How long will it take? Depending on the size of the site and potential wetland or poorly drained areas to evaluate, it can take 1-2 days to review and obtain the desktop research materials, and 1-2 field days to gather necessary site data (this timeline could be longer for more larger/more complex sites).

Delineation is an act of locating the boundary or border of a wetland or watercourse. Delineation also includes providing a geographical location in the landscape as well describes the functions and values the wetland or watercourse.

What is wetland delineation? Wetland delineation establishes the existence (location) and physical limits (size) of a wetland for purposes of federal, state, and local regulations. Wetland delineation is also an element of a jurisdictional determination.

Wetland—Land that (1) has a predominance of hydric soils; (2) is inundated or saturated by surface or groundwater at a fre- quency and duration sufficient to support a prevalence of hydrophytic vegetation typically adapted for life in saturated soil con- ditions; and (3) under normal circumstances does support a ...

Identification of wetlands using the federal delineation method primarily involves the determination of three factors: the predominance of wetland vegetation, hydric (wetland) soils, and signs of hydrology.

Indicator 2: Dominance Test. The “50/20 rule”: ▪ More than 50 percent of the dominant plant species across all strata are rated OBL, FACW, or FAC.

Three categories of wetland indicators — vegetation, soil, and hydrology — are explained briefly in the following sections.

A wetland delineation report includes the delineation methods, findings, photographs, results, soils, hydrology and vegetation data, climate conditions during the survey, and other relevant information that supports the delineator's decision on where the water body/ upland boundary is.
