Based on the conditions encountered during our fieldwork, the site is • primarily underlain by native soils consisting of medium dense to very dense silty sand with • gravel glacial till deposits. • We understand construction of a multi-family apartment complex is proposed for the subject • property. One level of below grade construction relative to existing grades surrounding the • property is proposed. Temporary shoring or open-cut excavations along the north, south, and west perimeters of the site will be necessary to construct the underground garage level. To the • east, the building structure will daylight along the Broadway Avenue North frontage. Based on • current plans, excavations on the order of 12 to 15 feet will be required to establish subgrade • elevations for the below grade level. This geotechnical study provides foundation design • recommendations and recommendations for conventional shoring and soil nailing. • Based on the results of our study, construction of the proposed development is feasible from a • geotechnical standpoint. The building can be supported on conventional foundation systems • bearing on competent, undisturbed native soil. Based on the proposed excavation depths and the subsurface data acquired at the boring and test pit locations, we anticipate competent • native soils suitable for support of foundations will be encountered at the proposed foundation • level. Recommendations for site excavations, foundation design, temporary shoring, and other pertinent geotechnical recommendations are provided in this study, as appropriate. • The opportunity to be of service to you is appreciated. If you have any questions regarding the • content of this geotechnical engineering study, please call. • iv„ • cer , •.
