Excavation and removal of built-up sediment to restore a detention pond's designed storage, drainage performance and access.
Property managers and HOA boards around New Braunfels usually call us after a pond stops draining the way it used to, maybe standing water for two or three days after a storm that used to clear overnight, or a forebay that has gone from a foot deep to a few inches. By the time the call comes in, the board has usually already fielded a complaint or a GC is trying to close out a punch list before turnover.
The ground here does a lot of the work of filling these basins in. Rocky Hill Country edge soils around Vintage Oaks shed fast once a slope loses cover, and riverfront sand near Gruene and River Chase moves hard in a flood pulse off the Guadalupe watershed. We find silted-in forebays, bare and rilled embankments, volunteer trees rooted into the slope, and outlet structures half-buried in sediment more often here than on flatter, older sites. New development along these corridors compounds it, since a basin built to handle a stabilized watershed is often still catching runoff off exposed cut slopes and fresh grading for a year or two after construction.
Working with us on this looks like a site walk first, where we check actual sediment depth rather than guess from the bank. We give you a number before anything gets scheduled, do the excavation and hauling without turning your parking lot or common area into a staging yard, and leave the basin at its design grade with the outlet and forebay clear. If there's a property engineer involved, we work to the plan they've set rather than making grading calls on our own.
We're a local, family-built company that treats your New Braunfels property like our own, tidy crews, clear pricing, and detention pond sediment removal that holds up to Comal County conditions. Available as a one-time project or part of an ongoing plan.
We walk the basin with whoever manages the property, whether that is a board member, a community association manager, or a GC closing out a site. We check sediment depth at the forebay and main pool, look at the outlet structure, and note any slope erosion. Estimates are free and usually scheduled within 48 hours, and you get a straightforward number before anything is scheduled.
It depends on the watershed above it and how long the pond has been in service. A basin catching runoff off caliche cuts in Vintage Oaks or new rooftops near River Chase can silt in faster than an older, stabilized Gruene-area pond. If drawdown has slowed noticeably after a storm, or the forebay looks shallow compared to a year ago, it is time to check.
Most of these ponds sit at the edge of a parking lot, a retail pad, or a common area, so we plan hauling routes and staging to keep drive aisles and resident access open. We coordinate timing with the property manager or board ahead of the work and keep equipment contained to the basin footprint rather than spreading across the lot.
Rocky Hill Country edge soils around Vintage Oaks and the acreage developments hold back erosion less than you'd think once bare slopes form, and riverfront sand near Gruene moves fast in a hard rain. Heavy, fast-moving storms off the Hill Country edge can load a basin with sediment in a single event, which is why forebays here silt in faster than flatter sites.
Volume of sediment, access for hauling equipment, and disposal distance are the three biggest factors. A pond with a tight access road or volunteer trees grown into the embankment takes longer to clear than an open basin. We price it after the site walk once we know actual depths, not off a guess.
