Thousands of plants are now helping to clean and filter water throughout the Downtown Riverfront site. Rain gardens line all of the streets, including these which receive runoff from the Ferry Street Viaduct. These new gardens will create a significant improvement in the quality of water draining from the viaduct and directly into the Willamette River.
Creating new sidewalks involves cutting contraction joints into the concrete. These joints keep the concrete from creating its own cracks after it has cured.
