Eco roofs are living breathing roofs with plants and growing media that take the place of a traditional roof. These roofs are engineered with layers of material that provide support, insulation, and a place for the plants and roots to thrive.
A new cycle of eco roof incentives began Oct. 1 to promote eco roof construction in Portland. The eco roof incentive program is part of Portland’s Grey to Green effort to increase green stormwater management infrastructure, protect sensitive natural areas and improve habitat.
The city is accepting incentive applications through Wednesday, Dec. 1, and will award incentives this winter.
The incentive pays up to $5 per square foot for new eco roof projects. Eco roofs in Portland typically cost between $5 and $20 per square foot. Industrial, residential, commercial and mixed-use projects are eligible.
The eco roof incentive application packet is available by calling 503-823-7914.
Eco roofs are vegetated roof systems that reduce stormwater runoff, improve air quality and save energy.
Since the incentive program began, the Bureau of Environmental Services has approved just over $1.2-million for 95 projects, resulting in 5.6 acres of new eco roof. There are currently 257 eco roofs in Portland covering more than 12 acres. The Grey to Green goal is to add 43 acres of new eco roofs by 2013.
