1. Perform a geotechnical investigation and provide a comprehensive report as described in the current California Building Code (CBC), Chapter 18, and as described below 2. Boring quantities, locations and depths shall be of sufficient depth and in appropriate locations per specific project needs and best industry practices for local conditions and in conformance with building code requirements 3. Review existing records and report on previous uses of the site that may impact the new construction. Provide historical information regarding existing site geology including areas of known fill placement. 4. Provide seismic design parameters (including site specific ground hazard analysis in accordance with ASCE 7-16 chapter 21.2) as described in the current edition of the CBC Chapter 18 for Seismic Design Categories D, E, and F. 5. Provide groundwater levels of site, both historic and as-measured. 6. Provide infiltration feasibility of existing soils for water quality requirements including: a. Shallow Soil Percolation Tests – Bore two or more holes 7 to 10 ft deep, place perforated PVC pipe surrounded by a backfill of No. 3 sand, fill with water and record water level over time and for at least three cycles to help establish infiltration properties of the surrounding soils. b. Recommended proximity of infiltration to existing structures
