On August 29, 2005, Hurricane Katrina caused extensive damage to
the coast along the Gulf of Mexico, resulting in an unprecedented
relief, recovery, and reconstruction effort. This reconstruction
presents a unique opportunity to rebuild the communities and public
infrastructure using the latest hazard mitigation techniques proven
to be more protective of lives and property. Critical facilities
comprise all public and private facilities deemed by a community to
be essential for the delivery of vital services, protection of
special populations, and the provision of other services of
importance for that community. This manual concentrates on a
smaller group of facilities that are crucial for protecting the
health and safety of the population: health care, educational, and
emergency response facilities. The Design Guide for Improving
Critical Facility Safety from Flooding and High Winds (FEMA 543)
was developed with the support of the Federal Emergency Management
Agency (FEMA) Region IV in the aftermath of Hurricane Katrina. This
manual recommends incorporating hazard mitigation measures into all
stages and at all levels of critical facility planning and design,
for both new construction and the reconstruction and rehabilitation
of existing facilities. It provides building professionals and
decision makers with information and guidelines for implementing a
variety of mitigation measures to reduce the vulnerability to
damage and disruption of operations during severe flooding and
high-wind events. The underlying theme of this manual is that by
building more robust critical facilities that will remain
operational during and after a major disaster, people's lives and
the community's vitality can be better preserved and protected. The
poor performance of many critical facilities in the affected areas
was not unique to Hurricane Katrina. It was observed in numerous
hurricanes dating back more than three decades. Several reasons may
explain this kind of performance. In many cases the damaged
facilities were quite old and were constructed well before the
introduction of modern codes and standards. Some of the older
facilities were damaged because building components had
deteriorated as a result of inadequate maintenance. Many
fa-cilities occupy unsuitable buildings that were never intended
for this type of use. Some newer facilities suffered damage as a
result of deficiencies in design and construction or the
application of inappropriate design criteria and standards. The
primary objective of this manual is to assist the building design
community and local officials and decision makers in adopting and
implementing sound mitigation measures that will decrease the
vulnerability of critical facilities to major disasters. The goals
of this manual are to: Present and recommend the use of building
design features and building materials and methods that can improve
the performance of critical facilities in hazard-prone areas during
and after flooding and high-wind events. m Introduce and provide
guidelines for implementing flooding and high-wind mitigation best
practices into the process of design, construction, and operation
and maintenance of critical facilities; and To aid in the
reconstruction of the Gulf Coast in the wake of Hurricane Katrina,
this manual presents an overview of the principal planning and
design considerations for improving the performance of critical
facilities during, and in the aftermath of, flooding and high-wind
events. It provides design guidance and practical recommendations
for protecting critical facilities and their occupants against
these natural hazards. It presents incremental approaches that can
be implemented over time to decrease the vulnerability of
buildings, but emphasizes the importance of incorporating the
requirements for mitigation against flooding and high winds into
the planning and design of critical facilities from the very
beginning of the process.
The residential portion of the fire problem continues to account
for the vast majority of civilian casualties. National Fire
Protection Association (NFPA) estimates show that, while
residential structure fires account for only 25 percent of fires
nationwide, they account for a disproportionate share of losses: 83
percent of fire deaths, 77 percent of fire injuries, and 64 percent
of direct dollar losses. Analyses of the residential structure fire
problem were published formerly as a chapter in each edition of
Fire in the United States. The most recent edition of Fire in the
United States, the fourteenth edition published in August 2007,
featured an abbreviated chapter on residential structures. This
full report is the most current snapshot of the residential fire
problem as reflected in the 2005 National Fire Incident Reporting
System (NFIRS) data and the 2005 NFPA survey data. In this report,
as in previous chapters in Fire in the United States, an attempt
has been made to keep the data presentation and analysis as
straightforward as possible. It is also the desire of the United
States Fire Administration (USFA) to make the report widely
accessible to many different users, so it avoids unnecessarily
complex methodology.
This publication helps to develop a comprehensive juvenile
firesetter prevention training workshop for the various agency
professionals who work with juvenile firesetters. Juveniles are
responsible for a significant proportion of both the accidental and
intentional fires that occur each year in the United States. Since
the mid-1970's, national, state, and local officials have been
turning more attention to the problem of juvenile firesetting and
have experimented with various approaches to reducing it.
