Introduction In accordance with your request, LGC Geotechnical, Inc. (LGC Geotechnical) has prepared this letter to provide geotechnical release from rough grading of Lot 1, “Petra” Units 35 and 36 for Tract No. 18148, Proposed Residential Development located at the southwest corner of Calle Arroyo and Paseo Tirador, in the City of San Juan Capistrano, California. Project No. 20266‐01 Page 2 March 29, 2022 Geotechnical Release from Rough Grading LGC Geotechnical recently provided geotechnical observation and testing services during grading for the subject area. Observation included over-excavation and removals of unsuitable materials, placement of compacted engineered fills and finish grade testing. Where tested, compacted fill materials placed were found to meet the project specification of at least 90 percent relative compaction, as determined by ASTM Test Method D1557. A comprehensive as‐graded report documenting our observations and testing during rough grading for the entire site will be presented in a forthcoming report. Based on our observations and testing during grading, we consider the subject lots to be generally suitable for their proposed use from a geotechnical standpoint provided the recommendations included in the referenced reports (LGC Geotechnical, 2021a, 2021b & 2021c) and future applicable geotechnical reports are appropriately implemented. The subject area was constructed in general accordance with our recommendations and the requirements of the City of San Juan Capistrano. Should you have any questions regarding the content of this letter, or should you need any additional information, please do not hesitate to contact our office. We appreciate this opportunity to be of service. Sincerely, LGC Geotechnical, Inc.
