USACE Wetland Permit Geofence Watcher

Monitor public USACE wetland and Clean Water Act public notices for projects near watched sites, watersheds, counties, applicants, and comment deadlines.

This Actor turns the public USACE Regulatory Request System public-notice feed into normalized events that are easier for due-diligence tools, land teams, environmental consultants, legal teams, lenders, and AI agents to consume.

What It Does

• Searches the public USACE RRS public-notice API.
• Fetches each notice detail before emitting results.
• Matches notices against watched geofences, states, districts, counties, HUC codes, applicants, action types, and project terms.
• Emits deterministic comment-deadline alerts for notices accepting public comments.
• Includes source links and API provenance on every record.
• Deduplicates repeated runs with a named key-value store.

Inputs

Input	Purpose
searchText	Text sent to the RRS search endpoint. Default is wetland; set an empty string to search all active public notices.
geofences	Up to 10 { lat, lon, radiusKm, label } circles.
states	Two-letter state filters.
districtCodes	USACE district code filters such as SAJ or NAO.
counties	County names or fragments.
hucCodes	HUC prefixes or full HUC codes.
actionTypes	Exact action types such as SP or DEVMBA.
applicantKeywords	Word-boundary applicant/company terms.
projectKeywords	Word-boundary project, keyword, or description terms.
dateWindow	Public-notice-start date window. Default is 30 days.
commentWindowDays	Emits deadline alerts for matched notices closing within this many days.

Output Events

Event	When It Emits
geofence_public_notice_match	A public notice falls inside a watched geofence after filters.
new_public_notice	A public notice matches non-geofence filters, or no geofence is supplied.
comment_deadline_alert	A matched accepting-comments notice closes within commentWindowDays.

Every event includes:

• source_notice_url
• source_api_url
• entities with DA number, district, action type, applicant, HUC, county, and state
• dates with public notice start, comments end, and days remaining
• location with latitude, longitude, and coordinates_basis
• matched_geofences
• matched_dimensions
• match_terms
• raw source notice payload

Pricing

Pay per event:

• geofence_public_notice_match: $0.06
• new_public_notice: $0.04
• comment_deadline_alert: $0.03

No events are charged for unmatched source records, duplicate events, or empty runs.

Limitations

• This Actor uses public USACE RRS JSON endpoints. It is not affiliated with USACE.
• Coordinates are source-provided and may be sparse or approximate. Check coordinates_basis.
• Public notice links may point to district pages or PDFs maintained outside RRS.
• The default search text is wetland; set it to an empty string to search all active public notices.
• This is an informational monitoring feed, not wetland delineation, environmental, legal, permitting, lending, or compliance advice.

Maintenance

The live canary searches wetland, fetches detail records, and verifies DA numbers, comment dates, coordinates, and provenance. If the RRS API changes shape or starts returning an access page, the canary fails loudly so the maintainer can patch or pause the Actor.
