ONE PROBLEM, IN DETAIL

SWPPP / EROSION CONTROL: THE RAIN-EVENT CLOCK

QUICK ANSWER

Most permits require inspection within 24 hours of a 0.25-inch rain event, on top of routine weekly or biweekly cadence. Rain events are unscheduled, simultaneous across every site in the portfolio, and contractually mandatory: the definition of surge staffing.

This page covers one problem. The full picture for this trade, including the other places margin leaks, is on the swppp / erosion control operating system page.

WHAT THE NUMBERS SAY

THE COST, SOURCED.

Sourced language

"Almost all jurisdictions require an additional 'rain event' inspection within 24 hours of a storm of a certain size (usually 0.25 inches)." (ROI Safety Services, 2026)

WHAT THIS TRADE SHOULD EARN

THE NUMBER TO MEASURE IT AGAINST.

SWPPP / Erosion Control contractors run about % net profit at $1M to $5M, rising to roughly 13% at $5M to $10M. The CFOS target at $1M to $5M is11%, set at 10 percent before taxes or 3.5 points better than your trade's average at your revenue, whichever is higher. A problem like this one lives in the distance between those two figures rather than in a loss on any single job.

Gross margin over the same bands runs % to 26%, against a CFOS target of 11%.

COMMON QUESTIONS

FREQUENTLY ASKED.

As their own rate class, above routine inspection pricing. A quarter-inch storm triggers 24-hour inspections across every site simultaneously; that's emergency surge work, and pricing it at route rates donates the hardest hours in the business. Put the trigger, the window, and the rate in the contract.
Three tiers, and which one you are in depends on how much of the work you want off your desk. Core is where you stop guessing: job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a monthly meeting that ends in decisions, while your bookkeeper keeps doing the books. Executive is where you stop touching the books, because we run the bookkeeping and the controllership as well. Strategic is where every job shows its margin while it is still running, because the job costing and WIP platform is set up and managed for you. No payroll. No scope gaps.
