Excavation and removal of built-up sediment to restore a detention pond's designed storage, drainage performance and access.
Detention pond sediment removal in Universal City comes up again and again for the same reason: this city sits on thin clay over bedrock near Randolph AFB, and that ground does not absorb water the way looser soil does. Basins here are doing most of the work themselves, which means any buildup of sediment in the storage area or forebay cuts into capacity fast. A pond that was engineered to hold a certain volume starts falling short the moment silt eats into that space, and the people who find out first are the ones managing the property.
Walk a basin in Forest Crest, Northview, or Olympia Hills after a few years of service and the pattern tends to look the same. Drawdown that used to take a day now takes three. The forebay, which should be acting as the first catch for grit and debris, has silted down to a shallow puddle or gone dry entirely. Embankment slopes that were graded clean at construction now have volunteer trees or brush rooting into them, and somewhere near the outlet there is a mat of leaves, sediment, or trash narrowing the flow more than anyone realized until the next hard rain backs the whole system up.
Working with Corral Bros on this scope starts with a site visit, not a sales pitch. We check sediment depth, look at the outlet and forebay condition, and tell you what we find in plain terms. From there we excavate and haul the muck offsite, restore the pond to its design grade, and clean out the forebay and outlet so the system drains the way it was built to. Whether you are an HOA board, a property manager, or a GC closing out a site near Randolph, you get a crew that has done this work on basins like yours before.
We're a local, family-built company that treats your Universal City property like our own, tidy crews, clear pricing, and detention pond sediment removal that holds up to Bexar 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, and walk the basin with whoever manages the property, whether that is a board member, a community association manager, or an onsite facility contact. We check sediment depth at the forebay and main pool, look at the outlet structure, and note slope condition. You get a straightforward scope and a number before any equipment shows up, no obligation to move forward.
It depends on the drainage area and how much bare or disturbed ground feeds into it, but established basins in older sections like Forest Crest or Northview often need attention every several years, sometimes sooner if a forebay silts in fast. The real trigger is performance, not a calendar: slow drawdown after storms, standing water days later, or a forebay that has gone from a pool to a mudflat are signs it is time to call.
We stage equipment to use the smallest footprint possible and coordinate timing with property management so hauling trucks are not blocking resident parking or retail customer access during peak hours. For HOA-maintained ponds near Olympia Hills or similar neighborhoods, we talk through access points and any shared drives ahead of time so residents are not surprised by equipment on a given morning.
The thin clay over bedrock common near Randolph AFB does not let water percolate the way sandier soil does, so basins here rely heavily on their designed storage and a clear outlet to drain on schedule. When that clay silts in or an outlet gets choked with debris, drawdown slows fast, and heavy spring and fall rain events expose the problem quickly rather than gradually.
Access for hauling equipment, total sediment volume, how far the muck has to travel to get offsite, and the condition of the outlet and forebay structures all factor in. A pond with a short, clear haul route and moderate silt costs less to clear than one with tight access, overgrown embankments, or a forebay that has been neglected for years. We price it after the site walk, not before.
