or 2306.2.1(2). For structures assigned to Seismic Design Category D. E or F the allowable shear
capacities shall be set forth in Table 2306.2.1(3) or 2306 2 1(4) The allowable shear capacities in
Table 2306:2.1(1) or-2306.2.1(2) are permitted to be increased 40 percent for wind design.
Wood structural panel diaphragms fastened with staples shall not used to resist seismic
forces in structures assigned to Seismic Design CategoryD E orf
Exception: Staples may be used for wood structural panel diaphragms when the allowable shear
values are substantiated by cyclic testing and approved by the building official

DIAPHRAGM ANCHORS. Assemblies that connect a diaphragm to the adjacent foundation at the
uphill diaphragm edge.
DOWNHILL DIRECTION. The descending direction of the slope approximately perpendicular to the
slope contours.
FOUNDATION. Concrete or masonry which supports a building, including footings, stem walls,
retaining walls, and grade beams.
FOUNDATION EXTENDING IN THE DOWNHILL DIRECTION. A foundation running downhill and
approximately perpendicular to the uphill foundation.
HILLSIDE BUILDING. 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 supportedon or into the
slope, these regulations apply to the entire building.
PRIMARY ANCHORS. Diaphragm anchors designed for and providing a direct connection as
described in Sections 1613.12.5 and 1613.12.7.3 between the diaphragm and the uphill foundation
SECONDARY ANCHORS. Diaphragm anchors designed for and providing a redundant diaphragm to
foundation connection, as described in Sections 1613.12.6 and 1613.12.7.4.

excavation and earthwork construction, including fills and embankments, in floodways within flood
hazard areas established in Section 1612.3 or in flood hazard areas where design flood elevations

hydrologic and hydraulic analyses performed in accordance with standard engineering practice
that the proposed work will not result in any increase in the level of the base flood.
J101.3 Hazards. Whenever the building official determines that any land or any existing
excavation or fill has, from any cause, become a menace to life or limb or endangers public or
private property, or adversely affects the safety, use or stability of public or private property, the
owner or other person in legal control of the property concerned shall upon receipt of a written
notice thereof from the building official, correct such condition in accordance with the provisions of

land sufficiently close to the property line to endanger any adjoining public street sidewalk alley,
or other public or private property without supporting and protecting such property from settling
cracking or other damage that might result. Special precautions approved by the building official
shall be made to prevent imported or exported materials from being deposited on the adjacent
Public way and/or drainage courses.

A. Climatic Conditions. Adverse climatic conditions and
strong winds such as those in existence in the City of Vernon increase
the likelihood of fire spreading (conflagration) from one building to
another.

B. Geological Conditions. Geological conditions in the
City of Vernon are affected by the nearby location of earthquake faults
that can create tremendous loss of life and structures in the City.
C. Topographical Conditions. Topographical conditions of
the City of Vernon coupled with the density of buildings, limited
setbacks, narrow access to buildings and narrow streets potentially
create a problem for governmental agencies to respond to emergency
conditions.
SECTION 2: Amendments to the 2010 Editions of the
California Building, Electrical,.Mechanical, Plumbing, Existing
Building, Residential, Green Building Standards, and Energy Codes, and
the 2006 ICC Electrical Code Administrative Provisions and the 2009
