In the aftermath of 2017’s historic hurricanes and wildfires, Congress provided one-time funding of nearly  $140 billion.1 With the increasing severity and frequency of natural disasters, policymakers are looking for ways to control costs by investing in mitigation activities—actions that reduce risk to lives and property—before a disaster happens.2

Research shows that mitigation investments reduce costs for disaster response and recovery: Taxpayers save an average of $6 for every $1 the federal government spends on activities such as elevating homes, strengthening or retrofitting infrastructure, and purchasing flood-prone properties for removal.3 In response to the 2017 hurricane season, Federal Emergency Management Agency (FEMA) Administrator Brock Long told the U.S. House Transportation and Infrastructure Committee, “I cannot overstate the importance of focusing on investing in mitigation before a disaster strikes,” and noted that “building more resilient communities is the best way to reduce risks to people, property, and taxpayer dollars.”4

However, most federal mitigation investments are made after a disaster occurs, and very little data on state funding for such programs are publicly available.5 All levels of government need a more comprehensive understanding of federal and state investments if they are going to better target funding and decide whether new incentives are necessary to encourage mitigation activities.

Federal spending

The federal government funds mitigation programs primarily via FEMA, although support also comes from programs at other agencies. These include the Department of Housing and Urban Development’s Community Development Block Grant Disaster Recovery Program, the Small Business Administration’s Disaster Loan Program, the Department of Commerce’s Coastal Zone Management Administration Awards, and the Department of Agriculture’s State Fire Assistance Program, among others. Federal agencies also implement  their own mitigation measures directly, such as construction and maintenance of flood-control systems by the U.S. Army Corps of Engineers.6

The most complete publicly available mitigation spending data are for FEMA’s three grant programs—the Hazard Mitigation Grant Program (HMGP), Pre-Disaster Mitigation (PDM) Grant Program, and Flood Mitigation Assistance (FMA) Grant Program—but total figures across the federal government remain unknown.7

Through its mitigation grant programs, FEMA provides financial assistance to state and local governments to engage in mitigation activities, such as seismic retrofits and construction of safe rooms and flood-resistant bridges.8 Total funding for the programs from 2007 to 2016 was $8.3 billion, after adjusting for inflation.9 (See Figure 1.) HMGP was the largest of the three at $6.9 billion (84 percent of the total), but funding from the program is available only after a major federal disaster declaration, meaning the president has determined that the magnitude of the disaster has exceeded the state’s capacity to effectively respond.10 Although the FMA and PDM programs are far smaller, spending $844 million and $512 million, respectively, over the period, grants from these programs are awarded without a federal disaster declaration.11

FEMA’s grant programs also differ in the way they are designed and awarded:

  • The Hazard Mitigation Grant Program aims to reduce loss of life and property damage from future natural disasters by providing funding to state and local governments for mitigation projects after a major disaster declaration. The amount of funding a state receives for a declaration is 7.5 to 15 percent of the total disaster aid that FEMA grants the state for that disaster. For states with enhanced hazard mitigation plans, the maximum rises to 20 percent. In either case, the amount of disaster aid used to calculate the percentage is capped at $35.3 billion. States are obligated to pay a 25 percent cost share to receive funding.12
  • The Pre-Disaster Mitigation Grant Program provides grants to state and local governments to reduce overall risk to individuals and property from future disasters. All states receive some funding annually through a formula, and states wanting additional money must submit proposals to a competitive review process.13 Both categories have a required 25 percent cost share.14
  • The Flood Mitigation Assistance Grant Program aims to reduce or eliminate claims under the National Flood Insurance Program by providing competitive grants to state and local governments to develop plans and undertake projects to address flood risks.15  Depending on the type of project, FEMA will cover 75 to 100 percent of state costs.16
Mitigation Funding Through FEMA’s Public Assistance Program

A substantial amount of FEMA spending on natural hazard mitigation also occurs through the Public Assistance (PA) grant program, which provides funding to state and local governments to clear debris and rebuild public infrastructure. However, section 406(e) of the Robert T. Stafford Disaster Relief and Emergency Assistance Act allows some PA funding to be used at FEMA’s discretion for certain mitigation projects involving the repair, replacement, or restoration of disaster-damaged public facilities.17

Spending data for PA mitigation assistance are not publicly available, but the Congressional Research Service has previously reported that obligations totaled $3.7 billion from federal fiscal years 2000 to 2013, with a high of roughly $2 billion related to Superstorm Sandy in 2013 and a low of $15 million in 2002.18

HMGP funding, which accounts for most of the money available through FEMA mitigation grants, is heavily influenced by the episodic nature of disaster events and so varies greatly over time. The program received substantial increases in the aftermath of hurricanes Ike and Irene and Superstorm Sandy. From 2007 to 2016, FMA spending also fluctuated for various reasons, such as delays in the congressional appropriations process.19 (See Figure 2.)

