Hurricane season usually starts winding down in October, and we can only hope that the season closes quickly this year.

This storm season has shown just how vulnerable our coastal areas are, with 13 named storms including two category 5’s (Irma and Maria) and two category 4’s (Harvey and Jose). More than a hundred people have died in the United States and territories, and millions of people are still struggling through the aftermath of these destructive storms. Our hearts are with them, including our FWS staff who are out on the front lines in Puerto Rico, the U.S. Virgin Islands, Florida and Texas.

Many citizens are wondering what can be done. As communities begin the arduous task of rebuilding what was lost, it’s important to consider how “natural” infrastructure can make coastlines more resilient — the marshes, wetlands, beaches, free-flowing rivers and oyster reefs that help absorb storm energy and reduce flooding.

Natural infrastructure can’t stop the storms from coming; but it can help lessen the impacts – immediately, and long into the future. Natural infrastructure reduces the impacts of storms and sea-level rise and helps communities recover more quickly. And these natural areas have huge value for wildlife and people all year round – in the form of ecotourism, outdoor recreation, cleaner water, cleaner air, improved health and more.

The U.S. Fish and Wildlife Service – along with many partners at the federal, state and local levels – is working with nature to build a stronger coast. We’ve been restoring marshes and beaches, building living shorelines, removing dams and conducting innovative science to help guide conservation efforts into the future.

In October we’ll be highlighting some of this work on our blog and through social media – including a dam removal in urban New Haven, Connecticut, a river restoration in Rhode Island, a beach restoration in New Jersey and more. Much of this work was funded in the aftermath of Hurricane Sandy, which closed out the 2012 storm season with a bang on October 29.

The destruction caused by Sandy provided a window of opportunity to help wildlife and people prepare for and adapt to a changing environment by creating a more resilient coast – one that uses natural infrastructure to help lessen the damage of storms and sea-level rise while providing important natural areas that wildlife and people need.

People Behind a Stronger Coast: Eric Schrading and Katie Conrad

“The Fish and Wildlife Service office was in Pleasantville when Hurricane Sandy hit, right near Atlantic City. We closed the day before and took preparations. Where I live, we had high winds, some damage on the house. We just kept our family close and hoped to carry through the storm,” says Eric Schrading, pictured above with USFWS biologist Katie Conrad at Gandy’s Beach, New Jersey. Photo: Steve Droter

Located on the Delaware Bay side of the New Jersey coast, Gandy’s Beach was hit pretty hard by Hurricane Sandy. “Most of the houses here were completely flooded. In some cases there was so much erosion that a house was undermined and had to come down, or had to be abandoned,” says Schrading. Photo: Steve Droter

In the wake of Sandy, federal funding helped fuel efforts to build a better natural defense system. “There’s a Nature Conservancy preserve here, and we knew they were interested in taking action. They had a ‘shovel-ready project,’” says Schrading, pictured at right with Conrad (left) and Moses Katkowski (center), Coastal Projects Manager at The Nature Conservancy. “Partnerships are really crucial, and the important thing was having a plan in place.” Photo: Steve Droter

The partners, together with the help of volunteers, built over 3,000 feet of living shoreline oyster reefs. “Waves hit the living shoreline and the wave energy gets dissipated over the structure. That’s different from bulkheads or sea walls, where the energy is not dissipated – what they do instead is basically take all that energy and force it down, which causes continual erosion,” explains Schrading.

The reefs are made of concrete blocks, similar to interlocking LEGOs, and filled with bags of oyster or clam shells. Says Conrad, “The oyster shells come from Dock’s Oyster Bar in Atlantic City – The Nature Conservancy goes there every week or so and picks up oysters from the restaurant and brings them to a site to cure for a few months before they’re bagged. The clam shell is sourced from LaMonica Fine Foods in Millville, NJ. And the spat (baby oysters) are natural, they are already in the water here at Gandy’s.” Photo: Steve Droter

“The long-term goal is that these castles get covered with oysters and barnacles and a lot of other marine life,” says Schrading. “So once we’ve created this foundation, more and more marine life will continue to grow on it and it will be a self-sustaining reef system. That’s the key – you can build this and then walk away and have it be self-sustaining, versus constantly going in every 5 or 10 years to rebuild the structure.” Photo: Steve Droter

“Coir logs (pictured) help by stabilizing the marsh edge,” says Conrad. “Coir is a material made out of coconut and it’s good for working in salt marshes because it’s water resistant and doesn’t degrade quickly in salt water. We place the coir logs in the marsh to accumulate sediment behind and then we can plant marsh plants in the sediment and expand the marsh.” Photo: Steve Droter

“The commercial areas here are driven by bay men – people who work on the bay and make their living on the bay, oyster dredging, going out getting crabs or clams,” says Schrading. “Gandy’s Beach itself is a recreational community, some long-term residents, some who use it as a summer place. It’s a pretty close-knit community.” Photo: Steve Droter

Delaware Bay coastal areas like Gandy’s Beach are important for birds – from red knots and black rails to harriers, raptors and waterfowl. “We want to build up the beach areas to make them better for horseshoe crab spawning and shorebird foraging for red knots – anyplace where horseshoe crabs spawn and produce eggs and can feed red knots on their trip north is important,” says Schrading.

