B. An ordinance amending Chapter 15.12, Green Building Standards, of the Chula Vista Municipal
Code, adding Section 15.12.030, Cool Roof
(Chair Sanfilippo arrived at 5:25 pm)
Mr. Lou EI-Khazen, Building Official gave some background information and a brief overview of the
amendments to CVMC section 15.12.030, Cool Roof presented in the staff report. He noted the
ordinance would be presented to City Council on December 13, 2011, and then reviewed by the
California Energy Commission, which would take possibly 2-3 months. A second reading of the
ordinance would probably occur in the earlyspring.
There was discussion concerning the differentiation between Climate Zones 7 and 10 and the results
of the study. Vice Chair Sides asked for clarification on why not have the same requirements on both
climate zones. Mr. EI-Khazen explained the difference between the two climate zones and the results
of the study show cool roofs not to be cost effective in Climate Zone 7.
After further deliberation, the Board approved of adding section 15.12.030 Cool Roof to Green
Building Standards, Chapter 15.12 and recommended that Council adopt the ordinance as proposed.
MSC (LM/CS) (5-0-0-1) Recommend that City Council adopt the ordinance as proposed.
4. MEMBERS COMMENTS/CHAIRMAN'S COMMENTS/REPORTS:
There was discussion on whether they should table the election of new officers for FYE 2011/12 since

Sanfilippo asked if there were any other members that would like to be elected? There was no
response. The Committee took a vote and decided that Chair Sanfilippo and Vice Chair Sides would
remain in their current positions.

Meeting Minutes
Vice Chair Sides reminded the committee to goon line and do the two hours of Ethics Training and
also complete Form 700 if they hadn't already done so. It was important to turn in Form 700 on time
to avoid a penalty for late submission.
5. BUILDING OFFICIAL'S COMMENTSIREPORTS:
Mr. EI-Khazen stated that most likely there would not be another meeting until January 2012, unless
an appeal that is related to building codes comes up. Lou mentioned another Implementation
Measure, #4 that deals with water conservation, would be coming to the committee within 2-3
months. The measure will contain a recommendation to have builders install stub outs for gray water
from washing machines.
6. COMMUNICATIONS (PUBLIC REMARKS/ WRITTEN CORRESPONDENCE): None.

ENVIRONMENTAL REVIEW
The Director of Development Services has reviewed the proposed activity for compliance with
the California Enviromrrenhal Quality Act (CEQA) and has determined that the activity falls
within the Class 8 Catiegorical Exemption pursuant to California Code of Regulations Title 14,
Chapter 3, Article 19 (the "State CEQA Guidelines") section 15308 and therefore is exempt from
environmental review; and notwithstanding the Class 8 Categorical Exemption, the Director of
Development Services has further determined that there is also no possibility that the activity
may have a significant effect on the environment; therefore, pursuant to section 15061(b)(3) of
the State CEQA Guidelines the activity is exempt from the provisions of CEQA. Thus, no
environmental review is required.

llISCUSSION
On May 3, 2011, City Council approved Resolution 2011-076 adopting the proposed Climate
Adaptation Plans for the 11 Climate Adaptation Strategies. Strategy # 4, Local Water Supply
and Reuse, proposed adopting new regulations to incorporate. clothes a?~~kler graywater plumbing
shib-out in new residential development to facilitate Ihe`'Iater instaipalaon of a graywater
irrigation system. G~raywater is water fiom waslmlg machines, showers, liafhttlbs, and bathroom
sinks. It is water that contains some soap but is clean enough to water plants. As proposed, the
ordinance only applies to detached single-family dwellings and duplexes. `Staff took into
consideration other residential building types such as, attached single-family (to~vnhomes) and
multi-family and because of the typical small lot srze` 4l' attacfied single-family units and
impracticality for multi-family buildings, staff is recomtrending excluding theses types of
residential units fiom the requirements.
By 2050, San Diego County's demand for water is expected to increase by 37% as a result of
population and economic growth. In addition, prolonged droughts exacerbated by climate
change could reduce water supplies from imported sources'by 20% or more. These climate
change impacts could ~rmtt tmp~rt~d water availability, increase utility costs for residents and
businesses, and lead tz~hgher demand for local water sources. Using laundry water for irrigation
is one of many ways to::conserve potable water supply and reduce flows to ow wastewater
system. A clothes washer graywater system can-save a typical single-family dwelling up to
7,000 gallop o£ eatable wet€rper year Pleasing laundry water for irrigation conserves our
precious water resources, conserve`s energy needed to pump and treat water, and saves money on
the water
bill.
The current California Plumbing Code (CPC), Chapter 16A, Part I, allows a residential clothes
washer graywater irrigation system to be installed without a construction permit if the system is
installed and operated in accordance with the requirements of Section 1603A.L1 of the CPC. A
copy of Section 16Q3A.1.1 of the CPC is provided for reference as Attachment X. The main
requirements of the C~'C are 1) the user shall be able to direct the flow of the graywater to the
irrigation or the buildlmg sewer, 2) the graywater shall be contained on site within the irrigation
field, 3) ponding or runoff is prohibited, 4) water used to wash diapers or similarly soiled or
infectious garments, or water containing hazardous chemicals shall be diverted to the building
sewer, and 5) an operation and maintenance manual shall be provided to the building occupant
and to remain with the building throughout the life of the system. Staff will assist builders with
the development of the information that needs to be included in the homeowner's manual.

