In October 2023, Bloomberg Philanthropies selected Phoenix as one of eight winners of its Public Art Challenge. This unique grant program, launched in 2014, awards $1 million to support temporary public art projects that address important civic issues in cities nationwide and showcases the potential of artists to act as civic leaders. Phoenix's project, ¡Sombra! Experiments in Shade has commissioned nine artists to create shading and cooling installations in response to extreme urban heat. From April – September 2025, the installations will be temporarily located in neighborhood parks throughout Phoenix.
