AN ORDINANCE OF THE CITY COUNCIL OF THE
CITY OF ORANGE AMENDING SPECIFIED
SECTIONS OF TITLE 15 OF THE ORANGE
MUNICIPAL CODE RELATING TO
CONSTRUCTION CODES AND ADOPTING THE
2007 EDITION OF THE CALIFORNIA CODES,
RELATED MODEL CODES AND APPENDICES AND
AMENDMENTS THERETO.
WHEREAS, due to Fire Department logistical limitations and local high winds, the
requirement of the high rise buildings in Building Code Section 202 is amended to apply to
buildings over 55 feet high instead of over 75 feet high; and
WHEREAS, due to Fire Department logistical limitation and local high winds, the
requirement of high-rise buildings for standby and emergency power loads in Building Code
Sections 403.10.2 and 403.11.1 are revised to place smoke proof enclosures in the emergency
power category; and
WHEREAS, due to Fire Department logistical limitation, the Fire Code requirement in
for emergency helicopter landing facilities on high-rises is added to Building Code Section
412.5.1 to coordinate enforcement; and
WHEREAS, due to Fire Department logistical limitation and local high winds Building
Code Section 904 is modified to apply City of Orange Fire Ordinance (Chapter 15.32) building
sprinkler amendments; and
WHEREAS, due to serious hazard of rapid fire spread in local high winds, the use of
untreated wood roofs and minimally protective roof assemblies and coverings permitted by the
Building Code Section 1505 are prohibited for new buildings and re-roofing of existing
buildings and are in part, a response to a recent Grand Jury Investigation Report; and
WHEREAS, the 2007 California Building Code (CBC) does not provide requirements
for separation distances between adjacent buildings to allow for independent building
displacement due to earthquake ground motions and amendments are necessary due to the
frequency and potential magnitude of earthquake activity in Orange; and
WHEREAS, the minimum base shear required by the 2007 CBC is specified in ASCE 7-
OS as referenced in the 2006 International Building Code and is significantly less than that
required by previous editions of the CBC and ASCE 7 and due to the frequency and potential
magnitude of earthquake activity in Orange, provides insufficient levels of protection in
structural design and the amendment will provide the same level of protection in structural
design for new high-rise buildings as State buildings; and
WHEREAS, the CBC has insufficient information in the American Society of testing
Materials (ASTM) standards referenced in ASCE 7 regarding prescriptive design requirements
for ceiling suspension systems for seismic loads and thus, needs amending; and
WHEREAS, the 2007 CBC provisions for concrete design are specified in American
Concrete Institute (ACI) 318-OS as referenced by the 2006 IBC. The ACI 318-OS provisions for
alternate slender wall design commonly used for tilt-up concrete walls significantly under-
estimates service load deflection for some cases. The proposed code amendment is included in
ACI 318-08 and is consistent with current practice in California based on previous Uniform
Building Code provisions that better estimate service load deflections; and
WHEREAS, because of the risk of delays in fire rescue response time due to traffic
congestion and due to the high number of swimming pools within close proximity to small
children because of local climate which makes pool ownership desirable, pool barriers are
necessary and the proposed amendments are necessary to correct an administrative error in the
State's adoption to be consistent with barrier requirements currently enforced in the City; and
WAEREAS, an amendment is necessary to Electrical Code Article (310.2(B) & 310.16)
due to the fact that improper installation creates a potential fire hazard and aluminum wire size
No. 6 and smaller requires greater precision and care for proper installation.
NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF ORANGE DOES
ORDAIN AS FOLLOWS:
SF,CTinN T—Rnilding('.de

M —I Equation 16-45)
where ,,,aX is the calculated maximum displacement at Level x, and may be taken as 1.2
times the average of the displacement at the extreme points ofthe structure at level x.
Adjacent buildings on the same property shall be separated by at least a distance MT,
where
2 2
MT — M 1 + M2 Equation 16-46)
and M and MZ are the maximum inelastic response displacements of the adjacent
