Washington State University Low Impact Development Certificate Program


The Statewide LID Certificate Program awards two certificates: A Design Certificate for design and installation of LID Best Management Practices (BMPs) and an Operations & Maintenance Certificate for long-term operations of LID facilities.

The LID Design Certificate is awarded for completing five intermediate level design courses

  • 3.2 - Intermediate LID Design: Bioretention
  • 3.3 - Intermediate LID Design: Permeable Pavement
  • 3.4 - Intermediate LID Topics: Site Assessment, Planning and Layout
  • 3.5 - Intermediate LID Design: Rainwater Collection Systems and Vegetated Roofs
  • 3.6 - Intermediate LID Design: Hydrologic Modeling


The LID Operations & Maintenance Certificate is awarded for completing one introductory and two advanced level maintenance courses

  • 2.1 - Introduction to LID for Inspection and Maintenance Staff
  • 5.0 - Advanced Long-Term Operations and Maintenance: Bioretention
  • 5.1 - Advanced Long-Term Operations and Maintenance: Permeable Pavement.


Course materials can be found on the Statewide LID Training Program page.

LID Design Certificate

The Design Certificate is intended for civil engineers, landscape architects, planners, and allied disciplines that design and install LID practices. Upon completion of the courses and assessments associated with the LID Design Certificate, participants will attain a breadth of knowledge necessary to better communicate across disciplines when designing and installing LID practices. Completion of the certificate will also increase technical knowledge, thereby improving the design, planning, implementation and review of public and private LID projects during each stage of project development. The certificate indicates that the individual has received (at the intermediate level) the latest design and installation concepts for LID practices; has a level of technical knowledge necessary to recognize design opportunities and challenges; and is better equipped to optimize LID systems.

LID Operations & Maintenance Certificate

The LID Operations and Maintenance Certificate is intended for local jurisdictions and third party enforcement and inspection personnel. Upon completion of the courses and assessments associated with the LID Operations and Maintenance Certificate, participants will attain a basic understanding of LID BMP design and function as well as an in-depth knowledge of inspection and maintenance, timing and tracking approaches. Completion of the certificate also provides participants with a breadth of knowledge to adaptively manage LID practices for effective long-term performance. The certificate indicates that the individual has received (at the intermediate level) the latest basic operations and maintenance concepts for LID practices; and has a level of technical knowledge necessary to design a maintenance regime and prescribe effective maintenance procedures.



Over the spring and summer of 2017, the Washington Statewide Low Impact Development Training Program (Statewide LID Training Program) - specifically the Low Impact Development Certificate Program (LID Certificate Program) - will be transitioning from a solely in-person training system to a hybrid (online & in-person) system.


From its inception, the Statewide LID Training Program was subsidized by the Washington State Department of Ecology. Ecology’s five-year investment in the program made courses essentially free to participants aside from a fee for meals and refreshments. Going forward beyond June 30, 2017, Ecology will no longer be covering the costs of running the LID Training Program.

Important features of the new training system are:

  • The bulk of the LID Certificate Program curriculum will be offered to participants as online modules via WSU and Blackboard Learn, where the certificate-track course assessments are currently housed.
  • Each module in the LID Certificate Program will still include a required full day in-person training to ensure participants get hands-on experience with LID design and/or long-term operations.
  • Fewer in-person classes will be offered – we anticipate approximately 2 offerings of each module per year – it will be important for participants to register for those dates as soon as possible, as courses are likely to fill up quickly.
  • Participants will need to register and pay for an entire LID Certificate course – the LID Design Certificate, and/or the LID Operations & Maintenance Certificate.
  • The costs of these two certificate tracks are currently being evaluated.
  • Registering for individual modules within those tracks will not be an option in the near-term.
  • Other courses not part of the LID Certificate Program may be offered individually with a yet-to-be-determined registration fee structure.

During this transition, current LID Certificate Program participants will still be able to access their Blackboard accounts and take the online assessments for the certificate-track courses they attended between 2014 and 2017. If a participant was actively pursuing a certificate and is missing only one required course due to a course being canceled or full, the Washington Stormwater Center will offer partial scholarships to cover upcoming costs. We appreciate your patience as we transition to a fully self-sufficient model for LID training. We aim to continue bringing you the most current and practical information related to the implementation of low impact development practices. Thank you for your continued support.
