If It Keeps on Rainin’

 

Difficult as it may be to find a silver lining to all the flooding brought on in the mid-Atlantic states by Hurricane Florence, there is something to be said for how flooding can rejuvenate soils, replenish groundwater, and also bring home to some people the foolishness of their ways. It’s terrible that poor people lost their homes because they have few options available for where they build them or, in the case of mobile homes, park them. The wealthy people who built expensive beach front properties should have less cause for sympathy from the rest of the population.

 

The newer difficulty with hurricane damage is due to the effects of global warming, and that is the rising problem of inland flooding. It used to be that the primary problems caused by hurricanes were storm surge along the coast and wind damage everywhere until they weakened upon moving inland. Lately, sluggishness in a warmer atmosphere causes more hurricanes to stall over land, where they drop upwards of tens of inches of rain inland over the course of days. Hurricanes now are less likely to move quickly after landfall, dropping less than ten inches of rain on inland locations.

People who haven’t foolishly spent riches on beachfront property within feet of harm’s way, people who have instead built their houses inland on properties well away from the dangers of storm surge, now find themselves nevertheless dealing with catastrophic flooding as hurricanes dump tens of inches of rain over their inland homes, overwhelming the capacity of present infrastructure to cope with those intense events. What are these reasonable people to do?

Kansas Joe McCoy and Memphis Minnie perform their original song “When the Levee Breaks” in 1929, a song which refers to the Great Mississippi Flood of 1927. Led Zeppelin performed their own altered version of the song in 1971, and that version has since become the most well known.

They can’t fight rising water; to try is futile. The best they can do is to to work with the water and give it a place to go. Levees don’t work without spillways. Paying attention to where the high ground is always pays off in emergencies, and it’s interesting how many people, divorced as they are from nature, fail to include it in their calculations when buying or building a house. Poor people often don’t have that luxury. Wealthier people, who have options, should not be bailed out by everyone else when their expensive houses slip underwater. The days of not taking severe weather events into account when choosing where to live are over. Escaping the effects of severe weather will be impossible, however, as people who have been flooded out of their inland homes hurricanes now know, and that leaves taking sensible measures to cope with the consequences of global warming in order to go on living.

Bugged Out

 

The eastern half of the country has received copious rainfall this spring, and in the eastern seaboard states the rainfall has been excessive, leading to flooding in spots like Ellicott City, Maryland. The high rainfall amounts have led to a greater than usual amount of standing water, and because mosquitoes lay their eggs in standing water there is a greater than usual mosquito count in the eastern United States. There was also a mild winter preceding this spring, and that has led to high counts of ticks and other insects. People who want to spend more time outdoors as the weather warms this year must be prepared to either defend themselves or succumb to getting their blood drawn by numerous insects, taking a chance consequently on coping with a disease for which the blood sucking insects are vectors.

There are the usual recommendations from experts to cover up when outdoors in the summer when insects are most active, but it’s awfully tough to take their advice when it’s 90 degrees and the humidity is very high. Long pants tucked into high socks? Long sleeves on shirts? In order to stay comfortable, many people won’t heed that advice. The advice to wear loose fitting, light colored clothes is welcome, however, because in addition to coping with insect attacks that advice helps the wearer cope with hot weather. Above all, in more ways than one, the most important item of clothing in summer is a broad brimmed hat.

A good quality broad brimmed hat will serve to ward the sun off a person’s face, neck, and ears, as well as absorb sweat before it runs down from brow into eyes, and in addition will help keep insects away from one’s head. The last statement is based on nothing more than anecdotal evidence, but test it for yourself in the course of wearing a broad brimmed hat for all its other useful qualities. Insects seem reluctant to come up under the broad brim. Is it 100% effective? No, but then very few things are 100% effective in life. Toss away that useless baseball cap and try wearing a broad brimmed hat like a boonie hat. Bucket hats, the diminutive cousins of boonie hats, do not count.

