FOOTNOTES TO TABLE UBC 18 -I -C
1. Premoistening is required where specified in Table UBC 18 -I-
C 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. Underfloor access crawl holes shall be provided with curbs
extending not less than six (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" above the bottom of the footing and not less
than 3" 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 premoistened
except under interior footings. Interior footings which are
not enclosed by a continuous perimeter foundation system or
equivalent concrete or masonry moisture barrier complying
with Section UBC 1806.3 in this ordinance shall be designed
and constructed as specified for perimeter footings in Table
UBC 18 -I -C.
7. A grade beam not less than 12" X 12" in cross - sectional
area, reinforced as specified for continuous foundations in
Table UBC 18 -I -C, 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 UBC,
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
00028'7
Ordinance No. 253
Page 8
two -story structures and 15 inches for three -story
structures.
10. Bent reinforcing bard 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" above the bottom of the footing and
consisting of not less than No. 4 bars at 12" 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
so that final connection will not undermine the finished
foundation.

FIRE HAZARD ZONE REQUIREMENTS
Sec. 3601. HIGH FIRE HAZARD AREA DEFINED. For the purpose
of this code, certain locations within the incorporated areas of
the City of Moorpark shall be classified as High Fire Hazard by
the Ventura County Fire Protection District. The High Fire
Hazard Area is defined as any area within 500 feet of
uncultivated brush, grass, or forest - covered land wherein an
authorized representative of said district determines that a
potential fire hazard exists due to the presence of such
flammable growth.
Sec. 3602. CONSTRUCTION REQUIREMENT IN HIGH FIRE HAZARD
AREAS. The purpose of this Section is to provide a minimum
standard for the fire protection of buildings and structures
hereafter erected in proximity to areas of the City where
concentrations of highly flammable brush, grass, or other
combustible growth combined with periods of hot, dry winds create
a high fire hazard and where lives and property may thereby be
endangered.
Buildings or structures hereafter erected, constructed or moved
within or into designated high fire hazard areas shall be one of
the Types of Construction as defined in this Code and shall meet
the requirements of this Section. Although their installation is
encouraged, neither manual nor automatic fire extinguishing
systems or similar water spraying devices may be substituted for
the fire protection set forth herein.

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 twenty -four (24) 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 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 pressure 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.

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.
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 o.c. each way, or equivalent reinforcing.

Page 17
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.
Exception:
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.
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.
3704.2 WASTEWATER. Pool waste shall be disposed of in
accordance with the requirements of the Health Officer.
3704.3 DRYWELLS. Drywells shall not be employed for pool
wastewater 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 as
required by Section 1701 in the UBC shall be provided for
pneumatically placed concrete (gunite) in swimming pools.
Section. 3706. FENCING AND GATES. Any person, firm, or

Page 18
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 four (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.
