高蔵寺ニュータウン開発計画に及ぼした自然環境構造の影響

Abstract

Kozoji New Town is one of the earliest large-scale residential developments in Japan. The plan was based on a land readjustment project which took into consideration natural disasters such as Typhoon Vera, large-scale developments such as the Aichi Canal, and social situations such as the advance of motorization. The master plan for Kozoji New Town changed over time while continuing the search for an ideal form of replotting design and solutions for problems with the transport plans in consideration of the natural environment of the site, but eventually a unique plan was realized incorporating the valley’s large-scale main roads and pedestrian ways on the ridges branching out from the regional center which is concentrated in the one spot. In the process of changes in the master plan, the ‘natural environment’ of the site had considerable influence on the shedding of the neighborhood unit theory, the concentration and density of population and facilities in the centre and the pedestrian way connections. As Kozoji New Town made the local natural environment the fundamental structure of the new town, it became an opportunity for great changes in the attitudes towards planning spatial structures in subsequent new town planning, while continuing some development ideas from early New Town planning.
