Imagine going to bed thinking your home is safe only to wake up and discover that you’re living in the middle of a vulnerable flood zone.
That’s essentially what happened to millions of Americans recently when the research and technology nonprofit First Street Foundation released a report showing how much damage climate-induced flooding could inflict on homes and businesses in the next 30 years. Read More
Hurricane season is just around the corner, but experts are already predicting an above-average season.
Researchers at Colorado State University and meteorologists at Accuweather each released predictions indicating that the 2020 Atlantic hurricane season could be cause for concern with the potential for up to nine hurricanes and an “above-average probability for major hurricanes making landfall along the continental United States.”
Adding additional concern, water temperatures in the Gulf of Mexico are currently extremely warm, creating a recipe for intensifying storms. Read More
As my fellow North Carolinians prepared for the arrival of Hurricane Dorian last week, many were still reeling from the devastation that Hurricane Florence inflicted upon communities and businesses last year. And that’s to say nothing of the misery that Hurricane Matthew wrought upon residents two years before that – or the smaller flooding events that are now challenging folks with more regularity.
As we work toward recovery, we need to think about how we adjust to this new normal and build resilience in the face of increasingly intense storms and sea level rise.
As Gov. Roy Cooper said when testifying before the U.S. House Natural Resources Committee in February, “When storms are becoming more destructive, it’s not enough to pick up the pieces. We must take action to prevent this kind of devastation in the future.” Read More

2019 has been an unprecedented year for extreme weather, and we’re still in the thick of hurricane season. As disasters have increased, so has the popularity of using nature-based solutions to reduce flood hazard and exposure while also benefiting ecosystems and wildlife.
Along our coasts, healthy natural features – such as mangrove forests, wetlands, reefs and barrier islands – can be used to absorb the shock of storm surge, waves and rising sea levels. Further inland, nature-based features along rivers and in their floodplains can slow and retain water to help protect nearby communities.
In terms of public awareness, funding and policy, natural infrastructure is gaining steam as a critical strategy to help people and property become more resilient in the face of extreme weather. Read More
Call 2019 the year of the flood.
This spring large swaths of the nation experienced moderate to severe flooding – and the rain isn’t stopping. In California, record rainfall and snow persisted into May. In Louisiana, for the first time ever, the Army Corps of Engineers just released water through its Bonne-Carré spillway twice in a single year to avoid flooding. And hurricane season is just beginning.

The deluge of floods is hardly a coincidence.
Land-use changes and extreme weather driven by climate change are delivering a one-two punch that heightens flood risk. We’ve increased impervious surfaces – think asphalt and concrete – and at the same time we’ve removed wetlands, prairies and forests, which can absorb water and slow runoff. We’ve also built hard infrastructure such as bridges, urban and agriculture drainage networks, and even, ironically, flood “protection” projects that often alter watersheds, floodplains and stream hydrology and increase the severity of floods.
So how do we better protect critical infrastructure and communities in the face of increased flooding? Read More
My upbringing drew me to work in coastal hazards. Though I work on coastal resilience in Louisiana, I spent much time throughout my childhood and adult life in Odisha, a state with a 300-mile coastline along the Bay of Bengal. Odisha is part of the bay’s infamous cyclonic zone that stretches across the Bangladeshi lowlands, and its coastline has been subjected to devastating storms and floods intensified by the effects of global warming and sea level rise.

This week, the Army Corps of Engineers formally released an important resource guide, “Engineering with Nature: An Atlas.” This isn’t your typical government issued atlas of maps and figures. It’s an important first step toward broadening understanding, consideration and acceptance of natural infrastructure as a flood risk reduction and resilience strategy.
The glossy compendium of 56 Corps projects illustrates that restoring nature and using nature-based features and processes – such as dunes, wetlands, reefs, functioning floodplains and rivers – can efficiently yield real economic, environmental and social benefits.
Here are four ways the atlas helps to advance natural infrastructure solutions. Read More
Florida and North Carolina are once again recovering from hurricanes – this time, from two of the largest storms to hit our coasts in a century. In a climate-driven world, an important aspect of recovery is rebuilding in ways that make communities safer and more resilient to storms.
One strategy for reducing future flood risks is restoring natural features such as barrier islands, dunes, wetlands and floodplains. These natural infrastructure solutions help slow storm surge and hold flood waters, reducing the devastating impacts of storms.
Even where a dune was completely lost during a storm, it did its job. A dune’s job is to be a chew toy for waves, so that roads and houses aren’t being chewed on. (Photo Credit)
Yet, despite what we know about the effectiveness of these features, natural infrastructure is still an underutilized resilience strategy.
While there is broad agreement that natural infrastructure can be an effective, sustainable means to reduce flood damages, existing information gaps make it difficult for city planners, engineers and decision-makers to fully support these practices. The good news is there is work already underway to help fill these gaps and make natural infrastructure solutions more accessible. Read More
I was recently cleaning out old files and came across notes from a presentation I made after the Great Midwest Flood of 1993. It was on the state of the nation’s floodplain management, a topic even more relevant today.
Many no longer recall the Great Midwest Flood despite its record-breaking precipitation, flooding and $13 billion price tag. Sure, 1993 seems like a long time ago, but I believe the reason the flood has left most people’s memory is because, over the last 25 years, the nation has experienced one devastating, record-breaking flood after another. Our memories are diluted by the frequency of such events.
Sadly, many of the lessons I shared in my presentation back then remain true today.
It’s time we stop talking and get serious about improving our nation’s floodplain management by putting these lessons into action.
