Here, the gov gives time windows for utility owners to dig and do maintenance, after which it'll be repaved. If you want to do maintenance on your infra, you request a timeslot and the gov groups the maintenance (eg sewer and gas). You best not miss your window.
Sure, but what happens if you have maintenance issues that arise after the window closes?
Are we really going to tell people that they can't live without sewer / clean water / electricity / whatever because the window closed 2 months ago and their problem didn't start until today?
