Excavation and removal of built-up sediment to restore a detention pond's designed storage, drainage performance and access.
Blackland clay does not filter anything on the way into a pond, it washes in as fine particle sediment that settles slow and packs hard once it dries. In Manor, that means detention pond sediment removal is a recurring line item for any property built on the eastern prairie, not a one-time fix.
ShadowGlen, Whisper Valley and Stonewater all share the same story: new subdivisions, recently graded lots, and heavy summer downpours that hit bare dirt before the grass has a chance to hold it. That runoff carries straight into the nearest basin. The signs show up the same way almost every time: a pond that takes an extra day or two to draw down after a storm, a forebay silted in and holding standing water, volunteer willows or hackberry starting up on the embankment, or an outlet structure half buried and barely moving water. On new construction sites still under a performance bond, this is often the first stormwater problem a developer or GC has to deal with before handoff.
Working with Corral Bros on this scope starts with a site walk and a sediment depth check so you know what you are dealing with before any excavation begins. We dig to the design grade, clean out the forebay and outlet, and haul the spoil offsite so the basin is back to doing the job it was built for. If the pond falls under an engineer's plan, we do the excavation and grading to match that plan rather than guessing at it ourselves.
We're a local, family-built company that treats your Manor 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 schedule a free, no-obligation site visit, usually within 48 hours of your call, and walk the basin with you or your maintenance contact. We check sediment depth at several points, look at the forebay and outlet condition, and note any slope or access issues before putting together a scope and estimate.
It depends on the age of the development and how much bare or recently graded ground drains into it. New subdivisions like ShadowGlen or Whisper Valley often need their first cleanout within a few years of construction because exposed soil washes in fast. Once turf is established upstream, the interval usually stretches out, but a slow drawdown after storms is the signal to call.
Yes. Most basin excavation happens away from units and common parking, and we coordinate access routes and equipment staging with the property manager or HOA ahead of time. If haul trucks need to cross a drive aisle or use a specific gate, we work that into the schedule so daily traffic is not disrupted.
Blackland clay sheds fine sediment fast during heavy rain and then dries into a dense, compacted layer that does not break up on its own. That combination is why forebays in Manor silt in quicker than in sandier soils, and why outlet structures get buried if a pond is not checked regularly, especially on newer sites where upstream ground is still exposed.
The main factors are how much sediment has built up, how far equipment has to travel within the site, access and slope conditions around the basin, and how far the spoil has to be hauled offsite. A pond with a badly silted forebay or a buried outlet structure takes more time than routine maintenance, which affects the cost.
