Three of Portland’s public art projects were among 31 projects to be nationally recognized this week, winning awards from Americans for the Arts. A Division Street project called This All Happened More Or Less, by Crystal Schenk and Shelby Davis, Westmoreland Park Nature Play in which artist Adam Kuby worked with Greenworks Landscape Architects to design a nature-based children’s playground, and the Rippling Wall at Fire Station 21, by David Franklin, were the three local projects to be honored.
