Boise City WaterShed The Boise WaterShed’s messages are emulated through the captivating works of art in and around the center. In 2001, the Boise City Council and Mayor passed a landmark "Percent-for-Arts" ordinance, committing up to 1.4% of eligible municipal capital projects for public art. Through this fund, local, regional, and national artists have captured iconic and symbolic messages about our watershed.
