Hazard mitigation means taking smart and affordable actions to lower the chance of people, homes, and important structures being harmed by disasters.
These actions can and should happen before a disaster strikes, and they are very important. After disasters, repairs often just bring things back to the way they were before. But when hazard mitigation is used, we can rebuild in ways that make buildings and communities stronger, safer, and better prepared.
Hazard mitigation is the first step in dealing with disasters, followed by being prepared, responding, and recovering. Even though people sometimes ignore it, hazard mitigation is very important because it works to reduce risks and stop the costly cycle of repeated damage. This is starting to change. New York City has made a big shift toward using mitigation, the key step that can help prevent this cycle and lower losses after a disaster. Experts estimate that for every $1 spent on hazard mitigation, about $6 is saved over time.
The NYC's Risk Landscape: A Guide to Hazard Mitigation is based on the 2024 Hazard Mitigation Plan website and focuses on the hazards that pose a risk to New York City and includes information on how the City approaches risk management in a user-friendly and accessible format.
What is NYC's Hazard Mitigation Plan?
New York City's Hazard Mitigation Plan lists different events (emergencies, disasters, or hazards) that could harm the city and explains what City agencies are doing to reduce their impact.
To get FEMA funding for hazard mitigation after a disaster, the plan must be updated every five years. In March 2009, NYC Emergency Management finished the first Hazard Mitigation Plan to help make the city stronger against hazards. Five years later, they worked with the Department of City Planning and the Mayor’s Office of Resiliency to update the plan in 2014. After that, yearly updates came out in 2015, 2016, and 2017

In 2019, NYC Emergency Management created the five-year update as a website. This made New York City the first in the region to have an online FEMA-required hazard mitigation plan. The site explains the hazards that could affect the city, the risks to people and infrastructure, and strategies to reduce damage.
The website includes:
-
Important features of the city’s environment that make it at risk
-
Risk assessments for nine hazards, showing how likely they are, where they might happen, and past events
-
Best practices and strategies led by the City to manage each hazard
What hazards are included in the plan?
Hazards in the plan include: coastal erosion, coastal storms, disease outbreaks, drought, earthquakes, extreme temperatures, flooding, thunderstorms, tornadoes, windstorms, wildfire, winter storms, chemical, biological, radiological, and nuclear (CBRN), cyber threats, and infrastructure failures.
What is New York City doing to make it more resilient to hazards?
The plan lists both current and possible future actions to limit the effects of a major disaster on the city’s people, economy, buildings, and infrastructure. You can see all the actions and an interactive map under the “Mitigation Strategy” section of the website.
Is a hazard mitigation plan required by law?
Yes. The Robert T. Stafford Disaster Relief and Emergency Assistance Act, signed in 1988, allows the federal government to help states and cities prepare for, respond to, and recover from disasters.
In 2000, the Disaster Mitigation Act (DMA 2000) updated the law to stress the need for planning before disasters happen. It requires states, local governments, and Tribal governments to work together on mitigation planning. To get FEMA hazard mitigation funding, a community must have an approved plan.
Record Rain in NYC: The Impacts of Post-Tropical Cyclone Ida - Damage report
The
Record Rain in NYC report is the culmination of storm impact analyses conducted following Post-Tropical Cyclone Ida (PTC Ida), created by combining many disparate datasets of damage indicators that were collected the days, weeks, and months following the event. NYC Emergency Management's Resiliency and Recovery Planning Unit aims to use this analysis to better understand the city’s risk to inland flooding, to inform mitigation investments and recovery capabilities, and better protectNew Yorkers from future flood events.
