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. The associated boring logs and laboratory data are presented in paragraphs 5.5 and 5.6, respectively. 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 PROJECT BACKGROUND

Big Fishweir Creek (BFWC) is a tributary on the west side of the St. Johns River, located approximately four miles south of Downtown Jacksonville (Plate 1). BFWC enters the St. Johns River just north of the Ortega River. Little Fishweir Creek (LFWC) is a tributary that drains into the lower portion of Big Fishweir Creek, approximately 1,500 feet from the mouth of BFWC.

Excessive sedimentation and poor water quality conditions burden BFWC and LWFC and have contributed to a loss in wetland, wildlife, and benthic habitats.

3 CHARACTER OF MATERIALS

3.1 THE LOCAL GEOLOGY

BFWC is located within the coastal lowlands physiographic region of northeast Florida, which runs parallel to the coastline and extends from the Atlantic Ocean to just west of Downtown Jacksonville. Geologic formations in BFWC area consist of undifferentiated surficial deposits, consisting of sand, clay, shell and limestone from ground surface to a depth of 20 to 120 feet. The undifferentiated deposits overlie the Hawthorne Formation, an intermediate confining unit consisting of phosphatic sand, silt, clay, limestone and dolomite that has a thickness of 100 to 500 feet. The Hawthorne Formation overlies the Ocala Limestone, consisting of chalky to granular marine limestone. The Ocala Limestone comprises the Upper Floridan Aquifer and is 100 to 350 feet thick.

3.2 MATERIALS ENCOUNTERED

Big Fishweir creek has never been dredged. Vibracores were collected in 2019 within the proposed dredge template. The vibracore locations are listed in Table 1 and depicted in Plates 2 and 3. Laboratory testing results are summarized in Table 2.

00 31 32 Page 3

The materials to be dredged consist of unconsolidated poorly-graded quartz sand (SP), silty sand (SP-SM, SM), clayey sand (SC), super-saturated silt (MH, OH) with varying amounts of sand to gravel-sized shell and organic peat (PT) with moisture contents up to 500%. Large pieces of submerged wood, likely roots and whole trees, were also encountered during the geotechnical investigation. Submerged trash and debris, such as large household items, furniture, bottles, cans and navigation items are present within the dredging template.

4 DEFINITIONS

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

4.1 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.

Hydrometer testing is available for this dataset. Results are depicted in the graphs included in section 5.6.

5.3 BORING LOG NOTES

Borings VB-BFWC19-01 through 18 were sampled using a Rossfelder P3 electrical vibracoring machine that was mounted on a small shallow-draft barge. A generator with an electrical vibrator was attached directly to a three-inch diameter steel core barrel and lowered to the creek bed through a moonpool in the deck of the sampling platform by attaching lengths of drill stem. The sample barrel was allowed to penetrate the creek bed until it reached the target depth 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.

5.4 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) 232-1140 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.

5.5 BORING LOGS

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. Accordingly, prospective offerors shall form their own conclusions from the examination of the recovered materials prior to submission of their offer.
