Because the city was demolishing the housing development to build a freeway.
We remember, the construction workers were actually for the government. They wanted to pretend they were building a freeway in the neighborhood, but they were really looking for the spaceship believing it to be in that neighborhood. The neighborhood was saved after Echo leaves on his spaceship.
shareThis will contain spoilers, obviously.
The government had found the signal for the spaceship (they had better equipment for signal detection and didn't have to wait for Echo to send out his own signals) and probably could determine the spaceship's size. When they detected Echo coming to Earth they shot him down. Pieces fell away, ended up moved elsewhere, with the main pod being where the kids found it. The government knew they needed to dig up the spaceship which was under a lot of homes. Also, if Echo got to the ship they feared it would destroy the town as it would have to rise up from under their homes. This was explained when the kids were talking to "construction worker" and why he said that Echo getting to his ship would "destroy them all". Because they needed to dig up the ship or at least get everyone away in case they failed - they invented the story of a freeway to make everyone move.
It turns out they were wrong because they didn't know Echo could disassemble the ship into small pieces to rise harmlessly from the ground and reassemble above the town safely.
