SUMMARY
At City Council's direction, the Climate Change Working Group developed strategies through a 12-
month public process to reduce future risks and costs from expected local climate change impacts
(known as climate "adaptation"). Staff has since developed more detailed implementation plans for
these CZimate Adaptation Strategies which outline specific steps, costs, and timelines. If approved,
staff will partially implement the strategies based on available funding and return to City Council
with specific policies and ordinances for future consideration.
ENVIRONMENTAL REVIEW
The Development Services Director has reviewed the proposed activity for compliance with the
California Environmental Quality Act (CEQA) and has determined that the action qualifies for a
Class 8 categorical exemption pursuant to Section 15308 [Actions by Regulatory Agencies for
Protection of the Environment] of the State CEQA Guidelines because, the contemplated action
proposes adoption of climate protection polices and programs designed to reduce harmful
greenhouse gas or "carbon" emissions and their associated impacts. Thus, no further
environmental review is necessary.
RECOMMENDATION
Council adopt the resolution.

BOARDS/COMMISSION RECOMMENDATION
The Climate Adaptation Strategies' Implementation Plans were presented to the Resource
Conservation Commission, the Planning Commission, and the Board of Appeals & Advisors to
solicit feedback on their content and structure in February/March 2011. The Resource
Conservation Commission and the Planning Commission formally recommended that City
Council adopt the plans, while the Board of Appeals & Advisors just provided comments on the
plans to staff due to the lack of a quorum at their meeting. Similarly, the Chula Vista
Redevelopment Corporation was provided a copy of the plans for review and encouraged to
provide comments to staff.
DISCUSSION
The City of Chula Vista has long understood the threats of climate change to its community and
has established itself as a leader amongst municipalities in planning to reduce or "mitigate"
citywide greenhouse gas emissions. However, despite efforts both locally and globally to
mitigate emissions, some level of climate change will still occur and have noticeable impacts on
the San Diego region. Expected impacts include hotter and drier weather, diminished imported
water supplies, more poor air quality/heat wave days, more frequent wildfires, shifts in habitat
and species distribution, and increased rates of sea level rise.
In October 2009, the City Council directed the Chula Vista Climate Change Working Group
(CCWG) -comprised of businesses, residents, and community representatives - to identify
Chula Vista's vulnerability to expected local climate change impacts and to develop strategies to
reduce future risks and costs from these impacts (known as climate "adaptation"). Through 13
public meetings and forums over a 12-month period, the CCWG ultimately chose 11 strategies
related to energy and water supplies, public health, wildfires, biodiversity, coastal resources, and
the local economy:
Strategy #1- Cool Paving
Strategy #2 - Shade Trees
Strategy #3 - Cool Roofs
Strategy #4 - Local Water Supply & Reuse
Strategy #5 - Storm Water Prevention & Reuse
Strategy #6 - Education & Wildfires
Strategy #7 - Extreme Heat Plans
Strategy #8 - Open Space Management
Strategy #9 - Wetlands Preservation
Strategy #10 -Sea Level Rise & Land Development Codes
Strategy #11 -Green Economy
In October 2010, the City Council accepted the CCWG's recommendations and directed City
staff to develop implementation plans within 180 days. Pursuant to that direction, the Climate
Adaptation Strategies' Implementation Plans (Attachment A) were developed by a multi-
department team and provide a more detailed framework for each strategy's implementation
components, timelines, and costs. The plans were designed to ensure that they complement
(without being redundant) Chula Vista's current climate "mitigation" measures to reduce
greenhouse gas emissions and to be flexible enough for future modifications as new climate
change impacts data and modeling becomes available. They were also structured to build upon
9-2
existing municipal efforts (rather than create new stand-alone initiatives or programs) to improve
their implementation feasibility considering the City's current staffing and funding limitations.
Many of these existing efforts are supported through external grants and partnerships which can
only be used for environmentally-related activities and programs. Finally, staff integrated the
feedback from various City Commissions and other stakeholders in finalizing the plans
(Attachment B).
The proposed Climate Adaptation Strategies will help to reduce the City's future risks and costs
from expected local climate change impacts. If the Climate Adaptation Strategies'
Implementation Plans are approved by Council, staff will proceed with partially implementing
the plans based on available funding and will develop the specific policy/ordinance language
which would then be presented to the various City Commissions and, ultimately, the City
Council for future review and consideration. Staff will also pursue additional external funding
sources to support full, long-term implementation.
DECISION MAKER CONFLICT
Staff has reviewed the decisions contemplated by this action and has determined that, in each
case, either: (i) the decision is not site specific and consequently the 500 foot rule found in
California Code of Regulations section 18704.2(a)(1) is not applicable to this decision; or (ii)
staff has reviewed the property holdings of the City Council and has found no property holdings
within 500 feet of the boundaries of the property which is the subject of the action (i.e., Strategy
No. 8 -the Otay Ranch Preserve boundary, and Strategy No. 9 -the Chula Vista Bayfront Master
Plan and the Otay Valley River Park boundaries).
CURRENT YEAR FISCAL IMPACT
Initial implementation of all 11 strategies will be phased and will cost approximately $554,000.
Of these initial costs, existing funding sources will allow at least 8 of 11 strategies to be fully or
partially implemented. Because staff will only implement the measures based on available
funding, approval of the Climate Adaptation Strategies' Implementation Plans will not create a
new impact to the General Fund.
ONGOING FISCAL IMPACT
Ongoing implementation of the 11 strategies will cost approximately $337,000 annually and will
be partially covered through existing funding sources as well. Because staff will only implement
the measures based on available funding, approval of the Climate Adaptation Strategies'
Implementation Plans will not create a new, ongoing impact to the General Fund. In some cases,
the Climate Adaptation Strategies may generate utility cost savings for municipal operations
(and the community) over time. Furthermore, the cost of "no action" could be significant in the
long term through public and private infrastructure damages, public safety and health issues, and
energy and water shortages.

SUMMARY
The City of Chula Vista has long understood the threats of climate change to its community and
has established itself as a leader amongst municipalities in planning to reduce or "mitigate"
citywide greenhouse gas emissions. However, despite efforts both locally and globally to
mitigate emissions, some level of climate change will still occur and have noticeable impacts on
the San Diego region. In order to manage these likely climate change impacts and to reduce
future risks and costs, the City of Chula Vista's Climate Change Working Group -comprised of
residents, businesses, and community representatives -recommended 11 strategies to "adapt" the
community to these impacts within energy and water supply, public health, wildfires, ecosystem
management, coastal infrastructure, and the local economy sectors.

At City Council's direction, staff has developed more detailed implementation plans for these
Climate Adaptation Strategies. For each strategy, the plans outline specific implementation
components, critical steps, costs, and timelines. In order to limit the necessary staffing and
funding required to implement the strategies, the plans were also designed to build upon existing
municipal efforts rather than create new, stand-alone policies or programs. Initial
implementation of all 11 strategies will be phased in over the next 3 years and will cost
approximately $554,000. Of these initial costs, existing funding sources will allow at least 8 of
11 strategies to be fully or partially implemented. Ongoing implementation of the 11 strategies
will cost approximately $337,000 annually and will be partially covered through existing funding
sources as well. If the Climate Adaptation Strategies' plans are approved by City Council, staff
will partially implement the measures based on available funding and pursue additional external
funding sources to support full, long-term implementation. Therefore, approval of the Climate
Adaptation Strategies will not create a new impact to the General Fund.

OVERVIEW
Since the early 1990s, Chula Vista has been engaged in multiple climate change forums
including the United Nations Framework Convention on Climate Change, the ICLEI Cities for
Climate Protection campaign, the California Climate Action Registry, and the U.S. Conference
of Mayor's Climate Protection Agreement and has committed to reduce its greenhouse gas
(GHG) emissions 20% below 1990 levels. To accomplish this GHG reduction or climate
"mitigation" goal, the City adopted a Cazbon Dioxide (CO2) Reduction Plan in 2000 which
outlined steps for Chula Vista to reduce energy and fuel use at municipal facilities and
throughout the community. In 2008, seven new climate mitigation measures were adopted by
City Council to augment past efforts by improving energy and water efficiency, expanding
renewable energy systems, converting to more fuel efficient and alternative fuel vehicles, and
designing transit-friendly, walkable communities. Overall, the City's climate protection
programs and policies have helped Chula Vista reduce GHG emissions from municipal
operations by 47% and community per capita emissions by 27% compared to 1990 levels. As a
result, the City has been recognized for its climate-related accomplishments by multiple external
organizations such as the US Environmental Protection Agency, ICLEI-Local Governments for
Sustainability, California Sustainability Alliance, California Center for Sustainable Energy, San
Diego Gas & Electric, Sierra Club, and Earthworks San Diego.
To complement these climate mitigation efforts, City Council directed staff in October 2009 to
reconvene a Climate Change Working Group (CCWG) -comprised of residents, businesses, and
community representatives - to develop a list of recommended strategies to reduce Chula Vista's
vulnerability to expected local climate change impacts (known as climate
"adaptation"). Expected impacts include hotter and drier weather, diminished imported water
supplies, more poor air quality/heat wave days, more frequent wildfires, shifts in habitat and
species distribution, and increased rates of sea level rise. These impacts were identified in the
San Diego Foundation's Focus 2050 Study which synthesized the most recent, science-based
information pertaining to climate change trends and the resulting vulnerabilities to the region.
The State of California also analyzed future statewide climate change impacts through its
Climate Adaptation Strategy (2009) and has directed local governments to begin assessing their
community's vulnerability to climate change impacts and to begin integrating these impacts into
land use decisions. By minimizing the risks associated with climate impacts now, future costs
and public health concerns can be avoided and/or minimized.
The reconvened CCWG, which was established as a subcommittee of the City's Resource
Conservation Commission, included some members from the previous working group
augmented with additional members to reflect the group's new climate adaptation-related focus
areas. Stakeholders participating on the CCWG included representatives from development
companies, business associations, energy and water utilities, environmental organizations, and
education institutions. The group held 11 public-noticed meetings between December 2009
through August 2010 to review potential impacts and identify over 180 opportunities to reduce
these risks. In addition, the CCWG hosted 2 public workshops on climate adaptation planning to
solicit additional feedback which attracted over 30 community participants. The CCWG was
further supported by regional experts, climate scientists, and staff from multiple municipal
departments.

