Consultants charge $1,500 to $5,000 or more to prepare one. Here is the honest, itemized breakdown of what a Tennessee SWPPP really costs, and where you can save.
A Tennessee SWPPP prepared by a consultant typically costs $1,500 to $5,000 or more. SWPPP Builder generates the same TDEC-compliant plan for a flat $349 for a standard non-engineered contractor SWPPP, $99 for a single-family homebuilder plan, or $499 when your site needs engineered or pre-approved plans. Separately, a state permit fee is paid to TDEC based on your disturbed acreage, and that fee applies no matter who prepares your plan.
Answer a few questions about your site and get a field-ready SWPPP built to TDEC permit TNR100000, at a flat, posted price. No quote calls, no waiting.
Get startedMost "how much is a SWPPP" confusion comes from bundling three separate things into one number. They are not the same, and only the first is what you are really shopping for:
So when a consultant quotes you a number, ask what it includes. Some quote only the document; others bundle NOI filing and an inspection retainer, which is why quotes are hard to compare.
An environmental or civil consultant preparing a Tennessee SWPPP generally falls in the $1,500 to $5,000 or more range for the document, with larger, more complex, or engineered sites at the higher end. You are paying for a professional's time: a site review, a custom-drafted plan, and their stamp of experience. For a complicated site, that hands-on judgment is worth it. The trade-offs are cost, turnaround measured in days to weeks, and that you are paying that fee again on the next project.
| Traditional consultant | SWPPP Builder | |
|---|---|---|
| Document preparation | $1,500 to $5,000+ | $349 standard, $99 homebuilder, $499 engineered |
| Turnaround | Days to weeks | About an hour |
| Revisions | Often billed hourly | Included; edit and reuse anytime |
| State permit fee (TDEC) | Separate, acreage-based | Separate, acreage-based |
| Field inspections | Sometimes bundled (added cost) | Arranged separately by you |
| Pricing | Usually by quote | Flat and posted up front |
Your purchase gets you the complete, site-specific SWPPP written to permit TNR100000, with the TDEC forms your reviewer and inspector expect (including the CN-1173 inspection certification and your inspection schedule), ready to review, sign, and file. You keep the file in your account to reuse and update as the job changes. To be clear about what it is not: it does not pay your state permit fee, and it does not perform your physical field inspections, those are separate costs on any project, with any provider.
Be honest about your site. If it is large, unusually complex, discharges toward sensitive or impaired waters, or needs engineered controls, a consultant's hands-on judgment (or our $499 engineered tier) is the safer path. If it is a typical site where you want a compliant plan fast and do not want to pay four figures for a document, the self-serve tool is built exactly for you. Either way, you should understand what you are getting, which is the point of posting real prices instead of hiding them behind a quote call.
Because the price is flat, there is nothing to quote. Pick your project type, answer a few questions about the site, and you will see the number before you commit. Local permit fees vary by county, so it is also worth checking your local program, our Davidson, Williamson, and Rutherford guides cover the biggest markets.
A Tennessee SWPPP prepared by a consultant typically costs $1,500 to $5,000 or more for the document. SWPPP Builder generates a TDEC-compliant plan for a flat $349 for a standard contractor SWPPP, $99 for a single-family homebuilder plan, or $499 for engineered or pre-approved-plan sites. A separate state permit fee, based on disturbed acreage, is paid to TDEC regardless of who prepares the plan.
No. The state permit fee is charged by TDEC when you file your Notice of Intent in MyTDEC, is based on your total disturbed acreage, and is paid directly to the state. It applies no matter who prepares your SWPPP, so it is separate from both a consultant's fee and SWPPP Builder's price.
A consultant's fee pays for a professional's per-project time. SWPPP Builder is self-serve and built by a licensed professional engineer, so there is no hourly consulting time to bill. You do the site-specific inputs, and the tool assembles a plan written to the current TDEC permit.
Yes. The Construction General Permit requires twice-weekly and post-storm inspections by a certified inspector once construction begins. That is a separate, ongoing cost on any project regardless of who prepared the SWPPP. The plan includes your inspection schedule and the CN-1173 form, but you arrange the inspections themselves.
You keep the file in your account to view, edit, and reuse. Each site needs its own site-specific plan, but starting from a saved project is far faster and cheaper than paying a fresh consulting fee every time.
