We often say that building codes are the foundation for resilience, and today’s new podcast reinforces that message.
This week’s Strong Homes, Safe Families! guest is Edward (Ed) M. Laatsch, Director – Safety, Planning, and Building Science Division of the Federal Insurance and Mitigation Administration (FIMA), Risk Management Directorate – Federal Emergency Management Agency (FEMA).
Ed is a FLASH Founding and Legacy Partner, one of the nation’s leading experts on building science, and a true champion for resilience.
I was honored to serve on the Louisiana Uniform Building Code Task Force that led to creation of the first statewide residential building code more than ten years ago. And, along with our many partners, we support state leaders and the Louisiana State Uniform Construction Code Council (LSUCCC) for creating a system to foster adoption and enforcement of current building codes to ensure the safety and welfare of the citizens of Louisiana.
Unfortunately, it appears that the LSUCCC is on the cusp of a policy decision today that will undermine the effectiveness of that very system created in the wake of Hurricane Katrina. The LSUCCC is one vote away from adopting the 2015 International Residential Code (IRC), amended to remove the minimum one foot of elevated space (or freeboard) in special flood hazard areas. As you might imagine, the state famous as “Bayou Country” has an abundance of low-lying, special flood hazard areas.
Freeboard is the term handed down from nautical engineering where it describes the distance between the deck of a ship and the waterline. The higher the freeboard, the more protected the vessel is from taking on water. The same applies to buildings and homes. Freeboard provides a critical measure of safety and financial protection through extra height in elevation to keep floodwaters shy of the doorstep and out of a home.
Keeping just a few inches of water away is beneficial as it can prevent thousands of dollars of damage to floor finishes, electrical wiring, contents, and more. Two inches of water typically causes $21,000 in damage, and four inches will cost an average of $29,650.
The economic benefit of freeboard is proven, and was demonstrated during the East Baton Rouge flooding in August of this year. According to HUD data, approximately 24,000 of the substantially-damaged homes in that event experienced water less than one foot. This means that the one-foot freeboard requirement would have spared those families and prevented the catastrophic financial losses, disruption, and long-term recovery woes that continue today.
Another financial benefit of freeboard is that elevated structures receive annual flood insurance premium discounts with or without flooding activity. These savings add up over time and offset the initial, additional cost of construction. Further, the only cost-effective time to elevate is during new construction. Elevation after the fact is expensive, and sometimes impossible.
Ironically, it appears that Louisiana building officials are not opposed to freeboard, yet they support this weakening amendment because they prefer local control over a statewide code requirement. But the track record of local control is problematic. Only 33 jurisdictions of the 350 flood hazard jurisdictions in Louisiana have adopted the one-foot requirement. This means that only 10 percent of local officials have put these protections in place—leaving 90 percent of Louisiana residents unnecessarily at risk.
Despite our many partners’ efforts to articulate the overwhelming benefits of this logical, financially-advantageous practice, the LSUCCC seems determined to simultaneously weaken and update their most current residential code. When they do, they will not only deny Louisiana citizens essential safety and proven financial benefits, they will abandon the most effective and responsible disaster resilience action within their control.
By doing so, they are placing the financial burden on taxpayers when the inevitable floods return to Louisiana—a leadership low-point in a low-lying state.
Earlier this year, we launched #HurricaneStrong, a new national hurricane resilience initiative to overcome public amnesia regarding the value of advance storm preparations. We did so because readiness declines when land-falling storms are scarce, and resilience is impossible without a prepared public.
In this video, we make the point that decision-making by the individual or family is one of the most important drivers of safety and survival when a hurricane comes ashore as Hermine did in Tallahassee this month.
So from my perspective as part of both the disaster safety and Tallahassee communities, I am offering an unofficial score card on our Hermine performance by benchmarking against the five key focus areas of #HurricaneStrong. For this analysis, I am labeling actions before, during, and after as either “Resilient” or “Rusty”. And, yes, this is anecdotal, but well-informed as it is derived from our impressions as well as those of our vast network here and across Florida.