In October 2010, the Climate Change Working Group presented their 11 recommended Climate
Adaptation Strategies (Appendix A) to City Council to address climate change vulnerabilities
and solutions related to energy and water supplies, public health, wildfires, biodiversity, coastal
resources, and the local economy. As a result, City Council directed staff to develop more
detailed implementation plans for the 11 recommendations which would outline implementation
steps, timelines, and costs. These detailed plans, which would be created by a multi-departrnent
team and reviewed by applicable City Commissions, would be presented to City Council for
future consideration within 180 days.
This document outlines staff s general approach for implementing the 11 recommended Climate
Adaptation Strategies. For each strategy, a specific implementation plan has been created which
includes the following sections:
Overview - A review of potential climate change impacts, the original CCWG
recommendation to address these impacts, and how it relates to the proposed
program/policy
Program Strategy - An in-depth description of the programmatic approach for
implementing the proposed program policy to reduce future risks and costs from climate
change impacts including outreach activities and required municipal regulatory steps
Performance Metrics -The metrics which will be tracked and reported to quantify the
performance of the program/policy
Timeline - A general timeline of important milestones as the program/policy is
implemented
Budget & Financing -The required funding to implement the program/policy as
proposed by City staff
As proposed, initial implementation of all 11 strategies will be phased in over the next 3 years
and will cost approximately $554,000. Of these initial costs, approximately $273,500 or 49%
will be supported by existing funding sources and will allow at least 8 of 11 strategies to be fully
or partially implemented. Ongoing implementation of the 11 strategies will cost approximately
$337,000 annually and will be partially covered (49%) through existing funding sources as well.
If the Climate Adaptation Strategies' plans are approved by City Council, staff will partially
implement the measures based on available funding and will pursue additional external funding
sources to support full, long-term implementation. Therefore, approval of the plans will not
create a new impact to the General Fund and in some cases may generate utility cost savings for
municipal operations (and the community) over time. Furthermore, the cost of "no action' could
be significant in the long term through public and private infrastructure damages (due to
wildfires and sea level rise), public safety and health issues (due to extreme heat, wildfires, and
poor air quality), and energy and water shortages (due to higher local demand). Potential

external funding sources include federal and state grants, utility public goods chazges, and
greenhouse gas offset/mitigation fees. A City Council-approved implementation plan will
potentially make Chula Vista more competitive in soliciting these funding sources because the
plans provide a broader framework and an explicit commitment which many funding agencies
seek in applicants. In addition, City staff will continue to identify new opportunities to leverage
existing municipal efforts and work plans to cost-effectively implement the Climate Adaptation
Strategies.

STRATEGY #1: COOL PAVING
OVERVIEW
By 2050, annual average temperatures in the San Diego region are expected to increase up to 4.5
degrees Fahrenheit with summer temperatures increasing even higher. This temperature shift
will likely amplify the "urban heat island effect" and its negative community impacts. The urban
heat island effect, which was first recognized in the 19th century by climatologists who measured
differences in cities where natural vegetation and trees had been removed, is a phenomena in
which the air in urban azeas can be 4-5°F hotter than in surrounding undeveloped areas.z As
natural landscapes are replaced with buildings, rooftops, and pavement that absorb, store, and
then radiate heat, the amount of energy used for cooling purposes, the concentration of smog,
and the general discomfort of residents and visitors within the community increases. In areas
with tall buildings and narrow streets, heat can be trapped and airflow reduced between
structures. In addition, waste heat from air conditioning, vehicles, and industrial processes
contributes further to an urban community's heat load. As such, the Climate Change Working
Group recommended that the City should develop an ordinance incorporating reflective (or ``cool
paving") into all municipal projects (parking lots and streets) and new private pazking lot
projects over a specific size. Cool pavements refer to a range of established and emerging
paving materials which store less heat and have lower surface temperatures compazed with
conventional products.
To address these climate change impacts related to the urban heat island effect, City staff will (1)
perform a comprehensive study to evaluate and test multiple reflective pavement technologies
and (2) develop options, based on the study's results, for incorporating cool pavement
technologies into municipal capital improvement and development parking lot standards.
PROGRAM STRATEGY
The following specific actions will be pursued by City staff over the next 24 months:
1. Cool Paving Study & Test Area -The Public Works Department (Operations &
Engineering), with the assistance of outside technical consultants and the US
Environmental Protection Agency, will perform a pilot project to evaluate multiple
reflective or "cool" pavement strategies to help inform creation of new policies for
municipal paving capital improvement projects and private parking lot projects. In siting
a potential test area, the City will explore opportunities to focus on areas which already
need pavement repair or replacement. The pilot project will consider:
a. The current and future technologies and their applications -possible use of test
sites with long term performance measurement
b. Costs associated with reflective paving (for both municipal operations &
developers)
c. Thorough understanding of the benefits/drawbacks of cool paving techniques
d. Installation techniques and reflective paving standards
e. Short and long term performance and comparison with current practices

j. Benefits of street and parking lot landscaping (shade trees)
2. Cool Paving Study Results & Standards Options -Based on the study results, staff will
develop options for incorporating reflective pavement into all municipal projects and
private parking lot projects over a specific size. The options will be presented to City
Council for review and consideration.
PERFORMANCE METRICS
Although the development of specific performance metrics would be informed by the proposed
cool pavement study, below aze some potential metrics that could be tracked and reported on an
ongoing basis to quantify the performance of the "Cool Pavement" strategy:
• Temperature reduction of cool versus traditional paving materials in test azeas
• Total square feet of paved surfaces incorporating cool paving technologies
TIMELINE
The initial implementation of this strategy will occur over a 24-month period (summarized in
figure below). City staff will develop and release a Request for Qualifications (RFQ) for
consultants to assist in designing and implementing a cool pavement study between May and
July 2011. By the end of 2011, the study will begin and last 12-36 months (estimated). With the
results of the study and field tests, staff will prepaze policy options for cool pavements which
will be vetted through the various City commission and presented to City Council for final
consideration.

BUDGET & FINANCING
The proposed components' initial implementation costs aze estimated to be approximately
$115,000 for staffing and consultant fees to further evaluate cool paving opportunities and policy
options (summarized in table below). Potential ongoing annual expenses are estimated at
$5,000. These costs may be covered partially through existing external founding sources, but
additional funding will be required for full implementation. Any cool pavement policy presented
to the City Council for future consideration would include a more robust cost analysis on
municipal operations for ongoing implementation of the strategy. This analysis will also identify
costs to any particular stakeholder group (such as residents, businesses, and developers).

STRATEGY #2: SHADE TREES
OVERVIEW
As previously described in this report, annual average temperatures are expected to increase up
to 4.5 degrees Fahrenheit with summer temperatures increasing even higher by 2050.1 These
higher temperatures, combined with a larger regional population, will cause peak electricity
demand to grow by over 70% compared to current levels. Shade trees contributing to a robust
urban forest aze useful in addressing both higher temperatures and energy demand by acting as a
natural cooling mechanism for urban areas. In addition, canopy-forming trees help reduce storm
water runoff, provide habitat for wildlife, and increase property values? As such, the Climate
Change Working Group recommended that Chula Vista adopt a shade tree ordinance, so that
shade trees aze incorporated into all municipal improvement projects and all private development
parking lot projects. The CCWG also noted that any new ordinance should be flexible to adjust
to project features such as solar carports or other regulations such as the existing landscape water
conservation ordinance.
To address these climate change impacts related to higher air temperatures and energy demand,
City staff will (1) develop a shade tree policy for future City Council consideration, (2) amend
the Municipal Landscape Manual to be consistent with the new policy, and (3) ensure that the
recently-updated Design Manual is consistent with the new policy.
PROGRAM STRATEGY
The following specific actions will be pursued by City staff over the next 12 months:
1. Municipal Shade Tee Policy -The Land Development Division's Landscape Section will
create a new policy which emphasizes shade trees in all municipal improvement projects
and private development parking lot projects. City staff has determined that a formal
City Council policy (rather than an ordinance) would be the most effective way to ensure
that the use of shade trees is incorporated into all future projects to help mitigate and
adapt to climate change impacts. The new policy will be developed as described in the
context of Theme 5 of the General Plan (Healthy & Sustainable Environment) and will
specifically address tree species selection, maintenance considerations, water usage, and
planting standards. The new policy will also be designed to allow implementation
flexibility, so that site-specific factors (such as ensuring retail signage is still visible from
public right-of--way) aze properly addressed. A cost impact analysis on municipal
operations and private developers will be presented prior to final approval. The analysis
will include opportunities to integrate reduced minimum parking requirements as part of
an incentive package. An approved shade tree list will be incorporated into the policy by
reference and be developed in partnership with the City's Arborist and Urban Forestry
Division. Staff will also review successful urban forestry programs in other local
jurisdictions to inform policy development.