- Staff is proposing two approaches to installing the pre-plumbing and stub-out. One involves a
separate clothes washer graywater standpipe, similar to the standard clothes washer sewer
standpipe, where the homeowner can manually move the washer discharge pipe between the two
outlet boxes. The other involves a 3-way diverter valve where the valve can be positioned to
direct the graywater to either the sewer standpipe or irrigation stub-out. The proposed
installation requirements are outlined in the City of Chula Vista Clothes Washer Crraywater Pre-
Plumbing and Stub-Out for New Residential Construction (Exhibit A to the proposed
Resolution). Realizing that there might be other acceptable code complying approaches, the
proposed Ordinance and installation requirements give the Building Official the ability to
approve equivalent alternate methods and/or materials. Furthermore, realizing that some
properties and building layouts may not be suitable for a graywater system, the proposed
ordinance gives the Building Official the ability to modrfy or-v~arve theaognirements when it can
be demonstrated to his satisfaction that compliance with the,requirementa=is impractical due to
construction or physical constraints, or due to site and/or soil conditions.
Homeowners must ensure that when they later install a graywater irrigation system on their
property that it is designed and installed safely, is consistent vvith applicable code requirements,
and is operated in a manner that causes no harm or damage Ya themselves or neighbors. To assist
homeowners who are interested in utilizii~ clothes washer g`r~y water systems, staff will develop
a "best practices" manual describing propel' ihstallation methods for installing the systems. The
manual will address clothes washer gray water systems at both new homes (to complement the
new stub-out requirement described above) and at existing residences. Special emphasis in the
guides will also be placed on maximizing the system's effeeti eness, protecting human health,
and avoiding water runoff.
The installation of a stub-out at rime of new const~xcti~n facilitates the later installation and use
of a graywater system iri residences, Based on staft°sixesearch, the incremental cost fox installing
the pre-plumbing and stub-out duffing new construction is estimated to be between $200 and
$350 depending on the location of the laundry room in the house in relation to the most useful
location ~o>• the exterior stub-out.
In addition to presenting the proposed Ordinance and Resolution to the Board of Appeals and
Advisors (BOA&A) and the"resources Conservation Commission (RCC), on September 19,
2012, staff presented them to the Development Services Oversight Committee (DSOC). The
DSOC consists bf tepresentatives from the design and construction industries and engaged
- members of the generdl public Committee members raised some issues that were addressed by
staff and did not express any opposition to what is being proposed.
Expiration of Local Standards
Pursuant to State law, local amendments to California building codes will no longer be in effect
the date new California building codes take effect. Therefore, if adopted, the proposed local
standards will have to expire upon the date the 2010 California Plumbing Code is no longer in
effect; currently projected to expire January 1, 2014 when the 2013 State codes take effect. If
City Council adopts the proposed Ordinance and Resolution, staff will reintroduce the locally

adopted standards for City Council's consideration and adoption at the time staff brings forward
the new building codes to Council for adoption.
DECISION MAKER CONFLICT
Staff has determined that the recommendations requiring Council action are not site specific and
consequently the 500 foot rule found in California Code of Regulations Section 18704.2(x)(1) is
not applicable to this decision. Staff is not independently aware, nor has staff been informed by
any City Councilmember, of any other fact that may constitute a basis for a decision maker
conflict of interest in this matter.
CURRENT YEAR FISCAL IMPACT
No current fiscal year impact. Plan review and inspection cash wrll be mhumal and staff is not
proposing an increase in fees. The cost of public education and outreach offorts will be covered
under the ctu-rent Conservation and Environmental Services' budget.
ONGOING FISCAL IMPACT
Plan review and inspection costs will be minimal and staff is not proposing an increase in fees.
Ongoing cost of public education and outreach efforts will be covered under the Conservation and
Environmental Services' budget.

