The impact of storm surge barriers on estuaries and ecosystems

By Guest Author / Published: August 22, 2023

By Philip Orton, Research Associate Professor, Stevens Institute of Technology

Due to the increasing frequency and risk of coastal storms and flood disasters, many governments and decision makers are looking to construct gated storm surge barriers.

The U.S. Army Corps of Engineers is recommending these large steel and concrete barriers be built across entrances to 11 U.S. estuaries, enabling closure during storm surges to minimize coastal flooding. However, many scientists are wary of the potential effects these barriers could have on coastal ecosystems, leading many advocates to push for a precautionary approach or their outright rejection.

Published in the scientific journal Earth’s Future and supported in part by funding from Environmental Defense Fund, colleagues and I recently formulated a new research agenda focused on the intersection between the increased use of storm surge barriers and the resulting estuary impacts. These are three key takeaways from our research:

Why every state needs a Chief Resilience Officer

By Guest Author / Published: July 28, 2023

By Makenna Cavanaugh, Federal Affairs Intern, Climate Resilient Coasts and Watersheds

Communities across the country are grappling with the whiplash of flooding and extreme storms as the frequency and severity of climate hazards reach unprecedented levels. From economic instability to safety hazards, to inequities and the destruction of entire neighborhoods, these events have proven to have devastating and lasting impacts. And one thing is made clear – we need real, robust solutions and we need them across all levels of government to protect communities and promote long-term sustainability.

Some states have acted by establishing a Chief Resilience Officer (CRO), a government position that is responsible for spearheading resilience coordination and bringing together stakeholders to build, develop and implement resilience strategies. Creating a state-level CRO helps leaders effectively plan at the state, county and municipal level and is a major step forward in protecting communities from future climate impacts.

Currently, 21 states have an established resiliency office or position at the state level. Among them, 11 states have a CRO. Read More »

Hurricane season is here again. And finally, leaders are addressing multiple flood risks.

By Natalie Snider / Bio / Twitter profile / Published: June 9, 2023

Every year hurricanes present a variety of threats to communities along the Atlantic and Gulf of Mexico coasts. And these risks aren’t just from storm surge.

Harvey and Ida showed us the effect of heavy rainfall, while Hurricane Florence demonstrated how rivers can overflow into homes and businesses. Meanwhile, climate change is impacting sea level rise, which increases sunny day flooding and the trauma caused from storm events.

Flooding doesn’t just impact coastlines, it impacts entire communities both inland and by the water. It hinders parents’ ability to bring their children to school and it limits patients’ access to vital healthcare and medical services. Not to mention, flooding has inequitable impacts on the wealth, health and wellbeing of millions of families.

As we enter into the 2023 hurricane season, we’re reminded of the urgent need to implement natural disaster mitigation strategies that address comprehensive flood and storm risks. Acting before the next storm strikes means protecting both communities and ecosystems, in addition to saving nearly six times the cost spent on disaster recovery.

The good news? Over the past year, leaders have responded to our call to act – a call that was supported by more than a hundred organizations around the country. Here are two major ways their efforts can prepare us for the next hurricane: Read More »

Climate-driven floods could displace millions of Americans. Local buyout programs could help them relocate.

By Guest Author / Published: May 23, 2023

By Kelly Varian, Master of Public Affairs Student at UC Berkeley

Flooding is the most frequent and costly natural disaster in the United States, causing over $30 billion in damage annually, with disproportionate effects on low-income communities. With climate change exacerbating flood risk and population growth continuing in high-risk areas, over 40 million Americans living along rivers and inland floodplains, along with 13 million more on the coasts, could see their homes inundated with water by the end of the century.

Prioritizing communities and nature in the nation’s largest Army Corps project in New York-New Jersey Harbor

By Kate Boicourt / Bio / Published: May 8, 2023

A plan for the largest transformation of New York City’s and northern New Jersey’s waterfront since the Robert Moses era has been proposed by the U.S. Army Corps of Engineers (USACE). It’s called the New York-New Jersey Harbor and Tributaries Study and it was introduced to the public to address flooding and storms like Hurricane Sandy. At stake is the future of more than 84 miles of waterfront and waterways in the metropolitan region and an area that supports 16 million people.

New York and New Jersey residents must determine if this $52 billion dollar plan aligns with the future they want. Addressing flood risks is a step in the right direction, but as it stands today, the current proposal does not reflect the priorities of many communities and environmental organizations. With the impacts of climate change already in motion, we simply cannot afford to get this wrong. Read More »

Five recommendations for integrating equity into benefit-cost analysis for flood risk management

By Dave McLaughlin / Published: April 28, 2023

When making any decision, we often find ourselves weighing the pros and cons of an action – the benefits versus the cost. The official practice, referred to as “benefit-cost analysis,” is not only used by individuals and businesses, but also by the federal government when determining funding for a program or initiative. In simple terms, when the benefits exceed the cost of an investment, federal funding may be made available.

But oftentimes benefit-cost analysis doesn’t look at the full picture, neglecting to consider who benefits from an investment and who bears the brunt of its cost. This is true when examining the nation’s flood risk management strategy. Historically, the annual loss from flood damage disproportionately impacts low-income communities and communities of color, leaving those with fewer resources less protected.

50 years is too long! Now is our time to go bold or go home.

“50 Years is Enough!”

That was the theme at this year’s 8^th Annual Historically Black Colleges and Universities (HBCU) Climate Change Conference in New Orleans. 50 years of indiscriminate toxic dumping, 50 years of hazardous waste sites in frontline communities, 50 years of land-use decisions that harm communities of color – enough! It’s a searing message for attendees and a reminder that shines a light on the emergence of the movement from the 1960s and 1970s, in reaction to discriminatory environmental practices.

The conference began with a painful trip down memory lane, focused on the trials of environmental racism that befell Black communities in the 1960s. Event organizers discussed how imperative it is for policymakers to act in a way that helps ensure that communities have agency and ownership of their own future. The conference highlighted the long history of systemic racism that lies behind the environmental injustices that communities have faced for so many years. It also fueled a fire inside the movement’s trailblazers who spoke at the conference, forcing them to declare that enough is enough. We are fighting back! Read More »

New Army Corps guidelines will expand natural infrastructure to reduce flood risk and more

By Natalie Snider / Bio / Twitter profile / Published: October 19, 2021

This year has brought devastating flooding in the Netherlands, Germany, China, the U.S. and elsewhere. Globally, over 2.2 billion people are exposed to flooding, and that number is growing.

New research indicates the proportion of people living in floodplains since 2000 has increased by 20% to 24%, and climate change is further increasing flood risk with rising sea levels, more intense storms and extreme rainfall events. We need urgent action to protect people from these growing risks.

To this end, the U.S. Army Corps of Engineers (Corps) just released their “International Guidelines on the use of Natural and Nature-Based Features (NNBF) for Flood Risk Management.” Here’s why that’s a big deal.
