Since fundamental structures of natural environment had not been altered deeply throughout the development process of Senri New Town, some segments of those structures are still underlying in open spaces including most urban parks of the area. Detailed research into the procedures of land formation in initial development process indicates that area and volume of earthworks were kept minimum based on the original topographical conditions, and as a result, hydraulic system of the area was preserved. These conditions affect planning of the parks, and the areas that contain the original landform and vegetation were located according to the land formation. Also, some athletic grounds in the parks were placed in the area where irrigation ponds were encroached nearby the original topography and vegetation. Based on those notions, the following points are acknowledged as proposals for restructuring open space system in the area for future. (1) Parks and open spaces should be restored in the way to preserve and enhance the regional hydraulic system, which has an indispensable value in the environment. (2) Land use pattern should be reorganized through the renewal process of collective housing sites including conversion of substantial area to open space. (3) Natural environment of the areas designated to athletic grounds by encroaching irrigation ponds should be revitalized through integrating water features of various kinds into functions of the existing parks.
