Is my driveway covered if the city cut through it to fix fix their water leak? 
This one can get a little tricky . Usually pipes from house to street are the responsibility of the homeowner so if the city was kind enough to fix a leak on your actual property then you saved yourself a ton of money by not having to fix it yourself which is usually the responsibility of the homeowner . Since there is no damage to the dwelling there would be no coverage from your homeowners policy unless you had service line coverage on your policy . Most insurance providers do not offer this coverage . If the city was being nice they may patch the hole they dug . If the problem is off your property line then the city will have to fix or patch what the city dug out .
