The NYC Hazard Mitigation Plan (HMP) identifies natural hazard risks and vulnerabilities that are common to New York City. After identifying these risks, the HMP develops long-term strategies for reducing those risks and vulnerabilities. Mitigation plans are key to breaking the cycle of disaster damage and reconstruction.
The NYC Hazard Mitigation Plan (HMP) establishes New York City’s eligibility for Hazard Mitigation Assistance (HMA) funding, providing an incentive for funding in the future. Furthermore, it serves to guide and direct a greater vision for City agencies and partners to help New York City reduce the risk of natural hazards and make New York City more resilient to disasters. The HMP not a policy document nor is it an enforceable mechanism for specific actions.
New York City is no stranger to disasters. Throughout its history the city has been confronted with natural and non-natural hazard events. This includes hurricanes, flooding, disease outbreaks, earthquakes, and cyber-attacks among many others. Each time we experience one of these events, we learn how to make our city more resilient. These events underscore the need to identify and manage risk. We must learn from the past to shape the future.
Historically, the response-recovery and repeated damages cycle prevailed. This is changing. New York City has fundamentally shifted towards mitigation, the critical step that can break this cycle and reduce losses after a disaster. It is estimated that for every one dollar invested in hazard mitigation, an average of six dollars is saved in the long-term.
New York City Emergency Management (NYCEM) is excited to release this web-based Hazard Mitigation Plan. This plan will ensure we can continuously identify, assess, and reduce our risk from an array of hazards threatening our city. As a result, this Hazard Mitigation Plan is iterative and evolving. Centralizing this information can serve as a tool for our city, businesses, communities, and research. We look forward to receiving your ongoing feedback.
The 2024 NYC Hazard Mitigation Plan includes:
- Hazard Environment: Key features of the city’s environment that make it vulnerable to natural hazards.
- Hazard Profiles: Risk assessments for hazards discussing probability, location, and historic events.
- Mitigation: Strategies and specific City-led actions for managing risks associated with each of these hazards
- Tools: Purpose built tools for assisting you in understanding hazards in New York City.
- Community Resources: A list of external resources you can use to further understand and plan for hazards, including financial resources and preparedness material.
In March 2009, New York City Emergency Management (NYCEM) completed the first HMP to help make the city more resilient to hazards.
In April 2014, NYCEM, in partnership with the New York City Department of City Planning (DCP) and in close coordination with the then New York City Mayor’s Office of Resiliency (MOR), completed the first update to the 2009 HMP. The Plan was effective April 17, 2014 – April 17, 2019.
In May 2019, NYCEM released the nation’s first web-based Hazard Mitigation Plan. The web-based HMP builds upon New York City’s continued effort to create a resilient city. It represents a new chapter in the City’s efforts to increase public awareness about the risks faced from a range of hazards and to help the City’s partners invest in mitigation now and in the future.
NYCEM decided to move toward publishing a web-based HMP versus a document-based format to reflect the dynamic process New York City is using to update its hazard-mitigation actions and to keep its list of expanding city-wide resiliency initiatives current. NYCEM is continuously focused on hazard risk and mitigation. The landscape of information and initiatives is always changing, and a web-based approach ensures the HMP is always relevant.
