This case study centers around the ecoroof of Ecotrust's Jean Vollum Natural Capital Center.
Ecotrust is a conservation non-profit based in Portland, Oregon working to support the emergence of a conservation economy within its bioregion, the Pacific coastal temperate rainforest.
Portland's heavy rainfall combined with the city's large area of impervious surfaces has lead to higher volumes of stormwater runoff, which eventually overflows into the Willamette River. |

Ecotrust's main interest in ecoroofs is their role in stormwater management, and Ecotrust hopes the building will successfully divert 95% of its stormwater from the city's system.
Covering the second story of the Natural Capital Center are more than 5000 square feet of soil and native plants. |

Here is our brave team for this project. We enjoyed not only discussing but digging dirt on the roof of the urban building and measuring mysterious black trash bags at the central post office in Portland....
