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.

Building a Resilient Trail

This report provides on guidance on ways to adapt the Shoreline Greenway Trail to the increasing frequencies of heavy rain, wildfires, hurricanes, flood events, and storm surges. The report defines what we mean by resilience for a trail in coastal Connecticut, identifies climate impacts facing the trail now, and in the years to come, shares design suggestions that could build resiliency on existing and new sections, and explores how the trail itself can be essential to wider community resiliency.
