74', �k' i . �3:': ! GEOTECHNICAL ENGINEERING STUDY � 19TH STREET STATION i. . � 19iH AVENUE SOUTREAST � EVERETT� WRSHINGTON ; This repoct pcesents the xesults of our geotechnical , engineering study , of the site of the proposed 19th Street j Station cetail building to be constructed in the Silver Lake Iarea of Everett in Snohomish County. The site is located on I 19th Avenue Southeast or the Bothell-Everett Highway (SR 527) as indicated on the Vicinity Map, Plate 1. Based on a preliminary site plan furnished to us, we anticipate that the development will consist of a one-story, slab-on-grade structure having. dimensions of 65 feet by 180 feet . No site grading plans were developed, but basQd on out convezsat.ions with yotY, we anticipate that sane fill will be placed in the building area and the existing filled area will be lowered . SITE CONDITIONS SURFACE The site is on the west side of the Bothell-Everett Highway, south of a veterinazy clinic and a dental clinic, north of Silver Lake. The essentially rectangular site has been filled to be relatively level with the stteet on the east side. This filled area is covered with grass and is on the order of 196-136 feet in depth. The remaining portion of the site is � covered with a dense gzowth of fouz to eight inch diametet alder trees . This area slopes gen:ly to the west. A sewer line has recently been constructed along the sooth edge of the property. SUBSURFACE The subsurface conditions were explored by excavating four test pits at the approximate locations sho�dn on Plate 2. The test pits were excavated on May 7, 1967 with a rubber-tired backhoe owned and operated by Evans Brothers Excavating. A principal geotechnical engineer from our staff observed the excavation process , logged the test pits , and obtained representative samples of the soils encountered . The Test Pit Logs are attached to this report as Plates 3 and 4. GE07'I:CII CONSULTAN'CS INC. �
