2640 Watertown Rd Site, Orono Wetland Delineation Report 2 2. OVERVIEW The 2.3-acre 2640 Watertown Rd Site was inspected on July 13th, 2021, for the presence and extent of wetland. The property was located in Section 33, Township 118 North, Range 23 West, City of Orono, Hennepin County, Minnesota. The site was situated adjacent to the northeast side of the intersection of Golden View Drive and Watertown Road (Figure 1). The property corresponded to Hennepin County PID# 3311823430004. The 2640 Watertown Rd Site consisted of a disturbed area that was previously a house and yard, two wetlands, woodland, and a meadow/field with scattered trees and uneven topography. It is suspected that the southern third of the site, where the house and yard was, contains fill and there is also an old road bordering the eastern boundary. Topography of the site sloped from 1036 ft MSL on the southern portion of the site down to 1030 to 1032 ft MSL within the wetlands. Surrounding land use is residential. Two wetlands were delineated within the site boundaries. The delineated wetland boundaries and existing conditions are shown on Figure 2. Figure 2 does not represent an official survey. Appendix A of this report includes a Joint Application Form for Activities Affecting Water Resources in Minnesota, which is submitted in request for: (1) a wetland boundary and type determination under the Minnesota Wetland Conservation Act (WCA), and (2) delineation concurrence under Section 404 of the Federal Clean Water Act from USACE. 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 subsequently located by surveyors with Landform. 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
