A Study on the Sustainable Urban Redevelopment Structure Based on the Garden City: Focused on the Battery Park City and Hudson Yards Project in U.S.

Sustainability is an important topic from the perspective of cities as a common international task related to the survival of humanity. Especially, this topic is critical from an urban redevelopment perspective. The garden city model, suggest by Howard, provides the theoretical foundation needed for sustainable city construction. This paper proposes a sustainable urban redevelopment structure to analyzing the garden city model and cases evaluated as successful redevelopment projects: Battery Park City and Hudson Yards. Our proposal is as follows: First, urban redevelopment projects should adopt the land or superficies lease method. This method creates a positive feedback system that converts profits from the land into public resources and reinvests them to the city. Second, a public corporation should establish for each urban project. This corporation manages urban development projects as well as maintains the city after the project is complete. This method can alleviate the inefficiency and agency problems from a bloated organization that has excessive authority. Third, the government should reflect the above proposal to smart city construction, a new urban paradigm. The usability of the garden city model proves through the United States case. Therefore, adopt our proposal can strengthen city construction competitiveness.
