Fill and cut slopes arc_located on both <br /> sides of thc flat area. 'iliese slopes have a moderate to stcep inclination and exist in thc north, south and <br /> K'CSI 3fC85. <br /> lhe sitc wifl consist oi 44 units oE multi-family housing and parking garages. 71ie dcvclopment ��•ill be <br /> accased from Glcmvood Avenue which borders ffie c.ut side of t1�e site. One private access road, in U�e <br /> east to west direction, is currenUy planned lo service all of the uni(s. The previous gcotcchnical sludies <br /> identificd fill and I:uidslidc areas on the site. 71ie planncd development appcars to bc Iceatcd outside of lhc <br /> kno�m landslide areas in d�e western portion of the sitc. About half of tlie units .vill be located on the <br /> northem portion of llic sitc that is underlain by fill idcntificd in ocr past explorations. Most oC thc planncd <br /> development���II requirc minini�tl cl�uigcs in site elevations. A small east trcnding ridge will be rcmoved in <br /> U�e soulh central portion of the site. A 2N:IV slope is planned to blend diis cut back into the existing <br /> upslopc topography. <br /> A detcntion pond is planned in the nortlieast comcr of thc sitc. The pond will have a ma+cimum ���ater <br /> storage elevation oF329.0 feet. 77u pond�vill consist of two main cclls onc oPwhich is for open watcr and <br /> Uie oll�cr for �vet pond u��almcnt Thc bottom elevations of the open water and wet pond trcaUnent cells <br /> tvill bc at 31R.7 and 321.7 feet, respectively. "Il�e sidc slopes of thc berm will have a 3 Harizontal:l <br /> Vertical (f I:V) on tl�c itrterior and 2H:1 V on die cxterior. <br /> SCOPE <br /> "[lie purpose of this study is to explo�e and characterize U�e subsurface conditions, and present <br /> rccommendations for site devclopment oPUie founJn(ion,delention pond,roadway and utility trenches. 71ie <br /> cxploration program was designecl to supplemcnt die original dala and to cvaluate at specific areas �vhcre <br /> thc sitc improvcmcnts arc planncd, Spccifically, our scope ofservices include the following; <br /> I.
