Consideration of GREENAREARATIO When Establishing an Urban Development Plan

Abstract

Purpose: Just as the natural environment is vital for people to live in, the park and green area, which are indicators for eco-friendly development, are essential when proceeding with urban development projects. Therefore, this study reviewed focusing on the park and green area ratio in the environmental impact assessment for urban development projects. Through this, we intended to provide a comprehen-sive guideline for environmental land use planning and design for urban development or residential land development projects and to guide plans and designs based on this. Method: The analysis was based on the environmental impact assessment, which was investigated for 145 urban development projects for 18 years from 2003 to 2020. We conducted a one -way ANOVA analysis to determine the difference between the green area rate by year, the green area rate by region, the population density by region, and the park area per person by region. Post-hoc analysis was per-formed by the Scheffe test. To conduct the above statistical analysis, we used the Spss Statistics 21 sta-tistics program. Results: The number of consultations on environmental impact assessment for urban development projects by year was the highest in 2006 and 2008, with 14 cases(9.66%). The green area rate by year was as high as 25.09% in 2005, 24.88% in 2007, and 22.73% in 2009. The green area rate by region was the highest in the Gangwon area with 22.63%, followed by 20.47% in the metropolitan area, 19.59% in the Honam area, and 19.51% in the Chungcheong area. The population density by region was the high-est with 2.10(person/m2) in the metropolitan area. Next the Gangwon area was 1.99(person/m2) and the Southeast area was 1.80(person/m2). The park area per person by region was the largest in the Honam area, with 10.93m2. Conclusion: The area of parks and green spaces is seen as the minimum standard stipulated by law. However, the high green area ratio and the difference in population density by region during active ur-ban development projects are to create a pleasant residential environment. Therefore, in a place with high population density, it is necessary to establish a high standard for securing green space to create a comfortable living environment. Also, in the case of parks, the location is essential as well as the area. Since green areas on slopes excluding parks in the green area ratio are difficult to use, we insist that green areas on slopes should be reduced, and park areas should be set high to create a pleasant resi-dential environment.
