도시정비사업 활성화를 위한 사전타당성검토제도 개선방안 연구

도시정비사업의 사전타당성검토제도 개선방안을 연구했다.

Urban Improvement projects were promoted according to the 「Urban Planning Act」 in 1962, and the 「Urban Redevelopment Act」 was enacted in 1977 to promote the project. However, using the insufficient legal system, two or more promotion committees, supported by the construction companies, were formed in one district, and it spread to the mass production of the construction company's proxy battles, which intensified conflicts between residents and caused various corruptions, which became a social problem.

Accordingly, the 「Act On The Improvement Of Urban Areas And Residential Environments」 specializing in housing redevelopment, housing reconstruction, and residential environment improvement projects was enacted and implemented from July 2003. In addition, in large cities with a population of 500,000 or more, the establishment of a master plan for urban and residential environment improvement was made compulsory and an area to be rearranged was designated so that the maintenance project could be carried out.

Busan Metropolitan City promotes the existing sites through the 「2030 Busan Metropolitan City Urban and Residential Environment Reorganization Basic Plan」 announced in December 2019, but does not designate a new area to be renovated, and conducts a pre-feasibility review system based on the residential maintenance index. was introduced. As a result, pre-feasibility studies are currently being conducted in many areas at one time, and after two years have elapsed, research was conducted to suggest problems and improvement plans for the pre-feasibility review system.

As a result of investigating the progress of Busan Metropolitan City, as of March 2022, pre-feasibility reviews were in progress in 108 districts. Also, it was found that the procedure was being implemented by applying for a pre-feasibility review or that the application was being prepared. In order to identify the problem, a case analysis was conducted. The case analysis was carried out by dividing the pre-feasibility review deliberation completion area, deliberation reception area, and reception preparation area area, and the results of the case analysis are as follows. First, public confidence of the propelling entity is required.

Since the components of the promotion body are not stipulated, there is a phenomenon in which two or more promoters are configured in one area and are at odds with each other. Second, it is necessary to stipulate the standards of business agencies. It has been found that there are many cases in which business processes are hindered by selecting a business agency that does not meet certain qualifications. Third, there is a change in the reference date for calculating the right for a pre-feasibility review (prohibition of stock split).

In most sites, the building and the land are sold separately to acquire the sale right, or the stake is divided and owned over the minimum land area of ​60 m2 or more for which the member's sale right is recognized, or the multi-family house is converted to a multi-family house or the minimum-scale multi-family house is built. The increase in the number of owners of land, etc. and the sale rights of union members caused the cooperative's business feasibility to deteriorate. Fourth, the original purpose of determining the boundaries of the district was damaged.

There were problems such as the cost of additional work and opportunity cost due to the lengthy project period, as the license holder was requesting the contents of the architectural plan and traffic impact evaluation to the extent that it was deliberated according to the designation of the rearrangement area. Lastly, considering the case analysis, it seems necessary to establish a maintenance project integration support group that can play a central role in the maintenance project.

This should not only be able to adjust the speed of the pre-feasibility review progress zone, but also play the role of relief measures and support for various deliberation in areas that require maintenance but have low business feasibility and are difficult to proceed with the project. Urban redevelopment is a project that can serve both private and public interests. In terms of profit obtained by dividing the business center (members) and the public interest part, business operators largely improve the quality of life and increase asset values ​through the improvement of old and poor housing.

The standardization of underdeveloped areas includes improvement of urban aesthetics, securing rental housing, new housing sales in high-quality areas in the downtown area, and increase in local tax revenue. In order to protect these business operators and reduce trial and error from the initial stage of the project so as not to damage the public nature, system improvement or supplementation is required. In order to analyze the importance of problems and improvement plans through case analysis and in-depth interviews with experts, 42 people were surveyed for each of 6 people in 7 fields.

By weight analysis through the fuzzy confidence index using the Fuzzy-AHP method, the important priority for improvement methods was determined, and the sub-classification improvement method selection and reliability were verified. As an important priority for problems that need to be urgently improved, the first priority is the change of the pre-feasibility review right calculation base date (prohibition of share division).

As an improvement plan, change the current reference date for calculating the rights of union sales right to the date of receipt of the pre-feasibility review ward office, or change the date of approval of the probate by introducing a serial number inspection system for consent forms, and change it to be canceled if the application for designation of a rearrangement area is not made within one year should be announced For the 2nd priority, the procedure should be carried out in combination with the prior feasibility review and the designatio
