Overview
Draft Routine Determination wetland delineation reports, data-form support tables, aquatic resource summaries, and AJD/PJD request packages using the 1987 USACE Wetlands Delineation Manual, Regional Supplements, NWPL, hydric soil indicators, and post-Sackett WOTUS framing.
What It Covers
- Routine Determination report narrative and appendix structure
- Region-specific USACE Wetland Determination Data Form support
- Vegetation, hydric soil, and wetland hydrology evidence tables
- Stream, ditch, open-water, OHWM, and flow-regime documentation prompts
- AJD/PJD request letter and supporting documentation index
- Preliminary Section 404/401 permit-path screening with human professional review
Example Conversation
You: We delineated a 42-acre solar site in Burke County, Georgia. Fieldwork was March 18–19 using the Atlantic and Gulf Coastal Plain supplement. We have Wetland A at 0.72 acre, Wetland B at 0.18 acre, and an intermittent stream at 410 linear feet. Can you draft the report and AJD request package?
Agent: Yes. I’ll structure the report around the 1987 USACE Manual and Atlantic and Gulf Coastal Plain Regional Supplement, then separate the delineation findings from the agency jurisdictional determination. Please upload or summarize the sample point data forms, APT/WETS output, NWI/SSURGO/USGS maps, photo log, and any OHWM or flow-regime notes for the stream.
You: I have paired wetland/upland plots for each wetland and photos for the stream, but no district contact yet.
Agent: I’ll leave the USACE district contact as a verification item, draft the AJD cover letter generically for the Regulatory Division, and flag final checks for current JD forms, NWPL year, hydric soil indicator version, and district submittal instructions.
Sample Output Excerpt
Below is a short excerpt from the kind of report package the skill drafts.
Executive Summary
On March 18–19, 2026, field personnel conducted a Routine Determination wetland delineation for the approximately 42-acre Burke County Solar Study Area. The delineation was performed using the 1987 Corps of Engineers Wetlands Delineation Manual and the Atlantic and Gulf Coastal Plain Regional Supplement. Final agency jurisdiction remains subject to U.S. Army Corps of Engineers review.
The study area contains two wetland features and one intermittent stream:
| Feature | Resource Type | Area / Length | Supporting Data |
|---|---|---|---|
| Wetland A | Palustrine forested wetland | 0.72 acre | SP-1W / SP-1U, photos 3–8 |
| Wetland B | Emergent wetland | 0.18 acre | SP-2W / SP-2U, photos 9–12 |
| Stream 1 | Intermittent stream | 410 linear feet | OHWM observations, photos 13–17 |
Jurisdictional Determination Recommendation
Based on the current record, the applicant may request an Approved Jurisdictional Determination for the review area. The request package should include the report narrative, data forms, aquatic resource map, representative photographs, APT/WETS documentation, and available downstream connection evidence. The final WOTUS determination should be made by USACE.
Extension Tools
This skill does not include custom extension tools. It uses structured references and checklists to guide the agent through evidence sufficiency, report drafting, data-form support tables, and AJD/PJD package assembly.
Key built-in reference checks include:
- Required project, fieldwork, Regional Supplement, and NWPL inputs
- Vegetation, soils, hydrology, and paired upland/wetland sample-point sufficiency
- OHWM, bankfull, flow-regime, ditch, culvert, and downstream-connection documentation
- Current form/version checks for USACE district submittals, JD forms, hydric soil indicators, and Nationwide Permit terms
Getting Started
Bring the site location, study area boundary, field dates, Regional Supplement region, sample point data forms, photo log, desktop maps, precipitation normality output, and any requested AJD/PJD or permit-path goal. If you only have screening materials, the skill will produce a gap checklist instead of pretending the field delineation is complete.
