STABILITY FEATURES AND CONDITIONS
- Adequate mapping, sections and description dimensions and type of existing downslope movement, soil or rock creep, flows, falls, slumps, slides, if any.
- Activity, cause or contributing factors of downslope movement features.
- Recent erosion, deposition, or flooding features.
- Subsidence or settlement, piping, solution or other void features or conditions.
- Groundwater and surface drainage characteristics or features.
- Surface expression (past and present) permeability or porosity of near surface materials.
- Actual or potential aquifers or conduits, perching situations, barriers or other controls to percolation and groundwater movement and fluctuations of groundwater levels at the site.
- Footing depth and width.
- Criteria for foundation material preparation.
- Allowable bearing values based on testing.
- Lateral pressures (active, passive, or at-rest conditions) and coefficent of friction.
- Ground preparation (clearing, unsuitable material removal, scarification and moisturization).
- Fill support:
- Suitability and precompaction of in-situ materials (describe test results and other pertinent data to be used to determine suitability).
- Densification and moisturization or dewatering measures (equipment, surcharge, settlement monitoring, if applicable).
- Placement of fill:
- Material approval (on site, imported).
- Methods and Standards (ASTM standards or approved equivalent).
- Testing (ASTM Standards (D1556, D1557, D2167, D2922, D2937, D3017) or equivalent) and frequency of field density testing by vertical intervals and or volume of fill.
- Elimination of cut, fill or other different transitions beneath improvements.
- Opion as to adequacy of site for the proposed development (this opion should also be summarized in the first part of the report).
- Other pertinent geotechnical information for the safe development of the site.
- A signature, certification number, and stamp of a Professional Engineer, registered in the State of Texas, who by training, education and experience is qualified in the practice of geotechnical or soils engineering practices.

The link below will take you to an article that will explain the geotechnical soil report in a different way. It expands, and explains more in a laymans point of view, the geotechnical soil report. The man that wrote the article is a professional engineer, working in the geotechnical engineering industry.
