<br /> 2 <br />INTRODUCTION <br />Midwest Natural Resources, Inc. (MNR) was contracted by Brad & Carol Pass to provide wetland <br />delineation services for their properties located at 215 North Arm Lane and PINs 0611723240002 & <br />0611723230021 in Orono, Hennepin County, Minnesota (Appendix A, Figure 1). On April 9, 2024 <br />MNR conducted a routine wetland delineation within the site to determine any wetland boundaries. <br />In all, the boundaries of three wetlands and one linear waterbody were delineated within the site. No <br />other areas within the survey area were reviewed for the presence of wetland. <br />DESKTOP REVIEW <br />Prior to conducting the field surveys, MNR staff conducted a desktop review to evaluate existing <br />data within the project area including the following. All data are illustrated in the figures in Appendix <br />A. <br />• MN DNR Public Waters Inventory (PWI) (Figure 2) <br />• US FWS National Wetlands Inventory (NWI) (Figure 3) <br />• Hennepin County Soil Survey (Figure 4) <br />• LiDAR elevation <br />• Aerial imagery <br />• Climate data (Appendix B) <br />METHODS <br />The entire survey area was surveyed via pedestrian surveys to investigate the presence of wetlands, <br />and the potential wetland features identified in the desktop review were targeted for investigation. <br />All potential wetlands were evaluated utilizing the Routine “Onsite” Determination Method contained <br />in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Midwest Region <br />for the 1987 Wetlands Delineation Manual Technical Report Y-87-1. For each potential wetland within <br />the survey area, the three wetland parameters (vegetation, hydrology, and soils) were examined to <br />determine wetland status. If positive wetland status was determined, a sample transect was <br />established where the wetland/upland transition occurs. In each transect, the three parameters <br />(vegetation, hydrology, and soils) were documented at a sample point within the wetland and in the <br />adjacent upland. <br />Vegetation was assessed at each sample point by identifying the dominant species present and <br />noting wetland indicator status. Hydrologic indicators were evaluated for characteristics including, <br />but not limited to, the presence or absence of inundated or saturated soils, high water table, drift <br />lines, drainage patterns, and landscape position. The final parameter, soils, was assessed by digging <br />a soil pit to at least 18 inches, where feasible, and examining the soil profile for indicators of hydric <br />soils. In locations where a soil pit could not be dug due to the presence of buried utilities, soils were <br />assumed hydric or non-hydric based on the dominant vegetation and presence or absence of <br />hydrologic indicators, respectively. <br />All data and information pertaining to each wetland and upland sample point were collected using <br />the applicable Corps wetland determination forms, and representative photos of each feature <br />reviewed were collected. Wetland boundaries were recorded spatially with GPS units (Trimble GeoXT <br />6000) and were flagged in the field. Areas not meeting wetland criteria were documented with a non- <br />wetland sample point and a representative photograph. <br />174
