- The HAZUS-MH Hurricane Wind Model is an improvement over existing loss estimation models because it uses a wind hazard-load-damage-loss framework. New in HAZUS-MH MR3 Flood Model: Data: Commercial data updated to Dun & Bradstreet 2006; Building valuations updated to R.S. Means 2006, and; Building counts based on census housing unit counts for RES1 (single-family dwellings) and RES2 (manufactured housing) instead of calculated building counts. Methodology: Storms for 2004 and 2005 added to the historic storms database and updates made for several existing historic storms; Use of NOAA hurricane advisory data to model storms restored with an adjustment feature for calculating building damage and loss; New probabilistic storm set reflecting updates to the Holland pressure profile model and filling model; Updated wind field model for user-defined storms, and; New vulnerability functions to permit calculation of additional losses to manufactured housing due to tree blowdown.
- The flood loss estimation methodology consists of two modules that carry out basic analytical processes: flood hazard analysis and flood loss estimation analysis. The flood hazard analysis module uses characteristics, such as frequency, discharge, and ground elevation to estimate flood depth, flood elevation, and flow velocity. The flood loss estimation module calculates physical damage and economic loss from the results of the hazard analysis. New in HAZUS-MH MR3 Flood Model: Data: Commercial data updated to Dun & Bradstreet 2006; Building valuations updated to R.S. Means 2006, and; Building counts based on census housing unit counts for RES1 (single-family dwellings) and RES2 (manufactured housing) instead of calculated building counts. Methodology: User-supplied flood maps and flood depth grids import into the “quick look” and “enhanced quick look” functions; Optimized building analysis, and; Revised hazard menu graphic user interface.
- Mitigation is the effort to reduce loss of life and property by lessening the impact of disasters. Effective mitigation measures can break the cycle of disaster damage, reconstruction, and repeated damage. FEMA’s Federal Insurance and Mitigation Administration implements a variety of programs authorized by Congress that cover the full range of natural hazards. Mitigation efforts provide value to the American people by (1) creating safer communities by reducing loss of life and property, (2) enabling individuals to recover more rapidly from flood and other disasters, and (3) lessening the financial impact on the Treasury, States, Tribes, and communities.
- Mitigation is the effort to reduce the loss of life and property by lessening the impact of disasters. A recent study by the Multihazard Mitigation Council shows that each dollar spent on mitigation saves an average of four dollars. FEMA’s Federal Insurance and Mitigation Administration (FIMA) implements numerous Congressionally-authorized programs that address the effects of natural hazards through mitigation activities.
Following a disaster, FEMA’s mitigation programs play a critical role developing and integrating disaster operations policies, procedures, and training under the National Response Plan. The Regional and Disaster Support Branch within the Federal Insurance and Mitigation Administration acts as the coordination point for mitigation disaster operations and activities.
Fiscal Year (FY) 2008 Pre-Disaster Mitigation Program Guidance – The Pre-Disaster Mitigation Program Guidance (PDM) grant program assist States and communities to reach a higher level of risk management and risk reduction through hazard mitigation planning and the implementation of mitigation projects and activities prior to a disaster event.

- Returning to your fire-damaged home will undoubtedly be an emotional experience. But as you go about the task of rebuilding, there are many ways to rebuild safer, stronger, smarter and more resilient to wildfires. The Federal Emergency Management Agency (FEMA) has teamed with Firewise Communities, the Federal Alliance for Safe Housing, and the Institute for Business and Home Safety to provide this resource for rebuilding after a fire.
- FEMA proposes to provide Public Assistance grant funding to repair flood damage to Stateline Road in unincorporated Greenlee County, Arizona, which occurred in the February 2005 winter storms. In accordance with the National Environmental Policy Act, FEMA has prepared an Environmental Assessment to evaluate potential impacts of the proposed project on the human and natural environment.

