PLUMBING CODE, THE 2010 CALIFORNIA ELECTRICAL CODE,
AND THE 2010 CALIFORNIA MECHANICAL CODE AND THE
UNIFORM CODE FOR THE ABATEMENT OF DANGEROUS
BUILDINGS, 1997 EDITION, AS PUBLISHED BY THE
INTERNATIONAL CODE COUNCIL; AND SCHEDULE A PUBLIC
HEARING FOR DECEMBER 7, 2010
Recommendation: Introduce Ordinance No. 2279 and schedule a
public hearing for December 7, 2010
SUMMARY
The Development Services Department is proposing amendments to the Arcadia
Municipal Code relating to building code regulations for the purpose of complying
with current State requirements and to make changes to current administrative and
technical standards. Every three years, the State of California adopts a new
Building Code with California amendments. The last amendment to the Arcadia
Building Code was adopted on November 6, 2007.
Pursuant to Government Code Section 50022.2, when a local agency adopts a code
by reference, as in this case the California Building Code, etcetera, the prescribed
procedure is for the City Council to schedule a public hearing after the first reading
of the ordinance title. The public hearing is to be held on a future date at which time
the public may address the Council and adoption of the ordinance may then take
place.
DISCUSSION
The 2010 California Building Standards Codes (CBSC) were recently adopted by the
State of California and will become effective on January 1, 2011 for local
enforcement. In addition to the Codes which were adopted three years ago, this
year the State is adopting two new Codes: The "Residential Code" which will pertain
specifically to residential construction, and the "Green Building Standards Code"
which is intended to enhance the design and construction of buildings through the
use of building concepts that will have positive environmental impacts or at least
reduced negative impacts and encourage sustainable construction practices.
Although City staff does not propose any significant technical changes or
amendments to the State Codes, Section 17958 of California's Health and Safety
Code requires the City to make express findings that any current and proposed
technical changes to the State codes by the City are reasonably necessary because
of local climatic, geological or topographical conditions. Because of the State's
requirements, staff reviewed each of the City's existing and proposed technical code
amendments and verified that they meet the intent of the State's Health and Safety
Code. Staff has prepared the requisite Findings, which are attached to and
incorporated as part of the proposed Ordinance No. 2279.
The following summarizes the significant new administrative and technical code
amendments proposed by staff. The purposes of the amendments are stated in the
findings attached to the proposed ordinance.

FISCAL IMPACT
The adoption of the codes and amendments will have no fiscal impact on the City.
ENVIRONMENTAL REVIEW
The proposed amendments to the Arcadia Municipal Code will not have a potential
for causing a significant effect on the environment and is, therefore, not a project per
CEQA Title 14 Sections 15061(b)(3) and 15378(b)(2).

to control erosion. This control shall be permitted to consist of effective planting, erosion
control blankets, soil stabilizers or other means as approved by the Building Official.
EXCEPTION: Erosion control measures need not be provided on cut slopes not
60
subject to erosion due to the erosion - resistant character of the materials as approved by
the Project Consultants, to the satisfaction of the Building Official.
J110.2 Other devices. Where necessary, check dams, cribbing, riprap or other
devices or methods shall be employed to control erosion and provide safety.
J110.3 Planting. The surface of all cut slopes more than 5 feet (1 .5 m) in height
and fill slopes more than 3 feet (9.1 m) in height shall be protected against damage from
erosion by planting with grass or ground cover plants. Slopes exceeding 15 feet (4.6 m) in
vertical height shall also be planted with shrubs, spaced at not to exceed 10 feet (3.0 m)
on centers; or trees, spaced at not to exceed 20 feet (6.1 m) on centers; or a combination
of shrubs and trees at an equivalent spacing, in addition to the grass or ground cover
plants. The plants selected and planting methods used shall be suitable for the soil and
climatic conditions of the site.
Plant material shall be selected which will produce a coverage of permanent
planting to effectively control erosion. Consideration shall be given to deep- rooted plant
material needing limited watering, maintenance, high root to shoot ratio, wind susceptibility
and fire - retardant characteristics. All plant materials must be approved by the Building
Official.
Planting may be modified for the site if specific recommendations are provided by
both the Geotechnical Engineer and a Landscape Architect. Specific recommendations
must consider soils and climatic conditions, irrigation requirements, planting methods, fire
retardant characteristics, water efficiency, maintenance needs, and other regulatory
requirements. Recommendations must include a finding that the alternative planting will
61
provide a permanent and effective method of erosion control. Modifications to planting
must be approved by the Building Official prior to installation.

