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 5.6 and 5.7, 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

Since 2006, Gasparilla Island beaches were nourished using sand from an off-shore sand source adjacent Boca Grande Pass, named Gasparilla Shoal. Gasparilla Shoal was utilized for the first time in 2006 by the non-federal sponsor for Gasparilla Island Beaches in response to the 2004- 2005 hurricane season. The sand source provided beach compatible sand with no sediment compliance/compatibility issues. This offshore sand source was also utilized in 2013 in order to stabilize the beaches after storms in 2012.

3 CHARACTER OF MATERIALS

3.1 REGIONAL GEOLOGY

The Florida Peninsula occupies a portion of a much larger geologic unit called the Florida Plateau.

Deep water in the Gulf of Mexico is separated from the deep water of the Atlantic Ocean by this partially submerged platform nearly 500 miles long and 250 to 450 miles wide. Since the Mesozoic Era, approximately 200 million years BP (before present), the plateau has been alternately dry land or covered by shallow seas. During that time up to 20,000 feet of carbonate and marine sediments were deposited in central and southern Florida. Either following or concurrent with one of the later periods of emergence, there appears to have been a tilting of the Florida Plateau about its longitudinal axis. The west coast was partially submerged, as indicated by the wide estuaries and offshore channels, while the east coast was correspondingly elevated, showing the characteristics of an emergent coastline.

During the last million years, a series of four glacial periods, or ice ages, brought about significant changes in sea level. As a result of these sea level fluctuations, the Florida peninsula was again covered and uncovered by shallow seas. Following the first glacial period, sea level rose approximately 270 feet above its present level. Dry land on the Florida peninsula was then restricted to a few small islands along the central Florida ridge and in northeast Florida.

00 31 32 - 3

Approximately 100,000 years ago, the last glacial period began. Sea level fell to approximately 300 feet below its present level and the Florida Plateau emerged as dry land. Approximately 15,000 years ago, sea level began its most recent rise towards present sea level. Sea level rose at an average rate of 30 feet per 1,000 years. About 7,000 years ago, the rate of sea level rise slowed when the sea level was about 30 feet below its present level. It was at this most recent slowing of sea level rise that the modern barrier islands of southeast peninsular Florida formed.

3.2 THE LOCAL GEOLOGY

Lee County, in southwest Florida, covers approximately 803 square miles. Its boundaries are formed by Charlotte County on the north, Hendry and Collier Counties on the east, and Collier County on the south. The shoreline of Lee County consists of a series of barrier bars broken by numerous inlets. The shoreline is further characterized by sandy barrier islands backed by shallow bays, marshes, and mangrove areas. The coastal plain in the vicinity of San Carlos Bay and Estero Bay is of low relief and low elevation. The Caloosahatchee, Peace, and Myakka Rivers all drain the estuary system. The barrier islands of Lee County are believed to have been initially formed around 4,400 years ago and prograded seaward. A reduction in the rate of Holocene sea level rise at that time, combined with a local sand supply and pre-existing topography, helped in the location and formation of the present barrier island chain.

Gasparilla Island lies west of the Charlotte Harbor estuary system and is bound to the north and south by Gasparilla Pass and Boca Grande Pass, respectively. Gasparilla Island is a 6.7 mile long narrow barrier island with a relatively stable northern shoreline and increasing erosion towards the southern end. High southerly net sediment transport rates along Gasparilla Island result in the well-developed ebb-tidal delta system of the Boca Grande Pass.

3.3 MATERIALS ENCOUNTERED

The materials within the dredging template primarily consist of fine- to medium-grained quartz sand that is poorly-graded and contains trace to some whole and broken shell up to 3”. No rock was encountered in any of the borings.

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.

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 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.

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