1) Personal Safety – Know Your Evacuation Zone – It’s still early, but I can confidently say that with respect to evacuation, the behavior of the majority of those at greatest risk in the path of Hermine was Resilient. The most dangerous life safety threat from Hermine was exactly as forecast by the National Hurricane Center—near record storm surge. And most of the residents of our coastline paid attention, and either hunkered down in elevated spaces, or they evacuated as ordered. As a result, no loss of life in Florida occurred from storm surge when the predictions proved accurate. Regrettably, one life was lost in a tree fall in an interior city, Ocala, but thanks to exceptional forecasting and public messaging from the National Hurricane Center, we averted potential for widespread loss of life.
2) Financial Security – Have an Insurance Check-up – This is one where I have to go with Rusty as many seemed unfamiliar with insurance policy basics. Here are the things you really need to know if you live in hurricane country:
First steps post-storm should be to protect your covered property from further damage, document the losses by taking pictures (before you dispose of property), and contact your insurance company.
Hurricanes may trigger special, percentage deductibles that are usually higher than dollar deductibles, e.g. 2% of a $300,000 home would mean a $6,000 deductible on physical damage to the home.
Loss of Use reimbursement may be available if your home is rendered uninhabitable.
Food spoilage caused by power outage may be covered, typically with a limit of $500.
Tree removal is not covered unless the tree hits a covered structure.
Increased electric bills may be covered if fans and other equipment are needed to dry out a damaged structure.
Temporary repairs are typically covered if they are deemed reasonable and necessary.
Automobile damage is covered so long as your policy includes “comprehensive” coverage.
Flood insurance is not covered under a regular homeowner’s insurance policy, and requires a separate purchase.
Flood insurance policies require a 30-day waiting period, so even in long lead time storms like Hermine, no coverage protection applies until a month goes by.
Flood insurance is critical for families to become #HurricaneStrong as uninsured flooding losses are often the most financially catastrophic byproduct of hurricanes and storms like Superstorm Sandy, the South Carolina “thousand-year flood”, or last month’s flooding in Louisiana.
This is one of the reasons we made insurance a priority in #HurricaneStrong, and why we routinely partner with FEMA’s FloodSmart.gov team to help spread the word. In July, we did so through an appearance on WFTS-ABC Tampa Bay’s “Morning Blend”. This broadcast reached families in the ten-county Tampa Bay viewing area with data like that in the table below:
What this table shows us is that only one-third of those residing in high-risk flood areas around Tampa Bay have a flood policy in force. Further, only five percent of those in low- to moderate-risk areas have a flood policy. This is startling and problematic for a whole host of reasons. As previously stated, life-altering physical and financial losses from floods can haunt families for years. We see this right now in South Carolina where foreclosures and building failures plague many families affected by flooding in Columbia last year.
It is also alarming for low- to moderate-risk areas as floods can occur well away from the high-risk zones, just as they did last month in Louisiana. In fact, 20 percent of all flood claims come from outside the high risk flood zones. One silver lining is that flood policies in those areas are often affordable. My flood insurance policy in Tallahassee is approximately $34 a month.
If you need further convincing, click on this cost of flooding calculator. You will see how quickly the losses add up. Two inches of water in your home will create an average of $21,000 in damages, four inches will cost $29,650. Flooding costs rise almost as fast as the water.
Just imagine what would be happening in Tampa Bay right now if Hermine had turned further east, and those without flood policies had been inundated.
Bottom line? Balanced against the potential cost of flooding, most of us in hurricane country need to make the investment in a flood insurance policy.
3) Family Preparedness – Build a Disaster Supply Kit – The bad news is that this simplest of #HurricaneStrong behaviors earns a Rusty designation post-Hermine. And, I think this is where the amnesia really hurts us. Apparently, many here either didn’t know, forgot, or ignored the basics of family readiness. They didn’t stock up on nonperishable food, water, or ice. They didn’t top off their gas tanks ahead of the storm.
