2515 North Shore Drive, Orono MN Wetland Delineation Report <br /> <br />4 <br /> <br />The site consisted of a single-family home, a driveway, and a wetland. Topography was highest <br />near the home (952 ft MSL) and from there sloped downhill to the south to Lake Minnetonka <br />(926 ft MSL) and downhill to the north to Wetland 1 (932 ft MSL). Surrounding land use <br />consisted of single-family homes and wetlands. <br /> <br />One (1) wetland was delineated within the site boundaries. The delineated wetland boundary and <br />existing conditions are shown in Figure 2. <br /> <br />Appendix A of this report includes a Joint Application Form for Activities Affecting Water <br />Resources in Minnesota, which is submitted to the Minnehaha Creek Watershed District <br />(MCWD) in request for a wetland boundary and type determination under the Minnesota <br />Wetland Conservation Act (WCA). <br /> <br />3. METHODS <br /> <br />3.1 Wetland Delineation <br />Wetlands were identified using the Routine Determination method described in the Corps of <br />Engineers Wetlands Delineation Manual (Waterways Experiment Station, 1987) and the <br />Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Midwest region <br />required under Section 404 of the Clean Water Act and the Minnesota Wetland Conservation <br />Act. <br /> <br />Wetland boundaries were identified as the upper-most extent of wetland that met criteria for <br />hydric soils, hydrophytic vegetation, and wetland hydrology. Wetland-upland boundaries were <br />marked with pin flags that were located using Trimble R1 GNSS GPS Units. <br /> <br />Soils, vegetation, and hydrology were documented at a representative location along the wetland- <br />upland boundary. Plant species dominance was estimated based on the percent aerial or basal <br />coverage visually estimated within a 30-foot radius for trees and vines, a 15-foot radius for the <br />shrub layer, and a 5-foot radius for the herbaceous layer within the community type sampled. <br /> <br />Soils were characterized to a minimum depth of 24 inches (unless otherwise noted) using a <br />Munsell Soil Color Book and standard soil texturing methodology. Hydric soil indicators used <br />are from Field Indicators of Hydric Soils in the United States (USDA Natural Resources <br />Conservation Service (NRCS) in cooperation with the National Technical Committee for Hydric <br />Soils, Version 8.2, 2018). <br /> <br />Mapped soils are separated into five classes based on the composition of hydric components and <br />the Hydric Rating by Map Unit color classes utilized on Web Soil Survey. The five classes <br />include Hydric (100 percent hydric components), Predominantly Hydric (66 to 99 percent hydric <br />components), Partially Hydric (33 to 65 percent hydric components), Predominantly Non-Hydric <br />(1 to 32 percent hydric components), and Non-Hydric (less than one percent hydric components). <br />Plants were identified using standard regional plant keys. Taxonomy and indicator status of plant <br />species was taken from the 2020 National Wetland Plant List (U.S. Army Corps of Engineers
