Pond and stormwater water-quality management that keeps water clean, clear and compliant.
Water quality management is the work that keeps a detention or retention basin doing its job instead of just sitting there collecting silt and trash. In Universal City, the properties that need it most are the established neighborhoods and associations near Randolph AFB, where basins built decades ago now serve mature landscaping, military housing turnover, and runoff patterns that have shifted as the area filled in around them.
The ground here is the real issue. Thin clay sits over bedrock through much of Forest Crest, Northview, and Olympia Hills, so water does not infiltrate the way it would in deeper soil. It runs off fast, carries sediment into the forebay, and leaves basins slow to draw down after a storm. We regularly find bare or slumping slopes where grass cover never took, volunteer trees rooting into embankments, and outlet structures choked with silt and leaf litter that nobody noticed until the water stopped moving.
Working with Corral Bros on this scope means one point of contact who walks the basin with you, tells you what is actually going on in plain terms, and does the maintenance, sediment removal, and vegetation control the system needs to stay compliant and functional. If an engineer is attached to your property, we work alongside their plan rather than around it. You get a crew that shows up, does the work, and leaves the basin performing the way it was designed to.
We're a local, family-built company that treats your Universal City property like our own, tidy crews, clear pricing, and water quality management that holds up to Bexar County conditions. Available as a one-time project or part of an ongoing plan.
Water-quality management keeps ponds and stormwater features clean and compliant, removing sediment and pollutants, controlling algae and nuisance vegetation, maintaining filtration and outfall structures, and supporting any required water-quality monitoring. It protects both the system and the downstream waterways it drains to.
Yes. We manage the sediment, nutrients and vegetation that turn a pond green and murky, keeping the water clearer and the basin functioning. For commercial and HOA ponds we can set this up on a recurring schedule so it stays clean year-round.
We walk the basin with you, usually within 48 hours of your call, and look at the forebay, outlet structure, and vegetation line before we quote anything. In Forest Crest and Olympia Hills we also check how water is actually drawing down after a rain, since that tells us more than a dry-day look ever will. The estimate is free and there is no obligation to book.
Most of the established basins we see on the northeast side need a real service visit once or twice a year, with a lighter check after any heavy rain event. Older basins near Northview with mature landscaping tend to silt in faster and need more frequent sediment checks. What triggers an unscheduled visit is usually standing water that will not drop, a clogged outlet, or algae that has gone from green film to solid mat.
We schedule around your property's traffic patterns, not the other way around, and we coordinate timing with the property manager or board contact ahead of the visit. Around Randolph AFB many residents keep irregular hours, so we are used to working quietly and keeping access clear for parking and foot traffic. Equipment stays contained to the basin and outfall area while we work.
That ground does not let water infiltrate the way deeper soil does, so basins here rely almost entirely on the outlet structure and vegetation to manage flow and filter pollutants. When clay compacts near bedrock, slopes erode instead of absorbing runoff, which pushes sediment straight into the forebay. We see this show up as slow drawdown, bare or slumping embankments, and outlets that choke with silt faster than you would expect.
The biggest factors are how much sediment has built up, how overgrown the vegetation and volunteer trees have gotten on the embankment, and whether the outlet structure is clear or blocked. A basin that has gone a few years without attention costs more to bring back into shape than one on a regular schedule. We price it after the site walk, not before, so the number reflects what is actually in your basin.
