Benchmade Knife Company Parking Lot

Oregon City, Oregon

Anderson Associates was responsible for the planting and irrigation design for a new parking lot at the Benchmade Knife Headquarters.  Design included vegetated swales and rain gardens that received storm water runoff from the parking lot where the plants helped clean the water of toxins and provided for controlled drainage during peak storm conditions.  The project construction was completed in 2013.

Completed in 2007, the cottages were a second phase of the assisted living campus.  Runoff from the roofs and parking lot is directed to a large water quality planter where the water slowly percolates in to the ground that is planted with native, seasonally water tolerant species.