WHEREAS, a clothes washer graywater system can save a typical single-family dwelling
up to 7,000 gallons of potable wafer per year, and
WHEREAS, fhe installation bf astub-out at time of construction greatly facilitates the
use of graywater in residences; and
WI-IET2EAS, the City Gouneil specifically and expressly finds and declares that adding
section 15.28.020 to Chapter 13.28 is necessary due to local climatic conditions. As a result of
prolonged droughts exacerbated by climate change, it is anticipated that water supplies from
imported sources are reduced, and furthermore, as a result of population and economic growth,
demand for water is erected to increase. These impacts could limit imported water availability,
lead to higher demand'for local water sources and increase utility costs. Requiring single-source
graywater stub-out in new residential development facilitates the use of graywater for irrigation
which in turn helps address These water-related climate change impacts.

Clothes Washer Graywater Pre-Plumbing and
~~w or Stub-Out for New Residential Construction
CHULA VISTA
These requirements, or an equivalent alternate method and/or material
approved by the Building Official, are applicable in all new detached single
family dwellings and duplexes.
There are two basic approaches to installing the pre-plumbing and stub-out for a future clothes
washer graywater system in newly constructed dwelling units. Both methods are installed
adjacent to the regular clothes washer standpipe to allow the clothes washer to drain into the
regular sewer standpipe (leading to the building sewer) or be diverted to a graywater stub-out on
the exterior of the building. The following are the twp`xriethods:
Configuration #1 involves a separate graywater standpipe installed adjacent to the regular
clothes washer standpipe. This can be done by instal`1%ng an.additonal outlet box dedicated for
the graywater standpipe. The following installation requrrements apply:
• The standpipe shall be vented (an:air admittance valve is acceptable) and trapped, and all
plumbing materials shall be 2-inch'in s{ze.
The standpipe shall have a 2-inch overflow pipe leading dov~nward to the regular washer
sewer standpipe.
• The graywater standpipe outlet box shall be as close as possible to the sewer standpipe so
that the flexible washing ;machine wastewater disch~tge pipe can be manually moved
between the two outlet l~o~,drainage pipes to either flow into the sewer or to a future
graywater systehl'attached tci the stub-out.
• The plumbing systett~ must-have a minimtari %a" per foot slope towards the exterior stub-
out.
Configuration #2 uses a 3-Way Diverter Valve connected to the end of the flexible washing
machine wastewater discharge pipe: The valve position directs the graywater to either the
regular stand~Zipe leading to the sewer or to the graywater sub-out. The following installation
requirements'~~ply:
• The diverter valve and_all additional plumbing materials shall be minimum 1-inch in size
or greater. '
• The graywater istub-out shall have a vacuum breaker installed at the highest point in the
connection, either inside or outside.
• The diverter valve must be accessible and securely fastened to the interior wall at the
clothes washer.
The following general requirements apply to both configurations:
• Permanent labeling.
o Regular standpipe leading to the building sewer and diverter valve in position to
feed into the sewer standpipe must be permanently labeled "Blrilding Sewer."
Page 1 of 2
EXHIBIT A
o Standpipe dedicated to feed the graywater stub-out and diverter valve in the _
position to feed the graywater stub-out must be permanently labeled "Graywater
to Landscape."
o Exterior graywater stub-outs must be permanently labeled "Graywater Stub-Out: -
Caution-Unsafe Water."
o Sections of the graywater piping 5-feet or longer must be labeled "CAUTION:
NON-POTABLE WATER, DO NOT DRINK."
_ • An operation and maintenance manual shall be provided. Directions shall indicate the
manual is to remain with the building throughout the life of thq system and indicate that
upon change of ownership or occupancy, the new owner or "ienaht: shall be notified the
structure contains a graywater stub-out or system.
• Stub-out
o Must extend a minimtun of 3-inches outward past the exterior wall.
o Must have a rubber cap with a stainless steel tightening ,ciiaw band to keep it
closed when not conducting graywater, '
o Exterior stab-outs should measure:. between 18-inches and 4$ incktes above
finished exterior grade. The higher tie better to s~sist with the gravit3~ flow of the
system but not to exceed 48" above finished exterior grade.
o The stub-out should be as close to the largest area of landscaping as possible.
• All exterior materials shall be pt4tected from UV rays by a latex paint, except for the
vacuum breaker device.
• All work and materials used shall Canfbr'tti Ya the Califorris Phunbing Code in effect at
the time of installation.
• Both ends of the graywater stub-out pliaxnbing need to be"identified on the plans.
• The graywater plumbing;and stub-out is required wherever the clothes washer outlet box
is installed in the building.
