SUBJECT: Climate Adaptation Strategies' DRAFT Implementation Plans.
Attached are the DRAFT implementation plans for the Climate Adaptation Strategies which
were originally developed by the City's Climate Change Working Group (CCWG). The CCWG
— comprised of businesses, residents, and community representatives — worked over a 12 -month
period to identify Chula Vista's vulnerability to expected local climate change impacts (known
as climate "adaptation"). Through 13 public meetings and forums, the CCWG ultimately chose
I I recommended strategies to reduce future risks and costs from these impacts related to energy
and water supplies, public health, wildfires, biodiversity, coastal resources, and the local
economy. In October 2011, the City Council accepted the CCWG's recommendations and
directed City staff to develop implementation plans within 180 days.
The Climate Adaptation Strategies' DRAFT implementation plans, which were developed by a
multi -department team, provide a more detailed framework for each strategy's implementation
components, timelines, and costs. The plans were developed to ensure that they complement
(without being redundant) Chula Vista's current climate "mitigation" measures to reduce
greenhouse gas emissions. Also, the plans were designed to build upon 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.
Finally, the implementation components for each strategy were developed to be flexible enough
for future modifications as new climate change impacts data and modeling becomes available to
Chula Vista.
The DRAFT implementation plans are being presented to the Board of Appeals and Advisors
(BOA&A) in order to solicit feedback on their general content and structure. The presentation to
the BOA&A will focus more on Cool Paving, Cool Roofs and Local Water Supply and Reuse
because these strategies will have direct impact on the design and construction of buildings. City
staff will also be vetting the plans through other City Commissions such as the Planning
Commission, the Chula Vista Redevelopment Commission, and the Resource Conservation
Commission. The plans do not provide specific ordinance or policy language for consideration
by the BOA&A (or other City Boards and Commissions) at this time. Rather, if the plans are

approved by City Council in April, staff would proceed with implementing the plans based on
available funding and develop the specific policy language which would then be presented to the
City Boards and Commissions and, ultimately, the City Council for future review and
consideration.
RECOMMENDATION: Recommend that City Council adopt the implementation plans and direct
staff to implement based on available funding.

Dear Mr. �va�l
The Otay Water District has appreciated the opportunity to work with your staff to develop achievable
climate change measures related to water use. Prior to the February 28, 2011 Resource Conservation
Committee, we were invited to meet with your staff to discuss any issues and concerns that we may have
with your draft Climate Adaptation Strategy Implementation Plans. The meeting took place on February 17
and during that meeting, the District had a number of suggestions that we felt would help improve the
implementation of the measures.
Attached are the District's comments related to Strategy's #4 and #5 of Chula Vista's Climate Change
Adaptation Strategies. We understand that additional meetings are planned, should the draft Implementation
Plans be approved by your City Council. Please continue to coordinate future meetings through William
Granger the District's Water Conservation Manager, He can be reached at (619) 670-2290 or at

CLIMATE ADAPTATION STRATEGIES
DRAFT Implementation Plans
February 2011
SUMMARY
The City of Chula Vista Inas long understood the threats of climate change to its community and
has established itself as a leader amongst municipalities in planning vie' 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'Gioup, - 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 lire 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 programa. Initial
implementation of all 11 strategies will be phased in over the next 3 years and will cost
approximately $2,041,879. Of these initial costs, existing funding sources will allow at least 7 of
11 strategies to be fully or partially implemented Ongoing implementation of the 11 strategies
will cost approximately 5380,000 annually and will be partially covered do ougb existing funding
sources as well. If the Climate ddaptation Strategies' plans are approved by City Council, staff
will implement the measures based on available funding and pursue additional external funding
sources to support full, long-term implementation.
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 Carbon 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
Climalo Adaptation Strategies I of 39
DRAFT Implementation Plans (February 23, 2011)
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, Siena 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 ,Grown 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. By minimizing the risks associated
with these 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 Oify'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 Chinate Change Woildg5 Giroup 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 ccommuy fill
a result, City Council directed staff to develop more
detailed implementation plans for fill I recommendations which would outline implementation
steps, timelines, and costs. These detailed plans, which would be created by a multi -department
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:

