The consultant should provide recommendations for control of erosion/surficial deterioration for graded slopes with low cohesion near surface soil or bedrock geologic structure.

Any geologic structure (i.e., bedding, joints, fault surfaces etc.) should be Utilized in the stability analyses.

Strengths utilized in the stability analyses should be derived from laboratory tests on the material that is considered for hypothetical failure.

Representative geologic cross section(s) shall be developed for all slopes that have geologic structure and are analyzed for slope stability.

Laboratory testing for shear strength should be performed on water saturated samples.

The geotechnical report shall discuss and present soils engineering parameters. The minimum guideline requirements for soils engineering studies are as follows:

Each site must have a soils engineering study.

Soils engineering studies shall be based on adequate and sufficient laboratory testing which should consist of; but not necessarily be limited to, soil compressibility; shear strength; dry density and optimum moisture content; and expansion potential.

The potential for soil collapse must be evaluated.

Subsurface explorations for the soils engineering report should be shown on a plan with a scale sufficient to describe their location (not necessarily a $1" = 40' scale).

Recommendations for soil removal, foundation design, retaining wall design, slope stability (deep and surficial), compaction requirements and any other pertinent soils condition should be presented.

Liquefaction potential should be considered where applicable.
