WASHINGTON STORMWATER CENTER | PUYALLUP, WA

WASHINGTON STORMWATER CENTER | PUYALLUP, WA

Owner: Washington State University
SvR Role: Landscape Architecture & Civil Engineering
Construction Cost: $2 million
Start Date: 2007
End Date: 2010

SvR helped Washington State University (WSU) win a $1 million matching grant from the Department of Ecology to research and demonstrate bioretention and porous pavement technologies at the Washington Stormwater Center. Then, in close collaboration with leading soil, plant and hydrology researchers at WSU, SvR designed and engineered this pioneering research facility. The Center’s designed experiments include:
• A parking lot with test cells to evaluate fl ow control and water quality performance of porous asphalt and pervious concrete.
• A grid of rain gardens comparing the water quality and flow control performance of plant palettes and maintenance regimes.
• A gallery of soil mesocosms comparing the performance of various soil mixtures.

These LID stormwater features allow in-depth and long-term research into the effectiveness of green stormwater infrastructure, providing relevant, high-quality data that will help improve policy and design.
