AGENDA REPORT 1A
TO: Honorable City Council
FROM: David A. Bobardt, Community Development Director l
By: Ray Young, Charles Abbott Associates, Building Official
DATE: November 5, 2010 (CC Meeting of 11/17/2010)
SUBJECT: Consider an Ordinance Amending Title 15 of the Moorpark Municipal
Code by Replacing Chapters 15.04, 15.08, 15.12, 15.14, 15.16, 15.18,
15.20 and 15.22 and Section 15.28.060 in their Entirety and by Adding
Chapter 15.10 as Well as Adopting by Reference and Amending the
Current Editions of Certain Model Codes
BACKGROUND/DISCUSSION
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 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 2010 California Building Standards Codes) given unique climatic,
geological and/or topographical conditions that impact our local environment pursuant to
Section 17958.5 of the Health and Safety Code.
Of particular note in the amendments are the deletion of sections of the new California
Green Building Code dealing with construction waste materials management, which are
addressed in Chapter 8.36 of the Moorpark Municipal Code, with most recent
amendments under consideration for second reading on the November 17, 2010 City

Council agenda. In addition, the State has divided the building code into two sections —
one for non-residential construction and one for residential construction. Amendments
are proposed to the 2010 California Residential Code with respect to footings,
foundations, lateral support, and would truss design to bring the code in line with local
seismic zone requirements. An amendment is proposed to the roofing section of this
code to disallow wood shingles, consistent with the City's current code. Finally, the
code would provide for standardized safety assessment placards to denote the
condition of buildings in the event of an earthquake. Adoption of the placards into
ordinance ensures that they are legally enforceable.
The State Codes take effect on January 1, 2011. These codes include the California
Building Code, 2010 Edition, Volumes 1 and 2, with Appendices C, F, H, I and J;
California Residential Code, 2010 Edition; with Appendices E and H, California
Referenced Standards, 2010 Edition; California Electrical Code, 2010 Edition; California
Plumbing Code, 2010 Edition; California Mechanical Code, 2010 Edition; California
Energy Code, 2010 Edition; California Green Building Code, 2010 Edition; Ventura
County Fire Code, 2010 Edition; California Administrative Code, 2010 Edition;
International Property Maintenance Code, 2009 Edition; and the Gypsum Association
Fire Resistive Manual Nineteenth Edition.
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, if the local jurisdiction has made any substantive changes to the Code, it is
required to send those changes to the state. In this amendment, there are substantive
changes which are recommended to the Code due to the use of the new California
Building Code. The City Attorney has reviewed and approved the draft Ordinance.
STAFF RECOMMENDATION
Introduce Ordinance No. for first reading, and direct staff to schedule a public
hearing and second reading for December 15, 2010.

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 six (6) inches above adjacent grade to prevent surface water from entering the
foundation area.

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" X 12" in cross-sectional area, reinforced as
specified for continuous foundations in Table CBC 1809.7, 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 CBC, or as required by engineering design, whichever is more restrictive.

15.08.040 Fire Hazard Zone Requirements. Chapter 36 is hereby added to
the California Building Code to read:
Chapter 36
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.
3602.1 Roofs. Roof coverings shall be class A, or B as specified in
Section 1505 of the California Building Code, except that no wooden shakes or
shingles, treated or.untreated, shall be permitted.
3602.2 Exterior Walls. Fire-resistive protection of exterior walls and
openings, as determined by location and property, shall be as required by Section 704
in the CBC. Exception: No exterior wall covering of a building shall provide less fire
resistance than that afforded by; 7/8-inch exterior cement plaster; I-inch nominal
thickness solid wood siding; 1/2-inch textured plywood siding having a groove depth of
1/8-inch or less; 7/16-inch hardwood siding 5/8-inch particle board, exterior type 2-M; or
5/8-inch exterior plywood, Texture III, having a groove depth of 1/4-inch or less. Fire-
retardant treated or untreated wood shingle or shake siding shall not be permitted.
3602.3 Underfloor Areas. Where under floor areas are not enclosed by
fire-resistive construction conforming to the requirements of Section 3602.2 above, the
underside of the floor system shall be fire-protected as set forth in Section 3602.4.
124
Ordinance No.
Page 12
3602.4 Projections And Other Building Elements Exposed To Fire.
Architectural projections such as roof overhangs and offsets, balconies and decks, and
other elements of buildings which have combustible structural elements in the
horizontal plane, shall be protected with materials approved for khour fire-resistive
construction on the lower, fire-exposed side and shall have 1-hour fire-resistive
supporting columns unless the details of construction conform to those for heavy timber
as described in Section 602.4 in the CBC.
Exceptions:
1. Combustible structural members in horizontal projections may be unprotected
timbers of size 4-inch x 6-inch or larger when used as rafters or as stair, balcony, or
deck supports or for similar purposes.
2. Heavy timber roof decking at eaves and rakes may be unprotected provided a
fascia of not less than 2-inch nominal thickness and not less in depth than the cut end
of the rafter is installed at the roofs edge.
3. Patios, carports, arbors and open latticework sunshades may be constructed
of any materials allowed by this Code.
4. Balconies and decks 30 inches or more above grade may have flooring of not
less than 2-inch nominal thickness lumber or material of equivalent fire resistance.

3109.6.1 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.
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. Exception:

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.
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.
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.

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 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 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

7. A grade beam not less than 12" X 12" 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.
12. Fireplace footings shall be reinforced with a horizontal grid located 3" above the