A variety of related City Council policies will be superseded by adoption of a new shade
tree policy:
576-OS -Tree Preservation Policy
576-09 -Landscaping for City Buildings Policy
576-08 -Median landscaping Policy
576-07 -Street Tree Maintenance
576-06 -Palm Tree Preservation Policy
576-04 -Approved Tree Policy
576-03 -Tree Planting Policy
576-O1 -Tree and Shrubbery Policy
2. Landscape Manual Update -The Chula Vista Landscape Manual is the City's primazy
guidance document for all development projects in terms of the design, installation, and
maintenance of their landscaped areas. To align the Landscape Manual with the new
City Council policy on shade trees (described above), the Land Development Division's
Landscape Section will update the manual accordingly. The new shade tree guidance
provided in the Landscape Manual will take into consideration limited landscape water
budgets, tree maintenance requirements, and available root/canopy space. These updates
will also be coordinated with modifications to reflect new state laws requiring lower
water use plant palettes and on-site storm water capture and treatment. Finally, the new
Landscape Manual's shade tree requirements for parking lot projects may provide
exemptions if cool (see Climate Adaptation Strategy #1) or porous (see Climate
Adaptation Strategy #S) pavements are provided, or some combination of the three. The
new requirements may also provide reduced minimum parking standards as part of an
incentive package.
3. Design Manual Update -The City's Design Manual will be reviewed and updated (if
necessazy) by the Development Planning Division to be consistent with the new shade
tree requirements outlined in the revised Landscape Manual and new City Council shade
tree policy. However, it is envisioned that most of the desigr. criteria will be captured in
the Landscape Manual, while the Design Manual will just reference the Landscape
Manual for compliance guidance.
PERFORMANCE METRICS
The following metric will be tracked and reported on an ongoing basis to quantify the
performance of the "Shade Trees'' strategy:
• # of new projects incorporating the new shade tree standard
TIMELINE
The implementation of this strategy will occur over an 8-month period (summazized in figure
below). After the draft shade tree policy is circulated for public feedback, staff will present the
draft policy to the various City Commissions and, ultimately, to the City Council in July 2011 for
review and consideration. After City Council's approval of the new policy, the Landscape

The proposed components' initial implementation costs are estimated to be $40,000 for staffing

sources. Staff does not foresee any ongoing, additional costs to the City associated with
implementing this climate adaptation strategy. However, any new policy presented to the City
Council would include a more robust cost analysis on municipal operations and identify costs to
any particulaz stakeholder group (such as residents, businesses, and developers).

STRATEGY #3: COOL ROOFS
OVERVIEW
Annual average temperatures are expected to increase up to 4.5 degrees Fahrenheit by 2050 with
summer temperatures increasing even higher.l These higher temperatures, combined with a
lazger regional population, will cause peak electricity demand to grow by over 70% compazed to
current levels. Every house changes the microclimate around it by retaining the sun's heat and
contributing to the urban heat island which increases discomfort for everyone, requires an
increase in the aznount of energy used for cooling purposes, and increases the formation and
concentration of smog. Cool roofs, which are made of highly reflective and emissive material
that can remain approximately 50 to 60°F cooler than traditional materials, can help address the
problem of heat islands by lowering the ambient temperatures inside and outside of buildings,
providing a more comfortable and healthy environment, and reducing energy use for air-
conditioning.z As such, the Climate Change Working Group recommended that the.City should
require and provide incentives (such as contributing to the City's enhanced energy code
requirements) fox new residential development with air-conditioning systems to install ENERGY
STAR cool roof technology.
To address these climate change impacts related to higher air temperatures and energy demand,
City staff will further evaluate cool roofing options and propose amendments to municipal
building codes to incorporate cool roofs for new residential developments with air-conditioning
(AC) systems. Staff will also evaluate further the CCWG's suggestion to provide cool roofing
incentives and will offer recommendations for future City Council consideration.
PROGRAM STRATEGY
The following specific actions will be pursued by City staff over the next 9 months:
1. Municipal Building Code Update -The Building Division will propose amendments to
the City's Green Building Standards -Chula Vista Municipal Code Chapter 15.12 - to
require cool roofs on new residential developments (single-family and multi-family) with
air conditioning. Any new standazd would not apply to retrofitted roofs on existing
residential buildings. Chula Vista Municipal Code Chapter 15.12 adopts and amends the
2010 California Green Building Standazds Code (CalGreen). Currently, cool roofing is a
voluntary measure in CalGreen, and staff will be proposing to make these measures
mandatory. The CalGreen residential voluntary measures for cool roofs are categorized
into two tiers: Tier 1 and Tier 2. Tier 1 standards meet ENERGY STAR and California
Energy Commission (CEC) minimum specifications for cool roofs, while Tier 2
standazds require higher efficiency levels than Tier 1. Staff will evaluate the cost and
benefit of both tiers and, based on staff s findings, will recommend to City Council which
standards to adopt. Staff will also evaluate the cost and benefit of requiring cool roofs on
new residential developments without AC systems. Homes built without an AC system
may later have a system installed and because cool roofs provide a cooler, more
comfortable indoor/outdoor environment, requiring cool roofs on homes without an AC

system could potentially negate the need to have an AC system installed in the future by
occupants. Finally, any new cool roof standazd will be designed to not impede the
installation of solar photovoltaic or other renewable energy systems on the roof space.
The majority of all new residential developments in the City, excluding some multi-
residential units, will have sloped roofs with concrete or clay file roofing material. Based
on staffs preliminary research, the majority of concrete and clay file roofing that is
locally available meets or exceeds minimum ENERGY STAR specifications at zero to
minimal incremental cost compazed to traditional "non-cool" products. It also should be
noted that many of the existing homes in the City's newer areas have concrete or clay file
roofing that meet minimum ENERGY STAR specifications. Finally, cool roof products
are currently available in a wide vaziety of types, shapes, and colors.
Even though staff is not proposing amending the Califomia Energy Code to require cool
roofs, the Califomia Energy Commission has informed the City that the CEC will have to
approve any cool roof ordinance before it can take effect. The CEC's involvement is
triggered because cool roofing is one of the options available to builders under the
performance method of compliance with the Energy Code and it plays a role in the
energy efficiency of buildings. The CEC approval process is similar to the City's past
process with adopting its increased energy efficiency standards which involved acost-
effectiveness analysis, a City Council determination that the proposed requirements are
cost-effective, and submittal of the proposed requirements to the CEC after the
ordinance's first reading by City Council. The final CEC review and approval process
can take up to three months.
PERFORMANCE METRICS
The following metric will be tracked and reported on an ongoing basis to quantify the
performance of the "Cool Roofs" strategy:
• # of new residential units incorporating cool roofs
TIMELINE
The implementation of this strategy will occur over a 9-month period (summarized in figure
below). With the help of a consultant, Building Division staff anticipates having the cost-
effectiveness study completed in May 2011 and a proposed ordinance to City Council in August
2011, after being vetted through vazious City Commissions. After City Council's approval of
first reading, staff will submit the proposed requirements to the CEC for approval (anticipated
for November 2011). After CEC approval, staff will bring the ordinance back to City Council
for second reading and adoption in December 2011. If approved by City Council, the new
requirements will take effect in January 2012 which is 30 days after formal adoption.

