As ballots arrive today in Portland mailboxes for a hard-fought ballot initiative (Measure 26-156) that would remove water, sewer and stormwater overflow operations from city oversight, one issue has attracted little notice in the billion-dollar battle over managing the city’s pipes.
That’s the comparative trickle of stormwater management fees that have been used not for pipes and gutters but for in-street bioswales — the basins lined with native plants that clean local rivers by reducing storm runoff. These bioswales also double as traffic-calming islands and intersection diverters that improve bike safety. It’s that transportation safety element that led former Portland Mayor Sam Adams to call the bioswales a “double win” and set aside $20 million for their construction as part of the Bike Plan for 2030 when it was adopted in 2010.
