This study by Seth et al. provides up-to-date information on observed trends and projections of temperature and precipitation in Connecticut.

The City of New Haven has installed 286 right-of-way bioswales throughout the city as part of a multifaceted approach to reducing flooding in the downtown area. Right-of-way bioswales are engineered planted areas that are located on sidewalks. They are designed to capture and infiltrate stormwater into the ground that would otherwise directly enter a storm drain. These bioswales were installed as the result of various partnerships and funding opportunities related to flood prevention, localized drainage solutions, combined sewer overflow mitigation, research, and traffic calming projects.

This project consists of 750 feet of shoreline in Stratford, CT. The goal of the project was to protect the beach from coastal erosion and to help combat sea level rise. The steps consisted of adding a smooth cordgrass marsh, artificial shellfish reefs (reef balls), high marsh, and a coastal dune area. The site was awarded the “Best Restored Shore Area” from the American Shore and Beach Preservation Association. To adaptively manage the site, a second restoration project is being developed to extend the marsh seaward by 0.35 acres over an additional 250 feet of shore using a combination of bagged slipper shell and small, modular oyster castles near the marsh edge, along with additional cordgrass plantings in the intertidal zone.

In 2023, Long Island Sound Study, New York Sea Grant and Warren Pinnacle, in partnership with committed municipalities and marsh-conservation groups/organizations, developed a Plan to understand the benefits, threats and recommended conservation actions at seven focal areas across the harbors. The goal of the Plan is to inform local municipalities and marsh-conservation groups as to where they might focus their conservation efforts to maximize the conservation of marsh ecosystem services under sea-level rise conditions. Seven focal areas across Oyster Bay & Cold Spring Harbor: Frost Creek, Mill Neck Creek, West Shore Road, Bayville Bridge to Centre Island, Centre Island, Shore Road, and Lower Cold Spring Harbor.

In 2023, Long Island Sound Study and Warren Pinnacle, in partnership with committed municipalities and conservation groups/organizations, developed a Plan to understand the benefits, threats, and recommended conservation actions for the Stony Brook Harbor and West Meadow Creek marsh ecosystem. The goal of the Plan is to help inform conservation and restoration efforts to maximize marsh ecosystem services under rising sea levels.

This comprehensive study and plan, funded through the National Fish and Wildlife Foundation, Long Island Sound Futures Fund, identifies initial strategies to maintain and enhance the local watershed resources of Crab Meadow. It is meant to be a land management tool to guide the implementation of best practices. The plan was developed in consultation with many partners and stakeholders.

In 2023, Long Island Sound Study and Warren Pinnacle, in partnership with Westchester County and conservation groups/organizations, have developed a Plan to understand the benefits of, threats to, and recommended conservation actions for marsh ecosystems on Glen Island Park in New Rochelle, NY. The goal of the Plan is to help inform conservation and restoration efforts to maximize marsh ecosystem services under rising sea levels.

The Long Island Tidal Wetlands Trends Analysis measures wetlands loss and changes in marsh condition within the Long Island Sound, Peconic, and South Shore estuaries including all or parts of Westchester, Bronx, Queens, Nassau, and Suffolk Counties between 1974 and 2005/2008. The results of this project are intended for use by environmental managers, conservation advocates and elected officials across a variety of regulatory agencies, environmental organizations, and governments.

This mapper is intended to provide federal, state, and local managers with tools to estimate the vulnerability and ecosystem service potential of wetlands. It allows you to display information on the unvegetated to vegetated ratio (UVVR), marsh elevation, tidal range, and shoreline change rates for New York’s tidal wetlands.

Coastal Resilience is a Connecticut-based decision support tool that provides local, regional, state and national stakeholders a step-wise process to guide decisions to reduce the ecological and socio-economic risks of coastal and inland hazards.

Save the Sound’s Sound Health Explorer displays information on water quality for Long Island Sound beaches, embayments, and open waters.

Developed by The Nature Conservancy, this tool identifies priority road-stream and tidal crossings in Suffolk County for replacement or upgrades. Prioritization is based on social and ecological criteria. Additionally, it includes data on current and future projected flooding and marsh extent under various sea level rise scenarios. The tool is meant to be a screening tool for planning efforts.

This floodplain mapper shows the estimated boundary of future coastal floodplains for different sea level rise scenarios for New York State. Customize a scenario by choosing the amount of sea level rise in inches and a coastal flood recurrence interval.

New York State sea level rise projections. The New York State Department of Environmental Conservation is currently updating these projections.

The 2022 State Climate Summaries provide new information on assessment topics directly related to NOAA’s mission, specifically historical climate variations and trends, future climate model projections of climate conditions during the 21st century, and past and future conditions of sea level and coastal flooding. Select your state to find state-level information for observed changes in climate, including both long-term trends and extreme weather events.

Use this web mapping tool to visualize community-level impacts from coastal flooding or sea level rise (up to 10 feet above average high tides). Photo simulations of how future flooding might impact local landmarks are also provided, as well as data related to water depth, connectivity, flood frequency, socio-economic vulnerability, wetland loss and migration, and mapping confidence.

Use this mapper to visualize people, infrastructure, and natural resources exposed to coastal flood hazards. You can save and share the online maps to communicate with stakeholders. Tip: watch the short video about the tool before getting started!

MyCoast NY collects and catalogs photos provided by volunteers that document changing water levels, shorelines, and hazardous weather impacts across New York’s varied coasts and water bodies. Photos are linked to real-time environmental conditions to create flooding and storm impact reports that help stakeholders like government agencies, business owners, and residents understand our changing environment and make informed decisions.

Submit your coastal flooding photos through this website/app. Photos are linked to real-time environmental conditions to create flooding reports that help stakeholders understand our changing environment and make informed decisions.

The purpose of the interactive viewer is to illustrate the fate of significant marsh systems on Long Island Sound under future Sea-Level Rise conditions. Model results are combined with tax-parcel information and integrated with information about marsh ecosystem services to assist municipalities and conservation groups in defining and assessing various land-management alternatives.

Provides the most up-to-date sea level rise projections for all U.S. states and territories, out to the year 2150. Extrapolations of available tide gauge observations are also provided.
