Low Impact Development Program

Welcome to the WSU Puyallup Low Impact Development Research Program

WSU’s Puyallup LID Research Program is one of the largest installations in the nation. The program focuses on the rapidly expanding field of low impact development or green stormwater infrastructure. WSU offers the unique capability to conduct long-term research on full-scale, replicated bioretention and permeable pavement facilities.

The mission of the WSU Puyallup Low Impact Development (LID) Research Program is to reduce the impacts of stormwater on streams, lakes, wetlands, coastal areas and food through effective, research-based application of LID principles. These approaches are part of a larger suite of land and water management tools. We also  provide education and outreach to the community on sustainable stormwater practices.

The mission of the program is accomplished through demonstration sites, research and collaboration with partners. This includes: :
  • A living laboratory with full-scale, replicated LID management practices.
  • Ongoing  long-term research examining:
    1. Flow control and water quality treatment of permeable pavement and bioretention systems.
    2. Physical and biological characteristics of bioretention soil; and
    3. Physical and biological influence of plants on bioretention flow and water quality treatment performance.
  • Using research data to refine computational models to predict LID performance at the site and landscape scale.
  • Evaluating the ability of LID practices to directly reduce or eliminate the impacts of stormwater pollutants on aquatic organisms.
  • Disseminating research to stormwater designers and managers through online resources, technical journals, workshops, fact sheets and curricula; and
  • Providing LID training, resources and outreach to a wide variety of audiences

LID Project Database

Sharing lessons-learned and project successes is as important as sharing research data that your project is based on. As part of our information-sharing efforts, we are compiling a database of Low Impact Development Projects in the Northwest.
