Wes Boll, Wenck, Inc. consultants to the Minnehaha Creek Watershed District met on site with me to review two items: 1. Status of the area to the east of the residence and near the eastem boundary of the property to determine if the location (Sample Point 1_2) satisfied the wetland criteria requirements 2. Determine the status of a drainageway located on the west end of the parcel and designated as D1 With regard to Item 1, status of Sample Point 1 2, Mr. Boll and I examined the soil profile in the proximity of the same location as that for wetland delineation. He sampled to a depth of 36+"and found no evidence of wetland hydrology pr�esent despite the fact that the past 3 weeks have been relatively wet. Recent data from the National Agricultural Statistical Service(NASS)(see attachment)that tracks and publishes weekly precipitation data from a netwoiic of National Wea�er Senrice Stations across Minnesota reports that for the week ending October 27,2013,recorded precipitation for the week at the Minneapolis-St. Paul Airport was 0.6"above normal for the preceding 4 weeks and 2.56"above normal for the period beginning April 1, 2013. The Universiiy of Minnesota, St. Paul location reported 1.55" above normal for the past 4 weeks and 4.35"above normal for the period beginning April 1,2013. Other suggestive indicators of non-wetland are two of the plant species present. Bur oak, which is designated as FACU in both the Great Plains and North Central—Northeast Regions but FAC in the Midwest, was present. If the FACU indicator was used instead of FAC, it would bring the vegetation indicator closer to non-wetland.The project site is located approximately 15 miles southwest of the line defining the boundary between the Midwest Region and the North Central Northeast Region.Applying the indicator status of FACU in this case to clarify the potential status of the area would not be inappropriate. European buckthom, also present in considerable numbers in the area of Sample Point 1 2 is classified as FAC in Uie Midwest and North Central—Northeast Region while it is considered FACU in the Great Plains Region,which is considerably more distant from the site. 1
