Pringle Creek + the Gravel Verge

Building on some recent posts on the SEA streets in Seattle, and Crown Street in Vancouver, BC, a few images of Pringle Creek - the uber sustainable community in Salem, Oregon. A significant feature is the use of the gravel verges - popularized by Patrick Condon these curbless sections allow infiltration on the edges of streets, as well as reducing construction costs.

From their site: "Pringle Creek Community in Salem has one of the largest installations of pervious asphalt in the country. The green streets are narrower than conventional streets, using less materials to build and calming traffic. They have no curbs, which reduces construction costs and allows vegetated swales to capture, absorb and clean stormwater runoff."

The use of permeable asphalt and curb bulb-outs is sort of a belt and suspenders approach, but together creates a very unique environment and aids in traffic calming and the ability to manage greater amounts of stormwater runoff (and look, sidewalks!) It will be interesting to see how the permeability holds up during construction of the houses, which is slowly happening over time... slowly.

Another aspect of the community was the ability to route roadways, and limit impacts to existing large trees, giving a feel of a much more established community. And the rain gardens are waiting patiently for new residents to enjoy them.

It's definitely telling to see the interface with the porous and non-porous surfaces, here at one of the site entries. Also a quick video showing the performance of the permeable asphalt pavement. (both via the Pringle Creek Blog)
