(USGS) Topographic maps. Areas indicating evidence of potential wetland conditions were <br /> evaluated in greater detail through fieldwork. <br /> Precipitation Data Analysis <br /> Precipitation data from the Minnesota Climatology Working Group and Natural Resources <br /> Conservation Service WETS Tables were used in conjunction with the NRCS Method for Evaluating <br /> Antecedent Moisture Conditions to determine precipitation conditions under which the investigation <br /> was conducted. <br /> Field Sampling Procedures <br /> Sample transects were established in representative transition zones between wetland and upland <br /> for each observed plant community. For potential wetland areas greater than five acres in size, a <br /> minimum of three transects were established along the baseline wetland boundary for lengths of up <br /> to one mile, three to five transects for one to two miles, five to eight transects for two to four miles, <br /> and eight or more transects for wetland baseline boundaries that exceed four miles in length. <br /> Transect intervals do not exceed 0.5 mile apart for each other. <br /> Transects are comprised of two sample points, one sample in upland and one sample point in <br /> wetland. A field data sheet was completed describing the dominant soil characteristics (to a <br /> minimum of 24 inches below the soil surface), plant communities, and hydrology indicators at the <br /> sample point. The presence of water was observed after time (depending on soil characteristics) <br /> was allowed for movement of water through the soil substrate. Absolute percent areal cover was <br /> recorded for the species that were observed (which may exceed 100% total area due to overlap) <br /> and dominance was determined by using the 50/20 rule. Vegetation was sampled within each <br /> stratum present at a sample point using the following circular plot sizes: <br /> • Trees - 30 ft radius <br /> • Saplings and Shrubs - 15 ft radius <br /> • Herbaceous - 5 ft radius <br /> • Woody Vines - 30 ft radius <br /> The sample points were marked with 4-foot lathe, photographed, and flagged with surveyor's tape <br /> (if not within an agricultural land use). Other samples were taken at unmarked locations to provide <br /> verification of the wetland edge, as needed. <br /> Wetland Boundary Delineation <br /> � <br /> 1205 & 1225 Shoreline Drive Page 4 <br />
