Floods were considered a blessing by certain civilizations—the Egyptians relied on the Nile’s yearly overflow for fertile soil—but they also stand as some of history’s most devastating natural disasters. Whether due to heavy rains, storm surges or busted dams, deluges have often claimed thousands of lives and left whole cities in ruin. In some cases, they even permanently changed the planet’s geography.
1. The Johnstown Flood was so massive it equaled the flow of the Mississippi River.
The disaster began shortly after 3 p.m on May 31, 1889, when a dam on Pennsylvania’s Lake Conemaugh washed away following several days of drenching rain. The collapse unleashed some 16 million tons of water, which quickly turned into a 40-foot-high, half-mile-wide surge of mud and debris. An hour later, the wave struck Johnstown like a giant fist, crushing some 1,600 buildings and sweeping away everything in its path. When the waters finally receded, over 2,200 people were dead and many more were injured or homeless. The flood was later blamed on the poorly maintained dam, which was owned by a hunting and fishing club, but no one was ever held financially liable for the disaster.
2. The Central China Flood may have killed as many as 3.7 million people.
In the summer of 1931, heavy snowmelt, torrential rains and seven different cyclonic storms combined to produce the most devastating flood in Chinese history. In the month of July alone, central China was swamped by as much precipitation as it typically received in a year-and-a-half. By August, the Yangtze, Yellow and Huai Rivers had all burst through their badly managed dikes and flooded an area larger than the size of England. Thousands died from drowning during the initial phase of the flood, but even more followed due to widespread famine and outbreaks of diseases such as cholera, typhoid fever and dysentery.
3. One flood was known as the “Great Drowning of Men.”
The Grote Mandrenke was the result of a vicious North Sea tempest that swept across parts of Europe in January 1362. The effects of the storm were first felt in England, where one chronicler wrote that “a strong gale blew from the north so violently for a day and night that it flattened trees, mills, houses and a great many church towers.” The damage was even worse in the Netherlands, Germany and Denmark, which experienced a catastrophic storm surge that overran nearly every dike and levee in its path. Anywhere from 25,000 to 100,000 people drowned, and it was said that 60 different parishes in Denmark were “swallowed by the salt sea.” Elsewhere in the Low Countries, erosion from the flood permanently transformed the coastline and led to the disappearance of whole islands. Along with other storms during the Middle Ages, the Grote Mandrenke also played a role in forming a shallow North Sea bay in the Netherlands known as the Zuiderzee.
4. Few floods in recorded history compare to the one that rocked the Indus River Valley in 1841.
The trouble began in January of that year, when an earthquake triggered a massive landslide on the slopes Nanga Parbat, a Himalayan peak located in what is now Pakistan. So much bedrock tumbled off the mountain that it blocked the flow of the rushing Indus River and created a lake 500 feet deep and several dozen miles long. When the natural dam finally burst that June, the lake emptied at a rate of 540,000 cubic meters per second, unleashing a gargantuan flood wave almost 100 feet high. The casualties from the disaster were not recorded, but it was known to have wreaked havoc on several hundred miles of the Indus Valley. Whole villages were wiped off the map, and an entire 500-man Sikh army was reportedly consumed near the city of Attock.
5. The United States’ most iconic river was the source of its most destructive freshwater flood.
In the spring of 1927, following months of unrelenting rain, the lower Mississippi River swelled to its breaking point and overran its levee system. The resulting flood swamped some 16 million acres across seven states from Cairo, Illinois, to New Orleans. The damage was at its worst in Arkansas, Mississippi and Louisiana, where the river inundated so much land it temporarily created a shallow sea over 75 miles wide and forced thousands to be evacuated by boat. By the time the waters finally receded later that summer, at least 250 people were dead and another 1 million had been driven from their homes—roughly one percent of the entire American population at the time.
