Exhibit A
FINDINGS FOR LOCAL AMENDMENTS TO
CALIFORNIA GREEN BUILDING STANDARD 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, geologicat 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 ofthe hills within the City create
hazardous conditions for which departure from California Building Standards 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 ofthe 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 Green building 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 green provisions in this Chapter are designed to
achieve the following goals:
(a) Increase energy efficiency in buildings;
(b) Increase water and resource conservation;
----,{CTReauce waste generated by construction and demolition projects;
(d) Provide durable buildings that are efficient and economical to own and operate;
(e) Promote the health and productivity of residents, workers, and visitors to the city;
(f) Recognize and conserve the energy embodied in existing buildings;
(g) Encourage alternative transportation; and
(h) 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 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 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 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.
