The Urban Land Institute (ULI) and the Cascadia Innovation Corridor (CIC) will examine the vision and prospects for responsible growth patterns in the Cascadia bioregion in this compelling virtual series. The Next 5,000,000 refers to the striking number of people that will call Cascadia their new home by ±2050. Opportunity-seekers, lifestyle-chasers, immigrants, domestic migrants and climate refugees will flow into Cascadia, putting even more pressure on the I-5 corridor. We have a unique chance to prepare for this by fostering an equitable, intelligent, well-connected megaregion, from the Lower Mainland of British Columbia to the Portland Metropolitan area.
