Preparedness is the shared responsibility of all levels of
government, the private and nonprofit sectors, and individual
citizens. Individuals and households are at the core of our
Nation's preparedness. A community's ability to respond to or
recover from a disaster depends on the level of preparedness of
every member. However, a 2009 Citizen Corps National Survey found
that 29 percent of Americans have not prepared because they think
that emergency responders will help them and that over 60 percent
expect to rely on emergency responders in the first 72 hours
following a disaster. The reality is that in a complex disaster,
first responders and emergency workers may not be able to reach
everyone right away. In addition, providers may not be able to
restore critical services, such as power, immediately. The purpose
of this initiative is to promote personal and community
preparedness through engaging activities for individuals,
neighbors, or households. These activities are a set of building
blocks. You can mix and match the activities based on the needs of
your target audience or time available. Most activities can be
completed during a 15-minute to 60-minute session. You should adapt
the materials to include critical local information, such as
information on local hazards, local alerts and warnings, and local
community response resources and protocols. Remember, preparedness
does not have to be complex or overly time consuming. Rather, it
should motivate, empower, and engage the whole community.
Fire departments in the United States responded to nearly 1.6
million fire calls in 2007. The United States fire problem, on a
per capita basis, is one of the worst in the industrial world.
Thousands of Americans die each year, tens of thousands of people
are injured, and property losses reach billions of dollars. There
are huge indirect costs of fire as well-temporary lodging, lost
business, medical expenses, psychological damage, and others. These
indirect costs may be as much as 8- to 10-times higher than the
direct costs of fire. To put this in context, the annual losses
from floods, hurricanes, tornadoes, earthquakes, and other natural
disasters combined in the United States average just a fraction of
those from fires. The public, the media, and local governments
generally are unaware of the magnitude and seriousness of the fire
problem to individuals and their families, to communities, and to
the Nation. The National Fire Data Center (NFDC) of the U.S. Fire
Administration (USFA) periodically publishes Fire in the United
States, a statistical overview of the fires in the United States
with the focus on the latest year in which data were available at
the time of preparation. This report is designed to equip the fire
service and others with information that motivates corrective
action, sets priorities, targets specific fire programs, serves as
a model for State and local analyses of fire data, and provides a
baseline for evaluating programs. This Fifteenth Edition covers the
5-year period of 2003 to 2007 with a primary focus on 2007. Only
native National Fire Incident Reporting System (NFIRS) 5.0 data are
used for NFIRS-based analyses. In 2007, the native NFIRS 5.0 data
account for 98 percent of the fire incident data. The report
addresses the overall national fire problem.
Past storms such as Hurricanes Andrew, Hugo, Charley, Katrina, and
Rita, and recent events such as Hurricane Ike continue to show the
vulnerability of our built environment. While good design and
construction cannot totally eliminate risk, every storm has shown
that sound design and construction can significantly reduce the
risk to life and damage to property. With that in mind, the Federal
Emergency Management Agency (FEMA) has developed this manual to
help the community of homebuilders, contractors, and local
engineering professionals in rebuilding homes destroyed by
hurricanes, and designing and building safer and less vulnerable
new homes. The intent of the manual is to provide homebuilders,
contractors, and engineering professionals with a series of
recommended foundation designs that will help create safer and
stronger buildings in coastal areas. The designs are intended to
help support rebuilding efforts after coastal areas have been
damaged by floods, high winds, or other natural hazards. The
foundations may differ somewhat from traditional construction
techniques; however, they represent what are considered to be some
of the better approaches to constructing strong and safe
foundations in hazardous coastal areas. The objectives used to
guide the development of this manual are: To provide residential
foundation designs that will require minimal engineering oversight;
To provide foundation designs that are flexible enough to
accommodate many of the homes identified in A Pattern Book for Gulf
Coast Neighborhoods prepared for the Mississippi Governor's
Rebuilding Commission on Recovery, Rebuilding, and Renewal; To
utilize model layouts so that many homes can be constructed without
significant additional engineering efforts. The focus of this
