TOUR REFERENCE MATERIALS
COTE hosted a van tour of four North Seattle bioretention facilities on Wednesday, September 25, 3–6pm, offering landscape architects 2.5 LA CES Professional Development Hours (PDHs). Below are the tour description and links to a tour summary, Google Map of the route, and session handouts.
Bioretention and similar practices, such as bioinfiltration, are becoming the most frequently used tools to manage stormwater in urbanized watersheds. The success of this approach to stormwater management is strongly tied to appropriate plant selection and planting design. Plants perform key processes in these facilities and also have critical roles in safety, aesthetics, and habitat. Nonetheless, many design challenges persist for this practice, including vegetation selection.
WASLA is pleased to offer this field tour emphasizing the use of plants in bioretention and water quality facilities. Targeted to landscape architects and allied professionals, the tour will visit select North Seattle stormwater facilities that illustrate issues, challenges, and evolution of plant selection, planting design, and maintenance for these unique landscapes. Our presenters will offer insights and experience from projects that have made the City of Seattle a national leader in stormwater management. Participants will engage in great conversation about what works and why, as well as the resulting implications for long-term performance and life-cycle costs of these multi-functional sites.
This tour starts at the Thornton Creek Water Quality Channel (near the Northgate TC and North Seattle Park & Ride), then continues by van to the Linden Avenue North Complete Street Project, Broadview Green Grid, and Piper Village bioswales on 1st Ave NW and Palatine Ave N in Greenwood.
