The manual muck probes performed about every 1,000 feet along the alignment revealed a
maximum surficial muck thickness of approximately 3 feet. See individual muck probe results
on Figures 2A through 2S in the Appendix.
The boring results are presented on the Roadway Auger Boring Results sheets (Figures 4 through 6)
in the Appendix.
5.3 Stormwater Pond Options Boring Results
In general, the pond borings performed typically encountered fine sand to fine sand with silt
(Stratum 1, A-3) to typical boring termination depths of 4.5 to 6 feet below the existing ground
surface.
One notable exception to this general profile is the surficial layer of mucky fine sand (A-8)
encountered from ground surface to a depth of 1 foot at boring location PB-2 (Pond 1B).
The boring results are presented on the Pond Boring Results sheet (Figure 7) in the Appendix.
5.4 Groundwater Levels
The groundwater levels at the boring locations were measured approximately 24 hours after the
borings were performed. Groundwater levels were encountered in the roadway auger borings at
depths ranging from 0 to 5.0 feet below the existing ground surface. Groundwater was
encountered in the pond borings at depths ranging from 1.1 to 4.7 feet below the existing ground
surface, corresponding to approximate elevations of +61.0 to +66.3 feet NAVD88.

TABLE 5.5
REQUIRED MINIMUM THICKNESS FOR NEW CONSTRUCTION OR RECONSTRUCTION
In order to avoid the possibility of producing an impractical design, the following minimum thicknesses are required for New Construction. It is assumed that a 12-in stabilized subgrade (LBR 40) is to be constructed in order to establish a satisfactory working platform.

FC-12.5 and FC-9.5 can be considered as structural courses and are sufficient for single layer shoulder pavement.
FC-5 has no structural value and is always shown as 3/4-in thick.
See Chapter 8 for Shoulder Design Guidance.
