2 PROJECT BACKGROUND

Herbert Hoover Dike (HHD) is an earthen embankment that completely encompasses Lake Okeechobee, located in South Central Florida. Stilling wells at pump station S-4 and structure S- 131 are being replaced. No new geotechnical investigations were compiled for this contract and only historical geotechnical data were used to provide materials encountered presented in this report. Plates 1 through 5 provide the site layouts and the geotechnical data points within each of the project areas

3 CHARACTER OF MATERIALS

3.1 REGIONAL GEOLOGY

Pump Station S-4 is located in Reach 2 of Herbert Hoover Dike which is located in the Northwest corner of Hendry and the southeast corner of Glades Counties in the Everglades physiographic region. The regional geology of both Hendry and Glades counties for the Quaternary and upper Tertiary systems range in age from recent to Miocene Age sediments. The recent to late Pleistocene age sediments are undifferentiated and cover the counties with an average 5-foot-thick layer of siliciclastic and organics. From the west and northwest moving towards the lake to the Everglades area, the sediments are terraces of fine to medium quartz sands and shell. Closer to the lake in the Everglades area, the sand pinches out and rich organic soils and peat are found, with thicknesses ranging from 2 to 8 feet. Below the sands and peat, the Pleistocene age Ft. Thompson Formation is present, which is included within the Tertiary-Quaternary shell units group (TQSu), as mapped by the Florida Geological Survey. The Ft. Thompson is prevalent in the Everglades and its composition varies throughout but is primarily composed of alternating fresh water and marine sands, shell beds, limestone, or sandstone. The formation ranges in thickness from 2 to 25 feet.

Structure 131 (Lock) (S-131) is located in Reach 6 of Herbert Hoover Dike in the vicinity of Lakeport which is located in Eastern Glades County bordering the northwestern shore of Lake Okeechobee in the Sandy Flatlands 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.

HHD S-4 S-131

SECTION 00 31 32 Page 4

The recent age sediments are localized and consist of: sand, peat, and alluviuvial deposits. These sediments occur at land surface to a maximum depth of 20 feet below land surface in the Kissimmee River flood plain and are underlain by Pleistocene age undifferentiated deposits, described as fine to medium grained quartz sand with clay and some shell. Where recent sediments are not present, the undifferentiated deposits can extend from land surface to an approximate depth of 50 feet below land surface.

3.2 MATERIALS ENCOUNTERED

3.2.1 Pump Station S-4

Borings HHD17-S4-CB-1 and 2 are located at PS-4. The borings indicate that the embankment fill is approximately 40 feet thick to a base of the structure at approximate elevation -6 feet. The fill consists of a homogeneous, light brown, loose to medium dense, slightly silty fine quartz sand, with traces of shell and limestone gravel. The foundation materials are comprised of clean to slightly silty fine-grained quartz sand, with shell to an average elevation of -27 feet. The shell content can range from 20% to 45% sand to gravel-sized, whole and broken shell. The sand unit is generally loose to medium dense evidenced by SPT N-values ranging from the single digits to the teens. Sandstone is encountered underneath the sand unit to the terminal depth of the borings at -33 feet. The sandstone layer is gray, sparsely fossiliferous, moderately hard, weathered, and medium to thick bedded. The sandstone was sampled with SPT, the N-values averaged in the 20’s. The closest UCS test in this unit was found in boring HHD10-R2-CB-15C with a strength of 75.6 PSI.

3.2.2 Structure 131 (Lock)

The embankment fill is of variable thickness around these structures, dependent upon the depth of excavation for each structure feature. Fill may be found as deep as approximate elevations 0.0 feet for the lock and -5.0 feet for the pump station. Boring HHD17-S131-CB-1, the base of fill was encountered above elevation 10.0 feet, which is not near the deepest structure excavation. However, the density of the materials are slightly higher which range from loose to medium with SPT N values that range from the single digits up to the 40’s. The foundation materials from the top of natural ground at approximate elevation 11.0 feet are comprised of fine quartz sand, silty sand, and clayey sand with shell and occasional thin layers of moderately hard sandstone. This sand layer is found to be approximately 11 feet thick and has densities that range from loose to medium with an occasional layer that is dense. At approximate elevation 0.0 feet, a dominant sandy silt/clay layer with occasional clayey sand layers is encountered and extends beyond the bottom depth of the borings, to elevation -14 feet. The material is greenish gray, soft to medium stiff consistency, variable plasticity, with variable sand and shell content.

3.2.3 Local Ground Water

No Ground Water study was completed for S-4 or S-131, however, based on historical information ground water lies within a few feet of the ground surface along the flanks of the embankment.

Ground water levels are very dynamic, and responsive to changes in the level of the lake. Changes in lake levels, recent rain events and agricultural pumping can induce sudden changes in the local ground water levels. Typically, toe ditch water levels are generally indicative of the local ground water levels. Water levels noted on the boring logs shall not be taken as the current water levels.

5.4 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.

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.

Cone Penetrometers were advanced using a truck mounted penetrometer system. The truck has a static weight of 22 tons and pushes a 10 cm2 base cone at a rate of 120 cm/s. Testing procedures follow ASTM D5778-87. For testing results, see paragraph 5.6.

5.5 INSPECTION OF RECOVERED MATERIALS

The material recovered from borings marked with a checkmark in Table 1 and Table 2 is available for inspection by prospective offerors at the Corps of Engineers District warehouse in Jacksonville, Florida.

Address: 3077 Talleyrand Avenue Jacksonville, 32206 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

5.6 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.
