Portland’s New Ecoroof Requirement: New Design and Maintenance Strategies

As of July 9, 2018 Portland’s new Central City zoning code will require all new buildings of 20,000 sf or more to install ecoroofs. After 22 years, since the first ecoroof was installed on a Portland residential garage, the city has enacted one of the most comprehensive Ecoroof (Greenroof) mandates in the United States. This was no easy decision, yet after many years and the construction of more than 600 ecoroofs the city had the experience and confidence to pursue such a requirement. Tom Liptan, FASLA, Green Infrastructure Consultant and former Portland Ecoroof Program Technical Manager will discuss ecoroofs in detail beginning with a look at some of Portland’s first ecoroofs and concluding with a discussion on innovative ecoroof strategies.

The presentation will highlight the following topics:
· Portland’s first ecoroofs installed in late 1990s and early 2000s and the most pertinent lessons
· Development of the industry through to today, with attention to pertinent successes and bumps in the road related to architecture and ecoroof design
· New ecoroof techniques for design and O&M that are proving cost effective and durable, especially as these techniques apply to the city’s new ecoroof requirement
· Emerging and innovative green infrastructure techniques