Worse, afterwards, they ventured out too soon for safety. Power lines were sparking, traffic lights weren’t working, and gas station lines were growing by the minute. They showed up at McDonald’s (where they were doing brisk business thanks to a generator), but they couldn’t buy food as they never anticipated the need for cash. Credit cards didn’t work in many spots where the Internet service networks were down.
Food, water, cash, gas—all are “king” post-disaster. So the good news is that this is one of the easiest ways to become resilient. Make the list; secure the supplies. Plan for a generator, and make sure you have gas and oil to keep it running. If you can’t afford a generator, consider cost-sharing a purchase and plan ahead with family or friends to get one residence up and running until power is restored. Remember, those that plan win.
4) Damage Prevention – Strengthen Your Home – The storm surge did cause damage along the coast, and substantially-damaged structures will need to be elevated when they are rebuilt, especially if they want to qualify for future flood insurance.
Conversely, for the most part, the winds were not high or constant enough to reliably test home construction. But they did shine a light on the downside of our love affair with trees.
When we live in a beautiful, canopied area like the Big Bend, trees will topple when the winds blow, but there are things we can do in advance to mitigate impacts. Every year, we need to trim, limb up, and maintain healthy trees. If a tree is dead or dying, we should remove it. Local county extension offices are an excellent source of free expertise to help you decide.
If a storm threatens, and you are staying in your home, you should evaluate where a tree could land on your home and its proximity to sleeping rooms. Many here did exactly that ahead of Hermine, and it was a lively (and morbid) topic of conversation. We can never know if all the families that had trees fall on their houses planned to sleep safely out of the way, but in all but the Ocala case, either by luck or planning, people avoided injury and possible death.
So, overall, I can’t judge this category as either Rusty or Resilient, but I can state the obvious—we are lucky that Hermine sped ashore before she strengthened further. It could have been so much worse.
5) Community Service – Help Your Neighbor – Like the first bucket, I am thrilled to give this one a resounding Resilient. If you know Tallahassee, it should come as no surprise. People here are civic-minded and care deeply about their neighbors. Before, during, and after the storm, Facebook was full of posts with offers to give shelter, share meals, watch pets—anything to help out. When a tree crashed through a roof in one neighborhood, neighbors poured out into the driving rain to help rescue the family.
Post-storm, spontaneous acts of kindness erupted. Businesses gave out free ice, churches gave away hot dogs and cold water in their parking lots, and people opened up their homes to shelter those without air conditioning through some blazing hot days and muggy nights.
Believe me, for the most part, ordinary people behaved valiantly, except maybe the grumpy blogger who unfairly characterized Tallahassee as a community of “whiners” for complaining about power outages. Maybe I hang out with too many social psychologists, but I think he got it all wrong. The Tallahassee “who has power?” social media derby took shape because people were bored, frustrated, and had a way to say so.
“What’s up with my power going down?” is always one of the most common conversations post-storm as it was here for five days with the exception of a few holiday weekend football games (that some couldn’t view without power). With the advent of social media, we just heard more of the conversation, including some truly clever and funny posts.
It may seem trivial from afar that people became obsessed with having electric power, but the outages here caused traffic accidents, disrupted the local economy (many local stores and restaurants remained closed until six days later), and left some elderly sweltering in assisted living facilities.
Later, at the appropriate time, an objective analysis and after-action report will teach us what we might need to do differently to recover more quickly in the future.
So, overall, what has Hermine revealed about our disaster resilience? My score card across the five essential areas include two categories were Rusty, two categories were Resilient, and one was Neither. That won’t get us to #HurricaneStrong. We will never bounce back quickly if we don’t adapt, and get all of these disaster fundamentals right. But, lessons learned here can help us in the next storm, and that’s a good thing.
After all, we still have a lot of hurricane season left to go.
