Inland neighborhoods were ravaged by wind gusts upward of 140 miles per hour, causing any sedentary object \u2014 from coconuts to truck beds \u2014 to become lethal projectiles, followed by nearly two weeks without power (more than 250,000 residents in Cape Coral alone).<\/p>\n<p>The community surrounding Mullock Creek in south Lee County \u2014 a low-lying coastal preserve vital to the watershed for surrounding areas such as Estero and San Carlos Park \u2014 experienced similar impacts.<\/p>\n<p>According to the <a href=\"https:\/\/www.nhc.noaa.gov\/data\/tcr\/AL092022_Ian.pdf\" class=\"Link\" target=\"_blank\" rel=\"nofollow noopener\">National Hurricane Center tropical cyclone report for Hurricane Ian<\/a>, Mullock Creek Preserve and surrounding areas were submerged in more than 8 feet of water.<\/p>\n<p>To address this, the <a href=\"https:\/\/www.fema.gov\/\" class=\"Link\" target=\"_blank\" rel=\"nofollow noopener\">Federal Emergency Management Agency<\/a> (FEMA) <a href=\"https:\/\/www.leegov.com\/dcd\/flood\/floodways\/femamapchanges2026\" class=\"Link\" target=\"_blank\" rel=\"nofollow noopener\">updated the emergency flood maps<\/a> for residents and property owners surrounding the preserve, nearly four years after Ian\u2019s landfall. The alterations are slated to take effect this summer.<\/p>\n<p>But there\u2019s a common misconception regarding these maps and why they are altered \u2014 one Donald Duke, Ph.D., a Florida Gulf Coast University professor in the Department of Ecology and Environmental Studies, said property owners in all areas need to remain privy to.<\/p>\n<p>\u201cIt\u2019s a mistake to think of these maps as identifying this area is prone to flooding, in that area it\u2019s safe from flooding,\u201d Duke said. \u201cThat\u2019s just not so.\u201d<\/p>\n<p>Instead, Duke said the maps are drawn &#8220;probabilistically&#8221; and that, year-after-year, nearly half of the flood insurance claims are filed outside designated flood zones.<\/p>\n<p>\u201cIt\u2019s the best estimate based on the information we have from the past about flows and about changes that we\u2019ve seen in watershed,\u201d Duke said.<\/p>\n<p>Duke said the process is largely driven by FEMA\u2019s program, which funds states. States then pass those funds to municipalities. He also said that the voluntary <a href=\"https:\/\/www.floridadisaster.org\/dem\/mitigation\/floodplain\/crs\/\" class=\"Link\" target=\"_blank\" rel=\"nofollow noopener\">Community Rating System<\/a> (CRS) helps track actions taken by communities to mitigate flood risk. <\/p>\n<p>By undertaking these activities, communities are awarded points. Based on the number of points a community earns, it is placed in one of 10 CRS classes. Each class determines how much of an insurance premium discount a community receives, ranging from 5% to 45%.<\/p>\n<p>Duke also said the maps are a way for the insurance industry to base rates for certain areas, determine which properties are required to carry flood insurance, and set building codes.<\/p>\n<p>\u201cIt\u2019s more [of a] likelihood that some flood will happen, then you pay more for it, just as a driver who has demonstrated that they have more accidents than someone else will pay more for auto insurance,\u201d Duke said.<\/p>\n<p>As development persists, flood map revisions have increased in frequency as well. <a href=\"https:\/\/www.leegov.com\/dcd\/flood\/floodways\" class=\"Link\" target=\"_blank\" rel=\"nofollow noopener\">Lee County\u2019s first flood map<\/a> took effect in 1984, followed by a more than 20-year-gap with revised versions taking effect in 2008, 2018, 2022, and now 2026.<\/p>\n<p>Duke said the main causes for these changes are an increase in development \u2014 especially projects that require concrete, altering waterflow \u2014 and increasingly erratic climate conditions.<\/p>\n<p>\u201cA map that was drawn in 1970 with the pace of change that we\u2019ve seen in land use in Florida is very badly outdated,\u201d Duke said.<\/p>\n<p>If your flood zone changed because of the revisions and you are concerned about the upcoming hurricane season, Billie Jacoby, Lee County\u2019s floodplain manager and CRS coordinator, said there are proactive measures property owners can take to alleviate flood risk and limit damage and rising costs after the storm. The most important is to obtain flood insurance if you haven\u2019t already.<\/p>\n<p>\u201cWith so many damaging storms over the past several years, we have learned the importance and need for not only flood insurance but also the need to better understand the <a href=\"https:\/\/www.fema.gov\/floodplain-management\/financial-help\/increased-cost-compliance\" class=\"Link\" target=\"_blank\" rel=\"nofollow noopener\">Increased Cost of Compliance<\/a> (ICC) portion of the policy,\u201d Jacoby said.<\/p>\n<p>Jacoby also said not to wait to purchase flood insurance, as in most cases, there is a 30-day waiting period.<\/p>\n<p>For more information, visit your municipality\u2019s website.<\/p>\n<p>WGCU is your trusted source for news and information in Southwest Florida.
