Jacqueline Bleicher states that the community you’re working with knows best what’s not working and how to fix it. “Often their ideas are better, more salient, comprehensive and viable than some of the ideas being imposed upon them.” In this chapter of Our City she gives the reader tactics and insights on how to work with communities as experts of their built environment. It offers an approach on how to engage and consult with communities effectively to build trust and relationships. But also on organising and mobilising the community to translate their ideas and visions into built environment improvements. This is a must-read for any placemaker that wants to know more about community expertise in depth.
