The National Flood Insurance Program (NFIP) is a program created by the Congress of the United States in 1968 through the National Flood Insurance Act of 1968 (P.L. 90-448). The NFIP has two purposes: to share the risk of flood losses through flood insurance and to reduce flood damages by restricting floodplain development. The program enables property owners in participating communities to purchase insurance protection, administered by the government, against losses from flooding , and requires flood insurance for all loans or lines of credit that are secured by existing buildings, manufactured homes, or buildings under construction, that are located in the Special Flood Hazard Area in a community that participates in the NFIP. U.S. Congress limits the availability of National Flood Insurance to communities that adopt adequate land use and control measures with effective enforcement provisions to reduce flood damages by restricting development in areas exposed to flooding.

82-469: Flood insurance was generally provided by private insurers beginning in 1895, but after the Great Mississippi Flood of 1927 , most private insurers concluded that flood risk was uninsurable at a price that consumers could afford given the catastrophic nature of flooding, as well as difficulties in creating accurate risk assessments for policy pricing and risks of adverse selection . The NFIP

164-440: A Letter of Map Amendment (LOMA) uses an Elevation Certificate (prepared by a Registered Land Surveyor or Registered Professional Engineer) to ask FEMA to remove the flood insurance requirement on individual properties. FEMA's website "Change a Flood Zone Designation – Online Letter of Map Change" says homeowners and other interested parties may submit an Online Letter of Map Change (LOMC). FEMA says this can be used for property that

246-596: A combination of bureaucratic resources and grassroots forces to give the tent cities the opportunity to become self-sufficient. This method presented difficulties, as rural leaders were unprepared to manage the chaotic circumstances found in large camps. This led Hoover eventually to place the relief camps under government supervision. The refugee camps also dealt with extreme racial inequality, as supplies and means of evacuation after flooding were given strictly to white citizens, with Blacks receiving only leftovers. African Americans also did not receive supplies without providing

328-583: A disaster occurs, FEMA makes payments to those private insurance companies to offset their costs. However, there is little oversight and few rules as to how the money should be distributed. As a consequence, private insurers have been known to use FEMA payments to hire attorneys that fight policyholders in court. One law firm is estimated to have received US$ 29M from FEMA payments to fight Hurricane Sandy claims. President Barack Obama , on January 30, 2015, issued Executive Order 13690 requiring Flood Risk Management to anticipate flooding increases over time due to

410-490: A half-foot or tenth of a foot instead of the NFIP minimum standard increase of one foot. This 44 C.F.R. § 60.22 says community flood plain management regulations should permit only development in flood-prone areas that is appropriate with the probability of flood damage. Flooding can damage underground storage tanks (USTs) resulting in leaks of petroleum that contaminate soil, surface water, and groundwater. USTs may even float out of

492-496: A major flood in 1937. To better study and plan for future situations, Lt. Eugene Raybold proposed laying out a physical hydraulic model to simulate the basin's response to various rainfall scenarios. Land was procured at the SE edge of Clinton, Mississippi , and a 200-acre hydraulic model was constructed, matching to the river's flow from Baton Rouge to Omaha , modeling the confluence points of its major tributaries across 16 states. The work

574-413: A manner that is "mutually consistent" with NMFS's programs. Prior to the program, property losses resulting from flood damage were largely the responsibility of individual property owners, although some losses were sometimes mitigated through provisions for disaster relief aid. Today, owners of property in flood plains frequently receive disaster aid and payment for insured losses, which in many ways negates

656-539: A mechanism to obtain FEMA feedback on the project before site changes are made, especially in light of the increasing attention on the nexus between the NFIP and the Endangered Species Act. 44 C.F.R. § 65.6(10) says "A revision of flood plain delineations based on topographic changes must demonstrate that any topographic changes have not resulted in a floodway encroachment." FEMA says that justifiable encroachment within

738-697: A relief boat at gunpoint. Near Helena, Arkansas , Owen Flemming was lynched after he killed a plantation overseer, who wanted to force him to rescue the plantation owner's mules. As a result of displacements lasting up to six months, tens of thousands of local African Americans moved to the big cities of the North, particularly Chicago ; many thousands more followed in the following decades. Herbert Hoover enhanced his reputation by his achievements in directing flood relief operations as Secretary of Commerce under President Calvin Coolidge . The next year Hoover easily won