document is on the foundations of residential buildings. The
assumption is that those who are designing and building new homes
will be responsible for ensuring that the building itself is
designed according to the latest building code (International
Building Code(r), International Residential Code(r), and FEMA
guidance) and any local requirements. The user of this manual is
directed to other publications that also address disaster-resistant
construction. Although the foundation designs are geared to the
coastal environment subject to storm surge, waves, floating debris,
and high winds, several are suitable for supporting homes on sites
protected by levees and floodwalls or in riverine areas subjected
to high-velocity flows. Design professionals can be contacted to
ensure the foundation designs provided in this manual are suitable
for specific sites. This edition of FEMA 550 introduces the Case H
foundation, which is an open/deep foundation developed for use in
coastal high hazard areas (V zones). It is also appropriate to use
the Case H foundation in Coastal A and non-coastal A zones. Case H
foundations incorporate elevated reinforced concrete beams that
provide three important benefits. One, the elevated beams work in
conjunction with the reinforced concrete columns and grade beams to
produce a structural frame that is more efficient at resisting
lateral loads than the grade beams and cantilevered columns used in
other FEMA 550 open foundations. The increased efficiency allows
foundations to be constructed with smaller columns that are less
exposed to flood forces. The second benefit is that the elevated
reinforced concrete beams provide a continuous foundation that can
support many homes constructed to prescriptive designs from codes
and standards such as the IRC, the American Forest and Paper
Association's Wood Frame Construction Manual for One- and
Two-Family Dwellings (WFCM), and the International Code Council's
Standard for Residential Construction in High Wind Regions
(ICC-600). The third benefit that Case H foundations provide is the
ability to support relatively narrow homes. It is anticipated that
Case H foundations can be used for several styles of modular ho
This guide was developed to fulfill several different objectives
and address a wide audience with varying needs. The primary intent
is to explain the sources of nonstructural earthquake damage in
simple terms and to provide information on effective methods of
reducing the potential risks. The recommendations contained in this
guide are intended to reduce the potential hazards but cannot
completely eliminate them. The primary focus of this guide is to
help the reader understand which nonstructural items are most
vulnerable in an earthquake and most likely to cause personal
injury, costly property damage, or loss of function if they are
damaged. In addition, this guide contains recommendations on how to
implement cost effective measures that can help to reduce the
potential hazards. This guide is intended primarily for use by a
lay Audience building owners, facilities managers, maintenance
personnel, store or office managers, corporate/agency department
heads, business proprietors, homeowners, etc. Some readers may be
small-business owners with a small number of potential problems
that could be addressed in a few days' time by having at handyman
install some of the generic details presented in this guide. Other
readers may be responsible for hundreds of facilities and may need
a survey methodology to help them understand the magnitude of their
potential problems.
Early on the morning of 4th September 2010, a series of seismic
events began to unfold in Christchurch, New Zealand. They would
eventually take 185 lives and directly affect hundreds of thousands
of men, women and children. This book is a compilation of stories
from some of these people. Preschoolers, teenagers, families, and
retirees tell of the impact of the ongoing earthquakes and
aftershocks, the emotional and physical toll they exacted, and
their hope for a new Christchurch. They reflect the incredible
resilience the people of Canterbury have shown throughout this
devastating time. Some of the stories are poignant, some humorous,
some shocking and some sad. All of them are from the heart and
deserve to be heard. Magnitude 7.1 & 6.3 was put together by
Debbie Roome who is an award-winning novelist and freelance writer
with 25 years experience.
Earthquakes represent an enormous threat to the Nation. Although
damaging earthquakes occur infrequently, their consequences can be
staggering. As recent earthquakes around the world have
demonstrated, high population densities and development pressures,
particularly in urban areas, are increasingly vulnerable.
Unacceptably high loss of life and enormous economic consequences
are associated with recent global earthquakes, and it is only a
matter of time before the United States faces a similar experience.
Earthquakes cannot be prevented, but their impacts can be managed
to a large degree so that loss to life and property can be reduced.
