GEOTECHNICAL DATA REPORT

1 SCOPE

The information provided in this section encompasses the geotechnical field investigations available for this project. The investigations consist of vibracore borings and surface samples. The associated boring logs and laboratory data are presented in paragraphs 4.5 and 4.6 respectively.

A character of materials paragraph is included to provide a comprehensive description of the materials utilizing 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.

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 Geosystems Branch.

2 CHARACTER OF MATERIALS

2.1 THE LOCAL GEOLOGY

The project is located in the federal navigation channel between the barrier island and beach on the Atlantic Ocean and the mainland in northern St. Johns County, in the Atlantic Coastal Plain physiographic unit. The regional geology of St. Johns County for the Quaternary and upper Tertiary Systems range in age from Recent to Pleistocene to Miocene age sediments. The Recent to Pleistocene age sediments are undifferentiated and cover the entire county and consist of: fine to medium quartz sand and thin lenses of shell and clay of varying thickness. These beds are generally discontinuous and vary within short distances both horizontally and vertically. The shell beds thicken and can become consolidated along the coast and form coquina of the late Pleistocene Anastasia Formation. These sediments occur at land surface and have an average thickness of 50 feet. These deposits lie conformably with the sediments of the Upper Miocene/Pliocene sediments. The Miocene/Pliocene sediments are comprised of interbedded layers of marine, fine to medium sand, shell and green, calcareous, silty clay. These sediments vary in thickness (20-75 feet) throughout the county,and have an overall trend to thicken to the east.

The Hawthorn Formation is of middle Miocene age, lies unconformably below the Upper Miocene/Pliocene sediments which underlies all of St Johns County. The sediments of the Hawthorn Formation are composed of gray to green, plastic, phosphatic, sandy clay and marl, interbedded with lenses of phosphatic sand, pebbles and sandy limestone. The formation is between 50 and 200 feet thick

2.2 MATERIALS ENCOUNTERED

The materials to be excavated consist of shoaling that has occurred since the St. Johns County IWW was last dredged (2009). The newly deposited sediments can be expected to be similar to the materials shown in the historic boring logs since the depositional environment of the channel has not been altered significantly since it was last dredged.

The Intracoastal Waterway (IWW) Cuts SJ-1 through SJ-7 are located in the northernmost reach of the channel in St. Johns County. Vibracore borings were collected in 1999 to characterize the materials encountered within Cuts SJ-1 to SJ-9 of the IWW in the vicinity of Palm Valley. The recovered materials consisted of poorly-graded fine to medium-grained quartz sand with varying

Intracoastal Waterway Jacsonville to Miami- Maintenance Dredging, 12-Foot Project, Palm Valley, North Reach, 00 31 32-3 amounts of silt and some whole and broken shell fragments. The sediments also consist of some layers of dark-colored inorganic and organic silts with detrital vegetation as well as inorganic clays.

Rock was not encountered in any of the borings; in situ rock, if encountered, is not required to be dredged.

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.

Rock – A naturally occurring substance composed of one or more minerals bound together. This geologic term includes a range of engineering properties: strength, hardness, permeability, weathering, and discontinuity. These properties are noted or can be inferred from the boring logs as blow counts, penetration rate, RQD, hardness, etc.

4.3 BORING LOG NOTES

Borings CB-IWWSJ99-1 to CB-IWWSJ99-20 and CB-IWWSJ99-22 to CB-IWWSJ99-60 were sampled using an Alpine style, pneumatic vertical hammer, vibracore drilling apparatus having a continuous 20-foot by 3 or 3 1/2-inch core barrel with clear plastic core liner that was advanced until a depth of 10 feet was reached or until refusal was encountered. Refusal is defined as no additional penetration of the vibracore with two minutes of additional effort applied to penetrate through the resistant layer at maximum vibration.

Surface sample CB-IWWSJ99-21 was collected with a 4”x12” 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.

4.5 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. Most of the materials within the project template presented on the boring logs have been removed by previous dredging events with subsequent shoaling of similar materials. 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
