Detention and retention pond construction that controls stormwater and meets site requirements.
Detention ponds across Lakeway do real work most of the year without anyone thinking about them, until a hard rain hits the limestone hillsides above Lake Travis and the water has nowhere slow to go. These basins catch runoff from rooftops, drives and cart paths before it reaches the lake, and in a city built on thin soil over rock, that job gets harder every year a pond goes unchecked.
Thin caliche and limestone mean water moves fast across the surface and collects fast in the basin, which shows up as a forebay packed with silt long before the rest of the pond looks full. We see slow drawdown after storms where an outlet pipe has partly clogged, bare slopes that never held grass through a dry Hill Country summer, and the occasional volunteer oak or cedar rooting into an embankment at Rough Hollow or The Hills, a sign the structure has gone a long time without attention.
Working with Corral Bros on a basin like this starts with a walk of the site, not a sales pitch. We tell you what the pond needs now versus what can wait, whether that is a developer closing out a project at Flintrock or a board that inherited a system nobody's looked at closely in a few years. From there we build or correct the basin to the standard your property engineer has set, and you get a property manager you can call back.
We're a local, family-built company that treats your Lakeway property like our own, tidy crews, clear pricing, and detention ponds that holds up to Travis County conditions. Available as a one-time project or part of an ongoing plan.
A detention pond temporarily holds stormwater runoff and releases it slowly, so a developed site doesn't flood downstream neighbors or overwhelm storm drains. Most Central Texas commercial sites, subdivisions and larger developments are required to have detention as part of their drainage permit.
A detention pond drains down to empty between storms and is dry most of the time, while a retention pond holds a permanent pool of water. We build and maintain both, choosing the right one based on your site's soils, drainage requirements and available space.
We schedule a free on-site visit, usually within 48 hours, and walk the basin with you or your board. We look at the inlet, the forebay, the embankments and the outlet structure, then put together a scope based on what the pond actually needs, not a generic checklist. If your property engineer has drawings or a maintenance plan on file, we work from those.
Most basins here need attention every few years, sooner if a big storm has pushed sediment into the forebay or knocked down slope cover. Associations that inspect after major rain events tend to catch problems while they are still small, cheaper regrading and reseeding rather than a full rebuild of eroded banks or a blocked outlet structure.
We plan access and staging around the parts of the property people actually use, whether that is a cart path near Flintrock, a parking lot at a retail center, or a shared amenity area in a golf-course community. Most detention basins sit at the edge of a development, so equipment stays off main drives and we coordinate timing with your management office before work starts.
Thin soil over limestone sheds water fast, so basins here tend to fill quickly in a downpour and then drain slowly if the outlet or underdrain is partly blocked. We also see bare, eroded slopes on older basins and volunteer trees taking root in embankments, both of which weaken the structure over time and need to be cleared and stabilized.
Size and depth of the basin, how much sediment has built up in the forebay, how badly the slopes have eroded, and whether the outlet or outfall structure needs rebuilding versus just clearing. A pond with established trees on the embankment or a collapsed riprap spillway costs more to correct than one that just needs grading and reseeding.
Both. We handle new basin construction, excavation, grading and shaping, inlet and outlet structures, riprap and spillways, done to the plan set by your project's engineer. We also take on existing basins that have silted in, eroded, or stopped draining the way they were designed to, bringing them back to working condition alongside whatever standard your engineer or association requires.
