This paper states about the regional system design to generate urban coexistency with natural features and followingly to bring safety and security on urban activities.
First, it realizes the grand network system development which perform the coincidence of urban activities flow with natural infrastructures such as the water basin formed by rivers and the bay. Continueingly, the urban open space and the urban landuse system will be requested to follow the coincidence. By this formation, the ecological balance and peoples life amenities must be regenerated in the urban environment. And also, urban activities will be vitalized by organic incentives from the newly balanced environment. In this balanced environment, the failsafe function of urban responses against disasters should be enhanced. The short of this supporting function was experienced at the big disaster of Hanshin-Awagi earthquake.
Scecondly, it institutes the inseparatable necessity of environmentally balanced local units such as leaves and branches of trees. Each units will support human life as a town and a neighborhood. The coexistence of this level will reply directly habitation needs and ways of real human life. For this purpose, the neighborhood system of the past newtown must be revaluated and improved by refreshed knowledge. Organic thinking and design for urban space is essential.
At last, it proposes eight points of guide-posts for the design. These points include the cohabitation urban system, the human scaled and behavioral balance intended urban space, the exchanging system among selfsupporting clusters, the redundant feature for urban infrastructure, the public facilities available as lifesaving points, the urban network by selfsupporting-multipolarized cities, the need of a metropolitan region adjusting authority for efficiencial realization and restructuring of regional traffic systems, the re-creation of intelligent function in the city center against decentralization of advanced research and educative functions.
