Drainage requirements in Fort Worth depend on the scope and impact of a project. Not every development requires a full drainage study, but many projects must demonstrate how stormwater runoff will be managed.
In general, a drainage study may be required when:
• The site is being significantly regraded
• Impervious area is increased
• Runoff patterns are altered
• The project connects to public drainage infrastructure
The City of Fort Worth reviews how development affects stormwater conditions and may require supporting calculations or reports as part of the submittal.
For smaller projects, this may be limited to basic calculations. Larger or more complex sites may require a more detailed analysis.
Confirming drainage requirements early helps avoid delays and ensures the project scope accounts for any necessary design work.