review of potential climate
change impacts, the
original CCWG
recommendation

change impacts including outreach activities and required municipal code or 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 implem e program/policy as
proposed by City staff
As proposed, initial implementation of all 11 strategies will be phased in the next 3 years
and will cost approximately $2,041,879. Of these initial costs, approximate X23,379 or 16%
will be supported by existing funding sources and will allow at lees[ 7 of I1 str �ejgles to be fully
or partially implemented. Ongoing implementation of the 11 strategies will cost approximately
$380,000 annually and will be partially covered through existing funding sources as well, It
should be noted that the majority of unfunded implementation costs are associated with a single
component of strategy #8 (Open Space Management). Excluding this strategy, existing funding
sources are able to provide approximately �9% and 79% of the necessary one-time and annual
budgets, respectively.
If the Climate Adaptation Strategies' plans are approved by City Council, staff will implement
the measures based on available funding and will pursue additional external funding sources to
support full, long -tens implementation. Potential external funding sources include federal and
state grants, utility public goods charges, 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 fimding 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 Clmmte 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 ` arban 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 areas can be 6-8°F hotter than in surrounding .undeveloped areas. As
natural landscapes are replaced with buildings, rooftops, and pavement that absorb, store, and
then radiate heat, the amount of energy used for cooling purposcs, the concentration of smog,
and the general discomfort of residents and visitors within the cpmtnunity 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 au ordinance incorporating reflective (or "cool
paving') into all municipal projects (parking lots and streets)''and new private parking lot
projects over a specific size. Cool pavements refer to a innge of established and emerging
paving materials which store.less heat and have lower surface temperatures compared 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 packing lot standards.
PROGRAM STRATEGY '
The following specific actions will be pursued by City staff over the next 24 months:
Coin Pm,ing Slariv. & Testdrea — The Public Works Department (Operations &
P.no>inecrine) will perform a pilot project to evaluate multiple reflective or "cool"
paN e hent strategies to help inform creation of new policies for municipal paving capital
improvement projects: and private parking lot projects. The project will consider:
a. The current and future technologies and their applications — possible use of test
sites with long term performance measurement
b. Costsassociated with reflective paving
a Thorough understanding of the benefits/drawbacks of cool paving techniques
d. Installation techniques
e. Short and long term performance and comparison with current practices
f. Reflective paving standards
g. Streets — residential vs. arterial and private vs. public facilities
h. Parking lots —private vs. public facilities
i. Maintenance of existing public and private facilities
j. Incentives opportunities for private owners to use reflective paving
applications/installations
Climate Adaptation Strategies 4 of 39
DRAFT Implementation Plans (February 23, 2011)
k. 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 are some potential metrias that could be hacked 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 areas
• Total square feet of paved surfaces incorporating cootpaving technologies
TIMELINE
The 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 mud last at least12. months. With the results of the study and
field tests, staff will prepare policy options for cool pavements which will be vetted through the
various City commission and presented to City,Courtcil for fund consideration by Much 2012.

BUDGET & FINANCING
The proposed components' initial implementation costs are 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 for
ongoing implementation of the strategy.