Nonetheless, many experts believe that there are significant gaps
in our knowledge and practice. In response to these concerns, in
1987 the Office of Juvenile Justice and Delinquency Prevention
(OJJDP) and the U.S. Fire Administration (USFA) began a new
research and development program intended to conceptualize, design,
develop, and evaluate a variety of community-based approaches to
prevent and control juvenile firesetting. The initiative was known
as the National Juvenile Firesetter/Arson Control and Prevention
Program (NJF/ACP). This Users' Guide is designed to accompany The
Juvenile Firesetter/Arson Control and Prevention Program (JFACPP)
Program Materials. The Users' Guide is intended to accomplish the
following objectives: 1. To provide a summary of how to plan and
implement a juvenile firesetter/arson control and prevention
program. This is achieved by outlining critical decision points in
building each component of the juvenile firesetter/arson program.
The result is a cookbook format that guides the reader from the
planning to the execution of an effective community program. 2. To
highlight the key information contained in The JFACPP Guidelines
for Implementation.

This report compiles the best practices and common problems of fire
protection and criminal justice agencies in identifying,
investigating, prosecuting, and preventing arson. Commonly, the
crime of arson is motivated by spite and revenge. Perpetrators
strike with fire at buildings where people live, work, or
socialize-causing injury, property loss, and death. Civilians and
firefighters alike die in arson fires every year. Thirty years ago,
arson captured media attention because so-called arson-for-profit
rings were burning down decaying urban neighborhoods that had
ceased to be profitable, and then rebuilding them at a substantial
profit. Other high-profile cases involved arsonists who were
connected to gangs and drug lords, and who set fires to intimidate
their rivals or as retribution for deals gone bad. Some of the most
publicized cases occurred in the cities of New York, Boston,
Houston, Los Angeles, Miami, Baltimore, and others. There even were
situations where neighborhood vigilantes, who were frustrated with
crime and run-down buildings, took it upon themselves to torch
structures to rid the neighborhood of vagrants, prostitutes, and
drug dealers. Insurance companies were perceived as the main
victims from intentional fires. As a crime com-mitted against
property, the economics of arson played center stage to the less
well-defined statistics on injuries and deaths. Since arson fires
do, on average, cause proportionately higher losses than fires from
other causes, insurance companies committed many resources toward
investigation and control. From establishing tip reward programs,
training accelerant detection canines (ADC's), supporting arson
reporting immunity legislation, and establishing the property
insurance loss register (PILR), the insurance industry was a strong
partner at that time. There is a dichotomy between arson as a
property crime and arson as a crime against people, and that lies
at the heart of today's challenges with cases of arson. As a crime,
arson's long-standing definition as the willful and malicious
burning of property does not do justice to the fact that today
arson is usually a personal crime that is directed intentionally
against specific victims. It is time for arson to be dealt with as
a violent crime against persons, not just a crime against property.
Today, spite and revenge dominate as the motives in intentional
property fires, especially where there are casualties.
Revenge-minded arsonists torch nightclubs, occupied residences,
hotels, and other settings where their intended victims, and often
other innocent people, are injured and killed. First responders get
injured or die battling these blazes and trying to save others.
Even though a portion of incendiary fires are motivated by other
reasons (e.g., excitement, economic relief, peer pressure, a cry
for help, and so forth) most set fires happen because someone
wanted to inflict harm on another person using fire as the weapon
of choice. Fire investigation units from The U.S. Fire
Administration's (USFA's) project indicated that spite and revenge
were the most common motives behind incendiary fires. Among project
sites from the past 5 years, spite and revenge ranked as the
highest leading motives, when investigation units were queried
about prevailing motives.
This Wildfire Prevention Guide is a project of the National
Wildfire Coordinating Group. This is one in a series designed to
provide information and guidance for personnel who have interests
and/or responsibilities in fire prevention. Each guide in the
series addresses an individual component of a fire prevention
program. In addition to providing insight and useful information,
each guide suggests implementation strategies and examples for
utilizing this information. Each Wildfire Prevention Guide has been
developed by Fire Prevention Specialists and subject-matter experts
in the appropriate area. The goal of this series is to improve and
enhance wildfire prevention programs and to facilitate the
achievement of NWCG program goals.
