Wetlands must have three specific criteria in order to be classified as a wetland: hydric soils, hydrophytic vegetation, and hydrology. During a wetland delineation, a project area is surveyed to determine whether wetlands with the three criteria are present.

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.

Wetland delineation should result in three things: A wetland boundary clearly marked in the field. A map that clearly identifies data-collection points and the boundaries of the delineated wetland (topographic and aerial site maps are very helpful).
