south of the south project limit, and 2 .0 miles offshore for Sectors 1 & 2 and 500 feet south
of the project and 10,000 feet offshore for Sector 7. 1 ,_ r n ,
Within the permitted area, limited sections have been
delineated for dredging based on quality of the material. The COUNTY reserves the right
to alter the dredge sections or cut depths within the permitted borrow area depending on the
quality of the material observed during the dredging process.
24. 1 . 1 Borrow Material. The Specifications and Plans are based on physical data collected
by bathymetric, jet probe, and vibracore sampling methods. Vibracore sampling
locations are shown in the Plans. The characteristics of the material in the borrow
area are generally indicated by the boring logs, sediment analysis data sheets, and
grain size distribution curves provided in Appendix A. While the vibracore samples
may be representative of subsurface conditions at their respective locations and
vertical extent, local variations are to be expected and the CONTRACTOR should be
aware that it is possible for material of differing characteristics to be present in the
Borrow Area. Should any questions or discrepancies arise relative to this data, the
conditions shall be independently confirmed by the CONTRACTOR at the
CONTRACTOR' S expense. The removal and replacement of any material deemed
unsuitable for and/or inconsistent with beach fill material will be solely at the
CONTRACTOR' S expense. No dredging is permitted in excess of the specified
dredge cut depths or horizontal limits shown on the Plans.
Based on available core boring information, in general, the material found within the
borrow area consists of poorly sorted, medium-to-fine grain size sand. Based upon
core analysis information, the composite mean grain size for the Borrow Area is
TECHNICAL AND ENVIRONMENTAL SPECIFICATIONS -23
calculated to be 0.46 mm and the silt/clay content is approximately 1 .44%. The
description of the material is based on the site investigations and core borings, which
are provided in Appendix A, and describe data for cores obtained from the specified
locations. The CONTRACTOR is solely responsible for any interpretation or
conclusions based on these data. The CONTRACTOR may view the core samples at
the Tracking Station Beach Park, located at 800 46`h Place, off North AIA, Vero
