WETLAND DELINEATION REPORT Waunakee Veterinary Service 0 5636 County Road V Project #: 20200415 November 3, 2020 2.0 Methods 2.1 Wetlands Wetlands were determined and delineated using the criteria and methods described in the USACE Wetlands Delineation Manual, T.R. Y-87-1 ("1987 Corps Manual") and the applicable Regional Supplement to the Corps of Engineers Wetland Delineation Manual. In addition, the Guidance for Submittal of Delineation Reports to the St. Paul District USACE and the WDNR (WDNR, 2015) was followed in completing the wetland delineation and report. Determinations and delineations utilized available resources including the U.S. Geological Survey's (USGS) WI 7.5 Minute Series (Topographic) Map (Figure 2, Appendix A), the Natural Resource Conservation Service's (NRCS) Soil Survey Geographic Database (SSURGO), U.S. Department of Agriculture's (USDA) Web Soil Survey (Figure 3, Appendix A), the Wisconsin Department of Natural Resources'Surface Water Data Viewer's wetland indicator data layer (Figure 4, Appendix A), the WDNR's Wisconsin Wetland Inventory data layer (Figure 5, Appendix A), and aerial imagery available through the USDA Farm Service Agency's (FSA) National Agriculture Imagery Program (NAIP), Google EarthTM, and Dane County's interactive mapping. The USGS National Hydrography Dataset is included on Figures 2 and 5, Appendix A. Wetland determinations were completed on-site at sample points, often along transects, using the three (3) criteria (vegetation, soil, and hydrology) approach per the 1987 Corps Manual and the Regional Supplement. Procedures in these sources were followed to demonstrate that, under normal circumstances, wetlands were present or not present based on a predominance of hydrophytic vegetation, hydric soils, and wetland hydrology. In actively farmed areas within the Study Area where hydric soils may be present, methods described in Chapter 5 (Difficult Wetland Situations) of the Regional Supplement were followed. Available aerial imagery was analyzed using procedures described in the Guidance for Offsite Hydrology/Wetland Determinations (USACE and Minnesota Board of Water and Soil Resources, July 2016 — "July 2016 Guidance"). An off-site aerial imagery analysis (Off- Site Analysis) was completed to document the presence or absence of wetland signatures and assist in the wetland determination. A wetland signature is evidence, recorded by aerial imagery, of ponding, flooding, or impacts of saturation for sufficient duration to meet Solutions for people, projects, and ecological resources.