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. 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 are useful in addressing both higher temperatures and ener demand by acting as a
natural cooling mechanism for urban areas. In addition, canopy fo - res help reduce storm
water mnoff, provide habitat for wildlife, and increase propertyzv '4 es. As such, the Climate
Change Working Group recommended that Chula Vista adopt3.gyshade tree ordinance, so that
shade trees are 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:
Municipal Shade Tee Polio- - 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 nets 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. An approved shade nee list will be incorporated into the policy by
reference and be developed in partnership with the City's Arborist and Urban Forestry
Division. A variety of related City Council policies will be superseded by adoption of a
new shade nee policy:
576-05 -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
Climate Adaptation Strategies 7 of39
DRAFT Implementation Plans (February 23, 2011)
576-01 — Tree and Shrubbery Policy
2. Landscape Manual Update — The Chula Vista Landscape Manual is the City's primary
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/cano space. These updates
will also be coordinated with modifications to reflect new laws requiring lower
water use plant palettes and on-site storm water capture and if, atment. Finally, the new
Landscape Manual's shade tree requirements for parking lotprojects may provide
exemptions if cool (see Climate Adaptation Strategy #1) or porous (see Climate
Adaptation Strategy 45) pavements are provided, or 'ome combination of the three.
3. Design Manual Update — The City's Design Manual will be reviewed and updated (if
necessary) 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 design 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:
# ofnew projects incorporating the new shade nee standard
TIMELINE :•'
The implementation of this strategy will occur over an 8 -month period (summarized in figure
below). r: 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
Manual will be revised accordingly and presented to City Council for consideration in December
2011.

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. These higher temperatures, combined with a
larger regional population, will cause peak electricity demand to grow by over 70% compared 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 amount 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.
irconditioning. As such, the Climate Change Working Groul%recommended that the City should
require and provide incentives (such as contributing to the City's enhanced energy coda
requirements) for new residential development with air-conditioning systems to iti`s'iall ENERGY
STAR cool roof technology.
To address these climate change impacts related to higher air temperatures and energy demand,
City staff will (1) further evaluate cool roofing options and propose amendments to municipal
building codes to incorporate cool roofs fornew residential developments with air-conditioning
(AC) systems. Staff will also evaluate thither the CCWG's suggestion to provide cool roofing
incentives and will offer recommendations for fume City Council consideration.
PROGRAM STRATEGY
The following specific actions will bepursucd by City staff over the nest 9 months:
1. Milnicipal 131alding Cade Update — The Building Division will propose amendments to
the City's Grcen Building Standards -Chula Vieta Municipal Coda Chapter 15.12 - to
r cool roofs on new,r idential developments with air conditioning. Chula Vista
'cipal Code Chapter IS. .2 adopts and amends the 2010 California Green Building
rds Code (Ca1Green). Currently, cool roofing is a voluntary measure in CalGreen,
and a"ff 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 standards 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 indoorloutdoor 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.
l
Climate Adaptation Strategies 10 of 39
DRAFT Implementation Plans (February 23, 2011)
The majority of all new residential developments in the City, excluding some multi-
residential units, will have sloped roofs with concrete or clay tile roofing material. Based
on staffs preliminary research, the majority of concrete and clay tile roofing that is
locally available meets or exceeds minimum ENERGY STAR specifications at zero to
minimal incremental cost computed 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 variety of types, shapes, and colors.
Even though staff is not proposing amending the California En Code to require cool
roofs, the California Energy Commission has informed the Ci"' hat 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 Energ� Code and it plays a role in the
energy efficiency of buildings. The CEC approval-process is simiho to the City's past

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 (i£ 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-soktfce gray water "sure -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 Clay Water District over the next 2 years:
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
(fret City's Green Building Standards for indoor and outdoor water use efficiency and be
simlylemented by education and outreach to developers and building permit applicants.
Based on now state regulations, gray water systems, which typically collect water from
showers, uq n -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, se
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 a single -source
pay 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 standard 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
Climate Adaptation strategies 13 of39
DRAFT implementation Plans Tobruary 23, 2011)
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.
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 parkways, 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, . cled water to be used
for indoor plumbing flush fixtures such as toilets and urinalssnfor 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).
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 `list 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 now stub -out requirement described above) and at existing residences.
Special emphasis in the guides will also be placed on maximizing the systems'
effectiveness, protecting Bomanrun
health, and avoiding water off The Gray Water Best
Practices Guide wil I 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 NatureSeape certifications and Composting
classes).
3. Onsite Nater Reuse brcentive — The Conservation Division will collaborate with the local
w d scts to create an "Onsite Water Reuse Incentive Fund" to provide rebates for
e watenir reuse. 'Che fund will specifically target retrofitting existin residences and
u igesscs (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
Climate Adaptation Strategies 14 of 39
DRAFT Implementation Plans (February 23, 2011)
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 }eater 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. r ity costs.
PERFORMANCE METRICS
The following mctrics will be tracked and reported on an ongoing basis to quantify the
performance of the "Local Water Supply & Reuse" strategies:
• # ofnew 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 retro frttiog 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
eonsid@tion. 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.

training staff, and initial community outreach efforts. Annual costs cover ongoing outreach and
program administration efforts. As part of the Water Reuse Codes & Standards component, it
should be noted thatVan review and inspection costs for dual plumbing are 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.

