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 surficial samples. The associated boring logs are presented in paragraph 4.4. 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

Martin County falls within the Atlantic Coastal Province physiographic unit and is part of the Eastern Flatland Region which was formed during the inundation and subsidence of recent ice ages and the respective oceanic submergence and emergence. The surficial sediments consist of sands, silts and clays of Holocene to recent age. Those surficial deposits are underlain by the Anastasia formation, which is composed of interbedded sands and coquina limestone. The coquina limestone is almost entirely comprised of whole and fragmented mollusk shells, is lightly to moderately indurated and of orange-brown color. The interbedded, unconsolidated to lightly-cemented sand layers are gray to orange-brown in color and can contain fossils. The Anastasia Formation is followed by the sediments of the Pleistocene-age Fort Thomson formation and subsequently by the Pliocene Tamiami Formation. Lithologically these sediments are varying from unconsolidated fossiliferous quartz sands to well-indurated, sandy, fossiliferous limestone. Clayey sands and sandy clays are also present. The Pleistocene and Pliocene sediments have a thickness of 50 to 200 feet and form part of the surficial aquifer system.

2.2 THE LOCAL GEOLOGY

The Okeechobee Waterway is a federal navigation channel located within the St. Lucie River, connecting Lake Okeechobee to the Atlantic Ocean through the St. Lucie Inlet in Martin County, Florida. The shoreline along the OWW is bounded by mangroves and residential homes.

2.3 MATERIALS ENCOUNTERED

Reaches 3 and 4 of the OWW have not been dredged since the mid 1970’s. The materials were described during geotechnical investigations in 2000 consisting of core borings and 2020 consisting of surficial samples.

Maintenance Dredging 8-Foot Project

00 31 32 - Page 3

The materials to be encountered during dredging consist primarily of soft silt and clay, with varying amounts of fine to medium grained quartz sand, whole and broken shell fragments ranging in size from sand to fine gravel and both leafy and woody plant matter.

3 DEFINITIONS

Definitions not explicitly indicated in the sections below are typical industry standard definitions from their respective ASTMs.

3.1 DEFINITIONS OF BASIC TERMS

Carbonate – Soil component that reacts with HCl of an indeterminate origin (shell, rock, etc.).

Fill – Material that has been placed by man, described with all soil characteristics.

Layer – Rock or soil with a thickness of 6 inches or less.

Lens – A geologic deposit of variable thickness, which disappears laterally in all directions and cannot be correlated to adjacent borings.

4.2 BORING LOG NOTES

Borings from 2000 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-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 was encountered, the borings were continued with a 4-inch by 5 1/2-inch diameter core barrel until the rate of penetration indicated softer material, at which point the SPT procedure was resumed.

Surface Samples collected in 2020 were collected with an AMS 6”x6”x6” clam shell sampler which weighs approximately 25 pounds. The sampler was tied to nylon rope and mounted on a shipboard winch with pulley. During sampling, the clam shell was allowed to free-fall from the winch at the target location.

4.4 BORING LOGS

Applicable boring logs are presented on the following pages.

The borings presented in this section are available historic borings within the project area. The current elevations of the materials at these locations are shown on the contract drawings.

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.