Today is the five-year anniversary of the 5.8M earthquake near Mineral, Virginia—the most widely felt quake in U.S. history, with shaking from New England to Chicago. The temblor damaged heritage buildings including the National Cathedral and Washington Monument, and shook up public perceptions of earthquake geography at the same time.
Since then, leaders have advanced policies that reflect their understanding that seismic risk is a national problem, not just a West Coast concern. One shining example is the new seismic standard for federal buildings showcased by the White House during a resilience summit in February of this year. The Executive Order creating the new standard effectively decreed that government should “walk the talk” with respect to stronger building codes by ensuring that public structures reflect current codes too.
While logical, this was not an easy task, and we applaud those that led the charge.
Also encouraging, there is now progress in the development of a U.S.-based Earthquake Early Warning (EEW) system as well. This is essential as just five to seven seconds of notice before an earthquake could prevent trains from derailing. The EEW system can trigger automatic closure of elevator doors, prevent fire station doors from jamming (trapping needed response vehicles), and it can lower crossing gates for bridges too.
These actions could mean the difference between life and death for thousands in a seismic event.
Equally important, sustained efforts are ongoing to remind those in regions like Western Tennessee, part of the greater New Madrid Seismic Zone, that earthquakes pose a real danger. Credible experts believe that catastrophic loss of life and property in Memphis would most certainly be compounded by global business interruption when the ground there rumbles once again.
I’ve written in this blog before about Memphis, and in our commentary series as well. Thirty percent of all U.S. goods flow through there each year. It is the location of the world’s second busiest cargo airport, and center of the FedEx Express global headquarters. Imagine the worldwide commerce disruption when the movement of packages and shipments stops, even for a day.
So as you can see, we’ve made real progress on earthquake safety and resilience during the past five years, but we have much more to do.
Together, we drew more than 350 global experts on the scientific and practical challenges wrought by earthquakes, tsunamis, and catastrophic risk in general. And the response from the gathered academics, analysts, businesses, communicators, elected officials, emergency managers, engineers, experts, insurers, journalists, modelers, product manufacturers, psychologists, responders, scientists, and volunteers was tremendous. These individuals participated because they share our dread of what will happen when the next “big one” hits.
You can feel the sense of urgency in this brief video.
The NEC drew an impressive array of journalists and news organizations as well, including the BBC, Los Angeles Times, Time Magazine and many more. As they took their seats, our first keynote speaker, Dr. Tom Jordan of USC Southern California Earthquake Center (global headquarters of the Great ShakeOut earthquake drill) answered the question, What’s New? with a presentation of new science showing how the South San Andreas fault is “locked, loaded, and ready to roll.”
He explained through vivid maps and visuals how we are not just due, but overdue, for a major earthquake there.
We anticipated news media interest in the conference, and Dr. Jordan’s presentation ensured it. After award-winning Los Angeles Times Reporter Ron Lin posted this riveting article about Dr. Jordan’s briefing, an explosion of national and international news headlines followed. “Locked, loaded, and ready to roll” dominated the national news dialogue for days and weeks to come.
Mr. Lin’s article sharpened audience attention (in-person and virtual) as the rest of us went on to highlight best practices and challenges in building codes, communication, emergency management, outreach, policy, product innovation, research, and science.
Ten days later, the Los Angeles Times reported that Governor Jerry Brown planned to infuse the EEW system with $10 million in state dollars. This was a departure from the California governor’s previous position. Next, Congressman Adam Schiff voiced his intention to rekindle his effort to get Oregon and Washington state leaders to support the EEW system.
Lastly, but perhaps most importantly, congressional leaders signaled active support for National Earthquake Hazard Reduction Program (NEHRP) reauthorization. This is critical as NEHRP is the foundation for essential research that can advance breakthroughs like EEW systems, as well as seismic safety and resilience overall.
The 2016 NEC generated productive policy momentum that complements decades of work by the earthquake community, and experts like Dr. Lucy Jones. Today, as we recall the earthquake that emanated from rural Virginia five years ago, we must accept that earthquakes could happen nearly anywhere and, we must be ready when they do.

