Sidewalk Buckled? Should City Pay?

The tree is the city's tree. The sidewalk is the city's sidewalk. When the city tree pushes the city sidewalk up, shouldn't the city pay to have it fixed?

We recently received a notice in the mail that we are obligated to fix each square of sidewalk at about $250.00 PER square.

We also have to hire a contractor to do it and can't do it ourselves. We have 4 squares to 'fix' and that's over $1,000.00 out of our pocket.

What are your thoughts? Should the city pay? Or do I have to cough up more 'taxes'? Just wondering. - Alan