6. This 1966 flood struck a devastating blow to Italy’s cultural treasures.
The deluge began on November 4, when a period of steady rain caused the Arno River to overflow, sending 18 billion gallons of mud and sludge pouring through the streets of Florence. Thousands of homes and businesses were destroyed, but the water also reached several art galleries and libraries containing priceless Renaissance-era relics. Some 1.5 million books were left submerged in the Biblioteca Nazionale. Elsewhere in the city, the torrent destroyed or damaged 1,500 frescoes, sculptures and paintings. In the wake of the disaster, a band of international volunteers known as the “Mud Angels” descended on Florence to pick through the debris and salvage waterlogged canvases and manuscripts. The teams rescued countless artworks, but in many cases, the restoration process has taken decades. Work on one famous painting, Giorgio Vasari’s 1546 “Last Supper,” was only completed in 2016.
7. Not all of history’s great floods can be blamed on Mother Nature.
During the Second Sino-Japanese War in June 1938, Chinese Nationalist troops intentionally destroyed several dikes on the Yellow River in an attempt to thwart invading Japanese forces. The Chinese hoped the scorched earth tactic would block Japanese access to a railway and slow their westward progress. What happened instead was an environmental disaster. Once the muddy river was set loose, it tumbled off course and flooded a 21,000-square-mile swath of Henan, Anhui and Jiangsu provinces in the center of the country. An estimated 4 million people were displaced from their homes, and 800,000 died from drowning, disease and famine after the deluge continued unchecked. “Residents who have not died in the floods perish from hardship,” read a 1940 Chinese government report. “Those who have fortunately stayed alive are already urgently gasping for breath and groaning in agony.” The disaster dragged on for the rest of the war—the Chinese government initially tried to blame the busted dikes on a Japanese bombing—and it wasn’t until 1947 that engineers and laborers succeeded in returning the Yellow River to its original course.
8. Historians are still not entirely sure what caused one of Britain’s worst natural disasters.
The deluge began on the morning of January 30, 1607, when a great surge of seawater overran some 200 square miles of southwest England and Wales, completely drowning at least 20 villages. One witness wrote of seeing “huge and mighty hills of water, tumbling one over another” and advancing with “great swiftness” over the landscape. Such descriptions have led some researchers to theorize that the floods were the result of a massive tsunami brought on by an earthquake, but others maintain that a squall-induced storm surge and spring tide are the more likely culprits. Whatever its cause, the flooding proved devastating for the low-lying regions surrounding the Bristol Channel, where some 2,000 people were killed. In Somerset, the floodwaters surged 15 miles inland and briefly turned the famed hill at Glastonbury Tor into an island.
10 Most Catastrophic Natural Disasters In History
It is seen that over the years there have been a lot of natural disasters occurring in the world that has stolen many lives and has lead destructions and upheaval for the people.
There are many criteria which prove that the natural disasters have a horrifying sight and has increased death toll rates as well as resulted in millions of destruction of both life and property on the Earth. These devastating panic-stricken natural disasters are recorded in the history of the world.
Some of these natural disasters include volcanic eruptions, floods, earthquakes, Heat waves, drought, cyclone, tsunami, typhoon and many others. The impact of these disaster’s impacts depends on the size and the location where it occurred. If the prone area has a large amount of population than the destruction to the life and property increases.
There have been several such kinds of disasters which proved to be devastating for the country and has done a lot of damage to the economic conditions of the country. Technology has been upgraded to predict the occurrences of these events beforehand. With the help of which people can be evacuated from the region and we can minimize the damage it can create in the area and the surroundings.
Let’s take a look at the most panic-stricken disasters occurred in the history:
1) China Floods
The China flood also is known as the yellow river flood occurred in the year 1931. This flood is considered to be one of the worst disasters in the world. The flood is considered among the first among the deadliest disasters.
Approximately the death toll rate of the Republic China. Estimates of China stated that it near about 1,4,500 thousands of people were killed and about damaged about 28.5 million worth of money.
The Yangtze and Huai river floods reached the capital of China. The city located on the island suffered a huge catastrophic damage. Millions of people died because of drowning in the flow whereas some died of the starvation and water-borne diseases.
