1.2 PROJECT BACKGROUND

Herbert Hoover Dike (HHD) is an earthen embankment that completely encompasses Lake Okeechobee, located in south central Florida. To reduce seepage pathways, restoration of the embankment is being achieved by constructing a seepage cutoff wall into its foundation and replacing or abandoning aged culvert structures.

Culverts 7, 9, and Taylor Creek were abandoned in 1991 by capping both ends of the culvert barrels with concrete, backfilling the barrels with sand, and filling in the inverts with fill material to match the existing grade. To reduce risk, a cutoff wall will be placed through the crest of the embankment, through the culvert and into the foundation completely sealing it off.

1.3 CHARACTER OF MATERIALS

1.3.1 Regional Geology

Reach 5 of Herbert Hoover Dike is located on the southern boundary of Okeechobee County on the northern most shore of Lake Okeechobee in the Okeechobee Plain physiographic region. The regional geology of Okeechobee 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 foot in thickness of fine to medium quartz sand, shells and organic soils. From the coast to Lake Okeechobee, the sand sediments thicken, and thin organic rich soils appear below. Below the sands and organic soils, the mid to early Pleistocene Anastasia Formation is present. The Anastasia differs in composition as a whole from a coquina to pure sand, but in Okeechobee county, it is composed of semi-consolidated fine quartz and carbonate sands, shell beds, and thin discontinuous layers of sandy limestone or sandstone. 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 Ft. Thompson is prevalent in Okeechobee County and its composition varies throughout, but is primarily composed of marine sands, shell beds, limestone, or sandstone. The formation ranges in thickness from 50 to 20 feet. These deposits lie unconformably with 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 have an overall trend to thin to the west.

The Hawthorn Group sediments of middle Miocene Age, lies unconformably below the upper Miocene/Pliocene sediments, which underlie all of Okeechobee 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.

1.3.2 Materials Encountered

1.3.2.1 Embankment Fill

The materials encountered for Culverts 7, 9, and Taylor Creek are represented through the borings plotted on Plates 2 through 4. The initial materials encountered in the borings drilled on the land are embankment fill; this fill material was placed hydraulically during the initial construction. Later, when the dike was raised and widened, the materials were mechanically placed. The thickness of the fill averages 30 feet at the crest and thins on the flanks. The embankment material is generally a heterogeneous mixture of loose (lightly compacted) to dense, fine to medium grained quartz, silty sands with shells, and minor percentages of organic soils. Other materials encountered in the fill at minor percentages are limestone and sandstone gravel, cobbles, and occasional boulders (+12”) that have varying percentages and distribution within the embankment. Fill is expected to run deeper and extend further out at this location due to the original culvert construction.

The abandoned in-place steel barrels have been backfilled with a loose, clean, fine to medium grained quartz sand. Borings HHD11-C7-CB-4, HHD11-C9-CB-4, and HHD11-TCC-CB-4 were drilled to intersect a barrel.

The backfilled inlet and outlet of the culvert may have buried riprap along its original construction template.

1.3.2.2 Culvert 7

The top of natural ground typically consists of sandy organic soils that would be expected to be encountered at an estimated elevation of 12 feet NAVD88. At this location, organic soils were not encountered, but still may exist even where there is no indication of them seen on the boring logs.

At Culvert 7, the top of natural ground to the terminal depth of the borings (elevation of -86) is a unit of semi-homogeneous fine, light greenish gray, silty to slightly silty quartz sand with shell. The shell content varies horizontally and vertically, containing from 5 to 45% sand to gravel sized whole and broken shell. At various locations, within this sand unit, the sand is composed of wholly fine to coarse sand sized broken shell with lesser amounts of quartz sand and fines.

The upper part of this sand unit has trace to few silt to an elevation of -35 feet, the silt and traces of clay increase with depth. This sand unit is generally of loose to medium dense consistency with SPT blow counts ranging from single digits into the 30’s. Higher blow count zones are present and are generally caused by zones with a higher degree of cementation, consolidation or thin layers of sandstone. Multiple thin layers of soft to moderately hard sandstone can be found scattered throughout this sand unit.

1.3.2.3 Culvert 9

The top of natural ground consists of organic sandy soils that are encountered at an average elevation of 8.5 feet NAVD88. This material consists primarily of loose organic silty/clayey sands that is best delineated by its dark brown to black color. This organic material is thin at this location, usually two feet or less. Past excavations for the culvert and outlet canal may have removed the organic soil and/or placed as fill within the excavation template.

Below the organic soil horizon to an elevation of -76 the materials primarily consist of semi-homogeneous fine, light greenish gray, silty to slightly silty quartz sand with shell. The shell content varies horizontally and vertically, containing from 5 to 45% sand to gravel sized whole and broken shell. At various locations, within this sand unit, the sand is composed of wholly fine to coarse sand sized broken shell with lesser amounts of quartz sand and fines, which can account for up to 25% of the unit. This sand unit is generally of loose to medium dense consistency with SPT blow counts ranging from single digits into the 30’s. Higher blow count zones are present and are generally caused by zones with a higher degree of cementation, consolidation or thin layers of sandstone. Multiple thin layers of soft to moderately hard sandstone can be found scattered throughout this sand unit, the most notable are two 3 foot layers found at elevations -20, and -44 feet.

Below the sand unit to the terminal depth of the borings, a lean silt unit is encountered at elevation -76. This silt is gray, soft to medium stiff in consistency, and contains minor amounts of sand and shell.

1.3.2.4 Taylor Creek

The top of natural ground consists of organic sandy soils that are encountered at an average elevation of 7.4 feet NAVD88. This material consists primarily of loose organic sands with varying amounts of silt that is best delineated by its dark brown to black color. This organic material is thin at Taylor Creek, usually three feet or less. Past excavations for the culvert and outlet canal may have removed the organic soil and/or placed it as fill within the excavation template.

Below the organic soil horizon to the terminal depth of the borings (elevation of -81) a thick unit of semi-homogeneous fine, light greenish gray, silty to clean quartz sand with shell. The shell content varies horizontally and vertically, with 5 to 45% sand to gravel sized whole and broken shell. At various locations, within this sand unit, the sand is composed of wholly fine to coarse sand sized broken shell with lesser amounts of quartz sand and fines. This sand unit is generally of loose to medium consistency with SPT blow counts ranging from single digits into the 30’s. Higher blow count zones are present and are generally caused by zones with a higher degree of cementation, consolidation or thin layers of sandstone. Multiple thin layers of soft to moderately hard sandstone can be found scattered throughout this sand unit, the most notable is a 2 foot layer found at elevation -25 feet.

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.

1.5.3 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.

1.5.4 Recovered Materials

The material recovered from all borings is available for inspection by prospective offerors at the Corps of Engineers District warehouse listed below:

Address: 3077 Talleyrand Avenue Jacksonville, 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 904-232-1607 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) the project title; (2) the specific borings or entire set which are to be viewed; (3) the date, time, and duration of the visit; the name of the person(s) and company to view the borings; and (5) a 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.

1.5.5 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.
