Executive Summary
Executive Summary
Creating Disaster-Resilient Buildings to Minimize Disaster Debris provides practical actions for
communities (e.g., cities, counties, states, territories, and tribes) on planning, designing,
improving, and adapting new and existing buildings to withstand natural disasters. Community
leaders and members, planners, designers, builders, and disaster response experts can use
this information to increase the resiliency of homes, businesses, and other buildings to the
impacts of natural disaster hazards, including flooding, fire, and high winds.
Natural disasters and extreme weather events pose significant risk to human health and the
environment and burden communities, waste management facilities, and transporters. The
generated debris is often disposed of in landfills, even when it could be safely reused,
recycled, or composted - contributing to the circular economy. Designing the built
environment, such as buildings and roadways, to be resilient to disasters helps minimize
disaster debris and make reconstruction efforts less costly while using fewer resources.
Resilient communities generate significantly less debris during and after a natural disaster,
recover faster, encouraging residents and businesses to stay in the area as normal operations
resume sooner, and save money and use fewer resources to rebuild and recover.
The first part of this document highlights proven, innovative strategies for disaster-resilient
buildings. These best practices are inspired from nature and lived experience. They are
organized by what can be done before a disaster, in anticipation of an imminent disaster, and
after a disaster. Many of the practices apply to more than one phase. The second part
presents lessons learned from two natural disasters, which illustrate the need for resilient
buildings and strategies. The third and last part of the document provides resources on debris
management, disaster planning, and resiliency that explore these topics in more depth.
Creating disaster-resilient buildings presents an opportunity to minimize disaster debris while
advancing a circular economy, conserving resources, decreasing waste, and reducing health,
social, environmental, and economic impacts.

Creating Disaster-Resilient Buildings to Minimize Disaster Debris
Introduction
Introduction
Every year, natural disasters challenge the
built environment for communities in the
United States, destroying homes,
businesses, and other infrastructure and
costing billions of dollars in damages. With
the frequency and severity of natural
disasters, such as landslides, hurricanes,
tornadoes, wildfires, and intense storms
increasing, the impacts associated with
these disasters are growing and include loss
of life, community disruptions, environmental
impacts, property loss, and the burden of
dealing with disaster debris.
Disaster response and recovery also
increase the demands on energy, natural
resources, and community resources. By
taking action to mitigate risks before a natural disaster occurs, communities can reduce
community disruption and recovery costs after a disaster, advancing a circular economy. Some
of the actions that can help mitigate risks are designing resilient and adaptable buildings and
retrofitting existing buildings, securing the property against expected hazards, creating a
disaster debris management plan, and contacting relevant agencies and organizations.
What Is the Built Environment?
The built environment touches all aspects of
people's lives, encompassing the buildings
people live and work in, the distribution
systems that provide communities with water
and electricity, and the roads, bridges, and
transportation systems people use to get from
place to place.
Generally, the built environment
encompasses the human-made or modified
structures that provide people with living,
working, and recreational spaces. Creating all
these spaces and systems requires enormous
quantities of materials.

Introduction
What is a Circular Economy?
A circular economy keeps materials and products in circulation for as long possible. The
Save Our Seas 2.0 Act refers to an economy that uses a systems-focused approach and
involves industrial processes and economic activities that are restorative or regenerative by
design, enables resources used in such processes and activities to maintain their highest
value for as long as possible, and aims for the elimination of waste through the superior
design of materials, products, and systems.1
What is Embodied Carbon?
Also known as embodied greenhouse gas (GHG) emissions, embodied carbon refers to the
amount of GHG emissions associated with upstream—extraction, production, transport, and
manufacturing—stages of a product's life. Many initiatives to track, disclose, and reduce
embodied carbon emissions also consider emissions associated with the use of a product
and its disposal.2
Understanding and disclosing these emissions to better inform selection of lower-embodied
carbon construction materials and products is rapidly advancing and is critical to reducing
the carbon footprint of the built environment.
Decisions on design, construction, and materials within the built environment can have
significant impacts on carbon emissions, human health, and resiliency.
This document focuses on actions community officials, leaders, and members
(including those in cities, counties, states, territories, tribes, businesses, and
community organizations) can take to plan, design, improve, and adapt homes and
other buildings to withstand natural disasters. It advances a circular economy approach,
shifting from the model in which resources are mined, made into products, and then become
waste. A circular economy reduces material use, redesigns materials to be less resource and
carbon intensive, and recaptures "waste" as a resource to manufacture new materials and
products.

