(888) 405-1742Before we mobilize, our scientist reviews the site — the area a Wetland Screen flagged, aerial imagery, soils and hydrology data, and any prior reports — so the field visit goes straight to the parts of the property that matter. You get a clear, flat-fee quote before anyone heads out.
A scientist walks the property and checks the three regulatory parameters in the field — hydrophytic (water-loving) vegetation, wetland hydrology, and hydric soils. All three must be present for an area to be a wetland; if any one is missing, it is not. This is a focused presence/absence check, not the full boundary mapping of a Delineation.
We deliver a concise memo with the answer: wetlands are present on the property, or they are not — and, if present, whether a full Wetland Delineation is warranted to map the boundary. You get a definitive result you can act on before committing to the next, larger step.
Wetland due diligence runs in sequence — each step escalates only if the one before it warrants it. A desktop Screen flags possible wetlands anywhere in the lower 48; a Confirmation, Delineation, and Jurisdictional Determination are field-based and serve Northern Illinois and the Midwest.

A Wetland Confirmation is a focused on-site field visit that answers one question: are wetlands actually present on the property, yes or no? It is the natural next step after a Wetland Screen — a desktop review of government mapping data — has flagged that wetlands may be present. A Screen can only suggest; a Confirmation sends an environmental scientist to the property to verify in the field. It is faster and far less involved than a full Wetland Delineation, and it is the right-sized step when you need a definitive answer before deciding whether to invest in mapping the boundary.
Under the 1987 USACE Wetlands Delineation Manual and its regional supplements, an area is a wetland only if it has all three of the following: hydrophytic (water-loving) vegetation, wetland hydrology, and hydric soils. The logic is simple but strict — if any one of the three is absent, the area is not a wetland. During the site visit our scientist evaluates each parameter directly in the field, which is why a presence/absence answer requires boots on the ground rather than a map.
A Confirmation tells you whether wetlands exist on the property. It does not map where they begin and end — that is the job of a Wetland Delineation, which flags and GPS-locates the boundary and produces a full report for permitting. Think of the Confirmation as the deliberate checkpoint between a Screen and a Delineation: many clients run it first precisely to avoid paying for a full delineation on a property that, it turns out, has no wetlands at all. If wetlands are present, the Confirmation tells you a Delineation is warranted; if they are not, you have a clean answer and can move forward.
The work runs in three steps: a desktop review of the site, a scientist's site visit to check the three parameters, and a concise confirmation memo stating whether wetlands are present and whether a Delineation is warranted. The fee is $1,450* — and because this is field work, the asterisk matters: the price varies with travel time and distance, since a property that takes most of a day to reach and return from costs more than one near our office. We perform Wetland Confirmations across Northern Illinois and the Midwest, typically within about a two-hour radius of Naperville, Illinois, and will travel farther for the right client and project. A3 Environmental has served the Midwest since 2015 with a 4.9★ Google rating.
