


CONCLUSIONS
High convenience statewide, lacking in some
areas
 The most underserved residents include those
living in Gilliam, Douglas, Polk, and Lincoln
counties
 Site Selection and Convenience Analysis tool
can help ensure that future programs achieve
high convenience with limited facilities.

RECOMMENDATIONS
Plan yearly collection event in Gilliam county
 Establish collection sites in Polk, Douglas, and
Lincoln counties if funds become available
 If and when potential sites are chosen, use tool
to select the most beneficial ones or to guide
the order of activation.
