COMMUNITY-BASED ADAPTATION
TO A CHANGING CLIMATE

COMMUNITIES ARE FACING A CHANGING WORLD - a world of warmer
temperatures, less predictable weather patterns, and rising sea levels. While
impacts vary by location, these and other impacts threaten the reliable
delivery of many community services. This resource discusses how climate
change is affecting community services, presents sample adaptation
strategies, gives examples of successful community adaptation actions, and
provides links to other key federal resources.
IMPACTS OF CLIMATE CHANGE ON LOCAL
GOVERNMENT SERVICES
Water Resources Management
Changing precipitation patterns and increased intensity of
rainfall events, storms and sea level rise are major elements
of a changing climate. These changes may degrade water
quality by increasing stormwater runoff, overflows of
separate and combined sewer systems, and stream bank
erosion. Community facilities, including drinking water and
wastewater treatment facilities, may be at risk due to more
frequent and severe flooding.
What are some water management adaptation
strategies?
• Account for future flood risk (e.g., using the new federal
flood standard) to protect drinking water and wastewater
treatment facilities
• Use green infrastructure to reduce stormwater runoff
• Preserve wetlands and establish vegetated buffers along
rivers and streams to reduce flooding, runoff, and erosion
Adaptation in Action: The 2008 Iowa River floods caused
extensive flooding along the Iowa City, Iowa riverfront.
After the flood, the community worked with state and
federal organizations, including the EPA, to develop a
master plan to rebuild the riverfront, promote equitable
development, and address challenges from a changing
climate. The "Riverfront Master Plan" reduces future
flooding risk by promoting green infrastructure; creating
a green buffer along the riverfront; and redirecting
growth away from the floodplain. By decommissioning a
flood-prone wastewater facility and expanding service
elsewhere, the city chose to adapt and reduce future
flooding risk. Several years after the floods, the
community continues to adapt and implement projects
under the Riverfront Master Plan.
Clean Air
A warming climate is expected to worsen air quality,
including ground-level ozone, which can aggravate lung
diseases and lead to premature death. Actions taken to
reduce ozone can both reduce greenhouse gas emissions
and yield adaptation benefits. People most at risk from
ozone exposure include people with asthma, children,
older adults, and those who are active outside, especially
outdoor workers. People with health conditions such as
obesity or diabetes may also have higher risk of ozone-
related health effects.
What are some clean air adaptation strategies?
• Reduce vehicle emissions by encouraging smart growth
development where people can work, live, and play
within a walkable area
• Upgrade existing municipal fleets to reduce air
pollutants

fc ["^AV-JP^ ft Adaptation in Action: The
Sustainable Salt Lake Plan
2015 reflects a broad and
ambitious agenda to protect
Salt Lake City's resources, enhance assets, and establish a
path towards greater community resiliency. The plan set
goals to improve air quality, protect community health,
and reduce particulate matter (PM) and ozone pollution.
The city adopted specific measures to decrease miles
traveled, reduce vehicle idling, and promote alternative
transportation. By employing these clean air strategies,
the city attained both adaptation and mitigation
benefits.
Waste Management and Exposure to Chemicals
Flooding from more intense and frequent storms due to
climate change increases the risk of releases from
contaminated sites and facilities where chemicals are
stored. Such areas include Superfund sites, brownfields,
and underground storage tank sites. The storms could
also result in the generation of more disaster debris,
further challenging local chemical and waste
management capacity.
What are some chemical and waste management
adaptation strategies?
• Develop crisis management plans to anticipate and
prepare for future extreme climatic events
• Account for climate risks in Brownfields cleanup and
redevelopment activities
• Integrate future flood risk projections into remedy
selection for hazardous waste cleanups
• Consider opportunities for toxic use reduction and safer
chemical storage strategies (e.g., not storing chemicals
in flood-prone locations such as basements) to reduce
the potential for chemical release during flood events
Adaptation in Action: Hurricane Irene dumped seven
inches of rainfall in 48 hours in 2011 at the American
Cyanamid Superfund site in New Jersey. The site,
already in an exceedingly wet state prior to the
hurricane, flooded. Although there was no major release
of contaminants, the flooding still caused significant
damage to the facility's infrastructure. To anticipate and
prepare for future events, officials decided to raise
critical infrastructure components to several feet above
previous flood events and to repair impoundments
to withstand a 1 -in-500 year flood event.
