Scope 'of Geotechnical'Services eco of r4l$_ :okF The following is the scope of geotechnical services for development of the 2045 .Royal Avenue design and construction documents for the proposed Lang Ranch Park site. Suite 125 Simi Valley, California 93065 Background Review P S O M AS LGC- will perform a background review of the site from a geotechnical perspective. A background review is of paramount importance in determining 'the anticipated geologic conditions at the site and is the first step toward the planning of the field investigation. The study will consist of a review of the following: Available geotec cal.reporis and geologic literature, maps and other readily available relevant materials pertinent to the site within the City of Thousand Oaks and County of Ventura archives; and LGC's in- house library. LGC also request any documents that the. District may have in the District's possession or know of that may benefit LGC's research. A review of aerial photographs of the site to review the changes to the site over time. ► Work with the 2nd Party Consultant to review and assess the scope of work proposed by LGC and modify where deemed appropriate. Geotechnical Field Investigation LGC' pose to provide personnel, equipment, and materials to explore the surface and near -subsurface conditions, perform geotechnical laboratory testing, provide geotechnical engineering analyses, and prepare geotechnical recommendation options for.the.project, as necessary. Our recommended geotechnical remedial options will. be formulated to help maintain (from a geotechnical poiaC of view) that the final design of the Lang Ranch Park to be as close as possible to the original approved Master Plan Design. This study does not include an evaluation of the potential for soil and/or groundwater contamination at -the site. It is anticipated that the 2nd Party Consultant will spend time with LGC concurrently in the field to review and assess the observed conditions. We anticipate that the majority of their time will be spent with the large diameter borings for hands-on evaluation of the site soils. Geotechnical tasks are described further in the following subsections. Exploration ► LGC will perform a geological reconnaissance of the site and surrounding area.. LGC geologists will geologically map the site to determine the fill/alluvium/landslide/bedrock contacts at the site, to Scope of Services I LGC Geotechnical — 30