Federal mitigation aid differs across states

All 50 states and the District of Columbia received at least some financial support from FEMA’s mitigation programs from 2007 to 2016, but the amount and type varies. During that period, funding to the states ranged from $7 million in Wyoming to $1.4 billion in New York, and the District received $6 million.

Forty-three states received the largest share of their FEMA mitigation grants through HMGP, ranging from 99 percent in Iowa to 41 percent in North Carolina.20 The remaining states—Arizona, Delaware, Idaho, Montana, Nevada, Utah, and Wyoming—and the District received most of theirs through PDM. (See Figure 3.)

Many factors affect the mix of funding in each state, including the type, frequency, and severity of natural disasters, and whether the president declares a major disaster; the different federal program structures; and state and local government decisions about which and how much aid to pursue. 

State spending

Data on how and to what extent the states and the District invest in mitigation are limited. To fill this information gap, The Pew Charitable Trusts collected data on states’ natural disaster-related spending for state fiscal 2012 through 2016.21 (For a detailed description of the methodology, see The Pew Charitable Trusts, “What We Don't Know About State Spending on Natural Disasters Could Cost Us,” June 2018.) Twenty-three states responded to Pew’s survey.22 Of those, eight provided sufficient data to support an analysis of the share of total reported disaster spending used for states’ own mitigation programs and federal cost shares spending related to federal mitigation programs less reimbursements received from the federal government).23  From 2012 to 2016, that share varied from 33 percent in Arkansas to zero in Maryland and Wyoming.24 (See Table 1.) 

Most of the states that responded to Pew’s survey reported that the bulk of their mitigation spending was for cost shares for federal programs, such as HMGP, and some indicated no state-funded mitigation efforts. However, five states reported investments in hazard mitigation other than for federal programs during the five years examined. For example, Iowa spent $49 million on municipal mitigation projects through the state’s Flood Mitigation Board. (See Table 2.)


In an era of increasingly expensive natural disasters, efforts to manage growing costs through mitigation activities are likely to increase. And although neither the federal government nor the states comprehensively track their mitigation spending, Pew’s analysis of the limited data available shows that most of FEMA’s investments are  made after a disaster occurs and that the bulk of spending by the states studied was for cost shares for federal programs. 

Because the federal government and states do not know how much they spend on mitigation in total, they lack the information to accurately compare proactive investments with post-disaster response and recovery expenditures. All levels of government need a more comprehensive understanding of federal and state investments in order to better target funding to help manage the growing costs of catastrophic events. 

External reviewers

This project benefited from the insights and expertise of two external reviewers: Keith Porter, research professor at the University of Colorado, Boulder, and Jared Brown, analyst in emergency management and homeland security policy at the Congressional Research Service. Although they reviewed the analysis, neither they nor their  organizations necessarily endorse its findings or conclusions.

  2. The Federal Emergency Management Agency is considering several options to increase mitigation measures across levels of government. For example, the agency launched its “Mitigation Investment Moonshot” in 2017, with the goal of quadrupling mitigation spending by federal, state, local, and tribal governments; corporations; nonprofits; and private foundations by 2022. Additionally, Congress included a provision in its 2018 bipartisan budget agreement allowing the president to increase the federal government’s share of recovery costs from 75 to 85 percent for states that have invested in mitigation.

