Water/Wastewater Impact Fees Frequently Asked Questions

Is this a new fee?

  • No. Fort Worth has been collecting these fees since 1990. Senate Bill 336, passed by the Texas Legislature in 1987, authorized cities to use impact fees as a source of funding. The Senate Bill specifies what expenditures are qualified to receive impact fee funding and sets forth a formula for calculating the maximum allowable rate.
  • In 1990, the Fort Worth City Council adopted Ordinance No. 10601, authorizing the assessment of impact fees in the Fort Worth Water Department’s service area and establishing guidelines to ensure the fees are assessed, collected and disbursed fairly and within the law.

Why did the city council decide to collect impact fees?

  • Before these fees were authorized, the costs associated with expanding Fort Worth Water Department facilities were borne by all of the department’s customers. Now, through the use of impact fees, the developers who create the additional demand are paying a portion of the cost of meeting that demand. This helps reduce rate increases that all customers must pay and ensures that those who place additional demand on the water and wastewater systems help pay the costs required.

Do only Fort Worth customers pay impact fees?

  • No. Impact fees are charged to all new service within Fort Worth’s Utility Service Area. This includes all residences and businesses located within Fort Worth’s city limits as well as surrounding communities and utility districts served by the Fort Worth Water Department.
  • Irrigation meters must pay the water impact fee, but the wastewater impact fee does not apply. There are no impact fees on fire lines.
  • Most communities also have adopted ordinances allowing them to impose impact fees on new development within their jurisdictions. Each city or authority sets its own rates, which may be different from those charged by the City of Fort Worth. Contact local building officials for information on impact fees in areas outside Fort Worth’s corporate limits.

How are water and wastewater impact fees determined?

  • Water and wastewater impact fee updates are conducted as required by City Ordinance 10601 and Chapter 395 of the Texas Local Government Code.
  • These updates include revising forecasts of how population and land use throughout the service area are expected to change. The revised Land Use Assumptions take into account the latest projections made by the North Central Texas Council of Governments. Next, Capital Improvements Plans are drafted that identify the improvements that will be needed to meet projected demand. This includes Fort Worth’s own projects as well as its share of growth-related capital improvements for the Tarrant Regional Water District and the Trinity River Authority. Fort Worth has contractual obligations to these entities for water supply acquisition and wastewater treatment services, respectively. Also, interest costs on growth-related debt financing are factored into the overall CIP costs. These costs are allowable by state law.
  • Finally, the maximum impact fees are calculated by dividing the cost of capital improvements that will be required by future growth by the number of service unites, or meters, projected in the revised Land Use Assumptions.
  • The entire process is overseen by the Capital Improvements Plan Advisory Committee, appointed by the Fort Worth City Council. The committees’ involvement is intended to ensure that the updates are conducted legally and fairly reflect existing and projected conditions.
  • State law requires that a public meeting be held before the city council adopts any change in the impact fees. The city council has the authority to adopt any fee rate that does not exceed the maximum allowable rate determined by the Impact Fee Update. The Fort Worth City Council adopted a rate lower than the maximum allowable rate.

Do impact fees apply to existing development?

  • Only if an additional demand is being placed on the public system. For example, if a larger meter is installed in an existing home for a swimming pool or irrigation system, an impact fee is assessed based on the difference between the sizes of the old meter and new meter.
  • If a business or individual chooses to switch service from a private water well or a septic tank to the city’s water and/or wastewater system, then the customer charged an impact fee.

What is the difference between an impact fee and a tap fee?

  • A tap fee is a service fee that is charged for installing the service line from the public water or sewer main to the private plumbing. (See diagram below)
  • An impact fee is charged to new development to offset new or increased demands that require additional capacity improvements on existing water and wastewater systems. Impact fees are used only to fund expansion of the water and wastewater systems.