The 2005 Fire Service Needs Assessment Survey was conducted as a
stratified random sample survey. The NFPA used its own list of
local fire departments as the mailing list and sampling frame of
all fire departments in the US that report on fire incidents
attended. In all, 15,545 fire departments - just over half the
total in NFPA Fire Service Inventory (FSI) database, including all
departments protecting communities of at least 50,000 population -
were mailed survey forms, and 4,709 responded, for a 30% response
rate. Because of time constraints, this second survey limited its
second mailing to larger departments and states with unusually low
response rates, whereas the first survey in 2001 had included a
second mailing to all first-mailing non-respondents. This response
rate is similar to the response rate in the 2001 survey's first
mailing and is sufficient for reliable results at the national and
state levels, overall and by community size. The second mailing to
small states with low response rates had minimal impact on national
estimates. The content of the survey was developed by NFPA in the
2001 survey, in collaboration with an ad hoc technical advisory
group consisting of representatives of the full spectrum of
national organizations and related disciplines associated with the
management of fire and related hazards and risks in the U.S. The
survey form was used without modification in order to maximize
comparability of results and development of valid timelines.
Hurricane Sandy caused extensive human suffering and damage to
public and private property. In response to this catastrophic
event, Congress considered legislation to provide supplemental
appropriations to federal disaster assistance programs. In
addition, Congress considered revisions to the Robert T. Stafford
Disaster Relief and Emergency Assistance Act (the Stafford Act,
P.L. 93-288 as amended), which is the primary source of authorities
for disaster assistance programs for the Federal Emergency
Management Agency (FEMA). As a result, Congress passed the Sandy
Recovery Improvement Act of 2013, which was included as Division B
of the Disaster Relief Appropriations Act, 2013 (P.L. 113-2).
Division A of P.L. 113-2 provided a $50.7 billion package of
disaster assistance largely focused on responding to Hurricane
Sandy. Additionally, Congress increased the National Flood
Insurance Program's borrowing authority by $9.7 billion (from
$20.725 billion to $30.425 billion) (P.L. 113-1). Both of these
supplemental relief law are discussed separately in CRS Report
R42869, FY2013 Supplemental Funding for Disaster Relief. This
report analyzes the provisions of the Sandy Recovery Improvement
Act of 2013. In general, these provisions amend the Stafford Act
with a stated goal of improving the efficiency and quality of
disaster assistance provided by FEMA. Briefly, the amendments to
the Stafford Act include: Establishing a new set of alternative
procedures for administering the Public Assistance Program, which
provides assistance for debris removal and the repair and
restoration of eligible facilities (Section 1102 of the Sandy
Recovery Improvement Act of 2013); Authorizing FEMA to enter into
agreements with private owners of multi-family rental properties to
expand post-disaster housing resources (Section 1103); Revising the
administration of the Hazard Mitigation Grant Program, to include a
possible advancement of 25% of grant funds (Section 1104);
Directing the establishment of alternative dispute resolution
procedures (including binding arbitration), building on FEMA's
current appeals process, to resolve federal and state disagreements
on costs and eligibility questions (Section 1105); Directing the
creation of a joint process for environmental and historical review
for disaster recovery projects with the goal of increasing the
speed of the process (Section 1106); Directing FEMA to study, and
report to Congress, whether it is appropriate to increase the
dollar size of "small projects" eligible for simplified procedures
(Section 1107); Including child care as an eligible expense under
the "other needs assistance" provided in certain disasters (Section
1108(a)); Specifically authorizing the reimbursement of the base
wages of government employees providing emergency work under
certain circumstances (Section 1108(b)); Directing FEMA to update
the factors considered when assessing the need for Individual
Assistance in the declaration process (Section 1109); Authorizing
the chief executive of a tribal government to directly request
disaster or emergency declarations from the President, much as a
governor can for a state (Section 1110); and Directing FEMA to
create a comprehensive national strategy for reducing the cost of
future disasters (Section 1111). Prospectively, the changes in law
apply to disasters declared on or after the date of enactment,
January 29, 2013. Further, support can be found in the text and
legislative history of the bill for applying at least some of these
amendments retrospectively to Hurricane Sandy-related disaster
declarations. However, it is less clear whether, and to what
extent, some of these revisions will apply to disasters declared
before Hurricane Sandy.
Families trust schools to keep their children safe during the day.
