    AWRA-WA Seattle September 2019 Dinner Meeting:

    Bioretention Hydrologic Performance Monitoring Studies I & II: Findings from Twenty Facilities in Western Washington

    Speaker: Bill Taylor, Raedeke Associates, Inc.

     Monday, September 23rd, 2019

    1201 1st Ave S, Seattle, WA 98134

     5:30 PM to 8:00 PM (presentation begins at 7:00)

    AbstractBioretention facilities can be an important part of stormwater management within site development plans. If designed, constructed, and maintained properly, they can provide water quality treatment and flow control to meet the Department of Ecology’s stormwater requirements.

    Until these two monitoring studies were funded by the NPDES Stormwater permittees via the Strategic Action Monitoring (, very little was documented about how constructed bioretention facilities actually performed. Do they meet the design expectations of the engineers? Do they meet the modeling expectations using the required design model?

    Bill Taylor and project team members have conducted a hydrologic mass balance monitoring study of twenty constructed bioretention facilities located throughout Western Washington – with sites from Bellingham to Olympia, Poulsbo to Issaquah.

    Bill and team members will present results from the monitoring and modeling of these constructed sites. Results include the measured flows and infiltration rates passing through the units, vegetation community composition and success, and modeling observations. The results offer suggestions to engineers, hydrogeologists, and landscape architects for better designs for future facilities.

    Bio: Bill has 30 years professional experience as an aquatic sciences consultant, covering field monitoring and scientific analysis in stormwater quality, fisheries and hydrology in the Pacific Northwest. His primary area of work over the last thirty years has been stormwater monitoring design and implementation, NPDES permit compliance, and monitoring estuary and stream habitats and restoration sites for environmental protection.

    The 2019 AWRA-WA State Conference is titled “Water Resources Planning and Implementation: Challenges, Complexity, and Uncertainty” and will occur on October 1, 2019 at The Mountaineers in Seattle, WA. The conference will highlight the role of water resource planning efforts in Washington in addressing competing needs and sources of future uncertainty such as climate change.  Interdisciplinary perspectives will be presented on the challenges and success stories of past water resource planning efforts and effective plan implementation.  The conference sessions will be as follows.  First, Will Stelle from Washington Water Trust will kick off the conference with a keynote speech, sharing his insights into planning in Washington State.  Then Session 1 will start with a historical perspective on planning in Washington, followed by presentations on lessons learned from Watershed Planning that are cross-cutting and relevant to multiple watersheds. Session 2 will focus on the Hirst decision and related planning activities and methodologies, such as Net Ecological Benefits.  Session 3 will cover managing uncertainty in planning efforts, including climate change.  Session 4 will cover significant planning efforts in Washington other than Watershed Planning, such as the Yakima Integrated Plan.  And Session 5 will be panel discussion with a view towards future planning and how to make it more effective.
