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 »

Attention Congress: Investing in nature can help our flood-ravaged nation

By Shannon Cunniff / Bio / Twitter profile / Published: June 17, 2019

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 »

Three ways nature can help rebuild and protect communities following Cyclone Fani

By Devyani Kar / Bio / Published: May 31, 2019

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.

Army Corps releases crucial guide for reducing flood risk and increasing resilience

By Shannon Cunniff / Bio / Twitter profile / Published: January 16, 2019

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 »

How to accelerate the use of natural infrastructure to aid climate change adaptation

By Shannon Cunniff / Bio / Twitter profile / Published: November 7, 2018

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.

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 »

Less talk, more action: It’s time to get serious about floodplain management

By Shannon Cunniff / Bio / Twitter profile / Published: May 16, 2018

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.

4 ways to strengthen coastal communities’ resilience before the next storm

By EDF Staff / Published: April 12, 2018

This blog was authored by Shannon Cunniff, with contributions from Kate Zerrenner.

The 2017 hurricane season sounded the alarm for coastal communities across the country and across the world that are facing increased exposure to powerful storms.

Nearly 40 percent of the U.S. population lives in coastal counties, where hurricanes are often the most destructive weather phenomena bringing rain, wind, waves and storm surge that too often result in significant loss of life. With a changing climate, we can expect more extreme weather. But we don’t have to expect the same levels of devastation.

There are steps we can take to decrease coastal communities’ vulnerability to storms, lower the risk of damaging floodwaters, and reduce the impacts associated with these disasters. Read More »

Will we be prepared for the next natural disaster? Let’s make sure the answer is “Yes.”

By Paxton Ramsdell / Bio / Published: April 5, 2018

It’s hard to believe it’s been nearly a year and a half since Hurricane Matthew delivered devastating floods across eastern North Carolina. With so many families and communities still recovering from that storm, the thought of having to prepare for the next one is daunting, but it’s a necessary reality.

This month, a group of North Carolina state legislators will convene in Raleigh to discuss how to spend the state’s remaining federal disaster relief funds provided in the wake of Matthew.

In addition to the needs of still ongoing recovery efforts, the North Carolina House Select Committee on Disaster Relief is expected to begin exploring investment opportunities related to flood control and risk mitigation. Read More »

The hidden opportunity for water storage in California

By Maurice Hall / Bio / Published: June 1, 2017

California’s historic winter ended the drought in many parts of the state and piled up record levels of snowpack in the Sierra Nevada Mountains. With so much precipitation, surface water infrastructure – our network of dams, reservoirs and levees – has been called into action like never before, and in some cases has struggled to handle the influx of flows.

With spring temperatures on the rise, snowmelt and runoff have accelerated, adding another wave of stress to the system. And with snowpack still at 192% of average, there is even more runoff on the way.

So where will all this water go?

With many reservoirs near capacity already, water managers have had to allow spring snowmelt to flow out through the Sacramento-San Joaquin Delta and into the ocean. This is inevitable given the sheer amount of water in the system this year, and in fact, these occasional high flows provide multiple benefits to ecosystems and coastal communities.

What it’s going to take to fund California’s water infrastructure

By Pablo Garza / Bio / Twitter profile / Published: March 6, 2017

Central Valley's levee system is damaged and needs repair

Crews are working to repair damage to the Central Valley’s levee system.

The situation at Oroville Dam garnered national attention and brought into clear focus the limitations of our aging flood protection infrastructure – California’s complex system of dams, levees, and bypasses – as well as the need for greater investment in maintaining and upgrading this system.

It is appropriate, then, that Governor Brown recently unveiled a plan to bolster dam safety and flood protection. By requiring emergency action plans, beefing up our dam inspection program and increasing our investment in emergency response, Governor Brown is taking an important first-step in tackling this difficult problem.

This comes at an especially important time as infrastructure maintenance is at the forefront of state and national discussions, and we still have a few months to go before we are out of the rainy season.
