The Portland Bureau of Transportation composts more than 5,000 tons of leaves collected through the City's Leaf Day program every year. Removing leaves from our streets is critical to maintaining safe streets as they can result in clogged storm drains, flooded intersections and slippery streets.
Sunderland Yard is currently closed to public sales due to Covid-19.
Sunderland Yard is located at 9325 NE Sunderland Road. You can call the facility at (503) 823-3500.
Every other month the final compost is monitored for quality, maturation, and sizing, per the United States Compost Council’s (USCC) monitoring guidelines. The facility has been a member of the USCC since 2007.
More about Portland's Leaf Day Compost
The City of Portland's Leaf Day leaf collection program begins early November and runs through mid-December. This program focuses on picking up the leaves that fall onto streets. Removing leaves from streets helps reduce slippery road conditions, increasing the safety of motorists, pedestrians, and bicyclists. Street leaf removal also reduces street flooding caused by clogged catch basins (grated storm drains). The City infrastructure also benefits from the reduced amount of leaves entering the storm drains.
Our compost turner has a restacking system that allows for a single pass for turning and restacking the compost. During the turning process the compost is aerated and, because of our frequent rain fall, water is added. The temperature and moisture content of the composting leaves are monitored daily to determine when to turn the pile to facilitate the composting process.
The final compost product is used by City crews for soil amendment (mixed with soil in areas in preparation for revegetation), erosion control in areas with exposed soil (e.g., roadside ditches and maintenance projects, etc.), donated to community gardens and sold to the public.
