330 Land Company, LLC 9785.004.001 Arroyo Lago October 31, 2025 RESPONSE TO CITY REVIEW COMMENTS Page 7 BSK Comment – Off-Site Feasibility Report The primary geotechnical concerns identified by the off-site feasibility report that could affect development of the site are the existing undocumented fill, expansive soil, seismic hazards, slope stability and compressible soil. In order to address these concerns, the report recommended that a surcharge program or ground improvement be performed at the off-site project sites. Based on our review, we believe the off-site feasibility report provides appropriate preliminary earthwork mitigation and recommendations. As discussed in the off-site feasibility report, a design level report should be conducted for the proposed development of the off-site infrastructure areas. ENGEO Response to Off-Site Feasibility Report Comment We concur with BSK; a design-level geotechnical report should be conducted for the proposed development of the off-site infrastructure areas. Based on review of the Vesting Tentative Map prepared by CBG and conversations with the project team, we understand that the grading design for the drainage swale, bioretention basin, culvert, and storm drain will be deferred to a later stage of the planning submittal process. We can provide our design-level geotechnical recommendations for those areas once grading plans for those areas are finalized. BSK Comment 20 – General comment for the geotechnical report and off-site feasibility report The City should require the project Owner to retain ENGEO (the Geotechnical Engineer -of- Record for this project) to review the geotechnical/earthwork aspects of the project plans and specifications before they are finalized and issued for construction. The purpose of this review would be to allow ENGEO to confirm that the recommendations presented in the geotechnical report have been properly incorporated into these documents. The City should also require the project Owner to retain ENGEO during construction of the planned improvements to provide earthwork observation and testing services. We believe this approach is essential to the successful construction of this project. In the event ENGEO is not retained by the Owner of the project to provide earthwork observation and testing services during construction, the City should require the engineering consulting firm providing such services to: A. Review the geotechnical report and any supplemental documents issued by ENGEO, and review the project plans and specifications. B. Issue a letter signed/stamped by a California Registered Civil Engineer or a Registered Geotechnical Engineer stating that they are taking over the role of Geotechnical Engineer-of- Record for the project. This letter should also indicate whether the engineering consulting firm takes any exception to the recommendations provided by ENGEO and whether they have supplemental recommendations for the project. ENGEO Response to Comment 20 We concur that the geotechnical engineer of record (GEOR) should perform plan reviews on the civil and structural plans for conformance with the project geotechnical report, and that the GEOR should be retained during construction.
