A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF DIAMOND
BAR MAKING EXPRESS FINDINGS AND DETERMINATIONS THAT
' MODIFICATIONS TO THE CALIFORNIA BUILDING CODE, CALIFORNIA
PLUMBING CODE, AND CALIFORNIA ELECTRICAL CODE, AS
ADOPTED BY ORDINANCE NO. 09 (20021 ARE REASONABLY
NECESSARY BECAUSE OF LOCAL CLIMATIC, GEOLOGICAL OR
TOPOGRAPHICAL CONDITIONS,
A. Recitals.
(i) California Health and Safety Code Section 17922 requires all cities to
adopt, as the City Building Standards Code, the State Building Standards Code adopted
pursuant to the provisions of Chapter 4 of Part 2.5 of Division 13 of the California Health
and Safety Code.
(ii) Section 17958.5 of the California Health and Safety Code provides, in
pertinent part, as follows:
"...a city or county may make such changes or modifications in the
requirements contained in the provisions published in the State Building
Standards Code and the other regulations adopted pursuant to Section
17922 as it determines, pursuant to the provisions of Section 17958.7, are
reasonably necessary because of local climatic, geological or
topographical conditions."
(iii) Prior to making the modification permitted under Section 17958.5 of
the California Health and Safety Code, this Council is required to make an express
finding that such modifications or changes are reasonably necessary.
(iv) This Council desires to amend the provisions of sections 1806.10,
1503, 1504, Table No. 15A, 904.22, and appendix Chapter 33 of the "California Building
Code", 2001 Edition.
(v) This Council desires to amend the provisions of Sections 320 and
722.6 of the "California Plumbing Code", 2001 Edition.
(vi) This Council desires to amend the provisions of Section 110-14, 336-
3, Section 336-4 and Table No. 300.5 of the "California Electrical Code", 2001 Edition.
(vii) All legal prerequisites to the adoption of this Resolution have
occurred.
B. Resolution.
NOW, THEREFORE, be it found, determined and resolved as follows:
1. In all respects as set forth in the Recitals, Part A, of this Resolution.
2. This Council does hereby expressly find and determine that
' the amendments set forth in Ordinance 09 (2002) amending
Section 1806.10 and appendix Chapter 33 of the "California
Building Code," 2001 Edition, and adding subsection 722.6 of the
Res. 2002-67
"California Plumbing Code," 2001 Edition, are reasonably
necessary because of local climatic, geological or topographic
conditions. This express finding is supported and based upon the
following more specific findings and determinations:
a. The hillsides in Diamond Bar are composed of Puente Formation,
and similar weak geological materials, while neighboring flatland areas are composed of
more stable fill and alluvial materials. These materials may be naturally unstable or
weak in terms of physical support. These highly expansive soil conditions are
vulnerable to earth movement.
b. The City of Diamond Bar experiences diverse temperatures, which
promotes expansion and contraction of the soil. This condition is very damaging to
expansive type soil.
C. Because of the above-described climatic and geological conditions,
the City of Diamond Bar requires special engineering to support habitable structures
within the unstable soil areas and requires additional measures to be taken in
connection with excavation and grading on private properties. This will decrease
possible damage due to natural earth expansion and seismic activity.
3. This Council does hereby expressly find and determine that the
amendments set forth in Ordinance No. 09 (2002), amending Sections 1503, 1504, and
Table No. 15A of the "California Building Code", 2002 Edition, are reasonably
necessary because of local climatic, geological or topographic conditions. This express
finding is supported and based upon the following more specific findings and
determinations:
a. Located throughout the City of Diamond Bar, as well as in the
surrounding cities, are numerous concentrations of structures which have roofs
constructed of thinly cut pieces of wood, otherwise known as untreated shakes, as well
as untreated wood shingles. These untreated wood shakes and shingles are extremely
combustible in nature.
b. The City of Diamond Bar, as well as the surrounding cities, is
located in an area climatically classified as "arid" and prone to winds of high velocity.
Moreover, due to the and nature of the area, the weather during the windy periods tends
to be very warm and dry. The dry weather conditions are very hazardous to the
surrounding undeveloped hillsides and wild lands which neighbor highly populated
areas.
C. Because of the above-described climatic and meteorological
conditions, the City of Diamond Bar and the surrounding cities have historically suffered
from occasional structural and brush fires. These have often been difficult to control
due to the high velocity, dry winds carrying sparks and cinders to surrounding structures
with roofs constructed as described in paragraph 3.a. above.
