Hands-on Low Impact Development Workshop Scheduled

Sustainable Seattle and EOS Alliance are partnering to provide a hands-on low impact development workshop.

The rain running off our roofs, roads and yards is the biggest source of pollution entering Puget Sound’s water. We all contribute to this pollution, and we can all help solve this problem by applying Low Impact Development techniques that slow the runoff down and treat the water. To help you learn about and apply LID on your own property, Sustainable Seattle, in partnership with EOS Alliance, is offering a workshop that combines a class about the benefits and types of LID with a hands-on experience building a rain garden or bioswale so you can exactly what is involved.

Saturday, February 26th will be the theory and background day. We will cover what sustainable design is, what it means to you and its context in the neighborhood, city, region, nation and planet, and its nexus with Low Impact Development, before going into more detail about site assessment and design.

Sunday, February 27th will be the hands-on day. Participants will have a chance to enter their own property into a drawing, the winner of which will be the work site for the rest of the day. We will visit the winning site to do an initial survey, design what to build there to improve its stormwater handling, and spend the rest of the day building what we have designed.

Thank you to EOS Alliance for partnering with us on this workshop.

The schedule for the two days is below:

Saturday February 26

  • 10:30 am – noon: The first session will cover what sustainable design is, what it means to you and its context in the neighborhood, city, region, nation and planet, and its nexus with Low Impact Development.
  • 12 – 1:00 pm: Lunch and socialising. Bring a sack lunch and we’ll eat together.
  • 1:00 – 5:00 pm: Detailed discussion of Low Impact Design. Topics covered will include:
    • Site assessment
    • Soil analysis
    • Site hydrology
    • Site mapping & analysis
    • Site planning & layout
    • Site design

Sunday February 27

  • 9:00 am – noon: Optional site assessment field trip. We will have a drawing to pick a students house for the installation of a rain garden or other LID design solution. It is understood from the class syllabus that all those participating in the drawing will need to share in the cost and labor of building a rain garden. Participation in this is voluntary and is not part of the basic course syllabus. We will then arrange a field trip to that location for in field practice of site analysis and site planning based on the analysis principles learned.
  • 12 – 1:00 pm: Lunch indoors.
  • 1:00 – 5:00 pm: Construction. We will retrofit a class member’s house with a rain garden and/or bioswale. This is a hands-on physical exercise.