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
mnoff and sediment movement flows. Because of urbanization and its associated activities,
pollutants are discharged with these flows into the City's storm drainststems, creeks, rivers,
Sit San Diego Bay, and the ocean and reduce the beneficial uses of these,, 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 mnoff by minimizing water waste, using natural landscapes
to help dmin or reuse runoff, and by ensuring that irrigations systems are properly installed and
maintained. ss
r
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 Lw Impact Development projects
which capture and reuse are= water onsite; and (4) investigate •. ortunities for broader reuse of
storm water via the City's conveyance systema; t
v
PROGRAM STRATEGI' '.
The following specific � ns, which are above and beyond federal and state regulations, will be
pursued by City staff ih,partnership with local water districts and other regional agencies over
the next 24 months:
Landscape Water Waste Reductions — Currently, Chula Vista Municipal Code (CVMC)
Section 14.20.110 exempts la rdscape irrigation, irrigation water, and lawn watering from
discharge prohibitions. However, testing on samples taken from storm drainage systems
[)iroughout the City during the past few years indicates that nitrate, which is a commonly -
used fertilizer, is a peesistent pollutant in urban runoff. Landscape runoff, a likely source
for nitratra 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 the list of exempted discharges. This
regulatory update will be complemented by public outreach activities to help educate the
community about the new guidelines.
Climate Adaptation Strategies 18 of 39
DRAFT Implementation Plans (February 23, 2011)
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 discharged to stone 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, staff will develop a
program to encourage developers and contractors to re -use hr Shing effluent for dust
control, landscape irrigation, or other potential beneficial uses its',
sites. The
City may partner with the Associated General Contractors 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 (]mown as hydrommlification), along with the pollutants that are
carried in the storm water. Recent experience shows that utilizing natural systems to
manage urban runoff, known as Low Impact Decehipment (LID), provides one of the
most effective methods for preventing pollutant and sediment discharges to stone water
conveyance systems. Sediment is considered a polluumt 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 hnpact 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 to
project 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 car 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 parks, 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
Climate Adaptation Strategies 19 of 39
DRAFT implementation Plans (Fehmary 23, 2011)
feasibility study to determine dry weather flow sources, potential uses, possible site
locations, as well as the economic feasibility of various reuse scenarios.
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 incorpora LID features in their
projects