STRATEGY #4: LOCAL WATER SUPPLY & REUSE
OVERVIEW
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 limit imported water availability, increase utility costs for residents and
businesses, and lead to higher demand for local water sources. As such, the Climate Change
Working Group recommended that Chula Vista should educate its residents and businesses about
the benefits and appropriate uses of local water supplies (including recycled water, groundwater
desalination, and onsite water reuse systems) and further integrate recycled water (if available)
and onsite water reuse systems into new development and redevelopment plans.
To address these water-related climate change impacts and reduce future risks and costs, the
City, in close coordination with local water districts, will (1) evaluate and propose municipal
building code amendments to incorporate single-source gray water "stub-outs" in new residential
buildings and indoor recycled water in new commercial buildings, (2) develop an educational
guide for the general public about proper use of gray water systems, (3) create an incentive
(using external funding sources) to promote onsite water reuse, and (4) update the City's water-
related plans to reference and promote recycled water and onsite water reuse systems.
PROGRAM STRATEGY
The following specific actions will be pursued by City staff in partnership with Sweetwater
Authority and the Otay Water District over the next 2 yeazs:
1. Water Reuse Building Codes & Standards -The Building Division will evaluate and
propose new ordinances to incorporate gray water plumbing "stub-outs" (all residential
properties) and dual plumbing for indoor recycled water use (commercial properties in
eastern area) for new development projects. These new codes will contribute to meeting
the City's Green Building Standards for indoor and outdoor water use efficiency and be
complemented by education and outreach to developers and building permit applicants.
A cost impact analysis on municipal operations and private developers also will be
presented prior to final ordinance approval.
Based on new state regulations, gray water systems, which typically collect water from
showers, non-food sinks, and clothes washers, can be installed at residences and be used
to irrigate landscaped areas, thus lowering demand for imported water. The proposed
strategy will require a simple stub-out for clothes washers on a new home's exterior, so
that homeowners can more easily install PVC pipes to water their landscaping. The stub-
out requirement will also help ensure that homeowners are properly using asingle-source
gray water system, because currently there is no municipal permit needed for this system
type. The new standard will be developed to place special emphasis on maintaining
proper public health and safety and avoiding any urban runoff concerns. Staff also

expects that the new standazd will take into consideration the residential building type
(single-family detached, single-family attached, and multi-family), lot size, soil type, and
laundry room location in the new home. Based on information from the City of Tucson
which incorporated a similar requirement in 2008, the incremental cost for the stub-out
during construction is estimated to be less than $200 per home. Finally, the City will
coordinate with the applicable regulatory agencies in developing the new standazds for
gray water stub-outs.
Currently, recycled water is provided by the Otay Water District in the eastern section of
Chula Vista and used mainly for landscaping on commercial properties, street medians
and pazkways, parks, and open space districts. To broaden the use of this drought-
resistant, local water source, the Building Division will evaluate and propose a new
standard expanding recycled water to indoor commercial uses. Specifically, the new
standard will integrate dual plumbing systems in new commercial buildings in Otay
Water District's service territory. The new system will allow recycled water to be used
for indoor plumbing flush fixtures such as toilets and urinals and for mechanical systems
such as HVAC cooling towers. The new standard will be developed to place special
emphasis on maintaining proper public health and safety and be adjusted for different
commercial building sizes, uses, and location (i.e. access to a recycled water delivery
pipes). Finally, the City will coordinate with the applicable regulatory agencies in
developing the new standards for indoor recycled water plumbing.
2. Single-Source Gray Water Best Practices - To help community members who are
interested in utilizing single-source gray water systems, the Conservation Division in
partnership with the Building Division will develop a "best practices" manual describing
proper installation methods for installing the systems at residential properties. This user-
friendly document will address single-source 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 systems'
effectiveness, protecting human health, and avoiding water runoff The Gray Water Best
Practices Guide will be available at the City's Permit Counter and on the CLEAN website
and will be distributed to the public at community events and through landscape-related
educational opportunities (such as on-site NatureScape certifications and Composting
classes).
3. Onsite Water Reuse Incentive -The Conservation Division will collaborate with the local
water districts to create an "onsite Water Reuse Incentive Fund" to provide rebates for
onsite water reuse. The fund will specifically target retrofitting existin residences and
businesses (which are not addressed through the new stub-out requirement described
above) to maximize onsite water collection and reuse, thus decreasing reliance on
imported water sources and helping to lower monthly utility costs. Examples of potential
incentive uses include providing rebates for the purchase of rain barrels and single-source
gray water (clothes washer) conversion kits. Similar to the City's current Home
Upgrade, Carbon Downgrade Appliance Exchange Rebate Program, the new rebates
could be structured as point-of--sale discounts at local retailers in order to support the
local Chula Vista economy and to streamline the participation process for interested

residents and businesses. Potential funding sources for the Onsite Water Reuse Incentive
Fund could include water efficiency grants, partnerships with non-profit agencies, and/or
other funding mechanisms, as available.
4. Landscape Manual & Water Conservation Plan Guidelines Updates -Outdoor water
conservation for new construction and major renovations is guided by a variety of
municipal documents at various stages in the development approval process. At the sub-
area plan stage, development projects with 50 or more dwelling units (or equivalent) must
complete Water Conservation Plans to outline their strategies for maximizing indoor and
outdoor water use efficiency. At the permit review stage, new development and
redevelopment projects must comply with the City's Landscape Manual which directs
project proponents to design and install landscaping (plant palettes and irrigation
systems) that meet a designated water budget and design standards. To further promote
recycled water and onsite water reuse systems, the Advanced Planning and Land
Development Divisions will revise the Water Conservation Plan Guidelines and the
Landscape Manual, respectively, to explicitly incorporate and promote recycled water
and onsite water reuse systems (such as gray water and rain water harvesting) into the
project design and review process. As part of the revisions, Homeowner Associations'
CC&Rs will also be required in the future to include information concerning onsite water
reuse opportunities to help educate new homeowners and lower their utility costs.
PERFORMANCE METRICS
The following metrics will be tracked and reported on an ongoing basis to quantify the
performance of the "Local Water Supply & Reuse" strategies:
• # of new residential units incorporating a gray water stub-out
• # of new commercial buildings incorporating indoor dual plumbing for recycled water
• Amount of incentive funds distributed for retrofitting existing buildings with onsite water
collection and reuse systems
TIMELINE
Implementation of the above-mentioned components will occur over a 12-month period
(summarized in figure below). Between May and October 2011, the new water reuse codes and
standards will be drafted for review by various City Commissions, and ultimately for ordinance
consideration by the City Council. Likewise, updates to the Water Conservation Plan Guidelines
and Landscape Manual will be vetted through the various City commission prior to City Council
consideration. Once the new codes and standards are adopted, the Gray Water Best Practices
Guide will be finalized to ensure consistency between documents. Finally, between April 2011
and April 2012, City staff will work to develop and seek initial, external financial support for an
Onsite Water Reuse Incentive Fund.

updating codes and policies, creating associated guidebooks, developing an incentive fund,
training staff, and initial community outreach efforts. Annual costs cover ongoing outreach and
program administration efforts. As part of the Water Reuse Codes & Standazds component, it
should be noted that plan review and inspection costs for dual plumbing aze estimated to be 2-3
hours per project (not including the cost of a potentially required annual inspection program) and
development fees would most likely need to be adjusted to recover these additional staff costs.
Finally, any new policy or ordinance presented to City Council will also identify costs to any
particular stakeholder group (such as residents, businesses, and developers).

STRATEGY #5: STORM WATER PREVENTION & REUSE
OVERVIEW
San Diego County's water resources have many beneficial uses and play a major role in the
lifestyle and economy of the region. By 2050, climate change will likely alter regional
precipitation patterns.' This precipitation variability will impact watersheds by altering water
runoff and sediment movement flows. Because of urbanization and its associated activities,
pollutants are discharged with these flows into the City's storm drainage systems, creeks, rivers,
San Diego Bay, and the ocean and reduce the beneficial uses of these water bodies for the Chula
Vista community. As such, the Climate Change Working Group recommended that Chula Vista
revise its storm water regulations and applicable municipal codes to efficiently manage higher
concentrations of pollutants in urban runoff by minimizing water waste, using natural landscapes
to help drain or reuse runoff, and by ensuring that irrigations systems are properly installed and
maintained.
To address these storm water-related climate change impacts and reduce future risks and costs,
the City will (1) update municipal codes to prohibit landscape runoff flowing into storm drains
and receiving water bodies, (2) develop new guidelines to promote the reuse of pipe flushing
water at construction sites, (3) create incentives to reward Low Impact Development projects
which capture and reuse storm water onsite, and (4) investigate opportunities for broader reuse of
storm water via the City's conveyance system.
PROGRAM STRATEGY
The following specific actions, which are above and beyond federal and state regulations, will be
pursued by City staff in partnership with local water districts and other regional agencies over
the next 24 months:
1. Landscape Water Waste Reductions -Currently, Chula Vista Municipal Code (CVMC)
Section 14.20.110 exempts landscape irrigation, irrigation wafer, and lawn watering from
discharge prohibitions. However, testing on samples taken from storm drainage systems
throughout the City during the past few years indicates that nitrate, which is a commonly-
used fertilizer, is a persistent pollutant in urban runoff. Landscape runoff, a likely source
for nitrates as well as phosphorous and pesticides, is commonly caused by overwatering
or improperly functioning irrigation systems. In fact, the State Water Resources Control
Board has conducted water sampling and testing in Poggi Creek and Sweetwater River
under the Surface Water Ambient Monitoring Program, and has determined that test
results warrant placing Poggi Creek and Sweetwater River on the list of impaired water
bodies (303(d) list) for toxicity. To implement this strategy, the Storm Water
Management Division will update CVMC Section 14.20.110 to remove landscape
irrigation, irrigation water, and lawn watering from any property type from the list of
exempted discharges. This regulatory update will be complemented by public outreach
activities to help educate the community about the new guidelines. Similar to the City's

