Scientists say Hurricane Harvey was a 1000-year flood event, considered so rare we are unlikely to see anything like it for some time. However, there is a chance, albeit a small one, that the U.S. could see a storm of that magnitude again this year.
Consider other memorable storms. Hurricane Andrew, which devastated Florida and the Carolinas in 1986, was called a 100-year event. In 2005, Hurricane Katrina, another 100-year storm, flooded New Orleans. Sandy, the hurricane that famously flooded New York City in 2012, was dubbed a 700-year storm. After Harvey rolled through Houston last year, 100-year-storm Irma brought historic flooding to the Florida Keys and Gulf Coast.
A common misconception is that these seemingly rare events can only happen once in a given period of time. Using this logic, a 1,000-year flood is an event that occurs just one time in 1,000 years. In fact, a 1000-year flood actually has a 1 in 1000 chance, or a .1 % probability, of happening in any given year.
So, should we plan for another catastrophic flood event in the U.S. this year?
The answer lies in understanding the probability of natural hazard events. According to the National Weather Service, the probability of another 500-year flood this year in Houston is .2 % or 1 in 500. NWS explains, “If a 100-year flood event occurs, that does NOT mean that people are ‘safe’ for 99 years. The risk of having the flood in any given year is the same.”
To understand probabilities for a 100-year flood, roll the dice.
If the chance of rolling a 6 is 1/6, what happens if you roll the dice six times? Does it equal a 100% chance? It is better to consider your chances of not rolling a 6, or 5/6. Instead of counting all the possibilities, simply multiply the chance that the roll will not be a 6 by the next chance it will not be a 6 and so on. Using the equation 5/6 x 5/6 x 5/6 x 5/6 x 5/6 x 5/6, you can determine the chance that you would not roll a 6. Subtract that number from 100% to determine the probability that you would roll a 6 in six attempts. The number is 66.5%, not 100%.
Using this logic for a 100-year flood, you can see that the chance that event will not happen is 99% for a given year. However, over longer periods of time, there is a greater probability for a 100-year flood (see chart).
Houston should have been ready for Harvey. It had already endured consecutive 500-year floods in 2015 and 2016. The frequency of these so-called “rare” flood events in recent years makes a strong case to plan for events that are unlikely to happen, but can and do happen.
National Flood Protection, LLC offers peace of mind to commercial and residential property owners as they assist consumers in the selection of flood mitigation products. Since 2016, National Flood Protection has been bringing their innovative flood solutions to areas all over the United States devastated by hurricanes, Nor’easters, and severe weather.
“Our objective is to educate customers on the resources they have available to protect their property from flooding” said Russ Ellington, President of National Flood Protection, “as well as stress the importance of doing it now to avoid future catastrophes.” With major flooding events becoming more prevalent, National Flood Protection is proud to represent Flood Panel, LLC – an industry leader in building flood mitigation systems.
National Flood Protection has been traveling the U.S. field measuring for upcoming projects. Their expert team of Architects, Engineers and Installers conduct on site evaluations of buildings using the latest FEMA guidelines to design a project specific plan for protecting a property. “What we’re able to offer is a first line of defense against coastal flooding, rather than remediate the damage caused” explains Ellington. National Flood Protection ensures that not just the flood barrier system openings but also the building structure is able to withstand the hydrostatic and hydrodynamic loads imposed by flood waters.
The cutting edge Flood Panel products greatly reduce structure damage and business operation disruptions caused by severe flooding. “Business owners are looking to safeguard their storefronts, because even just a few days of not being able open their doors can be disastrous to their bottom line” Ellington continued, “Many of the clients we’ve helped are small businesses and they can’t financially survive a prolonged closure.”
As the global climate continues to change and sea levels rise, it has become more important than ever to protect buildings from the damages caused by flood waters, including residences. “National Flood Protection has installed on many hi-rise condo and apartment complexes,” Ellington said, “allowing tenants to not be displaced for long periods of time while their building is being repaired. This also aids in the recovery, so it’s a win-win for the entire community.”
Further, National Flood Protection offers emergency response plans, specific to each individual site. “This is an essential part of the success,” Ellington noted. Each flood mitigation system requires some degree of periodic maintenance and inspection. National Flood Protection, LLC offers each client a Yearly Inspection and Maintenance Plan, ensuring that the building personnel who are tasked with pre-flood event deployment are properly trained and all components are in proper working order.
