Low Impact Development Program

Welcome to the WSU Puyallup Low Impact Development Research Program

The mission of the WSU Puyallup LID Research Program is to reduce the impacts of stormwater on streams, lakes, wetlands, and coastal areas through effective, research-based application of LID management principles and practices.

The mission of the program is accomplished through several objectives including:
  • Develop a living laboratory with full-scale, replicated LID management practices that serves a center for LID demonstration and education.
  • Conduct detailed and long-term research examining:
    1. Flow control and water quality treatment characteristics of permeable pavement and bioretention systems.
    2. Physical and biological characteristics of bioretention soil.
    3. Physical and biological influence of plants on bioretention flow and water quality treatment performance.
  • Use research data to evaluate and optimize the flow control and water quality treatment characteristics of LID management practices.
  • Use research data to develop or refine models to predict LID performance at the site and landscape scales. Evaluate the ability of LID practices to directly reduce or eliminate the impacts of stormwater pollutants on aquatic organisms.
  • Distribute research data and design experience to stormwater designers and managers through various venues including the web, technical journals and manuals, annual reviews and workshops.

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

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.
