At minimum, the logs should include: boring designations; SPT results; depths of strata encountered; percent core recoveries and rock quality designations (RQDs) of rock cores; date boring was drilled; groundwater information; types and descriptions of geomaterials encountered; comments or notes regarding voids, boulders, obstructions, or any other unusual subsurface conditions encountered.
E. 
A written report prepared and signed by the professional geotechnical engineer licensed in the Commonwealth of Pennsylvania performing the preliminary geotechnical investigation shall be submitted to the Township. The report should, at a minimum, include: a description of the existing surface and subsurface site conditions; a review of the site geology and geohydrology; a discussion of any slope movements, sloughs, landslides, rock falls, or mining on or adjacent to the site, and an evaluation of their existing and/or potential impact on the site; the test boring logs and laboratory test results and the to-scale boring location plan described above in § 22-304, Subsection 4. The report should also include preliminary geotechnical engineering recommendations regarding apparent limitations/constraints on grading for land development, including apparent stable grades for proposed cut slopes and fill embankment. Any general measures required to provide for long-term stability including, but not limited to, drainage requirements, benching, erosion protection, and subgrade preparation should also be discussed in the report. This preliminary investigation report will not be considered a detailed engineering evaluation of site grading. The Township Engineer shall review the report and shall provide a summary recommendation to the Planning Director and Planning Commission.
F. 
The amount of buildable area as defined in this chapter and the Zoning Ordinance [Chapter 27] may be adjusted depending upon the results of the preliminary geotechnical investigation and pending Township approval.
3. 
Pending the results of the preliminary geotechnical investigation, the Township's geotechnical engineer may request a comprehensive geotechnical investigation.
[Ord. 657, 4/9/2015]
1. 
Completion of a comprehensive geotechnical investigation shall be dependent upon the results of the preliminary geotechnical investigation. The intent of the comprehensive investigation is to determine the stability of proposed grading operations and develop detailed engineered measures to provide for long-term slope stability. Test borings extending to sufficient depths to evaluate proposed grading should be performed. Specifically, borings should be located at the toes (base) of proposed fill embankments supporting roads or structures, or are eight feet or greater in height and will be graded to a slope steeper than 4:1. Sufficient borings should be located in cut slope areas supporting roads or structures, or that is greater than six feet in height and will be graded to a slope steeper than 4.5:1. The borings should extend at least to bedrock surface, but must also extend to a depth of at least five feet beyond the anticipated cut depth.
2. 
Standard penetration tests (SPTs) should be conducted in all test borings at no greater than three-foot vertical intervals in the soil mantle of all borings in compliance with American Society for Testing and Materials (ASTM) Test Designation: D1586-84. Where SPT refusal on bedrock is encountered prior to reaching the required depth, continuous NX, NQ, or NQ-2 rock cores should be procured as required for the engineering analysis. Thin-walled steel (shelby) tube samples of relatively undisturbed soil samples should be procured from selected borings, if and where required for physical laboratory testing, to determine relevant soil properties for the engineering analysis.
3. 
Groundwater encountered in each test boring should be recorded during drilling operations and 24 hours after completing each boring.
4. 
The borings should be accurately located in the field, Ground surface elevations should be obtained at each boring The final boring locations and their ground surface locations must be shown on a to-scale topographical survey (in accordance to § 22-303) that includes existing contours and proposed site grading contours.
5. 
A suitable boring log should be provided for each boring. At minimum, the logs should include: boring designation; SPT results; depths of strata encountered; percent core recoveries and rock quality designations (RQDs) of rock cores; date boring was drilled; groundwater information (minimum zero hour and 24 hour readings); types and descriptions of geomaterials encountered; comments or notes regarding voids, boulders, obstructions, or any other unusual subsurface conditions encountered.
6. 
A professional geotechnical engineer licensed in the Commonwealth of Pennsylvania shall complete a quantitative geotechnical analysis of proposed cut slopes and fill embankments. At minimum, test boring and relevant laboratory soil or rock test results, site groundwater and surface water findings, anticipated surcharge and/or hydrostatic loads/conditions and any other factors affecting the proposed slopes should be included in the analysis. The geotechnical analysis must be based on a method accepted by the geotechnical engineering community, and that has been published in an accepted engineering textbook, journal, or proceeding. The analysis should ultimately provide a factor of safety (FS) against movement/failure of the proposed slope. A slope will generally be considered stable in the long term when the FS>1.5, unless special circumstances, as approved by the Township, should be allowed. Various slope/embankment construction scenarios can be analyzed by the engineer, but no proposed slopes/embankments indicating a FS less than that approved will be deemed acceptable.
7. 
The written report, prepared and signed by the professional engineer performing the geotechnical analyses, shall be submitted to the Township. The report should, at minimum, include a description of the existing surface and, subsurface site conditions, a review of the site geology and geohydrology; a discussion of any slope movements, sloughs, landslides, rock falls, or mining on or adjacent to the site, and an evaluation of their existing and/or potential impact on the site; subsurface profile drawings depicting all relevant parameters of the slopes that were analyzed; a discussion of the geotechnical analyses; conclusion(s) regarding the stability of proposed site grading; the test boring logs and laboratory test results; a copy of the calculations/computer output for the stability analyses; and the to-scale boring location plan described above in Subsection 4. The report should also include geotechnical engineering recommendations, as required for grades for stable cut slopes and fill embankments; drainage requirements, subgrade preparations; benching requirements; suitable fill material, compaction, and moisture requirements, erosion protection requirements, retaining structures, if necessary, and limitations or constraints to proposed slope construction. The report will be generally reviewed by the Township Engineer, who shall provide a summary recommendation to the Planning Director and the Planning Commission.
