It's hard to keep up with this thread, every time I finish a page, I'm still about a page behind. So apologies if this has been addressed between where I stopped reading and the current end. I keep seeing the "command center" issue being brought up.
I wanted to remind all of you that the Incident Command System (ICS) which is used by LE, EMS, SAR and other agencies to manage large incidents, was designed to be flexible and adaptive. It is never a surprise when a Command Center is moved, or perhaps a sub command center is implemented, which sounds like may have happened here, or when another functional area is broken off as the incident grows in scope. A staging area may also be added, at some distance from the command center, to keep the boots-on-the-ground folks from interfering with the hundred-pound-heads in Planning.
I believe that everyone can take the free online ICS classes offered by FEMA. Many of you who are involved in EMS, LE and SAR are probably already quite familiar with them, because they're required for many of us. I suspect the questions and reading-between-the-lines going on in this thread are from those who are unfamiliar with ICS, or maybe took the courses a long time ago and forgot how it works.
If you're going to read anything between the lines here, it MAY indicate an expansion. We MAY find that this is a disposal site with multiple uses, or that LE wants to rule that out. We MAY find that there is an intent to occupy this space for a week or more, and anticipating more involvement with media and other search resources, that parking became and issue and played into the decision to move the command center. It may be as simple as elevation for portable radio comms.
I've seen Command moved, expanded, and broken into functional areas on numerous search missions.