This month marks the 8th anniversary of StormStruck: A Tale of Two Homes® at Epcot® at the Walt Disney World Resort. FLASH’s groundbreaking experiment in social change communication represents the first time entertainment and story-telling were fully employed to inform and inspire the public to take action to be better prepared for extreme weather. At the time it was considered a big step and, for many, a slightly crazy idea.
Today, more than 5.5 million people have visited StormStruck since it opened. That number alone is a testament to its importance in the evolution of the weather mitigation movement. For those of us who had the privilege to be part of the project, the real measure of success was reported in a recent study conducted by behavioral science researchers from Carnegie Mellon University.
“This study included a pre-and post-exhibit survey and a 12-month follow-up survey with attendees at the Disney experience, StormStruck: A Tale of Two Homes. The purpose of the study was to measure individuals’ change in knowledge, perceptions of risk, feelings of preparedness, ability to name concrete precautionary actions, and subsequent behavior as a result of going through the StormStruck experience.”
The study found that a majority of the participants “gained critical action knowledge” and “retained that knowledge for 12 months.” Critically, “over 50% took some weather mitigation action.” The results were so impressive that one of the researchers commented that “we just don’t see this kind of numbers in social change communication.”
Not surprising to those of us who worked on the project, the study concluded that empowerment was a motivational key prompting participants to take preparatory action against severe natural events. “Specifically, our data show that greater feelings of empowerment after visiting StormStrucklead to stronger participant intentions to pursue critical preparatory action upon return home.”
Since helping bring StormStruck to life, I have worked with a number of organizations to help them envision new ways to use the latest communication technologies to create powerful behavior change messages. From these experiences I have compiled a short list of strategies for what comes next.
Social messaging will become increasingly experiential. In the future, a fully immersive social change experience like StormStruck will be the expected, not the exception.
This will be driven in part by the coming explosion in virtual and augmented reality technologies. The number of consumers experiencing virtual reality will grow from just over two million worldwide today to 24 million by 2018. Augmented reality, thinkPokémon GO, will grow even faster, reaching a billion users worldwide in the next four years.
Storytelling of all sorts will become increasingly mobile. Users will expect access anywhere, anytime, and for any amount of time – from a 30-second video break on Facebook (ok, I know those still turn into hours lost) to a weekend spent binge watching the latest Netflix release, consumption habits will become personalized. The era of the PSA will effectively be over.
Authenticity will replace authority. We are seeing an increasing shift from top-down change communication to bottom up – driven by interested individuals and “amateurs.” Just take a few minutes to browse the 300 plus hours of new videos uploaded to YouTube every second and you realize that not all of them feature funny cats or performances by amazingly talented 2-year olds. Individuals are coming together to co-create change messages on topics they care about personally. These “handcrafted” messages are increasingly being favored by audiences over the standard “expert” communications.
One thing that will remain the same with all these new technologies; social change communication will be effective only when we give audiences/participants the tools to make themselves the heroes of their own stories. No matter what technology you use or how you engage your audience to help create your future social change messages, the key findings of that Carnegie Mellon study will remain true. “Greater feelings of empowerment” will lead to actual changes in behavior. Ultimately, that will be the longest lasting impact of that crazy idea FLASH introduced to the world eight years ago.
As you might imagine, the first question we often get when we encounter new contacts in our movement is, “What exactly is the Federal Alliance for Safe Homes or FLASH Partnership, and how does it work?” Because achieving disaster resilience requires integration of many different areas of expertise, our partners include academics, architects, builders, code experts, corporations, emergency managers, engineers, first responders, floodplain managers, insurers, leaders, manufacturers, meteorologists, modelers, researchers, scientists, and many more.
We are a diverse coalition with the conviction that good science should lead to good building practices, and, ultimately, safe families and strong communities that can both resist and bounce back from natural disasters. With this “road to resilience” in mind, we lead—through collaboration, communication, and innovation.
