Detention and retention pond construction that controls stormwater and meets site requirements.
Detention ponds across Liberty Hill, from Santa Rita Ranch to Rancho Sienna and out toward Stonewall, are doing more work than most boards realize. These master-planned sites were graded fast on rolling limestone hills, and the basins built to hold that runoff were sized for a neighborhood that is still filling in. As more roofs and pavement go up around them, the pond is catching more water off more hard surface than it did on the day it was approved.
That shows up in predictable ways once you walk the basin. Thin ranch soil over limestone does not hold a slope the way deeper soil does, so bare embankments wash out fast and send sediment straight into the forebay. A pond that used to drain overnight starts holding water for days because the outlet structure is half buried in silt nobody has pulled out. Volunteer trees and brush take root on the dam face within a season or two if nothing is cut back, and their roots do the embankment no favors. These are the things we find when we get out of the truck and into the basin.
Working with us on this looks straightforward. We walk the pond with you, tell you what we see in plain terms, and scope the excavation, grading, outlet work, or slope stabilization the site actually needs, whether that is a full basin rebuild for a developer closing out a phase or a seasonal cleanout for an HOA board. If the property has an engineer of record, we build to that plan. If not, we tell you what we would do and why, and you decide.
We're a local, family-built company that treats your Liberty Hill property like our own, tidy crews, clear pricing, and detention ponds that holds up to Williamson 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 schedule a free on-site visit, usually within 48 hours of your call, and walk the basin with whoever manages the property, often a board member or community manager. We look at the inlet, outlet, forebay, and slopes, check drawdown and note any erosion or blockage. You get a clear picture of what the basin needs before any work starts, and if there is a site engineer of record we coordinate the scope with their plan.
Most basins in Santa Rita Ranch, Rancho Sienna, and Stonewall need some grading, desilting, or slope work every few years, sooner if a construction phase upstream is still sending sediment into the pond. New developments tend to need attention earlier than people expect, because fresh grading and thin ranch soil erode fast before grass and groundcover take hold. An annual walk-through after heavy rain is a reasonable baseline for most associations.
We stage equipment and materials as far from traffic lanes and common areas as the site allows and keep access open to parking and buildings throughout the job. Detention basins usually sit at the edge of a property, away from where people live and work, so most of this scope does not touch resident or tenant activity directly. We coordinate timing with your property manager or board so everyone affected knows what to expect.
Thin soil over limestone does not absorb water the way deeper soil does, so basins here fill fast in a storm and can be slow to drain afterward if the outlet structure is even partly blocked. Hill Country downpours after dry stretches move a lot of sediment off bare slopes in a short time, which silts in forebays and buries riprap. These conditions push basin maintenance here toward more frequent desilting and slope stabilization than you would see on flatter, deeper-soil sites.
The biggest factors are how much sediment has to come out, how far equipment has to travel across the site to reach the basin, and how much slope stabilization or riprap work the embankments need. A pond with a clogged outlet and bare, eroding slopes costs more to put right than one that just needs routine desilting. We price each job after the site walk, once we know the actual condition of your basin rather than guessing from a satellite photo.