To this end, the National Earthquake Hazards Reduction Program
(NEHRP) seeks to mitigate earthquake losses in the U.S. through
both basic and directed research and implementation activities in
the fields of earthquake science and engineering. This program is
authorized and funded by Congress and is managed as a collaborative
effort among the Federal Emergency Management Agency (FEMA), the
National Institute of Standards and Technology (NIST), the National
Science Foundation (NSF), and the United States Geological Survey
(USGS). These four Federal organizations work in close coordination
to improve the Nation's understanding of earthquake hazards and to
mitigate their effects. The missions of the four agencies are
complementary: FEMA, a component of the Department of Homeland
Security, works with states, local governments, and the public to
develop tools and improve policies and practices that reduce
earthquake losses; NIST enables technology innovation in earthquake
engineering by working with industry to remove technical barriers,
evaluate advanced technologies, and develop the measurement and
prediction tools underpinning performance standards for buildings
and lifelines; NSF strives to advance fundamental knowledge in
earthquake engineering, earth science processes, and societal
preparedness and response to earthquakes; and USGS monitors
earthquakes, assesses seismic hazard for the Nation, and researches
the basic earth science processes controlling earthquake occurrence
and effects. Mindful of the increasing threat posed by earthquakes,
NEHRP initiated a review of the scientific goals and strategies of
the Program and a discussion of the opportunities and priorities
for the five-year interval 2001-2005. This review and discussion
culminated in the new strategic plan presented here. Shaping the
plan are four goals that represent the continuum of activities in
the Program, ranging from research and development to application
and implementation. These four goals are as follows: A. Develop
effective practices and policies for earthquake loss-reduction and
accelerate their implementation. B. Improve techniques to reduce
seismic vulnerability of facilities and systems. C. Improve seismic
hazard identification and risk assessment methods and their use. D.
Improve the understanding of earthquakes and their effects.
This FEMA 154 Report, Rapid Visual Screening of Buildings for
Potential Seismic Hazards: A Handbook, is the first of a two-volume
publication on a recommended methodology for rapid visual screening
of buildings for potential seismic hazards. The technical basis for
the methodology, including the scoring system and its development,
are contained in the companion FEMA 155 report, Rapid Visual
Screening of Buildings for Potential Seismic Hazards: Supporting
Documentation. The rapid visual screening procedure (RVS) has been
developed for a broad audience, including building officials and
inspectors, and government agency and private-sector building
owners, to identify, inventory, and rank buildings that are
potentially seismically hazardous. Although RVS is applicable to
all buildings, its principal purpose is to identify (1) older
buildings designed and constructed before the adoption of adequate
seismic design and detailing requirements, (2) buildings on soft or
poor soils, or (3) buildings having performance characteristics
that negatively influence their seismic response. Once identified
as potentially hazardous, such buildings should be further
evaluated by a design professional experienced in seismic design to
determine if, in fact, they are seismically hazardous. The RVS uses
a methodology based on a "sidewalk survey" of a building and a Data
Collection Form, which the person conducting the survey (hereafter
referred to as the screener) completes, based on visual observation
of the building from the exterior, and if possible, the interior.
The Data Collection Form includes space for documenting building
identification information, including its use and size, a
photograph of the building, sketches, and documentation of
pertinent data related to seismic performance, including the
development of a numeric seismic hazard score. Once the decision to
conduct rapid visual screening for a community or group of
buildings has been made by the RVS authority, the screening effort
can be expedited by pre-planning, including the training of
screeners, and careful overall management of the process.
Completion of the Data Collection Form in the field begins with
identifying the primary structural lateral-load-resisting system
and structural materials of the building. Basic Structural Hazard
Scores for various building types are provided on the form, and the
screener circles the appropriate one. For many buildings, viewed
only from the exterior, this important decision requires the
screener to be trained and experienced in building construction.
The procedure presented in this Handbook is meant to be the
preliminary screening phase of a multi-phase procedure for
identifying potentially hazardous buildings. Buildings identified
by this procedure must be analyzed in more detail by an experienced
seismic design professional. Because rapid visual screening is
designed to be performed from the street, with interior inspection
not always possible, hazardous details will not always be visible,
and seismically hazardous buildings may not be identified as such.
Conversely, buildings initially identified as potentially hazardous
by RVS may prove to be adequate.