820-501: A request for conditional approval of map change, an evaluation of alternatives, a request for revision of base flood elevation determination, and a request for floodway revision. All requests for revision of base flood elevations must include supporting data with "all the information FEMA needs to review and evaluate the request. This may involve the requestor’s performing new hydrologic and hydraulic analysis and delineation of new flood plain boundaries and floodways, as necessary." Details of

902-405: A result of flooding. Monetary damages due to flooding reached approximately $ 1 billion, which was one-third of the federal budget in 1927. If the event were to have occurred in 2023, the damages would total around $ 1.38 trillion to $ 1.48 trillion. The flood affected Missouri , Illinois , Kansas , Tennessee , Kentucky , Arkansas , Louisiana , Mississippi , Oklahoma , and Texas . Arkansas

984-405: Is an example of adverse selection . Some factors contributing to increased demand for aid are: Some critics want the NFIP restricted to primary residences, excluding secondary vacation homes and investment properties. According to critics of the program, the government's subsidized insurance plan "encouraged building, and rebuilding, in vulnerable coastal areas and floodplains." Stephen Ellis, of

1066-516: Is in the USC section "Prohibition against Federal approval of financial assistance" that says "No Federal officer or agency shall approve any financial assistance for acquisition or construction purposes on and after July 1, 1975, for use in any area that has been identified by the Administrator as an area having special flood hazards unless the community in which such area is situated is then participating in

1148-409: Is limited to communities that adopted adequate land use and control measures with effective enforcement provisions consistent with these purposes. The USC section "Additional Congressional findings and declaration of purpose" says "property acquired or constructed with grants or other Federal assistance may be exposed to risk of loss through floods, thus frustrating the purpose for which such assistance

1230-625: Is managed and administered by the Federal Emergency Management Agency (FEMA) through the Federal Insurance and Mitigation Administration (FIMA). The program is designed to provide an insurance alternative to disaster assistance to meet the escalating costs of repairing damage to buildings and their contents caused by floods. As of August 2017, the program insured about 5 million homes (down from about 5.5 million homes in April 2010),

1312-457: Is sufficient to qualify as an "agency action." In neither the present case nor NWF v. Coleman does the action agency authorize, permit, or carry out the actual development that causes the harm to the species' habitat; however, in both cases, development is "reasonably certain to occur" as a result of the agency's action.

Flooding peaked in the Lower Mississippi River near Mound Landing, Mississippi , and Arkansas City, Arkansas , and broke levees along the river in at least 145 places. The water flooded more than 27,000 square miles (70,000 km ) of land, and left more than 700,000 people homeless. Approximately 500 people died as

1886-617: The Republican 1928 nomination for President, and the general election that year. In upstate Louisiana, anger among yeomen farmers directed at the New Orleans elite for its damage of downriver parishes aided Huey Long 's election to the governorship in 1928. Hoover was much lauded initially for his masterful handling of the refugee camps known as "tent cities". These densely populated camps required basic necessities which were difficult to attain, such as water and sanitation facilities. Hoover used

1968-607: The independent agencies of the United States government are also classified as executive agencies (they are independent in that they are not subordinated under a Cabinet position). There are a small number of independent agencies that are not considered part of the executive branch, such as the Congressional Research Service and the United States Sentencing Commission , which are legislative and judicial agencies, respectively. The U.S. Congress

2050-486: The 325,146 who occupied the relief camps were African American. In one location, over 13,000 evacuees near Greenville, Mississippi , were gathered from area farms, and evacuated to the crest of the unbroken Greenville Levee. But many were stranded there for days without food or clean water. Following the Great Flood of 1927, multiple states needed money to rebuild their roads and bridges. Louisiana received $ 1,067,336 from

2132-519: The Association of State Floodplain Managers stated "Most local governments have simply assumed that the federal floodplain management approaches embody a satisfactory standard of care, perhaps not realizing that they actually induce additional flooding and damage." In 2000, the Association of State Floodplain Managers recommended a "no adverse impact" goal to prevent one property owner from adversely impacting

2214-495: The NFIP and oversees the floodplain management and mapping components of the Program. The intent was to reduce future flood damage through community floodplain management ordinances and provide protection for property owners against potential losses through an insurance mechanism that requires a premium to be paid for the protection. In 2003, the GAO found that repetitive-loss properties cost

2296-429: The NFIP cumulative debt was over $ 17 billion. A core principle of Biggert-Waters was to change the NFIP premiums to match actuarial risk-based premiums that better reflected the expected losses and real risk of flooding. These changes included removing discounts to many policies which were being sold below actual actuarial risk targets and eliminating "grandfathering" of older rates. In March 2014, President Obama signed