Thanks to the efforts of millions of teachers, principals, and
staff across America, the majority of schools remain safe havens
for our nation's youth. The unfortunate reality is, however, that
school districts in this country may be touched either directly or
indirectly by a crisis of some kind at any time. Natural disasters
such as floods, earthquakes, fires, and tornadoes can strike a
community with little or no warning. An influenza pandemic, or
other infectious disease, can spread from person-to-person causing
serious illness across the country, or around the globe, in a very
short time. School shootings, threatened or actual, are extremely
rare but are horrific and chilling when they occur. The harrowing
events of September 11 and subsequent anthrax scares have ushered
in a new age of terrorism. Communities across the country are
struggling to understand and avert acts of terror. Children and
youth rely on and find great comfort in the adults who protect
them. Teachers and staff must know how to help their students
through a crisis and return them home safely. Knowing what to do
when faced with a crisis can be the difference between calm and
chaos, between courage and fear, between life and death. There are
thousands of fires in schools every year, yet there is minimal
damage to life and property because staff and students are
prepared. This preparedness needs to be extended to all risks
schools face. Schools and districts need to be ready to handle
crises, large and small, to keep our children and staff out of
harm's way and ready to learn and teach. Taking action now can save
lives, prevent injury, and minimize property damage in the moments
of a crisis. The importance of reviewing and revising school and
district plans cannot be underscored enough, and Practical
Information on Crisis Planning: A Guide for Schools and Communities
is designed to help you navigate this process. The Guide is
intended to give schools, districts, and communities the critical
concepts and components of good crisis planning, stimulate thinking
about the crisis preparedness process, and provide examples of
promising practices. This document does not provide a cookbook
approach to crisis preparedness. Each community has its own
history, culture, and way of doing business. Schools and districts
are at risk for different types of crises and have their own
definitions of what constitutes a crisis. Crisis plans need to be
customized to communities, districts, and schools to meet the
unique needs of local residents and students. Crisis plans also
need to address state and local school safety laws. Experts
recommend against cutting and pasting plans from other schools and
districts. Other plans can serve as useful models, but what is
effective for a large innercity school district where the
population is concentrated may be ineffective for a rural community
where schools and first responders are far apart.
Hurricane Ivan made landfall on Thursday, September 16, 2004, just
west of Gulf Shores, Alabama. The hurricane brought sustained wind
speeds, torrential rains, coastal storm surge flooding, and large
and battering waves along the western Florida Panhandle and Alabama
coastline. After landfall, Hurricane Ivan gradually weakened over
the next week, moving northeastward over the Southeastern United
States and eventually emerging off the Delmarva Peninsula as an
extratropical low on September 19, 2004. On September 18, 2005, the
Federal Emergency Management Agency's (FEMA's) Mitigation Division
deployed a Mitigation Assessment Team (MAT) to Alabama and Florida
to evaluate building performance during Hurricane Ivan and the
adequacy of current building codes, other construction
requirements, and building practices and materials. This report
presents the MAT's observations, conclusions, and recommendations
as a result of those field investigations. Several maps in Chapter
1 illustrate the path of the storm, the depth of storm surge along
the path, and the wind field estimates. Hurricane Ivan approximated
a design flood event on the barrier islands and exceeded design
flood conditions in sound and back bay areas. This provided a good
opportunity to assess the adequacy of National Flood Insurance
Program (NFIP) floodplain management requirements as well as
current construction practices in resisting storm surge and wave
damage. FEMA was particularly interested in evaluating damages to
buildings in coastal A Zones where V-Zone construction methods are
not required. The recommendations in this report are based solely
on the observations and conclusions of the MAT, and are intended to
assist the State of Alabama, the State of Florida, local
communities, businesses, and individuals in the reconstruction
process and to help reduce damage and impact from future natural
events similar to Hurricane Ivan. The report and recommendations
also will help FEMA assess the adequacy of its flood hazard mapping
and floodplain management requirements and determine whether
changes are needed or additional guidance required. The general
recommendations are presented in Sections 8.1 and 8.2. They relate
to policies and education/outreach that are needed to ensure that
designers, contractors, and building officials understand the
requirements for disaster-resistant construction in hurricane-prone
regions. Proposed changes to codes and standards are presented in
Section 8.3. Specific recommendations for improving the performance
of the building structural system and envelope, and the protection
of critical and essential facilities (to prevent loss of function)
are provided in Chapter 8. Implementing these specific
recommendations, in combination with the general recommendations of
Section 8.1 and 8.2 and the code and standard recommendations of
Section 8.3, will significantly improve the ability of buildings to
resist damage from hurricanes. Recommendations specific to
structural issues, building envelope issues, critical and essential
facilities, and education and outreach have also been provided. As
the people of Alabama and Florida rebuild their lives, homes, and
businesses, there are a number of ways they can minimize the
effects of future hurricanes.
