3.3.5 Discussion of unusual conditions encountered during field drilling and <br />sampling. <br />3.4 Analysis of Site Investigation Data. <br />3.4.1 Summary of observed subsurface profile (stratigraphy);discussion. of <br />soil and rock layers and deposits encountered in the subsurface investigation; index <br />properties and classifications. <br />3.4.2 Comparison of developed soil profile to geologic setting described in <br />previous section, including a discussion of similarities and differences. <br />3.4.3 Discussion of each of the potential geologic-natural hazards observed <br />at the development site; location, magnitude, time effects, possible effects on the <br />structure or facility. <br />3.4.4 Description of potentially expansive clays, organic deposits, loose <br />sands, and other unstable soils found on site. <br />3.4.5 Discussion of anticipated groundwater conditions that may effect the <br />site development and/or project, and discussion of effects of grading on infiltration <br />of water. <br />3.5 Conclusions. Include the same requirements required in a~Level 1 and the <br />following: <br />3.5.1 Suggested methods for dealing with the potential geologic-natural <br />hazards; qualitative advice to design engineers or architects. <br />3.5.2 Cleaz reference to empincal, published or unpublished, minimum <br />design standards or procedures for the design of elements of the structure or facility, <br />which aze based solely on the index properties of supporting soil and/or rock units. <br />Recommendations for design and construction shall be based on engineering <br />judgment, combined with experience. <br />3.5.3 Expectations concerning consolidation or settlement. <br />3.6 Appendices and Graphic Presentations. Shall meet the same requirements <br />required in a Level 1 and include the following: <br />3.6.1 Plot plan showing locations of borings and test pits. <br />3.6.2 Logs of borings and/or observations pits, including all sampling data <br />. and water level measurements. <br />3.6.3 Soil profile drawing showing estimated stratigraphy and the locations <br />of field samples and observed water levels. <br />3.6.4 Map showing boundaries of units. <br />3.6:5 Map showing areas of potential geologic-natural and/or seismic <br />hazards, if any (by inclusion or by reference in body of text). <br />3.7 Seal and Si~rlatures Required. A Leve12 report shall be signed and sealed by <br />a. Qualified Registered Professional. The report writer may quote from, or make reference <br />to, any published or unpublished, empirical minimum design standards that use only <br />soiUrock descriptions and/or classifications and that are applicable to the structure or facility. <br />Design recommendations contrary to minimum building code and approved city design <br />parameters shall be sealed and signed by a Geotechnical Engineer. <br />4. Review and Determination. No further geological and geotechnical investigation <br />is required when the following conditions have been satisfied: <br />4.1 Groundwater elevations will not impact construction activity or will not <br />Administrative Order -10 <br />rladminordwles\02geotechlao.wpd(09/05/02) <br />
