. GEOTECHNICAL ENGINEERING STUDY Proposed Rucker Village Condominiums Grand Avenue at 38th Street Everett, Washington Ti�is report presents the findings anJ rer.ommendations of our yeotechnical engineering study for t;ie site of the proposed Rucker Village Condominiums in Everett. The Vici��ity Map, Plate 1, illustrates the general location of the site. We were provided witn a Preliminary Grading plan of Rucker Village. The plan, which was developed by Ostergaard-Robinson and Associates, is dated Octobe� 1, 1996. The plan shows t��e property dimensions, existing topography, proposed building foetprints, proposed finish floor elevations, and general final grading. Based on the provided plan, and on discussions with James Pirie, we anticipate that three multistory condominium buildings �vill be constructed on the property. Each of these buildings will be underlain by a par'<ing garage. The garage floor elevations will be 310 feet for Buildings 1 and 2, and 305 feet for 13uiiding 3. Paved parking will also be provided outside of the building footprints. Vehicle access tc the site �.aill be from High Street, which defines the southwestern border of the site, and from the alley along the eastern side of the site. Access is • also provided at the northeasterr corner from 37ih Street and at ;he southeastern corner from 38th Street. ' Extensive grading �vill be required for this development. Cuts of up to at least 10 feet will be needed for the upslope side r,r each building, while fills of 10 to 15 feet are planned under the opposite, downslope, sides of the buildings. Generally, the cer.tral portion of the property will be cut down, and filis will be placed along the western and northern s;des for building, parking, and drivevday areas. ?he northern driv�way and northwestern parking areas will require fills of up to 20 feet above the existing ground surface. Retaining walls rising up to 1� feet in height above the sloping fill appear necessary at several corners of the parking areas. SITc CONDITIONS Surface The irregularly shaped parcel was unc'eveloped at the time of our field work. We did, however, note a cor�crete slab in the centrai portion of the si?e that may be the remains of a structure. Concrete rubble was piled arourd this slab. Vegetation on the site consisted primarily of grass and weeds. A heavy growth of blackberry vines extends along the southern, western, and northern boundaries of the property, and numerous small, deciduous trees were scattered around the site. The 37th and 38th Streets abut the nortF�ern and southern property lines. Grand Avar�ue curves along the northwestern side of the property, while High Street extends along the southwestern side. A gravel alley adjoins the northern half of the eastern boundary. � The ground surface generally slopes down in all directions away from the center of the site. Along the southern and eastern edges of the property, the ground slopes moderately at an inclination cF no more than 20 to 25 percent. The western and northern approximate 120 feet of the site slope steeply at an average inclination of 40 percent. A majority of these steep slopes appear to have . been created when High Street, Grand Avenue, and 37th Street were constructed. There are � GEOTECfI CONSUCfANTS,INC �/Z� L