Following the two damaging California earthquakes in1989 (Loma
Prieta) and 1994 (Northridge), many concrete wall and masonry wall
buildings were repaired using federal disaster assistance funding.
The repairs were based on inconsistent criteria, giving rise to
controversy regarding criteria for the repair of cracked concrete
and masonry wall buildings. To help resolve this controversy, the
Federal Emergency Management Agency (FEMA) initiated a project on
evaluation and repair of earthquake-damaged concrete and masonry
wall buildings in 1996. The ATC-43 project addresses the
investigation and evaluation of earthquake damage and discusses
policy issues related to the repair and upgrade of
earthquake-damaged buildings. The project deals with buildings
whose primary lateral-force-resisting systems consist of concrete
or masonry bearing walls with flexible or rigid diaphragms, or
whose vertical-load-bearing systems consist of concrete or steel
frames with concrete or masonry infill panels. The intended
audience is design engineers, building owners, building regulatory
officials, and government agencies. The project results are
reported in three documents. TheFEMA306report, Evaluation of
Earthquake Damaged Concrete and Masonry Wall Buildings, Basic
Procedures Manual, provides guidance on evaluating damage and
analyzing future performance. Included in the document are
component damage classification guides, and test and inspection
guides. FEMA 307, Evaluation of Earthquake Damaged Concrete and
Masonry Wall Buildings, Technical Resources, contains supplemental
information including results from a theoretical analysis of the
effects of prior damage on single-degree-of-freedom mathematical
models, additional background information on the component guides,
and an example of the application of the basic procedures. FEMA
308, The Repair of Earthquake Damaged Concrete and Masonry Wall
Buildings, discusses the policy issues pertaining to the repair of
earthquake-damaged buildings and illustrates how the procedures
developed for the project can be used to provide a technically
sound basis for policy decisions. It also provides guidance for the
repair of damaged components.
Floods, hurricanes, and other disasters can strike with little
warning and damage or destroy irreplaceable art, artifacts, books,
and historic records. But there are ways to prepare for emergencies
and minimize the damage they inflict. Since the events of September
11, 2001, effective emergency management has become a higher
priority for the cultural community. More institutions are
interested in developing disaster plans, providing staff training,
and better protecting their collections. Numerous federal programs
now support such important efforts. Before and After Disasters:
Federal Funding for Cultural Institutions is designed to help
archives, arts centers, libraries, museums, historical societies,
and historic sites find the resources they need. This guide is an
updated and expanded version of Resources for Recovery:
Post-Disaster Aid for Cultural Institutions, first developed in
1992 by Heritage Preservation and then revised in 2000. Before and
After Disasters includes summary descriptions and contact
information for 15 federal grant and loan programs - almost double
the number of resources in the previous edition. It covers sources
of federal assistance for preparedness, mitigation, and response,
as well as for recovery. Sample projects in disaster planning,
training, treatment research, and restoration illustrate the
funding guidelines. Before and After Disasters: Federal Funding for
Cultural Institutions is an initiative of the Heritage Emergency
National Task Force. It was written and produced by Heritage
Preservation with funding from, and in partnership with, the
Federal Emergency Management Agency and the National Endowment for
the Arts as a service to the American cultural community.
The American Red Cross is the nation's largest nonprofit
organisation involved in disaster relief. The organisation provides
services such as sheltering and food assistance, and it has a
leadership role in the federal disaster response framework.
However, questions have been raised over its ability to respond
effectively to large disasters. This book addresses the key factors
affecting the nature and extent of the Red Cross's disaster
services; how it coordinates with the federal government on
disaster assistance; and what external oversight exists of its
disaster services. Furthermore, the book provides a brief history
of the charter of the American National Red Cross (ANRC); describes
the recent congressional interest in the ANRC's governance,
operations, and charter; reviews the ANRC's governance audit report
and proposal to amend its charter; and describes recent
congressional proposals to amend the charter.
