Repair and stabilization of eroded pond slopes, embankments and channels using grading, soil stabilization, vegetation or riprap.
Detention pond erosion repair is a recurring need across Buda, where commuter neighborhoods built out fast over the last several years and left a lot of detention basins doing the job of catching runoff before it ever had a chance to settle in. These ponds were engineered to hold water temporarily and release it slowly, but the slopes, forebays, and outlet structures around them take the actual beating, storm after storm.
Buda sits on rocky clay with a shallow caliche layer that does not drain the way deeper soils do, so water tends to concentrate and move fast instead of soaking in evenly. That shows up in specific ways: a forebay silted in from the last few heavy rains, a drawdown that takes noticeably longer than it used to, bare clay slopes where turf never fully took hold, or a volunteer tree rooted into an embankment it should not be anywhere near. A blocked or partially buried outlet is common too, especially on ponds that have gone a few seasons without attention.
Working with Corral Bros on this scope starts with a walk of the basin, not a guess from a satellite photo. We tell you what we see, what is driving the erosion, and what order of operations gets it stable, whether that means regrading a slope, repairing a channel, placing riprap at an outfall, or seeding and matting a bare embankment. For HOA boards, association managers, and property managers who are accountable for that pond at the next inspection or the next annual meeting, that means a clear plan instead of a mystery line item.
We're a local, family-built company that treats your Buda property like our own, tidy crews, clear pricing, and detention pond erosion repair that holds up to Hays 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 full basin with whoever manages the property, whether that is a board member, an association manager, or an onsite facility manager. We look at the embankment slopes, the forebay, the outlet structure, and any channel feeding or leaving the pond. You get a straightforward rundown of what is causing the erosion and what it will take to fix it, no pressure to decide on the spot.
It depends on the age of the development and how much bare slope was left after construction, but many Buda basins need some attention every few years, especially in the first five years after a neighborhood is built out. Newer sections of Sunfield and Whispering Hollow tend to show slope erosion earlier because vegetation has not fully established yet on the caliche subsoil. A heavy spring storm season can accelerate the timeline regardless of age.
We stage equipment and materials inside the detention easement itself whenever the layout allows, which keeps crews off drive aisles and resident parking. For HOA-maintained ponds near Garlic Creek or Whispering Hollow, we coordinate timing with the board or association manager so mowing contractors and irrigation techs are not caught off guard. On commercial sites, we plan access around tenant deliveries and peak traffic hours rather than working on our schedule alone.
Buda's rocky clay with shallow caliche does not absorb water quickly, so basins here tend to show concentrated flow paths and channel scour rather than even sheet erosion across a slope. When a hard rain follows a dry stretch, water moves fast over ground that barely lets it soak in, and that is usually what undercuts an outfall or carves a gully down an embankment. Any regrading or re-vegetation work has to account for that shallow caliche layer, not just the surface soil.
The biggest factors are how much regrading is needed, whether riprap or erosion matting is required at the outfall, and how much of the slope needs reseeding versus full stabilization. Access also matters. A pond tucked behind a retail center with a narrow easement costs more to work in than an open HOA basin with a service road. We price each job after the site walk rather than quoting blind over the phone.