Introduction
What Is Natural Disaster Debris and Why Should We Care3?
Natural disaster debris refers to the material and waste streams resulting from a natural
disaster.
Disaster debris often includes building materials, sediments, vegetative debris, and personal
property. Large quantities of debris can make response and recovery efforts difficult by
hindering emergency personnel, damaging or blocking access to necessary infrastructure,
and posing threats to human health and the environment.
The needs for disaster debris mitigation and sustainable management of generated debris
are growing rapidly as the frequency and severity of natural disasters continues to increase.
For many communities, more and stronger disasters means larger quantities of debris will be
generated that may end up in landfills, thereby leaving the circular economy.
Considering the health, environmental, social, and economic costs and impacts to
communities associated with debris generation, cleanup, and management, the development
of effective strategies to plan for, mitigate, and respond to natural disaster debris is critical for
resilience. Resilience means the capacity to plan for, withstand, adapt to, and recover from
natural disasters with minimal damage in a timely, effective, and safe manner.
From 2011 to 2022, 90 percent of U.S. counties - covering over 300 million people -
experienced a flood, hurricane, wildfire, or other emergency serious enough to receive a
federal disaster declaration, and more than 700 counties suffered 5 or more such disasters.4
When considering all the health, environmental, social, and economic costs of managing
debris, including from damaged buildings, after a disaster, it is more sustainable and likely less
costly to invest in resilient building siting and design before a disaster happens. A community
that invests in debris mitigation actions before a natural disaster occurs can significantly
reduce the generation of natural disaster debris after a disaster; protect neighborhoods; save
energy, natural resources, and community resources; and, thereby, reduce response and
recovery costs.
For example, the National Institute of Building Sciences' Natural Hazard Mitigation Saves:
2019 Report documents that rebuilding to the most recent building codes requirements saves
on average $11 per $1 spent on mitigation, while exceeding building code minimum
requirements saves $4 per $1 spent (Figure 1 below).5 Additionally, FEMA's Building Codes
Save: A Nationwide Study estimates $132 billon could be saved in property losses based on
past and forecasted growth in the use of modern building codes from 2000-2040.6

To support the implementation of mitigation measures and practices that result in less disaster
debris generation and, therefore, reduce the cost of response and recovery, this document
provides an overview of:
1) Proven, innovative strategies for disaster-resilient buildings.
2) Lessons learned from natural disasters.
3) Resources on debris management and disaster planning.
Planners, designers, builders, disaster response experts, and community members can use
this information to improve communities' resilience to natural disasters. Resilience strategies
increase the ability of the community to withstand and recover from natural disasters and
related impacts. Incorporating these strategies together into building designs and
improvements creates strong buildings and communities that can:
• Generate significantly less debris during and after a natural disaster.
• Recover faster, encouraging residents and businesses to stay in the area.
• Save money and use fewer resources to rebuild and recover
Impacts of Natural Disaster Hazards on Buildings
Hazards from flooding, wind, fire, and other natural disasters vary widely and may cause a
broad range of building-related damage and debris, especially if buildings have not been
designed or retrofitted to withstand worsening hazards. Communities may be at risk for more
than one type of natural disaster and may experience several disasters together. Their hazards
can impact buildings and communities.

Creating Disaster-Resilient Buildings to Minimize Disaster Debris
Introduction
Adaptation and resilience strategies are inherently place-based and should start with an
understanding of which natural disasters a particular community is likely to experience and the
impacts these hazards may have in the specific area. Historical and geographical information
can help a community understand and prioritize planning for specific types of disasters and
their hazards.
Also, the characteristics and features of the location and surrounding area may exacerbate
hazards from natural disasters. For example, buildings in floodplains face a greater risk of
flooding, and buildings located on slopes may face a greater risk of erosion or landslides.
Existing structures can often be retrofitted to better address current and future hazards. New
structures should be designed and built to withstand all expected hazards now and in the
future. Communities should also keep in mind that reducing development in high-risk areas like
coastal areas projected to be impacted flooding and changing floodplain areas7 may be the
best strategy for avoiding additional damage from natural disasters.

floodplain definitions. FEMA. (2023). Federal Flood Risk Management Standard.

Section 1. Best Practices for Creating Resilient and Adaptable
Buildings
Resilient building adaptation and strategies range from simple and inexpensive to complex and
costly. Some strategies can be implemented before any natural disaster occurs, in anticipation
of an impending natural disaster, and after a natural disaster is experienced to build back a
stronger and more resilient community.
This section describes some of the best practices that communities can take to protect the built
environment from natural disasters. Because the EPA encourages integrated, place-based
planning and design appropriate for building function and local conditions, the
following strategies and materials are not appropriate for all types of disasters,
locations, and building types.
1.1. Before Natural Disasters
When anticipating future natural disasters, using best practices in building design can support
building and infrastructure resilience. Resilient building design can leverage natural systems
and protections and incorporate biomimicry - the practice that learns from and mimics the
strategies found in nature to solve human design challenges. In addition to designing for
resiliency, other strategies to consider include designing buildings for disassembly and
adaptation. Existing buildings can be retrofitted and upgraded to be resilient and adaptable to
help limit damage from natural disasters and extreme weather events, decrease the amount of
debris generated by disasters, and speed up recovery. Current building codes and standards
can help guide building design and retrofits.
Enhancing the resilience and adaptability of new and existing buildings can also help reduce
the exposure of communities to disasters. For example, these best practices can advance
accessible housing and infrastructure services by reducing destruction and recovery costs.
Circular design principles can promote the use of renewable, biodegradable, and locally
sourced materials, which can reduce greenhouse gas emissions, waste generation, and
resource depletion. Also, by encouraging the reuse and recycling of building materials and
components, the need for new extraction and production is reduced, which lowers the costs
and environmental impacts of recovery. These best practices can also support the continuity
and reliability of essential services, such as energy, water, and waste management.
Plans should be made to identify any need for services to those with disabilities and limited
English proficiency (LEP) to provide meaningful access to services.

