다국어 초록 (Multilingual Abstract)

Purpose of the Research the research aims to evaluate urban renewal program of large-scale low-density apartment complexes for 100,000 households in the Southeastern area of Seoul in terms of residential environment quality, housing supply effect, and sound urban development. And, the research identifies public responses on the planning process and proposes to improve urban renewal program by compare before and after under the existing low. To improve quality of residential environment, it focuses on the quality of residential environment above a certain level. Then, in terms of strengthening the housing supply effect, it emphasizes stabilization of housing market and benefits of the residents. Next, to induce sound urban development, it checks the consistency with balanced regional development and urban management policies of Seoul Metropolitan government. 2. Reseach findings：Positive and negative aspects of urban renewal program, and effects of public responses Positive aspects include realization of high-density land use suitable to the areal characteristics, supply of plenty of housing stocks (33,000 housing units), and raise up of regional image. Negative aspects contain large-scale reduction of small-size housing stocks (39,000 units) resulting in the shortage of affordable housing and deepening of regional disparity widening income ifferential between southeastern part of Seoul and the rest. Effects of public responses includes application of F.A,R. 270~285% downed from 400% by Seoul Metropolitan Government, induction of forming pedestrian green network on the ground level by accommodating underground parking garage in the planning process. and installment of Committee on Time Adjustment of Urban Renewal Projects from 2002 to 2004, preventing concentration of many renewal projects at the same time and dispersing them. At first, in order to keep residential environment at a certain level maximum of F.A.R. applies below 250 percent while mailtaining existing zoning. This rule must keep even when incentive is given due to the provision of public rental housing. Then, it is encouraged development of adequate density in the existing superblock with each side less than 250m by laying out roads appropriately. Next, current system is amended to secure affordable housing in response to the recent housing demand. In terms of the regulation for size distribution, it is proposed to be amended to floor space less than 40㎡(60%) and less than 60㎡(40%) from that less than 60㎡(60%) and less than 85㎡(40%), while the public take the whole responsibility for public rental housing. Then, there still exists several large-scale low-density apartment complexes designated as urban renewal area and 59,000 housing units are estimated to be constructed by these complexes. Thus, the research suggests the installment of Committee on Time Adjustment of Urban Renewal Projects and the size of renewal should be no more than 3,000 units. Finally, Seoul Metropolitan Government (SMG) should pursue affordable housing policy in the southeastern area of Seoul for the balanced regional development, especially promoting supply with small-sized housing. Thus, SMG should give priority on affordable housing policy in this area.
