Detention and retention pond construction that controls stormwater and meets site requirements.
Walk a detention basin in Seguin after a few years of light upkeep and you will usually find the same things: a silted-in forebay, a slope where volunteer pecan saplings have taken hold, and an outlet structure half-choked with leaf litter and river silt. We see this pattern across Starcke Park, Mill Creek, and Navarro, on both older POA ponds and newer sites still under a developer's punch list.
Guadalupe River bottomland is rich and heavy, and it does not drain the way sandier soil does. Combined with pecan shade that keeps slopes damp longer, that means slower drawdown after storms, more silt moving into the forebay with every rain event, and bare or eroding slopes where grass never got a foothold. Historic pecan-town lots along the river often have basins built to an older standard that was fine at the time but is undersized or under-stabilized for what the site handles now.
For a property manager or board member, working with us on this scope means a site walk where we look at the actual basin, not a file photo, then a plain scope covering excavation, structure work, and stabilization as needed. We build and grade to the plan or alongside your project engineer, and we handle the dirt, the slopes, and the structures so the system does what it is supposed to do when the water comes.
We're a local, family-built company that treats your Seguin property like our own, tidy crews, clear pricing, and detention ponds that holds up to Guadalupe 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 you, check the inlet and outlet structures, note how the forebay and slopes are holding up, and look at drawdown after the last rain if we can. From that we put together a scope for grading, stabilization, or structure repair. Estimates are free, no obligation, and we usually get out within 48 hours of your call.
It depends on the site, but pecan-town lots along the Guadalupe tend to need attention every year or two, especially after a wet spring pushes silt and leaf litter into the forebay. Older POA and HOA basins near Mill Creek and Navarro that have not been regraded in a while often need more. An annual walk-through catches most issues before they become a drawdown problem.
We stage equipment off drive aisles and out of marked spaces wherever the site allows, and we coordinate timing with the property manager or board so excavation and grading do not block leasing traffic or resident access. Most of this work happens in and around the basin itself, away from buildings and parking lots, so day-to-day activity on site is not disrupted.
The Guadalupe River bottomland here holds rich, heavy soil that silts in forebays fast and lets volunteer trees take root on embankments if slopes go a season or two unchecked. Pecan shade keeps some slopes damp longer, which slows drawdown and invites erosion at the outfall. Riprap and proper liner work hold up better here than bare clay slopes do.
The main factors are how much excavation and regrading the basin needs, the condition of the inlet and outlet structures, how much erosion or slope stabilization is involved, and site access for equipment. A basin that just needs riprap and spillway work costs less than one needing a full regrade and new outfall structure. We will lay out the scope plainly after the site walk.
