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.

To better understand how Connecticut’s coastal area marshes and roads may respond to sea level rise (SLR), Sea Level Affecting Marshes Model (SLAMM) was applied to Connecticut’s shoreline by Warren Pinnacle Consulting, Inc. This viewer displays the model’s results for Connecticut’s 21 largest marshes and all coastal area roads. For marshes, SLAMM was run two hundred times using alternative model inputs for key model parameters, including various SLR scenarios, to produce probability based results of likely future marsh conditions. For roads, the model uses a single SLR scenario of about 4.2 feet by 2100 from the base year of 2002. The Sea Level Rise Effects on Roads and Marshes projects is a project between CT DEEP and UConn CLEAR.

The LINAP Embayment Water Exchange Study looked at how water exchange practices could affect the nitrogen impairments in embayments. A water exchange practice changes the amount, speed, or direction of water moving through an area. The results of the study show that water exchange techniques are not effective in large waterbodies like most of Long Island’s embayments. Often, the physical size of the water exchange practice is small compared to the large waterbodies to which they are applied, which means their impact is limited. Water exchange projects may be useful, however, for smaller Long Island waterbodies, where the volume of increased water exchange approaches the volume of the overall waterbody. The goal of the study was to provide communities with basic information on water exchange practices suitable for Long Island.

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.

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.

The Maidstone Landing Association, situated between Town of Riverhead Iron Pier Beach and Hallock State Park, wanted to take action to mitigate erosion of their bluff. First they worked with Town of Riverhead to put up signage and fencing to stop beachgoers from climbing and driving on or near the bluff, which was causing significant destruction. Next they opted for a small-scale, nature-based approach to help stabilize the bluff. They purchased snow fencing from Home Depot and native beachgrass from Long Island Natives. They engaged Riverhead Charter High School to help with putting up the snow fencing and the plantings. The Maidstone Landing Association is using their bluff as an “outdoor classroom” to teach students and the public about the importance of conserving our coastal habitats and best practices.

In 2023, Long Island Sound Partnership 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.

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. This process brought together a diversity of stakeholders to develop a cohesive strategy for seven focal areas across Oyster Bay and 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. The partners will now work to implement the recommendations in the plan.

St. John’s Episcopal Church (lower Cold Spring Harbor) and Village of Lattingtown (Frost Creek) were 2024 LIS Resilience Planning Support Program awardees. Their projects will build off the Oyster Bay & Cold Spring Harbor marsh conservation plan and develop specific recommendations to enhance and restore marsh habitat in lower Cold Spring Harbor and Frost Creek.

In partnership with Sands Point Preserve Conservancy, an innovative cliff face stabilization system, engineered by Long Island based company Coastal Technologies Corp (CTC), was deployed as a pilot on Oct. 30th, 2022 at a steep & loose coastal moraine bluff located at The Sands Point Preserve, NY. The pilot project was designed to test the efficacy of this system to secure and stabilize sediment under constant erosive pressure preventing vegetation from taking hold. This bluff was selected due to its very high rate of stormwater & aeolian erosion. American beach grass, bayberry, beach plum & rose plugs, all protected from erosive forces, have thrived. Slope erosion was prevented by the devices, and all plants were successfully held against the slope, exactly as designed.

Friends of the Bay installed two raingardens at the Western Waterfront, which was done in October 2021 with the help of volunteers.

This project restored 46 acres of the Great Meadows Marsh in Connecticut that was degraded from dredge material that was dumped on site, poor drainage, and sea level rise. The marsh was also overrun with invasive plants and mosquitoes. A controlled fire was started to kill the invasive reeds growing in the marsh. Then a construction crew removed invasive plants and the dumped dredge material. Lastly, channels were carefully dug for tidal flushing which will allow the marsh to keep pace with sea level rise. Soil hummocks were constructed for Salt Marsh Sparrow habitat. Now the area continues to be monitored, assessed for resiliency, and provides a field for innovative solutions to be tested in.

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.

Dana Dam (aka Strong Pond Dam) at Merwin Meadows Park in Wilton, CT was the first barrier to upstream fish migration from Long Island Sound on the Norwalk River. A series of dams along the Norwalk River (historically, and presently) prevented fish from reaching their historic spawning grounds, have posed safety risks, and disconnected the river from its natural floodplain. On September 11, 2023, demolition of this dam began! In addition to restoring habitat and allowing fish passage, the removal restored natural floodplain connectivity, realigned 200 feet of river channel away from an active railroad embankment, and removed a known safety hazard.

