Stormwater Management


Protecting People and Property from Harmful Stormwater Runoff

When rain hits any hard surface, such as your roof or driveway, it can't soak into the ground so it runs off your property. Uncontrolled runoff can lead to flooding, erosion and pollution problems. It is the City's job to help manage this runoff. The City's Stormwater Management Program is working to improve the Fort Worth stormwater system and educate the public about the dangers of flash flooding. The Stormwater fee you pay through your monthly water bill provides funding to accomplish our Mission to Protect People and Property from Harmful Stormwater Runoff, in the following ways: 

Pipes, channels, and other systems maintenance.
existing systems of pipes
and channels to function
as designed.
Drainage construction and improvement
drainage and reduce
erosion through
construction of projects.
Flooding and erosion hazards warning flashers.
the public and property
owners of flooding and
erosion hazards.
Development and compliance review.

compliance with City
Stormwater standards.

Hazard Road Overtopping Mitigation (HROM)

The City of Fort Worth's Hazardous Road Overtopping Mitigation (HROM) Program is an ongoing effort to identify hazardous road location 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 flood roads, usually at stream crossings.

Non-FEMA Flood Risk Area

Flood Risk Outside of the FEMA Floodplain

Cleaning blocked inlets by TPW crew

While FEMA maps flood risk along major streams and creeks, most reported flooding in Fort Worth actually occurs outside of the FEMA Floodplain, in what the City refers to as “Non-FEMA Flood Risk Areas”. The City has categorized Non-FEMA Flood Risk Areas into two categories. Areas where the City has evaluated the non-FEMA flood risk in detail are called “City Flood Risk Areas” (CFRA), and these will be used to regulate development in the future. In contrast, the non-FEMA areas where the City has less detailed mapping, called “Potential High-Water Areas” (PHWA), are used to warn about potential flood risks.

In order to better protect property owners in CFRAs from flood risk, the City is revising the existing Floodplain Provisions Ordinance and Updating the Stormwater Criteria Manual. Currently, our regulations do not require Stormwater review for land disturbance less than one acre. With a revised ordinance however, new development and re-development in CFRAs would be required to show they comply with Stormwater regulations, regardless of size. Recommended Council adoption of the updates is planned to go forward spring 2023. A phased rollout of mapping to help communicate flood risk outside of the FEMA Floodplains is planned this year:


In the City of Fort Worth, there are more flood insurance policies and claims located outside FEMA floodplains than inside FEMA floodplains.

Potential High Water Areas (PHWA)

Potential High Water Areas (PHWA) are Non-FEMA Flood Risk Areas caused by natural drainage patterns where flooding is likely to occur. The City of Fort Worth uses PHWA mapping as advisory areas to inform residents and developers about flood risk.

Stormwater Management Program Master Plan

Cleaning blocked inlets by TPW crew

The Stormwater Management Program has completed an intensive, year-long effort to develop a strategic program master plan that is realistic, well-prioritized, and responsive to community needs. The overarching goal of this effort was to help ensure the optimal use of program resources to advance the City’s strategic goals and respond to community needs in each of the four primary program elements:

  • System maintenance
  • Flood/erosion mitigation
  • Flood/erosion warning and
  • Private development review

The plan also outlines formal policy guidance needs and identifies key considerations, which will be used in the future processes to develop each policy.

Stormwater Management Program Master Plan(PDF, 17MB)

The City Council has adopted the Stormwater Management Program Master Plan, which resulted from an intensive, yearlong effort to compile and understand lessons learned during the first 10 years of the program and to develop a strategic direction that is realistic, well-prioritized and responsive to community needs.

Program Background

The City of Fort Worth implemented a Stormwater Utility in 2006 to address a backlog of data and technology needs, fulfill maintenance obligations, and construct capital projects to protect people and property from harmful stormwater runoff. The first 10 years of the Stormwater Management Program have focused on assessing citywide flood risk and drainage system capacity, addressing many of the most hazardous flooding problems in the city, implementing a high water warning system, developing a work order system and maintenance program, and developing a basic inventory of the major components of the drainage system.