1.1.1. Design for Resilience
Below are some strategies and resources to consider when designing buildings for resilience.
Passive Survivability
Resilient design can also include planning for passive survivability, or designing a building
to provide necessary shelter, thermal, and other life-support services during extended utility
service disruptions. Designing for passive survivability can protect building occupants and
help prevent additional damage and building-related disaster debris. For example, a tight
building envelope and plumbing that will not freeze can reduce disaster debris from flooding.
Passive survivability is especially important for critical infrastructure, such as fire and police
stations, hospitals, schools, and emergency shelters.
Natural Systems
Considering natural systems and using natural materials during building design is a growing
source of innovation used to generate more resilient buildings. Below are some examples of
leveraging natural systems to help protect buildings and surrounding infrastructure from
potential natural disasters.

Biomimicry
Blomimicry, an emerging set of practices that uses nature as both a pattern and an inspiration,
can allow for more resilient and regenerative designs. This creative approach holds promise
for reducing building-related disaster debris. Biomimicry can also inform the positioning and
relationship of buildings to each other and to the local environment. EPA acknowledges the
leadership of the Biomimicry Institute and Biomimicry 3.8 in developing and sharing this
inspiring approach to designing buildings and building materials.8

insights for building disaster resilient

Increasing Building Resiliency: Root Systems
The oak trees that survived Hurricane Katrina could be
used as a case study for surviving hurricanes.
Underground, their roots are intertwined with
neighboring trees, so when hurricane-force winds hit,
the interconnected root systems mean the trees are
more likely to remain standing than if their roots were
not interconnected.
Research could be conducted to understand if building
foundations could be connected with intertwined
horizontal components to better withstand high wind
speeds. Similarly, the intertwining of roots of mangroves
on vulnerable coastal slopes and areas subject to
erosion could inspire research tying building foundation
systems together to increase strength and stability.

Increasing Building Resiliency: Velcro and Webs
Velcro is another example of design informed by nature.
It was invented by a Swiss engineer after he examined
the tiny hooks of cockleburs stuck on his pants and in
his dog's fur. Using a similar hook-and-loop fastening
system, Velcro could be used to inform new
construction of exterior building systems (e.g., panels)
that could be reused, adjusted, and repositioned to
adapt to changing environments.
The web silk of spiders is both lightweight and extremely
strong - in some cases, stronger than steel. It is a
remarkable example of biomaterial with superior
mechanical characteristics. Engineers are looking into

By combining structural system design and biology,
engineers are investigating the growth patterns of
bamboo, the fractal geometry of the chambered

how to design more resilient high-rise structures using
fewer materials while increasing structural integrity.
Inspired by nature and the structural durability of
natural forms like shells, some dome-shaped buildings
can withstand high winds and debris impacts from
hurricanes and tornadoes, as well as earthquakes.
Efficient structural forms mimicking those found in
nature can reduce the overall volume of materials
required and eliminate large quantities of waste.

Resources on Resilience
Place-based pre-disaster preparation and disaster resilience planning that incorporates
integrated hazard planning (e.g., source reduction; hazard mitigation; increased reuse,
recycling, and composting), including mapping and assessment of both hazards and
resources, can increase disaster resilience. Boosting community resiliency in anticipation and
preparation for a natural disaster leads to a quicker and less costly recovery to the pre-incident
state after a disaster occurs. The box below highlights some key disaster resiliency planning
resources that can help communities develop strategies to decrease potential debris before a
disaster occurs.

Section 1
1.1.2. Design for Disassembly and Adaptation
Below are some strategies and resources to consider when designing buildings for
disassembly and adaptation. This type of design is also sometimes called circular or reversible
design.
Disassembly
Designing for disassembly—buildings with systems and materials that are easy and safe to
take apart, repair, and reuse—is an important consideration of the complete life cycle of a
structure. Disassembly supports the reuse and repair of buildings and building components.
Designing buildings for easy disassembly can also reduce disaster-related building debris and
support the repair, reuse, recycling, and even the relocation of structures and materials after
disaster events. Items that can often be safely reused include:
Lumber (structural and non-
structural)
Wood flooring
Trim
Cabinets & Vanities
Brick
Pavers
Roofing Tiles
Doors
Fireplace mantels
Countertops
*Windows
*Fixtures
*Appliances
'Reuse if they meet code or recycle.
Benefits of design for disassembly and building adaptation include reducing a building's life
cycle environmental impacts, minimizing waste, reducing costs, and supporting the local
economy and jobs.
Figure 13, The South Lake Union Discovery Center in Seattle was designed for future transportation,
reassembly, and reuse in a new location. The building separates at three integrated joints to break into four
modules that can be moved on trucks by streets (not freeways). The building sits lightly on the land atop short
concrete piers, allowing the grade and vegetation to run uninterrupted beneath. Gangway ramps with hinged
joints can adapt to the topography of future locations (The Miller Hull Partnership).

