Surface Drainage Solutions in Kerrville, TX

Water running across the surface of your yard toward the house is a drainage problem that can often be fixed without installing underground systems. Regrading problem areas or adding swales to redirect flow is sometimes the most efficient and cost-effective solution — especially when a french drain is overkill for the situation.

Kerrville sits in the Texas Hill Country along the Guadalupe River, on thin, rocky Edwards Plateau limestone soil that's fundamentally different from the deep clay found through most of the rest of Central and North Texas — shallow topsoil over fractured limestone that drains fast at the surface in some spots while creating karst-influenced flash flooding in others. The Hill Country's steep terrain and thin soil are notorious for producing some of the fastest, most dangerous flash-flood conditions in the state, since limited soil depth means rainfall runs off toward low points and creek beds almost immediately rather than soaking in. Kerrville's older river-adjacent neighborhoods and newer hillside subdivisions both contend with that fast-runoff character in different ways.

When Surface Regrading Is Enough

If the problem is water flowing across the surface toward the house — from a sloped lot, a neighboring property, or poor original grading — correcting the slope is often simpler and less expensive than installing underground systems. Regrading restores positive drainage away from the foundation, and an assessment determines whether a swale would help direct the flow toward an appropriate outlet.

Combining Surface and Subsurface Approaches

In many cases the best drainage solution combines surface grading with a french drain or catch basin. Surface grading handles the water that's running across the yard; french drains handle the water that's moving through the soil below. Systems get designed to address both components when needed.
