The Long Island Sound Sustainable and Resilient Communities (SRC) Team held our 2025 Annual Workshop virtually as three sessions over two days. Session topics focused on resources and tools available to help take advantage of state resilience funds, a panel discussion on why and how to incorporate nature-based solutions into resilience planning, and an overview of our available assistance programs.

Session 2 – Using Nature-Based Solutions for Resilience: A Panel Discussion on Common Challenges & Strategies for Success was held on Thursday, December 4, 2025. In this interactive session, practitioners and experts discussed techniques for integrating nature-based solutions into resilience initiatives. The panel highlighted common challenges and shared successful strategies from projects in the Long Island Sound region. Video of the session along with supporting materials is available below.

The Atlas of Inspiration is a national database that highlights real projects helping communities adapt to extreme weather, flooding, heat, and sea-level rise. It showcases innovative infrastructure, planning strategies, and funding approaches that can be adapted or scaled by other communities. The Atlas is designed to celebrate successful ideas and give decision-makers examples they can use when seeking state or federal funding.

The Atlas is fully searchable, allowing users to browse projects by type, climate hazard, or location. It builds on Rebuild by Design’s earlier work including the Atlas of Disaster and the Atlas of Accountability by showing not only the risks communities face, but the solutions that are already making a difference.

Rebuild by Design also invites communities to share their own climate resilience projects for inclusion in the Atlas. Submissions help expand the collection and highlight new approaches being used across the country.

Connecticut’s Severe Weather Mitigation and Resiliency Advisory Council was created to help the state better prepare for the growing risks of hurricanes, flooding, and other severe weather events. According to the Council and the CT Insurance Department, many Connecticut homes especially older buildings or houses in coastal and urban areas are highly vulnerable to wind and flood damage. The Council’s final report explains that severe weather is becoming more expensive for families, and many residents lack the insurance or financial resources to recover after storms. To address this, the Council recommends strengthening partnerships with programs like Energize CT, Habitat for Humanity, and the CT Green Bank, and promoting upgrades such as IBHS Fortified™ roofs, which can reduce damage from high winds. They also emphasize the need for public education about flood risk, insurance awareness, and preparedness, along with long-term actions like statewide grant programs, tax credits, and expanded training for contractors and evaluators. Together, these efforts aim to help Connecticut residents protect their homes, reduce storm damage, and build a safer, more resilient future.

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 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. There is now significant community buy-in to take action to protect and restore this important watershed. 

Following adoption of the plan, the Town of Huntington began working with US Fish and Wildlife Service and Audubon to study and restore Crab Meadow marsh and implement recommendations from the Stewardship Plan. Audubon, in partnership with Town of Huntington and USFWS, received a 2024 Long Island Sound Futures Fund Grant ($429K) to develop design plans for marsh restoration at Crab Meadow.

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.
