Subsurface Erploration, Gcofogic Haard, and <br />Befvrdc�e Lots East Preliminary Geoi '�vical Engineering Repon <br />E��rretr Washim m� �rct and Sire Condi�ions <br />2.0 PROJECT AND S1TE DESCRIPTION <br />The subject site is Incated on the east side of Belvedere Avenue south of Harber Lane in <br />Gverett, Washington �Figure 1). The site consists of three undeveloped lots (Lots 32 through <br />34) located on the east ilan}; of a north-south trending ridge. The topography of the portions <br />uf the lots adjacent to Belvedere A��enue is gendy to <br />Approximately 50 to 150 fect east-northeast of Belvedere Avenue, the <br />opography slopes steeply down��afcfio�'ard the no�fheast into a dra ge ravine�� <br />that radients on the slo e ran e iro <br />he��. . e upper, genUy to mo erate y s opmg portion of the <br />site is vege[ated primarily by field grasses and light brush wi[h some trees in the northern <br />portion of the site (Lots 33 and 34). Vegetation on the steep slope in the eastern portion of the <br />site consists of thick natural brush N�ith scattered deciduous trees. <br />This rePort a�as completed with an understanding of thc project based on review of the <br />topographic site plan prepared hy ASPI (undated), and on discussions with Mr. Marry Robine�t <br />of Belvedere, LLC. lt is our understanding that present plans call for the construction of <br />single-family homes on each of the three building lots. Construction details including the <br />locations of the proposed buildings �vithin the lot boundaries had not been determined at the <br />time of our stud��. <br />3.0 SUBSURI�ACE L•XPLOk.A'I'IOtv' <br />Our field smdy included exca��ating a scries of e�:ploration pits and drilling tµ•o expforation <br />horines to gain suhsurfacc information about thc site. The ��arious t}�pes of sediments, as well <br />as the depths «here characteristics o( the sediments changed, are inuicated on the exploration <br />loes presented in the Appendix. The depths indicated on the logs where conditions changed <br />may represent gradational variations betu�een sediment types in the field. If changes occurred <br />hetti�een sample inter��als in our borings, they were interpreted. Our explorations were <br />approximatel}� located in the fieid by measuring from kno��•n site fea[ures sh�wn on the <br />previously referenced topographic site plan. <br />'I'he condusions and recommendations presented in this report are based, in part, on the <br />explorations completed for Aiis smd}�. The number, location, and depth o( the explorations <br />were completed �vithin site and budgetary constraints. Because of the namre of exploratory <br />��-ork bclo�� ground, cxtrapola[ion of subsurface conditions between field explorations is <br />necessary�. It should be noted that differing subsurface conditions ma�� sometimes be present <br />due to the random nature of deposition and the alteration of topography by past grading and/or <br />filling. The nature and eaten� of any variations between the field explorations may not becorne <br />fiill� e��idcnt uniil construction. If variations are observed at that time, i� may be necessary to <br />re-e�alua�e specific recommendations in this report and make appropriate changes. <br />hlnrdt 5, 200J ASSOCIATED EARTN SGENCES. /,NC. <br />r:�•,�- �:r���,�„h. �,��.�;.:�.,»�,.�.E,�:�� w.� Page 2 <br />
