Book Description
Floodplain maps serve as the basis for determining whether homes or buildings require flood insurance under the National Flood Insurance Program run by the Federal Emergency Management Agency (FEMA). Approximately $650 billion in insured assets are now covered under the program. FEMA is modernizing floodplain maps to better serve the program. However, concerns have been raised as to the adequacy of the base map information available to support floodplain map modernization. Elevation Data for Floodplain Mapping shows that there is sufficient two-dimensional base map imagery to meet FEMA's flood map modernization goals, but that the three-dimensional base elevation data that are needed to determine whether a building should have flood insurance are not adequate. This book makes recommendations for a new national digital elevation data collection program to redress the inadequacy. Policy makers; property insurance professionals; federal, local, and state governments; and others concerned with natural disaster prevention and preparedness will find this book of interest.

Book Description
Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps portray the height and extent to which flooding is expected to occur, and they form the basis for setting flood insurance premiums and regulating development in the floodplain. As such, they are an important tool for individuals, businesses, communities, and government agencies to understand and deal with flood hazard and flood risk. Improving map accuracy is therefore not an academic question-better maps help everyone. Making and maintaining an accurate flood map is neither simple nor inexpensive. Even after an investment of more than $1 billion to take flood maps into the digital world, only 21 percent of the population has maps that meet or exceed national flood hazard data quality thresholds. Even when floodplains are mapped with high accuracy, land development and natural changes to the landscape or hydrologic systems create the need for continuous map maintenance and updates. Mapping the Zone examines the factors that affect flood map accuracy, assesses the benefits and costs of more accurate flood maps, and recommends ways to improve flood mapping, communication, and management of flood-related data.

Book Description
This open access book addresses the way in which urban and urbanizing regions profoundly impact and are impacted by climate change. The editors and authors show why cities must wage simultaneous battles to curb global climate change trends while adapting and transforming to address local climate impacts. This book addresses how cities develop anticipatory and long-range planning capacities for more resilient futures, earnest collaboration across disciplines, and radical reconfigurations of the power regimes that have institutionalized the disenfranchisement of minority groups. Although planning processes consider visions for the future, the editors highlight a more ambitious long-term positive visioning approach that accounts for unpredictability, system dynamics and equity in decision-making. This volume brings the science of urban transformation together with practices of professionals who govern and manage our social, ecological and technological systems to design processes by which cities may achieve resilient urban futures in the face of climate change.

Book Description
Alluvial fans are gently sloping, fan-shaped landforms common at the base of mountain ranges in arid and semiarid regions such as the American West. Floods on alluvial fans, although characterized by relatively shallow depths, strike with little if any warning, can travel at extremely high velocities, and can carry a tremendous amount of sediment and debris. Such flooding presents unique problems to federal and state planners in terms of quantifying flood hazards, predicting the magnitude at which those hazards can be expected at a particular location, and devising reliable mitigation strategies. Alluvial Fan Flooding attempts to improve our capability to determine whether areas are subject to alluvial fan flooding and provides a practical perspective on how to make such a determination. The book presents criteria for determining whether an area is subject to flooding and provides examples of applying the definition and criteria to real situations in Arizona, California, New Mexico, Utah, and elsewhere. The volume also contains recommendations for the Federal Emergency Management Agency, which is primarily responsible for floodplain mapping, and for state and local decisionmakers involved in flood hazard reduction.

Book Description
FEMA's Hazard Mitigation Grant Program is a powerful resource in the combined effort by Federal, State, and local government, as well as private industry and homeowners, to end the cycle of repetitive disaster damage. The Robert T. Stafford Disaster Relief and Emergency Assistance Act was passed on November 23, 1988, amending Public Law 93-288, the Disaster Relief Act of 1974. The Stafford Act included Section 404, which established the Hazard Mitigation Grant Program. In 1993, the Hazard Mitigation and Relocation Act amended Section 404 to increase the amount of HMGP funds available and the cost-share to 75 percent Federal. This amendment also encouraged the use of property acquisition and other non-structural flood mitigation measures. In an effort to streamline HMGP delivery, FEMA encourages States to develop their mitigation programs before disaster strikes. States are adopting a more active HMGP management role. Increased capabilities may include: Conducting comprehensive all-hazard mitigation planning prior to disaster events; Providing applicants technical assistance on sound mitigation techniques and hazard mitigation policy and procedures; Coordinating mitigation programs through interagency teams or councils. Conducting benefit-cost analyses; and Preparing National Environmental Policy Act reviews for FEMA approval. States that integrate the HMGP with their frequently updated State Administrative and Hazard Mitigation Plans will create cohesive and effective approaches to loss reduction. This type of coordinated approach minimizes the distinction between “predisaster” and “post-disaster” time periods, and instead produces an ongoing mitigation effort. Hazard mitigation is any sustained action taken to reduce or eliminate long-term risk to people and property from natural hazards and their effects. A key purpose of the HMGP is to ensure that the opportunity to take critical mitigation measures to protect life and property from future disasters is not lost during the recovery and reconstruction process following a disaster. Program grant funds available under Section 404 of the Stafford Act provide States with the incentive and capability to implement mitigation measures that previously may have been infeasible. The purpose of this Desk Reference is to: Provide comprehensive information about FEMA's Hazard Mitigation Grant Program (HMGP); Increase awareness of the HMGP as an integral part of statewide hazard mitigation efforts; and Encourage deeper commitments and increased responsibilities on the part of all States and communities to reduce damage and losses from natural disasters. This Desk Reference is organized to simplify program information and assist the reader with practical guidance for successful participation in the program. Lists of program-related acronyms and definitions are included, along with appendices that amplify selected aspects of the HMGP. This Desk Reference is organized into 14 sections, each of which presents a major HMGP subject area. In each section, information is presented on the right side of the page. In several sections, job aids containing supplemental material are provided. The job aids for each section can be found at the end of the section. At the front of each section, there is a detailed table of contents to help you locate specific information.
