Rockingham Vulcan quarry. All stones appeared to be within the size range for the Size A stone (See Photo #2).
3. Construction signs were observed in place and fencing was observed around the 4th Street and Shallotte Blvd
staging and laydown areas.
4. Stone fragments were observed in a pile adjacent to the stockpile of acceptable armor stones (See Photo #3).
5. One armor stone was observed outside of the footprint of the terminal groin on the east side of the structure at
—Sta. 5+50. (See Photo #4).
6. A fragment of an armor stone was observed outside of the footprint of the terminal groin on the west side of the
structure a —6+00. (See Photo #5).
7. Depressions in the sand adjacent to the west side of the structure at —Sta. 4+00 were observed. These depressions
were caused by excavating material to form a ramp to the structure for the offroad trucks. (See Photo #6).
Items Discussed with Contractor's Superintendent, Surveyor, Regulatory Agencies, ... etc.:
1. Richard Mattingly (CDC) anticipated that 20 marine mattresses would be placed today. He also stated that the