For those who would rather resort to what they believe are the more certain results yielded by chemical insect repellents, there are the usual products readily available at most stores. Try not to go overboard. Before buying those clothes soaked in permethrin, consider eating more garlic and onions as a systemic repellent to ooze out of your pores for a day or two at a time, scaring off bugs and people alike. Botanical repellents are generally less effective than their more renowned chemical cousins, but they also leave a lighter footprint on the environment and perhaps on the user.

One product that straddles the border is the permethrin mentioned earlier. Permethrin is derived from flowers related to chrysanthemums, and is not a repellent but an insecticide. When you use permethrin products, insects will land on you and may get an opportunity to suck blood before they die and drop off. A repellent, of course, wards off insects before they land on you. Permethrin is more effective than other botanicals, and is generally safer for the environment and the user than chemical repellents or insecticides. It is used in some flea treatments for dogs. It is not used in flea treatments for cats, however, because it is toxic, even deadly, for cats. People who have both cats and dogs in their homes should keep in mind if they apply permethrin flea treatment to the dogs but not the cats that the permethrin can still adversely affect the cats by secondary contact. For everyone, as tempting as it is to reach for the most highly effective treatment when battling insects which can transmit troubling diseases, or at least cause discomfort, try to maintain perspective so that the treatment doesn’t end up being worse than the affliction.

Powering Down

 

A strong nor’easteror northeaster, if you prefer – is causing havoc along the east coast from North Carolina to Maine and into Canada to kick off the first weekend of March 2018. Nor’easters typically occur in the colder months, almost always in the eastern third of the country, though occasionally slightly farther west, as in November 1975 when a storm whipped up Lake Superior, sinking the SS Edmund Fitzgerald, and they can be as destructive as hurricanes when taking into account the wider swath and longer duration of a nor’easter over a hurricane. Blizzards with heavy snowfall, downpours and consequent flooding, beach erosion, and power outages and damage to houses, businesses, and infrastructure from gale force winds, all can be attributed to nor’easters.

 

The winds of a nor’easter never reach the highest speeds of hurricanes, but even 30 and 40 mile per hour winds in winter can cause trees and tree limbs to topple onto overhead power lines. The ground does not dry out as quickly in winter as in summer, and that can make the difference between a tree staying upright in high winds or falling over. Add the weight of snow and sometimes ice, and not only tree limbs and trees fall, but even utility poles may snap off at ground level. It’s not uncommon then to hear reports during a strong nor’easter, such as the one currently blowing along the upper east coast, of millions of utility customers being without power, sometimes for days.

After every particularly bad storm that causes massive power outages, many people want to know why in this country most of the power lines are still above ground, where they are vulnerable to storm damage. They want to know why more of the lines aren’t buried, seemingly out of harm’s way. The blizzard of 1888 brought New York City to a standstill, and the effect was that city leaders made a determination afterward to start placing essential services underground, in particular building a subway system to help city inhabitants keep moving no matter what the weather. Putting in new facilities at a time when the city was still in the process of being built out to its full potential turned out to be not as disruptive and expensive as it would be today, now that every square mile of Manhattan real estate has something already built on it.

Developers building new upper middle class subdivisions sometimes put the power lines underground because those developments can absorb the extra cost, typically 10 times more than overhead lines, and because the pleasing aesthetics and perceived security of underground lines enhance property values. There are drawbacks, often overlooked, such as the vulnerability of any overhead lines feeding into the new development, and the increased time and expense for power company crews to locate and fix compromised underground lines. One of the ways an underground power line can become compromised is through flooding, in which water or even water vapor will find its way into any vulnerability in the line’s sheathing and short out the line. Lines are usually buried from 24 to 48 inches deep, which in most cases is deep enough to insulate them from digging accidents and the soil water pressure of ordinary rainfall. In floods, however, the soil can become so waterlogged that pressure builds high enough to force its way in toward the power line.