Creating Disaster-Resilient Buildings to Minimize Disaster Debris
Section 1
Ten Key Principles for Design for Disassembly
1. Document materials and methods for
deconstruction. As-built drawings, labeling
of connections and materials, and a
deconstruction plan in the design
specifications all contribute to efficient
disassembly and deconstruction.
2. Select materials using the
precautionary principle. High-quality
materials that are chosen with consideration
for future impacts will retain value and/or be
more feasible for reuse and recycling.
3. Design connections that are accessible.
Visually, physically, and ergonomically
accessible connections will increase
efficiency and avoid requirements for
expensive equipment or extensive
environmental health and safety protections
for workers.
4. Minimize or eliminate chemical
connections. Binders, sealers, and glues on
or in materials make them difficult to separate
and recycle, as well as increase the potential
for negative human and ecological health
impacts from their use.
5. Use bolted, screwed, and nailed
connections. Using standard and limited
palettes of connectors will decrease tool
needs, as well as time and effort to switch
between tools.
6. Separate mechanical, electrical, and
plumbing systems. Disentangling these
systems from the assemblies that host
them makes it easier to separate
components and materials for repair,
replacement, reuse, and recycling.
7. Design to the worker and labor of
separation. Creating human-scale
components or making components easy
to remove by standard mechanical
equipment will decrease labor intensity
and increase the ability to incorporate a
variety of skill levels.
8. Simplicity of structure and form.
Simple open-span structural systems
and forms, as well as standard
dimensional grids, will allow for ease of
construction and deconstruction in
increments.
9. Interchangeability. Using materials
and systems that exhibit principles of
modularity, independence, and
standardization will facilitate reuse.
10. Safe deconstruction. Allowing for
movement and safety of workers,
equipment and site access, and ease of
materials flow will make renovation and
disassembly more economical and
reduce risk.

Adaptation
Designing buildings to adapt to increasingly frequent and intense disasters can help reduce
debris and their impacts post-disaster.

Indigenous Resilient Design
Examples of adaptable infrastructure can be found in Indigenous communities. The survival
of many cultural traditions, including those practiced by Tribes and Indigenous nations,
depend on safe access to raw materials found in nature. Because cultural traditions relied on
the availability of natural resources, many tribal societies focused on developing building
designs and practices that would endure for future generations. Traditionally, tribal nations
built structures using local resources, without benefit of written codes or modern machinery.
These structures were safe, strong, and energy and water efficient. Indigenous Resilient
Design provides a framework for how communities can create infrastructure that is
adaptable, ecofriendly, and enduring.
The National Institute of Health's Environmental Health Perspectives article entitled,
"Healthier Tribal Housing: Combining the Best of Old and New," provides an overview of the
environmental and health benefits of modern adaptations of indigenous building materials
and designs. The article explains the use and reuse of locally sourced materials and green
design elements to build homes that can adapt and respond to local weather.9
For example, earth lodges were a common form of shelter built by American Indians,
particularly by the Great Plains and Eastern Woodlands tribes. These underground or semi-
underground shelters, partially or completely covered with earth, were usually circular or
elongated round structures with a dome-like roof. They provided excellent shelter from high
winds and extreme temperatures.10
Other Examples of American Indian Resilient Design
The Sustainable Native Communities Collaborative, with funding from the U.S. Department
of Housing and Urban Development (HUD), produced case studies of traditional and local
materials used in tribal building projects:
• Navajo Nation Elder Hogan Homes combined traditional design with low-tech, tribally
sourced materials, including straw bales from the Navajo Agricultural Products
Industry, FlexCrete (Navajo-owned, lightweight, energy-efficient aerated concrete
panels), and other high-performance materials for durable, low-impact, culturally
accurate housing.11

• The Ohkay Owingeh Owe'neh Bupingeh project in the northern New Mexico pueblo of
Ohkay Owingeh was a culturally accurate housing rehabilitation program that included
research into traditional materials and techniques, education and training, sourcing of
local materials, and restoration of adobe housing in the village that has been occupied
for at least 700 years. The work included using earthen plasters, restoring traditional
roof vigas (round wood beams), and reusing the materials from unstable adobe walls
that were torn down and replaced in the earthen plaster. The project also included
energy upgrades, such as insulation and better windows.13
• The Pinoleville Pomo Nation Homes project near Ukiah, California built two earthen-
plastered straw bale homes designed through a collaborative community design-build
process with technical assistance from the University of California, Berkeley. The
homes incorporate culturally accurate design features, natural finishes, locally
harvested timbers, and energy and water efficient design.14

buildings to improve their resilience to different natural hazards and disasters, as well as
example funding strategies and incentives.

Creating Disaster-Resilient Buildings to Minimize Disaster Debris
Section 1
Storm and High Wind Event Preparedness
Doors and Windows
• Install temporary or permanent storm doors
and impact resistant windows and shutters
ahead of a high-wind event.
• Ensure external doors and windows open
outward to resist being blown open in high
winds. When doors or windows blow open and
allow rain into buildings, increased interior
pressure can contribute to roof and wall failures
and cause mold issues.
Walls, Roofs, Garage Doors, and Gutters
• Install lateral bracing to reinforce gable end
walls (i.e., the triangular portion of a wall
between the edges of intersecting roof pitches).
Gable end wall failure is one of the most
common types of damage caused by
hurricanes (Figure 16).
• Strengthen roof-to-wall connections by using
a combination of straps to transfer uplift from
the trusses or rafters through the double top
plate and into the wail studs. This technique
can help tie the roof to the foundation and
support high-wind structural integrity.
• Install secondary water barriers with a water-
resistant layer or a roof underlayment layer or
product on the roof deck under the roofing to
protect against water intrusion and associated
moisture or mold damage.
• Install additional bracing systems (e.g.,
heavy-duty hinges and bars) on the inside of a
garage door to reinforce it from high winds.
• Design gutters to resist wind upload by
ensuring the roof edge flashing does not extend
into the gutter, lift up due to high winds, or peel
off the roofing and roofing membrane.
• Use appropriate fastener size, spacing, and
type for wall cladding, roofing, vents, IHVAC
equipment, windows, and doors. Decisions
should be governed by code requirements,
design wind speeds, and wind pressure
variation considerations.
Figure 16. Top: Gable end wall failure occurs
when walls lose support along the top edge; as
a result, sheathing is blown off, causing the
walls to fall inward or outward (South Carolina

