MAPLE CREST LANDSCAPE BACKGROUND & METHODOLOGY <br />Background <br />As requested by Maple Crest Landscape, Anderson Engineering of MN, LLC completed a wetland <br />investigation at the specified project area located at 2709 Walters Port Lane & 2710 Pence Lane, in the City <br />of Orono, Minnesota. Geographically, the sites are located in Section 21, Township 117 North, Range 23 <br />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 Associate Tina Justen and GIS <br />Specialist Joe Aden on April 5, 2017. The weather was partly cloudy with a temperature of 50 degrees <br />Fahrenheit. <br />Methodolo <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 />2709 WALTERS PORT LANE & 2710 PENCE LANE <br />ORONO, MN <br />APRIL 2017 <br />
