Soil pits were made earlier that day for percolation tests. Several of Lhe test holes were open ana could be observed for soil color and texture. Soil colors were determined by matching them to a Munsell Soil Color Chart. The soils were examined for hydric characterisrlcs suc.i as: low chroma, organics, mottling, gleying, and moisture. Soil samples were observed at points mside the basins with some wetland characteristics, at the basin/wetland edge, ar.d mto the zones. The soil pits w; re marked with orange stake flags labeled “A" vnthin the weLand, ^ at the wetland edge, and “C” at the upland pit. Conditions at the soil pits near the deuneatew wetland edges are described on attached Data Forms. The wetland edge is usually determined to be near the poLnt where evidence of subsurface water is within 12" of the ground elevation, where at least 50% of the vegetation is hydrophytic, Mw where hydric soil is encountered. In the areas delineated as wetlands at this site, the identifiable vegetation was more than 50% hydrophytic and hydric soils plus evidence of wetian- hyuroiogy were found. Wetland 1 is mostly a Type 6 wetland with reed canary grass (Type 2) areas at die Sringe. The w-oland is designated on the NWI map as PFOlCd/PEMCd.

Data Forms - Routine Onsite Determination Method were completed for conditions at the wetland and arc attached to this report. Other small patches of reed canary grass with aspen or willows were noted.

The Minnesota tules require that designers attempt to avoid wetlano impacts^ It yom ptos include HI or grading in the wetland basins, you will need a Wetland Alteranon Permit from Minnehaha Creek Watershed Distria (MCWD). The delineated wetland edge must be snowr. on your grading plan. Please contact me a: 612-974-9856 with any questions regaromg wetland issues for this site. 9S0t2*tt_Crtnbtrj Orono