Flood Preparedness
Design for Water
• Build with materials that can get wet and
easily dry, like concrete, brick, and ceramic
tile.
• Design basement or lowest floor walls in
flood hazard areas with breakaway walls,
openings, or automatic vents. These
features allow equalization of water levels
and pressures on walls and foundations,
preventing structural damage from floodwater
flowing under the building.
Protect Utilities
• Raise HVAC and electrical systems above
anticipated flood levels or protect them
from floodwater. Elevating equipment can
decrease equipment damage, the time and
cost needed to re-start the systems, and
building damage caused by extreme
temperatures or a lack of ventilation after an
event.
• Install backflow prevention valves for
sanitary sewer lines and floor drains.
Flood Barriers
• Add flood barriers, such as bottom tracks or
floor barriers to door and window frames and
other vulnerable openings, to ensure a
weathertight seal. Residential flood barriers
include systems to seal entry and garage
doors, crawlspace vents, basement windows,
and exterior stairs.

Fire Preparedness
Roofing and Attic Vents
• Install Class A roofing (i.e., highest resistance
to fire) and fire-resistant building materials. Plug
gaps, such as gaps that occur in some clay or
cement tile roofs at the ridge and at the lower roof
edge, with a non-combustible material.
• Avoid or retrofit roof vents and gutters to
reduce fire risk. Vents can allow embers and
high heat to enter roofs and eaves. All external
vents should be screened with 1/8-inch or 1/16-
inch metal mesh.
Gutters
• Cover roof gutters with screens or other devices
to keep debris, including flammable debris and
embers, from accumulating. Remove debris that
does accumulate.
• Install flashing (i.e., thin, impervious sheets of
material placed in construction to prevent water
penetration or direct the flow of water) that fully
covers the edge of the roof sheathing (i.e., sheet
or board material, such as plywood or particle
board, connected to the roof rafters to act as a
base for shingles or other roof coverings) and
flammable fascia (i.e., board or band at the
outside vertical surface of a building) near gutters.
Windows
• Install fire-resistant windows and shutters.
Dual-pane windows, with at least one pane of
tempered glass, offer greater fire protection.
Shutters or window covers of plywood can be
installed when needed and can also protect
windows from external fire heat.
External surfaces
• Choose non-combustible exterior walls.
Masonry, cement stucco, and fiber-cement siding
are examples of good exterior wall finishes in fire-
prone areas.
• Ensure deck surfaces adjacent to or
connected to buildings are ignition-resistant,
such as lightweight concrete.
• Choose non-combustible fencing products in
wiidfire prone areas.

Earthquake Preparedness
Note: Seismic structural upgrades typically require
engineering assessment and vary greatly between
sites and buildings.
Structural and Nonstructural Features
• Strengthen unreinforced masonry and
loadbearing walls, such as by using galvanized
steel wire ladder or truss laid in the mortar
between courses of brick or block.
• Strengthen foundation-to-wall and wall-to-roof
connections (more information in the section
above on Storm and High-Wind Event
Preparedness).
• Strengthen cripple walls, which enclose the
crawl space under the first floor in older wood-
framed buildings. Anchor plywood to the interior
face of the cripple wall, as well as to the sill plate
below the foundation, to increase wall strength.
• Add shear walls (i.e., braced panels) or steel
frames to strengthen multistory buildings.
• Install engineered tie-down systems for
manufactured housing.
• Add seismic restraints to heavy mechanical
equipment, water heaters, and appliances.

Creating Disaster-Resilient Buildings to Minimize Disaster Debris
Section 1
1.1.4. Building Codes and Standards
Building codes and standards establish a basic set of minimum requirements for performance
and safety of buildings and facilities. Although codes generally address specific types of
hazards, their focus has historically been on life safety, rather than sustainability or resilience.
In some cases, and especially due to extreme weather, resilience planning is essential to
ensure safety and protect life.
The International Code Council (ICC) develops the most widely used model building codes
throughout the United States. Chapter 3 of the ICC Performance Code for Buildings and
Facilities provides "a framework to establish minimum levels to which buildings or facilities
should perform when subjected to events such as fires and natural hazards." The minimum
levels established by this chapter are based on the risks associated with "the use of the
building or facility, the intended function of the building or facility and the importance of the
building or facility to a community."
ICC recommends higher building standards for buildings with potentially large occupancies,
such as schools; power, water, and wastewater facilities; buildings containing significant
quantities of hazardous materials; and hospitals, health care, and emergency care facilities.
These codes can be applied to other types of buildings, including residential buildings, to
provide more resilient performance in disasters.18 Other code resources include:
• The International Green Construction Code, which contains provisions for more
sustainable and resilient commercial buildings.19
• State of Georgia's Construction Codes include two "permissive" code appendices ("R"
and "N") for residential and commercial disaster resilient construction, respectively.
These Disaster Resilient Building Code Appendices are optional regulations relating to
hurricane, flood, and tornado damage and disasters.20
• Oregon's 2017 Residential Specialty Code allows the reuse of residential framing
lumber that is not damaged or cracked, which can reduce waste and support post-
disaster rebuilding efforts.21
Building codes and guidelines can advance disaster resilient building practices. State and local
governments in regions with more severe and/or more frequent hazard events sometimes
enact stricter requirements than model building codes. One example is more stringent
earthquake requirements in California.