  6. Other examples include the National Oceanic and Atmospheric Administration, which provides preparedness, warning, and response information about storms, tsunamis, volcanoes, and wildfires, and the U.S. Geological Survey, which conducts hazard mitigation-focused research to inform policymakers’ decisions, including studies of coastal and marine geology, earthquakes, and volcanology. 
  7. FEMA, the Government Accountability Office (GAO), and the National Institute of Building Sciences have undertaken efforts to identify total federal hazard mitigation investments that have each yielded different findings. See Federal Emergency Management Agency, “Managing Natural Disaster Risk: FEMA’s Strategic Direction for the National Flood Insurance Program and National Mitigation Investment Strategy” (2018),, Government Accountability Office, “Federal Disaster Assistance” (2016),, and National Institute of Building Sciences, “Natural Hazard Mitigation Saves: 2017 Interim Report” (2018), GAO recommended that the Mitigation Framework Leadership Group—an intergovernmental coordinating body created in part to help align mitigation efforts across levels of government—identify all federal mitigation programs and activities as part of a federal investment strategy. See Government Accountability Office, “Hurricane Sandy: An Investment Strategy Could Help the Federal Government Enhance National Resilience for Future Disasters” (2015),
  8. U.S. territories and federally recognized tribes may also take advantage of FEMA mitigation grant programs. Additionally, the HMGP provides funding to nonprofit organizations. 
  9. Pew’s analysis of inflation-adjusted data from the Federal Emergency Management Agency, “Hazard Mitigation Assistance Projects,” accessed April 25, 2018,; U.S. Department of Commerce’s Bureau of Economic Analysis, “Current-Dollar and ‘Real’ GDP,” accessed April 27, 2018, All federal spending figures reflect obligations unless otherwise noted and are presented according to the date that FEMA allocated funds to a project; they do not reflect total funding provided by Congress. Although other types of spending data for FEMA’s mitigation grant programs exist (e.g., appropriations and outlays), Pew used obligations information because they were the only data that allowed for a state-by-state breakdown.

  19. Jason Kennedy (Flood Mitigation Assistance Grant Program lead, Federal Insurance and Mitigation Administration, Federal Emergency Management Agency), email to The Pew Charitable Trusts, July 11, 2018. The Consolidated and Further Continuing Appropriations Act of 2013 did not authorize FMA funding for fiscal year 2013 until March, six months after the start of the fiscal year on Oct. 1, 2012. This interruption delayed the awarding of fiscal 2013 FMA funds until fiscal 2014. Additionally, the Repetitive Flood Claims and Severe Repetitive Loss programs did not receive funding after fiscal 2012 because they ended that year. Instead, aspects of both programs were merged into the FMA program as part of the Biggert-Waters Flood Insurance Reform Act of 2012. 
  20. Oregon and North Carolina each received the largest share of their funding through HMGP (47 percent and 41.1 percent, respectively); however, the sum of PDM and FMA was greater than HMGP in both states. 
  21. Pew surveyed state emergency management offices for information on state program spending (expenditures for state-funded programs and state disaster declarations), federally related spending (expenditures required to receive certain federal grants), federal reimbursements received (federal funding provided to states to refund certain federally related spending), and breakdowns of spending by disaster phase (mitigation, preparedness, response, and recovery). See The Pew Charitable Trusts, “What We Don’t Know About State Spending on Natural Disasters Could Cost Us.” 
  22. States that reported data: Alabama, Alaska, Arizona, Arkansas, Colorado, Connecticut, Delaware, Florida, Georgia, Idaho, Iowa, Kansas, Maryland, Michigan, North Dakota, Ohio, Oregon, Pennsylvania, Utah, Virginia, Washington, Wisconsin, and Wyoming. 
  23. Pew researchers provided written questions to states to clarify ambiguous data and followed up with one or more interview sessions to further refine specific spending figures and descriptions of those figures used in this brief. The eight states were Arizona, Arkansas, Delaware, Maryland, Ohio, Pennsylvania, Wisconsin, and Wyoming. Individual data points used in this brief from the other 15 responding states were verified before publication. Following its original survey response, Arizona was able to identify an additional $2,555,559 in state spending on mitigation measures during the five-year study period.

What We Don't Know About State Spending on Natural Disasters Could Cost Us

Quick View

Natural disaster assistance—helping communities be ready for and recover from events such as storms, earthquakes, and wildfires—involves an array of players from the public, for-profit, and nonprofit sectors. Central to those efforts is a complex intergovernmental partnership that is under stress from the increasing frequency and severity of losses and from budget constraints at all levels of government.
