Inspection, cleaning and maintenance of stormwater best management practices, from ponds and swales to filters and underground structures.
Stormwater BMP maintenance in San Antonio is not optional upkeep, it's what keeps a detention pond, swale or underground structure doing the job it was designed and permitted to do. Bexar County's caliche-heavy soils and limestone shelves don't absorb water the way engineers in wetter regions might assume, which puts more weight on the pond, the outlet structure and the vegetated slopes to manage every storm correctly. When one of those pieces is neglected, the whole system falls behind.
We see it the same way in Stone Oak, Alamo Heights and Shavano Park, just at different ages. New construction sites built over compacted caliche often show slow drawdown because the subsoil won't take water, plus bare or eroded slopes where turf never caught on that hard ground. Older, established properties tend to show a different problem: a silted-in forebay from years of runoff, a blocked or rusted outlet structure, or volunteer trees rooted into an embankment that was never supposed to grow anything taller than grass.
Working with Corral Bros on this scope starts with a straightforward site walk, not a sales pitch. We tell you what we see in the pond, the swale, the filters and the underground structures, and what it will take to bring the system back to where it should be. From there we handle the pond, swale, filtration and underground maintenance, the drainage control inspection and the documentation your association, lender or closing contractor needs, so the person responsible for the property isn't left guessing.
We're a local, family-built company that treats your San Antonio property like our own, tidy crews, clear pricing, and stormwater bmp maintenance that holds up to Bexar 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 you or your engineer's drawings if you have them. We look at the inlet, the forebay, the outlet structure and the slopes, note what's silted in or overgrown, and give you a straightforward scope and estimate before any work starts.
Most Bexar County sites need a real inspection and cleanout at least once a year, but a hard rain event, visible silt buildup in the forebay, standing water that won't draw down, or a board or manager noticing erosion on a slope should trigger a look sooner. New Stone Oak developments with loose fill often need more frequent attention in the first few years than older Alamo Heights lots.
Yes, we schedule around your property's traffic and coordinate with management or the HOA board ahead of time so residents and tenants know what to expect. Most pond, swale and structure work happens away from parking and building entrances, and we keep equipment staged to limit disruption to daily use of the site.
Caliche soils and limestone shelves here mean water doesn't infiltrate the way it does in sandier soils, so basins depend on their outlet structures and vegetated slopes doing their job correctly. Add in the area's intense, infrequent rain events and you get fast-filling basins, silted forebays, and bare or eroded slopes where grass never established on that hard ground.
Access and size drive most of the cost, along with how much sediment has built up in the forebay or underground structure and whether slopes need regrading or reseeding. A Stone Oak basin with a clear access road costs less to service than an older Alamo Heights lot where equipment has to come in through a tight easement or around mature trees.