2378-491: The NFIP in the section "Congressional findings and declaration of purpose" includes: It is the further purpose of this chapter to (1) encourage State and local governments to make appropriate land use adjustments to constrict the development of land which is exposed to flood damage and minimize damage caused by flood losses, (2) guide the development of proposed future construction, where practicable, away from locations which are threatened by flood hazards National Flood Insurance

2460-641: The NFIP is based on an agreement between local communities and the federal government that states that if a community will adopt and enforce a floodplain management ordinance to reduce future flood risks to new construction in Special Flood Hazard Areas (SFHA), the federal government will make flood insurance available within the community as a financial protection against flood losses. The SFHAs and other risk premium zones applicable to each participating community are depicted on Flood Insurance Rate Maps (FIRMs). The Mitigation Division within FEMA manages

2542-411: The NFIP. In October 2021, FEMA issued a public request for information to upgrade the NFIP. Great Mississippi Flood of 1927 The Great Mississippi Flood of 1927 was the most destructive river flood in the history of the United States, with 27,000 square miles (70,000 km ) inundated in depths of up to 30 feet (9 m) over the course of several months in early 1927. The period cost of

2624-610: The National Flood Insurance Program (NFIP) to indicate the minimum level of flooding to be used by a community in its floodplain management regulations." FEMA explains regulatory floodplains in some places including hills as "critical determinations are made by evaluating your community’s rainfall and river flow data, topography, wind velocity, tidal surge, flood control measures, building development (existing and planned) and community maps." Scientists and engineers use statistical analysis of streamflow data to determine

2706-560: The National Flood Insurance Program. From 2006, the NFIP has been directed by its Senior Executive, David Maurstad . A former Lieutenant Governor of Nebraska , he also serves as the Deputy Associate Administrator for FEMA's Federal Insurance and Mitigation (FIMA) division. The program was first amended by the Flood Disaster Protection Act of 1973, which made the purchase of flood insurance mandatory for

2788-431: The U.S. as of December 2020. The Federal Emergency Management Agency (FEMA) defines the floodplain as the area that would be flooded by a base flood , which is "the flood which has a one percent chance of being equaled or exceeded in any given year". In this sense, a base flood is synonymous with a 100-year flood and a floodplain is synonymous with a special flood hazard area . This base flood "is used in

The judicial branch includes the following agencies: The President of the United States is the chief executive of the federal government. He is in charge of executing federal laws and approving, or vetoing, new legislation passed by Congress. The President resides in

2952-469: The United States was well aware of flooding potential along the Mississippi, which drained 40% of the nation's area. The Mississippi River Commission was established by the federal government in 1879, with the directive to deepen the river channel, improve navigation, prevent major flooding, and increase river-based commerce. This commission recommended raising extensive levees along its channels to contain

3034-411: The connecting piping releasing the gas. Leaking propane tanks create fire hazards during floods. A court finds that local governments might have immunity for negligent emergency response activities because in an emergency there may not be time to determine the best course of action. However, there may not be grounds for immunity for pre-emergency actions where negligence results in flooding. In 2004

3116-459: The damage has been estimated to be between $ 246 million and $ 1 billion, which ranges from $ 4.2–$ 17.3 billion in 2023 dollars. About 500 people died and over 630,000 people were directly affected; 94% of those affected lived in Arkansas , Mississippi , and Louisiana , especially in the Mississippi Delta region. 127 people died in Arkansas , making it one of the deadliest disasters ever recorded in

3198-407: The date such information becomes available, a community shall notify the Administrator of the changes by submitting technical or scientific data in accordance with this part. Such a submission is necessary so that upon confirmation of those physical changes affecting flooding conditions, risk premium rates and flood plain management requirements will be based upon current data." FEMA requires "Copies of

3280-583: The destruction of the Caernarvon levee was unnecessary; several major levee breaks well upstream of New Orleans, including one the day after the demolitions, released major amounts of flood waters, reducing the water that reached the city. The New Orleans businessmen did not compensate the losses of people in the downriver parishes. To address the disaster, Congress passed the Mississippi Flood Control Act, which put greater stress on construction in

3362-423: The direct and indirect support of floodplain development whenever there is a practicable alternative. For those activities which in the public interest must occur in or impact upon floodplains, the district engineer shall ensure, to the maximum extent practicable, that the impacts of potential flooding on human health, safety, and welfare are minimized, the risks of flood losses are minimized, and, whenever practicable

