2701 ROCKEFELLER AVE NIMBUS Geotech Report 2023-12-29

GEOTECHNICAL ENGINEERING STUDY Proposed Multi -Story Building 2701 —2711 Rockefeller Avenue Everett, Washington This report presents the findings and recommendations of our geotechnlcal engineering study for the site of the proposed multi -story building to be located In on the southeast corner of Everett Avenue and Rockefeller Avenue in Everett. Development of the property is in the planning stage, and detailed plans were not available to us at the time of this study. However, we were provided with conceptual plans which were developed by Clark Barnes Architects and dated October 9, 2018 that indicates the existing parking lot and small existing building will be demolished, and a new multi -story building will be constructed on the site. It appears that the proposed building will have little to no setbacks from the property lines. We understand the new building will have six stories above the upslope, western side of the site overlying three stories of below -grade parking. The ground surface drops approximately 10 feet in elevation from west to east across the site, therefore It is likely there will be only two levels of below -grade parking at the adjacent alley to the east. Excavation depths in the order of 20 feet below the eastern adjacent alley and 30 feet below the western adjacent Rockefeller Avenue are anticipated. If the scope of the project changes from what we have described above, we should be provided With revised plans in order to determine if modifications to the recommendations and conclusions of this report are warranted. SITE CONDITIONS SURFACE The Vicinity Map, Plate 1, Illustrates the general location of the site on the southeast comer of Everett Avenue and Rockefeller Avenue in Everett. The rectangular -shaped subject site is comprised of five adjoining parcels with address of 2701 to 2711 Rockefeller Avenue from north to south. The subject she as a whole has dimensions of 200 feet in the north -south direction and 120 feet in the east -west direction. An asphalt parking lot covers the almost the entire subject property; however, a small two-story commercial building Is located near the center of the site. The ground surface slopes gently downwards from northwest to southeast across the properly. The eastern perimeter of the site is generally 8 to 10 feet below the ground surface along the western property line. A small 2- to 3-toot-tall modular -block wall borders the western edge of the southern hat of the parking lot where the parking surface is below Rockefeller Avenue to the west. As discussed above, the site Is bordered by Rockefeller Avenue, Everett Avenue, and an alley to the west, north, and east respectively. A one-story commercial building (2719 Rockefeller Avenue) borders the site to the south; the adjacent building overlies a full basement floor beneath Rockefeller Avenue which daylights to the alley to the eastern alley. The building appears to be of brick constructlon over concrete foundations with footings near the ground surface of the subject site's parking lot elevation. GLOMCH CONSULT*re, INC.
