Wetland Delineation Report <br /> Stonegate Farm,Orono& Medina, MN <br /> BES Project No. 2015-021 <br /> September 18,2015 <br /> reviewed but precipitation data could not be correlated to the photos. This is the methodology <br /> currently used to determine wetlands by both the U.S. Army Corps of Engineers for <br /> implementation of Section 404 of the Clean Water Act and by the Minnesota Wetland <br /> Conservation Act. Additionally BES conducted several site visits throughout the growing <br /> season to assess crop status in the potential farmed wetland areas. According to the <br /> Climatology Working Groups'webpage, the area was at 90-100% of average year to date <br /> precipitation at the time of the first site visit. By the August site visit the area was at 110-125% <br /> of average year to date precipitation. This is considered within the range of normal seasonal <br /> precipitation. <br /> Results <br /> Farmed Wetland Review <br /> BES' review of Farm Services Agency (FSA)annual slides are summarized in Table 1 below. <br /> Annual FSA slide for most years 1981 through 2002 were available in electronic format from the <br /> Natural Resource Conservation Service and additional aerials from 1991 to 2014 were gathered <br /> from other online sources. Early season photos and duplicate photos in the same year <br /> considered in determining the extent and location of the wetlands but were not used in the <br /> calculation of number of years with wetland signatures. Precipitation levels (Wet, Normal, Dry) <br /> were generated based on the Minnesota Climatology Working Group's "Wetland Delineation <br /> Precipitation Data Retrieval from a Gridded Database"for this specific site. The three months <br /> prior to the date of the aerial photo were used to make the precipitation level determination. <br /> The following notations were used in interpreting wetness signatures on the FSA slides: <br /> W-wet: Outline of the wetland in question can readily be seen and photographic signatures are <br /> caused by wetness. <br /> • CS-crop stress <br /> • WS-wetland signature <br /> � • DO-drowned out <br /> • NC-not cropped <br /> • SW-standing water <br /> • AP-altered cropping pattern <br /> D-dry: Outline of wetland in question cannot readily be seen. Photographic signatures are not <br /> due to wetness and are due to soil or other factors. <br /> • NV-normal vegetation cover, cropped site is tilled and planted, appears similar to <br /> surrounding fields <br /> • DNC-not cropped <br /> • D?-something is evident in the photo, but it is not necessarily due to wetness <br /> 2 <br />
