Portland’s Halloween revelers may have gotten soaked in the heavy rainstorm that day, but there is good environmental news to report.
In the past, a rainstorm like we had last Saturday would have brought large volumes of stormwater, oil, and grease from I-5 and other roads and washed it directly into Tryon Creek. But this time, a large amount of runoff from the rainstorm was captured, slowed and filtered by the terraced raingarden project built by Environmental Services and the Oregon Department of Transportation.
One of BES’s landscape architects who worked on the project bravely ventured out in Saturday’s rain to see how the facility was performing and shared these photos:
