The Community Flood Watch project is a growing network of residents and community groups that report and share resources related to flooding in their communities. Residents submit photographs and reports that document flood event timing, depth, location, and associated impacts. Researchers can use these reports to improve flooding forecasts and alerts.
The NYU FloodSense team is working to generate real-time data on the frequency, depth, and duration of hyperlocal flood events to improve urban resiliency. The team of interdisciplinary researchers at NYU has developed and deployed ultrasonic-based flood sensors that overcome common remote sensing challenges such as durability, connectivity, and power for longitudinal urban operation. Additional research includes the presence and impact of floodwater contaminants.

High Tide Flooding leads to public inconveniences such as road closures, overwhelmed storm drains, and compromised infrastructure, is increasingly common (on average ~50% since 20 years ago, 100% since 30 years ago) as coastal sea levels rise.
As relative sea level increases, it no longer takes a hurricane or strong storm to cause flooding. Communities experience flooding now with high tides due to climate-related sea-level rise, land subsidence, and the loss of natural barriers.
NYC Department of Environment Protection (DEP)
Stormwater is the rain and melting snow that falls on our rooftops, streets, and sidewalks. As stormwater flows, it sweeps up pollutants such as soils, chemicals, sediments, pathogens, and trash. Rather than being absorbed naturally into the ground, much of NYC’s stormwater eventually flows into storm drains or catch basins, and from there into the sewer system.
NYC DEP oversees a broad citywide effort to better manage stormwater to improve the health of our local waterways and prevent flooding through Green Infrastructure, Bluebelt, and Long Term Control Plan programs.
