A SWPPP is not a generic form — it’s a site-specific plan that ties your site conditions, drainage, controls (BMPs), inspections, corrective actions, and stabilization approach into a coherent compliance story. More moving parts = more coordination and documentation.
What usually makes a SWPPP “simple”
- Single phase, clear limits of disturbance, basic access and laydown areas
- Standard erosion/sediment controls with obvious drainage patterns
- No unusual dewatering, no sensitive receiving water complexity
- Minimal offsite run-on and fewer discharge points
What you get in the workflow
- Before checkout: narrative PDF preview (review scope, story, assumptions)
- After purchase: final SWPPP PDF package aligned to an Idaho CGP workflow
What increases effort (and therefore cost)
These are the common drivers that add coordination and documentation. None of them are “bad” — they just require more careful planning.
Phasing & sequencing
- Multiple phases with moving BMP locations
- Stabilization timing changes as work shifts
- More places where “field vs plan” can drift
Mapping complexity
- Multiple discharge points / outfalls
- Tight urban work with inlets and traffic constraints
- Steeper slopes or constrained conveyances
Sensitive receiving waters
- Higher consequence if controls fail
- More attention to routing, containment, and documentation
- More careful narrative around risk controls
Dewatering considerations
- Where water goes (storm drain, ditch, infiltration, tank)
- Treatment controls and operational checks
- More moving parts in the inspection/corrective-action story
Quick checklist: what to prepare (to keep it fast)
These inputs reduce “back and forth” and help keep the narrative preview accurate the first time.
- Project address and a site plan / exhibit (best available)
- Limits of disturbance and rough phasing notes (even if not perfect)
- Known drainage direction / discharge points (photos help a lot)
- Contacts list: operator, responsible parties, inspection responsibility
- If dewatering is likely: basic notes (where it goes, any treatment assumptions)
FAQ
Why is pricing a flat $875 — and what can still change the timeline?
Pricing is fixed at $875 per SWPPP for the Idaho CGP workflow so you can budget without surprises. What can still vary is turnaround: site complexity, phasing, dewatering, mapping needs, sensitive receiving waters, and the completeness of project inputs can add iteration before the final package is delivered.
What is the “preview” step and why does it matter?
The narrative PDF preview helps you validate scope, assumptions, and the plan logic before checkout. It’s the fastest way to prevent a bad final deliverable caused by missing or incorrect inputs.
Do you prepare ITD (Idaho Transportation Department) documents?
No. Auto-SWPPP does not prepare ITD documents or ITD-specific deliverables. If your project requires ITD-specific formats or forms, you’ll need an ITD-qualified process outside Auto-SWPPP.
Does “~24 hours” mean every project is delivered in a day?
No — it’s a target for straightforward projects with clean inputs. Complex sites (phasing, sensitive waters, dewatering, tight urban constraints) usually require more iteration and take longer.
