AN
ORDINANCE ADDING SECTIONS 15.20.O8O TO Article II OF
CHAPTER15.20 OF TITLE 15 OF THE ALAMEDA COUNTY GENERAL
ORDINANCE CODE REGULATING NEW CONSTRUCTION PROJECTS IN
THE UNINCORPORATED AREA OF THE COUNTY FOR the PURPOSE OF
INSTALLING EXCESS FLOW GAS SHUTOFF DEVICES.
The
Board of Supervisors or the County of Alameda ordains as
follows:
SECTION
1
Pursuant
to California Health and Safety Code Sections 17958.5 and
17958.7 the Board of Supervisors of Alameda County hereby
finds that it is reasonably necessary to modify the
requirements of the California Building Standards Code
due to local climatic, geographical, or topographical
conditions. It is generally accepted that Alameda County
will experience moderate and severe earthquakes in the
foreseeable future. These earthquakes will pose a serious
threat to life and property. In order to mitigate the
potential hazard of fire resulting from gas piping
damaged by seismic movement, the installation of Excess
Flow Devices (non-motion sensitive) shall be required in
all new construction and in certain remodeling in
accordance with Alameda County ordinance. The full text
of the express legislative findings of the County of
Alameda in support of requiring the installation of
Excess Flow Devices is on file and available for review
in the office of the Building Official for the County of
Alameda and with the California Building Standards
Commission.
Based
on the foregoing, the Board of Supervisors of the County
of Alameda hereby ordain that Article II of Chapter
15.20, Title 15 of the General Ordinance Code of the
County of Alameda shall be amended by adding Section
15.20.080 as Follows:
