SCOPE OF WORK Our scope of work consists of field and laboratory programs to evaluate the physical and engineering properties of the onsite soils. Description of the exploration and laboratory programs are presented below. EXPLORATION AND FIELD INVESTIGATION PROGRAMS On May 1, 2024, a field exploration was performed, which consisted of 2 borings, in the approximate location of the proposed ADU. Prior to the exploration it had been raining the week before and soil was very moist, and eventually reached ground water. Hole #1 was drilled to a depth of 10 ft. Equipment used was a hand operated power auger with extensions. Moisture tests taken at 12" was 19.5%, at 24" was 41.8% and at 82" was 19.8%. Ring samples taken at 5ft and bulk sample taken at 10 ft. for laboratory testing. The soil encountered was brown silty clay. The description of the subsurface soil and the depth of boring #1 are shown in Boring Log Cl. Hole #2 was drilled to a depth of 5 ft. Equipment used was a hand operated power auger with extensions. Moisture tests taken at 12" was 24.7%, at 24" was 43.2% and at 60" was 15.1 %. Ring samples taken at 3 ft and bulk sample taken at 5 ft. for laboratory testing. The soil encountered was brown silty clay.
