USGS Compound Flood Hazard Web Map

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.

Case Study

Project

Hamden, CT

Town of Hamden’s Bioretention Project

The Town of Hamden’s Bioretention Project is the largest municipally owned rain garden in the state! Save the Sound, in partnership with the Town of Hamden, completed this large-scale rain garden project at Hamden Town Center Park to improve local water quality, restore habitat, and enhance community resilience. The project transformed approximately 2.5 acres of lawn into a functioning green infrastructure system that now manages runoff from an 88-acre urban watershed draining Dixwell Avenue and surrounding neighborhoods. Prior to the project, stormwater often overflowed directly into Pardee Brook and the Mill River, carrying pollutants and inundating the park.

The newly constructed rain garden was engineered with layers of soil, sand, and rock, and planted with more than 7,000 native grasses, flowers, and shrubs thanks to additional support from the Land Trust of Hamden. These plantings naturally filter pollutants such as fertilizers, road salt, and chemicals. Community volunteers helped complete the planting, strengthening local stewardship in the Town of Hamden.
