BMP Maintenance & Repair
Maintenance is where a stormwater program is won or lost: the controls that pass inspection are the ones somebody looked at, cleaned, and stood back up between inspections. Terradyne runs that between-inspections work across Dallas–Fort Worth — the cleaning, the repairs, and the record that shows both happened.
What is BMP maintenance?
The permit's quietest obligation. Under TXR150000, all protective measures identified in the SWP3 must be maintained in effective operating condition. Installation gets the attention, but the maintenance sentence is the one inspections test, inspection after inspection — a control that was working at install and failing at inspection is a finding all the same.
The triggers are written down
Maintenance in this trade is not a judgment call; the thresholds are in the permit. For perimeter controls such as silt fence, TXR150000 requires trapped sediment to be removed before it reaches 50 percent of the control's above-ground height. Sediment must be removed from sediment traps and sedimentation ponds no later than when design capacity has been reduced by 50 percent. A crew that measures sediment against those lines — instead of eyeballing "probably fine" — is the difference between a maintenance program and a pile of reactive callouts.
What a maintenance visit actually is
Terradyne fields dedicated crew work for installation, maintenance, repair, and removal labor — including skid-steer crews that clean accumulated silt from controls. The work is unglamorous on purpose: shovel the toe line, stand the sagging run back up, re-drive the leaning post, haul the spoil where it belongs. The cheapest maintenance visit is the one scheduled before the inspector's deadline, not after it.
Where maintenance sits in the pricing
Unless a maintenance line is sold, Terradyne's install prices cover installation only — repairs, cleaning, and removal are separate maintenance work. That split is worth understanding at bid time: the install line buys a working control on day one, and the maintenance line is how it stays working through month six.
The record that proves it
Maintenance that is not documented might as well not have happened when the reviewer asks. Terradyne provides routine SWPPP inspection reports with cloud-based client access. The inspection reports and the maintenance visits reference each other — the report flags the sag, the visit fixes it, the next report shows it standing. See SWPPP Inspections for the reporting side, and Silt Fence Installation for the control that takes the most maintenance love.
Frequently Asked Questions
How often do BMPs need maintenance?
On the permit's triggers, not a calendar: sediment out of perimeter controls before it reaches half the control's height, basins cleaned before capacity halves, and everything kept in effective operating condition between inspections.
What does a BMP maintenance visit include?
Cleaning accumulated silt, restanding or re-driving fence and posts, repairing damaged runs, and hauling off the spoil — a crew with a skid-steer and shovels doing the physical work the inspection report asked for.
Is maintenance included in the installation price?
No — unless a maintenance line is sold, install pricing covers installation only, and repairs, cleaning, and removal are separate work. Ask for the maintenance line up front if you want the program, not just the product.
Who tracks that maintenance actually happened?
The inspection record does. Reports flag the deficiencies, the maintenance visit clears them, and the next report shows the fix — a loop the whole team can watch in the cloud.
