Surface ( )F6 Geomorphic Position ((D2) Wetland Type PEM 1 A The NWI Cowardin wetland classification system identifies the PEM1Alabel for awetland that consists of a palustrine basin, dominated by persistent emergent vegetation, consisting of erect, rooted, herbaceous hydrophyte species that normally remain standing at least until the beginning of the next growing season, that is temporarily flooded. Surface water is present for brief periods during the growing season, but the water table usually lies well below the ground surface for most of the season. The NWI map for the Site area indicated two PEM 1 A wetlands, including one isolated wetland located in the west central portion of the Site, in the location of Suspect Area-1 (SA-1), and the other located in the southern portion of Wetland 1. The soils survey did not indicate hydric soils located within the SA-1 aera. The soil survey indicated hydric soils were present in the area of Wetland 1. The SA-1 area is most likely an excavated infiltration pond with a large culvert draining into it. Wetland Type PEM1C The NWI Cowardin wetland classification system identifies the PEM 1 C label for a wetland that consists of a palustrine basin, dominated by persistent emergent vegetation, consisting of erect, rooted, herbaceous hydrophyte species that normally remain standing at least until the beginning of the next growing season, that is seasonally flooded. Surface water is present for extended periods especially early in the growing season but is absent by the end of the growing season in most years. The water table, after flooding ceases, is variable, extending from saturated to the surface to a water table well below the ground surface. The NWI map for the Site area indicated two PEM 1 C wetlands contained within the Site boundaries. One of the these depicted areas corresponds to the northern portion of Wetland 1 and the other corresponds to the fringe of Wetland 2. The soils survey did Pinnacle Engineering, Inc.
