Detention and retention pond construction that controls stormwater and meets site requirements.
If you manage a property in Austin, your detention pond is your responsibility the moment the city or your site plan says water has to leave that basin at a controlled rate. That means the forebay, the outlet structure, the slopes, and the spillway are on you, whether the pond sits behind a Mueller apartment complex, a Circle C retail pad, or a tech campus off the MoPac corridor.
Austin's ground does not treat every basin the same way. East of MoPac, black gumbo clay swells and cracks and can slow a pond's drawdown to a crawl after a hard rain. West of MoPac, thin soil over limestone means roots and erosion expose rock fast, and volunteer trees seed themselves into embankments if nobody is pulling them. A silted-in forebay, a blocked outlet pipe, bare slopes losing ground every storm, these are the things we find on Austin sites, not hypotheticals.
Working with Corral Bros on a detention pond means a site walk where we tell you what we see in plain terms, a scope that matches your plan or your property engineer's requirements, and a crew that handles grading, structures, and stabilization as one job instead of three separate calls. We are licensed, insured, and locally owned, and we build and repair basins across the Austin area from Tarrytown to Zilker to the Hill Country edge.
We're a local, family-built company that treats your Austin 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 walk the basin with you, check the forebay, outlet structure, and embankments, and note what is actually holding water versus draining the way the plan intended. Estimates are free and usually scheduled within 48 hours. You get a straight read on what is maintenance and what is repair before any work starts.
Most basins need a real look at least once a year, but Austin's heavy spring and fall downpours after dry stretches move a lot of sediment fast, so a pond that looked fine in January can have a silted-in forebox by June. Boards usually catch problems during a routine walk or after a city inspection flags something.
We schedule around your property's traffic, whether that is a Circle C retail lot during business hours or a Mueller apartment complex with resident parking tight to the basin. Access and staging get worked out with you before equipment shows up, so there are no surprises for tenants or residents.
Yes. Black gumbo clay east of MoPac holds water and shrinks and cracks as it dries, which stresses slopes and liners differently than the limestone shelf to the west, where shallow rock can turn grading into real excavation. We read the site's soil before we quote the scope, not after.
Basin size and depth, how much sediment has built up in the forebay, whether slopes need riprap or just reseeding, and whether outlet or outfall structures need rebuilding versus clearing all move the number. A pond with a cracked spillway costs more to fix than one that just needs grading and erosion control.
