Trails + Permits Update

By March 17, 2018

Special Operating Permits

A special operating permit is required for any commercial activity or event on Tarrant Regional Water District (“TRWD”) property.  TRWD property includes 72 miles of Trinity Trails. To view a map of the Trinity Trails that is considered TRWD property, click here:

In an effort to assist with trail congestion and overall trail usage awareness, any event with 100 participants or more that has received an executed permit from TRWD will be included on the TRWD Recreation Calendar found here: as well as the TRWD Smart Phone App.

Effective October 1, 2017, any event that has been issued a permit by TRWD to utilize the Trinity Trails and does not start/stop within parks owned by the City of Fort Worth will be required to pay a “Trail Impact” fee and Refundable Security Deposit. Fee schedule is available upon request.

≤100 Participants

Usage of the Trinity Trails for any run, walk or cycling event with 100 or more participants must submit a Trail Permit Application and proposed route to TRWD within a minimum of 60 days of the proposed event date.  Event date and route will be reviewed for any potential conflicts with other events along the Trinity Trails.  If approved, a permit will be issued and event producer must add TRWD as an additional insured on event’s certificate of liability insurance.  Requirements will be provided.


>100 Participants

Usage of the Trinity Trails for any run, walk or cycling event with less than 100 participants is considered more of a “social gathering” and does not require a permit issued from TRWD.  However, as a courtesy, TRWD would still like to be informed of these smaller groups so that we can help keep these groups informed of any larger events that may be taking place at the same time as well as to help prevent any potential collisions along the trails between the smaller and larger groups.
