The session will explore recent British experiences in deploying scenario planning at the sub-city settlement scale. Sustainable growth strategies have not been practiced much in UK land use planning, and planner have been taught that attempting to predict the future and using top-down housing targets rarely works. The result is uncoordinated, unsustainable patterns of new development that turn many communities into NIMBYs. We will look at two case studies of high-growth settlements in the UK that have successfully used scenarios to engage with their communities and stakeholders to shape their growth plans.
