Geo�echnical Engineering. Basen ,upon my <br /> observatio�. from our initial andethevCouvrettenstudy, I <br /> summer, my re:cent site visit, <br /> firmly believe that no wetland areas exist within this <br /> grassland, or anywhere else on the siteinalhWetlandsthose <br /> areas designated as wetland on the orig <br /> technical report. <br /> j�"'� I viewed the Couvrette tesp pits, mostly locatedand the <br /> 'r r western-and sou'th-central ortions of the site, <br /> subsequently dug several more in the northern and eastern <br /> iportions of the grassland., Following is a :-ummary of my <br /> ���.' f indings. <br /> �"+ in this region, few <br /> - Despite recent record-setting flooding <br /> of the test pits showed saturated soil conditions within ' <br /> Peet of the surface. In fact, the Couvrette report <br /> I ..�� indicated that the: shallowest water s�epage was at depths of <br /> gr.eater than 2 feet. While the soil was saturated at depths <br /> ranging from 4 inches to 1.75 feet in the oits that I dug, <br /> <..o these iiivestigations were made during the wettest portions <br /> a` 0 ef the year. It is highly unlikely that saturated <br /> conditions would be fc�und within l foot of the subocneoTomya <br /> ti�eek or more aur.ing L'ne growino :,esscn. Zncieed, <br /> investigations included pits dug in the middle of several <br /> ��,�� small patches of plants that are oftes ftsrushtehardhack <br /> wetlands (black cottonwood saplings, <br /> � spirea) . Even in these areas, the soils were brown (M',l��sell <br /> ,�, colors lOYR A/3 -3/3) and had virtually no organic matter <br /> �`�,� accumulation, even at the soil surface; none of the — <br /> mandatory criteria k�ere met for hydric soils (according to <br /> the Fe dera l M a n u a l for the De2ermination and Delineation of <br /> Jurisdictional Wetlands) in these areas.