2) Earthquake And Tsunami In Indian Ocean
The Tsunami had hit several countries of South and South Asia in 2004. The Tsunami and its after effects were responsible for the destruction and loss on the Indian Ocean. This disaster occurred due to the disturbance in the tectonic plates which resulted in the Earthquake in the Indian Ocean due to which large waves swept away the southern states of India.
It was the third largest Earthquake recorded in the history on 26th November 2004 with a magnitude of 9.1 on the Richter Scale and struck the coast of the Indonesian island of Sumatra. It killed 2,20000 people of the various countries which include Indonesia, India, Sri Lanka, Thailand, and Maldives. Thus the resulted tsunami is known as Indonesian Tsunami, Indian Ocean tsunami and much more.
3) Bhola Cyclone
It was one of the most devastating tropical cyclones in the world that struck East Pakistan and the India’s West Bengal. About 5,00,000 people lost their home in the storm. Statistics show that it was the sixth largest storm recorded in the Ocean and was the strongest amongst them. Thus it is considered under the deadliest cyclone disaster. The cyclone was originated in the Bay of Bengal and it moved forward with intense speed towards the North.
It killed around 3,00,000 people in the East Pakistan known as Bangladesh. It devastated offshore islands, destroyed crops wiped out villages in the most throughout the region. The most adverse effect was seen in the Upazila and Tazumuddin in which about 45% of the population were killed.
4) East Africa Drought
The drought-affected the East Africa in between 2011 and mid of 2012. According to the experts, it was one of the most destructive in the past 60 years. The drought threatened the life of 9.5 million people of Ethiopia, Kenya, Djibouti threatening the people of Africa. This drought-affected the children making them malnutrition which led the life of the people. The food crises in the Somalia affected the farmers.
This drought resulted in the death of people as well as it also created the deadly famine in the country. This natural disaster is one of the catastrophic in the history.
5) Typhoon Tip
Typhoon Tip also knew as Typhoon Warling was one of the greatest and was one of the most intense tropical cyclone ever recorded in the history. Pacific cyclones are the most powerful one in comparison with the Atlantic hurricane in terms of the strength. The tip was developed as a result of the disturbance in the monsoon.
It was recorded on the 12th October 1979 in the history when the tip was originated in the ocean with lowest air pressure. It killed around 99 people which are a less amount than some of the disasters we have included in the list but denying the fact that this must be taken as the warning that more intensified Typhoon can strike.
6) Haiyuan Earthquake
This disaster occurred on the 16th December 1920 in Ningxia in the Republic of the China. It was reported to have 7.7 magnitude earthquake on the Richter scale. Over around 73,000 people were killed in the Haiyuan County. According to the United State Geological Survey, this disaster took away the life of about 2,00,000 casualties in Haiyuan.
Destruction was stretched to the seven provinces of the china which includes Taiyuan, Xiang, Xining, and Yinchuan. Nearly all the houses were found collapsed in the two cities of Longde and hunting and more than 30,000 people were will be killed in Guazan county.
7) Nevado del Ruiz Volcano Eruption
This disaster is also known as the La Mesa de Herveo, it is a volcano which is present at the Caldas and Tolima in Columbia. This stratovolcano is responsible for creating the world’s second largest volcano.
This volcano erupts Plinian soft currents of gases and the molten lava which is known as Pyroclastic flows. Buried and destroyed the whole town of Tolima on 13th November 1985. It killed around 25,000 people in the disaster which are popularly known as Armero Tragedy.
8) Chile Earthquake
It is the greatest Chilean Earthquake in the history. It was recorded that the earthquake was intense and it had a magnitude of 9.2 to 9.4 on the Richter scale and is thus one of the worst disasters in the history of Chile and in the world.
