G. Earthquake Faults.
1. General. The construction of a building or structure near a known active earthquake fault and
regulated by this code shall be permitted as set forth in this section.
2. Scope. The provisions of this section shall apply only to permits for buildings or structures on
individual lots or parcels and are not intended to be supplementary to geologic investigations
required to qualify divisions of land as set forth in the Uniform Development Code of the City of
Santa Clarita.

by the California State Board of Registration for Geologists and Geophysicists to practice geology
in California.
4. Known Active Earthquake Faults. For the purpose of this section, known active earthquake
faults are those faults which have had displacement within Holocene time (approximately the last
11,000 years) as defined in the most current issue of Special Publication 42 of the California
Division of Mines and Geology.
5. Earthquake Fault Maps. Special studies zone maps within the City of Santa Clarity prepared
under Sections 2622 and 2623 of the California Resources Code which show traces of earthquake
faults are declared to be, on the date of official issues, a part of this code. Special studies zones
maps revised under the above sections of the California Resources Code shall, on the date of their
official issue, supersede previously issued maps. Copies of each of the above maps shall be
available for examination by the public at the City. The City shall maintain maps available to the
public showing the location of known active earthquake faults. In the absence of additional
information, the location of known active earthquake faults shall be as shown on special studies
zones maps.
6. Construction Limitations. No building or structure shall be constructed over or upon the trace of
a known active earthquake fault in the following cases:
a. When the proposed building is within 50 feet of that line designated as the location of a
known active earthquake fault on the aforementioned maps.
b. When the proposed building is within 50 feet of the most probable ground location of the
trace of a known active earthquake fault shown on the aforementioned maps.
In cases when a geologist has not made such a determination, the City may require the excavation
- • of a trench, as a subsurface.exploration for the purpose of determining the absence of a known
active earthquake fault. Such a trench will be required if a lack of distinguishable fault features in
the vicinity prevents the City from determining by a site examination, review of available aerial
photographs, or by other [Weans that the fault trace does not underlie the proposed building. The
trench shall be approximately perpendicular to the most probable direction of the fault trace, at
least 18 inches wide, and at least five feet in depth measured from natural grade, or to a depth
satisfactory to the City.
The trench must be accessible for mapping and inspection by the City, when requested, and meet
the requirements of Title 8 of the California Code of Regulations, Construction Safety Orders.
The trench need not extend further than the full width of the proposed structure plus five feet
beyond the traversed exterior walls. A known active earthquake fault shall be presumed
nonexistent if an exposure is not found in the walls or floor of the trench. The City may require a
more extensive investigation by a geologist as evidence to the absence of a known active
earthquake fault prior to the issuance of a building permit

1804 060. Division VI—Seismic Design Provisions for Hillside Buildings is added to Chapter 16, beginning
and ending with Section 1637, to read as follows:
"1637 Seismic Design Provisions for Hillside Buildings.
1637.1 Purpose. The purpose of this Section is to establish minimum regulations for the design and
construction of new buildings and additions to existing buildings when constructing such buildings on or
into slopes steeper than three horizontal to one vertical. These regulations establish minimum standards for
seismic force resistance to reduce the risk of injury or loss of life in the event of earthquakes.
1637.2 Scope. The provisions of this Section shall apply to the design of the lateral force resisting system
for hillside buildings at and below the base level diaphragm. The design of the lateral force resisting
system above the base level diaphragm shall be in accordance with the provisions for seismic and wind
design as required elsewhere in this Division.
EXCEPTION: Non -habitable accessory buildings and decks not supporting or supported from the
main building are exempt from these regulations.
1637.3 Defmitions. For the purposes of this Section certain terms are defined as follows:
BASE LEVEL DIAPHRAGM is the floor at, or closest to, the top of the highest level of the
foundation.
DIAPHRAGM ANCHORS are assemblies that connect a diaphragm to the adjacent foundation at the
uphill diaphragm edge.
DOWNHILL DIRECTION is the descending direction of the slope approximately perpendicular to
the slope contours.
FOUNDATION is concrete or masonry which supports a building, including footings, stem walls,
retaining walls, and grade beams.
FOUNDATION EXTENDING IN THE DOWNHILL DIRECTION is a foundation running
downhill and approximately perpendicular to the uphill foundation.
HILLSIDE BUILDING is any building or portion thereof constructed on or into a slope steeper than
three horizontal to one vertical. If only a portion of the building is supported on or into the slope, these
regulations apply to the entire building.
PRIMARY ANCHORS are diaphragm anchors designed for and providing a direct connection as
described in Sections 1637.5 and 1637.7.3 between the diaphragm and the uphill foundation.
SECONDARY ANCHORS am diaphragm anchors designed for and providing a redundant - - -
diaphragm to foundation connection, as described in Sections 1637.6 and 1637.7.4.
