131003 jb 0131141 4
Exhibit A
FINDINGS FOR LOCAL AMENDMENTS TO
CALIFORNIA PLUMBING CODE,20l0 EDITION
Section 17958 of the California Health and Safety Code provides that the City may
make changes to the provisions in the uniform codes that are published in the California
Building Standards Code. Sections 17958.5 and 17958.7 of the Health and Safefy Code require
that for each proposed local change to those provisions in the uniform codes and published in
the California Building Standards Code which regulate buildings used for human habitation, the
City Council must make findings supporting its determination that each such local change is
reasonably necessary because of local climatic, geological, or topographical conditions.
Local building regulations having the effect of amending the uniform codes, which
were adopted by the City prior to November 23, 1970, were unaffected by the regulations of
Sections 17958, 17958.5 and 17958.7 of the Health and Safety Code. Therefore, amendments
to the uniform codes which were adopted by the City Council prior to November 23, 1970, and
have been carried through from year to year without significant change, need no required
findings. Also, amendments to provisions not regulating buildings used for human habitation,
including amendments made only for administrative consistency, do not require findings.

Key to Justification for Amendments to Title 24 of the California Code of Regulations
C This amendment is justified on the basis of a local climatic condition. The seasonal
climatic conditions during the late summer and fall create severe fire hazards to the
public health and welfare in the City. The hot, dry weather frequently results in wild
land fires on the brush covered slopes west of Interstate 280. The aforementioned
conditions combined with the geological characteristics of the hills within the City
create hazardous conditions for which departure from California Building Standards
Code is required.
G This amendment is justified on the basis of a local geological condition. The City of
Palo Alto is subject to earthquake hazard caused by its proximity to San Andreas
fault. This fault runs from Hollister, through the Santa Cruz Mountains, epicenter
of the 1989 Loma Prieta earthquake, then on up the San Francisco Peninsula, then
offshore at Daly City near Mussel Rock. This is the approximate location ofthe
epicenter ofthe 1906 San Francisco earthquake. The other fault is Hayward Fault.
This fault is about 74 mi long, situated mainly along the western base of the hills
on the east side of San Francisco Bay. Both ofthese faults are considered major
Northern California earthquake faults which may experience rupture at any time.
Thus, because the City is within a seismic area which includes these earthquake
faults, the modifications and changes cited herein are designed to better limit
property damage as a result of seismic activity and to establish criteria for repair
of damaged properties following a local emergency.
T The City of Palo Alto topography includes hillsides with narrow and winding access,
which makes timely response by fire suppression vehicles difficult. Palo Alto is
contiguous with the San Francisco Bay, resulting in a natural receptor for storm and
waste water run-off. Also the City of Palo Alto is located in an area that is potentially
susceptible to liquefaction during a major earthquake. The surface condition consists
mostly of stiff to dense sandy clay, which is highly plastic and expansive in nature. The
aforementioned conditions within the City create hazardous conditions for which
departure from California Building Standards Code is warranted.
