Warn

All rivers, streams, tributaries, and ditches - regardless of size - have the potential to flood.  In Fort Worth, major sources of flooding include the...

• Clear Fork Trinity River
• West Fork Trinity River
• Mary's Creek, Marine Creek
• Village Creek, Dry Branch Creek
• Big Fossil Creek, Big Bear Creek
• Sycamore Creek
• White's Branch.

Hazardous flooding away from larger creeks and channels is also frequent within the City as stormwater runoff drains from upstream areas toward larger streams and channels.

Flooding in Fort Worth is typically produced by heavy rainfall from frontal type storms that occur during the spring and fall months. Flash floods are the most common type of flooding in Fort Worth. Those flood events can happen near rivers but also in urban areas, mostly inside the 820 loop.

The City continues to provide citizens with additional tools to identify and mitigate flood risk with the goal of protecting people and property from harmful stormwater runoff before, during, and after a flood event.

High Water Warning Flashers (HWWS)

	Purposes and Objective The flood warning system in Fort Worth, known as the High-Water Warning System (HWWS), relies on water level measurements made at approximately 55 low-water road crossings throughout the city. Roadside flashers immediately warn drivers of the flood hazard at these flood prone road crossings. View High Water Warning Flasher Locations Map Enhanced Text Alert Rising flood water at these HWWS sites trigger automated alarms which are sent to first responders. First responders place barricades to prevent vehicles from entering flooded streets. Drivers should not go around barricades and drivers should safely turn around when the flashers go off. Weather data, including rainfall measurements prior to flooding, is collected at 39 low-water crossings and 28 weather stations.

The Goals of the Flood Warning System

The Flood Warning System was developed through a Texas Water Development Board (TWDB) grant. The goals of the Flood Warning System project were:

• Improve system reliability
• Expand the gaging network with additional rain gaging sites
• Upgrade data collection and data dissemination (communication tool) software
• Develop a Flood Response Plan(PDF, 211KB)

Check If Your Property Is In a Floodplain or Non-FEMA Risk Area

Find out if your flood risk is low, moderate, or high before the next storm hits, so you can take steps to protect your home or business. The Federal Emergency Management Agency (FEMA) publishes Flood Insurance Rate Maps (FIRMs) which show the different flood zones that designate the risk.

To find your property, visit the One Address website and/or the Flood Risk Viewer and type in your address. You can also email floodplain@fortworthtexas.gov for assistance in determining flood risks or obtaining documents.

Due to the extensive reported flooding risks citywide outside of FEMA floodplains and the limited resources to help lessen these risks, a policy is necessary to provide city staff and the community with guidance for mapping, communication and regulating local flood risks. A Non-FEMA Flood Risk Area stakeholder working group was formed to help with guidance in forming a policy. For more information visit Non-FEMA Flood Risk Area.

Residents of Fort Worth can obtain flood information concerning flooding, flood maps, mandatory flood insurance purchase requirements, and flood zone determinations from the City of Fort Worth's Transportation & Public Works Department (Stormwater Management Division) located at City Hall or by calling 817-392-6261. 

Digital copies of Elevation Certificates (EC) for some properties are on file and available upon request by emailing floodplain@fortworthtexas.gov. If the City does not have an EC on file and one is needed for insurance or development purposes, you will need to hire a surveyor or engineer to complete it.

Real-time river gauge information is available through the National Weather Service.

The City of Fort Worth's Hazardous Road Overtopping Mitigation (HROM) Program is an ongoing effort to identify hazardous road locations due to flooding, prioritize them, and where feasible, develop solutions to make them safer. The HROM Program was created in response to life-threatening and fatal incidents associated with flooded roads, usually at stream crossings.
