Exhibit A
FINDINGS FOR LOCAL AMENDMENTS
TO CALIFORNIA PLUMBING CODE
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
-.. -.m--------sections1795S~1795s-:5and~li<}51t7oftheHealthlllR.tSafet)tCode. Therefore.,arnendments-ro-.. -.-~~
tne uniform codes which were adoptedJ2Y the City Council prior to November 23, 127....:::0-,-, -=:an=d ____ _
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 findings.
The findings made by the Council of the City of Palo Alto in Ordinance 3215
adopting the 1979 Uniform Plumbing Code reaffirmed the fmdings 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.
16.08.070 Section 305.4 added -Sewers Required (Palo Alto Sewer Use Ordinance
referenced)
Finding: This section is amended to conform to other provisions of the Palo Alto Municipal
Code.andis specifically authorized in Section305.3 of the California Plumbing Code.
16.08.080 Table 6-4 (Footnote 1) amended; 16.04.090 Section 604.11 PEX, and Sub-
Sections 604.11.1 PEX Fittings, and 604.11.2 Water Heater Connections adopted.
Finding: These amendments allow the use ofPEX, but not PE-AL-PE or PEX-AL-PEX, piping
in potable water supply and distribution systems within buildings. PEX is a recognized material
that is a bona-fide alternative to copper and other metallic water piping. 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 influent to the Plant in accordance with the City's
approved Copper Action Plan and NPDES (Discharge) Permit under which the Plant operates.

Materials; 16.04.180 Section 1101.3 amended -Storm Drainage, General (Material Uses);
and 16.04.200 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. 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.
16.08.130 Section 710.1 amended -Drainage of Fixtures Located Below the Next
Upstream Manhole or Below the Main Sewer Level; 16.04.140 Section 714.4 amended -
Damage to Public Sewer or Private Sewage System (Commercial Food Waste Grinders

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 sewer 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 are intended to comply 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.
16.08.160 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.-1-90 Section 1101.9 amended -Filling Stations and Motor Vehide· 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 sewer 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.
