I had the recent opportunity to swing by an project (designed in 2009 while at GreenWorks) for the rain garden gateway along Warner-Milne Road in Oregon City, Oregon – which was installed last year. A new roadway alignment created a wide area between the existing right-of-way and the new curb, allowing for the integration of a large green street feature to manage impervious surfaces. In addition to the stormwater function, the location on one of the main roadways through Oregon City gave it the potential to act as a gateway for the municipal offices nearby. Congrats to the City of Oregon City, GreenWorks PC, and Wallis Engineering for realizing this exciting project.
The implementation of large corten panels acted as vertical elements that were legible from the adjacent pedestrian and vehicular users.
These curving walls gave shape to the sinuous vegetated garden area, punctuated by arching stone weirs with two different gravel types delineating low and high flow conditions.