It occurred in the afternoon and lasted for approximately 10 minutes. The tsunami caused due to this earthquake affected Philippians, new Zealand, Japan, Hawaii, and Australia. To tell about the number of deaths and the monetary loss is not possible as it was uncertain. According to some publishers, 1,000 to 6,000 people were killed but the exact death rate is not mentioned anywhere.
9) Yangtze river flood
When torrential rains hit southern China in 1931.This caused the river to flood. As a result of this is 3.7 million people dead. It is thus considered to be one of the worst disasters of the 20th century.
Yangtze river is one of the largest river of Asia and thus any disturbances in the river can affect a large group of the people.The consequences of the river were terrible due to heavy rains and this resulted in the death of a lot of people of China.
10) European heat wave
Europe has never seen scorching hot summers. In spite, it is a place which remains cold throughout the year. But in 2003 they were hit by the heat waves which made the United States and Australia sit back it resulted in the health crises in the several countries. The effect of the disaster was severe in the Ukraine, as it suffered from the crop loss about 75% field was affected.
The extreme temperature caused the whole country to be dried up most of the Europe. This caused the forest fires and even flooding. There were 14,802 people were killed in France

Impact of Floods
Natural hazards are all capable of causing severely negative consequences. Of all such occurrences, however, floods happen to be the ones that lead to the greatest number of deaths. According to a World Disasters Report, 44 percent of the deaths caused by natural hazards in 2013 could be attributed to floods. The financial cost of these natural disasters isn’t to be scoffed at either. Third world countries and developing economies happen to be more vulnerable to begin with, since a bigger number of buildings is concentrated in vulnerable regions. Sadly, many of the most damaging flooding events have taken place in such places. Climate change is also having an impact on the statistics and, unfortunately, experts predict that the flooding situation is going to become worse in years to come unless countermeasures are introduced to turn back the tide on climatic changes resulting from human activities.
Banqiao Dam Burst (1975)
The construction of Banqiao dam started in the year 1951, to meet the growing demands of electricity and also to check downstream flooding during peak seasons.
The design of the dam was regarded as not standard since the Chinese authorities were short of concrete hydrology data and the dam was opened in the year 1952.
An unexpected natural disaster in the form of Typhoon Nina struck Zhumadian region in the year 1975 (August), causing an enormous amount of rainfall in excess of 1000 mm per day.
Subsequently, Banqiao dam burst open and the Chinese authorities had put the estimated figures of lost lives to around 0.2 m.
Even today, people in China squarely blame the government for its failure to handle the situation in an effective manner.
Historical Flooding
The USGS provides practical, unbiased information about the Nation's rivers and streams that is crucial in mitigating hazards associated with floods. This site provides information about the USGS activities, data, and services provided during regional high-flow events, such as hurricanes or multi-state flooding events. The USGS response to these events is typically managed by the National Flood Hazard Coordinator.
Click on an event name to access news, data, and resources for regional flood events that involved a national coordinated USGS response.
Hurricane Dorian - Hurricane Dorian, a Category 5 hurricane, took nearly two weeks (August 24 - Sept 7, 2019) to pass from the Caribbean to Canada.
Hurricane Michael - Hurricane Michael made landfall near Panama City, Florida, on October 10, 2018, as a Category 5. It caused catastrophic flooding and wind damage across Central America and the Southeastern U.S., particularly the Florida panhandle.
Hurricane Florence - Hurricane Florence's rains caused severe freshwater flooding as it stalled over North and South Carolina in September 2018.
Hurricane Nate - Capping off an intense 2017 hurricane season, Nate made landfall on the Louisiana and Mississippi coasts on October 7.
Hurricane Maria - Maria made landfall in Puerto Rico as a strong category 4 hurricane, with winds of 155 mph that knocked out power for the entire island.
Hurricane Jose - Even though Hurricane Jose never made a direct impact on the United States in September 2017, it generated large waves along its entire path and coastal effects have been felt from Florida to New England.
Hurricane Irma - Hurricane Irma was the first major hurricane to hit Florida since Hurricane Wilma struck in 2005.
