Excavation and removal of built-up sediment to restore a detention pond's designed storage, drainage performance and access.
Detention ponds across Bee Cave take on more sediment than their original design accounted for, mostly because the watersheds feeding them sit on thin soil over limestone. When a hard rain hits exposed caliche or a freshly graded lot upstream, the runoff carries fine sediment straight into the basin instead of letting it settle out gradually. Corral Bros handles detention pond sediment removal for properties throughout Bee Cave, from Lake Pointe to Falconhead to Spanish Oaks, restoring the storage volume and drainage performance the pond was built to provide.
On these rocky benches and steep Hill Country grades, the signs show up in predictable places. A forebay that used to catch the coarse sediment is silted level with the pipe invert. Drawdown that should take a day now takes three or four after a storm. Volunteer trees and brush have rooted into an embankment that was supposed to stay clear for inspection and mowing. An outlet structure is half buried and nobody noticed until the pond started holding water it was never meant to hold. These are not cosmetic issues. They are capacity problems building toward the next big rain event.
Working with us starts with a site walk and a sediment depth check against the pond's design grade, so you know what you are dealing with before a crew shows up. We excavate to restore that grade, clean out the forebay and outlet, and haul the material offsite. Whether you are a property manager closing out a punch list, an HOA board handling deferred maintenance, or a GC turning a site over to an association, you get a straightforward scope and a pond that works the way it was engineered to.
We're a local, family-built company that treats your Bee Cave property like our own, tidy crews, clear pricing, and detention pond sediment removal that holds up to Travis County conditions. Available as a one-time project or part of an ongoing plan.
We walk the pond with you or your engineer, probe the forebay and main basin to check sediment depth against the original design grade, and look at the outlet structure for blockage. Most estimates in Bee Cave are scheduled within 48 hours of your call. You get a clear scope before anything is excavated, no guessing on the back end.
It depends on the watershed above it, but on Hill Country sites with exposed caliche and new construction nearby, we see forebays needing attention every two to four years. A pond that used to drain down within a day or two after a storm and now holds water for three or four is telling you sediment has built up and it is time to check it.
Rocky benches mean we often hit refusal above the original dig depth, so we confirm grade with probes rather than assuming the whole basin needs the same cut. Steep side slopes around Lake Pointe and Spanish Oaks also mean erosion control and equipment access get planned before excavation starts, not after.
We stage equipment and haul routes to keep traffic lanes and resident parking open, and we coordinate timing with property management or the HOA board ahead of mobilization. On retail and apartment sites around the 71/620 corridor we typically work in sections so the whole lot is never closed at once.
Sediment depth and total volume to haul are the biggest factors, followed by access, since a pond with a tight gated entrance or a steep embankment takes longer to work safely than one with open equipment access. Outlet and forebay condition also matter. A clogged outlet structure adds time beyond straight excavation.
