BACKGROUND/DISCUSSION
New building standards have been adopted by the State to take effect on January 1,
2017. The State of California Health and Safety Code requires all jurisdictions to
enforce the most recent editions of these 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 stricter than

State standards and are reasonably necessary for reasons relating to local climate,
geology and topography.
The proposed Ordinance (attached), which would take effect on January 1, 2017
concurrently'with the new State standards, includes adoption of the State standards,
along with amendments to specific building code sections dealing with administration
and fees as well as changes to the building standards to improve public safety with
respect especially to earthquakes and fire hazards. The proposed amendments in the
Ordinance were developed and recommended by local building officials and engineers
in conjunction with the Structural Engineers Association of California (SEAC). SEAC,
the City of Los Angeles and the cities of Ventura County as a unified consortium agreed
to recommend adoption of these additional amendments (which exceed the 2016
California Building Standards Codes) given unique climatic, geological and
topographical conditions that impact our local environment pursuant to Section 17958.5
of the Health and Safety Code. The proposed amendments to the 2016 California
Building Code and Residential Code are essentially the same as those made to the
2013 codes by City Ordinance 427, and include stricter standards for foundation design,
swimming pools, expansive soil conditions, fire-restive construction including roof
materials, unreinforced footings, and engineered truss systems.
Because of the proposed amendments, State law requires that the Council direct staff to
advertise a public hearing to be held at least fifteen (15) days prior to consideration of
second reading of the ordinance. Additionally, the City is required to send the
amendments to the State. The City Attorney has reviewed and approved the form of
the Ordinance.
ENVIRONMENTAL DETERMINATION
This ordinance is exempt from the provisions of the California Environmental Quality Act
pursuant to Section 15061(b)(3) of the California Code of Regulations (CEQA
Guidelines) by the general rule that CEQA only applies to "projects" that may have a
significant effect on the environment. The proposed ordinance would amend the
Municipal Code related to building standards necessary to protect health and safety. In
this case, it can be seen with certainty that there is no possibility that the proposed
Ordinance may have a significant impact on the environment.
FISCAL IMPACT
None.
STAFF RECOMMENDATION
Introduce Ordinance No. for first reading, waive full reading, and direct staff to
schedule a public hearing for November 16, 2016, for purposes of providing second
reading and adoption of the ordinance.

NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF MOORPARK,
CALIFORNIA, DOES ORDAIN AS FOLLOWS:
SECTION 1. ENVIRONMENTAL DETERMINATION: The City Council has
reviewed the Community Development Director's determination that this Ordinance
with proposed amendments to Title 15 of the Moorpark Municipal Code is exempt from
the provisions of the California Environmental Quality Act (CEQA) pursuant to Section
15061(b)(3) of the California Code of Regulations (CEQA Guidelines) based on the
general rule that CEQA only applies to "projects" that may have a significant effect on
the environment. This Ordinance would amend the Municipal Code related to building
standards necessary to protect health and safety. In this case, it can be seen with
certainty that there is no possibility that this Ordinance may have a significant impact
on the environment. Based on the foregoing, the City Council, based on its own
independent judgment, finds that the adoption of this Ordinance is exempt from CEQA.
SECTION 2. AMENDMENTS NECESSARY. Pursuant to Section 17958.7 of
the Health and Safety Code of the State of California, the City Council of the City of
Moorpark hereby finds that each amendment to building standards contained in the
2016 Editions of the California Building Code and California Residential Code
made by this Ordinance is reasonably necessary due to local climatic, geological
and topographical conditions as follows:
Local Climatic Conditions — 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. The City also experiences periods of intense rainfall,
which create the need for special drainage precautions.
Local Geological Conditions — The MoorparkNentura County region is a populated
area having buildings constructed over and near fault systems capable of producing
major earthquakes. 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 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.
Local Topographical Conditions — The City contains and is located near hillside brush
areas, so special fire resistive requirements are required in order to reduce fire damage
and fire spread during periods of high temperatures and low humidity. This requires
special construction elements for structures in the City to reduce the threat of fire
damage and fire spread during periods of high temperatures and low humidity.
These local climatic, geological and topographical conditions require specific and
greater protection than is afforded by the 2016 Editions of the California Building Code

15.10 (California Green Building Standards Code), 15.12 (Electrical Code), 15.14
(Plumbing Code), 15.16 (Mechanical Code), 15.18 (Housing Code), 15.20 (California
Energy Code), and 15.22 (California Residential Code) of Title 15 (Buildings and
Construction) of the Moorpark Municipal Code are repealed and replaced in their
entirety as shown in Exhibit B attached hereto and incorporated by reference herein.
SECTION 4. If any section, subsection, sentence, clause, phrase, part or portion
of this Ordinance or any of the Codes adopted herein is for any reason held to be invalid
or unconstitutional by any court of competent jurisdiction, such decision shall not affect
the validity of the remaining portions of this Ordinance or such Codes. The City Council
declares that it would have adopted this Ordinance and such Codes, and each section,
subsection, sentence, clause, phrase, part or portion thereof, irrespective of the fact that
any one or more section, subsections, sentences, clauses, phrases, parts or portions be
declared invalid or unconstitutional.
SECTION 5. This Ordinance shall become effective on January 1, 2017.
SECTION 6. The City Clerk shall certify to the passage and adoption of this
ordinance; shall enter the same in the book of original ordinances of said City; shall make
a minute of the passage and adoption thereof in the records of the proceedings of the City
Council at which the same is passed and adopted; and shall publish notice of adoption in
the manner required by law.

