Screen a wetland or waterway impact against the nationwide permits
No account, no card, and no request. The engine that answers this is the same one behind the API and the MCP server, and it runs in this tab, so your project facts are never transmitted.

Nationwide permit, notification required
A nationwide permit looks available, but you must file a pre-construction notification before you build.
Computed against the 2026 nationwide permits, effective 2026-03-15.
Pre-construction notification
Required. The district engineer has 45 calendar days to review a complete notification.
Permanent loss is greater than 0.1 acres, which triggers a pre-construction notification.
Verified0.35 acres measured against the 0.1 acres notification trigger.

VerifiedPCN required if: (1) the loss of waters of the United States exceeds 1/10-acre; or (2) there is a discharge in a special aquatic site, including wetlands.

VerifiedRequired for activities under paragraph (b) - removal of accumulated sediments and debris outside the immediate vicinity of existing structures.

Permanent loss is within the 1/2 acre limit NWP 14 applies in non-tidal waters.
Verified0.35 acres of permanent loss in non-tidal waters, measured against the 1/2 acre limit. 1/2-acre limit applies in non-tidal waters; a lower 1/3-acre limit applies in tidal waters.

No impact limit has been transcribed for NWP 3 yet, so eligibility cannot be determined here.
UnverifiedPermitBird returns an explicit gap rather than an inferred limit. Read the permit text or contact the district office.

What we hold for this stateWhat this determination does not cover
- The mapping from "Road, highway or railway crossing" to candidate permits is unverified. Confirm the permit selection against the permit text.
- Impact limits are not yet transcribed for NWP 3.
- Regional conditions for the Sacramento District are not compiled. They can narrow or remove a nationwide permit, so confirm them with the district before relying on this.

Project impact entered: 0.35 acres permanent loss, 120 linear feet of stream bed.
Describe the impact
State, USACE district, the kind of aquatic resource affected (wetland, stream, open water or tidal), and the permanent loss in acres.
Add the activity
What kind of work it is, so the tool narrows to the nationwide permits that could actually apply rather than screening all 57 against thresholds that assume the wrong activity.
Read the determination
A candidate pathway, whether a pre-construction notification is triggered, and what still needs checking at the district and state Section 401 layers, each reason citing the rule it came from.
PermitBird reports publicly published permit rules and cites the source and effective date behind each one. It is not legal or engineering advice and it is not a permit. Section 404 determinations do not replace a jurisdictional determination or a pre-construction notification filed with the district. We do not perform wetland delineations. We do not perform the physical site inspections a stormwater permit requires; we generate the plan and keep the record. Where a jurisdiction requires a credentialed preparer, the document we generate is a draft for that person to review and sign. Always confirm against your permitting authority's current rules before you break ground.
This determination is free forever, no account
Section 404 screening never sells behind a plan. If the project also disturbs an acre or more, the stormwater side is where the paid record-keeping lives.