4. This Council does hereby expressly find and determine that the
amendments set forth in Ordinance No. 09 (2002), amending Sections 904.22 of the
"California Building Code", 2001 Edition, are reasonably necessary because of local
Res. 2002-67
climatic, geological, or topographic conditions. This express finding is supported and
based upon the following more specific findings and determinations:
a. The City of Diamond Bar is located in a seismically active area and
' is in close proximity to earthquake fault zones (Whittier fault, just south of Tonner
Canyon; Chino fault passes within a mile of the city's eastern boundary), and it is
reasonably foreseeable that an earthquake would render the City of Diamond Baer
particularly vulnerable to devastation. Further, the City of Diamond Bar is bisected by
major freeways, located primarily in a north -south direction. Substantial number of flood
control facilities additionally exist, as well as freeway overpasses and major railroad
right-of-ways.
b. Because of the above-described geological conditions within the
city, and the substantial amount of freeway, railroad, and flood control facilities
throughout the community, the City of Diamond Bar, in the event of an earthquake, may
be unable to dispatch an adequate number of fire personnel and apparatus to suppress
fires and conduct rescue operations. Moreover, the conditions within Diamond Bar
likewise occur in surrounding communities, hereby rendering mutual aid assistance;
problematic, at best.
C. Furthermore, climatic conditions within the community render it
extremely likely that, in the event of seasonal high winds and earthquake occurring, this
County Fire Department would be unable to suppress numerous fires occurring
throughout the community. Installation of sprinkler systems in buildings above threle
stories in height will enable suppression activities to be directed to those areas, which
are unprotected in the event of earthquake activity.
5. This Council does hereby expressly find and determine that the
amendments set forth in Ordinance No. 09 2002 , amending Section 318.0 of the
"California Plumbing Code", 2001 Edition, are reasonably necessary because of local
climatic, geological or topographical conditions. This express finding is supported and
based upon the following more specific findings and determinations:
a. The City of Diamond Bar is subject to drought conditions. Its water
provider, the Metropolitan Water District, may restrict local water supplies in such cases
and impose surcharges on water supplied in excess of these levels. As water supplies
are restricted further and the price of water rises, the City of Diamond Bar will find it
difficult to maintain hillside erosion control and the general quality of life in our
community will suffer.
b. Because of the above-described climatic condition affecting the City
of Diamond Bar, the need for alternative methods of providing landscape irrigation is
enormous. The use of reclaimed water will help to meet this demand, now and in the
future.
6. This Council does hereby expressly find and determine that the
amendments set forth in Ordinance No. 09 2002 , amending Sections 110-14, 336-3,
336-4 and Table No. 300.5 of the "California Electrical Code", 2001 Edition, are
reasonably necessary because of local climatic, geological or topographical conditions.
' This express finding is supported and based upon the following more specific findings
and determinations:
Res. 2002-67
a. As found in paragraph 4.b., the City of Diamond Bar is located in a
seismically active area and is in close proximity to earthquake fault zones (Whittier fault,
just south of Tonner Canyon: Chino fault passes within a mile of the city's eastern
boundary), and it is reasonably foreseeable that an earthquake would render the City of
Diamond Bar particularly vulnerable to devastation. Further, the City of Diamond Bar is
bisected by major freeways, located primarily in a north -south direction. Substantial
number of flood control facilities additionally exist, as well as freeway overpasses and
major railroad right-of-ways.
b. Because of the above-described geological conditions within the
city, and the substantial amount of freeway, railroad, and flood control facilities
throughout the community, the City of Diamond Bar, in the event of an earthquake, may
be unable to dispatch an inadequate number of fire personnel and apparatus to
suppress fires and conduct rescue operations. Moreover, the conditions within
Diamond Bar likewise occur in surrounding communities, hereby rendering mutual aid
assistance problematic, at best.
C. Furthermore, as found in paragraph, 2.b., of this Resolution,
climatic conditions within the community render it extremely likely that in the event of
seasonal high winds and earthquake occurring, the County Fire Department would be
unable to suppress numerous fires occurring throughout the community. Therefore
protection of electrical wiring is essential in the above described events and this
protection is magnified in high occupancy buildings.
ADOPTED AND APPROVED this 3rd day of, September, 2002.