The goal of the "Provisions" is to present criteria for the design
and construction of new structures subject to earthquake ground
motions in order to minimize the hazard to life for all structures,
to increase the expected performance of structures having a
substantial public hazard due to occupancy or use as compared to
ordinary structures, and to improve the capability of essential
facilities to function after an earthquake. The "Provisions"
provides the minimum criteria considered prudent for the protection
of life safety in structures subject to earthquakes. The
"Provisions" document has been reviewed extensively and balloted by
the architectural, engineering, and construction communities and,
therefore, it is a proper source for the development of building
codes in areas of seismic exposure. Some design standards go
further than the "Provisions" and attempt to minimize damage as
well as protect building occupants. The "Provisions" document
generally considers property damage as it relates to occupant
safety for ordinary structures. For high occupancy and essential
facilities, damage limitation criteria are more strict in order to
better provide for the safety of occupants and the continued
functioning of the facility. Some structural and nonstructural
damage can be expected as a result of the "design ground motions"
because the "Provisions" allow inelastic energy dissipation in the
structural system. For ground motions in excess of the design
levels, the intent of the Provisions is for the structure to have a
low likelihood of collapse. It must be emphasized that absolute
safety and no damage even in an earthquake event with a reasonable
probability of occurrence cannot be achieved for most structures.
However, a high degree of life safety, albeit with some structural
and nonstructural damage, can be achieved economically in
structures by allowing inelastic energy dissipation in the
structure. The objective of the "Provisions" therefore is to set
forth the minimum requirements to provide reasonable and prudent
life safety. For most structures designed and constructed according
to the "Provisions," it is expected that structural damage from
even a major earthquake would likely be repairable, but the damage
may not be economically repairable. Where damage control is
desired, the design must provide not only sufficient strength to
resist the specified seismic loads but also the proper stiffness to
limit the lateral deflection. Damage to nonstructural elements may
be minimized by proper limitation of deformations; by careful
attention to detail; and by providing proper clearances for
exterior cladding, glazing, partitions, and wall panels. The
nonstructural elements can be separated or floated free and allowed
to move independently of the structure. If these elements are tied
rigidly to the structure, they should be protected from
deformations that can cause cracking; otherwise, one must expect
such damage. It should be recognized, however, that major
earthquake ground motions can cause deformations much larger than
the specified drift limits in the "Provisions." Where prescribed
wind loading governs the stress or drift design, the resisting
system still must conform to the special requirements for
seismic-force-resisting systems. This is required in order to
resist, in a ductile manner, potential seismic loadings in excess
of the prescribed loads. A proper, continuous load path is an
obvious design requirement for equilibrium, but experience has
shown that it often is overlooked and that significant damage and
collapse can result. The basis for this design requirement is
twofold: 1. To ensure that the design has fully identified the
seismic-force-resisting system and its appropriate design level and
2. To ensure that the design basis is fully identified for the
purpose of future modifications or changes in the structure.
On September 22, 1992, at the request of the Mayor of Kauai County,
the Federal Coordinating Officer for the Iniki disaster tasked the
Federal Emergency Management Agency's (FEMA's) Federal Insurance
Administration (FIA) to assemble a team of experts to assess the
performance of buildings. The team was tasked with surveying the
performance of primarily residential structures under wind and
water forces generated during Hurricane Iniki. The goal of this
effort is to provide guidance and offer recommendations for
reducing damage from future hurricanes. This goal is best met
through learning from both failures and successes of building
performance. During the field assessment, the team investigated
primarily structural systems (i.e., systems in a building that
resist lateral and vertical forces. For all buildings, the
performance of exterior architectural systems, such as roofing,
windows, and doors was analyzed. The analysis also included the
effects of windborne and waterborne debris and the quality of
construction and materials. The majority of building types observed
were one- and two-story, wood-frame, single-family and multi-family
residential structures. However, pre-engineered steel commercial
and industrial buildings, as well as resort hotels and condominiums
constructed of reinforced concrete and masonry, were also examined.
This report includes detailed engineering discussions of building
failure modes and successful building performance. It also provides
detailed recommendations for enhancing building performance under
hurricane and flood conditions.
According to available information, landsliding in the United
States causes an average of 25 to 50 deaths and $1 to $2 billion in
economic losses annually. Although all 50 states are subject to
landslide activity, the Rocky Mountain, Appalachian, and Pacific
Coast regions generally suffer the greatest landslide losses. The
costs of landsliding can be direct or indirect and range from the
expense of cleanup and repair or replacement of structures to lost
tax revenues and reduced productivity and property values.