Hurricane Harvey - On August 25, 2017 Category 4 storm Hurricane Harvey struck Texas, causing an estimated $125 billion in damage.
Pacific Winter Floods - The 2017 flood season began with atmospheric rivers pouring rain over large areas of California, Nevada, and Oregon.
Midwest Spring Floods - Large portions of Missouri, Illinois, Indiana, Ohio, Oklahoma, and Arkansas experienced widespread springtime flooding.
2015/2016 Winter Floods - Widespread flooding from severe December 2015 rainfall affected large sections of the central and southern United States. Stress on the Nation's major rivers continued into 2016, as portions of the Ohio River, Missouri River, and Mississippi River threatened to match or exceed 2011 levels.
January Noreaster - A strong winter storm brings record-setting storm surge to the mid-Atlantic.
Southern Spring Floods - Spring rains cause flooding across areas of Texas, Louisiana Arkansas, and Mississippi.
August Louisiana Floods - Rainfall across Louisiana including amounts above 30 inches in some locations resulted in record-setting flooding.
September Northern Plains Floods - More than 12 inches of rain fell in northeast Iowa, southeast Minnesota, and southwest Wisconsin during a 24-hour period on September 22 and 23, 2016. Wisconsin streamgages saw floods in the 10- to 100-year range.
Hurricane Matthew - A severe hurricane crossed Cuba and the Bahamas on its way toward the Florida coast.
Summer Central Floods - Repeated high-intensity storms wiped out drought conditions across much of Texas while Oklahoma experienced the single largest month of rainfall ever recorded. Soon after, farm-belt States and the Ohio River valley endured an unusually wet summer.
Autumn Appalachian Floods and Hurricane Joaquin - While Hurricane Joaquin threatened from the South Atlantic Ocean, weeks of persistent and sometimes heavy rain soaked the Appalachian States. USGS crews prepared for the double-threat of inland flooding and potential coastal flooding and damage from the Hurricane. Joaquin eventually passed by with moderate effects on the coast while USGS crews remained occupied with the inland floods.
2015/2016 Winter Floods - Widespread flooding from severe December 2015 rainfall affected large sections of the central and southern United States. Stress on the Nation's major rivers continued into 2016, as portions of the Ohio River, Missouri River, and Mississippi River threatened to match or exceed 2011 levels.
April floods in Alabama and Florida - Heavy rains over Southern Alabama and the Florida panhandle brought peak-of-record flooding on Bayou Marcus Creek and over $21 million in damage to Escambia County infrastructure.
June floods in South Dakota, Minnesota, and Iowa - Peak-of-record flows in northern Minnesota's Rainy River Basin kept USGS crews busy while record floods further south in the Big Sioux River Basin left their mark in South Dakota, Minnesota and Iowa.
August-September Southwest flood events - Heavy August rains followed by remnants of Hurricane Odile in September brought major flooding to parts of Arizona.
December Pacific Coast flood events - Regional flooding, including flash floods, heavy snows in the mountains, high winds, and mudslides visited Oregon, Washington, and California. Although widespread rain provided much-needed water, it did not alleviate the long-term drought in California.
September Southwest Floods - Heavy mid-September rains brought major flooding to parts of Colorado, New Mexico, Arizona and Utah.
May-June Midwest Floods - Late May and early June brought additional flooding to Iowa, Missouri Illinois, Indiana, Oklahoma, and Arkansas.
April-May Midwest Floods - Heavy rainfall (locally as much at 8 inches in some locations) fell across parts of Missouri, Iowa, Illinois, Wisconsin, Michigan, and Indiana in mid-April, resulting in major flooding on several rivers. Late snow-melt in the northern midwest added to the flooding in late April and early May.
Hurricane Isaac - USGS scientists, engineers, and technicians worked along the Gulf coast in response to Hurricane Isaac, deploying and maintaining 188 storm tide sensors and real-time streamgages in anticipation of Isaac's arrival. The USGS, in concert with our partners, is providing scientific assessments of the challenges wrought by Isaac.
