working green for clean rivers

Portland’s Grey to Green initiative is expanding the city’s green infrastructure to sustainably manage stormwater runoff, stop the spread of invasive plants, restore native vegetation, protect sensitive natural areas, and replace culverts that impede fish passage.

Funding of the initiative began July 1, 2008 and the city invested $5 million in the first year of Grey to Green. The investment over five years will be $50 million to make stormwater management more sustainable, restore watershed health, and enhance Portland’s livability.
