ADOPTING SOME MEASURES TO MAKE MORE COMPACT URBAN AREA THROUGH URBAN FACILITY RELOCATION POLICY

Abstract

 This paper focuses on Japanese version of compact city plan, Richi-Tekiseika-Keikaku in Japanese, which aims at making more compact urban area than existing one by implementing limited residential area, Kyoju-Yudou-Kuiki, and urban activity area, Toshi-Kinou-Yudou-Kuiki. The limited residential area is one that a citizen can build her house outside of the area but must resister only when she would build more than three houses together or one thousand square meters. So, the area is not strict enough to control urban expansion due to unwillingness of public sector to handle private property right. The urban activity area is one that make various urban activities concentrated into the area, expecting citizens to relocate themselves near there. Therefore, with this two concepts, compact city would be realized systematically and logically. However, we think that it would be necessary to try to make the limited residential area compact by making existing urban activities within the area, not being naive to think that encouraging urban activities to be relocated into urban activity area can lead people to near there and ultimately compact urban area would be realized. We tried to identify which activity could lure citizens to move when the activity would decide to be relocated near or into the urban activity area. We collected population and urban activity data and formatted them into 500m meshes. With these data, we calculated Coefficient of Variation (CV) and did statistical analysis to find out how much each municipality feasibly set numerical goals for compact urban area. It would be unrealistic to pursue making resident area more compact with only one single urban activity’s relocation and need combining several urban activities’ relocations. We proposed PDCA cycle management, Plan – Do – Check – Action, to reach at compact city goal.