Hurricane Sandy - Following on the heels of Hurricane Isaac, Hurricane Sandy gave USGS scientists, engineers, and technicians another opportunity to deploy storm tide sensors and real-time streamgages, this time, in over 224 locations.
April 2011 Arkansas Flood - The summer of 2011 brought historic flooding to Arkansas. In addition to the massive floodwaters that coursed down the Mississippi River, unusually heavy rainfall caused backwater flooding and levee failure along the Black and White Rivers as well.
April 2011 North Dakota Flood - On April 6, 2011, warmer-than-expected temperatures, combined with some light rain, initiated the melt process. Soon, record-breaking floodwaters came coursing down the Missouri, Red, and Souris Rivers, leading to massive flooding and even forcing some North Dakotans to flee their homes.
May 2011 New Madrid Floodway - In response to dangerous flood levels near the confluence of the Ohio and Mississippi Rivers, the US Army Corps of Engineers (USACE) activated the Birds Point-New Madrid floodway (New Madrid Floodway in USGS literature) at 10:03 pm on May 2, 2011 by detonating explosives along a stretch of the Mississippi River levee just downstream of Cairo, Illinois.
May 2011 Louisiana flood - USGS crews from the Louisiana Water Science Center deployed stage sensors and rapid deployment real-time streamgages in the Morganza floodway in anticipation of the operation of the floodway, which was opened May 14, 2011 at 3:00pm. The USGS also made streamflow, water quality, and sediment concentration measurements in association with the Bonnet Carre' spillway upstream of New Orleans.
May 2011 Memphis, Tennessee flood - The USGS Tennessee Water-Science Center worked in cooperation with FEMA, USACE, National Weather Service, and local agencies to provide emergency real-time surface-water stage gages at critical locations in Shelby County.
Summer Missouri River Basin flood - USGS crews from Montana to Missouri watched closely as a higher-than-average snowmelt runoff combined with heavy spring rains advanced down the Missouri River system. Large reservoirs managed by the US Army Corps of Engineers (USACE) are carefully managed with the help of data from the USGS streamgaging network to control flood levels.
Hurricane Irene - The USGS deployed stage sensors and rapid deployment real-time streamgages along the East Coast in anticipation of Hurricane Irene. USGS measurements and geospatial products are valuable tools for providing scientific assessments to decision makers both during the event and for future planning after the event.
Tropical Storm Lee - USGS personnel respond to the second major storm in 2 months as Tropical Storm Lee adds 20 inches of rain to an already wet season.

Pictures Reveal Hurricane Harvey's Catastrophic Destruction
Rainfall from the storm is causing life-threatening floods.
Hurricane Harvey roared to shore on August 25 as a Category 4 storm, with 130-mph winds by the time it hit Rockport, Texas. Heavy rainfall has caused catastrophic flooding in Houston and along the Texas Gulf Coast, displacing thousands and causing dozens of deaths.
The gallery above features photography of the ongoing disaster and will be updated as the situation develops.
More than 2.3 million people live in rain-soaked Houston, and hundreds of thousands have been without power. (Learn the science behind what makes Harvey so deadly.)
Harvey is the strongest storm to hit a U.S. coast since Hurricane Wilma in 2005, and it has destroyed many buildings along the coast. Harvey was downgraded to a Category 1 hurricane by early Saturday morning before being designated a tropical storm, but the most catastrophic effects of the storm are unfolding over several days. Flooding is among the worst in U.S. history.
As much as two feet of water has fallen in some neighborhoods, and dams have spilled over their capacity, adding to the floods. A disaster declaration requested by Texas Govenor Greg Abbott was granted by President Trump, who visited the region. The proclamation allows federal funds to be used for local disaster relief.
Houston was once largely a swamp and relies on a decades-old system of canals to drain flooded streets. Those by creeks and bayous have faced high flash flood risks. An investigation last year by the Houston Chronicle found that many of these waterways were built before the city's population exploded and when rainfall estimates were lower. The estimated $26 billion it would take to update these channels doesn't seem likely to happen soon.