Nonstructural failures have accounted for the majority of
earthquake damage in several recent U.S. earthquakes. Thus, it is
critical to raise awareness of potential nonstructural risks, the
costly consequences of nonstructural failures, and the
opportunities that exist to limit future losses. Nonstructural
components of a building include all of those components that are
not part of the structural system; that is, all of the
architectural, mechanical, electrical, and plumbing systems, as
well as furniture, fixtures, equipment, and contents. Windows,
partitions, granite veneer, piping, ceilings, air conditioning
ducts and equipment, elevators, computer and hospital equipment,
file cabinets, and retail merchandise are all examples of
nonstructural components that are vulnerable to earthquake damage.
The primary purpose of this guide is to explain the sources of
nonstructural earthquake damage and to describe methods for
reducing the potential risks in simple terms. This guide is
intended for use by a non-engineer audience located within the
United States; this audience includes building owners, facility
managers, maintenance personnel, store or office managers,
corporate or agency department heads, business proprietors, risk
managers, and safety personnel. The guide is also designed to be
useful for design professionals, especially those who are not
experienced with seismic protection of nonstructural components. It
addresses nonstructural issues typically found in schools, office
buildings, retail stores, hotels, data centers, hospitals, museums,
and light manufacturing facilities. FEMA 74 explains the sources of
earthquake damage that can occur in nonstructural components and
provides information on effective methods for reducing risk
associated with nonstructural earthquake damage. It is intended for
use by a non-engineer audience that includes building owners,
facility managers, maintenance personnel, store or office managers,
corporate or agency department heads, and homeowners. The reference
material contained within the third edition of FEMA 74 is now
approaching 20 years old. A considerable amount of new information
now exists as a result of ongoing National Earthquake Hazard
Reduction Program (NEHRP) activities, local and state government
programs, private sector initiatives, and academic work focused on
reducing the potential for nonstructural earthquake damage.
Although earthquakes are an inevitable hazard, they are not
inevitable disasters. Experiences in recent years have shown
consistently that lifelines properly designed to resist earthquakes
perform well in spite of severe earthquakes; those not so designed
are subject to failure. Assessments of earthquake hazards indicate
that one or more severe earthquakes can be expected to strike U.S.
metropolitan areas in the next decade. Until actions are taken to
improve the design and construction of lifelines, failures can be
expected to result in substantial losses--estimated at billions of
dollars and many lives for a single severe earthquake. The plan
described in this document defines a process that, if activated,
will begin the development of seismic design guidelines and
standards for both new and existing lifelines. Lifelines are the
public works and utility systems that support most human
activities: individual, family, economic, political, and cultural.
The various lifelines can be classified under the following five
systems: electric power, gas and liquid fuels, telecommunications,
transportation, and water supply and sewers. This plan for
developing and adopting seismic design and construction guidelines
and standards for lifelines has been prepared in response to Public
Law 101-614, the National Earthquake Hazards Reduction Program
(NEHRP) Reauthorization Act. The act requires the Federal Emergency
Management Agency (FEMA), in consultation with the National
Institute of Standards and Technology (NIST), to develop "a plan,
including precise timetables and budget estimates, for developing
and adopting, in consultation with appropriate private sector
organizations, design and construction standards for lifelines" and
"recommendations of ways Federal regulatory authority could be used
to expedite the implementation of such standards." The Plan focuses
on developing recommendations, encouraging and supporting the
approval of these recommendations by the standards and professional
organizations serving the lifeline community, and working with the
lifeline community to achieve their effective implementation.
