It is the purpose of this Chapter and the policy of the City to promote and acquire public art and to dedicate two percent of the total eligible costs or two percent of the total eligible funds of all improvement projects (whichever is less) to public art. Public art contributes to experiences that enrich the social, physical and cultural environment of Portland and promotes dialogue among people of all ages and backgrounds. This Chapter will be implemented in a manner that benefits all Portlanders, including historically underserved communities and neighborhoods.
