I would check with the city and talk to the project engineer. Every city has construction standards they are supposed to follow when designing or constructing a new road project. Alot of cities use State department of transportation specifications so you could check into that. If your drive doesn;t meet those slope standards there should have been a design exception and in which case they at the very least they should have talked to your parents about the change. My guess is that someone screwed up designing the new road grade and didn;t match it to the new sidewalk grade correctly or there could have been a staking error and they failed to correct it properly and just "made it work". There are alot of possibilities as to why it didn't turn out like it was before, even moving the sidewalk closer to the road could have effected it. I would go talk to the city and find out who the project engineer is and talk to him about it. That would be the best place to start. Hope this helps you out a bit.
