NYC Stormwater Flood Maps

The NYC Stormwater Flood Maps show areas in New York City that are at risk of flooding during heavy rain. The tool provides interactive maps that let users explore neighborhood-level flood risk and understand how stormwater might affect streets, homes, and critical infrastructure. It helps residents, planners, and local organizations identify vulnerable areas and make decisions about preparedness, emergency planning, and long term resilience.

These maps also bring together important environmental and social data, making it easier to compare neighborhoods, see patterns, and understand which communities may face the greatest challenges during extreme weather. Whether someone is writing a report, planning a project, or learning about local flood risks, this tool offers clear, accessible information to support informed decision-making in New York City.
