Visual inspection of stormwater facilities that catches sediment buildup, erosion, blockages, overgrowth and structural damage before they become problems.
Thin clay sitting over bedrock does not absorb much, so Universal City's stormwater facilities have to do the work the soil cannot, and that only holds true if the basin is actually functioning the way it was built.
In Forest Crest and Northview, older detention basins built decades ago often show slow drawdown after a storm, because sediment has worked its way into the forebay and narrowed the path water is supposed to take. In Olympia Hills, newer construction sites tend to have bare slopes still settling in, and those can erode fast when runoff comes off bedrock-backed clay with nowhere else to go. Near Randolph, embankments that have gone unmowed for a season or two often have volunteer trees taking root right where the outlet structure needs clear access. None of this shows up from the road. It shows up when someone walks the facility and looks at the outfall, the slope, and the bottom of the pond.
Working with Corral Bros on this starts with a call and a site walk, usually scheduled within 48 hours, and the estimate costs nothing. We walk the full facility, check for sediment and blockages, assess the slopes for erosion, and look over the structure and outfall. You get written findings and recommendations you can take to your board, your ownership group, or the property engineer, so the next decision is an informed one instead of a guess.
We're a local, family-built company that treats your Universal City property like our own, tidy crews, clear pricing, and stormwater system inspection that holds up to Bexar County conditions. Available as a one-time project or part of an ongoing plan.
You call or request a visit, and we schedule a free on-site walk, usually within 48 hours. We walk the full facility together or on your schedule, look at the sediment, slopes, structure, and outfall, and give you a clear picture of what we find before any work is quoted. There is no obligation tied to the walk.
Most HOA and commercial basins in this area hold up well with an inspection once or twice a year, but a heavy rain event, a change in drawdown speed, or standing water where there was not standing water before should trigger an extra look. Thin clay over bedrock means runoff behaves differently than in sandier soil, so changes tend to show up fast.
We plan the walk around your property's traffic, not the other way around. For apartment and retail sites in Northview or Olympia Hills, that usually means timing the inspection for lower-traffic hours and staying clear of active parking and walkways. For HOA common areas, we coordinate directly with the board or management company on access.
Thin clay over bedrock near Randolph does not drain the way deeper soil does, so water moves fast off hard surfaces and slows down hard once it hits a basin. That combination tends to produce silted forebays, slow drawdown, and erosion on slopes that were never fully stabilized, especially on sites built or regraded in the last several years.
Size and access are the two biggest factors. A single retention pond behind a retail center is a quicker walk than a multi-basin system tied to a large apartment community or an HOA with several common areas. Overgrowth, difficult slope access, and how far the structure sits from a drivable point also affect the time on site.
