Back in February, we wrote about the new specs for a low cost, low maintenance ecoroof , which can help make ecoroofs more affordable for some home and building owners. The Columbia Boulevard Wastewater Treatment Plant Screenhouse is one of the first ecoroofs in the city to use the red cinder design, a simple lightweight approach that reduces the need for maintenance. Here are some update photos from that ecoroof, now with the sedum in full bloom. The 5,700 ft² project was installed in 2011 and has never been irrigated.
Several of Environmental Services' facilities have ecoroofs, and this innovative design allows us to keep installation and irrigation costs low while providing all the benefits we get from ecoroofs. To learn more about ecoroofs, visit the Portland Ecoroof Program website: www.portlandoregon.gov/bes/ecoroof.
