Knocked over part of neighbor’s rotten decorative fence

We currently rent. There’s a small wooden decorative fence between our driveway and the neighbor’s. It is on their property line.

During a recent record snowstorm, a post of the fence was knocked over due to the snow being pushed around in our driveway by our plow. A section of it is now fallen.

The fence has had sections fall before, and parts of it were already held up by metal stakes and wire. It’s ancient and rotted through.

Our neighbor is saying using her insurance would cost her the deductible, which we would have to pay her. $2500.

She won’t let us try to fix it. (Just needs a new post and to be put back together).

Her other option is to give her $500 cash.

We do not have renter’s insurance. (I know, I know)

Are these offers outlandish for a section of a rotten decorative fence that was already fallen before?
