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.
