County unveils library’s eco-roof

Having survived criticism from opponents of Multnomah County’s eco-roofs program, Commissioner Maria Rojo de Steffey unveiled the county’s latest sustainability-friendly roof at the county’s main library branch.

The $180,000 eco-roof, a structure that uses plants to help clean the air and absorb rainwater, marks the first such library project in Oregon. Three of the county’s 100 buildings now sport the roofs.
