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.

A Regional Needs Assessment to Help Build a Sustainable & Resilient Long Island Sound

This factsheet summarizes the findings of a 2022 informal needs assessment of coastal Long Island Sound communities conducted by the Long Island Sound Study’s Sustainable & Resilient Communities (SRC) Working Group Extension Professionals Team. The goal of the needs assessment was to guide future SRC work and to understand: 1) which environmental threats communities are most concerned about, 2) what communities are already doing to address these threats (including their goals and priority projects), 3) what barriers are preventing actions, and 4) what support is needed to overcome those barriers.
