Excavation and removal of built-up sediment to restore a detention pond's designed storage, drainage performance and access.
Detention pond sediment removal in Cibolo is a recurring need for the newer subdivisions filling in around Guadalupe County, where ponds built just a few years ago are already losing storage capacity to silt. Properties in Bentwood Ranch, Falcon Ridge, and Buffalo Crossing were graded and seeded on a construction schedule, and the pond was often the last thing finished before the builder moved on. Once homes and lots are occupied, that pond quietly keeps doing the job it was designed for, until sediment catches up with it.
Cibolo sits on expansive clay that moves with moisture and sheds runoff hard once it is saturated. In a young subdivision, slopes and swales that have not fully grassed over send loose soil straight into the basin with every heavy rain. The result shows up in predictable ways: a forebay packed with silt, water drawing down slower than it used to after a storm, bare or eroding embankments, and sometimes volunteer trees or brush rooting in sediment near the outlet structure where nobody notices until it is blocking flow.
Working with Corral Bros on this scope starts with a straightforward look at what is actually in the pond, not a sales pitch. We check sediment depth against the design grade, confirm what the outlet and forebay need, and give the property manager or board a clear picture of the work before equipment arrives. From there it is excavation, grading back to design, and hauling the material offsite so the pond functions the way the engineer intended.
We're a local, family-built company that treats your Cibolo property like our own, tidy crews, clear pricing, and detention pond sediment removal that holds up to Guadalupe County conditions. Available as a one-time project or part of an ongoing plan.
We schedule a free on-site visit, usually within 48 hours of your call, and walk the pond with whoever manages the property, often an HOA board member or community association manager. We check sediment depth against the original grade, look at the forebay and outlet structure, and give you a straightforward estimate before any equipment shows up.
It depends on how much of the drainage area upstream is still bare dirt or newly seeded, since that raw ground washes into the pond fast in the first few years after construction. Many newer Cibolo subdivisions need their first real sediment removal within a few years of buildout, and after that it is usually tied to how the pond is drawing down, not a fixed calendar.
We stage equipment and haul trucks to keep access roads and parking lots open as much as the site allows, and we coordinate timing with your board or property manager ahead of the work. Most detention ponds sit apart from the buildings and lots people use daily, so the disruption is usually limited to noise and truck traffic near the pond itself for the duration of the excavation.
The expansive clay common around Cibolo sheds water fast once it is saturated, so heavy rain carries loose soil and construction fines straight into the pond, especially from embankments and slopes that have not fully grassed over yet. That shows up as a silted forebay, slower drawdown after storms, and sometimes volunteer trees or brush taking root in sediment near the outlet.
The biggest factors are how much sediment has built up, how far the muck has to travel to reach a haul truck, and whether the outlet structure or forebay needs extra attention beyond a standard cleanout. Access matters too, since a pond that trucks can reach directly costs less to clear than one tucked behind tight turns or soft ground. We spell out the specifics after the site walk, not before.
