Detention and retention pond construction that controls stormwater and meets site requirements.
Marble Falls has a mix of older Highland Lakes resort developments and newer granite-country ranch subdivisions, and the detention ponds built to serve them show their age differently depending on which category they fall into. A basin built twenty years ago near Horseshoe Bay often has a concrete outlet structure that has never been reworked, while a newer pond out toward Gregg Ranch may just need its first real grading pass since construction.
The ground here does a lot of the talking once you look closely. Pink granite sits close to the surface on much of this ground, so basins dug into it hold water differently than a clay-bottomed pond would, and outlet structures set into rock can shift or crack in ways a flat-ground pond never does. Rain off the lake tends to arrive in short, hard bursts rather than steady soaking rain, which loads a forebay with silt fast and can leave an outlet pipe choked with gravel and debris within a season or two. Slopes that were never stabilized after the original grading often show bare patches, erosion channels, or volunteer cedar and mesquite taking root in the embankment.
Working with Corral Bros on a detention pond in Marble Falls starts with a site walk, usually within 48 hours of your call, where we look at the basin the way an owner who has to answer for it would want it looked at. From there we handle the excavation, grading, structures and slope work to bring the pond back to where it needs to be, working to the plan or alongside your property engineer where one is involved. We are locally owned, licensed and insured, and we work commercial sites around parking, tenants and association schedules as a matter of course.
We're a local, family-built company that treats your Marble Falls property like our own, tidy crews, clear pricing, and detention ponds that holds up to Burnet 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 or your engineer, note the inlet and outlet condition, check drawdown and look at the slopes and liner. You get a free no-obligation estimate, usually scheduled within 48 hours of your call. On granite-heavy sites we flag any rock we expect to hit during excavation or grading before we quote the work.
Most basins in Gregg Ranch, Meadowlakes and Horseshoe Bay need a real look every few years, sooner if a big rain event silts the forebay or knocks debris into the outlet structure. Triggers include slow drawdown after storms, standing water past the design window, bare or slumping slopes, or an HOA or buyer's inspection ahead of a sale or handover.
Yes. We schedule around leasing offices, pool hours and resident traffic, and we stage equipment to keep drive aisles and visitor parking open. For gated communities and resort properties around Horseshoe Bay and Meadowlakes we coordinate access with the association or property manager ahead of time so nobody is surprised by a crew on site.
Pink granite outcrops sit close to the surface on a lot of these lots, which changes how we excavate, grade and set outlet and spillway structures compared to straight clay sites. Rainfall here tends to come in bursts off the lake basin, so forebays silt up fast and slopes that were never stabilized erode or grow volunteer trees along the embankment.
The main drivers are how much excavation and grading the basin needs, how much rock we hit, the condition of the inlet, outlet and outfall structures, and how much slope stabilization, riprap or liner work the embankments need. Access for equipment and how much silt has built up in the forebay also factor in. We price it after the site walk, not before.
