FROM: Barry K. Hogan, Community Development Direo
Prepared By: Laura Stringer, Senior Manag ct n Analyst
DATE: September 19, 2002 (CC Meeting of 10/2/02) P
SUBJECT: Consider an Ordinance Amending Moorpark Municipal Code
Title 15 - Building and Construction, by Amending
Chapters 15.04, 15.08, 15.12, 15.14, 15.16, 15.18, and
15.20; Adopting By Reference and Amending the Current
Editions of Certain Model Codes
BACKGROUND
The State of California Health and Safety Code requires all
jurisdictions to enforce the most recent editions of various
building standards. Although the State requires the enforcement
of certain standards, it allows the City to amend these standards
in order to address local concerns. The State, however, does,
limit the City's ability to amend the prescribed building
standards to amendments that are reasonably necessary for reasons
relating to local climate, geology and topography.
The proposed Ordinance includes such amendments to Municipal Code
Sections dealing with seismic upgrades, pool safety and fencing,
and foundation requirements for expansive soil. The findings to
establish the reasonable necessity of these amendments are
included in Section 1. of the Ordinance.
The State - mandated standards, along with any amendments, must be
adopted by November 1, 2002. If the City fails to adopt the
attached Ordinance with the recommended amendments to Title 15,
the State - mandated standards will then automatically go into
effect, and any local amendments will be lost. The building
standards which are required to be adopted at this time are
contained in Uniform Building Code, 1997 Edition, Volumes 1, 2
&3, with Appendix; including the Fire Resistive Design Manual,
Fourteenth Edition, dated April 1994; National Electrical Code,

1997 Edition; Uniform Administrative Code, 1997 Edition.
DISCUSSION
Amendments to the State - mandated codes fall into two categories;
amendments to actual building standards and amendments to
administrative provisions. Proposed amendments to the actual
building standards include:
Building Standards Amendments:
• Structural seismic upgrades.
• Foundation requirements for expansive soil.
• Pool fencing requirements.
Plumbing Standards Amendments:
• Requirements for floor drains in semi - private swimming
pool restrooms.
Housing Standards Amendments:
• Adoption of Uniform Housing Code and Uniform Code for
the Abatement of Dangerous Buildings
• List of conditions which constitute hazardous
conditions is changed to reflect the list in the
California Health and Safety Code.
Proposed amendments to the administrative provisions include:
Arlmi ni atrati vP qtanriArrl-, Amtnr3mont -, -
• Removal of the administrative section of the various
building standards and adoption of the Uniform
Administrative Code.
• Building plan review and permit fees are set by
resolution of the City Council to allow periodic review
and adjustment of plan review and permit fees without
requiring a code amendment.
• Clarification to assure that contract service providers
enjoy the same immunity from lawsuits as their public
employee counterparts.

The proposed amendments to Moorpark Municipal Code Title 15 are
necessary to allow for local conditions and to provide
consistency in the administrative provisions. These amendments
reflect the current language contained in Chapters 15.04, 15.08,
15.12, 15.14, 15.16, 15.18, and 15.20, but must be adopted again,
along with the various State - mandated codes, to continue to be
effective.

NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF MOORPARK
DOES ORDAIN AS FOLLOWS:
SECTION 1. Pursuant to the requirements of Health & Safety
Code § 17958.7, the City Council finds that there are local
geographical conditions justifying the California Building Code
amendments set forth below:
1. Climatic. The local climate is characterized by
periods of high temperatures accompanied by low humidity and high
winds each year. These conditions could create an environment in
which the fire department may have great difficulty in
controlling fires occurring in hillside brush areas as well as
structures not having built -in fire protection. Further, the
warm climate encourages the proliferation of swimming pool

construction which makes modifications to the California Building
Code relating to swimming pools desirable to adequately protect
small children from drowning hazards. The City also experiences
periods of intense rainfall, which create the need for special
drainage precautions.
2. Geological. The City is located in an area with
expansive soils and areas subject to flood hazards including
hillsides that are subject to mud flows and unstable soils. These
conditions, combined with the geological characteristics of the
area, which includes proximity to active earthquake fault zones,
require that special foundation considerations and soils analysis
requirements must be in place to provide a reasonable degree of
structural integrity for buildings to prevent injury to building
occupants, neighbors, and persons using public property. These
factors require specific and greater protection than is afforded
by California Building Code.
3. Topographical. The City has hillside and flat land
developments that require special drainage precautions, as well
as a system of roadways and highways that generate traffic noise.
Structures would be subject to water damage without special
requirements addressing site drainage.
These local climatic, geologic, and topographic conditions
make modifications and changes to the 2001 Edition of the
California Building Code reasonably necessary to provide
sufficient and effective protection of life, health and property.
Specifically, these amendments are reflected in the Moorpark
Municipal Code ( "MMC ") sections summarized below:
1. MMC § 3601 establishes boundaries within the City for
structures near hillside brush areas, so special fire resistive
requirements may be required in order to reduce fire damage and
fire spread during periods of high temperatures and low humidity.
3. MMC § 3602 requires special construction elements for
structures near hillside brush areas to reduce the threat of fire
damage and fire spread during periods of high temperatures and
low humidity.
4. MMC §§ 1804.7.1 and Table 18 -I -C provide specific
requirements to reduce expansive soil, shrink swell affects on
structures constructed on grade in those areas of the City with
these unique soils.
5. MMC §§ 1804.7.1 provides special criteria for storm
water drainage on lots to mitigate the effects of runoff

associated with intense rainfall, for structures located in flat
land developments as well as hillside areas.
6. MMC §§ 3602.1 modify code language to provide fire
retardant roofing in order to address periods of low humidity and
high winds.
7. MMC §§ 15.08.050 and Table 23- II -I -1 Reduces hold -own
values and shear wall capacities for a greater margin of safety
SECTION 2. That Title 15 of the Moorpark Municipal Code is
amended to read as follows;