watering will be acceptable if such hose bibs are installed at conveniently accessible
locations where a hose no longer than 50 feet (15.2 m) is necessary for irrigation.
Irrigation requirements may be modified for the site if specific recommendations are
provided by both the Geotechnical Engineer and a Landscape Architect. Specific
recommendations must consider soils and climatic conditions, plant types, planting
methods, fire retardant characteristics, water efficiency, maintenance needs, and other
regulatory requirements. Recommendations must include a finding that the alternative
irrigation method will sustain the proposed planting and provide a permanent and effective
method of erosion control. Modifications for irrigation systems must be approved by the
Building Official prior to installation.

FINDINGS OF FACT
Pursuant to the 2010 Edition of the California Building Code Preface, the
repost contained herein shall be submitted as the Findings of Fact
document with regard to Article III of the City of Arcadia Municipal Code,
Ordinance No. 2279 as adopted by the City of Arcadia. Under this
Ordinance specific amendments have been established, which are more
restrictive in nature than those sections adopted by the California Building
Standards Code.
The amendments to the California Building Code, 2010 Edition have been
recognized by the City of Arcadia to address the Building problem (s) and
maintain an environment, which will afford a level of fire and life safety to
its citizens and guests.
Under provisions of California Building Code Preface, local amendments
shall be based on climatic, geographical or topographical conditions. The
Findings of Facts contained herein shall address each of these situations
and shall present the local situation, which singularly or in combination
cause the established amendments to be adopted.
Climatic: The City of Arcadia is located in the County of Los Angeles,
and is subject to long periods of dry, hot and windy climates, which
increase the chance of a fire occurring and predispose the City to large
destructive fires. These dry climatic conditions and winds contribute to the
rapid spread of even small fires originating in moderate density housing or
vegetation. These fires spread very quickly and create a need for increased
levels for fire prevention and protection. This added protection will
supplement normal fire department response available and provide
immediate protection for life and safety of occupants during fire
occurrences. The warm, dry climate is conducive to swimming pools
which creates a higher probability of child drowning where pools are
unprotected.
Geographical: The geographic layout and contours of the City of Arcadia
create barriers for accessibility for fire suppression forces. Due to the
City's close proximity to major fault lines, there is a significant possibility
for multiple fires spreading out of control due to ruptured gas lines and
multiple structural collapses. Because of the major earthquake hazard, and
due to some older nonconforming buildings, it is necessary during the new
construction or building renovation to use the City ordinance to control and
minimize conditions hazardous to life and property, which may result from
fire, hazardous materials or an explosion.
EXHIBIT "A"
2279
Topographical: The water supply (domestic and fire flow) system within
the City is directly affected by the topographical layout of Arcadia. The
distribution system consists of high -low pressure and gravity systems
zones, which carry the water from various reservoirs and storage tanks to
different zones via water pipes. These street mains consist of high - pressure
lines and low pressure lines where the pressure and flows are adequate in
most of the areas of the city. There are certain areas in the southern portion
of the City with static pressures of 40 psi., and in the northern portion as
low as 20 psi. This variation of pressure causes major problems to
development, as well as fire suppression forces.
As a result of the Findings of Fact, which identified the various climatic,
geographical, and topographical elements, the requirements established by
the City of Arcadia Building Department within the adopted Ordinance No.
2279 are considered reasonable and necessary modifications to the
California Building Code based upon local conditions.
While it is clearly understood that the adoption of such regulations may not
prevent the incidents of fire, and/or structural failure it is further noted that
with the implementation of these various regulations and /or requirements it
may serve to reduce the severity and potential loss of life and property.
The City of Arcadia Building Department submits these Findings of Fact
and request acceptance of these as defined in the California Building Code
Preface.
