청계천복원사업이 청계천주변 도시공간에 끼친영향 : 5.8km 청계천 복원주변 블록을 중심으로

청계천 복원사업이 주변 블록의 도시공간에 미친 영향을 분석했다.

In 2002, Candidate Lee Myung-bak, Seoul mayor, insisted that the Cheonggye high price be removed to restore the Cheonggyecheon stream. In the 2000s, when the highway, where 120,000 cars were driven a day, was lost, traffic congestion and controversy over the survival of 200,000 Cheonggyecheon merchants around the Cheonggyecheon area, but with the election of Lee Myung Bak in 2002, the Cheonggyecheon restoration project started to speed up. On July 1, 2003, the Cheonggye peak was demolished in 34 years. The reconstruction work was completed on October 1, 2005, which was two years and three months after the construction started.

The restoration of Cheonggyecheon, such as the citizens who welcomed the small natural waterways in the city, and the citizens who lost their life, were in the place filled with vehicles, and the good points and bad points came up. It has been 13 years since the Cheonggyecheon was restored artificially. The image of the Cheonggye Highway is disappearing to the citizens of Seoul and the effect of the Cheonggyecheon, which is familiar with the landscape of the city, across the city, has been investigated. In this study, we investigated how Cheonggyecheon restoration affects the surrounding urban space after completion of the restoration project of Cheonggyecheon in 2005.

For this, Digital terrain in 2000, and restored topography in Cheonggye stream in 2018. The comparison of the land area, the land area, the road area and the river area using the land use coefficient as a comparative element analyzed the changes in urban areas around Cheonggyecheon and analyzed the building area. First, city planning policies such as urban policy and urban environment improvement project, redevelopment of housing redevelopment, district planning area, etc. were influential on the change around Cheonggyecheon Stream.

In the case of the urban environment maintenance project and the reconstruction of the housing redevelopment, the change of the urban organization has occurred compared with the development of the small-scale development and the self-directed district unit planning area in the form of constructing the building on the specific land for the specific business operator. Housing redevelopment reconstruction is completed after all development is completed, so the redevelopment of housing in the Wangsimni New Town in the 15th district and the Huanghak district in the 13th district.

The 14th District Chengdu 5th District The redevelopment of the urban area was the largest, and the urban environment improvement project, 1 block Surin District, 5 blocks Euljiro 2. The development of the building parcels and the buildings changed greatly because it was developed separately. However, the buildings that were not developed in the Urban Environmental Improvement Project District were rapidly aging and there was no change in urban space.

In comparison, the designated district unit planning area after the restoration of Cheonggyecheon is divided into 1 block of Seoul City Government Building site, 10 blocks of Dongdaemun History and Culture Park, 2.4 blocks of 2 ~ 3 blocks, 5 block check district, 7.9 blocks, 8 Block bishop district, 10 block Dongdaemun historical cultural park district, 14 block new district The change of urban space was few.

Second, the analysis of the parcels that can be constructed in 2000 and 2018 and the change of road structure and shape after the restoration of Cheonggye Stream in 2005 after the demolition of the Cheonggyecheon highway in March, 1969, The total area of ​​the entire Cheonggyecheon area, which was set as the area, increased from 3,257,555㎡ in 2000 to 3,280,025㎡ and 22,670㎡ in 2018, and the total land area increased by 2,157,078㎡ and 15,211㎡ in 2018 from 2,141,867㎡ in 2000, respectively. As a result, the area surrounding the Cheonggyecheon area and the area of ​​the Cheonggyecheon area increased due to the widening of the main road and expansion of the Seoul city hall plaza.

The urban space around Cheonggyecheon changed the biggest shipping factor of Cheonggyecheon restoration after the demolition of the Cheonggyecheon highway in March, 1969. As a result of the change of road structure and shape and river restoration, It increased 149,881 ㎡ according to the restoration of Cheonggyecheon to 165,234 ㎡ from the river 15,354 ㎡. It not only increased the area of ​​the river but also affected the development of the nearby Cheonggyecheon stream and urban policies and plans. As the Cheonggyecheon stream was restored, the Cheonggye highway was demolished and the area decreased from 1,100,134m2 in 2000 to 957,712m2 in 2018.

Third, changes in urban policy and planning and urban organization have also affected buildings. In 2000, the building area was 1,283,755㎡ and the coverage rate was 59.94%. After the Cheonggyecheon Restoration Project, the construction area decreased by 9,540 ㎡ to 1,203,288 ㎡ in 2018, and the coverage rate also decreased by 4.15% to 55.78%. As the Cheonggyecheon restoration project has changed the surrounding buildings, the volume ratio has risen and the cover ratio has decreased by 4.15% due to the enlargement of the buildings and the stratification of the buildings.

As discussed above, this study aims to compare and analyze the effect of the Cheonggyecheon restoration project on the urban space around Cheonggyecheon with physical objective data. Unlike previous studies, this study compares the year 2018 and 2000 after 13 years after the restoration project of Cheonggyecheon, and it is meaningful to analyze the whole area of ​​restoration of Cheonggyecheon 5.84km. 2002년 당시 이명박 서울시장 후보는 청계천 복원을 위해 청계고가를 철거 할 것을 주장하였다. 2000년대 하루 12만대 차량이 다니던 고가도로가 없어질 경우 발생할 교통체증, 20만 명에 이르는 청계천 주변상인들의 생존문제로 논란이 일었지만 2002년 이명박 시장당선과 함께 청계천 복원 사업은 속도를 내기 시작했다. 2003년 7월 1일 청계고가는 34년 만에 철거에 들어갔다. 착공한지 2년 3개월만인 2005년 10월 1일 복원공사가 완료되었다.

차량으로 가득 찼던 장소에 도심 속 작은 자연인 물길을 환영하는 시민들과, 생활 터를 잃은 시민들 등 청계천복원으로 인해 좋은 점과 나쁜 점이 생겨났다. 청계천이 인위적으로 복원된 지 어느덧 13년이라는 시간이 지났다. 어느덧
