Ecoroof seminars and incentives

The city has scheduled two one-day seminars; one for professionals on Tuesday, December 6, and one for property owners on Saturday, December 10. Register and get more information at

The city is also accepting applications for ecoroof incentives to spur ecoroof construction in Portland. The deadline to apply for this cycle is Thursday, December 1, 2011. The next ecoroof incentive cycle will begin in spring 2012. The city will accept incentive applications twice a year through 2013.

The incentive pays up to $5 per square foot for new ecoroof projects in the city. Ecoroofs in Portland typically cost between $5 and $20 per square foot. Industrial, residential, commercial and mixed-use projects are eligible. For this cycle, the city added criteria to promote diversity in ecoroof projects. Projects that apply the new criteria will rate higher during the evaluation process.

Go to, email or call 503-823-7914 for application information.
