Garage Door & Curb Cutting for Removal

This evening I went to the house to see if any work was done today. I saw some long thin cardboard boxes in the garage that weren't there before. I walked through the house but could find no sign of any work.

As I started to leave, I looked up and noticed the garage door.

I stood looking at the house for a while when I noticed a lot of dried mud in the street next to our curb. I couldn't understand what it was. 

Then I started noticing the saw marks in the curb. I backed up to get a wide view. I soon realized what I was seeing. They have cut the curb into 4 segments (highlighted below) so that it will be easier to remove either by bulldozer or by jackhammer.