There is no one absolute answer to lessening the risk of losing power during a storm, other than to disengage from the power grid entirely. For those who remain hooked in to the grid, some peace of mind can be had by purchasing a portable generator or installing a standby generator. Power companies should put more of this country’s grid underground in spots where the benefits can be greatest, leaving the rest of it above ground where the costs are prohibitive. Utility customers may wail once again about all the damaged above ground lines once this latest nor’easter has moved on out to the open ocean, but they often quiet down once they hear how much their power bill would have to be hiked and for how long in order to pay for putting the service below ground. The people who have it worst in some ways during a storm and for days or weeks afterward are the power company workers who have to be outside in dreadful conditions doing what is a dangerous job even in sunny, balmy weather, and is many times worse in soaking rain, blowing snow, pelting ice, and winds that could throw anyone off course.

An Ounce of Prevention

 

The American system, and perhaps the American character as well, has always favored coping with the damage from disasters as they come over doing all that can be done beforehand to mitigate the severity of damage. The insurance industry is aligned toward dealing with the aftermath rather than encouraging preventive measures, as is the government, which tends to label regulations designed for prevention as socialist intrusions. It’s the same philosophy that guides the economic system, which is all for free market capitalism on the front end when businesses are making profits for the few, but resorts to socialism on the back end when things go sour and losses are then spread out among the many. “Heads I win, tails you lose,” says the Wall Street tycoon, and friends in government chime in “Yea, verily.”

 

Unrestricted urban and suburban development covers acreage that drained itself adequately with concrete and asphalt that does not absorb water. That seems obvious, and the necessity for a drainage system capable of handling all the runoff also seems obvious. Certainly there are some events, such as the unprecedented rainfall in Houston from Hurricane Harvey, that would stretch any drainage system to the breaking point. Extraordinary events require extraordinary preparation, a methodology well known among engineers, who are trained to design and build structures and systems to withstand the extraordinary. Engineers’ best efforts can be hamstrung, however, by ideologically and greed driven government leaders and business executives, the effect of which can be seen when disaster strikes and destruction of life and property is greater than it needed to be.

The acknowledged masters of hydro engineering, the Dutch, have recently changed their philosophy about coping with excess water from staving it off to flexing with it. Bend, to keep from breaking. That has always been the way with nature, of course, where coastal wetlands have served to absorb the brunt of ocean surges, and where floodplains served as safety valves for swollen rivers. Holding water back with fortifications has always been expensive and unreliable. Water is relentless, and it will find a way.

Creating concrete and asphalt jungles willy nilly without regard to anything other than the almighty dollar is foolishness, and ultimately a price will be paid. In the American system, unfortunately, that price is often borne by the society as a whole, and especially by the poor, but certainly not by the wealthy or by the government leaders who created the mess. Breaking up the concrete and asphalt jungle with permeable pavement, a construction practice that has been around for over fifty years and needs to be used more widely, is one way to forestall some urban flooding. Installation costs for permeable pavement are higher than the traditional kind, but it has other benefits and cost savings that offset the higher up front price tag. It’s not a perfect solution, but nothing can be. It’s a step in the right direction.

One of the arguments some business people and their mouthpieces in government often advance against green methods applied to development are that they create too much red tape, leading to a bad environment for business and a net loss of jobs, besides being downright socialist, which of course is an accusation that is supposed to make all the Greens (environmentalists, tree huggers – choose your own epithet) run away and hide themselves in shame. Too bad. If the true costs of bad environmental practices were borne by the businesses and governments that engage in them, they would change their tune.

A 1974 song written and sung by Randy Newman about the Great Mississippi Flood of 1927, and about American society.

If businesses paid their workers a living wage, fewer of those workers would need to rely on government assistance to make ends meet. If businesses that made money here and took advantage of the national infrastructure were required to have corporate offices here, and therefore required to pay their fair share of taxes to help support infrastructure improvements, then maybe the country wouldn’t be falling apart while a select few get obscenely rich at the expense of everyone else. If, in other words, we stopped allowing some businesses and their allies in government to slough off hidden expenses on society at large, we could make progress toward a less dangerous future. But it’s going to take a change of heart, of character, to turn this backwards system around and look at green development as the only sensible way forward for everyone, instead of being led by the nose by those whose view of development looks backwards and serves only themselves.
