<br />2 <br /> <br />The Soil Survey (USDA NRCS 2015) showed Isanti (Predominantly Hydric) as the mapped <br />hydric soil type on the property. Soil types mapped on or near the property are listed in Table 1 <br />and a map showing soil types is included in Figure 4. <br /> <br />Table 1.

At that time, trees and shrubs still had leaves and some herbaceous vegetation was <br />actively growing while others were beginning to senesce. Climatic conditions were below <br />typical (dry) based on the Gridded Database Method (Attachment B). <br /> <br />Other than mowed lawn areas, the majority of the site was woodland. Species observed <br />included: bur oak, common buckthorn, green ash, boxelder, sugar maple, black walnut, catalpa, <br />black cherry, quaking aspen, honeysuckle, red-berried elder, river-bank grape, Virginia creeper, <br />hog peanut, big-leaf aster, motherwort, garlic mustard, black nightshade, catnip, white snakeroot, <br />three-seed mercury, lilac, cinquefoil, raspberry, common plantain, stickseed, violet, clearweed, <br />and common burdock. <br /> <br />One depressional area was observed in the northeast portion of the site. A sample point taken <br />within the depression (SPA; Figure 2 and Attachment C). SPA was dominated by a canopy <br />of sugar maple with a sparse understory of common buckthorn. Soils were light brown loamy <br />sand to 24 inches. No primary or secondary indicators of wetland hydrology were observed, <br />including geomorphic position which did not apply due to the presence of a functioning drainage <br />system and high permeability soils. This depressional area was determined to be non-wetland <br />based on the lack of a dominant hydrophytic plant community, lack of hydric soil, and lack of <br />wetland hydrology. <br /> <br />An intermittent drainageway that flowed into the site from the south and flowed out of the site <br />towards the east was observed. A curb cut at Sherwood Road allowed untreated roadway runoff <br />to enter the drainageway. The bottom of the drainageway was unvegetated and was not saturated
