Fol!owing expiorations, we v��ere provided e•rilh an updated <br />alan of the development; lhis was prepared by ARC Architects. Tne plan indiczted that a buildinr, <br />i; proposed on lhe soulhwestem corner of ihe dev�lopment slle and on the eastem s�de of lhe sile. <br />The �vestern porlion of the soulh�vestern building will have a finish (loor grade oF elevation 98 teet, <br />:vhile the eastern portion will be at elevation 94 feet. The eastem building will also have finish floor <br />grade of elevation 94 feet. These tinish Ooor grades �vill generally be near or just above the <br />existing ground level. <br />If lhe scope of the project changes from what we have described above. �ve should be provided <br />�.vith revised plans in order to determine if modificatio�s to lhe rocommer.dalions and corclusions o! <br />this report are warranted. <br />SITE CONDITIONS <br />SURFACE <br />The Vicinity Niap, Plcte 1, illustrates the general location of the site in the northem portion of <br />Everett. The site that will be developed is on the southem side of an existing Army Reserve <br />Facility, located at the corner o( Rainier Avenue and 11th Street. 7his development area is <br />currently mostly covered with hvo parking lots. Both !ots slope slighUy do�vnward to ihe wesL The <br />eastem lot is siluated about 4 feet beloev the �.vestern lot. A sleep slope separates lhe two parking <br />lots. <br />The properly lo the evesl of the site is approximatety 10 feet above the weslam parking lol; a sleep <br />slope separates the site from ihe adjacent �vestern property. The area east of 1he sile siopes <br />gentiy av�ay irom it. <br />SUBSURFACE <br />The subsurface conditlons were explored by drilling six test bonrgs at Ihe approximale locafions <br />shotivn on the Site Exploration Plan, Piate 2. Our exploralion program �vas based on iha proposed <br />construction, anlicipated subsurface conditions and those encountered during exploration, and the <br />scope �f �vork outlined in our proposal. <br />The tesl borings were drilled on May 3, 2012 using a lraiter•mounted, hollor:-stem auger dnll. <br />Samples were taken at 2.5 to 5-foot intervals wilh a sl2ndard penetration samplec This split-spoon <br />sampler, evhich has a 2-inch oulside diameter, is dri�ien into the soil wilh a 140-pound hamrner <br />falling 30 inches. The number of blo�vs required lo �dvance ihe sampler a given dislance is an <br />indication o( the soil deosity or consrtency.
