Exhibit A
FINDINGS FOR LOCAL AMENDMENTS TO CALIFORNIA PLUMBING CODE,
TITLE 24, PART 5
Section 17958 of the California Health and Safety Code provides that the City may make changes
to the provisions of the California Building Standards Code. Sections 17958.5 and 17958.7 of the
Health and Safety Code require that for each proposed local change to those provisions of 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 do not require
findings.

Key to Justification for Amendments to Title 24 of the California Code of Regulations
A This is an administrative amendment to clarify and establish civil and administrative
procedures, regulations, or rules to enforce and administer the activities by the Palo Alto Building
Inspection Department. These administrative amendments do not need to meet HSC
18941.5/17958/13869 per HSC 18909(c).
C This amendment is justified based on 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 based on 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 of the epicenter of the 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 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 and emergency response vehicles difficult. Palo Alto
is contiguous with the San Francisco Bay, resulting in a natural receptor for storm and wastewater
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.
