following are Low Impact Development (LID) Workshops that are currently offered  

Statewide Low Impact Development Training Program LIDTrainingHeader2c

As a result of new NPDES municipal permit requirements regarding Low Impact Development (LID), the Washington State Department of Ecology is hosting a series of FREE LID technical trainings through June 2015. Trainings will be offered throughout the state at three levels – Introductory, Intermediate and Advanced - and will cover multiple LID topics. Read more…

WSU Technical Workshop Series                            


The WSU Puyallup Low Impact Development Program offers a variety of educational opportunities to the stormwater community throughout the year. In addition, we offer an Annual Review of local Low Impact Development Research and partner with other organizations offering LID education to local communities.

The Washington State University LID Technical Workshop Series provides the latest design guidelines, science, construction details, and practical experience necessary to properly design, build and maintain LID practices. All classes will be conducted at the Washington Stormwater Center on the WSU-Puyallup campus. Hands-on learning opportunities will augment the classwork. Instructors of the four, two-day workshops are regional experts. Read more…

LID Code Update and Integration Training


Start planning for your LID code review and update process or learn some new strategies for recharging your existing process. The Washington State Department of Ecology is hosting a series of 8 FREE trainings throughout the state. These trainings are designed to equip Phase II jurisdictions throughout Washington with the clear, relevant, and directly applicable knowledge and tools needed to update their codes and regulations, in compliance with the NPDES Municipal Stormwater permit requirements. In Eastern Washington, these trainings will provide a great opportunity for Phase II jurisdictions to learn how their current codes might conflict with LID practices, and how to update their codes to allow new and redevelopment projects to incorporate LID features.

Videos for Elected Officials

These short videos are designed for elected and other appointed officials. They’ll help explain what Low Impact Development (LID) is, and how new stormwater permit requirements will present Washington communities with both challenges and new opportunities. Watch and learn why this matters to your community!

Remember: LID code requirements differ between Eastern and Western Washington - talk to your Ecology permit manager if you have questions about your jurisdiction's responsibilities.

WSU Puyallup LID Research Center Annual Review

Each year we offer a one-day symposium that will review data from the past year's research at the Puyallup LID Facility and discuss future research potential. In addition, we invite researchers from across the nation to share and compare results. This review is a great opportunity to stay up to date on the most cutting edge-research in the field of Low Impact Development and Green Stormwater Infrastructure.

The 2012 and 2013 Washington State University (WSU) Low Impact Development Annual Reviews highlighted the latest research findings in Low Impact Development being conducted in the Puget Sound Region at the WSU Puyallup Research and Extension Center. Visiting green stormwater infrastructure specialists presented their current findings.
