Strengthening Maryland's Coasts

Helping Maryland’s critical coastal habitats and historic communities adapt to the effects of climate change.

Sea levels in the Chesapeake Bay have risen about a foot in the last century—an alarming rate at more than twice the global average. By 2050, models project that we could see an average of two feet of sea-level rise. With more than 7,000 miles of Atlantic and Chesapeake Bay shoreline, our communities across the state are already experiencing flooding, marsh loss and saltwater damage to agricultural fields.

Crisfield, Maryland
Building a Model For Resilient Communities

The Nature Conservancy and a variety of partners are working with the Town of Crisfield and members of its community to address challenges due to its low elevation and proximity to the Chesapeake Bay. In recent years, the town has become increasingly vulnerable to flooding, which is impacting the community and hampering economic growth. Tides have become more extreme, leading to more frequent nuisance flooding on roads that impede access to important parts of the community. Even smaller storms are having a more severe impact, often forcing schools and businesses to close and leaving property owners with expensive damage and losses. As in many small coastal communities, the severity of these impacts has been disproportionate to the resources available to address them.

For TNC and our partners, Crisfield represents a place that can serve as a model for improving community resilience to flooding. Starting in 2022, this led to a National Oceanic and Atmospheric Administration (NOAA) funded project to assess the benefits of potential new flood adaptation strategies to support the city’s planning efforts. 

The partners are also working with the town to build local capacity for supporting resilience-improvement projects that include an early flood warning system and an effort to map all of Crisfield’s drainage infrastructure. They are also exploring how nature-based solutions such as green infrastructure and marsh restoration can support the community’s long-term resilience.

SEAFARE: Improving access to climate adaptation funding for Maryland Communities

Maryland is experiencing one of the highest rates of sea-level rise in the country, but the most heavily impacted coastal communities in Maryland have not received climate adaptation and flood mitigation funding at the scale required to effectively improve resilience along its more than 7,700 miles of shoreline. Sea-level rise and other impacts of climate change disproportionately impact coastal communities—especially communities that have been historically underserved and overburdened—which are frequently also communities of color. These communities have the greatest hurdles to overcome to access climate adaptation funding, which includes complicated legislative frameworks, complex and alienating solicitation language and restrictive funding criteria. This results in climate adaptation programs that perpetuate and even exacerbate inequities.

The Supporting Equitable Access to Funding for Adaptation Resources—or SEAFARE—is the result of a series of workshops conducted by the Maryland/DC Chapter with climate adaptation practitioners, environmental justice leaders, non-profit partners, residents of coastal Maryland and state and federal officials to identify those barriers and create a toolkit with recommendations for decision-makers on ways to improve these funding systems. Check out our storymap and report to learn more.

Studying the Ecological Effects of Sea-Level Rise

Along Maryland’s Chesapeake and Atlantic coasts, tidal wetlands act as the first line of defense against storms and rising seas. To better quantify how these natural coastal features reduce the impacts of storm surge, TNC partnered with George Mason University (GMU) and the Maryland DNR on a wave attenuation study in 2018. After collecting data for one year from sensors installed on a Deal Island marsh, researchers found a striking data point: the first few feet of tidal marsh reduced wave height by up to 90%.

The success of the Deal Island wave attenuation study led to a three-year grant from NOAA’s Ecological Effects of Sea Level Rise (EESLR) Program to study and quantify the benefits of coastal habitats across Maryland's Chesapeake and Atlantic coasts. Now complete, the data from this study are being fed into models that are driving coastal conservation efforts led by state and federal agencies, and other NGO partners, around the Chesapeake Bay. TNC understands that demonstrating ways that nature provides value to people and communities is the best way to get real conservation results on the ground.

Grant Funded Restoration

Coastal habitat restoration has traditionally addressed single sources of degradation, such as sea-level rise, erosion, invasive species, etc. However, sites are usually impacted by a myriad of human-caused stressors. To better catalogue all potential sources of marsh degradation, TNC is partnering with experts to develop an innovative marsh management decision framework model, thanks to a one-year grant from the National Fish and Wildlife Foundation (NFWF). With current and projected rates of habitat loss, the Chesapeake Bay can no longer afford to continue business as usual. TNC and our partners will create an innovative decision framework that will help inform holistic tidal marsh management and restoration.

REPI Challenge

In late 2020, The Atlantic Test Ranges and Naval Air Station Patuxent River were awarded a $3 million grant from the Department of Defense’s Readiness and Environmental Protection Integration (REPI) Program to protect land on Maryland’s Eastern Shore. The funds will be used to purchase easements on 4,000 acres of land, establishing a resilient and connected marsh migration corridor and preventing incompatible development within the Navy’s fly zone. The U.S. Navy will partner with TNC, the U.S. Fish and Wildlife Service and others on the protection effort.

Since the award was announced, TNC has completed a land prioritization mapping exercise to identify the parcels that will provide the highest return on investment for people and nature. With TNC staff working on the ground with landowners, the Maryland REPI partnership is ready to begin the ambitious work of protecting 4,000 acres of critical coastal habitat.

Resilient Protection Frameworks

With sea-level rise transforming landscapes, TNC is aiming to address the intersection of marsh migration and landowner resilience. Building on the foundation established by the Maryland Department of Natural Resources (DNR), TNC has designed a project to lead marsh protection, coastal management and environmental finance experts in the development of resilient protection frameworks.

The frameworks will update protection easements and management plans to account for the impacts of sea-level rise. The goal of these frameworks are to ensure the healthy landward migration of Maryland’s tidal marshes while simultaneously preserving the cultural and financial interests of communities and landowners. 

A $2 million partnership with Lockheed Martin is funding the development of the resilient protection frameworks. This generous grant is also helping to fund our efforts to strengthen natural ecosystems, engage communities in adaptation planning and protect 4,000 acres of critical wetlands by 2025.