Cumulative Impacts of Development

Cumulative Impact BannerAll development within the City of Fort Worth requires local and state permits. Contact the City of Fort Worth’s Development Services Department at 817-392-2222 for advice before you build, fill, place a manufactured home or otherwise develop.

The zoning ordinance, Floodplain Provisions Ordinance and the International Building Codes have special provisions regulating construction and other developments within floodplains. Without these provisions, affordable flood insurance through the National Flood Insurance Program (NFIP) would not be available to property owners in the City of Fort Worth. Any development in the floodplain without a permit is illegal. Such activity can be reported to the City Call Center at 817-392-1234.

Video: Cumulative Impacts

Two Types of Cumulative Impacts

The Stormwater team has been investigating reports of increased flooding associated with new developments that meet current requirements for no offsite impacts. Two case studies were recently completed to quantify the potential impact of increased impervious surface and/or reduced valley storage. Case studies were performed in:

• Central Arlington Heights and Linwood Bailey: older urban watersheds with underground storm drain systems experiencing increasing
amounts of impervious surfaces.
• White's Branch: a mostly suburban watershed draining to a natural stream-based floodplain with a loss in valley storage.

Floodplain Management Plan

The City of Fort Worth is working on a Floodplain Management Plan for the entire city. This will be the first part of a growing public planning and interaction program being led by the Stormwater Management Division.

Planning and Spotlight tab icon Stormwater Utility Fee

Utility Fee Header Image

The stormwater utility is a monthly user fee that pays for maintenance, improvements to the stormwater drainage system and other stormwater program activities. This fee is similar to other utility fees for water, sewer, and garbage.

Why are properties in Fort Worth being charged a stormwater fee? Fort Worth is one of the fastest growing cities in the U.S. today, with a population predicted to exceed one million by 2025. This projected growth, coupled with a drainage system that is now decades old, presents new challenges and increased needs in order to control flooding and its impacts. In the past few years, eight people have lost their lives due to flooded roadways and over 300 homes and businesses have suffered major flood damage.

It is estimated that more than $1Billion is needed to mitigate flooding and high-water hazard areas and to improve maintenance. By providing a dedicated source of funds for these vital needs, the stormwater utility fee reduces the burden on city's general revenue bond program and tax revenue funds, and decreases the need for future tax increases.

Who is charged this fee? Owners of developed property in Fort Worth are charged a user fee for stormwater services. This includes residential property owners, businesses, apartment complexes, public facilities, city owned facilities and churches.

How is this fee determined? The stormwater fee is calculated based on the amount of hard surface on your property. If you own a single-family residence, your property is placed in one of four tiers depending on the square footage of your home. The fees effective January 2020 for single-family properties range from $2.88 per month for small homes with limited parking to $11.50 per month for large homes.

Single-Family Residential Fees: Each residence is placed in one of four tiers according to square footage. For example, a 1,600 square foot residential property falls into Tier 2 and is charged $5.75 per month.

2,476 to 3,394 square feet

$ 8.63

Tier 4

2.0 ERU

3,394+ square feet



Non-Residential and Multi-Family Fees:

The city uses digitized aerial photography to measure impervious (hard surface) areas of every developed parcel. Non-residential and multi-family fees are based on the amount of hard surface area on the property. Hard surface area includes buildings, sidewalks, driveways and parking lots. Hard surface area will be divided by the standard Equivalent Residential Unit (ERU) of 2,600 square feet to determine the number of billing units on the property. The number of billing units then will be multiplied by the standard ERU rate of $5.75.

For example, the fee for a commercial property with a total hard surface area of 25,000 square feet will be $57.50 monthly, calculated as follows:

25,000 square feet ÷ 2,600 square feet/ERU = 9.6 billing units or about 10 billing units.

10 billing units x $5.75 per month/ERU = $57.50 per month.


Proposed FY24 Stormwater Utility Fee Increase

To help fulfill our Mission to Protect People & Property from Harmful Stormwater Runoff”, the Stormwater Program is proposing a 15% utility fee increase, to be split 50/50 between drainage Capital Improvement Projects and drainage Maintenance. If approved by Council, the increase would go into effect on January 1, 2024.

Floods can happen anywhere and at anytime.

To learn more about your risk for flooding and how to prepare for floods, visit or email

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 and type in your address. You can also email 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.
