with amendments thereto.
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
Ordinance No. 289
Page 2
construction, which makes modifications to the California
Building Code relating to swimming pools desirable to adequately
protect small children: from drowning hazards. The City alsc
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.
2. 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.
3. MMC §§ 1804.7.1 and Table i8 -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.
4. MMC §§ 1804.7.1 provides special criteria for storm
water drainage on lots to mitigate the effects of runoff
Ordinance No. 289
Page 3
associated with intense rainfall, for structures located in flat
land developments as well as hillside areas.
5. MMC §§ 3602.1 modifies code language to provide fire
retardant roofing in order to address periods of low humidity and
high winds.
6. MMC §§ 15.08.050 and Table 23- II -I -1 reduces hold -down
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
oiaced not less than 3 inches above the bottom of the footing and
not mess than 3 inches below the top of the stern.
4. Slab reinforcement shall be placed at mid -depth and
continue to within two inches 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.
Ordinance No. 289
Page 9
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
so that final connection will not undermine the finished
foundation.
Section 1804.7.1. When buildings are located on expansive
soli 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.
