Repair and stabilization of eroded pond slopes, embankments and channels using grading, soil stabilization, vegetation or riprap.
Detention pond erosion repair in West Lake Hills has one recurring cause: steep canyon lots cut into Austin limestone do not give rainwater anywhere to go but down, fast. These basins were built to catch runoff from high-end wooded estates and the roads that serve them, and the same grade that makes the views good is what tears up a pond slope during a hard rain.
On the ground that looks like a few familiar problems. A forebay silted in from soil washed off a bare upper slope. An outlet structure partly blocked by leaf litter and sediment, so drawdown after a storm takes longer than it should. Volunteer cedar and hackberry taking root on an embankment where nobody has mowed or maintained ground cover in a few seasons. Channel bottoms scoured down to rock where water concentrates coming off Rollingwood and Davenport Ranch's steeper streets. None of it is unusual for this terrain, but none of it fixes itself either.
Working with Corral Bros on this scope starts with a site walk, usually within 48 hours of your call, where we look at the whole basin and tell you plainly what we see. We scope the regrading, stabilization, riprap or re-vegetation the slope actually needs, put it in writing, and schedule the work around your tenants, residents or ongoing construction. You get a stable basin and a straight answer about what it took to get there.
We're a local, family-built company that treats your West Lake Hills 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 walk the full basin with whoever manages the property, from the inlet down to the outfall, and look at the embankment, the forebay and the spillway. On steep Davenport Ranch or Eanes sites we also check how the slope ties into the surrounding limestone grade. The walk is free with no obligation, and we usually get out there within 48 hours of your call.
There is no fixed schedule, it depends on slope and storm exposure, but most ponds on these steep, wooded lots need some grading or re-vegetation work every few years. A pond cut into a canyon lot with thin soil over limestone sheds water fast, so a couple of heavy storm seasons can undercut a slope that looked fine the year before. We size the interval to what we see on your embankment, not a calendar.
Yes, we schedule grading, matting and planting work around your property's traffic and parking needs and stage equipment to keep drive aisles and resident or tenant parking open. For HOA and POA common areas we coordinate timing with the board or manager first. Most pond work does not require closing units or storefronts, just keeping foot traffic off wet slopes while seed and matting take hold.
Thin soil over Austin limestone does not absorb water the way deeper soil does, so runoff off these canyon lots moves fast and concentrates in narrow channels. That shows up as scoured channel bottoms, a silted forebay, or a slope that has gone bare because topsoil washed off before grass could hold it. We match the stabilization method, riprap, matting or regrading, to how much velocity that particular slope is actually seeing.
Slope steepness, access for equipment on a wooded canyon lot, and how much of the embankment or channel is affected all factor in. A single eroded outfall is a different job than a full slope regrade with riprap and re-vegetation. We walk the site, scope exactly what needs doing, and put it in writing before any work starts, so you are not guessing.
