SECTION III
Pursuant to California Health and Safety Code § 17958.7, the City Council of the City of
Gilroy finds that each of the modifications or changes to the aforementioned Codes are
reasonably necessary because of local climatic, geological or topographical conditions.
Specifically, the City Council finds:
1. Many of the modifications or changes are reasonably necessary because of the following
climatic conditions.
(a) The region is within a climate zone that requires compliance with energy
efficiency standards for building construction. The amendment adds design flexibility
that will add to energy efficiency in construction while maintaining nationally recognized
health and safety standards. This reason is hereinafter referred to as "Climatic I."
(b) The region is within a national climate zone that is designated "Very High" on the
Termite Infestation Probability Map. This reason is hereinafter referred to as
"Climatic II."
\NVH~933.4 -5-
01-092402-04706002 Ordinance No. 2002-22
Many of the modifications or changes are reasonably necessary because of the following
geological reasons.
(a) The region is located in an area of high seismic activities as indicated by United
States Geological Survey and California Division of Mines and Geology. Recent
earthquake activities have indicated the lack of adequate design and detailing as a
contributing factor to damages that reduced the protection of the life-safety of building
occupants. This reason is hereinafter referred to as "Geological I."
(b) The region is located in an area of high seismic activities as indicated by United
States Geological Survey and California Division of Mines and Geology. Recent
earthquake activities have indicated the lack of flexibility of materials and/or building
systems has been a contributing factor to damages that reduced the protection of the life-
safety of building occupants and increased the cost of rehabilitation of structures. This
reason is hereinafter referred to as "Geological Il."
Many of the modifications or changes are reasonably necessary because of other climatic,
geological or topographical conditions, and these climatic, geological or topographical
conditions are described immediately following individual modifications or changes
adopted pursuant to this Ordinance.
A copy of these findings, together with the modification or change expressly marked and
identified to which each finding refers, shall be filed with the Califomia Building Standards
Commission.

UBC Section 1630.7 is hereby amended to read as follows:
1630.7 Horizontal Torsional Moments. Provisions shall be made for the increased shears
resulting from horizontal torsion where diaphragms are not flexible. The most severe load
combinations from each element shall be considered for design.
The torsional design moment at a given story shall be the moment resulting from eccentricities
between applied design lateral forces at levels above that story and the vertical-resisting elements
in that story plus an accidental torsion.
The accidental torsion moment shall be determined by assuming the mass is displaced as
required in Section 1630.6.
Where torsional irregularity exists, as defined in Table 16-M, the effects shall be accounted for
by increasing the accidental torsion at each level by an amplification factor, Ax, as determined by
the following formula:
2
I- 6max -I
Ax = L 1.2 6avg _1 (30-16)

(1633.2.4) Deformation compatibility. All structural framing elements and their connections, not
required by design to be part of the later-force-resisting systems, shall be designed and/or
detailed to be adequate to maintain support of design dead load plus live loads when subjected to
the expected deformations caused by seismic forces. PA effects on such elements shall be
considered. Expected deformations shall be determined as the greater of the Maximum Inelastic
Response Displacement, AM, considering PA effects determined in accordance with Section
1630.9.2 or the deformation induced by a story drift of 0.0025 times the story height. When
computing expected deformations, the stiffening effect of those elements not part of the lateral-
force-resisting system shall be neglected.
For elements not part of the lateral-force-resisting system, the forces induced by the expected
deformations may be considered as ultimate or factored forces. When computing the forces
induced by expected deformations, the restraining effect of adjoining rigid structures and
nonstructural elements shall be considered and a rational value of member and restraint stiffness
shall be used. Inelastic deformations of members and connections are permitted to occur,
provided the assumed calculated capacities are consistent with member and connection design
and detailing.

Piping installations in or under a concrete floor slab will be installed within a
chase or conduit for easy replacement, to the satisfaction of the Administrative
Authority.
REASONS FOR AMENDMENT:
1. Most of the surface soils in the Santa Clara Valley are relatively young and unconsolidated
sedimentary materials formed from a wide variety of parent materials. The varying chemical
composition, degree of weathering, and the relatively acid environment have created soils of
varying types, which are particularly corrosive in nature.
2. Much of the surface soils in the Santa Clara Valley are highly expansive (i.e., shrink - swell
behavior) and has low bearing strength. There are two types of expansive soils in the area:
a. The organic silty clays which are the recent bay muds; and
b. The plastic silty clays, which weather from the shale, found in the hills
surrounding Santa Clara Valley.
~VH~564933.4 -27-

Authority and terminate within a concrete box.
Exception: If the lateral does not exceed 50 fi. from the middle of the pubic road to the building
drain clean-out and the building drain clean-out is provided with a directional two way fitting. In
addition, the run must be substantially straight with less than an aggregate change of direction not
to exceed 135 degrees.
REASONS FOR AMENDMENT:
1. Geological II.
2. The Santa ClaraValley soils are expansive in nature. These expansive soils create unstable
conditions, which increase the potential of breaks in sewer laterals. To maintain health and
sanitary services, it is necessary to gain access, to periodically maintain public sanitary laterals.
This is accomplished by the additional clean-out as required above.
AMEND 2000 UPC 2001 CPC Section 604 as follows:
Section 604.0 Materials
604.1 Water distribution pipe, building supply water pipe and fittings shall be of brass,
copper, cast iron, galvanized malleable iron, galvanized wrought iron, galvanized steel, or
other approved materials. Asbestos-cement, CPVC, PE, PVC, or PEX water pipe