I recently sat down with Dr. Marshall Shepherd, host of The Weather Channel’s clever Sunday show, WX Geeks to talk about the FLASH Partnership and highlight our new national hurricane resilience initiative, #HurricaneStrong. Thanks to his expert interview skills, a great producing team, and a national news channel that lives its commitment to disaster resilience, we had a stellar opportunity to tell our story.
The Florida Building Codes enacted, enhanced, and consistently updated since the devastating building failures of Hurricane Andrew in 1992 are considered a national standard for excellence in high-wind construction.
So, when our advocacy partners sent up an “all hands alert” just two weeks before the close of the Florida Legislative session, we were shocked to learn that the Florida Building Code was under assault. Someone, apparently a Florida Home Builders Association representative, had convinced a few legislators that it would be good idea to extend the update cycle for the entire state’s code from a three-year to a six-year cycle.
They attempted this by adding an amendment added to Committee Substitute #2 on House Bill 535, stating:
553.73 Florida Building Code.—
(7)(a) The commission, by rule adopted pursuant to ss.120.536 (1) and 120.54, shall update the Florida Building Code every 63 years.
This was done quietly as the bill headed to its last committee, and then off to the House floor. Senate Bill 704 was set to follow the same route. It’s important to note that often when legislation is made quietly and at the last minute, it’s because the action cannot hold up under public scrutiny. Or, as we like to say in Florida, it can’t survive the sunshine.
The three-year cycle is used by Florida, and most states, because it follows the International Code Council development process of new model codes crafted through consensus on a three-year, recurring cycle. Even so, there is often an administrative tail on the final adoption. Regardless, when we adopt and enforce the newest building codes, our building practices stay current with new products, science innovation, and post-disaster insights.
Yet some states and jurisdictions, like Minnesota and North Carolina, have elongated code adoption from three to six, or even nine years. These extended code cycles not only leave citizens without the benefit of current model building codes, but also impede the disaster safety movement goal to rapidly incorporate beneficial, post-disaster findings into model codes.
Opponents of timely adoption have convinced some lawmakers that there is no harm in switching from a three-year to a longer, six-year update cycle. They argue that it provides a cost savings with no offsetting harm to the overall construction in those states.
But they could not be more wrong. Here is how we made our case to the Florida press:
Stalling the timely adoption of the newest building code represents a backward step for construction, design, innovation, and disaster resilience overall with negative impacts across many fronts.
1. Families will be denied the latest insights and advances in construction technology and the benefits of innovation and advances that deliver savings across energy, fire and other cost drivers (ordinary water losses and/or catastrophic losses). For example, this will put essential code enhancements for flood resistance on hold.
2. The excellent building code policy record in Florida is one of the most important supports for the often-stressed property insurance system. This type of policy setback could have devastating effects on the delicate balance that has been so hard won post-Andrew.
3. The El Niño year has already delivered the projected tornadic and high wind events. The expected La Niña could bring similarly heightened activity. Further, many credible meteorology professionals suggest strong potential for a hurricane season reminiscent of the 2004-2005 activity level.
Shortly after the news spread of these amendments altering the Florida building code cycle from three to six years, the effort was abandoned. And, we are very relieved that it failed. But we should all be wary. If any Florida Legislator can be convinced that we don’t need to maintain current building codes in the most high-risk hurricane state, then we are not only forgetting history, but we are dooming ourselves to repeat it.
With this in mind, we’ve launched a new initiative,#HurricaneStrong, to help remind the public, leaders, and families alike, that we must remain vigilant to remain disaster resilient. I hope you’ll join us.
Many of us in the disaster-resilience movement have witnessed and participated in the creation of resilience measurement systems. Along the way, we’ve observed that one of the strongest aspects of our movement is also what makes measurement so difficult: diversity. There are so many puzzle pieces that must be considered—economic, physical, political, and social—just to name a few.
