Vegetation clearing, debris removal, grading and erosion correction that keep a detention pond's emergency spillway clear and functional.
If your detention pond's emergency spillway is choked with willows, silt, or a beaver dam when the county or your engineer asks about it, that liability sits with the property, not with whoever built the basin. Corral Bros handles emergency spillway maintenance for commercial sites, HOAs, and active-adult communities across San Marcos, from Blanco Gardens to Willow Creek to Kissing Tree.
San Marcos sits on spring-fed river water and thin upland soils over limestone, and both show up in a basin fast. Shallow soil sheds rain quickly instead of absorbing it, so spillways here take harder, faster flows than you'd expect for the rainfall totals. We regularly find a silted forebay choking flow before it reaches the spillway, bare clay slopes sliding after a gully-washer, or a stand of volunteer hackberry and willow rooted into the embankment itself, each one enough to block the overflow path when you need it.
You call, we walk the basin with you, and we tell you what we see in plain terms, no padding the scope. We clear vegetation, pull debris, regrade where water has cut channels, and correct erosion before it undermines the embankment. Then we check that the spillway can actually pass the flow it's rated for and that access to it isn't overgrown or blocked. You get a straight answer about what's needed now and what can wait.
We're a local, family-built company that treats your San Marcos property like our own, tidy crews, clear pricing, and emergency spillway maintenance that holds up to Hays County conditions. Available as a one-time project or part of an ongoing plan.
We come out to the property, usually within 48 hours of your call, and walk the spillway and basin with you or your maintenance contact. We look at vegetation, sediment, slope condition, and the outlet itself, then give you a written scope and a no-obligation estimate before any work starts. There is no charge for the site visit.
It depends on the basin's age and what is upstream, but most sites here need a real inspection and clearing at least once a year, with older or river-adjacent properties needing it more. Heavy spring rain on our thin upland soils moves sediment fast, so a basin that was clean last fall can have a silted forebay or a new volunteer tree by spring.
Slow drawdown after a storm, standing water where there shouldn't be any, a visibly blocked outlet, or erosion cutting toward the embankment are the usual triggers. If your engineer or the county has flagged the spillway during an inspection, that is also a reason to move fast rather than wait for the next scheduled visit.
We schedule around your property's traffic, whether that is a Kissing Tree community with golf cart paths or a student-rental complex near campus with tight parking. Crews stage equipment away from units and walkways, and we coordinate timing with your manager so clearing and grading do not land in the middle of a leasing weekend or a resident event.
How much woody vegetation has rooted into the slope, how deep the sediment is in the forebay, and how much regrading the embankment needs all move the number. A basin with a few seasons of neglect and a mature volunteer tree on the berm costs more to correct than one that just needs debris pulled and the outlet checked for capacity.
