GEOTECHNICAL DATA REPORT

1 SCOPE

The information provided in this section encompasses the geotechnical field investigations available for this project. The investigations were conducted by the project sponsor (Palm Beach County), consisting of core borings, auger borings, and mud probes, and may not conform to Government standards. 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 Geosystems Branch.

2 PROJECT BACKGROUND

The Lake Worth Lagoon (1135) CAP project is an Ecorestoration project within Lake Worth Lagoon, Palm Beach County. The project will use material from the DMMAs located on Peanut Island, Palm Beach County, to construct islands in the lagoon.

All data presented in the following pages were supplied by the project sponsor and may not conform to Corps of Engineers data standards.

3 CHARACTER OF MATERIALS

3.1 REGIONAL GEOLOGY

Palm Beach County is made up of three physiographic areas: The Atlantic Coastal Ridge, the sandy flatlands and the Everglades. The formations exposed at the surface include sand, coquina and limestone deposited during the glacial epochs starting 1 to 2 million years ago.

With the exception of the Everglades and the Loxahatchee Marsh area, where organic soils cover the surface, a layer of surface sand (Pamlico sand) overlies all of Palm Beach County. On the sandy flatlands between the Everglades and the coastal ridge, this sand is one to two feet thick, increasing to 10 feet or more along the ridge and adjacent barrier islands.

The Anastasia Formation immediately underlies the surficial sands. This formation is composed of sand, coquina, sandstone, limestone and shell beds. The Anastasia Formation underlies all of eastern Palm Beach County from the beaches, where it ranges from 40 to 50 feet thick, to the edge of the Everglades, where it can be up to 200 feet thick.

3.2 THE LOCAL GEOLOGY

The barrier islands in the project vicinity are underlain by the Anastasia Formation. Consisting chiefly of shell and marl, the Anastasia Formation has been irregularly hardened into limestone.

Pamlico sand is primarily quartz sand deposited during a higher stand of sea level and lies unconformably over the Anastasia Formation. This sand is overlain by recent deposits due to the erosion of outcroppings of the Anastasia Formation. This provides a source of shell and sand to the beach system, which itself is composed primarily of silica sand and shell.

3.3 MATERIALS ENCOUNTERED

The construction effort for this project will occur at two different locations: Peanut Island and Bonefish Cove, as shown in Plate 1. Peanut Island contains two dredged material management areas (DMMAs), a recreational area, and a historic bunker, as shown in Plate 2. One DMMA is owned by the Florida Inland Navigation District (FIND) and the other DMMA is owned by the Port of Palm Beach.

The materials encountered were summarized from the non-federal project sponsor’s borings.

The geotechnical data representative of the materials encountered were supplied by the non-federal project sponsor and may not conform to Corps of Engineers standards. Prospective offerors are cautioned to use great care in the evaluation of these borings.

3.3.1 Peanut Island

The materials encountered within the FIND and Port’s DMMAs on Peanut Island were dredged from maintenance dredging within Lake Worth Lagoon and the adjacent inlet, and primarily consists of poorly graded, fine- to medium-grained sand. The sand has trace to some silt, organic material (including plant debris, roots, and peat), whole and broken shell fragments ranging from sand to gravel size, and gravel to boulder size rock fragments.

Various large and small debris such as ropes, anchors, aluminum cans, and plastic bottles from navigation activities from prior maintenance dredging events may be encountered within the DMMAs. Some larger construction debris, such as concrete, concrete with rebar, PVC pipes, and other associated debris may also be encountered within the DMMAs.

The Port’s DMMA has an uneven topography and is overgrown with grass, shrubs, bushes, and small trees. The FIND DMMA has a more even topography and is mostly barren, with the exception of some weeds and grasses.

3.3.2 Bonefish Cove

The materials encountered within Bonefish Cove primarily consist of poorly graded, fine to medium grained sand, sandy silt, silty sand, supersaturated silt, and limestone.

5.3 BORING LOG NOTES

Borings B01 and B02 were driven using the Standard Penetration Test (SPT) procedure with a 140 pound hammer with a 30-inch drop using a split spoon (1 3/8-inch I.D. and 2-inch O.D.) in accordance with ASTM D 1586. Borings were advanced in 18-inch intervals, or until refusal was encountered. Refusal is defined as a total of 50 blows of the hammer within any 6-inch increment, a total of 100 blows within any 1-foot increment, or no observed advance of the sampler after 10 successive blows of the hammer. When refusal was encountered, the borings were continued with a 4-inch by 5 1/2-inch diameter core barrel until the rate of penetration indicated softer material, at which point the SPT procedure was resumed.

Borings CB-LWL-1901 to CB-LWL-1914 were sampled with a hand auger.

5.4 INSPECTION OF RECOVERED MATERIALS

The material recovered from borings is not available for inspection. The borings were collected by the non-federal sponsor and are not in the possession of the Government.
