Catastrophic Floods More Frequent in 2019

Last week, after already experiencing heavy rainfalls and flooding, New Orleans was preparing for tropical storm Barry, expecting the storm to overflow or even breach the city’s levees. Flights in and out of the city were cancelled, as were concerts and other public events, as the city braced for catastrophe. Barry ended up narrowly missing New Orleans, and instead moved inland, drenching other parts of Louisiana and Mississippi and causing floods and mass power outages in those areas. It was yet another example of how major flooding has become a normal occurrence for many regions of the country, and by all indications, it is becoming worse each year.

The National Oceanic and Atmospheric Administration (NOAA) stated in its report 2017 State of U.S. High Tide Flooding and 2018 Outlook that “The projected increase in high tide flooding in 2018 may be as much as 60 percent higher across U.S. coastlines as compared to typical flooding about 20 years ago and 100% higher than 30 years ago.” This prediction turned out to be accurate, as the United States saw massive flooding throughout 2018, including “sunny-day” or “high-tide” flooding that occurs during high tides outside of hurricane events.

In its recent report on 2018 high-tide flooding and 2019 outlook, the NOAA said that these floods’ median frequency in 2018 “reached 5 days, which tied the historical record of 2015.” Of the 98 observed locations along the U.S. coastline, 12 reportedly broke or tied their all-time records for high-tide flooding in 2018. And now, the NOAA is predicting that 2019 could be even worse.

The NOAA noted that high-tide flooding “is increasingly common due to years of relative sea level increases. It no longer takes a strong storm or a hurricane to cause flooding in many coastal areas.” The Union of Concerned Scientists has said that sea level rise is accelerating, that “sea levels in the U.S. are rising fastest along the East Coast and Gulf of Mexico,” and that the primary reason for this sea level rise is climate change melting land ice and heating oceans.

According to the NOAA’s 2019 projections, it expects high-tide flooding along the U.S. coastlines this year to reach double the numbers from 2000. Additionally, “the Northeast Atlantic could see a 140% increase, the Southeast could see a 190% increase, and the Western Gulf of Mexico could see a 130% increase.”

Almost 40% of the U.S. population lives in coastal areas, and could be at risk from flooding effects. With the start of hurricane season, these dangers will only increase as storms batter the coasts. Even before Barry threatened, New Orleans faced massive flooding last week, while Pittsburgh contended with flash floods. And the week before, heavy rains left Washington, D.C. and surrounding towns swimming in water that overwhelmed the city’s storm water pipes.

These increasing floods mean serious losses for people, municipalities and businesses. The recent DC-area floods reportedly caused $3.5 million in damage to Arlington, Virginia county infrastructure alone. In March, a “bomb cyclone” hit Nebraska, with heavy rainfall causing damages totaling more than $1.3 billion. This figure includes $449 million in road, levee and other infrastructure damage, as well as serious damage to more than 2,000 homes and 340 businesses. Iowa also experienced flooding that caused water treatment plants to shut down, depriving two cities’ residents of fresh water. And across the Midwest, agriculture was also hit hard by flooding, slowing corn and soybean planting. The delay may decrease harvests by at least 8% and increase prices worldwide.

As Risk Management Monitor has previously reported, Texas A&M University at Galveston and the Texas General Land Office examined the 50-year impact of a major storm hitting Galveston Bay on the Texas coast near Houston, finding that major storm events that caused flooding would have huge secondary effects on the economy, both locally and nationally.

Various states, including those along the Mississippi River, have already enacted flood control measures like levees, dams and flood walls, but have seen this year’s increased flooding defeat these measures. Others have encouraged residents to purchase flood insurance to offset losses. But the increasing scope of future floods may mean that these steps are not enough. Though tropical storm Barry missed New Orleans, experts have still expressed concern about coming storms possibly “topping” the city’s levees, which could cause even more damage to the already-flooded city.

