Underground detention and stormwater control measures (SCMs) for tight sites, parking lots and developments.
Subsurface stormwater control measures around Lago Vista carry a load that most inland developments do not plan for: runoff coming straight off rocky, thin-soil slopes into Lake Travis. Chambers, vaults, and underground pipe systems serving sites in Highland Lake Estates, Bar-K Ranches, and Point Venture end up doing double duty, controlling volume and keeping sediment and debris out of the lake itself. When one of these systems is undersized, clogged, or was never fully commissioned by the original developer, the property's board or manager is usually the one who finds out first.
The ground here does not absorb water the way a flatter clay-based site would. Thin soil over limestone means runoff moves fast and carries grit, so forebays silt in sooner than the design drawings assumed, and outlet structures catch leaves and gravel washed off bare embankments. On older hillside lots we also find volunteer trees rooted into berms and slopes that were supposed to stay clear, slow drawdown after storms, and pipe runs that were backfilled against rock rather than graded soil, which changes how they settle and drain over time.
Working with Corral Bros on this scope starts with a free on-site look at the actual structure, not just a review of old plans, since what is buried on a Lago Vista lot does not always match the paperwork. We handle inspection, cleaning, jetting, and retrofits for chambers, vaults, and pipe systems, and where the fix involves more than maintenance we coordinate with your property engineer rather than redesigning anything ourselves. Call (737) 404-9343 and we will get someone out, usually within 48 hours.
We're a local, family-built company that treats your Lago Vista property like our own, tidy crews, clear pricing, and subsurface stormwater control measures that holds up to Travis County conditions. Available as a one-time project or part of an ongoing plan.
A subsurface stormwater control measure is used when there isn't room for a surface pond, tight commercial lots, parking areas and dense developments. The system goes underground (chambers, vaults or pipe galleries) and stores or infiltrates stormwater beneath the site, freeing up the surface for parking or building.
Yes. Subsurface SCMs accumulate sediment and debris and must be inspected, cleaned and jetted on a schedule to keep working and stay compliant. We service, clean and retrofit underground detention and infiltration systems throughout Central Texas.
We schedule a free on-site visit, usually within 48 hours, and open or locate the chamber, vault, or pipe network to see what we are dealing with before quoting anything. On rocky Lake Travis lots that often means pulling a grate or lid near the forebay first, since paper records and as-builts do not always match what was actually installed on these hillside sites.
Slow drawdown after a storm, standing water in a vault days later, or a note from an association's engineer during a routine compliance check are the usual triggers. Developments around Highland Lake Estates and Bar-K Ranches built in stages over the years often need a first real inspection once an HOA takes the system over from the original developer.
It depends on the site, but thin soil and rocky runoff around Lago Vista tend to push sediment into chambers and pipes faster than flatter, sandier ground does. An annual inspection with cleaning or jetting as needed is a reasonable baseline, and we can set a schedule that lines up with whatever your governing documents or property engineer already require.
Most subsurface work happens at grade level, lids, risers, and inlet structures, so we stage around active parking stalls and leasing traffic rather than shutting a lot down. For gated communities near Point Venture we coordinate access ahead of time so residents and your front office are not caught off guard by equipment on site.
Thin soil over rock on these lakeside slopes means infiltration systems do not always drain the way the original design assumed, and heavy pipe or chamber runs sometimes hit rock sooner than plans show. We dig or probe before we commit to a repair approach, and where the system needs redesign we work alongside the property's engineer rather than guessing.
Access and depth matter most, how far the chambers or vaults sit below grade and whether equipment can reach the structure without tearing up pavement or landscaping. Sediment load, pipe length, and whether we are cleaning an existing system versus retrofitting one that was undersized for the site also factor in. We price after the site walk, not before.