Landslide losses are growing in the United States despite the
availability of successful techniques for landslide management and
control. The failure to lessen the problem is primarily due to the
ever-increasing pressure of development in areas of geologically
hazardous terrain and the failure of responsible government
entities and private developers to recognize landslide hazards and
to apply appropriate measures for their mitigation, even though
there is overwhelming evidence that landslide hazard mitigation
programs serve both public and private interests by saving many
times the cost of implementation. The high cost of landslide damage
will continue to increase if community development and capital
investments continue without taking advantage of the opportunities
that currently exist to mitigate the effects of landslides. The
widespread occurrence of landsliding, together with the potential
for catastrophic statewide and regional impacts, emphasizes the
need for cooperation among federal, state, and local governments
and the private sector. Although annual landslide losses in the
U.S. are extremely high, significant reductions in future losses
can be achieved through a combination of landslide hazard
mitigation and emergency management. Landslide hazard mitigation
consists of those activities that reduce the likelihood of
occurrence of damaging landslides and minimize the effects of the
landslides that do occur. The goal of emergency management is to
minimize loss of life and property damage through the timely and
efficient commitment of available resources. Despite their common
goals, emergency management and hazard mitigation activities have
historically been carried out independently. The integration of
these two efforts is most often demonstrated in the recovery phase
following a disaster, when decisions about reconstruction and
future land uses in the community are made. The development and
implementation of landslide loss-reduction strategies requires the
cooperation of many public and private institutions, all levels of
government, and private citizens. Coordinated and comprehensive
systems for landslide hazard mitigation do not currently exist in
most states and communities faced with the problem. In most states,
local governments often take the lead by identifying goals and
objectives, controlling land use, providing hazard information and
technical assistance to property owners and developers, and
implementing mitigation projects as resources allow. State and
federal agencies play supporting roles-primarily financial,
technical, and administrative. In some cases, however, legislation
originating at the state or federal level is the sole impetus for
stimulating effective local mitigation activity. In many states
there remains a need to develop long-term organizational systems at
state and local levels to deal with landslide hazard mitigation in
a coordinated and systematic manner. The development of a landslide
hazard mitigation plan can be the initial step in the establishment
of state and local programs that promote long-term landslide loss
reduction. The purpose of this guidebook is to provide a practical,
politically feasible guide for state and local officials involved
in landslide hazard mitigation. The guidebook presents concepts and
a framework for the preparation of state and local landslide hazard
mitigation plans.
During the past few decades, the number of large public warehouse
stores (often referred to as big-box stores) across the nation has
grown significantly, changing both consumer buying habits and the
public's risk of injury during earthquakes. During an earthquake,
occupant safety in a big-box store depends on both the structural
performance of the building and on the performance of the storage
racks and their contents. Earthquake ground motions can cause
storage racks to collapse or overturn if they are not properly
designed, installed, maintained, and loaded. In addition, goods
stored on the racks may spill or topple off. Both occurrences pose
a life-safety risk to the exposed shopping public. The immediate
stimulus for the project that resulted in this report was a 2003
request from the State of Washington to the Federal Emergency
Management Agency (FEMA) for guidance concerning the life-safety
risk posed by the storage racks in publicly accessible areas of
retail stores, especially the risk of rack collapse of loss of
stored goods during an earthquake. FEMA asked the Building Seismic
Safety Council (BSSC) to develop the requested guidance. To do so,
the BSSC established a Rack Project Task Group composed of
practicing engineers, storage rack designers, researchers,
representatives of the Rack Manufacturers Institute (RMI) and the
Retail Industry Leaders Association, and members of applicable
technical subcommittees responsible for updating the NEHRP
Recommended Provisions. In developing this guidance document, the
Task Group focused primarily on steel single selective pallet
storage racks. It reviewed available information on storage rack
performance during earthquakes and the background on the
development of standards and code requirements for storage racks;
assessed seismic requirements for storage racks and current
practices with respect to rack design, maintenance and operations,
quality assurance, and post-earthquake inspections; and examined
available research and testing data. Based on its study, the Task
Group developed short-term recommendations to improve current
practice and formulated long-term recommendations to serve as the
basis for improved standards documents such as the NEHRP
Recommended Provisions, ASCE 7, and the RMI-developed storage rack
specification. Over the near term, the Task Group recommends that
the 2003 NEHRP Recommended Provisions requirements for steel single
selective pallet storage rack design be followed and that
connections be checked in accordance with a procedure to be
developed by RMI. The Task Group also recommends that additional
guidance presented in this report be voluntarily adopted by store
owners and operators. Further, given the fact that maintenance and
use of storage racks is a key element to their acceptable
performance during earthquakes, store owners and operators should
adopt an appropriate quality assurance plan; as a minimum, the best
self-imposed practices of store owners and operators should be
maintained. The Task Group's primary long-term recommendation is
that the RMI specification be brought into conformance with the
2003 NEHRP Recommended Provisions, which is the basis for seismic
requirements found in current seismic design standards and model
building codes. The Task Group also recommends that optional
performance-based and limit state procedures and component cyclic
testing procedures be incorporated into the RMI-developed
specification. Compliance with these procedures will demonstrate
that the storage racks have the capacity to resist maximum
considered earthquake ground motions without collapse. It also is
recommended that regulatory bodies periodically review the quality
assurance programs of stores and implement any regulations needed
to satisfy life-safety concerns that relate to the securing of rack
contents and rack maintenance and use.
