Create a field-ready Stormwater Pollution Prevention Plan for review, signature, and submission, built to Tennessee's Construction General Permit (TNR100000) and TDEC requirements. Whether you are a contractor, builder, developer, engineer, or handling your own site, get a compliant plan in minutes, not weeks. No engineer required for eligible non-engineered sites, and a faster starting point for the professionals who prepare them.
Who this is for: contractors, builders, developers, owners, and engineers who need an eligible Tennessee SWPPP or a single-family residential CN-1249 package. Projects with sediment basins, engineered controls, stream or wetland impacts, impaired waters, large drainage areas, or local sealed-plan requirements may need approved plans or engineer review, and the quiz and forms will flag this.
Maximum Clean Water Act civil penalty, per day, per violation. Stormwater enforcement on construction sites continues to increase.
Inspections the permit requires during construction, plus within 24 hours of any 0.5 inch storm.

What you get
Most "SWPPP generators" give you a fillable form. SWPPP Builder produces a fully written package, with narratives and BMP descriptions populated from your actual project data.
The proposed construction activity consists of site grading, utility installation, and foundation work for a commercial development located at 4821 Ridgeline Blvd, Nashville, TN 37210. The project will disturb approximately 4.7 acres of a 6.2-acre parcel. Pre-development land use is undeveloped grassland with moderate slopes (2–8%). Post-development impervious cover will be approximately 68%...
| BMP | Install trigger | Responsible party |
|---|---|---|
| Stabilized construction exit | Before any land disturbance | Site contractor |
| Silt fence (perimeter) | Before upslope grading | Site contractor |
| Inlet protection | As inlets become active | Site contractor |
Section 6 - Inspections: Inspect all controls at least twice per calendar week (at least 72 hours apart) and within 24 hours of any storm of 0.5 inch or greater, per TDEC permit TNR100000.

Straight talk
SWPPP Builder is built for eligible non-engineered contractor SWPPPs, approved-plan packages, and single-family CN-1249 lots. If your project involves any of the following, you may need engineer-stamped plans or professional review - and that's a good thing to know before you build, not after an inspection:
The quiz and the forms flag these as you go, so you're routed to the right path - or told when to bring in an engineer.
Working engineers use it too. Many use SWPPP Builder to draft routine Tennessee plans in minutes, then review, adjust, and seal them with their own judgment. The tool handles the assembly; your professional review is exactly what it is built to support.
