NWI maps generally show the approximate location of wetlands as of the time of publication. 2.2.4 Public Waters Inventory The Minnesota Department of Natural Resources Public Waters Inventory (PWI) produces a map of the protected wetlands and waters of the State. The PWI map, which is included as Figure 5, identified a PWI protected basin number 02066500 within the Site. No PWI watercourses were identified within the Site boundaries. 3.0 WETLAND DETERMINATION 3.1 Methodology The wetland determination was made utilizing the techniques of the Routine Level 2 Onsite Method, as described in the 1987 U. S. Army Corps of Engineers Wetland Delineation Manual, updated February 25, 1997 and utilizing the Midwest Regional Supplement. Determination of hydric soils, site hydrology, and hydrophytic vegetation were made according to the procedures and guidelines described in the manual. Sampling locations were selected to be representative of wetland/upland transition areas. Scott Thelen of Pinnacle assessed the wetlands within the project area on July 19, 2022. The assessment included probing the soils to observe the color and moisture, as well as other available hydric soil indicators, such as mottling, gleying, and oxidized root channels. The characteristics noted for each sampling location are documented in the data forms, which are included in Appendix A. Potential wetland boundaries were collected using a handheld GPS unit and were flagged for survey by Sunde. The wetland areas are depicted on Figure 2. The wetland delineation was conducted at the beginning of the growing season with some remnant dormant vegetation present. The 2022 seasonal antecedent rainfall amounts were below the normal precipitation amounts for this area. Precipitation amounts of 0.26 inches of rain occurred the fourteen days prior to the wetland delineation field visit. Hydrology was not anticipated to be present during the field visit. 3.2 Wetland Descriptions Pinnacle identified two wetlands within the Site as depicted on Figure 2. NWI descriptions of the wetland classifications and types are found below. Table 3.2.1 below summarizes the findings of the field investigation. Data forms for the field investigation can be found in Appendix A and photographs in Appendix C. Pinnacle Engineering, Inc.
