WISCHMEIER PROPERTY BACKGROUND 8�METHODOLOGY <br /> Backqround <br /> As requested by Kuhl Design+Build, Anderson Engineering of MN, LLC completed a wetland investigation <br /> at the specified project area located at 540 Big Island, in the City of Orono, Minnesota. Geographically, the <br /> sites are located in Section 23, Township 117 North, Range 23 West. <br /> The wetland delineation was completed in accordance with the 1987 United States Army Corps of Engineers <br /> Wetland Delineation Manual and the published regional supplement to the Army Corps Wetland Delineation <br /> Manual, Midwest Region. <br /> The purpose of this study was to investigate the project area, identify areas meeting the technical criteria for <br /> wetlands, delineate the jurisdictional extent of the wetland, and classify the wetland habitat. <br /> Fieldwork for this site investigation was completed by Environmental Scientist Ben Hodapp&Environmental <br /> Associate Tina Justen on May 9, 2017. The weather was partly cloudy with a temperature of 71 degrees <br /> Fahrenheit. <br /> Methodoloav <br /> United States Geologic Service 7.5"Topographic Quadrangle maps, United States Fish and Wildlife Service <br /> National Wetland Inventory maps, United States Department of Agriculture Natural Resources Conservation <br /> Service Soil Survey and available aerial photographs were consulted to initially locate potential wetland <br /> habitats. <br /> Routine On-site Determination Method was used during this investigation. In this method, the following <br /> procedures were used: <br /> 1) The vegetative community was sampled in all present strata to determine whether it met hydrophytic <br /> vegetation criteria based on the indicators identified in the Midwest Regional Supplement. <br /> 2) Soil pits were dug using a Dutch auger to depths of at least 24". Soil profile was noted, in addition <br /> to any hydric soil characteristics. <br /> 3) Signs of wetland hydrology were noted and compared to field criteria such as depth to shallow water <br /> table and depth of soil saturation found in the soil pits. <br /> Data from sample points were recorded on Army Corps of Engineers Midwest Region Wetland Determination <br /> Data Forms (Appendix 8). At least one sample point transect crosses the delineated wetland edge. This <br /> transect consist of an upland sample point and a wetland sample point. Other sample points may be located <br /> in areas which have one or more of the wetland vegetation, soils, or hydrologic characteristics present; <br /> where questionable conditions exist;or to verify the absence of wetland criteria. Photographs are also taken <br /> at each sample point, and of the wetland and upland buffer(Appendix C). <br /> Sample points were marked in the field with orange flags.The identified wetland boundary was marked with <br /> sequentially numbered pink flags. All sample points and the delineated wetland boundary were located <br /> utilizing a Trimble Geo XH sub-meter GPS unit. <br /> WETLAND ASSESSMENT <br /> 540 BIG ISLAND <br /> ORONo,MN <br /> MAY 2017 <br />
