"Community Disaster Resilience Zones aim to build and strengthen community resilience across the nation by driving federal, public, and private resources to the most at-risk and in-need communities. The Community Disaster Resilience Zones Act uses FEMA’s National Risk Index to identify the most at-risk and in-need communities to identify resilience zones. Designated zones will be prioritized for targeted federal support, such as increased cost-share for resilience and mitigation projects, lessening the financial burden on communities to perform resilience-related activities. In September 2023, FEMA announced the first 483 CDRZ in all 50 states and the District of Columbia. In November 2024, 275 census tracts were designated for Tribal Nations and U.S. territories and in January 2025, an additional 55 census tracts were designated for Tribal Nations."

A new law signed by President Biden on Dec. 20, 2022— the Community Disaster Resilience Zones Act—will build disaster resilience across the nation by creating and designating resilience zones which identifies disadvantaged communities most at-risk to natural hazards.This new law amends the Robert T. Stafford Disaster Recovery and Emergency Act and applies FEMA’s National Risk Index to identify communities that are most vulnerable to natural hazards.These designated zones will receive targeted support to access federal funding to plan for resilience projects that will help them reduce impacts caused by natural hazards. It will also enable communities to work across a range of federal and private sector partners to target funding and provide technical assistance, strengthening community resilience.Designated zones will receive targeted federal support, such as increased federal cost-share for the Building Resilient Infrastructure and Communities program, lessening the financial burden on communities to perform resilience-related activities. This product explains where Community Disaster Resilience Zones are, how they were created, and what users can do with that information. Within the product, users are able to identify the FEMA Community Disaster Resilience Zones, which target Census tracts identified as disadvantage communities most at-risk to natural hazards as a part of the Community Disaster Resilience Zones Act. In addition, supporting and related data are overlaid, incorporated into widgets, and/or available as additional layers in the map. Users are also encouraged to add and overlay their own data. The data methodology is available on the "Designation Methodology" page of the product. Data Sources-FEMA Community Disaster Resilience Zones (FEMA), ESRI Living Atlas