Design guidelines lay out a set of principles, which for lifelines
may include performance criteria, materials characteristics, and
testing procedures for design, construction, maintenance, repair,
and retrofitting of both existing and proposed systems. Guidelines
provide a basis for making judgments or determining a course of
action; they may evolve into recommendations for standards. A
standard, according to the National Standards Policy Advisory
Committee, is "a prescribed set of rules, conditions, or
requirements concerning definitions of terms; classification of
components; specification of materials, performance, or operation;
delineation of procedures; or measurement of quantity and quality
in describing materials, products, systems, services, or
practices." Properly developed and effectively implemented lifeline
seismic guidelines and standards will significantly reduce the
vulnerability of both existing and proposed lifeline systems to
future earthquakes. Guidelines and standards should (1) establish
performance criteria for the construction, maintenance, and
operation of existing and proposed lifeline systems, equipment, and
materials for selected levels of seismic risk; (2) provide a basis
for technical specifications for use by buyers and sellers of
lifeline products and services to reduce the vulnerability of
lifeline systems to earthquakes; and (3) provide a reliable basis
for regulations to protect the public health, safety, and welfare.

FEMA initiated this project in September 2004 with a contract to
the Applied Technology Council. The project was undertaken to
address the need for guidance on how to build a structure that
would be capable of resisting the extreme forces of both a tsunami
and an earthquake. This question was driven by the fact that there
are many communities along our nation's west coast that are located
on narrow spits of land and are vulnerable to a tsunami triggered
by an earthquake on the Cascadia subduction zone, which could
potentially generate a tsunami of 20 feet in elevation or more
within 20 minutes. Given their location, it would be impossible to
evacuate these communities in time, which could result in a
significant loss of life. Many coastal communities subject to
tsunami located in other parts of the country also have the same
potential problem. In these cases, the only feasible alternative is
vertical evacuation, using specially design, constructed and
designated structures built to resist both tsunami and earthquake
loads. The significance of this issue came into sharp relief with
the December 26, 2004 Sumatra earthquake and Indian Ocean tsunami.
While this event resulted in a tremendous loss of life, this would
have been even worse had not many people been able to take shelter
in multi-story reinforced concrete buildings. Without realizing it,
these survivors were among the first to demonstrate the concept of
vertical evacuation from a tsunami. This publication presents the
following information: General information on the tsunami hazard
and its history; Guidance on determining the tsunami hazard,
including the need for tsunami depth and velocity on a
site-specific basis; Different options for vertical evacuation from
tsunamis; Determining tsunami and earthquake loads and structural
design criteria necessary to address them; and, Structural design
concepts and other considerations. In September 2004 the Applied
Technology Council (ATC) was awarded a "Seismic and Multi-Hazard
Technical Guidance Development and Support" contract
(HSFEHQ-04-D-0641) by the Federal Emergency Management Agency
(FEMA) to conduct a variety of tasks, including the development of
design guidance for special facilities for vertical evacuation from
tsunamis, which ATC designated the ATC-64 Project. The effort was
co-funded by FEMA and the National Oceanic and Atmospheric
Administration (NOAA). The developmental process involved a variety
of activities including review of relevant research and
state-of-the-practice documentation and literature, preparation of
technical guidance and approaches for tsunami-resistant design,
identification of relevant tsunami loads and applicable design
criteria, development of methods to calculate tsunami loading, and
identification of desired architectural and structural system
attributes for vertical evacuation facilities. The resulting
guidance for design of special facilities for vertical evacuation
from tsunami, as presented herein, addresses a range of relevant
issues. Chapter 1 defines the scope and limitations of the
guidance. Chapter 2 provides background information on tsunami
effects and their potential impacts on buildings in coastal
communities. Chapters 3 through 7 provide design guidance on
characterization of tsunami hazard, choosing between various
options for vertical evacuation structures, locating and sizing
vertical evacuation structures, estimation of tsunami load effects,
structural design criteria, and design concepts and other
considerations. The document concludes with a series of appendices
that provide supplemental information, including examples of
vertical evacuation structures from Japan, example tsunami load
calculations, a community design example, development of impact
load equations, and background on maximum flow velocity and
momentum flux in the tsunami runup zone.
The Emergency Broadcast System (EBS) was established in 1963 to
replace the nation's first alert and warning system called
CONELRAD. The EBS allowed the President or State and local
officials to send out alerts while radio stations continued to
operate on their assigned frequencies. In 1979 the President
transferred the responsibility of maintaining the EBS from the
Department of Commerce to FEMA through Executive Order 12127. In
1990 the Primary Entry Point Advisory Committee (PEPAC) was
established by FEMA to help manage thirty-four (34) EBS Primary
Entry Point (PEP) stations across the U.S. In 1994 the Emergency
Alert System (EAS) was initiated and replaced the EBS by 1997.
