Since the 1990s, Regional Growth Centers (RGCs) have played a central role in the growth strategy of the Puget Sound region. There are now 29, along with nine manufacturing/industrial centers (MICs) and other local or county- designated centers. Centers are a mechanism to focus growth and prioritize transportation investments. But the performance of centers is varied. Some, including the six centers in Seattle and downtown Bellevue, have far outperformed others where growth is anemic or non-existent.