UPHILL DIAPHRAGM EDGE is the edge of the diaphragm adjacent and closest to the highest
ground level at the perimeter of the diaphragm.
UPHILL FOUNDATION is the foundation parallel and closest to the uphill diaphragm edge.
1637A Analysis and Design.
1637.4.1 General. Every hillside building within the scope of this Section shall be analyzed, designed, and
constructed in accordance with the provisions of this Division. When the code -prescribed wind design
produces greater effects, the wind design shall govern, but detailing requirements and limitations
prescribed in this and referenced sections shall be followed.
1637A.2 Base Level Diaphragm -Down hill Direction. The following provisions shall apply to the
seismic analysis and design of the connections for the base level diaphragm in the downhill direction.
1637A.2.1 Base for Lateral Force Design Defined. For seismic forces acting in the downhill direction,
the base of the building shall be the floor at or closest to the top of the highest level of the foundation.
Page 18 of 77
1637A.2.2 Base Shear. In developing the base shear for seismic design, the structural system factor (Rw)
shall not exceed 4.5 for bearing wall and building frame systems. The total base shear shall include the
forces tributary to the base level diaphragm including forces from the base level diaphragm.
1637.5 Base Shear Resistance -Primary Anchors.
1637.5.1 General. The base shear in the downhill direction shall be resisted through primary anchor; from
diaphragm struts provided in the base level diaphragm to the foundation.
16375.2 Location of Primary Anchors. A primacy anchor and diaphragm strut shall be provided in line
with each foundation extending in the downhill direction. Primary anchors and diaphragm struts shall also
be provided where interior vertical lateral force resisting elements occur above and in contact with the
base level diaphragm. The spacing of primary anchors and diaphragm struts or collectors shall in no case
exceed 30 feet.
163753 Design of Primary Anchors and Diaphragm Struts. Primary anchors and diaphragm struts
shall be designed in accordance with the requirements of Section 1637.8.
16375.4 Limitations. The following lateral force resisting elements shall not be designed to resist seismic
forces below the base level diaphragm in the downhill direction:
1. Wood structural panel wall sheathing.
2. Cement plaster and lath
3. Gypsum wallboard
4. Tension only braced frames
Braced frames designed in accordance with the requirements of Section 2213.8 of this code may be used
to transfer forces from the primary anchors and diaphragm struts to the foundation provided lateral forces
do not induce flexural stresses in any member of the frame or in the diaphragm struts. Deflections of
frames shall account for the variation in slope of diagonal members when the frame is not rectangular.
1637.6 Base Shear Resistance -Secondary Anchors.
1637.6.1 General. In addition to the primary anchors required by Section 1637.5, the base shear in the
downhill direction shall be resisted through secondary anchors in the uphill foundation connected to,
diaphragm struts in the base level diaphragm
EXCEPTION: Secondary anchors are not required where foundations extending in the downhill
direction spaced at not more than 30 feet on center extend up to and are directly connected to the base
level diaphragm for at least 70% of the diaphragm depth.
1637.6.2 Secondary Anchor Capacity and Spacing. Secondary anchors at the base level diaphragm
shall be designed for a minimum force equal to the base shear, including forces tributary to the base level
diaphragm, but not less than 600 pounds per lineal foot. The secondary anchors shall be uniformly
distributed along the uphill diaphragm edge and shall be spaced a maximum of four feet on center.
1637.63 Design. Secondary anchors and diaphragm struts shall be designed in accordance with Section
1637.8
1637.7 Diaphragms Below the Base Level -Downhill Direction. The following provisions shall apply to
the lateral analysis and design of the connections for all diaphragms below the base level diaphragm in the
downhill direction.
Page 19 of 77
1637.7.1 Diaphragm Defined. For the purposes of Section 1637.7 every floor level below the base level
diaphragm shall be designed as a diaphragm.
1637.7.2 Design Force. Each diaphragm below the base level diaphragm shall be designed for all
tributary loads at that level using a minimum seismic force factor not less than the base shear coefficient.
1637.73 Design Force Resistance -Primary Anchors. The design force described above shall be resisted
through primary anchors from diaphragm struts provided in each diaphragm to the foundation. Primary
anchors shall be provided and designed in accordance with the requirements and limitations of Section
1637.5
1637.7A Design Force Resistance -Secondary Anchors.
1637.7A.1 General. In addition to the primary anchors required above, the design force in the downhill
direction shall be resisted through secondary anchors in the uphill foundation connected to diaphragm
struts in each diaphragm below the base level.
EXCEPTION: Secondary anchors are not required where foundations extending in the downhill
direction, spaced at not more than 30 feet on center, extend up to and are directly connected to each
