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. 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 surficial geology of St. Johns County generally includes Pleistocene to Holocene age (recent) sediments. The surficial units primarily consist of undifferentiated, unconsolidated, fine to medium quartz sands with thin lenses of shell and clay of varying thickness These lenses are generally discontinuous and vary within short distances both horizontally and vertically. The Florida Geologic Survey (FGS) county geologic map for St. Johns County (1993) indicates the presence of Holocene age beach and dune deposits (Qbd and Qh), some with lagoonal organics and clay, along the coast, as well as outcrops of the variably lithified shell and sand coquina of the late Pleistocene Anastasia Formation. The undifferentiated sands and the Anastasia Formation collectively measure approximately 100 feet thick in the project area based on FGS logging (Scott 1988).

The Miocene age, Hawthorn Group lies unconformably below the undifferentiated sands of St Johns County. The sediments of the Hawthorn Group are composed of gray to green, plastic, phosphatic, sandy clay and marl, interbedded with lenses of phosphatic sand, pebbles, sandy limestone, and dolostone. The unit is between 50 and 200 feet thick in St. Johns County (Scott 1988).

2.2 MATERIALS ENCOUNTERED

The Intracoastal Waterway (IWW) Palm Valley South, Cuts SJ-8 through SJ-15, are located in one of the northernmost reaches of the channel in St. Johns County. The materials to be excavated consist of shoaling that has occurred since the St. Johns County IWW was last dredged in 2007- 2008. 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. New vibracores were collected in 2022 to characterize the shoaled material. The boring locations are shown in Plate 1 through Plate 4.

The materials to be dredged consist of poorly-graded very fine to medium-grained quartz sand, sand to gravel size whole and broken shell fragments, silt, silty sand, clay, and clayey sand.

Woody debris ranging in size up to whole submerged trees should be anticipated within the

Intracoastal Waterway Jacksonville to Miami- Maintenance Dredging, 12- Foot Project, Palm Valley, South Reach, 00 31 32 - Page 3 required dredge depth and allowable over depth. Rock was not encountered in any of the borings;

in situ rock, if encountered, is not required to be dredged.

This is an active navigation channel and trash and debris, such as ropes, anchors, aluminum cans, and plastic bottles from navigation activities are likely to be present in the materials 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

4.3 BORING LOG NOTES

All borings 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 at least 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.

4.4 INSPECTION OF RECOVERED MATERIALS

The material recovered from borings marked with a checkmark in Table 1 is available for inspection by prospective offerors at the Corps of Engineers District warehouse. The address and hours of operation for the warehouse are listed below:

Address: 3077 Talleyrand Avenue Jacksonville, 32206 Florida Hours: 7:00 am to 2:30 pm

The recovered materials will be available for inspection during normal business hours as noted above, except Federal holidays, during the entire bid period. Prospective offerors shall notify the project geologist at 904-232-1054 or Chief, Geology and Explorations Section at 904-232-1617 at least four (4) working days before the visit.

The following information will be required to schedule the visit:

(1) Project title;

(2) Specific borings or entire set which are to be viewed;

(3) Date, time, and duration of the visit;

(4) Name of the person(s) and company to view the borings; and

(5) Point of contact and phone number regarding the visit.

Prospective offerors shall record their material examination visit in a record book maintained at the inspection site.

It is strongly suggested that prospective offerors view the samples before submitting their bid.

4.5 BORING LOGS

Applicable boring logs are presented on the following pages.

The borings presented in this section are available new and historic borings within the project area. Some 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