So over the next couple of posts, I plan to return to an examination of these issues because Big Data and the IoT can transform the disaster-resilience movement, and the implications are almost unfathomable. These concepts and their intersection present opportunities that we must understand and plan for before we can harvest any benefits, or at least prevent unintended consequences.
The first step is to develop uniform, consistent metrics to gauge progress toward resilient communities. We need verifiable, practical, and replicable tools. And we need to apply these tools to quality data.
At FLASH, we are concerned with community-wide resilience, but our work focuses more particularly on strengthening homes and safeguarding families from the ground up with strong building codes, beyond-code mitigation, and personal preparedness as part of a culture of resilience. These are foundational aspects of community resilience of course.
But here’s the challenge. Data on building characteristics and performance is not historically granular enough to derive ongoing insights except in certain post-disaster situations. Even then, we must obtain onsite analysis. That is why we need forensic engineering efforts like FEMA’s Mitigation Assessment Team post-disaster to assess structural performance, and evaluate failure patterns to inform to better building codes and standards in the future.
But this is where Big Data and the need for quality data (IoT) can make a difference. When IoT generated-data from new or emerging technologies like sensors can give us precise information on how a building performs, how will we leverage the information for better building practices to avoid future losses? Can we use the Big Data generated by the IoT to get ahead of the next disaster instead of learning after the fact? And what are the accepted metrics (if any) to build a credible database for our insights?
One way to understand the potential of Big Data and IoT is to apply the question to modern water detection systems. The marketplace is exploding with products like Fibaro Flood Sensor, Quirky Overflow, Utilitech Leak Detector, Wally, WaterCop, and more. These systems use sensors to detect moisture, temperature, and humidity and can identify water leakage from all kinds of sources like dishwashers, frozen pipes, washing machine hoses, and water heaters. This triggers an alert to the resident who can stop the leak, clean up the water, and prevent or mitigate costly damage and repairs.
This is a very meaningful breakthrough in loss prevention given the billions paid annually in water-involved insurance losses.
But in our vision of Big Data and IoT, we’d take it several steps further. Leak occurrences would be analyzed in the context of type of appliance, type of pipes, weather conditions, age of home, installation methods, etc. And any relevant specifics would be captured to develop insights on better (or worse) performing construction methods, products, and technologies. This data would inform to future products and practices.
From there, a database of homes with certain characteristics would be built. And this same approach using sensors and tech could be applied to many other failure modes from wind to seismic. All of these databases then would become elements of resilience measurement. Indeed, some already are.
The water detection example shows how resilience metrics are a Big Data problem. The myriad water detection devices cited above create data, but how to sort, harvest, and use the data effectively has a long way to go if it will be valuable beyond the individual loss. This type of micro-measurement is just one of the many ways we grapple with resilience measurement.
In our paper, we also examine various macro-resilience metrics/frameworks/indices including the U.S. Resiliency Council’s effort to rank buildings for seismic performance.
The key is working out how the micro-metrics and data can be developed and reliably applied in the macro-context of community resilience. There are existing options. For residential structures, MLS could include scores on the structural integrity, and attendant durability and life expectancy of a home and/or its location relative to natural hazards. Trulia and Zillow can make this information transparent to homeowners, and it would finally be a factor in driving the market value. Think about it. How is it that the most important aspect of a home—its structural integrity—is still not transparent to homeowners?
Cisco projects that by the year 2020 there will be 37 billion smart products on the market. Juniper Research predicts that there will be 10 million smart connected devices by 2017. It’s time for us to figure out a formula to harness the explosion of data that is headed our way.
This is an important conversation that is only beginning. Our next blog will look at the larger issue of Big Data and disaster resilience and how these movements are converging. And, you may want to join us as we spotlight this issue during our 2016 Annual Conference Meeting with a panel entitled The Next Generation of Resilient Communities. We are bringing together leading voices from government, private, and association to share their perspectives on current initiatives, opportunities, and challenges of fostering resilient communities.
Either way, we look forward to the ongoing conversation.
