The outline of the wetland/upland transition <br />wai staked by myself with input from Dave Squire, McCombs Frank Ross <br />Associates, and Jeanne Mabusth, City of Orono. and subsequently surveyed by a <br />crev from McCombs, Frank Roos Associates. A map of the wetland delineation is <br />enclosed. The wetland soils are classified as a peaty muck (based on the <br />Hennepin County Soil Survey (Pa - peaty muck)), and support vegetation that is <br />dominated by reed canary grass (Phalaris arundinscea). Reed canary grass <br />seemed to delineate the wetland area and ooldenrod a.nd other ester species <br />characterized upland areas. The transition from voclami to upland sre&a was <br />oiarked with a change in organic content o£ the soils. Wetland soils uere <br />peaty (highly organic) and upland soils had more mineral content, with some <br />sand found in the subsoil. <br />In the wetland area, the water table was approximately 1<* inches below the <br />surface while in the upland area, it was greater than 18 inches. The map of <br />the topography of the wetland shows a gradient with a high point of 944.95 <br />near the Orono Orchard Road, sloping to 940.15 near the Long Lake stream. <br />A potential building site to the south of the stabilization pond was also <br />reviewed. This site, which formerly was a wetland area, was filled with <br />borrow material around the time of the pond construction in the 1960's. There <br />are no strong Indicators now present that would characterize this area as a <br />wetland area (based on hydrology and vegetation). The fill material at the <br />site is a grey-brown sandy clay loam that is heavily mottled. This fill <br />material probably was mottled when it was placed in this area. <br />210 <br />2335 West Highway 36 • St. Paul, Minnesota 55113 • 612*636-4600 • 35th Anniversary
