Description
The Rain Garden is a vehicle for managing the rainwater run-off from the Oregon Convention Center's 5.5 acres of impervious roof surface. The 318-foot-long channel simulates a mountain stream with basalt columns and wetland plants like dwarf willow, redosier dogwood, sedges, rushes, and water iris. Terraced cobbled sedimentation basins slow the water, allowing sediments to filter out and increasing time for infiltration.
