What this due-diligence check covers
A qualified field delineation evaluates vegetation, soils and hydrology under applicable methods. Regulatory jurisdiction and permitting are separate determinations by relevant agencies.
State and local rules can protect areas beyond federal jurisdiction.
Why it matters before closing
Wetlands and buffers can affect building pads, roads, utilities, septic, fill, drainage and mitigation cost.
What to verify
- Screen the parcel with official mapped data.
- Overlay the proposed disturbance area.
- Walk for wetland indicators and drainage features.
- Ask qualified professionals and agencies about delineation and permits.
Red flags that deserve follow-up
- Mapped feature through the only access corridor.
- Seller claims prior approval without current documents.
- Drainage ditch assumed unregulated.
- Fill or clearing started before review.
Evidence to keep in the parcel file
- Wetlands map screen
- Field delineation report
- Agency correspondence or determination
- Permit and mitigation assumptions
Questions to ask before the deadline
- Does the project disturb wetlands or buffers?
- Is a field delineation needed?
- Which federal, state and local agencies apply?
- Can the design avoid the feature?
- What schedule and mitigation may be required?
