3625 Jacobs Mill Road <br /> Orono, Minnesota <br /> Wetland Delineation Report <br /> I. INTRODUCTION <br /> The 3625 Jacobs Mill Road site was examined on April 12, 2012 for the presence and extent of <br /> wetland. The 7.32-acre site was located in Section 32, Township 118N, Range 23W, City of <br /> Orono,Hennepin County,Minnesota. Generally the site was located southwest of the <br /> intersection of Jacobs Mill Road and Stubbs Bay Road(Figure 1). The site was comprised of all <br /> of Hennepin County PID 32-118-23-24-0013. <br /> The site was comprised of moderately undulating Kentucky bluegrass and smooth brome <br /> dominated meadow and was vacant of buildings or other structures (Figure 2). Adjacent land <br /> use was large-lot single family homes. <br /> II. METHODS <br /> Wetlands were identified using Routine Determination methodology described in the Corps of <br /> Engineers Wetlands Delineation Manual(Waterways Experiment Station, 1987)and Regional <br /> Supplement to the Corps of Engineers Wetland Delineation Manual: Midwest Region(Version <br /> 2.0)as required by Section 404 of the Clean Water Act and the Minnesota Wetland Conservation <br /> Act. <br /> Wetland boundaries were identified as the upper-most extent of wetlands,which met criteria for <br /> hydric soils, hydrophytic vegetation, and wetland hydrology. Wetland-upland boundaries were <br /> marked with pink pin flags and located by Demars-Gabriel surveyors. <br /> Soils, vegetation, and hydrology were documented at representative locations 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, 15-foot radius for the <br /> shrub layer, and a 5-foot radius for the herbaceous layer within the community type being <br /> sampled. <br /> Soils were characterized to a minimum depth of 18-20 inches(unless otherwise noted)utilizing <br /> Munsell Soil Color Charts and standard soil texturing methodology. Hydric soil indicators used <br /> in reporting are from the NTCHS Field Indicators of Hydric Soils in the United States (USDA <br /> Natural Resources Conservation Service Version 7,2010)which are commonly found in the <br /> Midwest. <br /> 2 <br />
