Repair and stabilization of eroded pond slopes, embankments and channels using grading, soil stabilization, vegetation or riprap.
Detention pond erosion repair in Lakeway deals with a problem built into the terrain: thin soil over limestone that sheds water fast instead of absorbing it. Around Rough Hollow, The Hills and Flintrock, the land drops toward Lake Travis in a series of grades steep enough that any bare slope on a detention basin is already working against itself before the first storm of the season hits.
The pattern shows up the same way across these golf-course and lakeside communities. A forebay silts in faster than expected because runoff off limestone carries fine sediment with nowhere to settle upstream. Side slopes go bare where turf never took, then rill and gully after a hard rain. Outlet structures clog with washed-down gravel and leaf litter from the native cedar and oak along the hillside, which slows drawdown and keeps the pond holding water longer than the design intended. Left alone, volunteer trees root into the embankment itself, and their eventual loss opens a new failure point right in the dam face.
Working with Corral Bros on this scope starts with an on-site walk of the actual pond, not a guess from an aerial photo. We look at the slopes, the channel, the outfall and the forebay, then scope the regrading, stabilization and re-vegetation work the basin actually needs and price it plainly. For boards and property managers juggling an HOA budget or a contractor closeout punch list, that means a clear plan tied to what is on the ground in Lakeway, not a generic stormwater checklist.
We're a local, family-built company that treats your Lakeway property like our own, tidy crews, clear pricing, and detention pond erosion repair that holds up to Travis County conditions. Available as a one-time project or part of an ongoing plan.
We schedule a free on-site walk, usually within 48 hours of your call, and get into the basin itself rather than estimating from a plat. We check the slopes, the outfall, the forebay and any channel erosion, take measurements where needed, and put together a written scope and price before any work starts. For HOA boards, this gives you something concrete to bring to a vote.
It depends on slope grade and vegetation cover more than age. A pond with thin turf on a steep limestone-cut slope can show rilling within a couple of seasons, while a well-vegetated basin on gentler grade might go years. Heavy spring rain events are usually the trigger that turns slow bare-slope wear into a repair call, so a yearly walk-through after wet season catches problems early.
We plan access and equipment staging around the property's actual traffic, whether that is a Flintrock walking path, a parking lot serving retail tenants, or a cart path near a fairway. Most detention basins sit at the edge of a property specifically so this kind of work does not have to cross resident parking or active common areas, and we coordinate timing with the board or manager ahead of mobilization.
Thin soil over limestone means water moves fast and carries sediment instead of soaking in, so bare slopes erode quicker here than in deeper-soil parts of the corridor. It also means stabilization has to account for rock close to the surface when regrading, and re-vegetation choices need to hold on a hard, fast-draining slope rather than a typical lawn-grade soil.
Slope length and steepness drive most of the cost, since steeper embankments need more stabilization and matting per square foot. Beyond that, the amount of regrading required, whether riprap is needed at the outfall or channel, how much sediment has to come out of the forebay, and site access all factor in. We lay out these line items during the estimate so there are no surprises once work starts.
