Detention and retention pond construction that controls stormwater and meets site requirements.
Detention ponds in Canyon Lake do more work than in most of the Hill Country, because the slopes feeding them are steep and the soil is thin. A basin that was graded correctly when Canyon Lake Hills, Mystic Shores, or Startzville was first developed can still fall behind once the surrounding rock sheds water fast and the fill soil on the berms never had much topsoil to begin with. The property stays dry right up until a hard rain shows the basin was not keeping pace.
On these lots the signs tend to be the same. Runoff off exposed limestone and caliche carries fine sediment straight into the forebay, so the first cell silts in years before the rest of the pond does. Embankments that were seeded once and never mowed grow volunteer cedar and mesquite, and those roots work into the same slopes that are already marginal for stability. Outlet structures clog with gravel washed down from the rock cuts above, which shows up as standing water that will not draw down between storms, a problem a board usually hears about from a resident before anyone on-site notices it.
Working with us on this scope starts with a walk of the pond and its inflow points, not a form filled out from a satellite photo. We tell the property manager or board what is actually causing the slow drawdown or the bare slope, what has to be excavated or regraded, and what outlet or spillway work the fix calls for, built to the plan on file or alongside your engineer if the site has one. You get a straightforward look at the basin before anything is scheduled.
We're a local, family-built company that treats your Canyon Lake property like our own, tidy crews, clear pricing, and detention ponds that holds up to Comal 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 pond, the inlet and outlet structures, and the slopes feeding it, then give you a free on-site estimate, usually scheduled within 48 hours of your call. For HOA and POA boards we will point out specific problem areas, like a silted forebay or a bare embankment, so the board understands what it is approving before any excavation or grading starts.
There is no fixed interval, but Canyon Lake's steep, rocky drainage tends to silt in forebays and clog outlet structures faster than flatter sites, so basins here often need attention sooner than the design life would suggest. A slow drawdown after a normal rain, standing water that lingers, or visible sediment buildup at the inlet are the usual triggers for a call.
Shallow soil over rock means less material holding the slopes together, so erosion shows up faster on bare embankments and cut slopes around Canyon Lake Hills and Mystic Shores than it would on deeper soil elsewhere. That is why riprap, liners, and proper slope stabilization matter more here than a quick reseed, and why grading has to account for rock close to the surface.
We schedule excavation, grading, and structure work to keep access and parking open wherever the site allows, and we coordinate timing with the property manager or association before equipment shows up. Detention ponds usually sit apart from buildings and parking fields, so most of this work has limited direct impact on residents or tenants once access routes are worked out in advance.
The size of the basin, how much sediment or vegetation has to be removed before grading can start, the condition of the existing outlet and outfall structures, and how much riprap or liner the slopes need all factor in. A pond needing a full regrade and new spillway costs more than one that just needs its outlet cleared and slopes stabilized, which is why we price after the site walk, not before.
