Exhibit A
FINDINGS FOR LOCAL AMENDMENTS TO
CALIFORNIA ENERGY CODE, 2013 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 Safety 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 ofthe 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 Energy Code is required.
Failure to address and significantly reduce greenhouse gas (GHG) emissions could result in
rises in sea level, including in San Francisco Bay, that could put at risk Palo Alto homes and
businesses, public facilities, and Highway 101 (Bayshore Freeway), particularly the mapped
Flood Hazard areas of the City. Energy efficiency is a key component in reducing GHG
emissions, and construction of more energy efficient buildings can help Palo Alto reduce its
, share of the GHG emissions that contribute to climate change. The burning of fossil fuels
used in the generation of electric power and heating of buildings contributes to climate
change, which could result in rises in sea level, including in San Francisco Bay, that could put
at risk Palo Alto homes and businesses 1 public facilities, and Highway 101. Due to decrease
in annual rain fall, Palo Alto experiences the effect of drought and water saving more than
some other communities in California.
E Energy efficiency enhances the public health and welfare by promoting the environmental
and economic health of the City through the design, construction, maintenance, operation
and deconstruction of buildings and sites by incorporating green practices into all
development. The provisions in this Chapter are designed to achieve the following goals:
(a) Increase energy efficiency in buildings;
(b) Increase resource conservation;
(c) Provide durable buildings that are efficient and economical to own and operate;
(d) Promote the health and productivity of residents, workers, and visitors to the city;
(e) Recognize and conserve the energy embodied in existing buildings; and
(f) Reduce disturbance of natural ecosystems.
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 Lorna
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 of
these 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
9
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 Codes is
warranted.
