On September 1, Environmental Services resumed accepting treebate applications. That marks the start of the fourth year of the program. Portland residents who plant eligible trees in their yards can get a sewer bill credit of up to $50 depending on the mature size of the tree. 

Environmental Services has granted Treebates for more than 1,750 new trees since the program began. One out of every five Treebate trees is evergreen, one out of six is a fruit or nut tree, and one out of eight is a species native to the Portland area.

Columbia Slough Training Day

Up close, personal and paddling - that's the way 17 ecologists, engineers, cleanup specialists, watershed managers and scientists learned about the Lower Columbia Slough's 9 miles on September 7th.  City, Port and staff from other agencies working to recover and restore the waterway covered every inch of the Slough from NE 18TH street to Kelley Point Park. "Everything has an ecological niche... I was glad to see both incised waterway and mudflats," said one paddler. "This is a jewel next to heavy industry," said another.
