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 U.S. DOT’s BUILD grant program provides grants for surface transportation infrastructure projects with significant local or regional impact. The eligibility requirements of BUILD allow project sponsors, including state and local governments, counties, Tribal governments, transit agencies, and port authorities, to pursue multi-modal and multi-jurisdictional projects that are more difficult to fund through other grant programs. Projects can be for planning or construction and are evaluated by their ability to address: safety; environmental sustainability; quality of life; mobility and community connectivity; economic competitiveness and opportunity including tourism; state of good repair; partnership and collaboration; and innovation.

The BUILD program was previously known as the Rebuilding American Infrastructure with Sustainability and Equity (RAISE) and Transportation Investment Generating Economic Recovery (TIGER) discretionary grants.  

The Connecticut Department of Energy and Environmental Protection (DEEP) is accepting applications for the next round of the DEEP Climate Resilience Fund (DCRF).

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.

The Connecticut Department of Energy and Environmental Protection’s (DEEP’s) Land and Water Resources Division requests proposals for the new CT DEEP Long Island Sound Ecosystems Grant, made possible by financial support provided by the Long Island Sound Partnership from the U.S. EPA.

The Hempstead Harbor Protection Committee and Village of Sea Cliff completed subwatershed improvements at Scudders Pond to address stormwater drainage problems impacting the water quality of the pond and Hempstead Harbor, highlighted as a priority in the 1998 Hempstead Harbor Water Quality Improvement Plan. The improvements included dredging the pond, installing a hydrodynamic separator to intercept sediment, removing invasive Phragmites australis and replacing with native plants, realigning the stream to reduce erosion, redirecting the stormwater from residences to the bioswale, creation of a biofilter wetland area, replacement of the weir between the upper and lower ponds and weir at Shore Road.

Increased development and the historic construction of a dam on Sunken Meadow Creek in the 1950’s led to reduced tidal exchange, increased water levels in the creek, poor water quality, and the proliferation of invasive species. In 2008 a number of partners (NYS OPRHP, NOAA, NYSDEC, LISS, TNC, Save the Sound, USFWS, LI Botanical Society) came together to work to restore the degraded marsh habitat around Sunken Meadow Creek, increase tidal flow, improve aquatic organism passage, limit invasives, and improve water quality. A restoration feasibility study was completed in 2010. In 2012 Superstorm Sandy blew out the dam on Sunken Meadow Creek, naturally kick-starting restoration. Following Superstorm Sandy, the project partners were able to quickly capitalize on available funding and grants, due to their prior planning efforts. A bridge was built across the Creek where the dam blew out, salt marsh habitat was restored at three locations, green infrastructure was installed in one of the parking areas to capture and treat stormwater runoff, fish passage feasibility on the creek was investigated, and education and outreach was conducted to thousands of people. These projects were completed in 2019. Now, with funding through Long Island Sound Futures Fund, Audubon NY is leading a large-scale marsh restoration project at Sunken Meadow Creek to restore important high-marsh habitat for at risk species, like the Saltmarsh Sparrow, and to increase the resilience of the marsh in the face of rising sea levels. Audubon will be working to finalize the designs and secure permits over the next two years, with on-the-ground restoration expected in 2026.

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.
