Hi Katrina,

Your question is somewhat broad as it depends on what aspect of the damage you want to address. Is it a beloved artwork that is damaged beyond repair? Was it accidental damage that you need the community to be patient regarding the timeline for repair? Etc.

One of the best responses that I've ever seen is our esteemed colleague Susan Pontious and team in San Francisco. Following a series of news articles on the poor state of the maintenance of the hundreds of sculptures in San Francisco, this was used to negotiate for additional support for collection management and maintenance. They are now a model program for both creating and maintaining of a public art collection. 

I'm sure you'd appreciate something more specific so you may want to add a bit more context.
