EXHIBIT" A"
FINDINGS FOR LOCAL AMENDMENTS TO
CALIFORNIA PLUMBING CODE, 2010 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 oflocal 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 fmdings. Also,
amendments to provisions not regulating buildings used for human habitation, including
amendments made only for administrative consistency, do not require fmdings.
The findings made by the Council of the City of Palo Alto in Ordinance 3215 adopting the 1979
Uniform Plumbing Code reaffirmed the findings which had been made by prior Council actions
in adopting amendments to the Uniform Plumbing Code subsequent to November 23, 1970.
Such findings have been reaffirmed with each successive adoption of the Uniform Plumbing
Code (California Plumbing Code) as published in the California Building Standards Code, and
are hereby reaffirmed and expressly made applicable to all local amendments that are hereby
again adopted and carried through without significant change.
16.08.60 Section 305.4 added -(Palo Alto Sewer Use Ordinance referenced).
Finding: This section is amended to conform to other provisions of the Palo Alto Municipal
Code and is specifically authorized in Section 305.3 of the California Plumbing Code.
16.08.080 -Section 701.1.4 amended -Materials; 16.08.090-Table 7-1 amended; 16.08.150-
Section 1101.3 amended -Material Uses; 16.08.170-Section 1105.1.2 amended -Roof
Drains (Materials).
Finding: These amendments prohibit the use of lead, copper and brass piping in sanitary
drainage systems within buildings, except in limited circumstances or when specifically
approved by the Building Official. The City's Regional Water Quality Control Plant has, for
many years, implemented programs to reduce copper and other heavy metal discharges into San
Francisco Bay to comply with State Regional Water Quality Control Board requirements. These
amendments are consistent with and support the City's efforts to reduce the amount of copper
and heavy metal influent to the Plant in accordance with the City's approved Copper Action Plan
and NPDES (Discharge) Permit under which the Plant operates.
101026 sh 8261461 6
16.08.100 Section 710.1 amended -Drainage of Fixtures Located Below the Next
Upstream Manhole or Below the Main Sewer Level; 16.08.110 Section 714.4 amended -
Commercial Food Waste Grinders Prohibited; 16.08.120 Section 719.7 added -Cleanouts;
16.08.140 Section 1014.1.3 amended -Food Waste Disposal Units and Dishwashers.
Finding: These amendments are required by the location of the City of Palo Alto between the
Santa Cruz Mountain foothills and the San Francisco Bay, and the presence of several substantial
creeks flowing through highly developed residential, urban and industrial areas. The City
operates its own sanitary sewage collection system and Regional Water Quality Control Plant
and is subject to State and Federal laws regarding both point and non-point source discharges.
These amendments promote compliance with State Water Resources Control Board requirements
to minimize sanitary sewer overflows caused by blockages in the sewer system and protect the
various creeks, the San Francisco Bay and Palo Alto residents from unnecessary sewage spills
and threats to public health. .
16.08.130 Section 808.0 amended -Single Pass Cooling Water Systems Prohibited.
Finding: This amendment promotes water conservation by prohibiting potable water from being
used solely for the purpose of cooling appliances and other mechanical systems. This
amendment is necessitated by local climatic conditions rendering potable water as a scarce and
valuable resource. '
16.08.160 Section 1101.9 amended -Motor Vehicle Washing Establishments.
Finding: This amendment prohibits the paved areas of public filling stations from draining
towards sumps and gratings that could otherwise be connected to the sanitary sewage collection
system, which in addition to polluting the sanitary sewer, could cause explosions or other
. hazardous events. The amendment is consistent with Best Management Practices contained
within the City's Storm Water Pollution Prevention Plan as well as statewide best practice
guidelines for the proper design of motor vehicle fueling stations.