Other warning systems were developed throughout the Federal
government such as National Warning System, the Digital EAS program
with the Association of Public Television Stations, the Web Alert
and Relay Network (WARN) pilot, and the Geo-Targeted Alerting
System (GTAS) with NOAA. The September 15, 1995 Presidential
Memorandum to the Director of FEMA, regarding the Emergency Alert
System (EAS) Statement of Requirements, requires FEMA to: i) Act as
the White House Military Office's Executive Agent for the
development, operations, and maintenance of the national-level EAS;
ii) Bring the Primary Entry Point (PEP) system up to full
operational capability and ensure compatibility with the state and
local EAS; iii) Phase out dedicated circuitry and associated
equipment of the Emergency Action Notification (EAN) network and
incorporate the network nodes into the national level EAS as
required; iv) Prepare guidance concerning the definition and use of
Priority Four, and enhance procedures to disseminate National
Emergency Information Programming; v) Conduct tests and exercises;
vi) Ensure the national-level EAS keeps pace with emerging
technologies through the use of low-cost innovative techniques. On
June 26, 2006 the President issued Executive Order (EO) 13407
requiring "an effective, reliable, integrated, flexible, and
comprehensive system to alert and warn the American people in
situations of war, terrorist attack, natural disaster or other
hazards to public safety and well being." The Integrated Public
Alert and Warning (IPAWS) Program Management Office (PMO) was
established in 2007 to execute the policy established in EO 13407.
The IPAWS Program goal is to identify, develop, and/or adopt
appropriate standards to enable implementation of interoperable
public alert and warning systems, to identify technologies and
standards that improve security, reliability, addressability,
accessibility, interoperability, coverage, and resilience of the
public alert and warning systems, and to integrate these
capabilities via a common IPAWS Aggregator. The IPAWS Program is
organized in to several major concurrent and incremental projects
that in coordination and partnership with other federal, state, and
local stakeholders integrate and improve all aspects of public
alert and warning. This PEA will also facilitate FEMA's compliance
with other environmental and historic preservation requirements by
providing a framework to address the impacts of actions typically
funded to aid in national preparedness. FEMA coordinates and
integrates to the maximum extent possible the review and compliance
process required under similar requirements such as the Section 106
of the National Historic Preservation Act (NHPA), Section 7 of the
Endangered Species Act (ESA), the eight step process of the
Executive Order 11988 and 11990, and others. This PEA provides a
framework on how FEMA integrates these requirements with NEPA.
Finally, the PEA provides the public and decision-makers with the
information required to understand and evaluate the potential
environmental consequences of these national preparedness actions.
This PEA meets the NEPA goals of impact identification and
disclosure and addresses the need to streamline the NEPA review
process in the interest of national preparedness.
In April 1977, President Carter issued a memorandum directing the
review of federal dam safety activities by an ad hoc panel of
recognized experts. In June 1979, the ad hoc interagency committee
on dam safety (ICODS) issued its report, which contained the first
guidelines for federal agency dam owners. The Federal Guidelines
for Dam Safety (Guidelines) encourage strict safety standards in
the practices and procedures employed by federal agencies or
required of dam owners regulated by the federal agencies. The
Guidelines address management practices and procedures but do not
attempt to establish technical standards. They provide the most
complete and authoritative statement available of the desired
management practices for promoting dam safety and the welfare of
the public. To supplement the Guidelines, ICODS prepared and
approved federal guidelines in the areas of emergency action
planning; earthquake analysis and design of dams; and selecting and
accommodating inflow design floods for dams. These publications,
based on the most current knowledge and experience available,
provided authoritative statements on the state of the art for three
important technical areas involving dam safety. In 1994, the ICODS
Subcommittee to Review/Update the Federal Guidelines began an
update to these guidelines to meet new dam safety challenges and to
ensure consistency across agencies and users. In addition, the
ICODS Subcommittee on Federal/Non-Federal Dam Safety Coordination
developed a new guideline, Hazard Potential Classification System
for Dams. With the passage of the National Dam Safety Program Act
of 1996, Public Law 104-303, ICODS and its Subcommittees were
reorganized to reflect the objectives and requirements of Public
Law 104-303. In 1998, the newly convened Guidelines Development
Subcommittee completed work on the update of all of the following
guidelines: Federal Guidelines for Dam Safety: Emergency Action
Planning for Dam Owners; Federal Guidelines for Dam Safety: Hazard
Potential Classification System for Dams; Federal Guidelines for
Dam Safety: Earthquake Analyses and Design of Dams; Federal
Guidelines for Dam Safety: Selecting and Accommodating Inflow
Design Floods for Dams; Federal Guidelines for Dam Safety: Glossary
of Terms . The publication of these guidelines marks the final step
in the review and update process. In recognition of the continuing
need to enhance dam safety through coordination and information
exchange among federal and state agencies, the Guidelines
Development Subcommittee will be responsible for maintaining these
documents and establishing additional guidelines that will help
achieve the objectives of the National Dam Safety Program.