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 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" 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.
Section 1804.7.1. When buildings are located on expansive
soil having an expansion index greater than 50, gutters,
downspouts, piping, and /or other non - erosive devices shall be
provided to collect and conduct rain water to pervious areas such
as yards, open channels, or vegetated areas. Routing rooftop
runoff via yard drains to the roadway or the storm water
conveyance system shall not be permitted.

1. Pre - moistening is required where specified in Table UBC I8 -1 -C in order to achieve maximum and uniform expansion of soil prior to construction, thus limiting 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 six (6) inches above adjacent grade to prevent surface water from entering the foundation area.
3. Reinforcement for continuous foundations shall bet 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 slab mid -depth and continue to within two inches of the exterior face of the exterior footing walls.
5. Moisture content shall be maintained until foundations and piers are poured and a vapor barrier is installed. Test shall be taken with in 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 1806.3, shall be designed and constructed as specified for perimeter footings in Table UBC 18.1 -C.
7. A grade beam not less than 12" x 12" in cross - sectional area, reinforced as specified in Table UBC 18.1 -C shall be provided at garage door openings.
8. Foundation stem walls which exceed a height of three times the stem thickness above the lowest adjacent grade shall be reinforced in accordance with Chapters 18 and 19 in the UBC, or as required by engineering
design, which ever 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 twelve inches for one and two story structures and fifteen
inches for three -story structures.
10. Bent reinforcing bars between exterior footing and slab shall be omitted when the floor is designed as an independent, "floating" slab.
It. 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.

(76mm) nominal or wider and nails on each side shall be staggered.
3. Framing at adjoining panel edges shall be 3 inch (76mm) nominal or wider and nails shall be staggered where nails are spaced 2 inches (51mm) on center.
4 The values for 3/8 -inch (9.5mm) and 7/16 -inch (I Imm) panels applied direct to framing may be increased to the values shown for 15132 -inch (12mm) panels, provided studs are spaced a maximum of 16 (406mm)
inches on center and panels are applied with long dimensions across studs.
5. Framing at adjoining panel edges shall be 3 inch (76mm) nominal or wider and nails shall be staggered where 10d nails having penetration into framing of more than 1 518 inches (41mm) are spaced 3 inches (76mm)
or less on center.
6. For plywood shear walls rated at more than 300 pounds per foot, 3 inch (76mm) nominal members shall be provided at all panel edges and boundaries. The minimum edge distance for nailing at these members shall
be I/2 -inch.
7. The shear values listed in this table shall be reduced to 75 percent for short term seismic loading.

Chapter 36 is added to the Uniform Building Code to
read:
CHAPTER 36
FIRE HAZARD ZONE REQUIREMENTS
Sec. 3601. HIGH FIRE HAZARD AREA DE-
FINED. 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 uncultivat-
ed 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 concen-
trations 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.
3602.1 ROOFS. Roof coverings shall be class A,
or B as specified in Section 1504 of the Uniform Build-
ing Code, except that no wooden shakes or shingles,
treated or untreated, shall be permitted.
3602.2 EXTERIOR WALLS. Fire - resistive protec-

15.08.110 Swimming pools.
Chapter 37 is added to the Uniform Building Code to
read:
CHAPTER 37
SWIMMING POOLS
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 CONSTRUC-
TION.
3702.1 GENERAL. Pool design and construction
shall be in accordance with accepted engineering prac-
tice, shall be in conformity with applicable provisions
of the adopted building, electrical, plumbing, and me-
chanical codes, and shall be structurally suitable for
the soil, topographic, and geologic conditions prevailing
at the construction site.
3702.2 EXPANSIVE SOIL DESIGN. Pools con-
structed 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
253 (Moorpark 7 -99)
15.08.110
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.
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 equip-
ment 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 five 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 batfiers 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
(Moorpark 7 -99)
254
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.
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.
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 in-
creased 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 9I 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.
C'. Z�lok"Io
3704.2 WASTEWATER. Pool waste shall be dis-
posed of in accordance with the requirements of the
Health Officer.
3704.3 DRYWELLS. Drywells shall not be em-
ployed for pool wastewater disposal except when specifi-
cally 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 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 gape therein shall
be no larger than four (4) inches wide except for open-
ings 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.
Exceptions:
1. Doors in Group R, Division 1 and 3 occupancies
which form part of a pool enclosure.
2. Gates used primarily for ingress and egress of
equipment but not persons to the pool area, and which
are kept padlocked when not in use.
254 -1
15.08.1 10
Required latching devices shall be installed not less
than four feet above ground level and on the waterside
of the gate.
The Building Official may make modifications and
accept alternatives to the fencing requirements in individ-
ual cases upon a showing of good cause with respect
to the height, nature or location of the fence, wall, gates,
or latches, or the necessity therefore, provided that
protection is not reduced thereby.
