Based on the subsurface conditions encountered at the boring locations, the site is underlain by younger alluvium (Qyal) deposits consisting primarily of silt and sands that are dense to very dense and in a moist to wet condition. Groundwater seepage was reported at depths of 3 to 14 feet below existing grades, and should be expected during construction activities depending on the time of year they take place. Based on the results of our study, the foundations for the proposed residential buildings should be supported on at least two feet of structural fill following the successful completion of a surcharge or preload program. Consolidation settlement is to be expected with site improvements, including foundations, retaining walls, utility trenches, and other necessary elements. The recommended use of a preload or surcharge program and appropriate settlement mitigation measures are primarily due to the highly..compressible nature of the on- site fill and younger alluvium deposits. This report provides recommendations for settlement mitigation, grading, foundation preparation, drainage; pavement sections, and other project-specific geotechnical recommendations. We appreciate the,opportunity to be of service to you on this project: If you have questions regarding the content of this geotechnical evaluation, please call.