- This handout version of the report presents the findings of a FEMA validation study of the HAZUS-MH Riverine Flood Model. It is based on a loss event that occurred in St. George, Utah, on January 9-11, 2005, which took one life and damaged 28 homes along the Santa Clara River. The validation study assessed the performance of the HAZUS loss model along both the Santa Clara and Virgin Rivers in the St. George, Utah, area. HAZUS is a very useful tool to help model flood boundaries and estimate economic and social losses. Provided accurate event flow discharges are available through accurate forecasting, at gages or other known locations along the reach of interest, HAZUS can help provide timely flood boundary and loss-estimate information before, during, or after a flood.
- The Federal Emergency Management Agency (FEMA), along with the National Institute of Building Sciences (NIBS), is pleased to announce the latest release of HAZUS-MH. In this newest version MR3, the Flood Model will run building analyses faster and users will import user-supplied flood maps and flood depth grids. The Hurricane Model boasts an updated and revised historical database that includes storms from 2004 and 2005. New vulnerability functions will permit calculation of additional losses to manufactured housing due to tree blowdown. Changes to the Earthquake Model include adjustable population distribution parameters in the casualty module and the elimination of partial ignitions in the fire-following module.
- The CHUG (Central HAZUS Users Group) provides a means of collaboration between HAZUS-MH users within FEMA Region 5. The main goal of the CHUG is to maximize the potential of HAZUS-MH within the region. Sharing the successes and challenges between users helps bring the entire region together in planning for natural disasters.
HAZUS User Groups Success Story: ORHUG, Geologic Hazards and Future Earthquake Damage and Loss Estimates for Six Counties In the Mid/Southern Willamette Valley, OregonOregon Department of Geology and Mineral Studies (DOGAMI) partnered with Oregon Emergency Management (OEM) and the Oregon Natural Hazards Workgroup (ONHW) at the University of Oregon to assist local communities with their Pre-Disaster Mitigation plans. As of April 2006, 18 of Oregon's 36 counties have FEMA-approved natural hazard mitigation plans. The goal of the DOGAMI-ONHW-OEM partnership is to assist all remaining counties in the state to develop plans by 2010 utilizing this approach.
HAZUS User Groups Success Story: NVHUG, Loss-Estimation Modeling of Earthquake Scenarios for Each County in NevadaWith the support of the Nevada Division of Emergency Management the Nevada Bureau of Mines and Geology (NBMG) conducted a project to model the potential earthquake loss in each county in the state of Nevada using HAZUS-MH. Potential earthquake faults that are located near each County seat where selected as the basis for each County HAZUS-MH model. The results generated by HAZUS-MH for this project, including statistics and maps, have been made available to the Nevada HAZUS User Group and to the general public via the Web.
- To help Hawaii's disaster managers better prepare for and respond to potentially devastating earthquakes, the Pacific Disaster Center (PDC) in collaboration with Hawaii State Civil Defense and the Hawaii State Earthquake Advisory Committee (HSEAC) has created the Hawaii HAZUS Atlas (HHA). the HHA is a web-based catalog of 20 "plausible" hypothetical earthquakes based on historical events located in (and around) Maui and Hawaii Counties. The HHA contains loss estimation data and analyses based on HAZUS scenarios. With HHA, communities can use HAZUS results to assist in disaster planning before, during, and after a destructive earthquake.
- The mission of the 3RiversHUG is to offer a forum for southwestern Pennsylvania public, private, and academic organizations that use HAZUS-MH software and related technologies to develop public policy and programs for building disaster-resistant communities. This group began as Project Leader, Dr. Jamie Mitchem, and his colleague Dr. Thomas Mueller at California University of Pennsylvania realized the need for comprehensive planning for flood mitigation activities in southwestern Pennsylvania.
Programmatic Environmental Assessment for HMGP Program Exception for the States of Louisiana and Mississippi(FEMA) has prepared a draft Programmatic Environmental Assessment (PEA) to address the potential impacts to the human and natural environment resulting from FEMA’s proposed implementation of a limited exception allowing it to retroactively fund initiated and completed activities eligible under FEMA’s Hazard Mitigation Grant Program (HMGP) in Hurricane Katrina and Rita impacted areas of Mississippi and Louisiana. As required by the National Environmental Policy Act (NEPA) and FEMA’s regulations implementing NEPA, the agency has prepared a draft PEA to evaluate the potential impacts to the environment of alternatives for implementing this HMGP program exception.
