Work Order No. XX 8"' Street Roadway Improvements — 66" Avenue to 82nd Avenue The field program will include conducting three (3) Standard Penetration Test (SPT) borings to 25 feet (pond site) and five (5) auger borings to 10 feet at accessible locations to our truck -mounted drill rig. We will also conduct 45 hand auger borings to 6 feet at the vicinity of the locations provided by the engineer. The SPT borings will be drilled using a procedure similar to the Standard Penetration Test outlined in ASTM D-1586 and will be sampled at 18 -inch or 24 -inch intervals to 10 feet deep and at 5 -foot intervals below 10 feet. The auger borings will be drilled to a depth of 10 feet below existing ground surface at the requested locations and will be performed using a 4 -inch diameter, truck mounted continuous -flight auger. The hand auger borings will be performed using a 3 -inch diameter, hand-held bucket auger. Each sample will be removed from the sampler or auger in the field and then examined and visually classified by crew chief. Representative portions will be sealed and packaged for transportation to our laboratory for further analysis as required. Water level observations will be made in the boreholes during the drilling operation. We will also perform a series of muck probes within the existing canal on the north and south sides of the 8th Street between 66th Avenue and 82nd Avenue that may be incorporated in the proposed roadway improvements. The muck probes will be performed by pushing a steel rod into the ground and measuring the approximate thicknesses of accumulated soft sediment at the bottom and sides of the canals. We will also install six (6) piezometer wells by inserting slotted 2 -inch diameter PVC well casings within the completed boreholes and backfilling the annulus with soil cuttings. Each well would be installed using a 3 -inch diameter, hand-held bucket auger to a maximum depth of 10 feet below existing ground surface. The locations for the piezometer wells will be selected by the client. Also, the piezometers standing above the existing ground surface will be painted orange or red. The groundwater level will be measured and recorded within the piezometers once per week for a period of 90 days. We recommend that the project surveyor locate our boring/well locations horizontally and vertically (i.e., determine the elevation of the ground surface at the boring locations). This information will increase the accuracy of the data obtained. In addition, six South Florida Water Management District (SFWMD) exfiltration tests will be performed to obtain soil hydraulic conductivity values for others to use in the design of stormwater facilities. The exfiltration test will be performed in accordance with the methods described in the SFWMD Permit Information Manual, Volume IV. Page 3 of 9
