(City council Series)
AN ORDINANCE OF THE CITY COUNCIL OF THE
CITY OF SANTA MONICA
AMENDING SANTA MONICA MUNICIPAL CODE SECTION 8.04.172
REGARDING REPAIR OF POTENTIALLY HAZARDOUS STRUCTURES
AND DECLARING THE PRESENCE OF AN EMERGENCY
WHEREAS, numerous buildings and other structures in the
City of Santa Monica experienced substantial damage due to the
January 17, 1994 Northridge earthquake and its aftershocks; and
WHEREAS, an evaluation of the damage reveals that because
of
construction methods certain structures
are especially
susceptible to damage in the event of major earthquakes and pose a
substantial risk to public health, safety, and welfare; and
WHEREAS, for the reasons set forth above, and for' the
.protection of the public health, safety and welfare, on June 21,
1994, the City Council adopted an Ordinance regarding repair,
reconstruction
and
reinforcement
of
potentially
hazardous
structures;
1
WHEREAS, that Ordinance required, among other things,
that the owner of any soft story structure damaged by the January
17, 1994 Northridge Earthquake or its aftershocks submit an
engineering report to the Building and Safety Division within 120
days of the.effective date of the Ordinance; and
WHEREAS, it took more time than anticipated to identify
and notify owners of their obligation to submit an engineering
report pursuant to the Ordinance due to the excessive number of
such soft story structures damaged by the earthquake; and
WHEREAS, it is consequently necessary to allow additional
time for owners to prepare and submit such engineering reports; and
WHEREAS, absent this amendment, owners would be required
to submit engineering reports by October 21, 1994 which is
insufficient time for compliance;
NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF SANTA
MONICA DOES ORDAIN AS FOLLOWS:
SECTION 1. Santa Monica Municipal Code section 8.04.172 is

As used in
this Section, the following terms shall be
defined as follows:

Ductile
Precast
Concrete
Building. Any structure designed and
constructed with concrete elements that are
cast in other than their final position.
(b) Non Ductile Reinforced Concrete
Building. Any structure designed and
constructed with poured in place reinforced
concrete.
(c) Soft Story Building. Any structure
or portion of a structure classified as soft
story in the Uniform Building Code as adopted
by the city of Santa Monica.
(d) Steel Frame Building. Any structure
designed or constructed with steel frame
3
elements of load bearing and lateral load
resistance systems.
Division 2.00 Determination of Occupant
Load and Building Type. For purposes of this
Section, the occupant load of each structure
shall be determined by the Building Official
in accordance with the Uniform Building Code
as adopted by the City of Santa Monica and
shall be applicable to both vacant and
occupied structures. For purposes of this
Section, the structure type shall be as
defined in the Earthquake Design section of
the Uniform Building Code as adopted by the
City of Santa Monica.
Division 3.00 Scope. The owner of any
structure identified in this section shall,
within the time limits set forth in this
Section, cause the structure to be evaluated,

Division 4.00 Soft Story Construction.
(a) within 120 days of the date of notice
to the owner by the City, but no later than
March 31, 1995, the owner of any soft story
structure damaged by the January 17, 1994
Earthquake or its aftershocks, where the cost
4
of repair is less than 50% of the replacement
value of the structure, shall submit an
engineering report prepared by a licensed
engineer ("engineering 'report") to the
Building and Safety Division, except that any
owner who did not receive notice shall be
granted at least an additional thirty (30) day
extension by City staff from the date the
owner is notified of non-compliance. The
report shall be based on a non-rotational
lateral analysis and shall demonstrate whether
the building complies with the Earthquake
Design Standards contained in the Uniform
Building Code in effect at the time the
structural engineering report is submitted to
the City. If the report concludes the
structure does not comply with the standards,
the structure shall be strengthened within the
timelines of Division 7.00 of this Section and
according to the following standards:
(1) Calculated story drift shall
not exceed 0.04 jRw or 0.005 times the story
height for structures having a fundamental
period of less than 0.7 seconds. For
structures having a fundamental period of 0.7
second or greater, the calculated story drift
5
shall not exceed 0.03/Rw or 0.004 times the
story height.
(2) Use K=2.1, the buckling factor
for a cantilever column, for the design of the
steel columns.
(3) Do not allow the principle of
diaphragm rotation in wood frame buildings to
distribute the design lateral force(s).
(b) Within 120 days of notice to the
owner by the City, the owner of any soft story
structure not damaged by the January 17, 1994
Northridge earthquake or its aftershocks,
shall submit an engineering report to the
Building and Safety Division. The report shall
be based on a non-diaphragm rotational lateral
analysis and shall demonstrate whether the
structure conforms to the Earthquake Design
Standards contained in the Uniform Building
Code as adopted by th~ City of Santa Monica.
If the report concludes the structure does not
comply with the standards, the structure shall
be strengthened within the timelines of
Division 7.00 of this section and according to

submit an engineering report to the Building
and Safety Division. For structures over
three stories in height, the report shall be

7
and for structures three stories or less, the
report shall be based upon a straight lateral
load analysis. The report shall demonstrate
whether the structure conforms to the
Earthquake Design Standards contained in the
Uniform Building Code in effect at the time