Texas Study Shows Business Impact of Major Storms

A new study conducted by Texas A&M University at Galveston and the Texas General Land Office examines the 50-year impact of a major storm hitting Galveston Bay on the Texas coast near Houston, including secondary effects to the economy. The study focused on catastrophic “500-year” flood events (with a one-in-500 chance of occurring in a year), which, while rare, have hit the state 3 times in recent years. This includes Hurricane Harvey, which struck Louisiana and Texas in August 2017, causing $125 billion in damage, according to the National Hurricane Center.

These larger storms have serious economic impacts locally, regionally and nationally. Over a 50-year time frame, the study notes, “the projected economic impact on Texas’ Gross State Product (GSP) of storm surge without coastal protection is substantial.” In the wake of a 500-year magnitude event, the regional petroleum and chemical manufacturing sectors would see their output decline by 19% (or $175.4 billion) in lost revenue, as well as a projected 17% loss of petroleum jobs (approximately 155,000 jobs) and a petroleum price increase of 13%. It would also impact the region’s housing, with the sector declining by 8%, or $39.5 billion lost in sales.

A 500-year surge event striking Galveston Bay would also have serious impacts for national economic activity, especially because the region processes 25% of the petroleum and more than half of the jet fuel used in the United States. According to the study, U.S. GDP could drop 1.1% (approximately $883 billion), U.S. exports would suffer a 4% drop (approximately $1.66 billion) and “30 states not including Texas will have lower GSP in response to a surge event in Texas.”

“The Galveston Bay region is one of the most flood- and surge-prone areas in the United States with vast amounts of vulnerable residential, commercial, industrial and petro-chemical areas at risk,” said Texas Land Commissioner George P. Bush. “This study clearly demonstrates that, without any new protections in place, future storm surges could have substantial and lingering impacts on Texas’ economy and send lasting ripples through other economic sectors nationwide.”

Turning to mitigation, the authors of the report assessed the potential measure of a 17-foot “coastal spine,” also called a “coastal storm suppression system,” made up of “connecting seawalls and fortified dunes/levees along the coastline to retractable gates.” In October, the Army Corps of Engineers released the study Coastal Texas Protection and Restoration Feasibility Study proposing a similar example of this sort of structure—74 miles of barrier, including “floodwalls (inverted T-walls), floodgates (both highway and railroad floodgates), seawall improvements, drainage structures, pump stations, and surge barrier gates.”

The researchers estimate that a coastal spine would reduce the region’s lost petroleum and chemical manufacturing sector losses to 3% and 5%, respectively, a 1% reduction in regional unemployment, and a 1% increase in petroleum product prices. The report also claims that a coastal spine mitigation plan would reduce Houston-Galveston regional insurance premiums by as much as 28%. This could provide significant relief for insurers as well. Even though insurance and reinsurance only covered about 30% of the total wind and flood damage from Hurricane Harvey, this amounted to tens of millions in losses.

In terms of construction cost, the Texas researchers polled residents of three local counties and found that 56% “believed that both government and port industries should be responsible for financing the coastal barrier system,” and a majority agreed that some form of taxation should support its construction.

Press Release: RIMS Commends Congressional Foresight to Extend Flood Program Prior to Government Shutdown

National Flood Insurance Program May 31st Extension Avoids Dangerous Lapse in Coverage

NEW YORK – In the waning hours prior to the U.S. Federal Government’s partial shutdown, RIMS, the risk management society™, welcomed congressional action to extend the National Flood Insurance Program (NFIP). Extended through May 31, 2019, the program will become the responsibility of incoming House Financial Services Chairwoman Maxine Waters (D-Calif.) to draft a longer-term reauthorization.

A long-term reauthorized NFIP bill would provide critical financial support to a wide range of businesses experiencing flood emergencies and continues to be a RIMS legislative priority. The NFIP was the focus of the Society’s 2018 Legislative Summit held in October in Washington, DC. Additionally, this November, RIMS signed a joint letter with other insurance, real estate and banking organizations, urging Congress to take immediate action to avoid a lapse in the program.

“Business leaders, especially those located in areas of the country most susceptible to flood disasters, can breathe a sigh of relief knowing that an NFIP lapse has been avoided,” said RIMS CEO Mary Roth. “While RIMS is happy that the NFIP received an extension, the Society will continue to work diligently with elected officials, offering our support to help create a more permanent, long-term solution.”

