Eco-Roof - Multnomah County Central Library, Portland, Oregon
A high point of my Portland foray: Touring the Central Library's new Eco-Roof with John Cabrera, Facilities Supervisor. Photos Copyright © Alice Joyce
Completed in September, 2008, the structure utilizes 24" x 24" pallets, which added to the ease of installation. The 4" deep soil blends organic and inorganic materials, mixed with Zebra, a water-retentive product made from natural cornstarch.

The roof features some 17,000 plants; drought-tolerant sedums and grasses that create a wildlife habitat, and reduce air pollution. An eco-roof is believed to filter the air, actually removing airborne particles, as it absorbs carbon dioxide.
A look at the photos reveals the roof's aesthetic element: A rich textural carpet knit of an abstract pattern that changes with the seasons.
The summer scene pictured: One of peachy pink tones melded with brick red and mahogany hues alongside pale blue-grey & shades of green, with yellow blooms and feathery inflorescences!
