Sites
For this first demonstration, we have two sites located in the Tualatin River Basin.
Project Summaries

Both sites had heavy clay soils and are busily used public parking lots.

Tualatin Hills Parks & Recreation District (THPRD) Redevelopment

The THPRD site was a complete redevelopment. At the point that we presented our idea to incorporate trees into parking lots, a plan was already underway to remove all the existing asphalt in the parking lot and replace it with pervious concrete. We added our Parking Forest as an overlay onto the project, adding 15 trees to the new parking lot.

Portland Community College (PCC) Retrofit

The site at PCC was an existing conventional asphalt parking lot, but most of it was left in place. Only a small 12' wide by 34' long piece of pavement was disturbed and 8' of that width of pavement was replaced to ensure that the final parking stall would be adequate.

While the postal addresses seem to indicate that these are both located within the jurisdiction of Portland, the THPRD site is actually under the jurisdiction of the City of Beaverton and Clean Water Services. Please contact us if you'd like more information about permitting on these projects.
