524 S Shawnee Dr. <br />Santa Ana CA 92704 <br />INTRODUCTION <br />Priority Engineering has conducted a site inspection, made a physical test of on-site soils and prepared <br />the following report of Geotechnical Investigation for the residential property located at 524 S <br />Shawnee Dr. Santa Ana CA 92704. The investigation was made to provide site evaluation and design <br />data for the foundation of the proposed new accessory dwelling unit (ADU) to be constructed on the <br />site. <br />SITE DESCRIPTION <br />The site, Assessor Parcel 109-833-17. <br />Latitude 33.7397766 <br />Longitude -117.9105262 <br />The site is a 6098 Sq ft rectangular shaped lot. The north property line is 100.19 ft long and south <br />property lines is 85 ft long. The east property line is 58 ft long and west property lines is 61 ft long. <br />The existing residence is a 3 bedroom, 2 bathroom single family home, 1310 sq ft structure, built in <br />1961 with an attached garage. <br />Surrounding houses are composed of single family, wood framed, residential structures on similar size <br />lots. Rear yard has a perimeter block wall. <br />SCOPE OF WORK <br />Our scope of work consists of field and laboratory programs to evaluate the physical and engineering <br />properties of the onsite soils. <br />Description of the exploration and laboratory programs are presented below. <br />EXPLORATION AND FIELD INVESTIGATION PROGRAMS <br />On April 17, 2024, a field exploration was performed, which consisted of 2 borings, in the <br />approximate location of the proposed ADU. <br />Hole #1 was drilled to a depth of 10 ft. Equipment used was a hand operated power auger with <br />extensions. Moisture tests taken at 28" was 15.8%, at 64" was 24.4% and at 102" was 28.6%. <br />Ring samples taken at 5ft and bulk sample taken at 10 ft. for laboratory testing. <br />The soil encountered was brown sandy silt. <br />The description of the subsurface soil and the depth of boring #1 are shown in Boring Log Cl. <br />Hole #2 was drilled to a depth of 5 ft. Equipment used was a hand operated power auger with <br />extensions. Moisture tests taken at 12" was 15.3%, at 36" was 11.3% and at 60% was 25.7%. <br />Ring samples taken at 3 ft and bulk sample taken at 5 ft. for laboratory testing. <br />The soil encountered was brown sandy silt. <br />The description of the subsurface soil and the depth of boring #2 are shown in Boring Log C2. <br />1 <br />524 S Shawnee Dr & <br />Unit# 22/7/2025