The Interagency Committee on Dam Safety (ICODS) was established to
provide the Federal agencies involved in dam safety with the
opportunity to coordinate their dam safety activities. One of the
goals of ICODS is to provide a common forum for the Federal
agencies and State officials to exchange ideas and procedures that
are used for dam safety and to provide an efficient mechanism for
technology transfer. The purpose of this document is to establish a
common Glossary of Terms for Dam Safety.
Damage to earthen dams and dam safety issues associated with tree
and woody vegetation penetrations of earthen dams is all too often
believed to be a routine maintenance situation by many dam owners,
dam safety regulators, and engineers. Contrary to this belief, tree
and woody vegetation penetrations of earthen dams and their
appurtenances have been demonstrated to be causes of serious
structural deterioration and distress that can result in failure of
earthen dams. For the first time in the history of dam safety, a
Research Needs Workshop on Plant and Animal Impacts on Earthen Dams
(Workshop) was convened through the joint efforts of the Federal
Emergency Management Agency (FEMA) and the Association of State Dam
Safety Officials (ASDSO) in November 1999 to bring together
technical resources of dam owners, engineers, state and federal
regulators, wildlife managers, foresters, and members of academia
with expertise in these areas. The Workshop highlighted the
realization that damage to earthen dams resulting from plant and
animal penetrations was indeed a significant dam safety issue in
the United States. The purpose of this Technical Manual for Dam
Owners, Impacts of Plants on Earthen Dams is to convey technology
assembled through the Workshop by successful completion of four
objectives. These objectives are as follows: 1. Advance awareness
of the characteristics and seriousness of dam safety problems
associated with tree and woody vegetation growth impacts on earthen
dams; 2. Provide a higher level of understanding of dam safety
issues associated with tree and woody vegetation growth impacts on
earthen dams by reviewing current damage control policies; 3.
Provide state-of-practice guidance for remediation design
considerations associated with damages associated with tree and
woody vegetation growth on earthen dams; and 4. Provide rationale
and state-of-practice techniques and procedures for management of
desirable and undesirable vegetation on earthen dams.
