In an effort to manage excess rainwater and sewage spills at Seattle’s Barton Combined Sewer Overflow (CSO), officials have pulled out a small army of little red wagons to help illustrate green infrastructure improvements for residents. According to Sightline Daily, officials presented residents with rain garden maps and rolled out life-size tarps along the road to show the dimensions of planned bioswales and how they would interact with residents’ front yards and sidewalks. These swales can soak up large quantities of stormwater, helping prevent discharges of polluted water from the combined rainwater and sewage system. (Photo: Vineyard Adventures / Flickr)
