2025 SW Merlo Court, Beaverton
Planted with the appropriate native plants, the bio-retention swale shown to the right accepts sheet flow from Merlo Court, the curbless street in front of the facility and runoff from the ecoroof. Bioswales with native plants separate the rows of cars in the parking lots. Scuppers cascade runoff from the unplanted roof areas to rock piles in raingardens. Runoff from the service yard goes through teatment including oii-water separators before entering the large bioswales adjacent to Tualatin Hills Nature Park, shown below under construction. This large swale is now heavily planted with native plants. Monitoring of stormwater data from this site will help direct future development of LID technology.
Aloha Huber Park School – Rooftop to Raingarden
5000 S.W. 173rd Road
The new Aloha Huber Park Elementary School is harvesting rainwater from their roof to use in their rain garden. The garden beautifully mimics a natural stream with local native plants. Gutters made from blocks of concrete from a recycled sidewalk feed the stream from the downspouts and stream crossings are provided by large strategically placed stepping stones. The stream feeds into the creek along 170th St, Washington County’s stormwater treatment and restoration project that is lush with native plants. Designed by Art Graves of Chris Freshley Landscape Architects.
