GEOTECHNICAL DATA REPORT

1 SCOPE

The information provided in this section encompasses the geotechnical field investigations available for this project. The investigations consist of borings and hand augers. The associated boring logs are presented in paragraph 4.5. A character of materials paragraph is included to provide a comprehensive description of the materials utilizing both recent and historical knowledge of the project area. Also included in this section are definitions of terms and boring log notes, which provide additional explanation of the boring logs and drilling techniques.

Items discussed in the character of materials paragraph may not appear explicitly on the boring logs. Based on historic knowledge of the project area, the character of materials paragraph includes items that supplement the data documented by the boring logs. When reviewing the boring logs, use all of the data on the logs, including the materials description, legend, and blow counts. When evaluating the subsurface conditions, use all of the data, including the character of materials paragraph and boring logs.

During the solicitation period, any questions that pertain to the information provided in this section should be addressed to the contract specialist identified in Block 9 of SF1442. After contract award, questions should be addressed to the appointed ACO/COR, which will coordinate with Geotechnical Branch.

2 CHARACTER OF MATERIALS

2.1 REGIONAL GEOLOGY

The regional geologic conditions of Biscayne Bay Coastal Wetlands are mainly influenced by the units encountered within the Pliocene to Pleistocene Biscayne Aquifer sediments. The Biscayne Aquifer is a hydrologic unit of water bearing consolidated sediments and limestone composed of parts or all of the following formations: (1) Lake Flirt Marl; (2) Miami Limestone (Miami Oolite); (3) Anastasia Formation; (4) Fort Thompson Formation (the southern part); and (5) Caloosahatchee Marl (relatively insignificant erosion remnants and isolated reefs).

The Lake Flirt Marl is up to 6 feet thick, relatively impermeable, and composed primarily of calcareous mud with some areas of dense limestone. The Lake Flirt Marl underlies the organic (peat) soils throughout much of the Everglades and coastal marshes.

The Miami Limestone underlies the Atlantic Coastal Ridge to the south, beyond Florida City. The formation is present on the floor of Florida Bay, and reappears above the water level in the lower Florida Keys from Big Pine Key to Key West. It is thickest along the coast, reaching a maximum thickness of 40 feet, but its base is seldom below 20 feet below sea level. The oolitic limestone is cross-bedded to massive, white to yellow, and often contains quartz sand that fills solution holes and channels. These solution holes are mostly vertical and give it an exceedingly high vertical permeability. Hydraulic conductivity values for the Miami Limestone in the vicinity average over 8,000 feet per day.

The Fort Thompson Formation consists of alternating beds of marine, brackish, and freshwater limestones. The formation overlies the Caloosahatchee Marl. The thickness of the formation is about 40 feet in eastern Miami-Dade, Broward, and Palm Beach Counties, and increases in thickness to the south and east. The hydraulic conductivity of this formation is extremely high, exceeding an average of 40,000 feet per day. This formation covers the greatest geographical expanse of all Quaternary formations in southern Florida.

Section 00 31 32-3

The Anastasia Formation is considered to be contemporaneous with the Fort Thompson Formation, exhibiting a thickness of approximately 40 feet in east-central Miami-Dade County.

This formation can be divided into two distinct facies: a coquina facies and a shell rock facies.

The coquina facies represents a high-energy environment typical of an offshore bar complex and generally is aligned with the present coastline. The shell rock facies is found behind the coquina facies, between the offshore bar complex and the shoreline.

The transition between the Tertiary Pliocene and the Quaternary Pleistocene occurs in the upper members of the Caloosahatchee Formation. The Caloosahatchee Marl is composed of sandy marl, clay, and silt-size particles interbedded with shell beds. Within the Biscayne Bay Coastal Wetlands, the Caloosahatchee Marl is thin because of erosion, whereas in some places it is absent or appears only in isolated patches.

2.2 MATERIALS ENCOUNTERED

Levee fill is the first material encountered in the vicinity of the proposed culvert and pump station.

The materials of the L31E levee are composed of compacted sand to boulder-sized limestone, fine to medium quartz sand, and organic silts and clays. Below the levee fill, the top of natural ground typically consists of a brown, soft, sandy, lean organic silt. This silt layer ranges from 0.0 to 4.0 feet thick. Limestone dominates under the silt layer to the terminal depth of the deepest boring. The limestone is oolitic, fossiliferous, moderately hard to hard, moderately to heavily weathered, thick bedded, very porous and highly transmissive. The hardness of the limestone is variable across the project sites and areas of more resistant rock are likely to be encountered.

This limestone is found to be interbedded with multiple layers of dense to loose, poorly cemented, fine grained quartz sand. The sand layers range from 2 to 10 feet in thickness. The water table is typically encountered within five (5) feet of the natural ground surface and fluctuates as a result of the change in seasons, isolated storm events, and/or localized dewatering of nearby canals.

Groundwater levels are often very close to or above the ground surface during the wet season.

4.3 BORING LOG NOTES

Borings were driven using the Standard Penetration Test (SPT) procedure with a 140 pound hammer with a 30-inch drop using a 2.0 foot split spoon (1 3/8-inch I.D. and 2-inch O.D.). Borings were advanced in 18 or 24-inch intervals, or until refusal was encountered. Refusal is defined as a total of 50 blows of the hammer within any 6-inch increment, a total of 100 blows within any 1-foot increment, or no observed advance of the sampler after 10 successive blows of the hammer.

When refusal or competent rock was encountered, the borings were continued with a 4-inch by 5 1/2-inch diameter core barrel or PQ wire line until the rate of penetration indicated softer material, at which point the SPT procedure was resumed.

All SPT borings cored rock with a 4-inch by 5 1/2-inch diameter core barrel, with the exception of borings CP16-BBCW-CB-1 and 2, which utilized PQ wireline.

Borings CP16-BBCW-AB-1, and 3 through 7 were sampled with a hand auger.

Applicable boring logs are presented on the following pages.

While the Government’s borings are representative of subsurface conditions at their respective locations and vertical reaches, local variations in the characteristics of the subsurface materials of this region are to be expected.
