Dear.Ted, . . � . .. � . . . , . ' . � . � .. � . <br /> � I-returned to� the Mt.� .View site��at lOth� Place South,� - '� �� � � . . <br /> � � immediately south� of �%avier Way-�in Everett.. �The� purpose of � � <br /> � my sit= visit was to gather addit;.onal information on"the <br /> soils of the £lat grassland portion of the� property. , . <br /> � � In addition to my investigation, I also viewed boT:i the soil ... � <br /> test oits in the field and the- oeotechnicaY report� prapared <br /> by Couvrette Geotechnical Engineering. Based ,upon ny <br /> � observations from our� initial site investigation last <br /> � summer, my recent site visit, and the Couvrette study, I <br /> , firmly�believe that no wetland areas exist within this <br /> grassland, or anywhere else on the site,� other than those <br /> - areas designated as wetland� on the oriqinal wetlands <br /> � technical report. . <br /> � 2 viewed the Couvrette tes� pits, mostly located in the � <br /> - � western�and south-central portions of the site, and , <br /> � - � subsequently dug seve:al more in the northern �and eastern <br /> � . � � portions oP the grassland.. Following is a .summary of my , <br /> � - ' - findings. . � .. . , . . � <br /> - � . . Despite.recent -record-setting -flooding �in .this region, �few�. � ' <br /> �� � of the test pits showed saturated soil• conditions within 2 <br /> feet of the surface. In fact, the-Cou�•_ette report . <br /> � indicated that the shallowest water �eepage was at depths of <br /> greater than 2 feet. While Che soil was� saturated at depth.; <br /> ranging from 4 inches to 1.75 feet in the pits that Z dug, <br /> these investigations were made during tiie wettest portions <br /> of the year. It is highly unlikely that saturated <br /> conditions would be Triund �+ittin� l foot of the surface for a <br /> caeek or more auring cne growing �esscn. Tnrieed, bocn oi ny � <br /> investigations included pits du�; in the.middle of several �• <br /> small patches of plants that are often associated with � <br /> wetl:,nds (black cottonwood saplings, soft rush, hardhack <br /> . � spirea) . Even in these arezs, th-, soils were brown (Munsell <br /> colors lOYR 4/� -�/3) and had virtually no organic mattei <br /> accumulation, even at the soil surface; none .of the <br /> �� mandatory criteria �ere met for hydric soils (accordinq to <br /> the Federal Manual for the- Determination and Delineation of <br /> Ju:isdictional {Jetlands) in these areas. .
