and construction difficulties. 2.2.7 Measure slopes in the project area. 3. Report Content. 3.1 Introduction: 3.1.1 Purpose and scope of investigation. 3.1.2 Client or party that commissioned the report. 3.1.3 Authorization for study. 3.2 Prol ect Location and Description: 3.2.1 Site location and description, including topography, slopes within and adjacent to the project. 3.2.2 Description of proposed development, structures, and/or facilities. 3.2.3 Description of previous investigations, existing or previous structures on the site, project file data, and anecdotal information from residents, as applicable. 3.2.4 Geologic setting -- discussion, based on literature survey, of the local surficial geology that may affect the project and potential geologic-natural hazards, including potential seismic hazard. 3.2.5 Site reconnaissance observations -- topography; slopes; exposures; condition of on-site and adjacent structures; drainage features, vegetation. 3.3 Conclusions. 3.3.1 Summary of site subsurface soil/rock conditions, based on literature survey and site reconnaissance. 3.3.2 Indications of the absence or presence of potentially expansive soils, organic deposits, loose sands, and other unstable soils at critical locations with respect to the structure or facility. 3.3.3 Recommendation for acceptance of site without further investigation or recommendations for making a higher level of investigation, with reasoning for the recommendation. 3.4 Appendices. 3.4.1 Site location map. 3.4.2 Map showing areas of potential geologic-natural and/or seismic hazards, if any (by inclusion or by reference). 3.4.3 Map showing contours, drainage features, seeps, springs, wetlands, open waterways. 3.4.4 Grading Plan. 3.4.5 Footnote or bibliography references to pre-existing information, including published literature, geologic maps, and other applicable resources. 4. Review and Determination. Further geological and geotechnical investigation is required when one of the following circumstances exist: 4.1 The analysis reveals evidence of existing or potential stability problems; 4.2 In the Qualified Registered Professional's opinion, site conditions such as springs, seeps, depth of soil to bedrock, variations in soil types, or a combination of these conditions will impact the design parameters of the structure.
