Participants first learned, in class, about what a rain garden is and how they function. (Note: an Ocean Friendly Garden (OFG) is a rain garden-plus - see OFG criteria for details.) Next, they were shown how to site one appropriately by calculating drainage area and local soil infiltration. Lastly, they were taught about using native or climate adapted plants in rain garden.
From a water quality standpoint, capturing and cleansing the first inch of a rainstorm after there's been a dry period - known as the “first flush” - is OFG's main focus. Even small landscapes can absorb the first flush.
Maria next took the group outside to do do an infiltration test (pictured at left). For those who were not able to attend, or did but need a refresher, helpful links with information from the workshop were posted by Surfrider Foundation's Oregon Policy Manager, Gus Gates, in this blog post.
The Chapter OFG Program's next step is to work with Gus to identify a workshop attendee wanting to create an OFG at their home or business, and done through a Garden Assistance Party format. Through this barn-raising-like format, homeowners/renters, government reps and landscape professionals get hands-on experience in both how to create an OFG and how to work as a team to help others.
The workshop was generously sponsored by the Siuslaw Watershed Council and the Siuslaw Soil and Water Conservation District (SWCD). It's cool to see collaboration with SWCDs, as happened with the Newport, OR and Portland, OR Chapter classes, workshops and workdays.