Creating Disaster-Resilient Buildings to Minimize Disaster Debris
Section 1
Other disaster-specific examples include:
• Flooding and High Winds. The state of Georgia has a Permissive Disaster Resilient
Building Code. Provisions, which local jurisdictions must adopt to enforce them,
promote enhanced public health, safety, and general welfare in order to reduce public
and private property losses due to hazards and natural disasters associated with
flooding, high winds, and windborne debris.
• High Winds. The city of Moore, Oklahoma, has building codes for wind resistance.22
Following a devastating tornado outbreak in 2013, the city of Moore modified their
building codes to incorporate more stringent building practices for homes to be built to
withstand winds of 135 miles per hour (mph). The new research-based code provisions
address roof sheathing and nailing, maximum 16-inch spacing for roof and exterior wall
framing, hurricane clips or framing anchors on all roof framing connections, structural
sheathing and bracing for gable end walls, continuous plywood bracing, wind-resistant
garage doors, and other requirements.
• Tsunamis. The 2015 and 2018 editions of the International Building Code (IBC)
Appendix M Tsunami-Generated Flood Hazard provisions23 make tsunamis a required
consideration in planning, siting, and design of coastal structures in the five western
states subject to tsunamis.
• Hurricanes. After the devastating impacts from Hurricane Andrew in 1992, the state of
Florida established some of the most stringent storm-specific building codes in the
United States. Miami-Dade County adopted the new building codes, which includes
product approvals for construction materials, an updated safety inspection program, and
trainings.24
• Performance-Based Codes. Innovative performance-based codes, such as those
referenced in the National Institute of Building Sciences High Performance Building
Council's National Performance Based Design Guide, can support resilient design and
construction of new facilities and major repairs and alterations of existing buildings.25

1.3. After Natural Disasters
After a natural disaster, communities may need to manage disaster debris from any damaged
buildings and repair and rebuild. Planning can facilitate the management of debris and post-
disaster rebuilding and should begin as soon as possible, even before a natural disaster
occurs, if possible.31 EPA developed an online All Hazards Waste Management Planning Tool,
available at https://wasteplan.epa.gov/welcome. to help communities create or update a
comprehensive disaster debris management plan for managing materials and wastes
generated from disasters. Rebuilding in the recovery phase after a disaster is an opportunity to
make the community more resilient for the next disaster.
To further support a circular economy, rebuilding efforts can potentially incorporate building
materials recovered following the disaster to repair or rebuild structures. Coordinating and
collaborating with interested parties ahead of disasters is essential to support planning and the
safe reuse and recycling of building materials during response and recovery. In addition to the
communities themselves, these interested parties include disaster planners, emergency
responders, recovery experts, community organization members, builders, building officials,
and solid and hazardous waste professionals, such as deconstruction, reuse, recycling,
composting, and state and local solid waste departments and environmental agencies.
1.3.1. Planning for Resilience and Waste Reduction
Through planning, communities can determine how they can rebuild more resiliently and
sustainably after a disaster. Planning efforts should include the best practices and strategies
discussed in Section 1.1. for new and existing buildings and should incorporate lessons
learned in past events. Planning efforts should also include plans to implement resilient
building codes and standards in order to generate less debris from natural disasters in the
future.
Waste Reduction at Disaster
Response Camps
Planning for waste reduction is
critical when anticipating natural
disasters. An example where
post-disaster recovery planning
occurs is at disaster response
camps, which are temporary
command posts where
emergency responders and
firefighters coordinate initial
emergency response and
firefighting activities, spend their
off time, eat, and sleep. They are

typically self-contained mini-cities
that are set up in less than a day.
The U.S. Department of Agriculture (USDA) Forest Service National Greening Fire Team
(GFT), winner of an EPA Federal Green Challenge Innovation award, established a vision of
achieving net zero waste, water, and energy at all large fire incidents by 2030 and a mission
of integrating sustainable operations best management practices into the fire community.
USDA has also issued guidance to reduce overall use of financial and natural resources
without compromising safety or impeding incident operations.
The GFT team researched, recommended, and assisted with implementing sustainability
best management practices in incident operations in addition to:
• Releasing a "Sustainable Operations in Incident Management—Preparing for the 2019
Fire Season" memo for senior leadership.
• Establishing a public-facing website, quarterly bulletin, webinar series, and Ambassador
Program to increase awareness of GFT's mission and to advance application of its
deliverables.
• Executing an Onsite Incident Recycling Blanket Purchase Agreement (BPA) - or
contract -spanning four Geographic Area Coordination Centers covering Arizona, New
Mexico, California, Oregon, and Washington.
Figure 22. Recycling station at a U.S. Forest Service fire camp.
The three-year BPA was ordered on nine fires in 2019 to:
• Standardize recycling equipment, signs, processes, and expectations so fire camp
personnel have a similar recycling experience on each camp, increasing efficacy and
engagement.
• Assure incident management teams that waste diversion services at fire camps would
improve waste management practices with less strain on in-house personnel.
• Standardize waste diversion reporting to capture and communicate waste reduction and
recycling results to achieve compliance with waste reduction directives, executive orders,
and laws.
The BPA has cut waste hauling costs by 50 to 80 percent, with a cost savings of up to
$18,000 per week, while conserving resources and reducing local community landfill
impacts.

