Appendix_6_-_Geotechnical_Report.pdf

APPENDIX OVERVIEW

Introduction: These appendices contain geotechnical data collected to assist Pinellas County in applying for federal and state permits related to the dredging of Grand Canal and a deposition basin

(Basin A) adjacent to the navigation channel. In 2021, three (3) vibracores and eleven (11) grab samples were collected within the investigation area in Shell Key, which is located between Pass-a-

Grille and Bunces Pass in Pinellas County. A total of fifteen (15) vibracore sub-samples were collected during processing of cores. The vibracore data are provided in the form of logs, photographs, granularmetric reports, grain size distribution curves/histograms and carbonate test results. The grab samples data are provided in the form of granularmetric reports, grain size distribution curves/histograms and carbonate test results.

1) 2021 APTIM Vibracore Logs

This appendix contains three (3) vibracore logs. Laboratory and descriptive information for each vibracore is presented on the log sheets. Unified Soils Classification System terminology is used in the core layer descriptions and key grain size information (mean grain size, fines content and sorting) for each vibracore sample is presented under the Remarks column. Multiple layer intervals are sometimes represented by a single sample. The Box or Sample column is used to identify the specific sample that represents a specific layer.

2) 2021 APTIM Vibracore Photographs

Photographs of the three (3) vibracores are presented in this appendix.

3) 2021 APTIM Vibracore Samples Individual Granularmetric Reports

This appendix contains individual granularmetric reports for the vibracore samples collected.

4) 2021 APTIM Vibracore Samples Individual Grain Size Distribution Curves/Histograms This appendix contains individual grain size distribution curves/histograms for the vibracore samples collected.

5) 2021 APTIM Grab Samples Individual Granularmetric Reports This appendix contains individual granularmetric reports for the grab samples collected.

6) 2021 APTIM Grab Samples Individual Grain Size Distribution Curves/Histograms

This appendix contains individual grain size distribution curves/histograms for the grab samples collected.

7) 2021 APTIM Vibracore and Grab Samples Carbonate Testing Results This appendix contains the vibracore and grab samples carbonate testing results.

8) Composite Summary Tables A series of summary tables are presented in this appendix. These tables are used to calculate and summarize composite data. Composite statistics were calculated based on the vibracore samples that are representative of the material defined within the Grand Canal Basin A. Composite data provide the average physical characteristics of the borrow area. An average of the representative layers, weighted by effective length, was calculated for each vibracore, producing the vibracore composite. The vibracore composites were averaged and weighted by effective length to calculate the basin composite.

Three table types were produced to display this data. The Composite Summary table is a summary of key grain size data for all of the composites. The Composite Data table shows the composite data for the borrow area and the supporting composite vibracore data used to calculate the borrow area composite. The Cumulative Percents and Computed Distributions table shows the weighted average percent retained on all sieves for the individual samples used to create vibracore composites.

9) Composite Granularmetric Reports Composite granularmetric reports, corresponding to data presented in the tables in Appendix 8, are included here. Granularmetric reports are presented for the Grand Canal Basin A and each vibracore.

10) Composite Grain Size Distribution Curves/Histograms Composite grain size distribution curves/ histograms, corresponding to the data presented in the Appendix 10 tables, are included here. Curves and histograms are presented for the Grand Canal Basin A and each vibracore.

Legend for Geotechnical Data

(SP), (SM), etc. Refers to the Army Corps of Engineers Unified Soils Classification System. Class types are defined primarily by grain size, sorting and percent of material passing the 200 sieve. Classification of materials on the core logs based on visual field examinations are identified on the core logs under the Classification of Materials Description. Classifications based on laboratory sieve analyses are identified on the core logs in the Legend and under Remarks.

Grain Size Terms

Cobble – retained on the 3.0” sieve Gravel – greater than the #4 sieve and less than the 3.0” sieve

Coarse: greater than the ¾” sieve and less than the 3.0” sieve Fine – greater than the #4 sieve and less than the ¾” sieve

Sand - greater than the #200 sieve and less than the #4 sieve Coarse - greater than the #10 sieve and less than the #4 sieve Medium - greater than the #40 sieve and less than the #10 sieve Fine - greater than the #230 sieve and less than the #40 sieve

Fines – (silt or clay) passing the #230 sieve

Descriptive Term Range of Proportions Sandy, gravelly, etc. 35 % to 50 %

Some 20 % to 35 % Little 10 % to 20 % Trace 1 % to 10 %

Proportional definition of descriptive terms
