A flat city on caliche, dotted with playa basins — the clearest case of why South Plains yards flood, and how we drain them.
Tell us what your yard is doing and we’ll come take a look — no charge.
Lubbock is where we’re based, and it’s the clearest case study of the whole South Plains drainage story — a flat city built on caliche, dotted with playa basins the city itself turned into stormwater parks.
Under most of the city, a caliche hardpan sits two to three feet down, and the Handbook of Texas describes that caprock as impervious — water can’t soak through it. The ground is nearly flat, so there’s no natural slope to carry water off, and the land drains internally toward local low spots. Lubbock is so defined by its playas that many of them — the chain of lake parks across the city — function as stormwater basins. If your lot sits low, near one of those basins, or simply on ground the caliche won’t drain, it floods in a hard storm and then holds the water.
Older central neighborhoods often have grades scrambled by decades of settling, added drives, and mature trees, so water finds low spots the builder never intended. The newer subdivisions ringing the city — south and west especially — are cut flat on caliche, and the backyards have nowhere to shed water. Both come down to the same fix: give the water an engineered path off the lot, because the ground won’t take it and the land won’t carry it.
Whatever the yard is doing, we bring the full range to Lubbock — and it all starts with understanding why yards here flood:
There’s a peculiar rhythm to a Lubbock yard: under the city’s watering restrictions the lawn runs dry and dusty for stretches, and then a single May thunderstorm dumps two inches on ground that can’t absorb it and the backyard becomes a pond. That swing between bone-dry and flooded is the local normal, and it’s hard on both lawns and slab foundations. Drainage that carries the storm water off quickly is half of managing it; the other half is grading that keeps what does fall from pooling against the house.
Lubbock only averages about 18.33 inches of rain a year, but roughly two-thirds of it falls in hard May-through-September thunderstorms. A flat caliche lot can’t absorb or shed a two-inch downpour, so it floods even in a dry climate. We build for that storm, not the gentle average.

What Lubbock homeowners ask when a drain has stopped moving water.
Drain clearing is the other half of drainage work in Lubbock. A drain that was built correctly still fills with the fine, wind-blown soil that sits over our caliche, and a flat lot gives it very little fall to flush itself. When a line stops moving water, the question is always whether it is blocked or broken — and those are two different jobs.
Yes — drain clearing is part of drainage repair. That covers French drain lines that have silted up, buried downspout and yard drain lines that have blocked, and catch basins that have filled with sediment. Clearing is the first step; whether the line then needs repair or replacement depends on what the blockage turns out to be.
Two local reasons. Caliche and the fine, wind-blown soil above it produce a lot of fine particles, and those fines migrate into gravel and pipe over time. And a flat lot gives a drain very little fall, so water moves slowly and drops its sediment inside the pipe rather than carrying it out. A drain built without filter fabric or a pipe sock will silt shut fastest of all.
Clearing removes what is blocking a line that is otherwise intact — sediment, roots, debris. Repair is needed when the line itself has failed: crushed pipe, a collapsed section, a disconnected joint, or an outlet that was never built to daylight properly. A camera or a dig at the outlet usually settles which one you have.
The tell is water standing over the grate, or backing up out of it, when the rain is light. A drain that only struggles in a genuine downpour may simply be undersized for the volume. A drain that ponds in an ordinary shower, or that drains far more slowly than it did last year, is blocked.
It can contribute. A blocked line holds water against the house instead of carrying it away, and around Lubbock the concern is the wet-dry swing in the soil at the perimeter rather than the water itself. Keeping the perimeter moisture steady is the reason foundation drainage exists, and a blocked drain works against exactly that.
Yes. Buried downspout lines are one of the most common blockages we find, usually from leaf and grit build-up at a low point or at the outlet where a pop-up emitter has been driven over or buried by turf.
There is no fixed interval — it depends on the soil, the fall, and whether the drain was built with filter fabric. A practical rule for a Lubbock lot is to check the outlet twice a year, before the spring storms and after the autumn leaf drop, and to look at the drain properly whenever water starts standing longer than it used to.
