Under the Clean Water Act, Congress passed legislation to maintain and restore the chemical, physical, and biological integrity of the water of the United States. The objective of this study is to determine if the wooded area located in Upjohn Company's Property in southeastern Portage Township, Portage, Michigan falls under the classification of a wetland.

This objective has been pursued through an examination of the hydrology of the area, the soil characteristics of the area, and the vegetation types and characteristics of the area. These parameters have been utilized following the guidelines outlined in the "Corps of Engineers Wetland Delineation Manual." This manual provides technical guidelines for identifying wetlands, from aquatic habitats to other nonwetland areas.

The results of the data analysis showed that this area does not fulfill the hydrologic requirements for classification as a wetland as outlined by the Corps of Engineers.
