(Pinnacle) was recently retained by Ms. Madalcn Pidgeon to <br />assess the wetland/drainage issues on her five-acre parcel of land located at 66.5 Orchard <br />Park Road (Site) in Orono, Hennepin County, Minnesota. Ms. Pidgeon reported and had <br />pictures documenting that her property has become increasingly inundated since she <br />purchased it in 1985. Our .scope of work included visiting the Site to document the <br />current conditions, reviewing current and historic aerial photographs at the City of Orono, <br />and compiling our findings in this letter report. <br />Site Ob.scrvation <br />Pinnacle visited the Site on July 10, 2003 to document the current Site conditions. The <br />.Site visit revealed that there is cuiTer.tly a Circular 39, fype 4, deep marsh wetland at the <br />Site that extends to the north and south, beyond the Site boundaries. The northern <br />portion of the wetland is circular-shaped and is inundated with approximately 5-10 feet of <br />open water. Numerous dead trees were observed in this portion of the basin, indicating a <br />significant rise in the water levels that sub.sequcnlly drowned these trees out. As the <br />wetland proceeds south, it narrows down to a linear area of open water that stops at the <br />Pidgeon’s south property line, where there is a distinct vegetative and hydrologic change. <br />The wetland type changes from an open water. Type 4 deep marsh basin to a Type 2, wet <br />meadow wetland that is vegetated with reed canary grass and has minimal standing water. <br />No natural topographic changes were observed at the property line that would cause this <br />obvious change in wetland types. It appears that .sometlnng at the south property line is <br />blocking the natural outlet, impeding the water fiom following its natural course to the <br />south into a .separate wetland basin. <br />f <br />Minnoitpohs.