This public greenspace was suffering from mosquito overpopulation, invasion from Phragmites, and poor tidal/stormwater drainage. The Wetland’s Habitat and Mosquito Management Program (WHAMM) created a new drainage area and tunnels, while also eliminating invasive plants. Then organizations and volunteers banded together to remove and replace invasive plant species with native plants.

This Avalonia and Sea Grant effort in Stonington, CT restored the preserve using native, well-researched plant species that would thrive in the forest and offer biodiversity. First, the area was cut down precisely to allow for new, ground-level growth. Then the preserve was seeded with plants chosen by the field team.

The purpose of this project was to mitigate 450 ft of coastal erosion on the Long Island Sound. A part of Crab Creek was moved further inland, thus allowing for beach and dune migration over time. New rock sills, plants, and sand sills were also positioned along the shore.

The NYSDEC document is to provide guidance on the issuance of permits for living shorelines techniques in the Marine and Coastal District Waters of New York (the Marine District) and encourages the use of green or natural infrastructure.

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 document developed in support of the NYS Community Risk and Resiliency Act 1) Describes natural resilience measures and how they can be used to mitigate the risks of flooding and erosion, 2) Provides definitions for different types of natural resilience measures and distinguishes among conserved, restored, nature-based and hard structural approaches, 3) Provides information on the value and benefits of using natural resilience measures, along with information on the co-benefits they provide, 4) Lists key factors to consider in the restoration, design and construction of natural resilience measures, and 5) Provides background to support the development of NYS agency guidance on natural resilience measures in the future

This fact sheet is intended to assist landowners in understanding the various shoreline management options and considerations for their shoreline.

The purpose of this fact sheet is to assist landowners in identifying and understanding the primary causes and processes responsible for erosion.

This guidance document is intended for stakeholders pursuing FEMA HMA grants for nature-based solutions to mitigate risks associated with flooding (riverine and coastal) and wildfire.

ReduceFloodRisk.org was developed by the Association of State Floodplain Managers to help property owners and buyers in flood prone areas identify strategies to reduce their properties risk of flooding.

Sustainable CT provides a wide-ranging menu of resilience best practices, opportunities for grant funding, and a voluntary certification program that recognizes thriving and resilient CT communities. Municipalities choose Sustainable CT actions, implement them, and earn points toward certification.

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.

This story map by the by the UConn Center for Land Use Education and Research (CLEAR) and the Naugatuck Valley Council of Governments (NVCOG) shows a snapshot of Connecticut Municipalities’ Low Impact Development Policies (LID) that are included plans of conservation and development, zoning/subdivision regulations, and stormwater/LID design manuals.

NOAA overview of living shorelines and their benefits, steps to construction. There is a good map of places where they have been constructed around the US. It is a good place to get basic info about living shorelines, with appropriate links to more specific information like how to get a permit

CT state resource on living shorelines, with a few good fact sheets and pages about types of living shoreline techniques and permitting for our state. There is also a list of pilot projects in CT.

This website provides an overview of each chapter of Connecticut’s new Stormwater Quality Manual, which includes guidance on how to design, install, and maintain these types of practices.

An effort by Save the Sound and Earth Economics to identify opportunities for the Federal Emergency Management Agency (FEMA) and other federal agencies and funders to improve the ability of benefit-cost analysis tools to account for ecosystem-based benefits.

The primary goal of this guide is to help communities identify and engage the staff and resources that can be used to implement nature-based solutions to build resilience to natural hazards, which may be exacerbated by climate change.

This guide gives community leaders five main strategies to carry out Nature-Based Solution projects: 1) Building Strong Partnerships, 2) Engaging the Whole Community, 3) Matching Project Size with Desired Goals and Benefits, 4) Maximizing Benefits, and 5) Designing for the Future. This is not a technical guide for planning, constructing, or funding NBS. It covers the value of each strategy and suggests how to move forward with NBS projects.

The Long Island Garden Rewards Program offers reimbursement of up to $500 total for making your yard more water friendly. Homeowners can be reimbursed for installing rain barrels, rain gardens, or native plantings on their properties. These actions reduce the amount of nitrogen pollution entering local waterways and helps conserve water. Funds are limited and available on a first come, first serve basis.

Due to the high participation in the program, as of May 20, 2025 the Long Island Garden Rewards Program is closed. Thank you to all who participated. Check back for when applications open again!

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.

Learn about living shorelines and their benefits to communities. This website contains training modules, a white papers database, a database of living shoreline projects, professionals directory, and online forum.
