@carraway sewers can create holes on their own, especially with water leaks.

In the case above, the NY city kept fixing the pavement without bothering to look into why it kept sinking. The sewer system had a break and was creating a void. Eventually the void created enough pressure on the surrounding pipes a gas line cracked. Migrated to a building.and killed 8 people.
Make safe includes stopping people or cars fom falling in or getting in harms way. It doesn't mean fixing. That they have widened the area without fixing is concerning.
I am surprised this hasn't been fixed yet.