During the 2015 United Nations Climate Change Conference , just prior to the signing of the Paris Agreement , on December 9, 2015, Reforming the National Flood Insurance Program was presented to members of Congress by Marsh & McLennan CEO Peter Zaffino , urging policymakers to enact reforms. A peer review study found climate change since 1900 may have increased

3526-466: The federal government built the world's longest system of levees and floodways. Then- Secretary of Commerce Herbert Hoover 's handling of the crisis gave him a positive nationwide reputation, helping pave the way to his election as U.S. President in 1928 . Political turmoil from the disaster at the state level aided the election of Huey Long as governor in Louisiana. By the late nineteenth century,

The Corps of Engineers was charged with taming the Mississippi River. Under the Flood Control Act of 1928 , the world's longest system of levees was built. Floodways that diverted excessive flow from the Mississippi River were constructed. While

This 44 C.F.R. § 60.22 says community flood plain management regulations should divert development to areas safe from flooding to prevent environmentally incompatible flood plain uses. Ruptures of crude oil pipelines result in crude oil contamination of floodplains. Oil spills create numerous environmental harms . Releases of gasoline, oil, or natural gas during floods also create fire hazards. This 44 C.F.R. § 60.22 says community flood plain management regulations should provide access requirements so that people do not become isolated by flood water. The Illinois Supreme Court found: Even if plaintiff were to successfully build

3772-596: The flood's figures were "staggering". Great loss of life was averted by relief efforts, largely by the American Red Cross through the efforts of local workers. African Americans, comprising 75% of the population in the Delta lowlands and supplying 95% of the agricultural labor force, were most affected by the flood. Historians estimate that of the 637,000 people forced to relocate by the flooding, 94% lived in three states: Arkansas, Mississippi and Louisiana; and that 69% of

3854-478: The floodplain might include "construction or modification of a bridge, culvert, levee, or similar measure". The NFIP prohibits communities to issue variances "within any designated regulatory floodway if any increase in flood levels during the base flood discharge would result". However, a community may request FEMA's prior approval for a justifiable encroachment that would increase the base flood level. This community request must include seven required submittals such as

3936-557: The flow, dismissing the advice of experts such as James Eads , who had directed the Saint Louis Bridge project in the 1860s. These critics predicted that compressing a swollen river between walls would increase its destructive potential. Flooding began due to heavy rainfall in summer 1926 across the river's central basin. By September, the Mississippi's tributaries in Kansas and Iowa were swollen to capacity. On Christmas Day of 1926,

4018-618: The ground during floods. This 44 C.F.R. § 60.22 says community flood plain management regulations should prohibit public utilities to be installed in flood prone areas unless it is essential to be located there. Leakage from on-site sewage systems cause contamination problems during floods. Sanitary sewer overflows and combined sewer overflows also release sewage contaminates into flood water. The U.S. Environmental Protection Agency advises "Avoid contact with flood water due to potentially elevated levels of contamination associated with raw sewage and other hazardous or toxic substances that may be in

4100-500: The group Taxpayers for Common Sense , points to "properties that flooded 17 or 18 times that were still covered under the federal insurance program" without premiums going up. Critics say this program is underperforming because it is starved for funding compared to disaster response and recovery, and the process of applying for a buyout is unreasonably slow. Another criticism is that FEMA does not administer all policies, instead outsourcing many policies to private insurance companies. When

4182-543: The input and output data from the original and revised hydraulic analyses shall be submitted" with the hydraulic analysis supporting revisions to flood maps. A 2015 FEMA website identifies that the U.S. Army Corps of Engineers (USACE) Hydrologic Engineering Center's River Analysis System (HEC-RAS) computer program has been adopted for the preparation of studies and restudies for the NFIP. The U.S. Congress finds annual flood losses are "increasing at an alarming rate" and forms of Federal assistance "are often determining factors in

4264-573: The landscape topography is different from that shown on the floodplain boundary and/or flood heights shown on the FIRM and the Flood Insurance Study. A Letter of Map Revision based on Fill (LOMR-F) is used when landscape topography is altered by humans, usually to increase the land elevation and remove land from the floodplain. A Conditional Letter of Map Revision (CLOMR) and Conditional Letter of Map Revision Based on Fill (CLOMR-F) are strongly advised as