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 large-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 change using existing "City and community par, ucr outreach
mechanisms with a special emphasis on making honics 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 of energy -secured "Cooling Centcrs."
To address these wildfire and public heahli related cltm'te change impacts and reduce future
risks and costs, the City will (1) leverage mynicipal and pLer agencies' outreach mechanisms
to broaden wildfire education in the community, (2) revise the City's existing Emergency
Response Plan and the(exjtt,"emc
-Jurisdictional 1-1azard Mitigation Plan to include extreme heat
events, and (3) establis heat and poor air quality notification system for residents and
businesses. _ Y '
PROGRAM STRATEGY
The following specific actions will be pursued by City staff in close collaboration with
community partners over the next 4 years:
I_ Wildfire 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 are 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 clear and consistent message to community members about
wildfire safety. In addition to traditional marketing approaches (such as community
newsletters and brochures), the City will maximize its use of door-to-door canvassing and
social media (such as Facebook).
Climate Adaptation Strategies 22 of39
DRAFT Implementation Plans (February 23, 2011)
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 Hazard Mitigation Plan by the Fire Department during its next regularly
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 hazardmitigation capability;,, and providing
inter -jurisdictional coordination.
3. Poor Air Quality & Extreme Heat Notifications - In addition to health risks from heat
exhaustion and beat 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 tbe>`Cily'.s Nixie and. Lyris messaging platforms, as well as its social media
sites (such as Facebook). k`
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
• # of residents & businesses subscribed to notification system (through Nixle, Lyris, &
other messaging distribution methods)
l
TIMELINE
Implementation of the above-mentioned components will occur over a 4 -year period
(summarized in figure below). Between May and October 2011, existing community and
municipal outreach efforts will be revised to include wildfire education and a City -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 April 2012 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 are suitable for a particular
species will shift. Chula Vista's open space areas include landscaped areas within developments,
parks 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
parka 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 for.. -term habitat cetnnectivity, species resilience, and
community recreational opportunities ,
J
To address these open space -related clinme chane impacts and reduce future risks and costs,
the City, in close coordination with local partners, will (1) update the Clay Ranch Preserve
Monitoring and Plans to actively manage and mitigate these impacts, (2) amend the Cray Valley
Regional Park Concept Plan to ensure climate change impacts are considered into fuhu e park
development and management, .and (3) continue the City's transition to low water use
landscaping within medians, parks, and open space areas.
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 RegionalTark Citizen Advisory Committee, Olay Ranch Preserve Steward
(RECON), JPB Development, and Olay Land Company over the next 18 months:
Otay Ranch Preserve Monitoring and Plans (Phase 2) — The Advanced Planning
Division will collaborate with the County of San Diego and the Cray 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 habitat/species surveys, invasive species removal,
and native plant restoration) and passive (such as litter abatement and fencing)
management priorities for the given calendar year. 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 Cray 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 Gory Ranch Preserve.
2, OW Concept Plan & Trail Design Guidelines — The Olay Valley Regional Park
(OVRP) Concept Plan & Trail Design Guidelines provide a blueprint for the long -tam
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 PI - to include criteria for
educational opportunities in the park such as interpretive c s/stations and written
materials. All educational materials will incorporate ormation about climate
adaptation programs and opportunities in the OVRP. ced Planning Division
will also work with the partners to amend the OVRP T _, esi 'delines to allow for
climate adaptation in the design of furore trail's`, and actio eation areas by
incorporating a planting pallet that can withstand varied climates fro rain/flood to
drought and alternative access points and trail. rerouting for existing an e trails in the
case of flooding
3. Open Space Management — Currently, the Ci an Space Division manages a
network of open space areas which include urban a ons, parkways, and medians. To
address climate change impacts especially relatedto ex'- ed drought periods, the Open
Space Division will continue and expand its efforts t , stall 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 oppodunities to convert turf and other
groundcover materials to drought tolerant or drought resistant plant materials throughout
the City's Community Facility .'District's ,(CFDs). Finally, large-scale mulch applications
which can help retain moisture soil and lower water needs will be utilized in some areas,
where appropriate.

