Transportation Impact Fee Calculation

The maximum transportation impact fee allowed under state law, based on service area and land use, is shown on Schedule 1(PDF, 121KB) This amount represents a development’s actual impact on the transportation network, and is the basis for the Impact Fee Assessment.

The Transportation Impact Fee Estimator is simple to use.

  • Enter the development’s Service Area
  • Enter the plat approval date. If unknown, you can research the plats here.
  • Enter the appropriate building permit application date.
  • Enter the appropriate land use(s) from the drop-down list.
  • The applicable development unit will automatically appear, (for example, the development unit for an office is 1,000 sq ft; 2,500 sq ft office would be 2,500/1,000 = 2.5 development units; for a residential development, it is the number of dwelling units).
  • Enter the number of development units for each land use.
  • Enter credit / discount amounts, if known.
  • The program will calculate the project’s estimated transportation impact fee.

Collection Rate

The impact fee due on any given development, known as the collection rate, is also dependent upon service area and land use. The collection rate is shown on Schedule 2(PDF, 142KB). The collection rate falls between 0-100 percent of the maximum impact fee (Schedule 1), as adopted by the Fort Worth City Council. On average, City Council adopted 24 percent of the maximum for residential land uses and 18 percent of the maximum for non-residential land uses.


The Schedule 2 impact fee otherwise due for any given development may be reduced by the application of credit for the dedication of right-of-way or the construction or funding of eligible transportation facilities. The credit allowance will be based on an executed Credit Agreement, to be negotiated and approved by the Development Services Department. Applications for credit against transportation impact fees should be made to the Project Facilitation division of the Planning and Development Department. Contact Mirian Spencer with any questions.


The amount of transportation impact fees due under Schedule 2 may also be reduced by the application of the following discounts, where eligible:

  1. Adequate Public Facilities - A discount of 50 percent is available for those projects that are planned along an arterial facility identified on the Master Thoroughfare Plan that has either been built to its ultimate capacity or will be built to its ultimate capacity within 24 months of the date of final plat approval. Eligibility for this discount must be determined no later than final plat approval.
  2. Land use/Transportation connection – The amount of transportation impact fees due under Schedule 2 shall be reduced up to 15 percent for any development where a traffic study approved by TPW demonstrates that the development will produce fewer trips than what is anticipated for will a given land use in the adopted land use equivalency table of the Transportation Impact Fee Report, according to the following:
    • 5 to 9 percent Trip Capture: 5 percent Impact Fee Reduction
    • 10 to 14 percent Trip Capture: 10 percent Impact Fee Reduction
    • 15 percent or > Trip Capture: 15 percent Impact Fee Reduction
  3. Extraordinary investment – The amount of transportation impact fees due under Schedule 2 shall be reduced 15 percent for any development that results in the following qualifications, as jointly determined by Development Services and the Housing and Economic Development Departments:
    • $15 Million in capital investment (excluding land acquisition);
    • Creation of 100 new jobs; and
    • The projected salary of the new jobs is at least twice the current minimum wage, plus benefits.

For each additional $15 Million in capital investment or additional 100 qualified new jobs, the impact fee amount due under Schedule 2 will be further reduced by an additional 5 percent, up to a maximum reduction of 50 percent.

Discounts are cumulative, so that a development that qualifies for the maximum discount under each provision may reduce the amount of transportation impact fees due under Schedule 2 up to 100 percent. The applicant for a discount described above has the burden of proof to show that the development qualifies for the discount.

An application is required for the land use/transportation and extraordinary investment discounts.
