Wetland Delineation Report Ramsey Station November 25, 2002 — Revised March 14, 2003 LAND USES AND EXISTING SOIL CONDITIONS: The site consists of two different types of land uses: 1) agricultural production, and 2) wetlands. Table 1 outlines an estimated acreage of the land types observed in the field: Table 1: Estimated Acreage of Project Site Land Use Approximate Acreage Percentage Agricultural Production 270.67 acres 95.5 % Wetlands 8.13 acres 4.5 % TOTAL 275 acres 100% Below is a description of the land types during 2002. AGRICULTURAL PRODUCTION — The property is currently in soybean and corn row crops. Crops were harvested in October and November of 2002. Corn and soybeans have been rotated throughout the years. WETLANDS — Four wetlands were located on the site. The wetlands are Types 2 (wet meadow), Type 3 (shallow marsh) and Type 4 (shallow open water). Hydrology from the area has been modified in the past leading to wetland conditions observed in 2002. Wetland hydrology is supplied through natural drainage patterns creating isolated wetland basins. Refer to Appendix C for photos of wetland areas. Below are brief descriptions of the wetlands delineated on- site. Wetland A — Wetland A is an isolated wetland basin that consists of type 2 and Type 3 wetland vegetation. The open water in Wetland A existed in 1981 and a ditch was dug in 1982 to facilitate drainage. Spoil was cast on the south side of the wetland and is visible in the aerial photos. Dominant wetland vegetation includes Typha angustifolia (narrow leaved cattail), Scirpus fluviatilis (river bulrush), Phalaris arundinacea (reedcanary grass), Verbena hastata (Blue vervain) and Solidago gigantea (Giant goldenrod). Wetland B — Wetland B is an isolated wetland basin excavated in 1999 for the County Road 116 road project. The wetland consists of Types 2, 3, and 4 wetland vegetation. Wetland B was created as a mitigation site for the construction of the County Road 116 extension project completed in 1999. Dominant wetland vegetation includes Typha angustifolia (narrow leaved cattail), Scirpus fluviatilis (river bulrush), Scirpus validus (hardstem bulrush), Carex sp. (sedge) and Verbena hastata (Blue vervain). Wetland C — Wetland C is an isolated wetland basin that was likely connected hydrologically to other wetland complexes prior to County Road 83 and County Road 116 construction. Road construction bisected the wetland and may have disrupted the historical flow of hydrology. Page 2 of 52
