7800 EVERGREEN WAY HYUNDAI Wetland Report 2025-08-05

1.0 INTRODUCTION This geotechnical engineering report presents the results of GeoEngineers' geotechnical engineering services for the proposed improvements to the existing Lee Johnson Hyundai Dealership located at 7800 Evergreen Way in Everett, Washington. The site is located northeast of the intersection of 79th Place SE and Evergreen Way and is shown relative to surrounding physical features on Figures 1 and 2. We understand that LMJ Enterprises is planning to expand the east side of the existing Hyundai car dealership to construct a new showroom, service area drive -through, and to make improvements to the parking and sales lots. Associated improvements include sidewalks, underground utilities, and landscaping. The purpose of this report is to provide geotechnical engineering conclusions and recommendations for the design of the planned addition to the existing Lee Johnson Hyundai Dealership. GeoEngineers' geotechnical engineering services have been completed in general accordance with our agreement dated June 24, 2021. 2.0 FIELD EXPLORATIONS AND LABORATORY TESTING 2.1. Feld Explorations Subsurface conditions at the site were evaluated by drilling three borings (B-1 through B-3) to depths rangingfrom approximately 12 to 21 feet below existingsite grades (bgs). The approximate locations of the borings are shown in Figure 2. A description of the field exploration program and summary boring logs are presented in Appendix A. 2.2. Laboratory Testing Soil samples were obtained during drilling and were taken to GeoEngineers' laboratory for further evaluation. Selected samples were tested for the determination of moisture content and grain -size distribution. A description of the laboratory testing and the test results are presented in Appendix B. 3.0 SITE CONDITIONS 3.1. Surface Conditions The site is currently occupied by two single -story commercial buildings consisting of the Lee Johnson Hyundai of Everett building and the associated service center. The site is bounded by commercial property to the south, Evergreen Middle School to the west, a church to the north, and Evergreen Way to east. The site gently slopes down from approximate Elevation 552 feet near the southwest corner to about Elevation 532 feet near the northeast corner of the site. The buildings are surrounded by asphalt pavement, hardscape and landscaping. Underground utilities at the site include, but are not limited to, sanitary sewer, storm drain, gas, water, power, and telecommunications. GEOENGINEER� December6, 2021 Pagel File No. 24 59-003-00
