After Hurricanes Katrina and Rita devastated Louisiana and brought billions of dollars of damage to the state, lawmakers worked with researchers, engineers and others to create and implement new codes and laws in an attempt to prevent such serious damage happening again. On Aug. 29, LSU and the LSU AgCenter hosted an event at the Energy, Coast and Environment Building in honor of the 20th anniversary of Hurricane Katrina, which made landfall in Louisiana on the same date in 2005. The daylong conference featured leading voices from LSU and government officials, who spoke about the impacts that hurricanes Katrina and Rita had on Louisiana and how policies and research have changed since those storms. As a part of the program, Carol Friedland, the director of the AgCenter LaHouse Research and Education Center, spoke alongside Brad Hassert, executive director of the Louisiana State Licensing Board for Contractors, for a seminar called “Innovating Resilience: Solutions Inspired by Katrina.” The two discussed recent developments in building materials and building codes that showed the changes, or lack thereof, since the two devastating hurricanes. At the time of the storms, building codes were not uniform in the state, and some parishes had almost no building codes at all. After Katrina and Rita, however, officials pushed for a unified code that better protected Louisiana residents from dangerous storms and weather events. “After Hurricane Katrina, we actually enacted very strong legislation to adopt the model code,” Friedland said. “Also, at the same time, the FEMA mitigation assessment team went out and documented a lot of the failures from Katrina. This program really helps us learn around the country what are the practices that are working and what are the practices that are not working and then getting those integrated into the code process.” Friedland went on to talk about some developments for houses that she has been working on, like “fortified roofs,” which are new roofs that will protect residents more efficiently than the codes required in Louisiana. Friedland also talked about the process of implementing new codes. Researchers must find agreement with governmental entities and other parties, like insurance adjusters and contractors, to succeed, she said. Hassert spoke about the importance for homeowners to find a licensed contractor after a weather event causes damage to their house. This is mostly to ensure that the house will be repaired to code and so the homeowners will not be scammed or stolen from. Hassert, who was recently appointed executive director of the Louisiana State Uniform Construction Code Council, urged researchers and other stakeholders to come together and participate in council meetings so they can make the most informed and beneficial decisions that they can. Both Hassert and Friedland believe there is work to do to improve the codes and building standards in Louisiana houses, but with communication and more involved research, enhancements can be made. “One of the ways I like to frame this is to think about are we happy with the level of losses that we have?” Friedland said. “Do we think that we’re doing well? Who is happy with the level of loss that we see? I think we can still do better.” Original article posted by the LSU AgCenter here. 

The American Society of Civil Engineers (ASCE) recently released its new standard for flood-resistant design and construction, ASCE/SEI 24-24, which provides new minimum requirements that can be adopted for all structures subject to building codes and floodplain management regulations. The new elevation standard was directly supported by LSU research and should help reduce flood risk and make flood insurance more affordable. “Without the research by the LSU AgCenter, the advancements made to the elevation requirements would not have been possible,” said Manny Perotin, co-chair of the Association of State Floodplain Managers’ Nonstructural Floodproofing Committee, who helped update the standard. “Dr. Carol Friedland’s research shows there are better ways to protect communities from flooding than adding one foot of additional freeboard.” The research team, led by Friedland, an engineer, professor, and director of LSU AgCenter’s LaHouse, showed how previous standards were failing to protect some homeowners. They mapped the impact of moving from a standard based on a fixed freeboard amount to being based on real risk in every census tract in the U.S. In response to these findings, they developed a free online tool to help builders, planners, managers, and engineers calculate the elevation required under the new standards. “Many on the committee said it would be too hard to do these complex calculations,” said Adam Reeder, principal at the engineering and construction firm CDMSmith, who helped lead the elevation working group for the new ASCE 24 elevation standards. “But the LSU AgCenter’s years of research in this area and the development of the tool makes calculations and implementation simple. This allowed the new elevation standard to get passed.” Flooding, the biggest risk to homes in Louisiana, continues to threaten investments and opportunities to build generational wealth. On top of flood losses, residents see insurance premiums increase without resources to help them make informed decisions and potentially lower costs. In response to this problem, Friedland is working on developing a whole suite of tools together with more than 130 partners as part of a statewide Disaster Resilience Initiative. When presenting to policy makers and various organizations, Friedland often starts by asking what percentage of buildings they want to flood in their community in the next 50 years. “Of course, we all want this number to be zero,” Friedland said. “But we have been building and designing so 40% will flood. People have a hard time believing this, but it’s the reality of how past standards did not adequately address flood risk.” Designing to the 100-year elevation means a building has a 0.99 chance of not flooding in any given year. But when you run that probability over a period of 50 years (0.99 x 0.99 x 0.99… 50 times, or 0.99 ^ 50), the number you end up with is a 60.5% chance of not flooding in 50 years. This means a 39.5% chance of flooding at least once. “We’ve been building to the 100-year elevation while wanting the protection of building to the 500-year elevation, which is a 10% chance of flooding in 50 years,” Friedland said. “Now, with the higher ASCE standard, we can finally get to 10% instead of 40%.” As the AgCenter’s research led to guidelines, then to this new standard, Friedland has also been providing testimony to the International Code Council to turn the stronger standard into code. In May, Friedland helped lead a workshop at the Association of State Floodplain Managers’ national conference, held in New Orleans. There, she educated floodplain managers about the new standard while demonstrating LSU’s web-based calculation tool, which was designed for professionals, while her team also develops personalized decision-making tools such as Flood Safe Home for residents. At the conference, Friedland received the 2025 John R. Sheaffer Award for Excellence in Floodproofing. More than two-thirds of the cost of natural hazards in Louisiana comes from flooding, according to LSU AgCenter research in partnership with the Governor’s Office of Homeland Security and Emergency Preparedness for the State Hazard Mitigation Plan. That cost was recently estimated to rise to $3.6 billion by 2050. “Historically, we have lived with almost a 40% chance of flooding over 50 years, which in most people’s opinion is too high—and the number could be even higher,” Reeder said. “Most building owners don’t understand the risk they are living with, and it only becomes apparent after a flood. The work done by the LSU AgCenter is critical in improving resilience in communities that can’t afford to be devastated by flooding.” “This may be the most significant upgrade in the nation’s flood loss reduction standards since the creation of the National Flood Insurance Program minimums in 1973, and it could not come at a better time as annual flood losses in the country now average more than $45 billion per year,” said Chad Berginnis, executive director of the Association of State Floodplain Managers. In addition to LaHouse’s work to prevent flooding, Friedland’s team is also working to increase energy efficiency in homes to help residents save money on utility bills. Their HEROES program, an acronym for home energy resilience outreach, education, and support, is funded by the U.S. Department of Agriculture and has already reached 140,000 people in Louisiana.

As temperatures warm up across Louisiana, so does termite activity. Homeowners may soon begin to notice large swarms of winged insects in and around their homes. These are termite alates, also known as swarming termites. “Swarming is how termites establish new colonies,” said LSU AgCenter entomologist Aaron Ashbrook. “Seeing swarms around your home doesn’t necessarily mean you have an infestation, but it does mean termites are nearby.” Alates are the reproductive members of a future termite colony if they can successfully establish. Each spring, usually following a warm rain, these termites leave their established colonies to find new places to nest. Many alates are produced because a low percentage of them are able to establish a colony. After swarming, they shed their wings and pair off to begin new colonies, which is how they end up in homes. Louisiana’s warm, humid climate makes it an ideal environment for termites, especially the Formosan subterranean termite, one of the most destructive species in the United States. Termites can silently cause thousands of dollars in damage before homeowners know they’re there. Tips for homeowners: Don’t panic, but don’t ignore it. Seeing swarms outside is common, but if they're inside your home, call a licensed pest control professional. Look for signs. Discarded wings, mud tubes, water stains, moisture buildup, and soft or hollow-sounding wood can all indicate a problem. Reduce moisture. Termites thrive in damp environments and require moist wood to attack structures. Fix leaks and ensure proper drainage around your home. Schedule regular inspections. Annual termite inspections are recommended, especially in high-risk areas like Louisiana. “Termites can cause extensive structural damage to your home that may go unnoticed,” said Carol Friedland, director of LaHouse Research and Education Center. “Early detection and prevention can save homeowners a lot of stress and money.” The LSU AgCenter’s Department of Entomology and LaHouse Research and Education Center provide research-based guidance to help Louisiana residents protect their homes from termites and other structural pests.
