This blog has dealt earlier with the logistics of doing an HIA but what does a workshop look like? One source is the Arden Hills Healthy City Planning Workshop Summary Report Appendices. This document contains images of each stage of the half-day workshop. Go to http://designforhealth.net/wp-content/uploads/2012/12/cases/HIA_ArdenHills_Appendices_3June2010.pdf and look at pages 33-36. More information about the process is available at: http://designforhealth.net/cases/ardenhillsworkshop.html.
