2 PROJECT BACKGROUND

Herbert Hoover Dike (HHD) is an earthen embankment that completely encompasses Lake Okeechobee and is located in south central Florida. To reduce seepage pathways, restoration of the embankment is being achieved by constructing a new culvert with a cutoff wall and an impermeable core. The location of the project site is shown on Plate 1.

Total replacement of S-288 (also known as Culvert HP-1) and construction of an impermeable core will take place within the construction limits. This geotechnical data report presents all the lateral geologic information for this site, and will not be limited to the construction limits.

3 CHARACTER OF MATERIALS

3.1 REGIONAL GEOLOGY

The S-288 project site at HHD is located on the northern boundary of Glades County on the upper northwestern shore of Lake Okeechobee in the Okeechobee Plain physiographic region. The regional geology of Glades County for the Quaternary and upper Tertiary Systems range in age from Recent to Pleistocene to Miocene Age sediments. The Recent to late Pleistocene Age sediments are undifferentiated and cover the county with a range of 2 to 100 feet in thickness of fine to medium quartz sand, shells and organic soils. From the Atlantic Coast towards Lake Okeechobee, the sand sediments thicken, and thin organic rich soils appear. Below the sands and organic soils, the mid to early Pleistocene’s Anastasia Formation is present. The Anastasia differs in composition from a coquina to pure sand, but in Glades County, it is composed of semi-consolidated fine quartz and carbonate sands, and shell beds. The Anastasia ranges in thickness from 200 feet at the coast to 20 feet at Lake Okeechobee, where it then pinches out or merges with the Ft. Thompson Formation. The composition of the Ft. Thompson Formation varies throughout Glades County but is primarily composed of marine sands, shell beds, limestone, or sandstone which are all present at the project site. The formation ranges in thickness from 2 to 15

00 31 32 - 2 feet. These deposits lie unconformably on the upper Miocene/Pliocene sediments of the Caloosahatchee and Tamiami Formations. The Caloosahatchee and Tamiami sediments are comprised of shelly quartz sand, silty shelly sand, and indurated clayey sand with occasional thin interbedded limestone and sandstone. These sediments vary in thickness (10-140 feet) throughout the region, and generally thin towards the west.

The Hawthorn Group sediments of middle Miocene Age, lies unconformably below the upper Miocene/Pliocene sediments which underlie all of Glades County. The Hawthorn Group is composed of dark green to white phosphatic clay containing silt and quartz sands, interbedded with layers of sandy limestone and chert. Its formational contact ranges from 80 to 200 feet below land surface near the lake and dips to 400 feet near the coast. The thickness of the Hawthorn Group ranges from 250 to 750 feet.

3.2 MATERIALS ENCOUNTERED

3.2.1 Structures 288 Embankment Fill

The materials encountered for S-288 (Culvert HP-1) are represented through the 10 borings, 2 test pits, and 18 probes plotted on Plates 2 and 3. The initial materials encountered in the borings drilled on land is embankment fill. This fill material had been hydraulically or mechanically placed during the initial construction of the embankment at S-288. When the embankment was raised and widened, new material were mechanically placed. The thickness of the fill averages 20 feet at the crest and thins on the flanks at both structures. The embankment material is generally a heterogeneous mixture of loose (lightly compacted) to dense fine to medium quartz sand with varying amounts of shell, silt and organics. Other materials encountered are limestone and sandstone gravel, cobbles and occasional boulders (+6”) that have varying minor percentages and distribution within this embankments. Fill is expected to run deeper at the structure location due to the initial culvert construction excavation. Debris from past construction activities are also expected to be buried within the embankment. The debris can be of any size andlength and can be composed of the following materials: metallic, wooden, masonry, trash, etc.

3.2.2 Structure 288 Foundation Materials

The top of natural ground attains an average elevation of 12.7 feet (NAVD-88). The materials consist primarily of organic stained silty-sand. The sand is composed quartz with occasional pockets of peat or organic silt. These materials have varying amounts of silt and are best delineated by their dark gray to dark brown color. This dark layer averages over 1.5 feet thick, but in the original footprint of the culvert excavation may have been removed.

A highly weathered, discontinuous, light gray limestone layer is encountered at an average elevation of 8.3 feet. The limestone was sandy, fossiliferous, interbedded with poorly cemented silty/clayey sand and shell. The hardness of the limestone ranged from soft to moderately hard.

The limestone layer averages 2.3 feet in thickness where encountered.

Below the limestone layer few thin layers of limestone are encountered within the sediments below the primary limestone rock layer. These sediments consist of a semi-homogeneous light greenish gray to gray, fine, loose to dense quartz sands. These sands contained mostly to trace of shell, and are best characterized by its intra-bedding of discontinuous layers of clayey-sands and high plasticity clays that range from 1-inch to 5.0 feet thick. These discontinuous layers are found at average elevations 15 to -65 feet.

At an approximate elevation of -8 feet, a fat, high plasticity, soft, organic clay is encountered. The fat clay is very dark brown to grayish brown contains little silt, little sand, and a trace of organic matter and is sometimes interbedded with clayey sand. The average thickness of this layer is 2.5 feet but is not present in all borings.

Slug tests for determination of hydraulic conductivity were obtained from temporary wells installed in 2017 at companion borings HHD17-S288-CB-1 (HHD13-S288-CB-2), HHD17-S288-CB-2 (HHD13-S288-CB-5), and HHD17-S288-CB-3 (HHD13-S288-CB-7). Slug tests were also performed in temporary wells installed in 2016 at boring locations HHD13-S288-CB-2 and HHD13- S288-CB-5. No borings logs for the 2016 were created for the 2016 slug testing wells. Three rounds of slug testing were performed in each well with each round consisting of a failing and rising head measurements. See Table 4 for test results.

5.3 BORING LOG NOTES

All borings were driven using the Standard Penetration Test (SPT) procedure with a 140 pound hammer with a 30-inch drop using a 2.0 foot split spoon (1 3/8-inch I.D. and 2-inch O.D.). 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. No rock core drilling was performed during this investigation.

Field investigations at Structure 288 were performed in 2013, 2016 and 2017. Some blow counts for the 2016 field investigation were lower than those in the 2013 field investigation in identical material at identical depths. These lower blow counts are attributed to heaving sands within the hollow stem augers.

Test pits were excavated using a CX130C Excavator with a 24 inch wide bucket. Soil was excavated in 3 foot lifts. The maximum excavation depth was 10 feet below ground surface.

Instability of the test pit due to ground water forced early termination of some excavations.

Sediment probes were accomplished using a one-inch hollow aluminum pipe 32’ long with an attached 1’ X 1’ X ¼” plate on one end. The plate end of the probe was lowered to the bottom of the channel where the top of sediment is measured from the lake surface. The one-inch end of the probe was then pressed into the sediment to refusal. The thickness of the sediment is obtained by the final pushing.

5.4 INSPECTION OF RECOVERED MATERIALS