RIMS’ Political Action Committee (RISK PAC) has been soliciting donations to allow the Society to continue to engage and support Members of Congress who have demonstrated their commitment to the reauthorization of the NFIP. For more information about RISK PAC or to donate, visit www.riskpac.org.

Q&A: Resiliency in India

The 2018 Lloyd’s City Risk Index was analyzed during the RIMS Risk Forum India in Mumbai, and it notes a possible turning point for the subcontinent’s cities regarding resiliency. In short, Indian cities were rated as weak, but recent government and public investments and campaigns that focus on strengthening infrastructures and people may strengthen those assessments.

During a November 14 morning session, “Assessing the Impact of Natural and Man-made Threats on India’s Economy,” Shankar Garigiparthy, country manager and CEO of Lloyd’s India discussed how much economic output (GDP) cities in India could lose annually as a consequence of various types of rare risk events – such as the Kerala floods this past July – or from more frequently occurring events such as cyberattacks.

He discussed with Risk Management Monitor reasons why he is hopeful for a resiliency turnaround in India and how the combined wills of the government, media, public and business can strengthen the country’s infrastructures and ultimately, its risk ratings.

RMM: How do India’s cities rank in Lloyd’s City Risk Index?

SG: Lloyd’s City Risk Index was published three months ago and we researched 279 cities. We found that a vast majority of cities within the subcontinent of India have been rated as very weak from a resilience point of view. They are at high risk for flood, geopolitical security, market crash, just to name a few.

RMM: What steps are being taken to improve the collective resiliency?

SG: What we have seen in last three or four years is a significant level of investment from the government in terms of building infrastructure. It’s been in the form of roads, bridges, railways, ports, and airports, there has been a significant level of investment. And it seems there is more to come. In the budget, the government has announced more – which is encouraging to see from an infrastructure-building point of view.

However, where we still see a bit of lack is in the area of insurance penetration in the country. That’s where I think insurance companies can be a useful partner and tool to mitigate some of the level of these risks.

RMM: Could this be a chance for insurers to get in on the ground floor of India’s improvement projects?

SG: Yes.

RMM: What incidents have influenced the government to act?

SG: The Chennai floods [in 2015] and the floods in Kerala [in July]. That was a once-in-a-hundred-years occurrence. The entire state was flooded, which I think was the first of its kind. It was completely underwater.

Similarly, the Chennai floods marked another major event. Since then, monsoon has happened but the level of flooding has been managed pretty well.

In the session, we examined the Mumbai floods in 2005. And even last year, there was flooding here for a day, but within a day the water receded pretty quickly and was pumped out. The machinery kicked in and we were able to get out of it pretty well.

RMM: What led to that success?

SG: It was a combination of low tide and the government investing in the necessary pumping mechanisms to actually pump the water back into the sea, and unclog some of the stormwater drains as well. Steps are being taken, slowly but steadily.

RMM: What other institutions are taking measures to build resiliency?

SG: There are a few companies [which I won’t name] that are leading the way and it is encouraging to see that.

The media is also equally playing a fairly significant role as well. That’s also helping because public awareness is something that is critical. The media is raising awareness in terms of the importance of protecting your infrastructure and environment and the need for trees and planting.

RMM: Would you agree that the will to change and improve existing infrastructures is as important as the funding?

SG: I think it’s all there. The government has shown willingness to improve infrastructure. The people have demanded it, so there is a push and a pull coming from both sides. And we are seeing that development happen. Compared to where we were five or ten years ago and where we are now, there’s been a massive change.

There is still more that can be done. I’m not saying that we’re there yet. But it’s not an easy thing, as well.

Given India’s geography and how the political scenario is within the country, we will always be exposed to natural catastrophes. Flooding is going to be a constant phenomenon for us.

There is investment being done but it’s patchy. In some states there has been fantastic infrastructure investment and in others, less so. I think that has got to be addressed and that’s where the public [should be] demanding more actions there, where infrastructure investment has not been up to the mark.