current approach in managing storm water compliance, all violators are first given a
written warning before any citation is issued.
2. Construction Site Water Waste Reductions - As part of construction and grading
activities, pipe flushing is a common practice which is conducted after the installation of
all water and sewer pipes. It is intended to remove any debris or sediment that may have
entered the pipes during construction work. Currently, the effluent from pipe flushing is
allowed to discharge into the City's storm drainage systems and eventually into a
receiving water body (such as a creek, river, or bay). As a result, all debris and sediment
that is accumulated in the pipes are dischazged to storm drainage systems (in violation of
CVMC Section 14.20.100) and gallons of potable water, which can be re-used in
construction activities, is wasted. To implement this strategy, City staff will develop a
program to encourage developers and contractors to re-use line flushing effluent from
construction activities for on-site beneficial uses such as dust control, moisture control
for soil compaction, and temporary imgation of hydro-seeded slopes. The City may
partner with the Associated General Contractors of San Diego and the local water
districts to develop the program.
3. Low Impact Development Incentives - When a natural parcel of land is developed,
increased impervious areas alter the site's hydrology such that peak flow rates and
durations are increased (known as hydromodification), along with the pollutants that are
carved in the storm water. Recent experience shows that utilizing natural systems to
manage urban runoff, known as Low Impact Development (LID), provides one of the
most effective methods for preventing pollutant and sediment dischazges to storm water
conveyance systems. Sediment is considered a pollutant because it clogs fish gills and
smothers bottom-dwelling aquatic life. LID concepts include infiltration, bioretention,
vegetated swales and roofs, porous pavements, and rain harvesting.
Currently, the Chula Vista Development Storm Water Manual includes requirements for
incorporating Low Impact Development features in new development and major
redevelopment. However, developers and consultants generally fail to take full
advantage of the site's potential for LID features because dedicated land is required for
such features, costs may be (or perceived to be) higher than traditional methods, and
breaking from past practices is not easy. In order to encourage developers to incorporate
LID features in their project designs to the fullest extent possible, City staff will provide
incentives through expedited permitting process or another non-monetary means (such as
reduced minimum parking requirements) to proj ect proponents.
4. Beneficial Storm Water Reuse -Preliminary estimates indicate that on a typical dry
summer day, about 430,000 gallons of water flows through the City's storm water
conveyance systems. Dry weather flow is generated either by urban activities such as
landscape over-irrigation and caz washing or natural processes such as groundwater
seepage which can be exacerbated by landscape irrigation infiltration. Storm water
conveyance system flows may have various potential uses, such as irrigation of open
spaces, public pazks, and golf courses, or cooling, washing, or other activities related to
industrial facilities. Urban runoff reuse also contributes to minimizing the community's

reliance on imported water and to reducing pollution in creeks, rivers, and the San Diego
Bay. The presence of certain constituents such as dissolved salts may, however, require
water treatment before reuse. To implement this strategy, City staff will conduct a
feasibility study to determine dry weather flow sources, potential uses, possible site
locations, as well as the economic feasibility of various reuse scenarios. The study will
also assess the impact of diverting dry season flow on wildlife and sensitive habitats.
PERFORMANCE METRICS
The following metrics will be tracked and reported on an ongoing basis to quantify the
performance of the "Storm Water Prevention & Reuse" strategies:
• # of construction sites conserving and re-using pipe-flushing water
• # of developments taking advantage of incentives to incorporate LID features in their
projects
• # of gallons of urban runoff diverted for reuse
• # of properties upgrading or adjusting their irrigation systems to prevent over-watering
runoff or over-spray
TIMELINE
Implementation of the above-mentioned components will occur over a 24-month period
(summarized in figure below). All municipal code updates referenced above will be drafted for
ordinance consideration by the City Council after being vetted through vazious City
Commissions. Updates to the Chula Vista Development Storm Water Manual will be made 12
months after the adoption of the next National Pollutant Dischazge Elimination System (NPDES)
Municipal Permit for the San Diego Region.

STRATEGY #6: EDUCATION & WILDFIRES
STRATEGY #7: EXTREME HEAT PLANS
OVERVIEW
If current trends continue, San Diego County's risk from wildfires will become greater by 2050.
This increased susceptibility to wildfires will be driven by warmer spring temperatures extending
the fire season and drier vegetation conditions (from prolonged drought periods) intensifying
available fuel sources. This combination will likely increase up to 20% the number of days
annually with ideal conditions for lazge-scale fires. In addition to wildfires, extreme heat days
in Chula Vista could triple over the next 40 years, which will lead to further public safety and
health concerns including poor air quality (from ground level ozone) and infectious disease
transmittal (from mosquitoes and rodents). ~ As such, the Climate Change Working Group
recommended that Chula Vista actively educate the general public and the business community
about the impacts of climate charlge using existing City and community partner outreach
mechanisms with a special emphasis on making homes more resilient to wildfires, incorporating
poor air quality day notifications, and educating businesses about employee heat illness risks.
Furthermore, the City should include "extreme heat" events as a significant emergency in its
public safety planning efforts with a special emphasis on serving vulnerable populations and
supporting a robust network ofenergy-secured "Cooling Centers."
To address these wildfire and public health-related climate change impacts and reduce future
risks and costs, the City will (1) leverage municipal and partner agencies' outreach mechanisms
to broaden wildfire education in the community, (2) revise the City's existing Emergency
Response Plan and the Multi-Jurisdictional Hazard Mitigation Plan to include extreme heat
events, and (3) establish a extreme heat and poor air quality notification system for residents and
businesses.
PROGRAM STRATEGY
The following specific actions will be pursued by City staff in close collaboration with
community partners over the next 4 years:
1. Wildfre Outreach & Education -The Fire Department, with assistance from the
Conservation Division, will leverage existing municipal programs and community
organizations to broaden the public distribution of wildfire educational materials to
support wildfire preparedness and prevention. Existing outreach venues that will be
updated to include the expanded wildfire education component include, but aze not
limited to, Chula Vista Fire Explorers, Chula Vista CERT Program, Southwestern
College Work Experience Program, Chula Vista Fire Safe Council, and Conservation
Division's Home Energy Assessment and NatureScape programs. All outreach measures
will be designed to provide a cleaz and consistent message to community members about
wildfire safety. In addition to traditional mazketing approaches (such as community
newsletters and brochures), the City will maximize its use of door-to-door canvassing and

social media (such as Facebook). All educational and outreach materials will be
produced in English and Spanish formats.
2. Emergency Response Plan & Hazard Mitigation Plan Updates -The City's existing
Emergency Response Plan, a component of the Chula Vista Emergency Operational Plan,
provides a framework for local public safety response in case of a large-scale emergency.
To help prepare the community for higher frequencies and duration of extreme heat days
in the future, the Fire Department will revise the City's Emergency Response Plan to
include extreme heat events and the appropriate response actions to mitigate the impacts
from the events. As part of the update process, the City will evaluate the need to expand
"cooling centers" in Chula Vista to serve vulnerable populations such as the elderly,
young, and sick and to incorporate renewable energy and/or energy storage for electricity
reliability in case of blackouts. A similar revision will also be completed for the Multi-
Jurisdictional Hazazd Mitigation Plan by the Fire Department during its next regulazly
scheduled update in 2015. This countywide plan identifies risks and ways to minimize
damage by natural and manmade disasters through enhancing public awareness, creating
a decision tool for management, promoting compliance with State and Federal program
requirements, enhancing local policies for hazard mitigation capability, and providing
inter-jurisdictional coordination.
3. Poor Air Quality & Extreme Heat Notifications - In addition to health risks from heat
exhaustion and heat stroke, exhaust from vehicles and industrial sources cause ground-
level ozone to accumulate at high concentrations during extreme heat events. These
harmful concentration levels can trigger a variety of public health problems including
chest pain and coughing, and can worsen bronchitis, emphysema, and asthma. To help
prepare the community for more frequent extreme heat and poor air quality days, the
Conservation Divisions will establish a procedure for notifying residents, businesses, and
community organizations about these events. The notification system will build off the
San Diego Air Pollution Control District's air quality monitoring and forecasting system
and utilize the City's Nixle and Lyris messaging platforms, as well as its social media
sites (such as Facebook).
PERFORMANCE METRICS
The following metrics will be tracked and reported on an ongoing basis to quantify the
performance of the "Education & Wildfire" and "Extreme Heat Plans" strategies:
• # of wildfire education materials distributed
• % increase in community awareness from outreach and education (based on surveys)
• # of residents & businesses subscribed to notification system (through Nixle, Lyris, &
other messaging distribution methods)
TIMELINE
Implementation of the above-mentioned components will occur over a 4-year period
(summazized in figure below). Between May and October 2011, existing community and
municipal outreach efforts will be revised to include wildfire education and aCity-administered

notification system for extreme heat and poor air quality days will be established. The
Emergency Action Plan and Multi-Jurisdictional Hazard Mitigation Plan will be updated to
include extreme heat events by Apri12012 and April 2015, respectively.

