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

The federally authorized Sarasota County Coastal and Storm Reduction project, Lido Key entails the periodic nourishment of 1.6 miles of shoreline on Lido Key between R-monuments R-35 and R-44 with sand dredged from the Big Sarasota Pass ebb shoal.

3 CHARACTER OF MATERIALS

3.1 REGIONAL GEOLOGY

Sarasota County is within the Coastal Lowlands physiographic region of peninsular Florida. The topography reflects the marine terrace deposits origin, formed during the Pleistocene, when sea level rose and fell in response to the advance and retreat of the continental ice sheets. The melting of the last glacial event, starting approximately 20,000 years ago, marked the beginning of the Recent (in geologic time, the Holocene Epoch).

The resulting rise in sea level slowed and barrier islands and lagoons developed along most of Sarasota County’s gulf coast. Elevations within the county range from mean sea level along the gulf coast and lower Myakka River to a maximum of approximately 100 feet in the northeast portion of the county. Elevations increase from the west and southwest toward the northeast. The topography tends to be flat, with relatively steeper slopes in the vicinity of streams.

Surface and near surface sediments in Sarasota County consist of quartz sand, consolidated and unconsolidated shell beds, clays, limestone, and dolomite. These sediments range in age from Oligocene (38 to 22.5 million years ago) to Holocene (10,000 years ago to present).

3.2 THE LOCAL GEOLOGY

The prominent topographic features of the Gulf Coastal Lowlands within Sarasota County are scarps and terraces developed during Pleistocene sea level stands. There are four (4) terraces

HURRICANE AND STORM DAMAGE REDUCTION PROJECT

00 31 32 - Page 3 within Sarasota County. The Pamlico terrace is found at elevations of approximately 8 – 25 feet above mean sea level, the Talbot at 25 – 42 feet, the Penholloway at 42 – 70 feet, and the Wicomico at 70 – 100 feet. The scarps which separate the terraces are, for the most part, poorly defined.

The Sarasota County gulf coast consists of barrier islands, spits, and lagoons. These barrier islands were formed during the last 4000 to 5000 years, since sea level became reasonable stable. The barrier islands seen today represent the latest adjustment to changing conditions during this period of time. Barrier islands change size, shape, and position in response to both short-term and long-term conditions. Barrier islands can be “welded together, split into segments, become attached to the mainland, or even disappear completely.

Barrier islands require an abundant sand supply. Since present sea level has stabilized, there has been very little new sand being naturally added to the barrier islands in this area. The result is that portions of these barrier islands are being eroded. Most of the sand lost to erosion is being redeposited as spits at the end of the barrier islands, in the flood and ebb shoals of tidal inlets, or offshore.

3.3 MATERIALS ENCOUNTERED

A total of twenty-two (22) vibracores, as shown in Table 1, were collected in Big Sarasota Pass in two (2) Borrow Areas (C, and D) in 2012 and 2014. Many of the sediments within the Big Sarasota Pass ebb shoal were deposited from eroding local beaches. The encountered sediments within the dredging depths consist of poorly graded, fine-grained quartz sands with trace silt and varying amounts of whole and broken shell; rock is not anticipated to be encountered.

4 DEFINITIONS

5.3 BORING LOG NOTES

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 20 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.

5.4 INSPECTION OF RECOVERED MATERIALS

The material recovered from borings marked with a checkmark in Table 1 are 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

00 31 32 - Page 10

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.

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.
