Flood Preparedness and Response

• Emergency Preparedness and Response

Introduction

Floods can be serious catastrophes and they are one of the most common hazards in the United States. Floods can be caused by a variety of factors, including a sudden accumulation of rain, rising rivers, tidal surges, ice jams and dam failures.

OSHA and NOAA are working together on a public education effort aimed at improving the way people prepare for and respond to severe weather. This page is designed to help businesses and their workers prepare for floods, and to provide information about hazards that workers may face during and after a flood event.

Workers who have to respond to flooded areas face the greatest risks from floods, but all workers can help protect themselves by preparing evacuation plans and learning about the hazards commonly associated with floods.

This planning information can help you ensure that you are ready to evacuate in an orderly manner before rising waters impact your business or residence, or your evacuation routes.

The Response/Recovery page provides useful details on the hazards to avoid when flooding has occurred. This includes areas to avoid when using a vehicle, and safety and health hazards such as downed electrical lines, mold and wild animals.

Employer Responsibilities and Workers' Rights

Each employer is responsible for the safety and health of its workers and for providing a safe and healthful workplace for its workers. Employers are required to protect workers from the anticipated hazards associated with the flood response and recovery operations that workers are likely to conduct.

Flood Insurance

OSHA's role is to assure the safety and health of America's workers. The OSHA at a Glance publication provides information on the strategies and programs OSHA uses to promote worker safety and health. For additional information on Workers' Rights, Employer Responsibilities, and other services OSHA offers, visit OSHA's Employers Page, Workers Page and Publications.

Highlights

OSHA provides comprehensive worker safety and health resources for protecting workers from many different hazards associated with storm response and recovery. See the Worker Safety and Health Resources for Hurricanes and Flood Cleanup and Recovery for an up-to-date listing of these OSHA web pages, Fact Sheets and QuickCards™, along with interagency and OSHA alliance partner publications.

Cleaning Up, Staying Safe. U.S. Department of Labor Blog Post (September 6, 2017). Hurricane Harvey brought catastrophic flooding to Texas and Louisiana last week, but it also brought heroic reactions from first responders and volunteers. As the flood waters recede, thousands of Americans are beginning the difficult work of cleanup and recovery.

What is flooding?

Flooding is an overflowing of water onto land that is normally dry. Floods can happen during heavy rains, when ocean waves come on shore, when snow melts quickly, or when dams or levees break. Damaging flooding may happen with only a few inches of water, or it may cover a house to the rooftop. Floods can occur within minutes or over a long period, and may last days, weeks, or longer. Floods are the most common and widespread of all weather-related natural disasters.
Flash floods are the most dangerous kind of floods, because they combine the destructive power of a flood with incredible speed. Flash floods occur when heavy rainfall exceeds the ability of the ground to absorb it. They also occur when water fills normally dry creeks or streams or enough water accumulates for streams to overtop their banks, causing rapid rises of water in a short amount of time. They can happen within minutes of the causative rainfall, limiting the time available to warn and protect the public.

Where and when do floods occur?

Flooding occurs in every U.S. state and territory, and is a threat experienced anywhere in the world that receives rain. In the U.S. floods kill more people each year than tornadoes, hurricanes or lightning.

What areas are at risk from flash floods?

Densely populated areas are at a high risk for flash floods. The construction of buildings, highways, driveways, and parking lots increases runoff by reducing the amount of rain absorbed by the ground. This runoff increases the flash flood potential.
Sometimes, streams through cities and towns are routed underground into storm drains. During heavy rain, the storm drains can become overwhelmed or plugged by debris and flood the roads and buildings nearby. Low spots, such as underpasses, underground parking garages, basements, and low water crossings can become death traps.
Areas near rivers are at risk from floods. Embankments, known as levees, are often built along rivers and are used to prevent high water from flooding bordering land. In 1993, many levees failed along the Mississippi River, resulting in devastating floods. The city of New Orleans experienced massive devastating flooding days after Hurricane Katrina came onshore in 2005 due to the failure of levees designed to protect the city.
Dam failures can send a sudden destructive surge of water downstream. In 1889 a dam break upstream from Johnstown, Pennsylvania, released a 30-40 foot wall of water that killed 2200 people within minutes.
Mountains and steep hills produce rapid runoff, which causes streams to rise quickly. Rocks and shallow, clayey soils do not allow much water to infiltrate into the ground. Saturated soils can also lead to rapid flash flooding. Camping or recreating along streams or rivers can be a risk if there are thunderstorms in the area. A creek only 6 inches deep in mountainous areas can swell to a 10-foot deep raging river in less than an hour if a thunderstorm lingers over an area for an extended period of time. Sometimes the thunderstorms that produce the heavy rainfall may happen well upstream from the impacted area, making it harder to recognize a dangerous situation.
Very intense rainfall can produce flooding even on dry soil. In the West, most canyons, small streams and dry arroyos are not easily recognizable as a source of danger. The causative rainfall can occur upstream of the canyon, and hikers can be trapped by rapidly rising water. Floodwaters can carry fast-moving debris that pose significant risks to life.
Additional high-risk locations include recent burn areas in mountains, and urban areas from pavement and roofs which enhance runoff.
Ice jams and snowmelt can help cause flash floods. A deep snowpack increases runoff produced by melting snow. Heavy spring rains falling on melting snowpack can produce flash flooding. Melting snowpack may also contribute to floods produced by ice jams on creeks and rivers. Thick layers of ice often form on streams and rivers during the winter. Melting snow and/or warm rain running into the streams may lift and break this ice, allowing large chunks of ice to jam against bridges or other structures. This causes the water to rapidly rise behind the ice jam. If the water is suddenly released, serious flash flooding could occur downstream. Huge chunks of ice can be pushed onto the shore and through houses and buildings.

National Weather Service Messaging Terminology

FLASH FLOOD WATCH or FLOOD WATCH

Flash flooding or flooding is possible within the designated watch area — be alert.

FLASH FLOOD WARNING or FLOOD WARNING

Flash flooding or flooding has been reported or is imminent — take necessary precautions at once! Get to higher ground!
Turn around, don’t drown! Most fatalities in the US from flash flooding are from vehicles driving into flooded roadways.

URBAN and SMALL STREAM ADVISORY

Flooding of small streams, streets and low-lying areas, such as railroad underpasses and urban storm drains is occurring.

FLASH FLOOD STATEMENT or FLOOD STATEMENT

Follow-up information regarding a flash flood/flood event.

What we do: In order to evaluate the forecasting tools, we need observations of flash flooding. NSSL has assembled flash flood observations from USGS automated discharge measurements, trained spotter reports from the NWS, and from NSSL's Severe Hazards Analysis and Verification Experiment (SHAVE). This database is available for community research purposes.

Flood Lights

NSSL has developed the state-of-the-science system for estimating heavy rainfall and resultant flash flooding. The Multi-Radar Multi-Sensor system provides rainfall rate estimates across the U.S. every two minutes, and these are input to a suite of hydrologic models and forecasting tools within the Flooded Locations and Simulated Hydrographs (FLASH) system.
