Detention and retention pond construction that controls stormwater and meets site requirements.
Detention ponds in Lockhart carry a lot of water off a short list of corridors, from the Historic Square down through Clear Fork and out toward Brock, and most of them were built to handle Caldwell County rainfall landing on blackland clay. That clay does not drain the way sandy soil does. A pond designed on paper for a certain drawdown time can run slower in the ground once the clay compacts, and that shows up fast when a hard rain follows a dry spell.
We see the same handful of problems on Lockhart sites. A forebay that silts in faster than expected because the clay sheds fine sediment instead of letting it settle. Slopes that went bare after the first growing season and are now cutting rills with every storm. Volunteer trees rooted into an embankment because nobody walked it in a year or two. An outlet structure partly blocked by sediment or debris, holding water longer than the plan calls for. None of that is unusual on a county-seat property with historic homes nearby or working acreage behind it, it is just what this ground does if a basin goes unattended.
Working with Corral Bros on a detention pond means we look at the whole system, not just the symptom you called about. We excavate, grade, and shape to the original design or alongside your site engineer, rebuild or clear inlet and outlet structures, and stabilize slopes with riprap, liner, or spillway work so the fix holds through the next wet season. A property manager or board member gets a straight assessment of what the pond needs and what it does not.
We're a local, family-built company that treats your Lockhart property like our own, tidy crews, clear pricing, and detention ponds that holds up to Caldwell County conditions. Available as a one-time project or part of an ongoing plan.
A detention pond temporarily holds stormwater runoff and releases it slowly, so a developed site doesn't flood downstream neighbors or overwhelm storm drains. Most Central Texas commercial sites, subdivisions and larger developments are required to have detention as part of their drainage permit.
A detention pond drains down to empty between storms and is dry most of the time, while a retention pond holds a permanent pool of water. We build and maintain both, choosing the right one based on your site's soils, drainage requirements and available space.
We walk the basin with you, check the inlet and outlet structures, and look at the forebay, slopes, and spillway before we quote anything. On clay sites around the Historic Square or Clear Fork, we probe the pond floor since blackland clay can hide a silt layer under what looks like standing water or a dry crust. Estimates are free and we usually get on-site within 48 hours of your call.
Most basins on blackland clay need attention every few years, but the real trigger is slow drawdown, standing water more than a couple days after rain, or a forebay visibly filling with sediment. If your site engineer's maintenance schedule calls for it, or your association is closing out a new development and taking over a pond from a builder, that is also when to call.
Yes, we sequence excavation and grading to keep drive aisles and parking lots open as much as possible, and we coordinate timing with property management or the board so residents and tenants get notice before equipment moves in. Retail centers and apartment communities in Lockhart stay operational during the work, we just need a staging area for spoil and materials.
Deep blackland clay drains slowly and swells when wet, so outlet structures and slopes have to be built to move water off the clay rather than let it sit and soften the embankment. Lockhart's pattern of long dry stretches followed by hard rain also means bare slopes erode fast once they lose grass cover, which is why slope stabilization matters as much as the excavation itself.
Volume of material to move, how silted the forebay is, and whether outlet structures need to be rebuilt instead of cleaned all affect cost, as does slope length and how much riprap or liner the spillway needs. A pond that has had volunteer trees take root on the embankment usually costs more because root removal has to happen before we can regrade and stabilize.
