Impact Models ask what will be affected by a change in the place. It may be the most complex model of the second iteration. The geodesign team is asked to look into the future and imagine what qualities of the place will be impacted (changed) if the strategy selected by the team is implemented. For example, will the change impact environmental conditions, economic patterns, or transportation connections? At large scales, changes in the landscape may affect many different social, economic, or environmental systems. More importantly, what and how qualities will be affected is linked to what type of change occurs and how that may influence decisions. The need for inter-connectivity and dependence between models of the second iteration suggests how complex the geodesign process may become.
