Washougal Town Square 1700 Main Street • Washougal, Washington

The basic stormwater management concept at the Washougal Town Square courtyard is capture, convey, cleanse, detain and discharge through effective separation and dispersal of roof runoff into management systems throughout the space.  Roof runoff (as well as some rain directly from the sky) is carried by downspouts and drain pipes to 5 separate flow-through detention planters around the edges of the space, while 3 additional flow-through planters are fed by a long, sculptural scupper.  The planters cleanse rainwater and hold it before it is discharged into the city’s stormwater system.
