This past week, Hurricane Florence pummeled the Carolinas, dumping more than 8 trillion gallons of rain on North Carolina. Floodwaters surged, submerging cars and inundating homes. More than a million people were left without power, and forty-three lost their lives.

Our coastlines and the people who populate them face an evermore daunting issue: planning for sea level rise and stronger storms while minimizing the degradation of coastal environments. Climate change is causing sea levels to rise and storms to become larger and more intense, even as more and more people are calling the coast their home. The elevated human pressure on our coastal environment, coupled with the dangers of climate change, create the momentous challenge of making our coastlines more resilient.
A decade of powerful storms like Florence has made clear what’s at stake. In 2004, Hurricane Katrina showed us how poor disaster response and racially motivated urban planning results in catastrophe and loss. Hurricane Sandy pummeled New York City and the Mid-Atlantic seaboard in 2012, with disastrous impacts on infrastructure. More recently, the 2017 hurricane season brought tragedy and destruction to millions along the Texan Gulf Coast, the Virgin Islands, the Florida Keys, and Puerto Rico.
Across the US, coastal communities, municipalities, and cities are scrambling to make their coastlines more resilient. Careful flood plain management can lead to controlled flooding. Resilient building standards mitigate damage. Dissipation of wave energy through built features like levees or natural features like coral reefs is another option.
As these examples suggest, resilience is multifaceted and depends on both the built environment and the integrity of natural features. Resilient coastlines will never be completely immune to the impacts of climate change. But a combination of strategies can reduce negative impacts and allow communities to bounce back from destruction that does occur.
Despite the urgency to make and implement coastal resilience plans, politics and funding pose barriers to progress. In New York City, for example, revising flood maps poses political and economic challenges, as including more area in the flood zone means millions of dollars more spent.
But just as coastal resilience planning is a game of politics and funding, it’s also a matter of life and death, security and loss, and equity and inequality. Every extreme storm has shown us that social and economic factors make some people more vulnerable to extreme weather than others – a form of environmental injustice that could easily be exacerbated by climate change if there isn’t significant action. Fighting climate injustice is key to coastal resilience.
Through my beat, I plan to explore coastal resilience strategies that integrate structural engineering, environmental protection, and climate justice. How are communities, towns, and cities creating innovative and comprehensive resilience plans? What barriers do they face? To what extent is environmental justice incorporated in coastal resilience efforts? In what ways can promoting environmental justice improve resilience? Coastal resilience is as much an engineering problem as it is a justice problem. For millions, their economic security and sense of place and home is at stake.
