Portland is changing the Nature of its rooftops with a green roof mandate!

Green roof advocates everywhere are celebrating the recently adopted Portland Central City 2035 Plan (CC2035), which includes a mandate for vegetated roofing. The Ecoroof Requirement, as it is called, goes into effect starting July 2018 and includes buildings in the Central City over net 20,000 square feet, with rooftop parking exempt. The green roof must cover 100% of the roof (that includes appropriate vegetated free zones), with up to 40% exemptions for rooftop mechanical equipment.

The success of this landmark mandate is due to a united effort between local nonprofits, community members, and our elected officials. The Green Roof info Think-tank (GRiT) has been supporting the City of Portland with green roof studies, symposia and stakeholder testimony throughout the years leading to the development of the requirement. Green Roofs for Healthy Cities, Greenroofs.com, the Audubon Society, Portland State University, and various local stakeholders have also had a significant impact on the awareness and research of green roofing in Portland and beyond.
