Temporary installations have their own program context
Phoenix’s public-art plan describes temporary commissions for artists across disciplines at selected public sites, with work viewable for a limited period. This sits alongside permanent commissions and collection purchases, each of which has a different intended life. The temporary category can support a proposal based on a defined public encounter rather than permanent ownership, but the plan does not establish a particular open call, display duration or funding amount for an individual artist.
