V. FINDINGS In September of 2022 a field investigation was perfoinied to evaluate and verify the existence and boundary of any aquatic resources located within the study area. Eight wetlands were found to exist within the study area. The following describes the aquatic resources identified, together with a brief description of wetland types and observations made during the field investigation. Wetland 1 (W1): NWI Cowardin: PEM1A PWI (Hydro) ID: None Field Observation Circular 39: Type 2 Field Observation Eggers and Reed: Fresh (wet) Meadow Soil Mapping Unit(s): Duelm loamy sand/Hubbard loamy sand/Isan sandy loam Wetland 1 is located in the northwest corner of the study area. Wetland 1 is believed to be a historical wetland. The field investigation found the site has met all three wetland indicators and this wetland should be considered palustrine emergent persistent seasonally saturated (PEMIB) wetland. One transect and several sample points were taken to deteiniine the wetland boundary. Soils, hydrology and topography aided in deteiniining the wetland boundary. At the wetland pit location W IA the plant community is dominated by reed canary grass and quaking aspen. The upland pit location W IB is dominated by smooth brome, reed canary grass, and quaking aspen. Both plant communities are considered hydrophytic. Soils in the wetland pit location W IA were marked as Other and assumed to meet a hydric soil indicator below the thick dark surface. Soils in the upland pit location W IB did not meet any hydric soil indicators. WZ Soils in the wetland pit W IA were not saturated. The pit location met secondary hydrology indicators D2 — Geomorphic Position and D5 — FAC-Neutral Test. Soils in the upland pit location WIB were not saturated and did not meet any hydrology indicators. The deteiniining factor for this delineation was the lack of hydric soil and wetland hydrology indicators at the upland pit location. The boundaries were deteiniined by following the topographic breaks. Wetland 2 (W2): NWI Cowardin: PSSIA/PUBH PWI (Hydro) ID: None Field Observation Circular 39: Type 4/7 Field Observation Eggers and Reed: Deep Marsh/Wooded Swamp Soil Mapping Unit(s): Duelm loamy sand/Hubbard loamy sand Wetland 2 is located in the northeast part of the study area, just to the east of Wetland 1. A portion of W2 is believed to be historical with the other portion being a pond excavated in upland. The field investigation found the site has met all three wetland indicators and this portion of the wetland should be considered a palustrine emergent semipeiuianently flooded/palustrine forested Prepared by: Bolton & Menk, Inc.
