4035 Dahl Road Orono, Minnesota Wetland Delineation Report I. INTRODUCTION The 1.76-acre 4035 Dahl Road Parcel was inspected on June 6, 2017 for the presence and extent of wetland. The property was located in Section 7, Township 117N,Range 23W, Orono, Hennepin County,Minnesota. Generally, the site location was south of Dahl Road and east of North Arm Drive (Figure 1). The site limits corresponded to Hennepin County PID 0711723140003. � The majority of the site was manicured lawn with scattered hardwood and evergreen trees. One single-family home was present in the eastem portion of the property. Adjacent land use was primarily single-family homes, forested area, and Lake Minnetonka. The topography was lowest near the western edge of the site with a bottom elevation of 986 feet msl(at Wetland 1) and rose in elevation to the east with a high point at 1412 feet msl. One depressional wetland was identified and delineated within the site boundaries (Figure 2). II. 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 by surveyors from Lot Surveys Company, Inc. 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. 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 percent composition of hydric components and the Hydric Rating by Map Unit color classes utilized on 2