Emergency Response to Heat Events
Higher temperatures from climate change will increase
the risks of heat stress and heat-related deaths. Those
most vulnerable to extreme heat are the elderly, very
young children, infirm, poor, and socially isolated people.
Heat events trap air pollution and humidity, making it
difficult for those with respiratory illness to breathe.
Extreme heat events stress city services as well as
generally decrease labor productivity.
What are some heat event adaptation strategies?
• Develop an emergency heat plan to prepare city services
fora heat event
• Establish cooling centers to reduce heat stress and
heat-related deaths and illnesses
• Provide emergency notification and well-being checks to
protect the most vulnerable
• Incorporate heat island reduction strategies - such as
green or cool roofs, cool pavements, or increased
vegetation and trees - into long-term planning efforts to
help lower urban temperatures
Adaptation in Action: In 1995, more than 700 people
died during a five-day heat event in Chicago.This event
prompted Chicago to strengthen and update its heat
emergency response system.The city now encourages
residents to register for Notify Chicago, the city's text and
email emergency notification system. Residents can also
call 311 to have officials conduct well-being checks for
those who may need additional assistance. Disaster
preparedness and response trainings have also helped to
increase individual and community resilience and better
prepare Chicago for subsequent extreme heat events.
Transportation
Climate change may stress the transportation network
and infrastructure systems that are vital to any
community's economy. Extreme weather events and
flooding from intense downpours may damage
transportation infrastructure and increase the risk of
disruptions and delays in air, rail, and road transportation.

Sea-level rise and more severe storm surges may increase
the risk of coastal flooding, threatening critical
infrastructure such as airports, roads, rail lines, and tunnels.
What are some transportation adaptation
strategies?
• Identify vulnerable transportation systems to anticipate
and prepare for future events
• Account for future extreme weather, such as floods, in land
use planning (e.g., zoning ordinances) to protect
infrastructure and encourage climate-resilient
development
• Retrofit or relocate existing infrastructure to reduce risk of
disruptions
Adaptation in Action: Hurricane Sandy generated a storm
surge greater than nine feet in southern Manhattan when it
made landfall in 2012.The resulting flooding severely
damaged the city's
transportation network.
Portions of the city's
subway, light rail
network, tunnel system,
ferry system and La
Guardia and JFK airports
were out of service, or in
limited service, for
several days. New York
City has since updated
its vulnerability plan to
incorporate the latest
climate change projections.To reduce vulnerabilities, the
city has raised ventilation systems and is exploring erecting
flood barriers.
Natural and Environmental Resources
Climate change will alter the timing and duration of
seasonal events (e.g., snowfall, snowmelt) which can affect
recreation and tourism (e.g., viewing fall foliage, skiing, and
fishing for cold-water fish). Flooding and drought may
reduce the productivity of farmland and harm sensitive
environments (including habitat for ecologically, culturally,
or locally important species).
What are some natural and environmental
resource adaptation strategies?
• Assess tourism and recreational industry
vulnerability to anticipate economic risk
• Incorporate climate risk into land management strategies
to reduce the vulnerability of farmland and sensitive
environments
• Retrofit or relocate existing tourism facilities and outdoor
recreation infrastructure to prepare for climate change
Adaptation in Action:TheTennsylvania Climate
Adaptation Planning Report: Risks and Practical
Recommendations" includes tourism and outdoor
recreation as one of its four areas of focus for statewide
adaptation planning. A state-level working group assessed
the risks and vulnerabilities of the sector and
recommended specific actions that local government and
private business could do to adapt. Recommendations
included use of green infrastructure, improved stormwater
management, conserve and restore fish habitat,
demonstrate sustainable practices at public facilities, and
incorporate adaptation criteria into grant programs.
