Excavation and removal of built-up sediment to restore a detention pond's designed storage, drainage performance and access.
If you manage a detention pond in Cedar Park, you have probably already seen what shallow rocky soil does to a basin's storage capacity over time. Between Buttercup Creek, Cypress Mill, and the Ranch at Brushy Creek, most of these ponds were built to handle Hill Country runoff moving fast off caliche and limestone, and they fill with sediment faster than the design drawings assumed. Corral Bros handles the excavation, grading, and hauling to get that storage back.
Limestone sits close to the surface across most of Cedar Park, which means water does not always soak in the way a pond's outlet structure expects. Drawdown slows down, fine sediment drops out in the forebay before it ever reaches the main pool, and the outlet pipe ends up half buried in silt nobody has looked at since the final inspection. Give it a few seasons and you will also find volunteer cedar and hackberry taking root on the embankment, roots that work into the same rock that is already fighting your drainage. None of that shows up from the parking lot. It shows up when you walk the slope or check the pond after a hard rain.
Working with us starts with a site walk, not a sales pitch. We check sediment depth, look at the forebay and outlet, and tell you what we actually found, not a padded list of upsells. If the pond ties back to an engineer of record, we do the excavation and grading to that plan rather than guessing at design elevations. You get a crew that shows up when scheduled, hauls what it digs, and leaves the basin at the grade it was built to hold.
We're a local, family-built company that treats your Cedar Park property like our own, tidy crews, clear pricing, and detention pond sediment removal that holds up to Williamson 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 basin with you or your maintenance lead. We check sediment depth at the forebay and main pool, look at the outlet structure, and note any grading or slope issues. You get a straightforward scope and a price before anything is scheduled, no obligation to move forward.
Most Cedar Park basins need a real cleanout somewhere between five and ten years after construction, sooner if the drainage area above the pond was built out recently or if you have noticed water sitting longer after storms. Ponds serving older sections of Ranch at Brushy Creek tend to show a silted-in forebay well before the main pool loses much capacity.
We stage equipment and haul routes to keep the work contained to the pond footprint and existing access easements wherever possible. For HOA common areas and retail centers, we coordinate timing with your board or property manager so mowing crews, trash pickup, and resident traffic are not caught off guard. Fencing around open excavation stays up until grading is finished.
Shallow soil over limestone changes how a pond drains and how it silts up. Water that should move through the outlet in a day or two can sit for a week when the bedrock sits close to the design grade, and that slower drawdown lets fine sediment settle out right where you do not want it, in the forebay and around the outlet structure. We account for that rock when we restore grade so the pond drains the way it was designed to.
Volume of sediment is the biggest factor, since that drives excavation time and the number of truckloads hauled offsite. Access matters too: a pond with a clear equipment path costs less to work than one boxed in by fencing, mature trees, or a single narrow easement. Outlet condition, embankment growth that needs clearing first, and disposal distance also move the number.
