Yes it is and it isn't some little parking lot median it is on a good size street. We were in Vancouver last summer and the city is just amazing. There were rain gardens around the street drains, elaborate planted crosswalks and roof top gardens with full sized trees on them.
You can see in this one the opening at the curve to direct the water into the Rain garden and there is a good sized street drain in the middle .
This is a crosswalk planting it is at an intersection of several streets and you can stop and wait to get across the next street. Can't see the walkway but it is there.
This garden is on the 3rd floor rooftop of the hotel we stayed at.
