Cleaning, mowing, grading, vegetation control, debris removal and erosion repair for drainage swales, channels, ditches and culverts.
Swale, channel and culvert maintenance is a different job in Manor than it is almost anywhere else in the metro, mostly because of how fast this part of Travis County is building out. ShadowGlen, Whisper Valley and Stonewater are adding streets, lots and impervious cover every year, and every acre of new roof and pavement sends more water into the same swales and culverts that were sized for a quieter neighborhood. Systems that looked adequate at the ribbon cutting are already working harder than they were designed to.
On the ground, that shows up in predictable ways. Manor sits on deep blackland clay, which cracks and hardens in dry weeks, then sheds water almost immediately once a storm arrives because it will not absorb runoff fast enough. We find forebays silted in from that first flush, culvert inlets packed with sediment and construction debris, bare slopes where turf never caught on a steep new embankment, and volunteer trees and brush rooting into channel banks within a season or two of grading. None of it is unusual for new construction on this soil, but it does not fix itself.
Working with Corral Bros on this scope starts with a straightforward site walk, usually scheduled within 48 hours of your call. We look at the whole path, swale to channel to culvert, and tell you plainly what needs cleaning, mowing, regrading or erosion repair now versus what can wait a season. You get a scope and a plan, we do the work to the property engineer's design where one exists, and your system keeps moving water the way it is supposed to.
We're a local, family-built company that treats your Manor property like our own, tidy crews, clear pricing, and swale, channel & culvert maintenance that holds up to Travis County conditions. Available as a one-time project or part of an ongoing plan.
We walk the full drainage path with you or your maintenance contact, from the inlet swales down through the channel to the culvert outfall, and note where sediment, vegetation or erosion are causing problems. The estimate is free with no obligation, and we usually get out to the property within 48 hours of your call. You get a clear scope before any work starts.
Most of the newer subdivisions out here need a real cleaning and vegetation pass once or twice a year, but a hard rain event can move that timeline up fast. Blackland clay sheds water quickly once it is saturated, so a single heavy storm can silt in a forebay or undercut a slope that looked fine a month earlier. We recommend a walk-through after any significant rain, not just on a fixed calendar.
We schedule around your property's traffic patterns and coordinate access through your manager or board contact so equipment is not blocking fire lanes, resident parking or retail entrances during business hours. Most swale and channel work happens along common-area easements away from units, and culvert clearing is usually a short, contained job rather than a multi-day disruption.
The deep blackland clay out here does not absorb water quickly, so it compacts, cracks in dry spells, and then sheds runoff fast once storms hit, which pushes silt and debris straight into channels and culvert inlets. We regularly find slow drawdown from a silted forebay, bare or slumping slopes where grass never established, and volunteer trees taking root on embankments in the newer ShadowGlen and Whisper Valley sections. Left alone, these turn into bigger grading and erosion repairs.
The main factors are how much sediment and debris have built up, how much grading or reshaping the banks need, how overgrown the vegetation is, and how many culvert crossings are involved. A newly built site closing out construction often needs less than an older section that has gone a year or two without attention. We price it after the site walk, not off a phone description.
