The Science of LID: Washington Stormwater Center Dedication

SvR’s Peg Staeheli, Kathy Gwilym, and Nate Cormier attended the dedication of the Washington Stormwater Center, formerly the Washington State University-Puyallup LID Research Center, on March 20, 2011. SvR worked with leading soil, plant, and hydrology researchers to design and engineer this pioneering research facility. The Center’s “designed experiments” include:

  • a parking lot with test cells to evaluate flow 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 various plant palettes and maintenance regimes
  • a gallery of soil mesocosms comparing the performance of various soil mixtures

Taken together, these LID stormwater features will 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. The event included speeches by Congressman Norm Dicks, WSU President Elson Floyd, and EPA Regional Director Dennis McLerran, among others. The event also celebrated the announcement of the Center as the Pacific Northwest location for the EPA’s Green Infrastructure Partnership, a program to disseminate leading research and technical information nationwide.
