Why this matters

Two kinds of stormwater inspection, and most Texas sites owe both.

Two different rules, two different inspections, and people mix them up constantly. While the job is live, TXR150000 says a qualified person walks the site every seven calendar days and again after any rain of half an inch or more, then signs the log. Once the site is stabilized, the obligation moves to your MS4 and covers the basins and vaults for the life of the property. The walk is half of compliance. The paperwork is the other half, and the half that gets people written up.

Stormwater inspection services for Texas construction sites and commercial property: weekly SWPPP inspections against your Construction General Permit while the job is live, and a photo-documented 40-point inspection of every inlet, swale, basin, outfall, vault, and filter once it is not. Same-day PDF either way.

While the job is live, a SWPPP inspection is a permit obligation with a clock on it. The TCEQ Construction General Permit wants a qualified person walking the site at least every seven calendar days, and again within 24 hours of a storm that drops half an inch or more, with the report signed and dated. We run that route for general contractors across Bexar County and up the I-35 corridor: perimeter controls, inlet protection, the stabilized construction exit, concrete washout, material and waste storage, and every disturbed slope on the property. Anything that needs fixing gets a photo, a location, and a correction deadline, so your superintendent knows what to do Monday morning and the file shows it got done.

Once the site is stabilized the inspection changes shape. Our 40-point inspection is a structured field walk of every stormwater control on the property: storm inlets, conveyance swales, junction boxes, detention and retention basins, outfall structures, energy dissipators, water-quality vaults, and cartridge or media filters. Each of the 40 points carries a pass, a fail, or not applicable, a severity grade (cosmetic, functional, immediate), a written observation, and at least one photograph stamped with timestamp and GPS coordinates. The checklist mirrors what a City of San Antonio, Bexar County, or SAWS inspector opens to when they walk your site: the same fields, in the same order, with the same evidence attached.

A stormwater compliance inspection report does two jobs that usually take two different vendors. It satisfies Bexar County quarterly maintenance reporting and annual permit renewal, City of San Antonio MS4 program audits, HOA recordkeeping, TCEQ Edwards Aquifer reporting where the site sits over the recharge zone, and pre-acquisition due diligence on the documentation side. On the operations side, it gives your property manager or facilities lead a triaged repair list (what to fix this week, what to budget for next quarter, what can wait until the dry season), with cost ranges already attached. Inspectors hold CISEC and CESSWI credentials and have walked the basin and BMP types built across San Antonio, Boerne, Seguin, and New Braunfels for the last fifteen years. They know when a riser is starting to undercut versus when it has already failed, when a hooded inlet is plugged versus designed shallow, when sediment in a forebay is normal accumulation versus a sign the upstream slope is moving.

Our process

How a stormwater inspection runs, from the scheduling call to the PDF in your inbox.

  1. Step 01

    Schedule

    Pick a two-hour window, or put an active job site on a standing weekly route. We coordinate site access, gate codes, and any tenant notice your property manager needs.

  2. Step 02

    Walk site

    One inspector covers the full site with a tablet, GPS camera, and drone when access is tight or the basin is full. Two to four hours on most properties.

  3. Step 03

    Same-day report

    Findings, photos, GPS coordinates, and pass/fail grades compiled into a PDF formatted for your MS4's filing, before the inspector clocks out.

  4. Step 04

    Triage

    Anything graded immediate gets a phone call the same afternoon and a written repair quote inside 48 hours. Routine items go onto your maintenance calendar.

Common questions

What Texas GCs and owners ask before hiring a stormwater inspector.

Perimeter controls, inlet protection, the basin and its forebay, outlet structures, outfalls, stabilized construction exits, concrete washout, material and waste storage, and every disturbed slope on the site. Each point gets a pass, a fail, or not applicable. Every fail gets a photo with GPS and a timestamp.

Same day. The inspector fills the checklist on a tablet while walking your site, and the PDF is in your inbox before the truck leaves the property. Nothing gets written up from memory back at an office three days later.

Yes, and roughly half our inspection work is on plans we didn't write. If the plan doesn't match what's on the ground, you get that in writing with the report so you can decide whether to amend it before an inspector notices the same thing.

It depends on who your MS4 is, not on a single statewide rule. This is the thing people get wrong most often. TCEQ's Construction General Permit governs the job site while it is being built; once the site is stabilized, the inspection and reporting schedule comes from your city or county program. In unincorporated Bexar County that is quarterly maintenance reports and an annual post-construction permit renewal. Inside the City of San Antonio it runs off your recorded maintenance agreement. Over the Edwards Aquifer recharge zone TCEQ has its own annual obligation on top. We read the original approval for your site and tell you which of those you are actually in.

Anything graded immediate gets a phone call the same afternoon, before the PDF lands, and a written repair quote inside 48 hours. Active discharge offsite gets a crew mobilized the same day. We do the repair work in house, so you are not waiting on us to find you a contractor.

That is half of why people order one. Buyers' environmental consultants and lenders both ask for the stormwater maintenance record, and a gap in it turns into a holdback or a retrade. The report is dated, photographed, GPS-stamped, and reads the same to a lender as it does to a city inspector. We have had a few clients order one purely to have the file clean before going to market.

Under TXR150000, at least every seven calendar days, and again within 24 hours of the end of any rain event that drops half an inch or more. Some sites can run every 14 days paired with a post-rain inspection instead, but the seven-day route is what most Bexar County jobs sit on. The seven days is a hard number, not a target. An inspector reading your log counts the gaps.

TCEQ says a qualified person, which it defines by knowledge rather than by a specific license: someone who knows the permit, the control measures, and how to spot when one has failed. In practice, everyone downstream of you (the city, your owner, your insurer, opposing counsel if it ever gets there) treats a CISEC or CESSWI credential as the bar. Ours hold both. If somebody is offering to sign your log without either, ask what happens to that log in an enforcement file.
