recognized as being vulnerable to sustaining significant damage during moderate to strong
earthquakes; and
WHEREAS, pursuant to the "Unreinforced Masonry Law," California Government Code
sections 8875 et seq. the City implemented a seismic hazard program that identified unreinforced
masonry buildings that may be hazardous to their occupants, pedestrians and adjacent structures
and their occupants in the event of an earthquake; and
WHEREAS, the City contains approximately 35 buildings of unreinforced masonry
construction that have been determined to be "potentially hazardous" during a seismic event and
that have not been adequately strengthened; and
WHEREAS, in 2004, the City Council authorized the expenditure of $100,000 for
engineering studies to assist the owners of unreinforced masonry buildings to identify the
potential hazards of their buildings and provide standards for both analyzing and retrofitting
potentially hazardous unreinforced masonry buildings; and
WHEREAS, 14 of the 35 unreinforced masonry building owners participated in the
engineering studies; and
WHEREAS, it is the desire and intent of the City Council to provide Gilroy citizens with

Sec. 6.53 Codes Adopted
The CCBC Appendix Chapter 1, a copy of which is on file in the office of the city clerk
of the city, is hereby adopted and made a part of this Article as though fully set forth herein, and
as supported by the following findings, based on local climatic, geological or topographical
conditions, which are fully set forth below:
Geological I. The City of Gilroy is located in an area of high seismic activities as
indicated by the United State Geological Survey and California Division of Mines and Geology.
During moderate to strong seismic events, URM buildings that have not been retrofitted have
been widely recognized to be the most dangerous buildings in CA and pose the greatest life
safety hazard due to their potential to partially or totally collapse in a seismic event. This finding
is hereinafter referred to as "Geological I."
Geological II. The City of Gilroy is located in an area of high seismic activities as
indicated by the United State Geological Survey and California Division of Mines and Geology.
Recent earthquake activities have indicated that URM buildings have inadequate connections
and roof and floor diaphragms to withstand moderate to strong earthquake loads. Consequently.
URM buildings pose the greatest life safety hazard to building occupants and pedestrians
adjacent to these buildings during a seismic event. This finding is hereinafter referred to as
"Geological II."
The CCBC as herein adopted and further supported by the above - mentioned findings is
subject to the following modifications:
(a) Scope
Section A102 — Scope is amended to read as follows:
"A102.1 General. The provisions of this Article shall apply to all existing buildings covered
under the city mandatory seismic retrofit program having at least one unreinforced masonry wall
as defined in this Article. The elements regulated by this Article shall be determined in
accordance with Table A -1 -A. Except as provided herein, other structural provisions of the CBC
shall apply.
A102.2 - Essential and Hazardous Facilities. Buildings or structures in Occupancy
Categories 1 and 2 of Table 16 -K, and covered under the c mandatory seismic retrofit program of
the CBC, shall be strengthened in accordance with the provisions of this Article or requirements
of the UBC for new buildings, whichever is more restrictive."
(b) Definitions
The definition of an unreinforced masonry- in Section A103 is amended to read as follows:
"UNREINFORCED MASONRY (URM) WALL means any unreinforced masonry wall
supporting its own weight when over six (6) feet in height or any masonry wall that has all of the
following characteristics:
IJH1693711.9 -13-
01 -092006 - 04706083
Ordinance No. 2006 -19
1. Provides the vertical support for a floor or roof.
2. Hasa total superimposed load of over 100 pounds per linear foot.
3. Has an area of reinforcing steel less than 50 percent by empirical methods or less than 25
percent by analysis of that required by the CBC."
(c) Symbols and Notations
New symbols are added to Section A104 — Symbols and Notations as follows: "Fp = Design
Seismic Forces on a part of the structure, based on working stress design methods. I =
Importance Factor in accordance with Table A -1 -H."
(d) Minimum Design Lateral Forces
Section A110.1 Minimum Design Lateral Forces is amended to read as follows:
"Buildings shall be analyzed to resist minimum lateral forces assumed to act non - concurrently in
the direction of each of the main axes of the structure in accordance with the following:
V =.20 W (A10 -1 -1)
for essential facilities; or
V =.166 W (A10 -1 -2)
for buildings that are not essential facilities, but have an occupant load greater than 100; or
V =.133 W (A10 -1 -3)
for all other buildings.
Exception: For qualified historical buildings, alternative criteria may be approved when
implementation of the provisions of this section conflicts with the objectives of preserving the
historical features of the building.
For buildings more than one story in height, the total force shall be distributed over the
height of the building in accordance with the procedures of Chapter 16 of the CBC .

Exception: 1. Unreinforced masonry walls for which height -to- thickness ratios do not
exceed ratios set forth in Table A -1 -B need not be analyzed for out -of -plane loading.
Unreinforced masonry walls which exceed the allowable h/t ratios of Table A -1 -B shall be
braced according to Section A113.5. 2. Parapets complying with Section Al 13.6 need not be
analyzed for out -of -plane loading."

Cp of 0.12 applied to the Wp unless a greater force results from the distribution of lateral
forces in accordance with Chapter 16 of the Building Code.
3 For determination of the capacity of the shear connections at the edges of wood diaphragms,
the value of Cp shall be 0.2. However, the strength of the shear connections need not exceed