This Programmatic Environmental Assessment (PEA) provides an
assessment of the expected environmental impacts associated with
the implementation of the programs funded by the Federal Emergency
Management Agency's (FEMA) Grant Programs Directorate (GPD). The
proposed implementation of GPD-funded grant programs would involve
a wide variety of projects designed to improve the preparedness and
readiness of public safety and first response agencies, as well as
improve homeland security through increased protection of the
Nation's critical infrastructure. The Department of Homeland
Security (DHS) Office of Grants and Training (G&T) was
transformed into GPD on April 1, 2007, as a result of the
Post-Katrina Emergency Management Reform Act of 2006. GPD is housed
within FEMA to oversee the grant business operations, systems,
training, and policy. FEMA coordinates the federal government's
role in preparing for, preventing, mitigating the effects of,
responding to, and recovering from all domestic disasters, whether
natural or man-made, including acts of terror. The preparedness
grant programs managed by GPD enhance the preparedness and response
capabilities of States, Territories, Tribes, private-sector and
non-governmental first responders to respond to terrorist attacks
and non-man made emergencies. These funds are intended to develop
and administer planning, training, and equipment assistance
programs for state and local emergency response agencies to better
prepare them against the threat of terrorism as part of GPD's
mission. GPD's mission is to manage Federal assistance to
measurably improve capability and reduce the risks the Nation
faces. GPD is responsible for the program management and
administration of 19 preparedness grant programs. GPD will ensure
all of their preparedness grant programs are aligned to, and are
measurable against, the National Preparedness Guidelines and the
National Priorities as authorized by the H.R. 10, 9/11 Commission
Recommendations Implementation Act. These preparedness grant
programs support the achievement of the National Preparedness Goal
by providing funds for State and local homeland security efforts,
such as planning, equipment purchase, protection of critical
infrastructure by reinforcing physical security and access
controls, and hiring and training first response personnel.
Currently, the grants administered by GPD funds are provided to all
56 States and Territories. The events of September 11, 2001
highlighted critical needs in the Nation's security safeguards and
systems. Effective preparedness is a critical precondition of
successful response. In order to best equip State and local
governments, as well quasi-governmental private entities, to
successfully respond to emergencies, GPD is committed to providing
funds that will allow these entities to improve preparedness. These
grant programs are part of a comprehensive set of measures
authorized by Congress and implemented by FEMA to help strengthen
the Nation against risks associated with potential terrorist
attacks. This PEA examines the direct, indirect, and cumulative
environmental impacts associated with the GPD-funded grant
programs. This document has been prepared in compliance with the
National Environmental Policy Act of 1969 (NEPA) and the FEMA
regulations for implementing NEPA.
The Federal Emergency Management Agency (FEMA) Benefit-Cost
Analysis (BCA) program, developed in the early 1990s, is used to
determine the cost effectiveness of proposed mitigation projects
for several FEMA mitigation grant programs. In 2008, FEMA
collaborated with many Applicants and subapplicants on enhancements
to update values in the software and to make it more efficient. The
purpose of the BCA Reference Guide is to provide BCA software users
with an overview of the grant programs, application development,
benefits and costs, and the location of BCA guidance documents and
helpful information. This guide also outlines sources of additional
information needed to use the software to obtain a Benefit-Cost
Ratio (BCR) for a single project or multiple projects. Hazard
mitigation is any sustained action taken to reduce or eliminate
long-term risk to people and property from natural hazards and
their effects. This definition distinguishes actions that have a
long-term impact from those that are more closely associated with
immediate preparedness, response, and recovery activities. Hazard
mitigation is the only phase of emergency management specifically
dedicated to breaking the cycle of damage, reconstruction, and
repeated damage. As such, States, Territories, Indian Tribal
governments, and communities are encouraged to take advantage of
the funding provided by Hazard Mitigation Assistance (HMA) programs
in both the pre- and post-disaster periods. The Department of
Homeland Security (DHS) and FEMA HMA programs provide a critical
opportunity to reduce the risk to individuals and property from
natural hazards, while simultaneously reducing reliance on Federal
disaster funds. HMA guidance provides continuity between five FEMA
mitigation grant programs: the Hazard Mitigation Grant Program
(HMGP), Pre-Disaster Mitigation (PDM), Flood Mitigation Assistance
(FMA), Repetitive Flood Claims (RFC), and Severe Repetitive Loss
(SRL) programs. Each HMA program was authorized by a separate
legislative action, and as such, each program differs slightly in
scope and intent, but all of them provide significant opportunities
to reduce or eliminate potential losses to State, Tribal, and local
assets. HMGP may provide funds to States, Territories, Indian
Tribal governments, local governments, and eligible private
non-profits following a Presidential major disaster declaration.
The PDM, FMA, RFC, and SRL programs may provide funds annually to
States, Territories, Indian Tribal governments, and local
governments. While the statutory origins of the programs differ,
all share the common goal of reducing the risk of loss of life and
property due to natural hazards. This publication was prepared with