“Sandy was the biggest storm I’ve been in,” says Conrad. “It made me realize how important these [natural] structures are in helping to enhance habitat but also protect communities. Traditional hard structures that are used for reducing shoreline erosion don’t provide habitat and they don’t absorb wave energy so they can cause further erosion. I think these [natural] structures should be used more.” Photo: Steve Droter

“It’s scary, especially when you think about climate change. It’s not fun living through a hurricane. A lot of people got really hurt, but it may be worse in the future,” says Schrading. “One thing I’ve learned about climate change is, you have a lot more energy with warming climates, a lot more energy in the system. And with more energy that means more intensity and higher frequency of storms, so that’s something to think about.” Photo: Steve Droter

It’s a windy day at Gandy’s Beach, on the Delaware Bay side of the New Jersey coast, and everyone is having a hard time keeping their hats on. The waves are choppy, kicking up plenty of surf – the perfect weather for witnessing the benefits of the living shoreline oyster reef recently built here.

“When a wave hits, there are a lot of nooks and crannies in the reef that dissipate the wave throughout the whole structure or deflect it to the sides or down,” explains Eric Schrading, supervisory biologist at the U.S. Fish and Wildlife Service’s field office in New Jersey. “But none of that energy is forced into one particular direction, and that’s what the key is behind these – there’s a variety of directions that the wave energy can be dissipated.”

Schrading is standing on the shore with fellow FWS biologist Katie Conrad and Nature Conservancy partner Moses Katkowski. They are some of the key players behind the living shoreline project at Gandy’s Beach to repair and build coastal resiliency in the wake of Hurricane Sandy. The project is funded with $880,000 from the Hurricane Sandy Disaster Relief Appropriations Act of 2013.

The living shoreline oyster reef, located just offshore, creates a natural defense system against the ongoing erosion and flooding that plague this coastline and community. Historical records indicate the Gandy’s Beach shoreline has eroded by 500 feet since the 1930s – and, with climate change bringing more frequent and intense storms and rising seas, the rate of erosion is likely to pick up.

“All the wave energy goes up on the beach or, where there’s little beach, it hits the marsh mostly at the roots,” explains Schrading. “So it just keeps hitting over and over again, and creates this scalloping effect where it takes away the soil underneath the vegetation, the vegetation then slumps in and you have continued erosion.”

Since 2014, the partners – along with help from dozens of volunteers – have built more than 3,000 feet of living shoreline oyster reefs along the coast at Gandy’s. Once in place, the structures recruit new oysters and eventually build up to be a self-sustaining reef system.

“We’ve been surprised at how many oysters have been recruited since we started this project,” says Conrad. “We put out pilot reefs in the summer of 2014 and they accumulated a lot of oysters.”

Hurricane Sandy dealt a massive blow to Gandy’s Beach and surrounding areas, so making this coastline more resilient to future storms is crucial. The living shoreline protects about one mile of sandy beach and adjacent salt marsh and is projected to reduce incoming wave energy by up to 40 percent.

“Maybe with major hurricanes these structures themselves won’t do much, because everything’s going to be under water, the structures will be 12 feet underwater,” acknowledges Schrading.

“But on days like today you see their value because you have a strong fetch that comes across the bay, and the first thing that it hits is the sandy beach or the marsh areas. But if you have these living structures in place, it basically takes that energy out of the wave before it hits the beach – it reduces a lot of wave force, which causes erosion in the first place.”

Four Years After Hurricane Sandy

This week marks the 4th anniversary of Hurricane Sandy, an event that lives on in the minds and hearts of many of us who call the East Coast home.

In the wake of Sandy’s destruction, the U.S. Fish and Wildlife Service received $167 million in federal funding to strengthen natural defenses and protect communities and wildlife along the Atlantic Coast from future storms.

Four years later, here’s a by-the-numbers look at what we’ve done to build a stronger coast as of October 2016:

• 3,500 tons of hurricane debris removed from refuges;
• 5 badly eroded beaches restored on Delaware Bay;
• 7 refuges installed with solar and back-up power;
• 20 refuges repaired for visitor and staff safety;
• 6 dams removed to improve river flow and reduce flood risk;
• 4,000 acres of invasive species treated;
• 30,000 feet of living shoreline developed;
• 1000s of native plants planted to restore wetlands, rivers and marshes;
• 4 breaches fixed, 9,000 feet of shoreline restored, 500,000 plugs of beach grass planted, 1,000 acres of marsh seeded, and 25 miles of channels dredged at Prime Hook National Wildlife Refuge – one of the largest coastal restoration projects on the East Coast.

Some highlights of our 2016 work:

Removal of the 150-foot-long Hughesville Dam on the Musconetcong River in New Jersey to restore fish passage and reduce flooding risks for the local community – a project that caught the eye of Secretary of the Interior Sally Jewell, who toured the site in September.

Science tells us that the future will include more intense hurricanes and storms like Sandy, causing more damage to coastal ecosystems and communities. In fact, a recent study predicts disastrous floods like those seen during Hurricane Sandy may hit New York City 17 times more often in the next century.

With anticipated rising sea levels, more frequent and intense storms, shifting seasons and higher temperatures, we need to continue to work together to better understand and adapt to changing conditions. Strong natural defenses will help all of us better weather future storms.
