WA state maintaining an easement Who is responsible in fixing the water run off and the slanted cement?

If citiy staff or city admininstration will not address this to your satisfaction, take this to your elected official such as your alderman. Take pictures and provide the documents to show your water damage. Do everything in writing to build a record of your situation.

You say the city sewer system damaged the driveway but you do not say how the city was responsible for the sewer becoming blocked. That will be a matter you have to convince the official about if city staff and city administration have looked into it and disagreed with your conclusion.

Show before and after photographs to prove that the driveway is not in the same configuration and level as before the water damage.

I hope these ideas help you. Good luck.
