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 means 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.
Exception: The provisions of this section do not apply to:
V
l . One-story, light -frame buildings classified as R-3 and U occupancies and not
exceeding 1,000 square feet in area or 12 feet in height.

such work within any 12 month period does not exceed 50 percent of the value of
the existing building.
3. Swimming pools, retaining walls, fences and minor work of a similar nature.
7. Special Studies Zones. Work within the special studies zones established under Sections 2622
and 2623 of the California Public Resources Code shall comply with State laws, policies, criteria,
rules and regulations applicable to such work. Fees established by Chapter 7.5 of Division 2 of the
California Public Resources Code shall be collected and disbursed as required by State law. In
addition to the State regulations, the provisions of this section shall apply when geologic
investigations, mapping, aerial photographs, other acceptable data or Special Studies Zones Maps
show the location of a known active earthquake fault as described in this section.

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
23
downhill and approximately perpendicular to the uphill foundation.
HILLSIDE BUILDING is any building or portion thereof constructed on or into a slope steeper
than one unit vertical in three units horizontal (33.3%). 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 1613.8.5 and 1613.8.7.3 between the diaphragm and the uphill foundation.
SECONDARY ANCHORS are diaphragm anchors designed for and providing a redundant
diaphragm to foundation connection, as described in Sections 1613.8.6 and 1613.8.7.4.
UPHILL DIAPHRAGM EDGE is the edge of the diaphragm adjacent and closest to the highest
