The City of Portland is walking its talk. The historic City Hall will receive an eco-roof to underscore the city’s Green Building Policy and its commitment to sustainability.

Approved last week by the Historic Landmarks Commission, the eco-roof design must be compatible with the 1895 building’s historic character, including views from the surrounding towers above. Mayer/Reed’s formal layout creates panels of framed sedum plantings over areas of roof that can withstand the extra saturated weight.
As part of a roof replacement and exterior surfaces renovation led by Architectural Resources Group, Mayer/Reed designed the eco-roof to be economical and low maintenance, while maximizing ecological and aesthetic benefits. Initially, the team wasn’t sure that an eco-roof would work due to weight, but then determined that a thin profile cinder system would meet requirements.

The eco-roof will feature a mix of 12 drought-tolerant plant species including sedum and flowering bulbs to create seasonal interest. At certain times of the year, the vegetation will be take on a red hue, rather than green.


After over two years of design, demolition is well under way at the Grant campus. The removal of select, outdated building additions has begun to allow visual and physical connections between the campus and adjacent
We look forward to seeing new outdoor spaces for the school and community take shape out of the current landscape of mud and rubble.
