Inspection, cleaning and maintenance of stormwater best management practices, from ponds and swales to filters and underground structures.
Hill Country storms over Comal County tend to arrive fast and hard, dumping an inch or more in under an hour, then nothing for weeks. That pattern is what makes stormwater BMP maintenance in New Braunfels a different kind of job than it is in flatter, steadier-rainfall parts of the state, and it is why property managers from Gruene to Vintage Oaks end up calling us after a big rain rather than before one.
The ground here does a lot of the work for us figuring out what is wrong. Rocky edge-of-Hill-Country soil sheds water quickly and carries grit straight into a forebay, so we find silted-in forebays and basins that draw down slower than they should. Closer to the river, sandier soil moves differently, undercutting outlet structures and letting banks slump. Add in volunteer trees that take root on an embankment within a couple of growing seasons, and a basin that looked fine at handover can be holding water wrong three years later.
Working with Corral Bros on this scope means one site walk, one scope of work, and a crew that tells you what we actually found, not a generic checklist. We handle pond, swale and basin upkeep, filtration and separator cleaning, underground structure maintenance, and drainage control inspection, with compliance-ready documentation for your board or your property engineer. We are locally owned, licensed and insured, and estimates are free and usually scheduled within 48 hours. Call (737) 404-9343.
We're a local, family-built company that treats your New Braunfels property like our own, tidy crews, clear pricing, and stormwater bmp maintenance that holds up to Comal 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 basin or structure with whoever manages the property. We look at inlets, the forebay, side slopes and the outlet, then put together a scope before anyone commits to anything. For HOA and POA boards, we are glad to meet during a board meeting or site visit window if that works better.
Most Comal County basins need a real inspection and cleaning once or twice a year, more often if the site took on heavy sediment from a construction phase nearby or sits downstream of exposed Hill Country edge soils. A big storm event is also a trigger. If you are not sure where your system stands, that is what the walk is for.
Yes. We coordinate timing with property management so we are not blocking fire lanes, resident parking or retail customer spots at places like Vintage Oaks or River Chase. Most BMP work happens at the edge of a site, away from the main building, so disruption to daily traffic is usually minimal.
Rocky Hill Country edge soils shed water fast and carry grit into forebays, so we see silted-in forebays and slower drawdown more than soft clay buildup. Riverfront and Gruene-area lots with sandier ground tend to show bank erosion and undercut outlets instead. Both conditions call for different maintenance, which is why we look at the actual soil on your site rather than guessing.
Access is the biggest factor, a basin you can drive equipment to costs less to maintain than one tucked behind a retaining wall or down a steep bank. Sediment volume, the condition of underground structures, and whether trees or brush have taken root on an embankment all affect the scope. We price it after the walk, not before.
