Construction SWPPP Inspection Logger
Stormwater construction inspections — silt fence, inlets, exits, stabilization, discharge points and rain-event triggers; offline + GPS.
New construction site inspection
Typical CGP rhythm: every 7 days OR every 14 days plus within 24 hours of a 0.25-inch rain event; corrective actions on deadlines.
Field guide: Construction SWPPP Inspection Logger
Construction stormwater is the most-enforced environmental program most builders touch: the NPDES construction general permit turns rain into a compliance event, with inspections due on fixed cycles and within 24 hours of a quarter-inch storm. Fines are written from exactly the findings this logger encodes — silt fence undercut at the low corner, inlet protection bypassing, trackout on the public street (the violation neighbors photograph), and the turbid discharge that puts a plume in the creek.
The trigger field matters legally: routine versus post-rain inspections have different clocks, and 'disturbed more than 14 days without stabilization' is its own permit deadline. Corrective-action classes map to the permit's repair timelines. A dated, GPS-pinned log with photos is the difference between a SWPPP binder that defends you and one that convicts you.
Field tips
- Inspect during rain when you can, not just after — bypassing and overtopping are verbs, invisible once flows recede.
- Walk the downhill perimeter first and the receiving ditch beyond it; offsite evidence outranks onsite tidiness.
- Photograph the rain gauge with the site board in frame on post-rain inspections — it timestamps the trigger itself.

Frequently asked questions
When is a post-rain inspection required?+
Under the federal CGP pattern: within 24 hours of a storm producing 0.25 inches or more (sites on the 14-day routine schedule). State permits vary slightly. Keep a site rain gauge and log readings — 'it didn't rain that much' only works with your own documented gauge.
How full can silt fence get before cleaning?+
Standard threshold: remove sediment when it reaches half the fence height — beyond that, storms overtop and the hydrostatic load flattens fences. Undercutting (flow piping beneath) means it was never trenched in properly; that's reinstallation, not maintenance.
What's the 14-day stabilization rule?+
Areas where work has permanently or temporarily ceased must have stabilization initiated within 14 days (7 in some permits/sensitive waters). 'Initiated' means seeding/mulching actually underway. Inspectors count days from the last soil disturbance — your log's dated entries per area are that count.
Why is concrete washout such a cited item?+
Washwater is caustic (pH ~12) and lethal to aquatic life — a washout overflowing to a storm drain is a quotable water-quality violation, not housekeeping. Lined washouts maintained below capacity, signed, and actually used by drivers (check for rogue washout stains) are the audit standard.
