The presence of these three criteria may be directly observed or inferred by examining indicators of the criteria. For example, standing water may not be present on a site at the time of an environmental survey, but water stains which are located two feet from the base of the trees is a strong indicator that water was present at some time in the past. The presence of water-stained trees, drift lines and sediment deposits are examples of accepted indicators that would positively indicate that the area meets the wetland hydrology criteria.

A wetland delineation is simply the determination of whether an area is defined as a wetland and where the wetland line is. Confirming the presence or absence of wetlands and their exact location is often the first step in determining if a property is developable or in determining how to proceed with development plans to minimize overall development costs.

FELSI's wetland scientists have been formerly educated or received supplemental training in botany, state- and federally-approved wetland delineation methodologies and soil science and will use this training to conduct a wetland delineation to determine and document where the site-specific wetland limits are located. The wetland line will be saved electronically using Global Positioning System. FELSI will provide you with a wetland delineation report which consists of a map of the wetland limits, written descriptions of the wetland communities and site photographs.