Creating Disaster-Resilient Buildings to Minimize Disaster Debris
Section 1
Specific fire camp zero waste recommendations included:
• Use bulk water whenever possible. Bottled water costs more money and depletes
resources.
• Recycle as much as possible while at fire camp.
• Reduce food waste.
• Avoid unnecessary vehicle idling in fire camps, which creates unnecessary pollution.
Firefighters take precautions to protect their lungs on the fire line; the same should be
done where they sleep and eat.
For debris that is generated, debris management plans should document how debris will be
safely and sustainably managed and waste will be reduced. These plans should also cover
activities, such as:
• Collection, temporary storage, and safe management of household and other
hazardous waste and waste with hazardous or harmful components, potentially
including electronics.
• Segregation of materials for safe reuse and recycling, including concrete and
asphalt recycling, and mulching or composting of clean unpainted lumber and
vegetative debris.
• Tracking and the documentation of debris managed in different ways, including
through reuse, recycling, mulching, composting and disposal, as well as
quantities, revenues, and costs.
• Planning and contracting with local or regional haulers, equipment operators,
recyclers, and other contractors capable of storing, collecting, transporting, and
processing disaster debris.
• Collection of information on key contacts and established networks of disaster
experts, training professionals, and community organizations.
• Certification procedures and documentation for qualified disaster recovery
personnel.
To effectively adapt strategies over time, a disaster recovery phase review and assessment
should be included in the planning process. This will support continuous learning and
communicating lessons learned with other communities and interested parties.
1.3.2. Using Salvaged Materials
A circular economy is supported by buildings that are not only designed for disassembly and
adaptation, but also by buildings that can be converted into stocks of materials or "material
banks" of resources for rebuilding, repairs, and upgrades. Using building materials recovered
following a disaster to repair or rebuild structures or to build disaster response sheds to

Creating Disaster-Resilient Buildings to Minimize Disaster Debris
Section 1
Opportunities to advance large-scale building reuse are growing as communities, such as
Portland, Oregon33 and Palo Alto, California,34 adopt successful mandatory deconstruction
policies, and communities work to find the highest and best use of materials and keep organic
material, including wood, out of landfills. GSA's Federal Center South project that used nearly
200,000 board feet of structural and nonstructural iumber from an adjacent warehouse is a
great example of reuse at scale. Some green building rating systems have also incorporated
credits related to design for deconstruction, adaptation, and flexibility.35
securely store response workers' belongings and supplies can reduce both environmental
impacts and costs of rebuilding. For example, clean, undamaged lumber can be reused, and
damaged concrete can be used as base, such as crushed aggregate material, in accordance
with all applicable codes and regulations. This reduces the environmental impacts of building
material production, transportation, and disposal, as well as the need to buy new lumber or
base material. This approach reduces waste and the embodied carbon emissions to
manufacture and transport building materials.
When entire structures cannot be rebuilt, opportunities to deconstruct and salvage building
materials exist. For example, in Alachua County, Florida, a home located in a floodplain was
deconstructed as part of a FEMA-funded buyout and the lumber was used to rebuild HUD
Section 8 affordable housing inland using current building codes.32

Extreme weather hazards, such as flooding, will put many buildings that have not yet been
damaged in harm's way. Investing in planning, infrastructure, and policies to reclaim those
buildings and their valuable materials to rebuild inland is a circular economy opportunity that
can both reduce the need for new materials and provide local construction jobs and job
training.36
After disasters such as hurricanes Katrina and Irene, organizations, including Mercy Corps and
the Building Goodness Foundation, safely deconstructed homes to rebuild, repair, and develop
disaster recovery sheds.37 An important outcome for those impacted by the disaster: they
received deconstruction job training, meaningful work, and income, as well as overall help with
disaster recovery.38

Section 2. Lessons Learned from Natural Disasters
Lessons learned from community experiences in responding to natural disasters, such as
using existing resources, debris segregation, and clear and consistent communication, have all
proven to be essential practices in making debris prevention and management as efficient as
possible. More information on best management practices based on past disasters is found in
EPA's Planning for Natural Disaster Debris guide (https://www.epa.gov/homeland-securitv-
waste/guidance-about-planning-natural-disaster-debris). Below are some examples of lessons
learned from natural disasters and recommendations for creating more adaptable and resilient
buildings and infrastructure.
2.1. Extreme Coastal Storm Events
There has been a substantial increase in the severity and frequency of hurricane and typhoon
activity in the Atlantic since the 1980s, and there are more catastrophic typhoons and
hurricanes in the Pacific Islands area, including the U.S. territories of Guam, American Samoa,
and the Commonwealth of the Northern Mariana Islands, than in any other place on earth.
Increases in the severity and frequency of these storm events will affect buildings and increase
exposure and vulnerability, thereby increasing the impacts of these disaster events. Increased
debris quantities will be challenging to manage, and damage to buildings and infrastructure will
be costly to repair, particularly in rural areas. Without resilient and adaptive building strategies,
the negative impacts and costs will continue to rise.
Disaster Example: Typhoon Soudelor,
Saipan, Commonwealth of the Northern
Mariana Islands
In the summer of 2015, Typhoon
Soudelor hit Saipan, an island in the
Commonwealth of the Northern Mariana
Islands with a population of
approximately 48,000 people. It was the
strongest typhoon of the 2015 Pacific
typhoon season, and it caused severe
damage and 40 fatalities in the Pacific
Islands and Asia. The Category 5 storm
had sustained winds of 130 mph and
gusts of more than 160 mph.39
An assessment found that Typhoon
Soudelor impacted over 1100 homes. Of
this total, almost 600 were completely destroyed or had sustained major damage. About 600

