Detention and retention pond construction that controls stormwater and meets site requirements.
Detention ponds across Pflugerville earn their keep every time a fast-moving Hill Country storm dumps an inch of rain in twenty minutes. With dense family subdivisions like Falcon Pointe and Avalon built out on tight timelines, and commercial parks pushing right up against drainage easements, these basins carry more load than most people realize until one stops draining the way it should.
The ground here is the real story. Pflugerville sits on heavy black clay that cracks open in a dry spell and then seals shut once the rain starts, which means a basin can look fine in August and back up completely in a September downpour. We see slow drawdown in ponds that have not been touched since the developer turned them over, silted-in forebays below outfall points in older sections of Blackhawk, and volunteer hackberry and elm taking root on embankments where nobody has mowed or inspected in a year or two. Blocked outlet structures are common where construction silt from newer phases of a subdivision never got cleared.
Working with Corral Bros on this scope starts with a straight look at the basin, not a sales pitch. We tell a board or property manager what we actually found, whether that is a grading problem, a failed outlet, or bare slopes that need stabilization, and we scope the work to the plan or alongside the property engineer when one is involved. Estimates are free and usually scheduled within 48 hours.
We're a local, family-built company that treats your Pflugerville property like our own, tidy crews, clear pricing, and detention ponds that holds up to Travis County conditions. Available as a one-time project or part of an ongoing plan.
A detention pond temporarily holds stormwater runoff and releases it slowly, so a developed site doesn't flood downstream neighbors or overwhelm storm drains. Most Central Texas commercial sites, subdivisions and larger developments are required to have detention as part of their drainage permit.
A detention pond drains down to empty between storms and is dry most of the time, while a retention pond holds a permanent pool of water. We build and maintain both, choosing the right one based on your site's soils, drainage requirements and available space.
We walk the basin with whoever is responsible for the property, whether that is a board member, an association manager, or a GC closing out a site. We look at the inlet, the forebay, the outlet structure, and the slopes, and note where sediment or vegetation has changed how the pond drains. Estimates are free and usually scheduled within 48 hours, and in Falcon Pointe or Blackhawk we can often look at the whole drainage easement in one visit.
It depends on the age of the development and how much silt is moving off nearby construction or turf areas, but many basins in newer sections of Avalon and Falcon Pointe need forebay cleanout and slope work every few years. Ponds built more than five or six years ago often need it sooner, since outlet structures silt in gradually and nobody notices until a storm backs up.
We stage equipment and materials inside the drainage easement or detention area itself whenever the site allows it, which keeps crews off drive aisles and visitor parking. For retail centers in the Blackhawk corridor we coordinate timing around peak traffic, and for HOA common areas we let the board or manager know which day work starts so residents are not surprised by machinery near the pond.
The black clay here shrinks and cracks hard in drought, then seals up and sheds water fast once rain returns, so basins often show slow drawdown after a dry spell followed by a heavy storm. That same clay holds moisture around the outlet structure and encourages volunteer trees on embankments, which we remove as part of slope stabilization before root systems compromise the berm.
Size of the basin and the amount of excavation or regrading needed are the biggest factors, along with how much sediment has built up in the forebay and outlet. Slope stabilization work, riprap placement, and whether we are replacing a damaged spillway versus just clearing one also move the number. We give a firm figure after the site walk, not before.
