Property owners can get back much of their cost
The city of Portland is reopening the spigot of subsidies for residents and commercial property owners interested in adding a new ecoroof to their homes and buildings.
Ecoroofs are vegetated roof systems that reduce stormwater runoff, improve air quality and save energy.
The city pays up to $5 per square foot for new ecoroof projects, which typically cost between $5 and $20 per square foot. Industrial, residential, commercial and mixed-use projects are eligible. Deadline to apply for this round is Dec. 1, 2011. The next ecoroof incentive cycle will begin in spring 2012.
Since the program began, the city has approved $2.4-million for 145 projects, resulting in 11 acres of new ecoroof. There are currently 300 ecoroofs in Portland covering nearly 15 acres.
The program is part of the Grey to Green effort to expand Portland's green stormwater management infrastructure, protect natural areas and improve fish and wildlife habitat. The Grey to Green goal is to add 43 acres of new ecoroofs by 2013.
