Level of Effort:
The USGS Long Island Sound Partnership Compound Flood Hazard Web Map Application is an interactive tool developed by the U.S. Geological Survey’s New York Water Science Center that helps users explore the combined impacts of multiple flooding drivers across the New York and Connecticut coastal regions. Drivers of compound flooding included in the assessment were precipitation, coastal (storm surge, tidal), and groundwater emergence, which when combined can lead to more severe and widespread inundation than from any single cause alone.
The map visually displays hazard rankings and spatial patterns of flood drivers so that planners, emergency managers, researchers, and the public can better understand where these flood hazards are most likely to coincide, thus supporting local decision making for flood mitigation, coastal planning, and resilience strategies. The application is based on USGS models and ongoing research into regional flood processes.

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.

Report
Level of Effort:
Connecticut’s Severe Weather Mitigation and Resiliency Advisory Council was created to help the state better prepare for the growing risks of hurricanes, flooding, and other severe weather events. According to the Council and the CT Insurance Department, many Connecticut homes especially older buildings or houses in coastal and urban areas are highly vulnerable to wind and flood damage. The Council’s final report explains that severe weather is becoming more expensive for families, and many residents lack the insurance or financial resources to recover after storms. To address this, the Council recommends strengthening partnerships with programs like Energize CT, Habitat for Humanity, and the CT Green Bank, and promoting upgrades such as IBHS Fortified™ roofs, which can reduce damage from high winds. They also emphasize the need for public education about flood risk, insurance awareness, and preparedness, along with long-term actions like statewide grant programs, tax credits, and expanded training for contractors and evaluators. Together, these efforts aim to help Connecticut residents protect their homes, reduce storm damage, and build a safer, more resilient future.
