WETLAND DELINEATION SUMMARY • The 3.74-acre site encompassing 3740 & 3760 Togo Rd was inspected on April 15th, 2024 for the presence and extent of wetland. • The National Wetlands Inventory (NWI) map showed one PEM1C wetland in the northeast portion of the site and continuing offsite. • The soil survey showed Muskego-Houghton complex as Hydric/Predominantly Hydric soil in the northeast portion of the site, corresponding to Wetland 1. Other soils mapped within the boundaries were Non-Hydric/Predominantly Non-Hydric. • The DNR Public Waters Inventory showed Minnetonka-West Arm (27-133-14 P) approximately 530 ft north of the site, and Minnetonka-Crystal Bay (27-133-10 P) approximately 800 ft to the northeast of the site boundary. An unnamed Public Wetland (27-915 W) corresponding to Wetland 1was located within the site. No Public Watercourses were mapped within 1000 ft of the site boundary. • The National Hydrography Dataset showed two Lake/Pond surface water features corresponding to DNR Public Waters to the north of the site. An artificial path and two hydro junctions are also seen running between the surface water features. • One (1) wetlands was delineated onsite as summarized in Table 1 below. Table 1.

OVERVIEW The 3.74-acre site a encompassing 3740 & 3760 Togo Rd was inspected on April 15th, 2024 for the presence and extent of wetland. The property was located in Section 17, Township 117 North, Range 23 West, City of Orono, Hennepin County, Minnesota. The site was located approximately 230 ft south of Sunset Drive/CR 51, 570 ft west of Shadywood Road/CR 19, and adjacent to and north of Togo Road (Figure 1). The property corresponded to Hennepin County PIDs 1711723310023 (3740 Togo Road; 2.37 deed acres) and 1711723310022 (3760 Togo Road; 1.37 deed acres). The site consisted of wetland, deciduous forest, and turf grass. Dominant species present within the wetland consisted of narrowleaf cattail, reed canary grass, and lake sedge. Dominant species in the forested areas of the property included cottonwood, black ash, pin oak, honeysuckle, and Virginia waterleaf. The site had mostly gentle sloping topography, with steeper slopes on the wetland’s edge. Elevations peaked at 950-ft MSL in the southwest portion of the western property, and fell to 932-ft MSL at Wetland 1 in the eastern property. Surrounding land use consisted of residential properties. One (1) wetland was delineated within the site boundaries. The delineated wetland boundaries and existing conditions are shown in Figure 2. Appendix A of this report includes a Joint Application Form for Activities Affecting Water Resources in Minnesota, which is submitted in request for a wetland boundary and type determination from the Minnehaha Creek Watershed District under the Minnesota Wetland Conservation Act (WCA). 3. METHODS Wetlands were identified using the Routine Determination method described in the Corps of Engineers Wetlands Delineation Manual (Waterways Experiment Station, 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Midwest Region (Version 2.0) as required under Section 404 of the Clean Water Act and the Minnesota Wetland Conservation Act. Wetland boundaries were identified as the upper-most extent of wetland that met criteria for hydric soils, hydrophytic vegetation, and wetland hydrology. Wetland-upland boundaries were marked with pin flags that were located with a sub-meter accuracy GPS unit. Figure 2 does not constitute an official survey product. Soils, vegetation, and hydrology were documented at a representative location along the wetland- upland boundary. Plant species dominance was estimated based on the percent aerial or basal coverage visually estimated within a 30-foot radius for trees and vines, a 15-foot radius for the shrub layer, and a 5-foot radius for the herbaceous layer within the community type sampled. 