Detention and retention pond construction that controls stormwater and meets site requirements.
Detention ponds around Elgin earn their keep on the days between droughts, when a fast Hill Country thunderstorm dumps on the 290 corridor and the basin either holds that water or sends it somewhere it shouldn't go. Most of the ponds we see here were built to a plan that made sense on paper. Keeping them working the way that plan intended is a different job, and it's an ongoing one.
Elgin's ground doesn't make it easy. Sandy loam near the surface drains fine until you hit the blackland clay underneath, and that clay is what controls how fast, or how slowly, a basin actually draws down after a storm. We find forebays silted in from sheet flow off newer lots, slopes left bare after grading that never got stabilized, and embankments with volunteer hackberry and cedar elm doing real damage to the structure underneath. A blocked or undersized outlet is a common finding on older properties near downtown, especially where the pond has sat untouched since the site was built out.
For a property manager or board handling this, our process starts with a site walk so we can see the basin in its current condition, not off a ten-year-old plan set. From there we build and maintain the pond to that plan, or alongside your project engineer if the system needs an engineering call. You get a crew that shows up, does the excavation, grading, structure, and slope work on schedule, and leaves the site in working order.
We're a local, family-built company that treats your Elgin property like our own, tidy crews, clear pricing, and detention ponds that holds up to Bastrop 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, no-obligation site visit, usually within 48 hours of your call, and walk the basin with you or your maintenance contact. We look at drawdown, the inlet and outlet structures, slope condition, and sediment buildup in the forebay, then put together a scope based on what the pond actually needs, not a generic checklist.
It depends on the site, but sediment load from sandy loam runoff and clay drawdown issues tend to show up faster here than in rockier parts of the Hill Country. Many properties need basin or forebay cleanout and slope checks every one to three years, with erosion repairs triggered sooner after a heavy rain year or new development upstream that changes the runoff pattern.
We stage equipment and materials to keep drive lanes and parking counts intact wherever the site allows, and we schedule the noisier excavation and grading work for times that fit your property's traffic patterns. On apartment and retail sites we coordinate directly with your on-site manager so residents and shoppers aren't surprised by equipment on the property.
The sandy loam over blackland clay combination means water moves fast until it hits that clay layer, then it sits, so basins here are prone to slow drawdown and silted forebays if they're not maintained. Sudden heavy rain after dry stretches, which is common along the 290 corridor, also accelerates erosion on bare or under-stabilized slopes.
Size and depth of the basin, how much sediment has to come out, the condition of the existing inlet, outlet, and outfall structures, and how much slope stabilization or riprap work is needed all factor in. Access matters too. A pond tucked behind a retail center with tight equipment access costs more to work than an open basin on a rural homestead lot.
