1. No construction on the terminal groin was observed today (12/21). CDC indicated that no work will be done on
the terminal groin this week but that stone delivery to the site would continue until the quarry shuts down for
the holidays on Dec. 23rd. CDC indicated that flatbed trucks would continue to deliver Size B armor stone until
the Dec. 23rd when the quarry closes down. CDC indicated that construction on the terminal groin would resume
on Monday Dec. 27t"
2. A CDC operator was observed on site to unload armor stone being delivered. No armor stone was observed being
delivered during the site visit.
3. The On -site Observer noted two (2) rubber mats at the seaward end of the east side of the structure had been
moved off of the structure by wave action and only a corner of each of the mattresses were still touching the
structure. It appeared as though the waves had moved the stones that were holding them in place (See Photos
#7 and #8).
4. Construction signs were observed in place and fencing was observed around the 4th Street and Shallotte Blvd
staging and laydown areas.
5. No work was observed at the Shallotte Blvd staging area. Signs and barricades were observed in place.

meeting was attended by Debbie Smith (016), Justin Whiteside (016), Jim Gunn (CDC) via phone, Adam Priest
(CPE), and Brad Rosov (CPE) via phone. Discussions during the meeting informed the Town that Size A armor
stone would begin being delivered next week, starting Jan. 27t" and that CDC is expected that Phase 1 of the
construction should be close to finishing by mid -February. The meeting also discussed that the sheet pile wall
installation may begin by mid -February. Jim Gun mentioned that the sheet pile sections are in the process of
being coated which is expected to take several weeks. Justin Whiteside asked if there had been any updates from
the vibration monitoring equipment. Adam Priest stated that he had not heard any updates regarding any
vibration results. Marine Mattress construction would be ending mid -December but the Shallotte Blvd staging
