It's the same as those that appear in The Walking Dead game and, from what I've heard since I haven't read them, the comics. Also seen in the suburbs of the game The Last of Us. Can't seem to find it again, but the explanation I read was that the quadrants indicate: the date the building was inspected (top quadrant), number of survivors (bottom I think?), number of infected (right?), and maybe supplies available (left).

 

That is the marking for FEMA to analyze. On the left goes the branch of the military that drew it. In this case the Ca national guard. He was starting go write a C I think. On the top goes the date. On the right goes the hazard, such as contaminated water, etc. On the bottom goes the number off occupants, living and dead.

 

I noticed this as well and then realized it looks a lot like what the National Guard/FEMA used on house after Katrina in NOLA. It's the little details like this in this show that keep me on my toes and keep me interested.

 

Was just going to mention Katrina. I remember seeing those things put on houses in NOLA too.

 

fema house marking

 

Infected. Burn it down.

 

FEMA made those markings on the houses in my town after that bitch Sandy rolled through. They had different colors. I think one meant the house was cleared to enter and one was to mark a demolition.

 

I liked how hey showed the military locking down the community and marking the houses and we had the two polar opposite reactions. The more naive Travis said everything was going to be okay now, and Daniel (with experience in a crumbling society in El Salvador) saw the military's actions as the beginning of the end.