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 e locations where the
temperature, moisture, and other environmental conditions are suitaU,4or wetlands and their
associated species will shift. In order to reduce impacts assomaQ with climate change on
wetlands, the Climate Change Working Group recommended that wh ppreserving or restoring
coastal and riparian wetlands, the City should take steps to nrcorpo aT ,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 biologioal studies and
Resource Agency consultation. .,
To address these wetlands -related climate change impacts and reduce future risks and costa, 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
Park's Habitat Restoration Plan and Non-native Plant Removal Guidelines to include strategies
for climate change adaptation issues.
x $
PROGRAM STRA1tArs,
The following specifins will be pursedtiy City staff in partnership with South County
Land Managers, Port �iego, 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 MOWtoring — Currently, the Advanced Planning Division
collaborates with other public agencies such as the US Fish & Wildlife Service,
California Department of Fish & Game, and other local jurisdictions to monitor the
region -wide network of Multi -Species Conservation Plan preserve land. The various
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
Climate Adaptation Strategies 29 of 39
DRAFT Implementation Plans (February 23, 2011)
management plan for the Bayfront development area. The Bayfront Natural Resources
Management Plan (NRNP), 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 Nan -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 ads on strategies. Specifically, the
amendments to these guidelines will include pol,tuy to encourage management activities
for wetlands and other habitats that are responsive to climate change*01$acts though
restoration designs, non-native species removal methods, and public access planning.
PERFORMANCE METRICS e=
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
THIVIELINE
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 th€ 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 1990 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 firhne development and municipal infrastructure projects' design and
review.
To address these climate change impacts and reduce finure risks and costs, the City will (1)
revise its grading ordinance to consider a project's' vulnerability to fimae sea I'evel 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:
Update the Grading Ordinance—'The Chn[a Vista Grading Ordinance provides guidance
to developers and engineers by regulating grading, drainage, and erosion control on
private and public property to safelpiard 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 fl/0, band Development Division staff will update the grading ordinance to
require that all "tidally influenced" projects account for anticipated sea level rise for the
next50years (currently projected at 1.5' of sea level rise) into their project development
and grading plans. Furthermore, 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 tiro best available data. The revised ordinance will be presented to City
Council for final review and consideration.
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
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:
Climate Adaptation Strategics 33 of39

a. the storm drain system for the project is designed to maintain at least a dry driving
lane in each direction during a 50 year design storm that occurs at the highest high
Ede 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 occurring at the highest high fide with a projected 1.5' of
sea level rise.
3. Update the City'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 are 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 -year basis, so that the
threshold is refined as sea level rise information and prediction technod�gy improves.
Initial thresholds are 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 standards
TIMELINE '`
The implementation of this strategy toll occur beer a 12 -month period (summarized in figure
below). In May 2011, staff will begin to develop a revised Grading Ordinance and Subdivision
Manual whralt,suii distributed for public comment. Both the Grading Ordinance and
Subdivismn Mj anual e vetted tluough 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 impacts 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 wild sks, more expensive
utility costs due to higher energy and water demand, lower produc ' due to more employee
sick days from frequent extreme heat and poor air quality days. the Climate Change
Working Group recommended that Chula Vista should provissistance and non -monetary
incentives to help businesses manage climate change risks andlo 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 (t) 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 STRATE
The following specific,ons will be pursued by City staff in partnership with local business
associations over the nex 6 months
1. Green proctoement policy & Process — The Environmental Services Division, in
partnership with the Conservation Division and the Finance Department, will revise the
City's "Municipal Psnvircrm tally Preferable Purchase Policy" to greater emphasize the
procurement of a broaderay of eco -friendly goods and services leveraging Chula
Vista's annual supplies and services budget of approximately $14 million. 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,
manufacnuing, 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.
2. CLEAN Business & FREBE —Chula Vista offers businesses free assistance to ]yelp 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.
Climate Adaptation Strategies 36 of39
DRAFT Implementation Plans (February 23, 2011)
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 sustainabihty 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 "vnInerability" to future climate change impacts
and recommendations to reduce associated furore 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
in&astmctarre, with the ultimate goal of reoruiting and attracting new business operations
and manufacturing that specializes in clean technologies, products, and services. 'Phis
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
oppornmities for new "green" product and service development.
PERFORMANCE METRICS
The following monies will be tracked and reported on an ongoing basis to quantify the
performance of the "Green Economy" strategies:
• # ofbusinesses participating in the FREBE and CLEAN Business programs annually
• Value of municipal environmentally -preferred purchases annually
• # ofbusinesses which are located in Chula Vista offering "green" products or services
TIMELINE
Implementation of the above-mentioned components will occur over a 6 -month period. Between
May and October 2011, a new municipal "green" procurement policy and process will be

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
& 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 Vee 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 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.
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 irrigaticnsystems 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.
B. 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
CCWG Final Recommendations on Climate Adaptation Strategies 1 ora
s -27-1n
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 & 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:

CCWG Final Recommendations on Climate Adaptation Strategies 2 of 3
9-2]-10
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 pasting 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 -benefits 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.