3740 & 3760 Togo Rd, City of Orono Wetland Delineation Report 4 Soils were characterized to a minimum depth of 24 inches (unless otherwise noted) using a Munsell Soil Color Book and standard soil texturing methodology. Hydric soil indicators used are from Field Indicators of Hydric Soils in the United States (USDA Natural Resources Conservation Service (NRCS) in cooperation with the National Technical Committee for Hydric Soils, Version 8.1, 2017). Mapped soils are separated into five classes based on the composition of hydric components and the Hydric Rating by Map Unit color classes utilized on Web Soil Survey. The five classes include Hydric (100 percent hydric components), Predominantly Hydric (66 to 99 percent hydric components), Partially Hydric (33 to 65 percent hydric components), Predominantly Non-Hydric (1 to 32 percent hydric components), and Non-Hydric (less than one percent hydric components). Plants were identified using standard regional plant keys. Taxonomy and indicator status of plant species was taken from the 2018 National Wetland Plant List (U.S. Army Corps of Engineers 2018. National Wetland Plant List, version 3.3, Engineer Research and Development Center, Cold Regions Research and Engineering Laboratory, Hanover, NH). 4. RESULTS 4.1 Review of NWI, Soils, Public Waters, and NHD Information The National Wetlands Inventory (NWI) (Minnesota Geospatial Commons 2009-2014 and U.S. Fish and Wildlife Service) one PEM1C wetland in the northeast portion of the site (Figure 3). The Soil Survey (USDA NRCS 2015) showed Muskego-Houghton complex as Hydric/Predominantly Hydric soils in the northeast portion of the site, corresponding to Wetland 1. Other soils mapped within the boundaries were Non-Hydric/Predominantly Non-Hydric. Soil types mapped on the property are listed in Table 2 and a map showing soil types is included in Figure 4. Table 2: Soil types mapped on the 3740 & 3760 Togo Rd site.

An unnamed Public Wetland (27-915 W) corresponding to Wetland 1was located within the site. No Public Watercourses were mapped within 1000 ft of the site boundary (Figure 5). The National Hydrography Dataset (U.S. Geological Survey 2015) showed two Lake/Pond surface water features corresponding to DNR Public Waters to the north of the site. An artificial path and two hydro junctions are also seen running between the surface water features (Figure 6). 4.2 Wetland Determinations and Delineations Potential wetlands were evaluated during field observations on April 15, 2024. One wetland were identified and delineated on the property. Corresponding data forms are included in Appendix B. The following descriptions of the wetland and its adjacent upland reflects conditions observed at the time of the field visit. The field visit took place at the beginning of the growing season. Most vegetation was identifiable from the previous season. New cool season species were growing and leaf buds on shrubs were present. Precipitation conditions were atypical (dry) using the three-month antecedent precipitation data method for a date of April 1, and typical (normal) for a date of May 1. The 30-day rolling precipitation total was within the normal range (Appendix C). In the week leading up to the observation date, there was a 0.52 inch precipitation event on April 8th and a 0.11 inch precipitation event on April 9th. Wetland 1 was a Type 3 (PEM1C) shallow marsh that was dominated by narrowleaf cattail with scattered reed canary grass and lake sedge along edges. Free water was observed at 6 inches below the soil surface in the sample borehole. Two secondary indicators of geomorphic position and the FAC neutral test were also present. The adjacent upland at the sample point location was dominated by cottonwood, red maple, and black walnut trees. No primary or secondary indicators of hydrology were observed in the upland. The wetland boundary corresponded to an abrupt change in topography, changes from hydrophytic vegetation to upland vegetation, and changes from hydric soils to upland soils. Wetland 1 corresponded to DNR Public Wetland (27-915 W) was identified on the NWI map as a PEM1C wetland and was mapped within Hydric soils (Muskego-Houghton complex) according to the soil survey. Wetland 1 extended offsite top the east and north. 3740 & 3760 Togo Rd, City of Orono Wetland Delineation Report 6 4.3 Other Areas There were no other depressional areas with hydrophytic vegetation on the site. No other areas were shown as hydric soil on the soil survey or as wetland on the NWI map. 4.4 Request for Wetland Boundary and Jurisdictional Determination Appendix A of this report includes a Joint Application Form for Activities Affecting Water Resources in Minnesota, which is submitted in request for a wetland boundary and type determination from the Minnehaha Creek Watershed District under the Minnesota Wetland Conservation Act (WCA). 5.