people sought shelter due to damaged homes.40 On Saipari, all of the homes destroyed or
damaged had been constructed using outdated building codes.
In the first few weeks after the storm, almost
no municipal power or drinking water were
available to island residents, and it took
nearly three months for residents to regain
basic services. The typhoon destroyed
approximately half the island's primary power
distribution system. In addition, the island's
power plant lost part of its roof and was
flooded. The storm also knocked down many
trees and 188 utility poles, which damaged
733 transformers and made many roads
impassable.
The local power company, Commonwealth Utilities Corporation, had only 77 replacement
power poles and no replacement transformers. Repairs to the electric grid, water supply
network, and wastewater systems took months.
The U.S. Army Corps of Engineers, EPA, the
government of Guam, the Guam Power
Authority, and other entities provided
emergency supplies and restored services.
EPA led efforts to safely reuse, recycle,
mulch, and dispose of the disaster debris
generated.

2.2. Wildfire arid Fire Events
Changes in temperature, precipitation, wind patterns, and other phenomena are causing
extreme wildfire events that are creating new risks to communities. More intense droughts and
warmer temperatures cause larger wildfires and longer fire seasons, and they generate even
larger amounts of debris. For example, heavy rainfall in an area devastated by wildfires can
increase the possibility of massive mudslides due to destroyed vegetation on slopes.
Disaster Example: Wildfires in California

million structures, or roughly one out of every ten buildings in California, lie within the highest
risk fire zones in maps drawn by CAL FIRE.
The combination of dry and windy weather, continuous fuels, and proximity to residential
development creates a strong potential for wildfires to burn homes. In 2017, CAL FIRE listed
more than 5,700 residential properties in California as total losses due to wildfires and over
15,000 residential properties as partial losses. Specifically, the Tubbs Fire claimed 22 lives,
charred over 36,000 acres in the state's wine country, and destroyed 5,643 structures in
Northern California's Sonoma and Napa counties. In November of 2018, the Camp Fire in
Butte County burned over 153,336 acres, destroying over 18,800 structures and claiming 85
lives, making this the deadliest and most destructive fire in California history.44 In August 2020,
the August Complex fire (which originated as 38 separate fires started by lightning strikes)
became the largest wildfire in California's recorded history, burning over 1,032,648 acres in the
coastal range of Northern California.45 The Dixie Fire in July 2021 became the largest single

Conclusion
Conclusion
The need for effective natural and sustainable disaster debris management is growing rapidly
as the frequency and intensity of disasters continue to increase. Considering the cost and
community impacts associated with response and recovery, developing effective strategies to
plan for, mitigate, and respond to natural disaster debris is critical to helping all communities
become more resilient. Incorporating resilient building design and best practices are important
strategies for mitigating disaster debris, creating resilient communities, and advancing a
circular economy.
Every step of building planning, design, retrofit, and post-disaster deconstruction and
reconstruction presents opportunities to revisit building practices and embrace new
approaches, such as designing for increased resiliency and increasing safe reuse, recycling,
and composting to reduce waste and embodied carbon.
Communities can adapt the strategies and best practices in this document to each disaster
event they experience now and in the future. Planning for disasters is critical to minimizing
disruption to a community, conserving resources, and generating less disaster debris. In
addition, planning for and developing healthy, disaster resilient buildings can reduce waste and
conserve valuable resources over the life cycle of a built environment—including the post-
disaster response and rebuilding phases—to protect the health of building occupants and
disaster responders.
Creating disaster-resilient buildings can have positive impacts by enhancing the resilience of
communities to natural disasters and by promoting their agency in the circular transition.
EPA is interested in learning about your resilient building experiences and recommendations.

Glossary
Glossary
Biomimicry: A practice that learns from and mimics the strategies found in nature to solve
human design challenges. (Biomimicry Institute)
Circular economy: An economy that uses a systems-focused approach and involves
industrial processes and economic activities that are restorative or regenerative by design,
enables resources used in such processes and activities to maintain their highest value for as
long as possible, and aims for the elimination of waste through the superior design of
materials, products, and systems (including business models). (Save Our Seas Act 2.0)
Debris: The material and waste streams resulting from a natural disaster that often includes
building materials, sediments, vegetative debris, personal property, and other materials.
Deconstruction: The selective dismantlement or removal of materials from buildings for
primarily reuse or, secondarily, recycling.
Embodied carbon: Refers to the amount of greenhouse gas (GHG) emissions associated
with upstream—extraction, production, transport, and manufacturing—stages of a product's
life. Many initiatives to track, disclose, and reduce embodied carbon emissions also consider
emissions associated with the use of a product and its disposal. It is also known as embodied
GHG emissions.
Passive Survivability: The ability of a building to provide necessary shelter, thermal, and
other life-support services during extended utility service disruptions.
Resilience: The capacity to plan for, withstand, adapt to, and recover from natural disasters
with minimal damage in a timely, effective, and safe manner.
Resilient communities: Communities that are resilient recover faster, contain fewer harmful
materials, generate less debris, and need fewer resources to rebuild.
Retrofit: A way to adapt to evolving hazards and a tool for disaster risk reduction by making
changes to existing structures to mitigate the impacts of natural hazards.
Reuse: The utilization of a product or material that was previously installed for the same or
similar function to extend its life cycle.
