Excavation and removal of built-up sediment to restore a detention pond's designed storage, drainage performance and access.

Detention ponds around Elgin earn their keep during Hill Country downpours, but every storm that fills one also drops sediment that never leaves on its own. Between Elgin Acres, the Highway 290 corridor and the lots around Downtown Elgin, we see basins that were built to hold a certain volume now holding noticeably less, because nobody has excavated the muck that settled into the forebay and the main pool. Sediment removal restores that lost storage and gets the pond draining the way it was designed to.
The pattern here comes straight from the ground. Elgin's sandy loam gives way to blackland clay not far down, and that clay sheds fine sediment hard once a heavy rain gets moving across rooftops and pavement. We find forebays silted in tight, slow drawdown that leaves standing water for days after a storm, bare or slumping slopes where grass never took, and more than once a volunteer tree rooted into an embankment because enough sediment built up to give it something to grow in. A blocked or buried outlet structure is usually part of the story too.
Working with Corral Bros on this scope starts with a straightforward site walk, not a sales pitch. We check sediment depth, look at the outlet and forebay, and tell you plainly what has to come out and what it will take to get equipment to it. From there we excavate, clean out the outlet and forebay, restore the design grade, and haul the material off site, whether you are an HOA board managing a shared amenity, a property manager running a retail center, or a GC closing out a development for handover.
We're a local, family-built company that treats your Elgin property like our own, tidy crews, clear pricing, and detention pond sediment removal that holds up to Bastrop 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 whoever manages the property, whether that is an HOA board member, a community association manager or a general contractor closing out a site. We check sediment depth at the forebay, the main pool, and the outlet structure, and we look at slope condition and access for equipment. You get a clear scope before anything is scheduled.
It depends on the drainage area and the ground upstream, but many Elgin basins need attention every few years rather than every decade. Properties near the 290 corridor with larger paved catchments tend to silt in faster than older Downtown Elgin lots, and a pond that used to drain overnight but now holds water for two or three days is usually telling you sediment has built up at the outlet or forebay.
We plan haul routes and staging around your property's actual traffic, not the other way around. For retail centers and apartment communities we coordinate timing with property management to keep drive aisles and resident parking open, and for HOA common areas we can phase the excavation so the pond is never fully blocked off longer than necessary.
Elgin sits where sandy loam gives way to blackland clay, and that clay holds water and sheds fine sediment hard during heavy rain. Basins here commonly show a silted-in forebay, bare or slumping slopes, and sometimes volunteer trees taking root on the embankment where sediment has built up enough to support them. We account for that mixed soil when we excavate and restore grade.
The main factors are how much sediment has to come out, how far equipment has to travel inside the property to reach the pond, and how far the material has to be hauled for disposal. A pond with a collapsed outlet or trees established on the embankment takes more time than a straightforward muck-out, and tight access on an older Downtown Elgin lot can add to the job as well.
