Construction waste is a major element to consider
when diverting materials that go to the landfill
Reducing the amount of material needed and
recycling content can significantly decrease waste
Prefabricated components are another great method
of reducing material scraps and packaging

Regionally extracted and manufactured materials
include the total cost of materials within a 500 mile
radius
Pre-and post-consumer recycled materials include
the copper cladding, handrails, bicycle racks,
and more
An educational outreach program was implemented at
City Hall including guided tours and brochures to
educate the public on sustainable solutions
Where does regional material come
from?Almost $5 million of the material is
regionally purchased from within
500 miles of the site