Code and Findings pursuant to Section 17958.7 of the Health and Safety Code
Pursuant to Section 17958.7 of the Health and Safety Code of the State of
California, the City Council of the City of Moorpark hereby finds that each
amendment to the 2016 Editions of the California Building Code and California
Residential Code made by this Ordinance is reasonably necessary due to local
climatic, geological and topographical conditions. These local climatic, geological
and topographical conditions require specific and greater protection than is afforded by
the 2016 Editions of the California Building Code and California Residential Code as
follows:
15.08.030 Foundation design.
Reason for Amendment:
Section 15.08.030 of the Moorpark Municipal Code adds language to Section 1808.6.5

area having buildings constructed over and near fault systems capable of producing
major earthquakes. 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 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 Codes.
15.08.040 Table 1809.7 amended.
Reason for Amendment:
Section 15.08.040 of the Moorpark Municipal Code replaces Table 1807.9 of the 2016
California Building Code in its entirety Code to provide specific requirements to reduce
expansive soil, shrink swell effects on structures constructed on grade in those areas

15.08.050 Swimming pools.
Reason for Amendment:
Section 15.08.050 of the Moorpark Municipal Code adds Section 3109.7 to the 2016
California Building Code to provide specific requirements to reduce expansive soil,
shrink swell effects on swimming pools in those areas of the City with these unique
soils.
Findings:
Local Geological Conditions —The MoorparkNentura County region is a populated
area having buildings constructed over and near fault systems capable of producing
major earthquakes. 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 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 Codes.
15.08.060 Fire hazard zone requirements.
Reason for Amendment:
Section 15.08.060 of the Moorpark Municipal Code adds Chapter 36 to the 2016
California Building Code for the following reasons:
1. Section 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. Section 3602, including 3602.1 through 3602.4, 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.
Findings:
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. The City also experiences periods of intense rainfall, which create the
need for special drainage precautions. These factors require specific and greater
protection than is afforded by California Building Codes.
15.22.030 Footings.
Reason for Amendment:
Section 15.22.030 of the Moorpark Municipal Code amends Sections R403.1.2,
R403.1.3, and R403.1.5 of the 2016 California Residential Code to reduce potential
problems that can result from under-reinforced footings and addresses the under-
performance of plain concrete or under-reinforced concrete during a seismic event.
Findings:

major earthquakes. 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 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 Codes.
15.22.040 TABLE R403.1 Amended.
Reason for Amendment:
Section 15.22.040 of the Moorpark Municipal Code amends Table R403.1 of the 2016
California Residential Code to reduce potential problems that can result from under-
reinforced footings and addresses the under-performance of plain concrete or under-
reinforced concrete during a seismic event.
Findings:
Local Geological Conditions —The MoorparkNentura County region is a populated
area having buildings constructed over and near fault systems capable of producing
major earthquakes. 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 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 Codes.
15.22.050 Foundation Design.
Reason for Amendment:
Section 15.22.050 of the Moorpark Municipal Code adds Section R403.1.8.2 to the
2016 California Residential Code to provide specific requirements to reduce expansive
soil, shrink swell effects on structures constructed on grade in those areas of the City
with these unique soils. This section also 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.
Findings:
Local Geological Conditions—The MoorparkNentura County region is a populated
area having buildings constructed over and near fault systems capable of producing
major earthquakes. 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 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

11
Ordinance No. 440
Page 8
15.22.060 Lateral Support.
Reason for Amendment:
Section 15.22.060 of the Moorpark Municipal Code amends Section R802.8 of the
2016 California Residential Code to reduce potential problems that can result from
poorly designed truss systems and connections.
Findings:
Local Geological Conditions —The Moorpark/Ventura County region is a populated
area having buildings constructed over and near fault systems capable of producing
major earthquakes. 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 factors require specific and greater protection than is afforded by
California Building Codes.
15.22.070 Wood Truss Design.

15.22.080 Roofing
Reason for Amendment:
Section 15.22.080 of the Moorpark Municipal Code amends Section R902.1 of the
2016 California Residential Code to not permit wooden shake or shingle roofs, treated
or untreated. The City is located near hillside brush areas, so special fire resistive
requirements are required in order to reduce fire damage and fire spread during
periods of high temperatures and low humidity. This amendment requires special
construction elements for structures near in the City to reduce the threat of fire damage
and fire spread during periods of high temperatures and low humidity.
Findings:
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.

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
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 three (3)
inches above the bottom of the footing and not less than three (3) inches below the
top of the stem.
4. Slab reinforcement shall be placed at mid-depth and continue to within two (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 twenty-four (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.

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.
3109.7.7.3 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.
Exception:
1. A cutoff wall may be omitted when a deck at least 6 feet wide is installed.
2. Decks less than 4 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.
3109.7.7.4 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.
3109.7.7.5 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 R403.1
1. Pre-moistening is required where specified in Table 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 R403.1.
7. A grade beam not less than 12 inches by 12 inches in cross-sectional area,
reinforced as specified for continuous foundations in Table R403.1, shall be
provided at garage door openings.
8. Foundation stem walls which exceed a height of three (3) 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.

The following language is added to the city's adoption of the California
Residential Code at the location indicated by the section number below:
R403.1.8 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. [NOTE: SECTION R403.1.8 ALREADY EXISTS]

depth-to-thickness ratio exceeding two (2) to one (1) based on nominal
dimensions shall be provided with lateral support at points of bearing to prevent
rotation. For roof rafters with ceiling joists attached per Table R602.3(1), the
depth-thickness ratio for the total assembly shall be determined using the
combined thickness of the rafter plus the attached ceiling joist.
15.22.070 Wood truss design.
Section R802.10.2 of the California Residential Code is replaced in its entirety to
read:
