I had some friends who moved into a new apartment. They did not rush out immediately to buy a garbage bin to put their garbage in so for a whole week it was in a garbage bag on their balcony. The neighbour called the health inspector who was duty bound to come out and have a look. The inspector hated these kind of nuisnace calls and ended up charging the neighbour because he had a barbecue on his balcony which he wasn't allowed to have.

Any small voilation that you can bring on your neighbour? A question you could ask if someone comes out to look at your property? "Is that all right, officer, I was wondering..."

Can you talk to your neighbour about it? Was she aware of the reason for all of your work about the driveway or did you assume she would understand what you were doing?
