Ⅰ. Background and Aims of Research
o The urban (housing) development is essential for providing a living environment and area for the people, and for enabling them to lead a convenient life. However, it has tended to damage environment, destroying green lands and trees of the target area, and generating cut slopes by transforming topography.
o The purpose of this study is to examine the current status of domestic urban (housing) development projects, and suggest a sustainable development plan. We investigated various environmental impacts of urban (residential area) development projects based on the environmental impact assessment reports.
Ⅱ. Method and Scope
o This study investigated based on the 126 housing development projects from 2011 to 2020. We studied the development status by each self-governing province, damage rate of areas of first and second-grade ecological status and that of steep slopes after the development, the area released from the Green Belt, and also land use changes.
ㅇ Furthermore, we analyzed the distribution of air pollutant and malodor -emitting facilities around the project site (impact area 1, 3, 5km2) that may affect the settlement conditions of the residents.
Ⅲ. Results and Discussion
o It was found out that the housing development was steadily increasing, and major development areas are Gyeonggi-do, Gyeongsangbuk-do, Gyeongsangnam-do.
o The area of deforestation tends to decrease, and the damaged area was large in Gyeonggi-do and Gyeongsangbuk-do. The proportion of steep slopes of more than 20 degrees or 25 degrees has been increasing si
