The USGS quad map <br /> ' shows that surface drainage generally flows to the northwest, eventually to Lake Claussen then to <br /> Lake Minnetonka, Minnehaha Creek and then on to the Mississippi River. Soil samples were taken <br /> to observe the soil texture and hydrology. Wetland hydrology indicators were not observed in areas <br /> ' other than in the wetland area delineated. <br /> ' Rainfall in April, 2006 had been 3.66 in. above normal as measured at the National Weather Service <br /> Office in Chanhassen. <br /> ' Soils <br /> The Hennepin County Soil Survey as shown in Figure 7 identifies the following soils in the vicinity: <br /> ' Symbol Name Hydric Yes/No <br /> Co Cordova Yes <br /> ' Ha Hamel Yes <br /> Lrb Lester Yes <br /> Ltb Lesuer Yes <br /> Vegetation Communities <br /> ' Vegetation communities observed on the site included Kentucky bluegrass sod, old field, and <br /> emergent wetland. One partially drained Type 2/3 wetland community and an additional Type 2 <br /> wetland community were observed on the site.Dominant species in the wetlands included reed canary <br /> ' grass, several sedge species, horsetail, willows and cattails becoming more prevalent in wetter <br /> portions of the basin. In upland areas, Kentucky bluegrass sod, dandelion and goldenrod were the <br /> dominant plants. <br /> Findings <br /> Two wetlands were delineated on the site. Wetland W-1 extended beyond the property boundaries. <br /> Pin flags and ribbon were numbered and placed along the delineated wetland edges for the surveyor <br /> to locate. The same was done for wetland W-2. <br /> ' This report presents the data obtained from off-site sources and the field investigation on the site. <br /> Other areas on the site that were depressions or swales were also assessed for wetland conditions. <br /> ' A two point transect was sampled perpendicular to the wetland boundary utilizing Corps ofEngineers <br /> (COE)routine method. No other areas met the COE wetland criteria. The narrative below describes <br /> each wetland. Wetland size listed in this report is approximate. <br /> 8040 5tevens Avenue South - Bloomington, Minnesota 55420-1236 F <br /> Voice (952) 888-4901 - Fax (952) 888-4901 <br /> acorn@iaxs.net- www.acomenvironmental.com <br />