Cultural Resources
Climate change can damage important cultural resources
such as historic sites, cemeteries, and major landmarks.
Sea level rise, extreme weather events, and wildfires can
threaten cultural resources and traditions, including access
to, and availability of, food and culturally important lands.
What are some cultural resource adaptation
strategies?
• Identify cultural resources at risk to anticipate and
prepare for climate change
• Relocate or protect vulnerable cultural resources to
reduce the threats from climate change
• Engage the community to leverage local knowledge and
experience
Adaptation in Action: The National Capital Planning
Commission (NCPC) is the
federal planning agency
for America's capital,
home of many national
treasures (e.g., Jefferson
Memorial, Vietnam
Memorial, Martin Luther
King Memorial, Arlington
National Cemetery, and
the National Archives).

NCPCs Climate Adaptation Plan includes actions to
implement a wastewater and stormwater management
program that accounts for more frequent storms,
develop multi-purpose indoor and outdoor cooling
centers, and protect and increase designed landscapes,
forested areas and other managed green areas.
PROTECTING PEOPLE MOST AT RISK
Effective adaptation strategies should consider both
the risks from climate change and how they will affect
the community's most vulnerable. In particular:
Young Children - Children, especially those under the
age of four and unable to care for their own needs, will
disproportionately suffer from the effects of heat waves,
air pollution, infectious diseases, and trauma resulting
from extreme weather events.
Elderly & Infirm - The elderly, people with limited
mobility and those with pre-existing health conditions,
especially autoimmune disorders, are more susceptible
to cardiac and respiratory impacts of air pollution and
severe consequences from infectious diseases and
extreme weather events.
Low Income - Limited resources and a higher
prevalence of chronic health conditions, including heart
disease, obesity, and diabetes, place those with lower
income at higher risk of health impacts from climate
change.
Communities Dealing With Environmental
Justice Challenges -These populations have
historically been exposed to a combination of physical,
chemical, biological, social, and cultural factors that
have imposed greater environmental burdens on them
than those imposed on the general population. Climate
change is likely to exacerbate existing and introduce
new environmental burdens and associated health
impacts.
COMPREHENSIVE PLANNING
A number of local governments have found assessing
vulnerability across the broad range of government
services as an effective approach to anticipate, plan for,
and adapt to a changing climate. Boston provides a
useful example.
In the 1980's and 1990's, Boston planners and engineers
considered future sea level rise while overhauling the
city's Deer Island
Wastewater Treatment
Plant. To protect its
investment the city
raised the plant two
feet higher than
originally planned.
In 2007, the mayor directed each city department to
assess its vulnerabilities and risks to account for a
changing climate. Departments incorporated these
findings into municipal and community planning
projects, permitting, and review processes. In 2011,
Boston completed its first Climate Action Plan and in
2013 launched Climate Ready Boston to further advance
its efforts to anticipate and prepare for the changing
climate. Goals include adding climate preparedness to
public health programs that are already aimed at
vulnerable populations and expanding public outreach
to neighborhood groups. In 2015, Boston committed to
address climate impacts on a regional basis as part of the
Metro Mayors Coalition.
Boston's comprehensive approach increased awareness
and adaptive capacity, identified department-level risks
and potential actions, and leveraged the knowledge and
expertise of its departmental staff.
Climate Ready Boston identified several keys that it
believes may be helpful for others, including:
• Climate preparedness must be an important and explicit
criterion in the city's capital planning;
• Effects of rising temperatures should be a high priority;
• Municipal emergency plans should be reviewed and
practiced in light of expanded risks posed by climate
change;
• Close coordination with regional, commonwealth/
state, and federal partners is necessary to address
cross-jurisdictional infrastructure vulnerability; and
• Education, engagement, and communication — within
city government and with the broader community —
are essential for preparing for both the short-term and
long-term effects of climate change.
