都心再開發事業의 公共用地確保計劃에 關한 硏究

도심재개발사업에서 공공용지 확보계획을 연구했다.

Not having been planned by design, central spaces of the Metropolis tend to have irregular and spontaneous forms which cause serious lack of infrastructure. So, urban renewal project are being carried to modernize these irregular spaces of the downtown areas. In process of the projects, however, several problems have been exposed because of discontent with broken principle of equity and graded maintenance rate of public spaces with which project operators should provide. The purpose of this paper is to find remedies by citing and investigating problems in urban renewal process. The problems of the maintenance rate of the public spaces in present urban renewal projects are as follows.

First, there are no definite enforcement regulations for maintenance rate of the public spaces compared with the building-to-land ratio and the volume-to-land ratio according to size and scale of urban renewal area. Second, large variance of the public land providing rates and no definite standards in several renewal area act against the principle of equity. Third, the difficulty of systematic maintenance of public spaces results in delay of project enforcement. Fourth, some problems related to retention areas cause delay of public space-maintenance and discontent with equity between land owners of retention areas and other renewal areas.

Fifth, need of public space-maintenance for educational facilities is urgent because of encouraging policy for residental district complex. The remedies to solve these problems are as follows. First, the building-to-land ratio and the volume-to-land ratio are to be applied differently in grades according to the maintenance rate of the public spaces. Second, the standards of providing rate of public lands are to be determined. The equity of developmental gains can be kept by support or imposition of urban renewal funds.

Third, it is recommended to encourage founding public facilities by designation of priority order for maintenance of public spaces and determination of detailed plan to make systematic maintenance of public lands. Fifth, it is also recommended to maintain about 1 school site in 3 or 4 adjacent areas jointly frist, then to secure additional sites by supporting urban renewal funds and to make return the funds later at the time of further enforcement of projects. Above problems and remedies are abstracted in practical business level about urban renewal projects and verified on the basis of several related papers and research materials.
