Inspection, cleaning and maintenance of stormwater best management practices, from ponds and swales to filters and underground structures.
Hill Country downpours do not ease into Leander, they arrive heavy and fast, then stop, leaving a short window to see how a stormwater system actually performs. That is usually when somebody responsible for a pond, swale or underground structure in Leander, Texas calls Corral Bros about stormwater BMP maintenance.
The ground here is the other half of the problem. Thin soil over limestone sheds water quickly instead of soaking it in, so runoff hits basins hard and carries clay and rock fines with it. We see forebays silted in within a year of a neighborhood opening, outlet structures packed with debris, slow drawdown after storms, and bare or eroding embankments where grass never got established. In newer sections of Crystal Falls, Travisso and Bryson, volunteer trees and weeds on a slope are often the first sign nobody has walked the pond since the builder left.
Working with us starts with that walk. We look at sediment depth, vegetation, outlet condition and drawdown before we write a scope, so you are not paying for guesswork. From there we handle the cleaning, structure upkeep and drainage checks your board, your HOA or your closeout paperwork needs, and we keep documentation ready for the compliance conversation when it comes up.
We're a local, family-built company that treats your Leander property like our own, tidy crews, clear pricing, and stormwater bmp maintenance that holds up to Williamson County conditions. Available as a one-time project or part of an ongoing plan.
We schedule a free on-site visit, usually within 48 hours of your call, and walk the pond, swale or structure with whoever manages the property. We check the forebay, outlet structure and side slopes, note sediment depth and any blocked drainage, and give you a scope before any work starts. If your site has a civil engineer of record, we are glad to work alongside their plan rather than guess at it.
It depends on age and how much upstream construction is still happening. A basin serving a subdivision still building out can silt in within a season or two, while an established pond in an older section might only need attention once a year. We look at drawdown time, sediment buildup and vegetation on the slopes to tell you where your specific pond stands, not a generic schedule.
Shallow soil over limestone does not absorb water quickly, so runoff concentrates fast during Hill Country downpours and carries clay and rock fines straight into the forebay. That sediment settles out and chokes drawdown long before the rest of the basin looks full. We clear that forebay and check the outlet structure so the pond keeps draining at the rate it was built for, instead of holding water for days after a storm.
Yes. Most ponds and underground structures sit away from building entrances, so we coordinate access and timing with your property manager or HOA board to avoid blocking parking or disrupting tenants. For sites still under construction, like phases in Bryson or Travisso, we also work around active grading and utility crews on the schedule you or the general contractor set.
Sediment volume in the forebay is usually the biggest factor, along with how much vegetation has taken hold on the slopes or embankment since the last cleaning. Access matters too: a pond you can reach with equipment costs less to maintain than one boxed in by fencing, retaining walls or finished landscaping. Underground structures and separators add cost depending on depth and how much standing debris has built up inside.