STRATEGY #8: OPEN SPACE MANAGEMENT
OVERVIEW
With a rich natural diversity, San Diego County may be home to more plants and animals -many
of them imperiled -than any other county in the continental United States. The region's beaches,
canyons, mountains, and deserts support an amazing variety of plants and animals, some of
which are found nowhere else on the planet. This great biodiversity is already under stress from
human population growth and land use changes that have broken up and reduced species habitat
to fragmented areas. By 2050, the impacts of climate change -more severe and frequent
wildfires, extended droughts, sea level rise, higher temperatures, and increased air pollution -
will add to the pressures on habitats and their associated species. As a result, the locations
where the temperature, moisture, and other environmental conditions aze suitable for a particular
species will shift. Chula Vista's open space areas include landscaped azeas within developments,
pazks and recreation areas, and open space that has been set aside as a preserve for sensitive
biological resources. In order to assess and reduce impacts associated with climate change on
pazks and open space and their associated ecosystems, the Climate Change Working Group
recommended that the City seek opportunities to partner with the Resource Agencies, non-profit
organizations, and/or adjacent public land managers to monitor and manage/restore ecosystems
(as funding becomes available) to ensure long-term habitat connectivity, species resilience, and
community recreational opportunities.
To address these open space-related climate change impacts and reduce future risks and costs,
the City, in close coordination with local partners, will (I) update the Otay Ranch Preserve
Monitoring and Plans to actively manage and mitigate these impacts, (2) amend the Otay Valley
Regional Pazk Concept Plan to ensure climate change impacts aze considered into future park
development and management, and (3) continue the City's transition to low water use
landscaping within medians, pazks, and open space azeas.
PROGRAM STRATEGY
The following specific actions will be pursed by City staff in partnership with the County of San
Diego, City of San Diego, US Fish and Wildlife Service, California Department of Fish and
Game, Otay Valley Regional Park Citizen Advisory Committee, Otay Ranch Preserve Steward
(RECON), JPB Development, and Otay Land Company over the next 18 months:
1. Otay Ranch Preserve Monitoring and Plan Amendments (Phase 2) -The Advanced
Planning Division will collaborate with the County of San Diego and the Otay Ranch
Preserve Steward in the preparation of the Otay Ranch Preserve's annual work plans to
document potential vegetation and species diversity changes as a result of climate
change. These annual plans outline the active (such as habitaUspecies surveys, invasive
species removal, and native plant restoration) and passive (such as litter abatement and
fencing) management priorities for the given calendar yeaz. As part of this climate
adaptation strategy, specific management and monitoring actions in response to observed
climate changes will also be incorporated into the annual work plans, as necessary, to

ensure long-term habitat and species viability. Finally, the Otay Ranch Resource
Management Plan (Phase 2) will also be revised to incorporate policies and objectives
which promote the evaluation of the impacts of climate change on open space and
recreational opportunities as these uses are planned in or adjacent to the Otay Ranch
Preserve.
2. OVRP Concept Plan & Trail Design Guidelines -The Otay Valley Regional Pazk
(OVRP) Concept Plan & Trail Design Guidelines provide a blueprint for the long-term
management of the multi-jurisdictional park and for the development of its trail network,
respectively. As part of this climate adaptation strategy, the Advanced Planning Division
will work with OVRP partners to amend the OVRP Concept Plan to include criteria for
educational opportunities in the pazk such as interpretive centers/stations and written
materials. All educational materials will incorporate information about climate
adaptation programs and opportunities in the OVRP. The Advanced Planning Division
will also work with the partners to amend the OVRP Trail Design Guidelines to allow for
climate adaptation in the design of future trails and active recreation areas by
incorporating a planting pallet that can withstand varied climates from heavy rain/flood to
drought and alternative access points and trail rerouting for existing and new trails in the
case of flooding
3. Open Space Management -Currently, the City's Open Space Division manages a
network of open space areas which include urban canyons, parkways, and medians. To
address climate change impacts especially related to extended drought periods, the Open
Space Division will continue and expand its efforts to install state of the art irrigation
systems (i.e. low flow, web-based smart controllers, master valves, and flow sensors) in
these areas. Staff will also seek additional opportunities to convert turf and other
groundcover materials to drought tolerant or drought resistant plant materia]s throughout
the City's Community Facility Districts (CFDs). Large-scale mulch applications which
can help retain moisture soil and lower water needs will be utilized in some CFD azeas,
where appropriate. Finally, any improvements to CFDs will be supported by external
funding sources or their existing funding levels and any water cost savings will be
retained by the CFD
PERFORMANCE METRICS
The following metrics will be tracked and reported on an ongoing basis to quantify the
performance of the "Open Space Management" strategies:
• # of surveys conducted within the Otay Ranch Preserve to document potential vegetation
and species diversity changes as a result of climate change
• # of interpretive centers/stations in the OVRP that include information about climate
adaptation programs and opportunities
• # of brochures that have been prepazed for the OVRP that include information about
climate adaptation programs and opportunities
• # of linear feet of new state of the art irrigation systems installed within CFD areas
• # of low flow, web-based smart controllers, master valves, and flow sensors installed

TIMELINE
The implementation of this strategy will mainly occur over an 18-month period (summarized in
figure below). In June 2011, revisions to the Otay Ranch Reserve Management Plan's annual
work plan process will commence with the new work plans beginning the following month. By
the end of 2011, revisions to the OVRP concept Plan and Trail Design Guidelines will also begin
and continue through 2012. Finally, the conversion of open space areas to more water efficient
plant pallets and irrigation will occur over an 8-year period (not displayed in figure below).

STRATEGY #9: WETLANDS PRESERVATION
OVERVIEW
By 2050, warmer temperatures and less rain in the San Diego County will keep the region highly
vulnerable to prolonged drought periods. This precipitation variability will stress riparian
wetlands and may alter sediment movement from surrounding watersheds. Along coastline and
bays, estuarine wetlands will additionally be impacted by rising sea levels. These impacts from
rising sea levels will be exacerbated during storm events. As a result, the locations where the
temperature, moisture, and other environmental conditions are suitable for wetlands and their
associated species will shifr.~ In order to reduce impacts associated with climate change on
wetlands, the Climate Change Working Group recommended that when preserving or restoring
coastal and riparian wetlands, the City should take steps to incorporate adequate upland or
transition habitats to accommodate shifts in wetlands coverage and help ensure public access due
to sea level rise and other climate change impacts as informed by biological studies and
Resource Agency consultation.
To address these wetlands-related climate change impacts and reduce future risks and costs, the
City, in close coordination with local partners, will (1) evaluate the feasibility of monitoring
local wetlands species ranges and abundances in response to climate change impacts, (2)
incorporate wetlands "migration" in habitat management and restoration design criteria in the
future Bayfront Natural Resources Management Plan, and (3) revise the Otay Valley Regional
Pazk's Habitat Restoration Plan and Non-native Plant Removal Guidelines to include strategies
for climate change adaptation issues.
PROGRAM STRATEGY
The following specific actions will be pursed by City staff in partnership with South County
Land Managers, Port of San Diego, Environmental Health Coalition, City of San Diego, County
of San Diego, and the Otay Valley Regional Park Citizen Advisory Committee over the next 18
months:
Regional Biological Monitoring - Currently, the Advanced Planning Division
collaborates with other public agencies such as the US Fish & Wildlife Service,
California Departrnent of Fish & Game, and other local jurisdictions to monitor the
region-wide network of Multi-Species Conservation Plan preserve land. The vazious
agencies coordinate and standardize their biological monitoring of the abundance and
distribution of key habitats and species. These types of surveys are typically performed
at least annually on preserve lands. As part of this climate adaptation strategy, the City
will use this collected data to help gauge the response of sensitive habitats and species to
climate change impacts. In addition, the City will work with its project partners to
determine the feasibility of correlating species distributions to microclimate patterns in
order to more robustly track climate change impacts on preserve lands region-wide.

2. Bayfront Natural Resources Management Plan (NRMP) Preparation - In collaboration
with the Port of San Diego and community stakeholders, the City will prepare a
management plan for the Bayfront development area. The Bayfront Natural Resources
Management Plan (NRMP), is being prepared to guide the management of the bayfront's
biological resources and to preserve its natural resources from indirect and direct
development impacts. As part of its this work effort, the City will also ensure that
management strategies are included into the NRMP which promote the resiliency of the
Bayfront ecosystems against future sea level rise and other climate change impacts.
Potential resource management strategies may include incorporating transitional habitats
into wetland restoration projects, including buffers between sensitive habitats and
development, and protecting upland areas adjacent to wetlands.
3. OVRP Habitat Restoration Plan and Non-native Plant Removal Guidelines -The City
will work with the other OVRP Partners (City of San Diego & County of San Diego) to
amend the OVRP Habitat Restoration Plan Guidelines and Non-native Plant Removal
Guideline to provide for climate change adaptation strategies. Specifically, the
amendments to these guidelines will include policies to encourage management activities
for wetlands and other habitats that are responsive to climate change impacts through
restoration designs, non-native species removal methods, and public access planning.
PERFORMANCE METRICS
The following metrics will be tracked and reported on an ongoing basis to quantify the
performance of the "Wetlands Preservation" strategies:
• # of surveys performed to monitor shifts in local species range and diversity resulting from
climate adaptation.
• # of habitat restoration areas within the OVRP where climate change impacts were
incorporated into project designs
TIMELINE
The implementation of this strategy will occur over an 18-month period (summarized in figure
below). In February 2011, staff will begin preparation of the Natural Resources Management
Plan which should be finalized by the end of the year. The OVRP Habitat Restoration Plan and
Non-native Plant Removal Guidelines' revision process will commence in December 2011 with
final City Council review and consideration scheduled for December 2012 after being vetted
through various City Commissions.

