Drainage in Stonebridge Ranch and Trinity Falls
Stonebridge Ranch and Trinity Falls were built on the same Blackland Prairie clay as the rest of McKinney, but their scale and HOA/MUD structure add a layer most other neighborhoods don't deal with. Lots were graded during large-scale development phases, and drainage systems were designed community-wide rather than lot by lot — which means an individual yard's water problem sometimes traces back to how the whole section was graded, not just your property.
The 2025 MUD 2 Illegal Drain Letters
In early 2025, McKinney MUD 2 sent letters to homeowners in Trinity Falls flagging unauthorized drain outlets — specifically, underground drains that discharged straight through a cutout in the street curb. Curb cutouts weaken the curb over time and can cause standing water in the street. The MUD's guidance: a correctly installed underground drain should end in a pop-up emitter at least 5 feet from the property line, so water sheet-flows to the street instead of draining through the curb itself. If you received one of these letters, it doesn't necessarily mean your drain has to be relocated immediately — but it's worth having a local contractor confirm your setup meets the standard before it becomes a bigger issue.
HOA Drainage Expectations
Both communities have HOA architectural and maintenance guidelines that can apply to drainage work — altering the grade of your lot, adding a French drain, or changing where water exits your property may need to stay within HOA rules even when no city permit is required. A contractor experienced in Stonebridge Ranch or Trinity Falls will design a fix that solves the water problem without creating a new compliance headache.
Frequently Asked Questions
- I got a letter from McKinney MUD 2 about my drain — what do I do?
- Receiving a letter doesn't automatically mean you're required to fix anything — MUD 2 has stated it won't require relocation unless the unauthorized drain is actively causing curb or sidewalk damage. That said, it's worth having a contractor inspect the outlet and confirm it meets the standard (pop-up emitter, 5+ feet from the property line) before it becomes a bigger problem.
- Do I need HOA approval for a French drain in Stonebridge Ranch or Trinity Falls?
- Check your community's specific architectural guidelines — many McKinney HOAs require notice or approval for grading changes or new drainage structures, even when no city permit applies. Approval is usually straightforward but can take a few weeks, so plan ahead.