How the storm will affect the region's major oil and gas hub remains to be seen, although refineries have already been closed. Gas prices have already surged, but of particular concern are potential long-term impacts to the refineries that flank the Houston Shipping Channel, one of the busiest shipping lanes in the world.
Following Hurricane Ike in 2008, ProPublica and the Texas Tribune investigated how a major hurricane could affect this portion of the city, finding serious potential for environmental damage from oil and chemical leaks and major economic implications to disruptions to the industries.
Houston's Harris County Sheriff Ed Gonzales is continuing to field requests for help on Twitter, and officials are reportedly urging Houston residents trapped by floods not to take shelter in their attics, but to move to their roofs to make them easier to spot and rescue. Tornado warnings were issued for some surrounding counties, thanks to the disturbance in the atmosphere.

As history shows, Texas isn&rsquot always just bluebonnets and sunshine, sometimes weather here can get down-right messy.
Looking back at the major floods that sideswiped Texas, the state&rsquos rivers and reservoirs took a beating, from the Rio Grande to the Red River.
One of the biggest floods to hit Texas was in July 1869, when the Colorado River exceeded 55 feet due to a week-long rainfall that swelled streams across the state, according to the USGS. Heading south, the Colorado River&rsquos angry waters submerged small towns Bastrop and La Grange, both southeast of Austin.
But going into the 20th and 21st Centuries, floods in Texas caused hundreds of deaths and billions of dollars in property damage, as well as many reforms for waterway and dam structures.

Editors' note: This story was originally published in September 2018.
For the first time in eight years, the Federal Emergency Management Agency has released updated flood maps for Bexar County that show how susceptible neighborhoods are to flooding and are used to determine flood insurance rates.
The current maps available are preliminary, meaning the public can see them but insurance agencies cannot yet use them to establish rates. After a public comment period in early 2019, the maps will be made final, according to a FEMA flood plain official.
In Bexar County, areas near the Airport Tributary, on the west side of the airport, the Fort Sam Tributary, to the east of Terrell Hills, and Martinez Creek, around the Beacon Hill Linear Park, will be affected, according to San Antonio River Authority Senior Engineer Erin Cavazos.
The flood maps are essentially a snapshot in time, showing the current likelihood of experiencing a flood rather than predicting the future, a FEMA flood plain official said. Areas with a 1 percent or higher risk of experiencing flooding are considering high risk, and insurance rates may vary accordingly.
Areas with less than a 1 percent chance of flooding are considered moderate- or low-risk. With heavy rain or tropical storms, however, any part of the city can flood.
"It is important for property owners outside of high-risk areas to be prepared," a FEMA flood plain official said in an email. "Eighty-one percent of the owners of Hurricane Harvey-damaged property outside of the high risk flood areas did not have a flood insurance policy."
The preliminary maps are issued several months before the final maps are released in order to give property owners plenty of time to find errors and report them and to speak to insurance agents about how the new maps may affect their rates. Errors can range from misspelled street names to inaccurate floodplain boundaries, if the complainant provides technical data to support the case, Cavazos said.
The public comment in 2019 will be preceded by a notice in the Federal Register as well as two public notices in each community's newspapers. The public will then have 90 days to note errors.
In addition to updating the Bexar County maps, FEMA also released preliminary maps for Bandera, Kendall, Kerr and Medina Counties, which were last issued maps in 2011.
&ldquoAt that time, most of the panels were digitized from paper maps but not restudied,&rdquo Cavazos said in an email, adding that there have been smaller area updates through the letter of map revision process since then.
In Bandera County, FEMA and local authorities restudied the majority of the county. In Medina County, they restudied the Medina River through Castroville and up to the Medina Dam, as well as its tributaries, Cavazos said. Minimal restudy was performed in Kerr and Kendall Counties.
