Will the generated plan satisfy my county?

We cannot say. It follows the federal contents list and carries your state's clause; whether your county wants something else is a question for your county.

Why not scan local rules too?

There are thousands of them and they change constantly. Claiming coverage we cannot maintain would be worse than saying plainly where the line is.

Do county or city rules apply on top of the state SWPPP requirement?

They can, and this site does not cover them: the scan behind every state page answered the state-level question only, so a local authority may require more even where the state permit allows a self-prepared plan.

A known gap, stated rather than hidden

Local rules were never scanned. Even in a state classified as self-serve here, an individual county or municipality can require a stamped plan, a local permit, or a different form. That is a residual risk of using this site, and it is the reason every page carries the same sentence about county and city rules.

One state makes the local layer part of the state answer: Connecticut's exemption for a 1–5 acre project depends on a municipal land-use commission issuing a written approval.

What to do about it

Ask the authority that will receive your paperwork, before you write the plan rather than after. It is one phone call and it is the cheapest step in the process.

The states this question turns on

Connecticut SWPPP requirements — Connecticut normally requires a licensed professional engineer or landscape architect to certify the plan, but a 1–5 acre project approved in writing by a municipal land-use commission is exempt from state review.
Texas SWPPP requirements — Texas requires the SWP3 to be developed and implemented by the primary operator; the permit contains no PE, CPESC or licensing language for preparation.
Ohio SWPPP requirements — Ohio asks for a "professional experienced in the design and implementation" of erosion and sediment controls but names no licence, exam or issuing body, and applies the same clause to 1–5 acre sites. The gate scan's summary table counts Ohio as C; the "experienced professional" wording reads as B2 in its per-state row — self-preparation is allowed either way.

What we are, and what stays your responsibility

SwpppDraft is a document generation tool. It does not provide engineering services, legal services, or compliance consulting, and no engineer or attorney reviews what it produces.
Everything in the document is built from the site facts you enter. Checking that those facts are right, and that the resulting plan fits your project, is yours to do.
We do not file anything on your behalf, we do not certify or endorse your compliance, and we accept no liability for what happens when you use the document.
State-level requirements carry the date we verified them. County and city rules are not covered — some local jurisdictions require a licensed preparer even where the state does not, and you have to check that yourself.
When the product opens, our total liability will be capped at the amount you paid us. Today that amount is zero, because nothing is for sale.
