Dinner Meetings

Dinner meeting are generally held once per month on a weekday. Meetings provide an opportunity to mingle with other professionals, students, and people interested in water resources. Typically, dinner is provided followed by a one hour presentation by featured guests.

    Geologic, Soil and Groundwater Considerations in Bioretention Cell Design and Performance

    presented by
    Jennifer H. Saltonstall, Associated Earth Sciences, Inc.
     Tuesday, June 26, 2018

    Ivar's Salmon House

    Dinner - 6:30 PM to 7:00 PM
    Presentation - 7:00 PM to 8:00 PM


    We present key geologic, soil and groundwater considerations for design of bioretention cells and the results of hydrogeologic assessments and hydrologic performance monitoring on ten bioretention cells located throughout the Puget Lowland.  The work was in support of a regional bioretention infiltration effectiveness study conducted as part of the Stormwater Action Monitoring (SAM) Program, a collaborative, Western Washington regional stormwater monitoring program that is funded by more than 90 cities and counties, the ports of Seattle and Tacoma, and the Washington State Department of Transportation.  The bioretention cells are infiltration (artificial recharge) basins designed with a layer of compost-amended sand (bioretention soil) to provide water quality treatment.  The design of these cells uses a hydrologic model to size the facility based on inflow data and hydrogeologic parameters for the bioretention soil and native subsurface geologic unit.  This study collected field data on thickness, particle-size distribution and permeability of the bioretention soil mix and native subsurface geologic unit; evaluated the site hydrogeologic setting and installed shallow ground water level monitoring stations; and included field infiltration testing of each cell.  The field-measured parameters were collected to document the current condition of the cell relative to the as-built drawings and available background geotechnical information.  The information was used in WWHM2012 (Western Washington Hydrology Model, version 2012) modeling to compare the previously documented hydrologic design information with our field-collected information.

    About the speaker

    Jenny Saltonstall is a licensed Hydrogeologist in Washington State, a Principal at Associated Earth Sciences, Inc., and has consulted on Puget Sound area hydrogeology, geology, and geologic hazards assessments for both private and public sector clients since 1998.  She is a leader in stormwater infiltration feasibility and practical stormwater infiltration site investigation and design, both for shallow conventional systems and deep stormwater recharge Class V UIC wells.  Jenny is an expert in complex Puget Sound stratigraphy and has a fundamental understanding of subsurface “plumbing” system in our area from managing hundreds of infiltration projects from design through construction.  Jenny provides senior review for geologic and hydrogeologic studies, and is a regular contributor at technical conferences and has been an invited speaker on infiltration components for “green” storm water management seminars.  Outside of work, now that her kids are getting older, Jenny and family have begun backpacking again, spending time on the Olympic Coast and looking forward to the Cascades.
