In the two decades since Hurricane Katrina, major policy reforms strengthened disaster response at every level, bolstering the capacity of the Federal Emergency Management Agency (FEMA) and setting higher standards that have kept communities safer. While there was still much work to be done, the nation was making strides toward a more resilient future.
That progress is at risk today as the Trump administration has cut staff, rolled back many of these advances, and left FEMA severely weakened—even threatening to dismantle the agency entirely.
August 29, 2025, marks the 20th anniversary of Hurricane Katrina making landfall in Louisiana. The disaster that followed remains emblematic of environmental injustice and failure at all levels of government. It resulted in more than $200 billion in costs and at least 1,400 deaths. It was one of the most devastating Atlantic hurricanes in history.
Hurricane Katrina disproportionately harmed low-income communities and communities of color. Pre-existing and systemic inequalities in flood risk, poverty, and access to resources set the scene for a grossly inadequate response that highlighted how disasters are most devastating for those in society who are lowest on the socioeconomic ladder.
NRDC’s senior director of climate adaptation, Dr. Adelle Thomas, joins us to discuss just how Hurricane Katrina was a blaring wake-up call to the nation—highlighting the urgent need for environmental justice and disaster response reforms.
In the aftermath, Hurricane Katrina—along with Harvey, Irma, Maria, Sandy, and many other storms—played a role in shaping risk-reduction strategies: After all, preparing ahead of time is the best way to minimize the need for billions of dollars in disaster response. Making sure a highway or a hospital isn’t built in a floodplain just makes sense, and it makes more sense now than ever before as climate-fueled storms become turbocharged. Many policy reforms were hard-won, driven by the painful lessons these storms left behind in communities across the country.
Overview of federal policy reforms post-Katrina
- A direct legislative response to the failures in 2005, the Post-Katrina Emergency Management Reform Act addressed coordination, leadership, and responsiveness. Provisions included:
- Making FEMA a distinct entity within the Department of Homeland Security with the mission to “reduce the loss of life and property and protect the nation from all hazards by leading and supporting the nation in a risk-based, comprehensive emergency management system of preparedness, protection, response, recovery, and mitigation.”
- Setting eligibility criteria for the FEMA administrator.
- Prohibiting discrimination in disaster aid based on disability and English proficiency.
- Congress required FEMA to include future sea level rise in the nation’s flood risk maps.
- FEMA required state disaster risk reduction plans to consider climate change.
- Federal Flood Risk Management Standards required climate-informed flood standards for federally funded projects. Though introduced nearly a decade after Katrina, they built on lessons from the rebuilding efforts.
- In 2020, FEMA launched its flagship hazard mitigation program, Building Resilient Infrastructure and Communities (BRIC), for reducing risk before the next disaster strikes, funding vital projects to save lives, infrastructure, and taxpayer dollars.
- Since 2020, BRIC has directed more than $1 billion annually to climate-resilient projects like floodplain restoration, wildfire mitigation, and upgrades to vulnerable infrastructure.
- Evolving policy changes redefined and interpreted FEMA’s existing authorities with regard to equity, including the application of federal civil rights law.
- FEMA established the Civil Rights Advisory Group to promote equitable vaccine policies in distribution of Stafford Act assistance and in the operations of grantees.
- NOAA and the National Weather Service invested in satellites and modeling post-Katrina, which allowed for significantly more accurate weather forecasting.
- Agencies advanced more efficient recovery through open and accessible government data.
20 years’ worth of hard-won lessons forgotten
The policy changes that followed Hurricane Katrina and the additional staff capacities were hard-won. They took years to develop and implement and, in many cases, that work is still ongoing. Rolling back those well-established policies, programs, and protocols not only undermines our national preparedness, but it disrespects the memory of those who lost their lives, the resilience of survivors, and the tireless efforts of communities, advocates, and public officials who fought to make us all safer. Too often, it takes a major disaster to force meaningful change. We cannot afford to let shortsighted policy decisions become the source of the next one.
The Trump administration has made major cuts to FEMA, which is critically important for preparing for, responding to, and recovering from disasters like hurricanes, floods, wildfires, and other man-made and climate-influenced disasters.
The president and U.S. Department of Homeland Security Secretary Kristi Noem repeatedly talk about getting rid of FEMA entirely. And the agency’s acting administrator, Cameron Hamilton, took an ax to FEMA’s staff, programs, and basic functions before being fired after saying, “I do not believe it is in the best interests of the American people to eliminate the Federal Emergency Management Agency.”
The following is a list of rollbacks by this administration
- Substantial staff and program reductions at FEMA, with leadership signaling intentions to either shrink or eliminate FEMA altogether, are crippling national disaster preparedness capacity.
- FEMA’s interim 2025 leader, fired after testifying that it shouldn’t be abolished, lamented politically driven constraints undermining the agency’s mission.
- Real‑world consequences: The 2025 Texas flood disaster response was reportedly worsened by FEMA’s diminished capacity: Grant award delays, halted training, and a reluctance to engage prevented a timely response and recovery.
- The Trump administration’s revocation of the Federal Flood Risk Management Standard for federally funded projects heightens repeated flood risk.
- The National Flood Insurance Program, saddled with $23 billion in debt from Katrina and never fully reformed, was further compromised as Trump vowed to “eliminate FEMA” and downsize federal flood programs.
- Public statements from Secretary Noem and others suggesting that FEMA would be eliminated—shifting disaster leadership to the states—have created confusion and delayed disaster planning.
- Thousands of proposals totaling billions of dollars for communities across the country to prepare for the next disaster were abruptly cancelled.
- On August 7, a preliminary injunction was granted against FEMA, stopping the agency from diverting BRIC funding, but projects remain in limbo as litigation continues.
- The administration claims that it wants to increase states’ level of responsibility for disasters and emergency management, but its actions are instead actively diminishing the capacity of emergency managers and first responders across the country.
- Notices of Funding Opportunity for preparedness grants—key sources of funding for state emergency management capabilities—were delayed for months compared to previous years, leaving states uncertain as to whether they could continue to fund critical operations.
- FEMA staff were abruptly reassigned to immigration enforcement, at a time when agency staffing is already down by one-third and states and localities are looking to the federal government for support with ongoing disasters.
- Grants and contracts were slowed by new Department of Homeland Security review requirements, preventing disaster survivors from accessing FEMA hotlines for days after the Texas floods and delaying assistance to communities rebuilding after Hurricane Helene.
Twenty years later, Hurricane Katrina still offers hard lessons. The environmental hazards, racial inequities, and infrastructure failures it exposed continue to highlight the urgent need for reforms that remain unfinished. The Trump administration’s dismantling of FEMA, including the rollback of protections and diminished readiness, makes communities more vulnerable to the next disaster. This anniversary, we should reaffirm the need for adequate federal resources to respond to a disaster and re-establish programs that help communities prepare before weather-related disasters happen.
The next extreme weather event could happen at any time. We are officially in hurricane season. Wildfires are already burning in several western states, and severe flooding has devastated communities from West Texas to North Carolina. Many more disasters, driven by our rapidly warming climate, are going to happen. We know that. It’s just a question of where and when. We must strengthen the federal agencies that can address extreme weather threats to our country.
