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.
