Metro Headquarters Ecoroof

Portland, Oregon

Filed In: , , ,

Lando and Associates worked closely with Metro Regional Government to design the planting substrate system, irrigation regime, and plant communities for a retrofitted ecoroof on their regional headquarters building.  The Metro headquarters green roof is a demonstration project for the City of Portland, sponsored in part by the Bureau of Environmental Services, as well as Metro.

The building’s ecoroof design is a model which adjacent roof areas can be retrofitted following re-roofing.  It is a retrofitting example for similar buildings attempting to meet The City of Portland’s stormwater standards.

The ecoroof design is a simple, low cost solution for stormwater management, with an emphasis on sound engineering solutions.  The roof receives no irrigation and the maintenance requirements are minimal.
