A Cold Reality Check On Harvey — And The Next Time

From zoning laws and insurance polices to the realities of climate change, there are ways to prevent such widespread suffering. But it requires political will.

Searching for survivors in Houston

Paul J. Ferraro

My heart goes out to the people who have borne the brunt of Hurricane Harvey and still face continued flooding and a long recovery. As a nation, we need to be better prepared for such catastrophic floods so as to mitigate their widespread damage and loss of life. Harvey's 50 inches of rain in a few days might be unusual, but extensive flooding with its subsequent property damage and loss of life is not.

It's time to stop using the words "unprecedented" or "one in a pick-your-large-number-year flood" to fool ourselves into believing that we're experiencing one-off disasters that can't be defended against. We have the tools to prepare, if we're bold enough to use them.

First, stop building and rebuilding in areas that experience repeated floods. This requires political backbone both locally and nationally, because the incentives involved are misaligned. Local governments set zoning rules and collect the property taxes, and local builders profit from construction. But neither of these groups pays for rebuilding after a flood. Taxpayers elsewhere do, through state and federal disaster assistance.

Behavioral biases put lives in danger

Texas's relatively lax zoning laws and building codes have helped keep housing prices low and the population growing. But this shifts the full costs of building onto others. To help align local and national incentives, the federal government should publish a list of the local governments that allow or encourage building in flood zones.

Second, manage storm-water runoff by investing in green infrastructure and traditional engineered controls (such as detention ponds), and cut back on surfaces that are impervious to water. Harris County,where Houston is located, has underinvested in such improvements even though it experiences repeated floods. As its population has grown, the county has lost a substantial amount of its wetlands, which traditionally soaked up storm-water runoff. The county compounded this loss by allowing unrestricted expansion of impervious surfaces.

Third, discourage the two behaviors that cause problems in flood-prone areas: widespread refusal to buy flood insurance, and a general unwillingness to evacuate. Only about one in 10 homes in Harris County has flood insurance. In other flood zones throughout the U.S., as well, homeowners lack flood insurance, even as almost all of them are insured against fire — a much lower risk for them. Better communication with such homeowners, by both governments and insurers, could help increase take-up. But change will be slow to come as long as homeowners are permitted to forgo insurance and then receive grants for rebuilding.

Behavioral biases — overconfidence in good fortune, for one, and an inability to understand risk and probabilities — also put lives in danger. Too many decide at the last minute to "wait it out." Hurricane Harvey's dire forecast came two days in advance. Government evacuation operations that need to focus on citizens who are immobile should not be overwhelmed by the needs of those who had the wherewithal to evacuate. An emergency law forcing regional hotels and shelters to take pets might go a long way toward improving future evacuation rates. In the face of a hurricane, the government needs to be able to impose emergency rules.

Fourth, and finally, government leaders must face the science of climate change and the reality that extreme weather events are likely to occur more often. In and around Houston, over the past three decades, the frequency of intense downpours has nearly doubled. One cannot know whether the changing climate has made this one single weather event more intense, but an increased frequency of extreme storms is entirely consistent with expectations. Climate change denial prevents people from taking appropriate steps to adapt to the new reality.

Storms like Harvey will be destructive in unpredictable ways, despite the best preparations. But local, state and national leaders have the responsibility to see that Americans are ready and that damage and loss are kept to a minimum.

First It Was Poland's Farmers — Now Truckers Are Protesting Ukraine's Special Status

For the past month, Poland has been blocking off its border checkpoints to Ukrainian trucks, leaving many in days-long lines. It's a commercial and economic showdown, but it's about much more.

Since November 6, Polish truckers have blocked border crossing points with Ukraine, citing unfair advantages given to the Ukrainian market, and demanding greater support from the European Union.

With lines that now stretch for up to 40 kilometers (25 miles), thousands of Ukrainian truckers must now wait an average of about four days in ever colder weather to cross the border, sometimes with the help of the Polish police. At least two Ukrainian truck drivers have died while waiting for passage into Poland.

The round-the-clock blockade is being manned by Polish trucking unions who claim that Ukrainian trucking companies, which offer a cheaper rate, have been transporting goods across Europe, rather than between Poland and Ukraine. Since the beginning of Russia’s invasion, Ukrainian truckers have been exempt from the permits once required to cross the border.

Now, Polish truckers are demanding that their government reintroduce entry permits for Ukrainian lorries, with exceptions for military and humanitarian aid from Europe. For the moment, those trucks are being let through the blockade, which currently affects four out of Ukraine’s eight border crossings with Poland.
