As an urban area grows, it expands beyond its formal administrative boundary. This expansion can be seen in many cities around the world, not only in developing regions. "The administrative boundaries of cities no longer reflect the physical, social, economic, cultural or environmental reality of urban development and new forms of flexible governance are needed“ (EU, 2011). As Seoul Metropolitan Area (SMA) grew from approximately 2 million inhabitants in 1960 to 20 million in 2000, SMA confronted various multi-level, multi-city issues which must be solved in order to achieve sustainable urban development. This paper discusses SMA's experiences in three multi-level, multi-city metropolitan areas including urban planning, solid waste management, and water management. Especially in the explosive growth of the early urbanization phase, vertical coordination — led mainly by central government working with local and regional governments — was required and effective in solving metropolitan issues. As the urbanization matures, local and regional governments can resolve many metropolitan problems through horizontal coordination, or between governments, instead.
