foundations and piers are
poured and a vapor barrier is installed. Test shall be taken within 24 hours of
each slab pour.
6. Crawl spaces under raised floors need not be pre- moistened except under
interior footings. Interior footings which are not enclosed by a continuous
perimeter foundation system or equivalent concrete or masonry moisture
barrier shall be designed and constructed as specified for perimeter footings
in Table CBC 1809.7.
7. A grade beam not less than 12 inches X 12 inches in cross - sectional area,
reinforced as specified for continuous foundations in Table CBC 1809.7,
shall be provided at garage door openings.

structurally suitable for the soil, topographic, and geologic conditions prevailing at
the construction site.
3109.6.2 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.
3109.6.3 Hydrostatic Uplift. In areas of anticipated high water table, an approved
hydrostatic relief system or device shall be installed.
3109.6.4 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.

Ordinance No. 399
Page 12
3109.6.6 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.
3109.6.7 Decks
3109.6.7.1 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.
3109.6.7.2 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.
3109.6.7.3 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:
1. A cutoff wall may be omitted when a deck at least six 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.
3109.6.7.4 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.
3109.6.7.5 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.

FOOTNOTES TO TABLE CRC R403.1
1. Pre - moistening is required where specified in Table CRC R403.1 in order to
achieve maximum and uniform expansion of the soil prior to construction and
thus limit structural distress caused by uneven expansion and shrinkage.
Other systems, which do not include pre- moistening, may be approved by
the Building Official, when such alternatives are shown to provide equivalent
safeguards against the adverse effects of expansive soil.
2. Under -floor access crawl holes shall be provided with curbs extending not
less than 6 inches above adjacent grade to prevent surface water from
entering the foundation area.
3. Reinforcement for continuous foundations shall be placed not less than 3
inches above the bottom of the footing and not less than 3 inches below the
top of the stem.
4. Slab reinforcement shall be placed at mid -depth and continue to within 2
inches of the exterior face of the exterior face of the exterior footing walls.
5. Moisture content of soils shall be maintained until foundations and piers are
poured and a vapor barrier is installed. Test shall be taken within 24 hours of
each slab pour.
6. Crawl spaces under raised floors need not be pre- moistened except under
interior footings. Interior footings which are not enclosed by a continuous
perimeter foundation system or equivalent concrete or masonry moisture
barrier shall be designed and constructed as specified for perimeter footings
in Table CRC R403.1.
7. A grade beam not less than 12 inches X 12 inches in cross - sectional area,
reinforced as specified for continuous foundations in Table CRC R403.1,
shall be provided at garage door openings.
8. Foundation stem walls which exceed a height of three times the stem
thickness above lowest adjacent grade shall be reinforced in accordance
with Sections 18 and 19 in the California Building Code, or as required by
engineering design, whichever is more restrictive.
9. Footing widths may be reduced upon submittal of calculations by a
registered civil or structural engineer or licensed architect, but shall be a
minimum of 12 inches for one and two -story structures and 15 inches for
three -story structures.
10. Bent reinforcing bar between exterior footing and slab shall be omitted when
floor is designed as an independent, "floating" slab.
11. Fireplace footings shall be reinforced with a horizontal grid located 3 inches
above the bottom of the footing and consisting of not less than No. 4 bars at
12 inches on center each way. Vertical chimney reinforcing bars shall be
hooked under the grid.
12. Underground utility conduits shall be installed prior to foundation inspection
and shall extend beyond the foundation.
