Veco Design Studio <br />June 3, 2024 <br />Project 10112-04 <br />Page 2 <br /> <br />d) The California Geological Survey Special Publication 117A states liquefaction <br />analysis is required for: <br /> <br />Structures for human occupancy, with the exception of either of the following: (A) <br />Single-family wood-frame or steel-frame dwellings to be built on parcels of land <br />for which geologic reports have been approved pursuant to paragraph (1). (B) A <br />single-family wood-frame or steel-frame dwelling not exceeding two stories when <br />that dwelling is not part of a development of four or more dwellings. <br /> <br />e) Since the existing structure or proposed ADU will not exceed two stories, a <br />detailed liquefaction analysis is not required for this project. However, we <br />provided recommendations for the structure to be designed to reduce the effects of <br />liquefaction. <br /> <br />f) No subsurface exploration, except for our observation of a shallow test pit in the <br />proposed improvement area, was conducted during the course of preparing this <br />report. However, we presume that the stability of the underlying soils has been <br />assessed and approved in conjunction with the development of the tract and the <br />residence. Detailed analysis of the fill settlement was beyond the scope of our <br />work. <br /> <br />g) Evaluation of the structural and geotechnical aspects of the existing residence and <br />other structures was beyond the scope of our services. The soils present below the <br />planned construction were not investigated, and therefore the quality of the soils <br />is not known. It is possible that the subgrade soils may impact the future <br />performance of the planned addition. <br /> <br />h) This report is subject to the Terms and Conditions enclosed to this report and <br />incorporated herein by reference. <br /> <br />2. SCOPE <br /> <br />The scope of services we provided was as follows: <br /> <br />a) Preliminary planning and preparation; <br /> <br />b) Review of available geologic maps covering the site area; <br /> <br />c) Site visit to observe the existing conditions; <br /> <br />d) Excavating a shallow test pit within the proposed ADU area; <br /> <br />e) Collecting a representative soil sample for soil classification and laboratory <br />testing; <br />