STRATEGY #10: SEA LEVEL RISE & LAND DEVELOPMENT CODES
OVERVIEW
Between 1900 and 2000, sea levels rose 6 inches on average along San Diego County coastlines
and bays. Over the next 40 years, sea level rise rates are expected to increase with local sea
levels 12 to 18 inches higher than their current levels. Higher sea levels can result in increased
erosion, more frequent flooding and property damage, loss of wetland habitats, and fewer
waterfront public access options. These impacts from rising sea levels will be exacerbated
during storm events. As such, the Climate Change Working Group recommended that Chula
Vista amend its land development codes and CEQA guidelines to incorporate climate change-
related sea level rise into future development and municipal infrastructure projects' design and
review.
To address these climate change impacts and reduce future risks and costs, the City will (1)
revise its grading ordinance to consider a project's vulnerability to future sea level rise and
flooding events, (2) modify its Subdivision Manual to ensure that storm water/drainage
infrastructure can address future sea level rise and flooding impacts, and (3) ensure that
environmental review and CEQA procedures are consistent with these changes.
PROGRAM STRATEGY
The following specific actions will be pursued by City staff over the next 12 months:
1. Update the Grading Ordinance -The Chula Vista Grading Ordinance provides guidance
to developers and engineers by regulating grading, drainage, and erosion control on
private and public property to safeguard public health, property, and general welfare and
to prevent water pollution and sedimentation of the City's water resources. To meet the
ordinance's requirements, project proponents complete and submit a grading plan to
demonstrate their compliance. As part of the implementation of Climate Adaptation
Strategy #10, Land Development Division staff will update the grading ordinance to
require that all "tidally influenced" projects account for anticipated sea level rise for the
next 50 years (currently projected at 1.5' of sea level rise) into their project development
and grading plans. The costs of additional grading on the front end are relatively small
compared to having to remove and/or replace all infrastructure in "tidally influenced"
areas in the future. The revised ordinance will require an update to the Subdivision
Manual every 5 years to account for changes in sea-level rise predictions over time using
the best available data. The revised ordinance will be presented to City Council for final
review and consideration.
2. Update the City's Subdivision Manual -The purpose of the Subdivision Manual is to
provide developers and engineers a guide for land development processing within the
City of Chula Vista. The Subdivision Manual covers development processes beginning
with the filing of a Tentative Map through approval and recordation of Final Maps. To
account for increased risk from sea level rise, Land Development Division staff will
' San Diego Foundation. "Focus 2050 Study: San Diego's Changing Climate." 2008
Climate Adaptation Strategies 36 of 42
Final Implementation Plans
9-39
update the Subdivision Manual to add requirements for development projects within
"tidally influenced" areas to demonstrate, prior to Tentative Map Approval or grading
plan approval, that:
a. the storm drain system for the project is designed to maintain at least a dry driving
lane in each direction during a 50 yeaz design storm that occurs at the highest high
tide with a projected 1.5' feet of sea level rise
b. the storm drain system for the project is designed to prevent any property damage
with a 100-year storm occumng at the highest high tide with a projected 1.5' of
sea level rise.
3. Update the Ciry's Environmental Review Procedures -For any project or activity that
could potentially directly or indirectly impact environmental quality, the City is required
to review and mitigate the impacts under the California Environmental Quality Act
(CEQA). To ensure that environmental review and CEQA procedures aze consistent with
the Grading Ordinance and Subdivision Manual revisions referenced above, the
Advanced Planning Division will review and update (if necessary) the threshold language
to the environmental review procedures for development projects located in "tidally
influenced areas." The thresholds may also be amended on a 5-yeaz basis, so that the
threshold is refined as sea level rise information and prediction technology improves.
Initial thresholds aze estimated at an additional 1.5' on top of the highest high tide for a
project with a 50-year lifespan.
PERFORMANCE METRICS
The following metric will be tracked and reported on an ongoing basis to quantify the
performance of the "Sea Level Rise & Land Development Codes" strategy:
• # of development projects complying with the new standazds
TIMELINE
The implementation of this strategy will occur over a 12-month period (summarized in figure
below). In May 2011, staff will begin to develop a revised Grading Ordinance and Subdivision
Manual which will be distributed for public comment. Both the Grading Ordinance and
Subdivision Manual will be vetted through various City Commissions before being presented to
the City Council for review and consideration in July and December 2011, respectively. Finally,
CEQA procedures will be updated (if necessary) by April 2012.

STRATEGY #11: GREEN ECONOMY
OVERVIEW
By 2050, Chula Vista and the surrounding region will likely be impacted by a variety of climate
change im~acts such as hotter and drier weather, higher sea levels, and more frequent and intense
wildfires. Climate change impacts create new issues which local communities and, in
particular, businesses need to address and prepare for in order to reduce future risks and costs.
These issues can include higher insurance premiums due to greater flooding or wildfire risks,
more expensive utility costs due to higher energy and water demand, lower productivity due to
more employee sick days from frequent extreme heat and poor air quality days. As such, the
Climate Change Working Group recommended that Chula Vista should provide assistance and
non-monetary incentives to help businesses manage climate change risks and to attract
businesses that provide "green" products or services into Chula Vista.
To address these climate change-related concerns from businesses, the City, in close
coordination with local business stakeholders, will (1) revise the municipal purchasing policy to
more robustly promote the procurement of "green" products and services, and to give preference
for purchases from local Chula Vista businesses, (2) revise existing environmental outreach
programs to businesses to include recommendations on how to reduce future climate change
risks, and (3) continue to pursue the recruitment and retention of "green" businesses and
manufacturers in Chula Vista.
PROGRAM STRATEGY
The following specific actions will be pursued by City staff in partnership with local business
associations over the next 6 months:
1. Green Procurement Policy & Process -The Environmental Services Division, in
partnership with the Conservation Division and the Finance Department, will revise the
City's "Municipal Environmentally Preferable Purchase Policy" to greater emphasize the
procurement of a broader array of eco-friendly goods and services leveraging Chula
Vista's annual supplies and services budget of approximately $58 million (includes
capital, redevelopment, and sewer fund budgets). The existing policy, which was revised
in 2008, encourages City divisions and departments to show a purchasing preference for
products and services which incorporate resource efficiency (i.e. raw materials, energy,
and water) and pollution prevention into their design, manufacturing, use, and disposal.
However, staff has struggled with tracking the policy's implementation and assessing its
efficacy. As part of the revision process, the policy will be redesigned to address these
concerns and to provide City divisions and departments a more user-friendly tool for
complying with the City Council policy. Finally, the policy will modified to give
preference for purchases from local Chula Vista businesses, especially those participating
in the City's CLEAN Business program.

9-42
2. CLEAN Business &FREBE -Chula Vista offers businesses free assistance to help them
become more sustainable, lower their monthly utility costs, and ultimately improve their
bottom line allowing them to hire more employees and expand their operations locally.
The Free Resource & Energy Business Evaluation (FREBE) program, which is a required
component of the annual business licensing process for storefronts and offices, provides
businesses an on-site review of their energy and water use. Through the evaluation,
trained City staff are able to identify opportunities for participants to improve their
energy and water efficiency and take advantage of special rebate and financing programs.
Annually, over 1,000 evaluations are completed through the FREBE program and
approximately 95% of past participants would recommend the program to other
businesses. The Chula Vista CLEAN Business program builds off of the FREBE
program by recognizing local businesses who have demonstrated leadership in energy
and water conservation, pollution prevention, and materials management. These
businesses have voluntarily improved their operations and/or facilities to meet high
standards of sustainability and efficiency. Through implementation of this strategy
component, these business-oriented environmental outreach efforts will be revised to
include an assessment of a business's "vulnerability" to future climate change impacts
and recommendations to reduce associated future risks and costs. Businesses will not be
required to implement any of the recommendations identified by staff in either program.
3. Green Business Recruitment & Retention -The Economic Development Division will
continue to pursue the development of an Eco-Industrial/Green Business Park. The
physical development would incorporate green building techniques and renewable energy
infrastructure, with the ultimate goal of recruiting and attracting new business operations
and manufacturing that specializes in clean technologies, products, and services. This
project will create a business climate that is attractive to technology companies, by
providing the companies with the required infrastructure, skilled workers, research
institutions, and financing mechanisms.
As part of the Economic Development Division's efforts to promote local business-to-
business transactions, staff will work to connect current clean tech-oriented Chula Vista
businesses with each other through formal and informal peer networks. Economic
Development staff will work with new and existing businesses to identify existing and
attract new business services, supply chain, and support services for the business
community. Further, staff will work with current Chula Vista businesses to identify
opportunities for new "green" product and service development.
PERFORMANCE METRICS
The following metrics will be tracked and reported on an ongoing basis to quantify the
performance of the "Green Economy" strategies:
• # of businesses participating in the FREBE and CLEAN Business programs annually
• Value of municipal environmentally-preferred purchases annually
• # of businesses which are located in Chula Vista offering "green" products or services

for review and consideration. Likewise, the FREBE and CLEAN Business programs will be
updated by October 2011 in order to incorporate recommendations to help businesses prepare for
climate change impacts. Finally, the Economic Development Division will continue working to
attract and retain businesses focused on "green" products and services.

