This study aims to prove the influence of residential rezoning through analyzing the process of the residential rezoning and the change of development pattern after the year of 2000.
This study considers the process of the residential rezoning and sees the gap between planning criteria of residential rezoning and actual condition which is rezoned. And building permit data(2001~2006) of 25 boroughs in Seoul are analyzed to define changes of development pattern in residential area through GIS and ANOVA test analysis. This result shows how much residential rezoning is coincide with the original purpose and also draws the meaning and limitation of residential rezoning.
The major findings of this research can be summarized as follows.
First, the planning criteria of rezoning is characterized by harmonizing planning-oriented elements and real condition. Prior negotiation between Seoul metropolitan government and 25 borough governments in the process of rezoning is also included to show each borough's unique statement and planning willingness.
Second, residential development pattern after rezoning shows that the number of building permit is decreased. Residential use has more decreased than non residential use, so the ratio of residential use increased about 20%. The trend of building permit is displayed differently in housing type of each zone. And after rezoning, the ratio of detached housing buildings which was permitted increased in the 1st residential zone and the 2nd residential area(under 7 story building regulation), and apartments increased in the 2nd residential area(under 12 story building regulation) and the 3rd residential area.
Third, the lot size is increased in most residential developments, but building coverage ratio, floor area ratio(FAR), and Building Height are decreased. This trend shows a little bit different among rezoned areas, but the similar trend is shown in the whole residential area.
Fourth, two types of development pattern changes are revealed after rezoning. One pattern change has characteristic that is the increase of lot size but the decrease of building coverage ratio, floor area ratio(FAR), and building height. The other pattern change is the increase of lot size and stories but the decrease of building coverage ratio and floor area ratio(FAR). This can be explained by the movement of developers who want to increase the development size and to heighten the stories to have development profit under land use regulation reinforcement.
Based on the findings of the research, suggests for the systematic management of residential area in Seoul as follows.
First, residential rezoning shows coincidence with the original purpose which promote the amenity of residential environment. However, the planning criteria of rezoning needs to be revised to prevent the abrupt change of environment around residential development.
Second, the increase of non-residential use after rezoning should be concerned. To make up for this concern, the influence of non-residential use on residential environments should be carefully considered to complement the provisions of permitted use in the each residential area.
Third, the lot size has been increased since residential rezoning. Artificial large development through merging lots may not be desirable due to transforming the existing urban form, so the negative effect of increasing lot size should be examined to complement the political system.
