GreenWorks Presents "137 Green Street Facilities in 4 Days" at Fall 2010 APWA Conference

Dave Elkin and Tim Strand recently presented their work with the City of Portland's Columbia Slough Watershed group that produced an inventory of stormwater treatment facilities in four high priority stormwater outfall target areas within industrialized areas of the Columbia Slough Watershed. During a four day process, the project team evaluated 109 acres of public right-of-way and identified over 130 green street facilities that would potentially treat stormwater runoff from 39 acres of impermeable surfaces. The results of the inventory were cataloged in a Stormwater Inventory & Prioritization GIS database, which was used to evaluate facility performance, design & construction feasibility, cost information, and supplemental benefits for each facility.
