Project Objectives:
• Establish relationships with traditional brownfield stakeholders
• Develop a tool to assess health equity and inform prioritization for brownfield clean up and redevelopment efforts
• Share findings and develop strategy for using the tool

Background
• What is a brownfield?– A former industrial or commercial site where future
use is affected by real or perceived environmental contamination
• Why are they significant to the health of our built environment?– Potential human health threat– Opportunity for infill development in areas where
developable land is scarce

Characterization of Brownfields in Multnomah County
• As many as 2,300 properties covering approximately 6,300 acres (7 percent of all commercial, mixed use and industrial zoned land within the metro UGB)
• Approximately ½ are within 1000 ft of sensitive environmental areas
• Three times more likely to be located in underserved area (Metro 2012)

Tool Development: Outline
Health equity composite measure•Purpose: Develop a GIS-based tool to assess health equity across Multnomah County and inform prioritization for brownfield clean up and redevelopment efforts.
•Objective:– Identify health indicators and construct a health equity composite
measure that identifies areas of health inequity within the county
– Overlay health equity composite with brownfield site map to identify brownfield sites in areas experiencing health inequity

Selection of Data Indicators
• Initial list was populated based on input from community
based organizations and traditional brownfield stakeholders
• Selected indicators that were available at the census tract level or smaller
• Prioritized locally-collected indicators • Incorporated components of EPA’s definition of
vulnerable populations (youth, seniors, poverty, communities of color, prevalence of chronic disease)

Next Steps
• Advocate: health equity informs brownfield site selection• Collaborate with community organizations in areas of high health
equity need• Use findings from tool to bolster application for federal cleanup
funds by demonstrating a community benefit• Refine tool
– Update health indicators
– Expand potential brownfield site data
– Make tool user-friendly—web-based platform