4346-440: The levees prevented some flooding, scientists have found that they changed the flow of the Mississippi River, with the unintended consequence of increasing flooding in succeeding decades. Channeling of waters has reduced the absorption of seasonal rains by the floodplains, increasing the speed of the current and preventing the deposit of new soils along the way. The levees did not prevent recurrences of significant flooding, especially

4428-428: The likelihood of flood elevations. Theoretically a 100-year flood has a 1 percent chance (1/100 = 0.01 or 1 percent) of occurring in any given year and a 500-year flood has as a 0.2 percent chance (1/500 = 0.002 or 0.2 percent) of occurring in any given year. However, these expected flood elevations actually occur more or less often than expected. 44 CFR § 9.4 defines parts of the floodplain as follows: Participation in

4510-487: The majority of which are in Texas and Florida. The cost of the insurance program was fully covered by its premiums until the end of 2004, but it has had to steadily borrow funds since, primarily due to Hurricane Katrina and Hurricane Sandy , accumulating $ 25 billion of debt by August 2017. In October 2017, Congress cancelled $ 16 billion of NFIP debt, making it possible for the program to pay claims. The NFIP owes $ 20.525 billion to

The program was further amended by the Flood Insurance Reform Act of 2004 , with the goal of reducing "losses to properties for which repetitive flood insurance claim payments have been made." The Biggert–Waters Flood Insurance Reform Act of 2012 (Biggert-Waters) modified the NFIP. At the conclusion of 2011, as Congress passed Biggert-Waters,

In order to fully exploit black labor, Blacks were frequently forced to work against their will, and were not permitted to leave the camps. Later reports about the poor treatment in camps led Hoover to make promises of change to the African-American community, which he broke. As a result, he lost the Black vote in the North in his re-election campaign in 1932. Several reports on

While the Administrative Procedure Act definition of "agency" applies to most executive branch agencies, Congress may define an agency however it chooses in enabling legislation, and through subsequent litigation often involving

4838-409: The national flood insurance program." FEMA created a regulation that identifies the minimum flood plain management criteria for communities including the following: The Code of Federal Regulation (CFR) "Suspension of community eligibility" says communities that do not adequately enforce flood plain management regulations meeting the minimum requirements shall be placed on probation. Failure to correct

4920-508: The natural and beneficial values served by floodplains are restored and preserved. U.S. Congress requires FEMA to consult with other departments and agencies of the Federal Government, and with interstate, State, and local agencies responsible for flood control in order to make certain that those agencies' programs are consistent with the National Flood Insurance Program (NFIP). For example, a U.S. District Court ordered FEMA to consult with

5002-406: The original intent of the NFIP. Consequently, these policy decisions have escalated losses stemming from floods in recent years, both in terms of property and life. Moreover, certain provisions within the NFIP increase the likelihood that flood-prone properties will be occupied by the people least likely to be in a position to recover from flood disasters, which further increases demand for aid.

The 33 C.F.R. 320.4(l)(2) states: In accordance with the requirements of Executive Order 11988, district engineers, as part of their public interest review, should avoid to the extent practicable, long and short term significant adverse impacts associated with the occupancy and modification of floodplains, as well as

5412-736: The protection of property within SFHAs. In 1982, the Act was amended by the Coastal Barrier Resources Act (CBRA). The CBRA enacted a set of maps depicting the John H. Chafee Coastal Barrier Resources System (CBRS) in which federal flood insurance is unavailable for new or significantly improved structures. The National Flood Insurance Reform Act of 1994 codified the Community Rating System (an incentive program that encourages communities to exceed

5494-421: The required supporting data are listed in 44 C.F.R. § 65.7 . The U.S. Geological Survey says increased runoff resulting from urban growth generally increases flood hazards to communities and that flood hazard maps based on data before urban growth may no longer be accurate. The U.S. Geological Survey gives the example that construction encroaching into the floodplain narrows the floodplain width thereby increasing

5576-592: The resistance to flow. Consequently, the water is at a higher stage as it flows past the construction causing backwater to flood a larger area upstream. FEMA's computer model image shown here "represents the percent chance of flooding at least one time during a 30-year period for a given cell, or location, within the mapped floodplain".

On 29 April they arranged to set off about 30 tons of dynamite on the levee at Caernarvon, Louisiana , releasing 250,000 cu ft/s (7,000 m /s) of water. This was intended to prevent New Orleans from suffering serious damage, and it resulted in flooding much of the less densely populated St. Bernard Parish and all of Plaquemines Parish 's east bank. As it turned out,
