Cleaning, mowing, grading, vegetation control, debris removal and erosion repair for drainage swales, channels, ditches and culverts.

Walk the swales behind Bentwood Ranch or Falcon Ridge after a few years of growth and you will usually find the same thing: grass gone to seed and matting down the flow line, a culvert mouth half packed with silt, and a low spot that holds water two days after everything else has dried out. That is what swale, channel and culvert maintenance in Cibolo actually looks like on the ground, before anyone calls it a system.
Cibolo sits on clay that swells when it is wet and cracks hard when it dries, and that movement reshapes drainage lines faster than most boards expect. A swale graded flat three years ago settles unevenly over expansive clay and starts holding water instead of shedding it. In newer sections like Buffalo Crossing, young trees and shrubs planted close to channels send roots into the banks, and volunteer saplings take hold on embankments nobody is mowing close enough to catch. Add a hard Hill Country downpour on ground that has not fully stabilized yet, and silt loads up fast in forebays and culvert inlets.
Working with Corral Bros on this scope starts with a walk of the actual swales, channels and culverts on your property, not a guess from a plan set. We clean and clear what has choked up, mow and manage vegetation along the banks, regrade where water is pooling or cutting, and repair erosion before it undercuts a slope or a culvert end. If your site has a property engineer on record, we work alongside their plan rather than redesigning anything ourselves.
We're a local, family-built company that treats your Cibolo property like our own, tidy crews, clear pricing, and swale, channel & culvert maintenance that holds up to Guadalupe County conditions. Available as a one-time project or part of an ongoing plan.
We schedule a free, no-obligation site walk, usually within 48 hours of your call, and look at every swale, channel and culvert on the property rather than quoting from a site plan. You get a price based on what is actually silted, overgrown, or eroding, not a flat per-foot number.
Most HOAs here are on a mowing and vegetation cycle through the growing season, with a fuller cleaning and culvert check once or twice a year. Properties with young landscaping or recent grading often need an extra pass the first couple of years, since the clay has not finished settling and bare slopes erode faster.
Expansive clay shifts with moisture, so a swale that drained fine at construction can develop low spots or reversed grade within a few seasons. We regrade to restore proper fall rather than just clearing vegetation, because mowing alone will not fix a channel that has stopped moving water.
Yes. Most of this work happens along common-area easements and detention features, away from units and parking areas, and we schedule mowing and heavier equipment work to minimize disruption. If access requires coordination with a gate code, leasing office, or HOA notice, we work around that timeline.
The biggest factors are how much silt has built up in channels and culvert inlets, how overgrown the vegetation is, how many erosion spots need regrading or repair, and how many culvert crossings are on the property. A newer section with young, lightly established landscaping is usually a faster job than an older channel that has gone a few seasons without attention.