APPENDIX A
CLIMATE CHANGE WORKING GROUP
Recommendations on Climate Adaptation Strategies
SUMMARY
Below are the Climate Change Working Group's final recommendations on climate adaptation
strategies that the City of Chula Vista should implement to reduce the community's future risk from
climate change-related impacts (numbering does not reflect priorities):
1. Develop an ordinance incorporating reflective paving (or "Cool Paving") into all municipal
paving projects (parking lots & streets) and new private parking lot projects (over a
specific size).
2. Develop an ordinance incorporating shade trees into all municipal projects (parking lots
8 streets) and new private parking lot projects (over a specific size). The new ordinance
should include a deviation for solar carports (or other shade structures), be complementary to
existing free tree programs, and potentially be incorporated into the existing Landscape Water
Conservation regulations.
3. Require and provide incentives (such as contributing to City's enhanced energy code
requirements) for new residential development with air-conditioning systems to install ENERGY
STAR cool roof technology.
4. Educate residents and businesses about the benefts and appropriate uses of local water
supplies (including recycled water, groundwater desalination, and onsite water reuse
systems) and further integrate recycled water (if available) and onsite water reuse systems
into new development and redevelopment plans.
5. Revise the City's Stormwater regulations and applicable landscape/building codes to efficiently
manage higher concentrations of pollutants in runoff by minimizing water waste, using
natural landscapes which help drain or reuse runoff, and by ensuring that irrigation systems are
properly installed/maintained.
6. Actively educate the general public and the business community (through community
newsletters, websites, public events, and signage) about the impacts of climate change and
what the community is doing to address impacts. In close coordination with the Fire
Department, special emphasis should be given to using existing outreach mechanisms
(Southwestern College's Services Learning program, Americorps/CERT training, and City
environmental outreach programs) to expand public education on making homes more resilient
to wildfires.
7. Include "extreme heat" events as a significant emergency in Chula Vista's Emergency
Response Plan (short term) and its portion of the County's Multi-Jurisdiction Hazard Mitigation
Plan (long term), and redefine "extreme heat" events with a special emphasis on serving
vulnerable populations, supporting a robust network of "Cooling Centers", incorporating poor
air quality day notifications, educating businesses about employee heat illness risks, and
integrating renewable energy sources into emergency/cooling centers.
S. In order to assess and reduce impacts associated with climate change on parks and open
space and their associated ecosystems, seek opportunities to partner with the Resource
Agencies, non-profit organizations, and/or adjacent public land managers to monitor and
manage/restore ecosystems (as funding becomes available) to ensure long-term habitat
connectivity, species resilience, and community recreational opportunities

9. When preserving or restoring coastal and riparian wetlands, incorporate adequate upland or
transition habitats to accommodate shifts in wetlands coverage and help ensure public
access due to sea level rise and other climate change impacts as informed by biological
studies and Resource Agency consultation.
10. Use the outcome of the current San Diego Bay Climate Adaptation Study (being sponsored by
the San Diego Foundation and ICLEI) to revise the City of Chula Vista's Land Development
Ordinances (such as Grading Ordinance) and CEQA Guidelines to incorporate climate
change-related sea level rise 8 other flooding risks into future development and municipal
infrastructure projects' design and review.
11. Provide assistance and non-monetary incentives to help businesses manage climate
change risks and to attract businesses that provide "green" products or services into Chula
Vista.
If these recommendations are supported by City Council, City staff should develop more detailed
implementation plans for the measures. Within these plans, staff should outline implementation
steps, timelines, and cost estimates for each measure. These detailed implementation plans
should be presented to City Council for a final decision on whether to move forward with specific
measures.
BACKGROUND
In October 2009, City Council directed staff to reconvene a Climate Change Working Group
(CCWG) -comprised of residents, businesses, and community representatives - to develop a list
of recommended strategies for the City to reduce vulnerabilities to expected local climate change
impacts (known as "climate adaptation'). Expected impacts include hotter and drier weather,
diminished imported water supplies, more poor air quality/heat wave days, more frequent wildfires,
shifts in habitat and species distribution, and increased rates of sea level rise. The reconvened
CCWG, which was established as a subcommittee of the City's Resource Conservation
Commission (RCC), included some members from the previous working group augmented with
additional members to reflect the group's new climate adaptation-related focus areas:

The CCWG planning process was facilitated by Conservation & Environmental Services
Department staff with technical support from the Fire, Public Works, and Development Services
Departments.
PLANNING PROCESS
The CCWG met 11 times from December 2009 through August 2010 in public meetings at various
municipal locations. In addition to posting public notices prior to each meeting, an email notice was
sent to over 60 additional stakeholder groups and community members to invite them to attend the
meetings and provide feedback. The majority of these stakeholder groups had been involved in
the previous climate mitigation planning process in 2008. A notice was also published through the
City's Community Connections newsletter at the onset of the climate adaptation planning process
to help build community awareness about the CCWG effort. To solicit additional public feedback,
the CCWG hosted a public forum on June 16, 2010 at the Norman Park Senior Center. Over 30
community members attended the "open house" meeting and shared their opinions and priorities
for climate adaptation strategies.
The planning process was split into three phases -information gathering, risk assessment, and
strategies selection. During the first phase, the meetings featured presentations from CCWG
members and regional experts on the different adaptation topics. These presentations discussed
the current state of practices (i.e. "business as usual"), the predicted impacts to the San Diego
region from climate change based on the best available data, and the vulnerability of municipal
operations and the broader community to these impacts. Staff summarized this information into a
Climate Adaptation Planning Matrix for each focus area. In the end, the CCWG identified over 180
possible climate adaptation strategies.
In phase two, the CCWG assigned risk levels to each identified vulnerability in consultation with
researchers from the University of California San Diego. Risk was defined as a product of the
likelihood of the climate change impact occurring and the consequence of the impact. Each factor
was scored from 1-5 and overall risk was categorized as "Low," "Medium," or "High." In addition,
various adaptation strategies to address each impact and vulnerability were vetted based on three
initial criteria: (1) strategy falls within the City's jurisdiction, (2) strategy is fiscally feasible (i.e. does
not rely on General Fund support for implementation), and (3) strategy does not duplicate or
contradict current climate mitigation measures.
In the final phase, CCWG members discussed and prioritized which strategies would be ultimately
included in their recommendations. Strategies that could be characterized as "no regret" actions or
actions having multiple co-benefts were regarded as high priority measures. The CCWG also
worked to combine multiple strategies into a single recommendation to broaden their positive
impact. Community members attending the meetings in this final phase were heavily involved in
the discussion and prioritization activities. Finally, the CCWG made a presentation to the Resource
Conservation Commission at their September 13'" meeting to receive feedback and further inform
their final recommendation selection (Appendix A). The CCWG also received a joint comment
letter from the Environmental Health Coalition and San Diego Coastkeeper (Appendix B).
NEXT STEPS
The Climate Change Working Group's final list of recommendations to help Chula Vista "adapt" to
climate change impacts are designed to reduce future risk and costs within energy and water
supply, public health, wildfires, ecosystem management, coastal infrastructure, and the local
economy sectors. The adaptation strategies complement the City's current climate mitigation
measures and many strategies will also contribute to lowering citywide greenhouse gas emission
levels. Due to the limited resources available to the CCWG, a formal cost analysis for each
recommendation could not be completed. As such, the CCWG recommends that City Council
direct staff to develop more detailed plans to better define implementation costs, critical steps, and
timelines for future City Council review and consideration.

APPROVING PARTIAL IMPLEMENTATION OF THE STRATEGIES
BASED ON CURRENT FUNDING LEVELS, (3) AUTHORIZING
STAFF TO PURSUE ADDITIONAL FUNDING OPTIONS, AND (4)
DIRECTING STAFF TO RETURN TO COUNCIL WITHIN 180 DAYS
WITH AN IMPLEMENTATION UPDATE
WHEREAS, the City of Chula Vista has long understood the threats of climate change to
its community and has established itself as a leader amongst municipalities in planning to reduce
or "mitigate" citywide greenhouse gas emissions; and
WHEREAS, despite efforts both locally and globally to mitigate emissions, some level of
climate change will still occur and have noticeable impacts on the San Diego region; and
WHEREAS, expected impacts include hotter and drier weather, diminished imported
water supplies, more poor air quality/heat wave days, more frequent wildfires, shifts in habitat
and species distribution, and increased rates of sea level rise; and
WHEREAS, the City Council directed the Chula Vista Climate Change Working Group
(CCWG) -comprised of businesses, residents, and community representatives - to identify
Chula Vista's vulnerability to expected local climate change impacts and to develop strategies to
reduce future risks and costs from these impacts (known as climate "adaptation"); and
WHEREAS, the City Council accepted the CCWG's recommendations and directed City
staff to develop implementation plans within 180 days; and
WHEREAS, the Climate Adaptation Strategies' Implementation Plans were developed
by amulti-department team and provide a more detailed framework for each strategy's
implementation components, timelines, and costs; and
WHEREAS, staff integrated the feedback from various City Commissions and other
stakeholders in finalizing the plans; and
WHEREAS, the proposed Climate Adaptation Strategies will help to reduce the City's
future risks and costs from expected local climate change impacts.
NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Chula Vista
that it (1) adopts the Climate Adaptation Plans, (2) approves partial implementation of the
strategies based on current funding levels, (3) authorizes staff to pursue additional funding
options, and (4) directs staff to return within 180 days with an implementation update.
