You might propose to use the art grant money to host a sculpture and/or natural sculpture contest in a public space, or in partnership with a local business (or businesses). The sculpture or art can be donated to the space where the contest is held.
This is a nice way to build community, get exposure for local arts and artists, and to beautify a neighborhood.
Your best bet when applying for a grant of this type is to find a way to tie the cultural event into the community in which you live. Many of the grant committees want to see that the money is being used to develop or improve the cultural awareness of art within the community. This could be arranging a poetry reading, creating a writing group, bringing a repertoire company into the community--anything that enriches your local community would be a good idea.
