(continued] LGC Valley believes that we have prepared a reasonably conservative approach for a site investigation in terms of excavations such as borings and test pits, laboratory testing of site soils to determine their characteristics such as shear strength, expansion potential, and bearing capacity, and the creation of maps and cross sections and other relevant figures to convey the geological conditions that exist at the site. The information gathered from our field work will result in our interpretations and conclusions concerning the site conditions and these interpretations will be reviewed in light of the proposed design. Ultimately, our combined efforts will lead to'various geotechnical options to mitigate those physical conditions that require engineered support. We anticipate'reviewing these options with the design team and the Conejo Recreation and Park District in order to assess which options are most feasible from a design, construction, safety and cost perspective. In the end, LGC Valley will prepare a geotechnical report that indicates the scope of work, our findings, interpretations, conclusions and recommendations for the Lang Ranch Community Park. The document will be formatted such that it can be assessed by the various reviewing agencies. The report will be useful as a bidding document for grading of the site as it will contain all site recommendations for grading including monitoring during construction and excavation control, data relevant for construction of foundation elements, wall design information, and general to specific construction techniques in order to keep the site safe from potential unwanted and dangerous earth movements. Please note as part of the geotechnical report, due to the existing geotechnical/geologic conditions of the site (i.e. presence of a landslide), we will provide a series of geotechnical monitoring options that we believe help reduce the potential for short and long term exposure to unwarranted and unnecessary liability and litigation from adjacent sites. Based on our experiences with similar sites under similar scenarios, the following are examples of monitoring options that should be considered: a crack survey of streets and sidewalks in nearby neighborhoods, installation and surveying of survey monuments, and installation and monitoring of slope inclinometers (along Westlake Boulevard). These monitors will provide early warning for potential slope instabilities that can then be readily contained. In addition, they help to show that no movement of the landslide has taken place during the grading operations on the site, thus reducing the potential exposure to unwarranted and unnecessary liability and litigation from adjacent sites.