Lifelines (e.g., communication, electric power, liquid fuels,
natural gas, transportation, water and sewer systems, etc.) are
presently being sited in "utility or transportation corridors" to
reduce their right-of-way environmental, aesthetic, and cost
impacts on the community and on land use. The individual lifelines
are usually constructed or modified at different time periods,
resulting in their being built to different standards and in
different siting criteria being applied to different segments of an
individual lifeline or to different lifelines that provide similar
functions. Presently, the siting review usually does not consider
the impact of the proximity or collocation of one lifeline upon the
risk to or vulnerability of other lifelines from natural or manmade
hazards or disasters, either because the other lifelines have not
yet been installed or because such a consideration has not been
identified as a factor in the siting evaluation. In August 1988, a
train derailment in northern California also damaged a petroleum
pipeline which was buried along the railroad right-of-way. The
result was a spill of the pipeline fluids in addition to the
derailment (but no significant loss of property and no injuries to
or casualties). When another derailment in San Bernardino occurred
in May l989, which resulted in severe property damage and the loss
of life, the Office of the Fire Marshall also responded to see if
the derailment had impacted a petroleum products pipeline that was
buried along the railroad right-of-way. It was decided that the
pipeline was not damaged, and the fire and safety personnel turned
over the site to the railroad to allow them to clean up the site.
About a week later the pipeline ruptured and the resulting fire
caused considerable property damage and loss of life. The
subsequent investigations concluded that the pipeline may have been
damaged during the derailment, but that the most probable cause of
its damage was the derailment clean up operations. In a similar
sense, communication lines along a highway bridge would be
vulnerable to failure if the bridge were to displace or fail during
a disaster event. In fact, frequently highway bridges and
overpasses are used to route other lifelines, such as
communications and pipelines, over causeways and water bodies. Such
lifelines can be damaged by failure of the superstructure, bridge
foundation movement, or ground deformation along the approaches to
the bridge. Settlement and lateral displacement adjacent to
abutments have been especially troublesome because such movements
tend to impose deformations on the lifelines where they are locally
constrained at the attachment or penetration of the abutment. There
are many such examples of lifeline interdependency that occurred
during the 1989 Loma Prieta earthquake. In response to these types
of situations, FEMA is focusing attention on the use of such
corridors, and they initiated this study to examine the impacts of
siting multiple lifeline systems in confined and at-risk areas. The
overall FEMA project goals are to develop, for multiple lifeline
systems in confined and at-risk areas, a managerial tool that can
be used to increase the understanding of the lifeline systems'
vulnerabilities and to help identify potential mitigation
approaches that could be used to reduce those vulnerabilities. The
goals also are to identify methods to enhance the transfer of the
resulting information to lifeline system providers, designers,
builders, managers, operators, users, and regulators. To provide a
specific example of how the managerial tool can be used, it was
decided that the methods should be applied to the lifelines in the
Cajon Pass, California, for an assumed earthquake event at the
Pass. The purpose of this report is to provide an inventory of the
major lifeline systems in the Cajon Pass and the earthquake and
geologic analysis tools available to identify and define the level
of seismic risk to those lifelines.
