NOV-10-99 05 :35 PM P.03 • west property line. An open ditch that conveys water from the main basin of the wetland and into a culvert that is part of the City storm sewer system and of that drainage easement. The area along Long Lake Road is an embankment that slopes down to the wetland edge. Most of the site is wooded with Oak, Buckthorn and Boxelder trees. There were a few deep (3 or more feet) soil test holes that had been drilled on the site in upland areas. They did not exhibit wetland soil characteristics or hydrology. A path through the property appears to be used for a bicycle course by neighborhood children. The wetland is located along the north edge of the site and extends well beyond the property to the north. The preliminary determination of potential wetland edges was based onvegetation and topography. The soils were tested by digging holes to a depth of 40" using a narrow bladed shovel at upland and wetland locations. A soil probe with a 3/4" opening was also used to retrieve soil sample s for inspection. Soil colors were determined by matching them to a Munsell Soil Color Chart. The soils were examined for hydric characteristics such as: low chrome, organics, mottling, gleying, and moisture. Soil samples were observed at points inside the basins with some wetland characteristics, at the basin/wetland edge, and into the upland zones. Soil pits were marked with orange stake flags labeled "A" In the wetland, "B" near the wetland edge, and "C" in adjacent upland. Conditions at the soil pits are described on attached Data Forms. " I placed wire stakes with pink flags at the edge of the delineated wetland on this parcel. Wetland 1 is a Type 3 wetland that is mostly on the adjacent property to the north, The delineated edge of the wetland is mostly at the base of trees and shrubs. It has the ditch and culvert at the west side of this property, as described above. There are likely other culverts at the perimeter of the basin at locations beyond this property. It is a large basin with reed canary grass and willows in the basin and dogwood and jewelweed near the delineated edge, Other vegetation including woolgrass, and joe pye weed was found. There was standing water in the ditch and in pockets within the main basin. It is designated as wetland on the NWI map and the soils in the vicinity are labeled as Seelyeville muck (a hydric soil). I placed flags at the wetland edge beginning at the culvert at the south end of the open ditch, moving north along the east edge of the ditch and then east to the toe of the slope of the embankment of Long Lake Road. I have sketched and highlighted the approximate location .of the wetland onto a plat map provided by Harstad. That sketch is attached. The surveyors should prepare a scale drawing showing the location of my delineation flags including pink ones at he edge and the orange ones at the soil pit. That drawing should be submitted to the LGU with your permit applications. You are required to avoid wetland impacts if possible. If your plans include grading in the wetland basins, a Wetland Alteration Permit Application and a mitigation plan will be required.
