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 that surpassed one million in 2025. This 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 $1 billion 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 2026 for single-family properties range from $3.65 per month for small homes with limited parking to $14.58 per month for large homes.
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 $7.29 per month.

High Occupancy Residential and Non-Residential Property Fees
The city uses digitized aerial photography to measure impervious (hard surface) areas of every developed parcel. Non-residential and high occupancy residential 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 $7.29
For High Occupancy Residential/Non-Residential Property such commercial and industrial properties, the monthly rate is $7.29 per billing unit (2,600 sf of hard surface = 1 billing unit).
For example, the fee for a small commercial property with a total hard
surface area of 1 acre or 43,560 square feet is $123.93 per month, effective January 1st, 2026
calculated as follows:
43,560 square feet ÷ 2,600 square feet/ERU = 16.75
billing units, rounded up to 17
17 billing units x $7.29 per month/ERU = $123.93 per month
