Inside Portland’s Green Stormwater Infrastructure Portland, Oregon, has become a leader in handling the water that falls from the sky with a comprehensive green stormwater infrastructure. The city's Bureau of Environmental Services (BES) incorporates natural elements such as rain gardens, ecoroofs, and soil filtration into the combined system. This complexity is due to the topography and geology of Portland's topography, which makes it more difficult for one to keep rainwater out of the combined sewer. The infrastructure has led to a 35% reduction in stormwater volume going into the city's combined sewer, with over 56,000 disconnected downspouts contributing to over 1.2B Gallons of stormwater removed per year. Property owners can receive a discount on their stormwater portion of their water bill through the Clean River Rewards program for maintaining features such features such as ecorooofs, storm basins, and a tree canopy. The most consecutive days with at least 0.01 inch of rain recorded in Portland, January 1970, was January 22.
